WEBVTT 1 00:00:00.000 --> 00:00:05.610 Unknown: There we are. Alright. Welcome, everyone to TC trs 2 00:00:05.670 --> 00:00:09.990 refresher training. It's been a couple of years since this has 3 00:00:09.990 --> 00:00:14.250 been done. And these slides have been updated for some new things 4 00:00:14.250 --> 00:00:19.560 that we do around the facility. And you can see here the picture 5 00:00:19.560 --> 00:00:23.940 of the system that was taken about 2004, shortly after 6 00:00:23.940 --> 00:00:30.240 delivery. And I'll show this picture again, slides down the 7 00:00:30.240 --> 00:00:34.500 road, and we'll go over some of the big pieces of it and call 8 00:00:34.500 --> 00:00:38.460 out what they are. So you'll be able to recognize them next time 9 00:00:38.460 --> 00:00:42.480 you're in the punk house, doing a walkthrough or for whatever 10 00:00:42.480 --> 00:00:50.670 reason. Alright, so we're going to talk about the purpose of the 11 00:00:50.670 --> 00:00:56.400 TC trs at Le who the users are. Again, we're going to call out 12 00:00:56.400 --> 00:00:58.800 the major components of the system and show you where they 13 00:00:58.800 --> 00:01:01.800 are, how to recognize them. We're going to talk about 14 00:01:01.800 --> 00:01:06.420 management and tracking of dt operations, management of the T 15 00:01:06.420 --> 00:01:12.960 CTRs. And then we'll have a go over not all the operations but 16 00:01:12.960 --> 00:01:16.740 some specific operations that are important to us. And 17 00:01:16.740 --> 00:01:22.290 finally, at the end, we'll have the impact of TC trs stops, 18 00:01:22.890 --> 00:01:28.020 right and in the context of a spherical cryo DP shot day 19 00:01:28.020 --> 00:01:33.600 because that's what's most important to us. Right, so the 20 00:01:33.600 --> 00:01:38.100 TC TRS is an acronym for target chamber tritium recovery system. 21 00:01:39.270 --> 00:01:43.050 And even though it's named for the target chamber, it provides 22 00:01:43.050 --> 00:01:47.520 services for all all throughout the Omega facilities. And 23 00:01:48.660 --> 00:01:54.030 somebody's mic is open. Let's get that. Let's see. Check your 24 00:01:54.030 --> 00:01:56.670 microphones and make sure they're closed. Thank you. 25 00:01:58.080 --> 00:02:01.500 Right, the TC TRS is operated by a cryo and trading facility 26 00:02:01.500 --> 00:02:06.330 staff and built by chemical design in Lockport, New York and 27 00:02:06.330 --> 00:02:10.740 it's in the pumphouse room 150 B. Right, the purpose of the TC 28 00:02:10.740 --> 00:02:16.500 TRS is to absorb dt from omega operations experiments and 29 00:02:16.500 --> 00:02:22.080 decontamination efforts, right because this is a activity 30 00:02:22.080 --> 00:02:26.910 that's gotten away from us and can't be returned to the DT 31 00:02:26.910 --> 00:02:30.480 inventory in the CryoEM trading facility. So it's it's just 32 00:02:30.480 --> 00:02:36.450 waste contamination that we have to capture and then deliver away 33 00:02:36.450 --> 00:02:40.830 from the facility. Right, we have limits to how much activity 34 00:02:40.830 --> 00:02:45.870 we can release to the stack. 2.2 curious for you here, Walter and 35 00:02:45.870 --> 00:02:51.690 talk about this in his annual redcon trading. Right. We're 36 00:02:51.690 --> 00:02:55.830 licensed by government authorities for 2.2 curIs. And 37 00:02:55.830 --> 00:03:02.220 the TC trs, we recovered for last year 2021. We pulled out 38 00:03:02.220 --> 00:03:08.820 9.7 curIs out of TC TRS and RSU came over and picked it up and 39 00:03:08.820 --> 00:03:13.650 I'll show you a little bit more down the slide deck here how 40 00:03:13.650 --> 00:03:21.360 that happens in the pump house. Right. So we actually release 41 00:03:21.540 --> 00:03:26.670 about 10% of our annual limit according to EPA monitor 42 00:03:27.810 --> 00:03:33.330 measurements, which is about you know, 200 or 250 militaries per 43 00:03:33.330 --> 00:03:38.340 year. So the TC trs does its work we wouldn't be able to 44 00:03:38.340 --> 00:03:44.580 operate here without it. Right who needs to know about the T 45 00:03:44.580 --> 00:03:50.580 CTRs. We do right shot directors TSOs ESTPs cart maintenance room 46 00:03:50.580 --> 00:03:54.720 and cryo and tritium facility personnel. We are all 47 00:03:54.960 --> 00:03:59.610 responsible for using and managing the TC trs. 48 00:04:03.870 --> 00:04:06.180 As you walk through the pumphouse, you'll see these 49 00:04:06.900 --> 00:04:11.370 major components of the TC trs right right in the middle of the 50 00:04:11.370 --> 00:04:15.030 system and labeled at the top that is the low pressure 51 00:04:15.030 --> 00:04:20.520 receiver and this is just a 40 cubic foot hollow volume that is 52 00:04:20.520 --> 00:04:24.600 maintained at low pressure by the blower which is in the 53 00:04:24.600 --> 00:04:29.910 square box at the bottom center right. So the blower is like a 54 00:04:29.910 --> 00:04:34.800 two stage rotary vane pump that pulls everything out of that low 55 00:04:34.800 --> 00:04:39.810 pressure receiver sends it out to the pre heater and palladium 56 00:04:39.810 --> 00:04:44.310 reactor sections on the on the on the right hand side there 57 00:04:44.310 --> 00:04:50.490 those are vessels and then the that same flow is returned again 58 00:04:50.820 --> 00:04:55.410 to the low pressure receiver and it just in a big loop circles 59 00:04:55.410 --> 00:04:58.680 round and round and you say well, what good is that and well 60 00:04:58.680 --> 00:05:02.910 we'll go over that and In just a minute. On the left side, we 61 00:05:02.910 --> 00:05:07.590 have the mole sieve bed dryers, and the condensate vessel where 62 00:05:07.590 --> 00:05:13.410 activity is ultimately stored and then removed during the 63 00:05:13.440 --> 00:05:19.290 regeneration process. Again, just a closer look at that low 64 00:05:19.290 --> 00:05:22.950 pressure receiver in the middle back of the system ti 8410 You 65 00:05:22.950 --> 00:05:26.940 see it there, it's just a hollow vessel, the blower, which you 66 00:05:26.940 --> 00:05:30.840 can see in the picture there, right I pull the top off the 67 00:05:30.840 --> 00:05:35.430 box, I can show you the blower inside and everything that you 68 00:05:35.430 --> 00:05:40.200 pump or purge on omega has to come through this blower and 69 00:05:40.200 --> 00:05:46.320 it's next down to one and a half inch, you know schedule 45 And 70 00:05:46.320 --> 00:05:48.990 it goes out to the reactor and it comes back to the ballast 71 00:05:48.990 --> 00:05:52.800 volume again and it just goes round and round and round. And 72 00:05:55.860 --> 00:06:00.090 look let's go to the next slide. And go over it in a little more 73 00:06:00.120 --> 00:06:07.560 detail. Here's another look at the same operation. This is the 74 00:06:07.590 --> 00:06:11.160 the reactor loop which includes again the ballast volume, the 75 00:06:11.160 --> 00:06:16.800 blower and the reactor 50 SCFM, this gas just goes round and 76 00:06:16.800 --> 00:06:25.530 round. And any dt or hydrogen products that come into the 77 00:06:25.530 --> 00:06:33.030 system like tritium, or methane is burned into water, you can 78 00:06:33.030 --> 00:06:38.340 see the the balanced equation for water at the bottom there 79 00:06:38.370 --> 00:06:43.170 hydrogen and oxygen are burned into DTO in the presence of this 80 00:06:43.170 --> 00:06:48.060 palladium reactor. Right there's 308 pounds of palladium in 81 00:06:48.060 --> 00:06:52.950 there. And this palladium just facilitates this, this reaction 82 00:06:52.950 --> 00:07:03.300 this burning of hydrogen products into water the PLC 83 00:07:03.360 --> 00:07:08.040 controls flow through the system via pressure limits, you can see 84 00:07:08.280 --> 00:07:12.600 the 40 cubic foot buffer tank is connected to the PLC and a low 85 00:07:12.600 --> 00:07:16.950 pressure of minus 1.5 psi is maintained in that bad balanced 86 00:07:16.950 --> 00:07:22.800 volume at all times. And when flow comes in, right mass flow 87 00:07:22.800 --> 00:07:26.730 comes into the buffer tank and equal quantity has to flow out 88 00:07:27.630 --> 00:07:31.770 to the dryer section you see at the bottom right there. So I put 89 00:07:31.770 --> 00:07:36.360 at the top there q n equals Q out because everything that 90 00:07:37.050 --> 00:07:41.340 comes in has to the equal quantity goes out out the back 91 00:07:41.340 --> 00:07:44.490 to the dryer section, but also everything that comes into this 92 00:07:44.490 --> 00:07:48.660 reactor section. Right The DT and hydrogen products are all 93 00:07:48.660 --> 00:07:53.400 turned into water. And so in the dryer section it'll all be 94 00:07:53.400 --> 00:08:01.170 trapped. And and let's go on to that right here. Right this is 95 00:08:01.170 --> 00:08:05.910 where activity from omega is ultimately traps DTO and water 96 00:08:05.940 --> 00:08:10.740 is reversibly absorbed on drier media. And you can see what it 97 00:08:10.740 --> 00:08:16.350 looks like there next to the penny we have 145 or 300 pounds 98 00:08:16.350 --> 00:08:21.120 of media inside each vessel vessels about six feet tall 14 99 00:08:21.120 --> 00:08:27.540 inches wide. And these there are three of these vessels on the 100 00:08:27.540 --> 00:08:30.300 system to maximize system availability. So 101 00:08:30.300 --> 00:08:35.670 one is always in service for absorbing water one is may or 102 00:08:35.670 --> 00:08:40.140 may not be in a saturated in in the region state and another is 103 00:08:40.140 --> 00:08:44.190 in isn't a isn't a trim state which is another part of the 104 00:08:44.190 --> 00:08:50.190 region operation right but these regions occur concurrently with 105 00:08:50.190 --> 00:08:54.840 the with the main process which helps us which maximizes the 106 00:08:54.840 --> 00:08:59.490 availability of the system. Right since all the tritium the 107 00:08:59.490 --> 00:09:05.910 DTO is trapped on the Mole cinfed dryers only clean dry gas 108 00:09:05.940 --> 00:09:09.780 is allowed to proceed to the stack. And again emissions are 109 00:09:10.350 --> 00:09:14.370 read are limited to about 10% of the annual limit in this way. 110 00:09:16.230 --> 00:09:25.710 Let's see. So limitations of the TC trs, it's flow limited again 111 00:09:25.710 --> 00:09:30.870 I told you about the blower and its neck down to 1.5 inch NPT 112 00:09:30.870 --> 00:09:36.570 pipe so there's a limit to how much gas you can squeeze through 113 00:09:36.570 --> 00:09:42.480 that small diameter. We're water load limited to about 20 kilos 114 00:09:42.480 --> 00:09:46.710 of water on a mold sieve bed right that 300 pounds of mold 115 00:09:46.710 --> 00:09:50.850 sieve can only hold so much water and then it's it's ready 116 00:09:50.850 --> 00:09:55.530 for regeneration. And it takes about 40 or 50 days between 117 00:09:55.530 --> 00:10:00.000 regions to saturate that bet most of the water comes from 118 00:10:00.000 --> 00:10:03.870 relative humidity, the almost all of it as a matter of fact 119 00:10:03.870 --> 00:10:07.800 comes from relative humidity that exists, you know, in, in 120 00:10:07.800 --> 00:10:13.050 the air that we use to purge and, and pump volumes on omega. 121 00:10:13.710 --> 00:10:20.400 Only a tiny fraction of the water is actually DTO or Tritiya 122 00:10:20.400 --> 00:10:25.020 did water and that's why the system is so big because it's 123 00:10:25.020 --> 00:10:34.230 made really to handle water. Each pump oh, let's talk about 124 00:10:34.860 --> 00:10:39.540 what have I got here omega nitrogen purge. Right each pump 125 00:10:39.540 --> 00:10:44.370 has a one cubic foot per minute nitrogen purge on it and this is 126 00:10:44.370 --> 00:10:50.730 important for the ESO. To know this. The nitrogen purge from 127 00:10:50.730 --> 00:10:54.390 four pumps, if you happen to be operating for pumps will slowly 128 00:10:54.390 --> 00:10:58.860 displace the oxygen in the TC trs which is required for 129 00:10:58.860 --> 00:11:06.570 operations. Right, if I go back to this slide, right at the top, 130 00:11:06.570 --> 00:11:12.030 you'll see up near the TC trs blower, there's a oxygen monitor 131 00:11:12.030 --> 00:11:16.380 and an oxygen bleed on the system to provide oxygen for 132 00:11:16.380 --> 00:11:21.690 this chemical reaction at all times, and if you operate too 133 00:11:21.690 --> 00:11:27.270 many, or for all four omega pumps to TC trs, the nitrogen 134 00:11:27.270 --> 00:11:31.860 will, you know, slowly reduce this oxygen concentration over 135 00:11:31.860 --> 00:11:36.180 time and that can impact the performance and efficiency of 136 00:11:36.180 --> 00:11:39.900 the system. And so that's why the ESO that's why I call you up 137 00:11:39.900 --> 00:11:43.440 on the phone and ask you why are you running four pumps and let's 138 00:11:43.440 --> 00:11:47.760 switch to three. That's the normal arrangement. And, and 139 00:11:47.760 --> 00:11:51.630 that's how and that's how we prefer to see it at all times. 140 00:11:52.980 --> 00:11:59.850 Keep in mind that small air leaks into the T CTRs can 141 00:11:59.880 --> 00:12:05.820 saturate emulsive bed you know earlier than we expect. And I'm 142 00:12:05.820 --> 00:12:09.390 just showing a little math at the bottom there were a small 143 00:12:09.390 --> 00:12:16.110 leak of 6.5 cubic feet per minute into tea CTRs in one day 144 00:12:16.110 --> 00:12:21.270 can add two kilos of water. Right. And so that's 10% of the 145 00:12:21.270 --> 00:12:28.650 most of bed load per day with a small leak like that. And so, we 146 00:12:28.650 --> 00:12:33.150 do monitor system oxygen and flow rates on a day to day basis 147 00:12:33.180 --> 00:12:40.050 and and to alert us to to that sort of failure mode when it 148 00:12:40.050 --> 00:12:51.690 happens. All right. The TC trs should be connected at all 149 00:12:51.690 --> 00:12:56.640 times, right? The Omega pumps should be connected to TCTs. If 150 00:12:56.640 --> 00:12:59.790 it's not everyone should know about it and the system should 151 00:12:59.790 --> 00:13:01.770 have already been decontaminated. 152 00:13:02.850 --> 00:13:07.020 Right? If omega is not decontaminated and the T CTRs 153 00:13:07.020 --> 00:13:10.980 stops operating, we need to be very careful. Alright, an 154 00:13:10.980 --> 00:13:17.280 example of this is if we have DT operations on a Tuesday, and 155 00:13:17.280 --> 00:13:21.570 then we're still operating the system on Wednesday. And then on 156 00:13:21.570 --> 00:13:26.670 Thursday, the TC trs stops operating for some reason a 157 00:13:26.670 --> 00:13:31.350 failure occurs we need to be very careful right because the 158 00:13:31.350 --> 00:13:34.560 target chamber may not have been decontaminated and there might 159 00:13:34.560 --> 00:13:39.210 be quite a bit of activity trapped on the cryo PUMP PUMP 160 00:13:39.210 --> 00:13:45.690 PUMP cryo pump number one as I show in this schematic there. So 161 00:13:45.690 --> 00:13:49.170 every effort needs to be taken in this scenario to keep the 162 00:13:49.170 --> 00:13:54.270 target chamber under vacuum and keep the cryo pump cold. Right 163 00:13:54.270 --> 00:13:58.590 the ESO knows the contamination status of the target chamber in 164 00:13:58.590 --> 00:14:02.340 the cryo pump. It's given on their GUI at the White at their 165 00:14:02.340 --> 00:14:07.890 watch station. And so, if you learn that the TC TRS is not 166 00:14:07.890 --> 00:14:10.800 operating this is this is the first thing that you want to 167 00:14:10.800 --> 00:14:13.800 think of what is the contamination status of omega 168 00:14:14.340 --> 00:14:19.110 and how should I and then you can proceed from that from that 169 00:14:19.110 --> 00:14:29.790 status. All right. DT operations and the TC trs are managed, 170 00:14:31.080 --> 00:14:39.780 right. So M M 66 Is the TC trs usage policy and it's still 171 00:14:40.590 --> 00:14:44.940 still active, we still follow it even though it hasn't been 172 00:14:45.180 --> 00:14:55.680 edited for quite some time. We've added new services and we 173 00:14:55.680 --> 00:14:59.880 have a new tool called the DT ops tracker that is used to help 174 00:14:59.880 --> 00:15:03.330 us Manage DT operations. Alright, it's your 175 00:15:03.330 --> 00:15:07.680 responsibility as an ESO, or CART maintenance from staff, 176 00:15:07.680 --> 00:15:11.490 Crown trading facility staff, the shop director to review and 177 00:15:11.490 --> 00:15:15.240 understand the status of dt operations when requesting, 178 00:15:16.230 --> 00:15:20.460 pumping or purging and deaqon services and procedures have 179 00:15:20.460 --> 00:15:26.460 been updated to instruct you in the use of this DTS tracker, 180 00:15:26.970 --> 00:15:31.050 which I'm going to show you a little more detail right now, on 181 00:15:31.050 --> 00:15:38.040 the left side, there you can see the user the TC trs usage policy 182 00:15:38.040 --> 00:15:43.410 matrix, right. And this is still valid, we used to try to look at 183 00:15:43.410 --> 00:15:47.580 this, or we would look at this when requesting and managing DT 184 00:15:47.580 --> 00:15:51.780 operations in the past. But that whole matrix, you know, 100 or 185 00:15:51.780 --> 00:15:56.850 so possible combinations that are given in that table has all 186 00:15:56.850 --> 00:16:04.680 been distilled into the DT apps tracker. Hold on one second, 187 00:16:04.890 --> 00:16:09.420 please, folks, I'm just going to respond to this to a message 188 00:16:09.420 --> 00:16:10.500 that I have here. 189 00:16:15.690 --> 00:16:26.160 I apologize. Alright, so but this is just a memory tool, a 190 00:16:26.160 --> 00:16:30.690 logic tool, and it's only good. You know, it's only abused to us 191 00:16:30.690 --> 00:16:37.080 if we if we use it with some discipline, right. Again, 192 00:16:37.080 --> 00:16:40.080 procedures have been updated to include instructions to 193 00:16:40.080 --> 00:16:42.900 communicate with the shot director and update the status 194 00:16:42.900 --> 00:16:47.790 of facility operations. With this, with this new tracker 195 00:16:47.790 --> 00:16:52.920 tool, let's talk about it some more. Right, this is the viewer 196 00:16:52.920 --> 00:16:56.400 only version of the tracker, which is available to all of us 197 00:16:56.400 --> 00:17:01.950 on the operations website. So you can click on the link, and 198 00:17:01.950 --> 00:17:06.750 you should be able to add a glance, see the TT operations 199 00:17:06.750 --> 00:17:12.240 tracker and the current status of all of the manage to DT 200 00:17:12.240 --> 00:17:23.310 operations that we prove that the TC trs supports. Right. The 201 00:17:23.310 --> 00:17:30.330 shot director has a version of the DT ops tracker in in Prague 202 00:17:30.330 --> 00:17:33.990 panel at his desk and the shot director is the only one who can 203 00:17:33.990 --> 00:17:38.370 change it. Right the operations website is a viewer only version 204 00:17:38.370 --> 00:17:42.810 but the shot director is the manager of dt operations. And so 205 00:17:43.200 --> 00:17:45.870 it is only through the shot director that you will be able 206 00:17:45.870 --> 00:17:53.550 to change the status of, of this of this table. Right that ops 207 00:17:53.550 --> 00:17:56.820 tracker communicates the current status of dt operations to 208 00:17:56.820 --> 00:18:02.160 everyone who wants to know. And here we see that the Omega 209 00:18:02.160 --> 00:18:06.180 target chamber purge has been put in service, right with the 210 00:18:06.180 --> 00:18:12.660 green, the green color and the inservice taxed. And when the 211 00:18:12.660 --> 00:18:17.220 shot director did that, the other services all turned red 212 00:18:17.250 --> 00:18:20.670 and the text change to prohibited right because it 213 00:18:20.670 --> 00:18:26.250 automatically obeys the logic given in this table that we saw 214 00:18:26.550 --> 00:18:33.450 on the previous slide. The only connection to system hardware 215 00:18:33.450 --> 00:18:38.610 that the tracker has is the TC trs running bit and we see that 216 00:18:38.610 --> 00:18:42.090 with the green color and in the button at the top left there it 217 00:18:42.090 --> 00:18:47.280 says TC trs running. Right this is just a pressure transducer 218 00:18:47.280 --> 00:18:53.910 that sets a bit it senses low pressure and tells and sets this 219 00:18:53.940 --> 00:18:57.450 color and running bit to let everyone know that the system is 220 00:18:57.450 --> 00:19:02.010 still operating when the TC trs blower stops and the system 221 00:19:02.010 --> 00:19:06.840 shuts down the pressure switch trips, and the look of this 222 00:19:06.840 --> 00:19:11.520 tracker is going to change. Right The status will turn red 223 00:19:11.520 --> 00:19:15.480 it'll say TC trs stop and I'll show you what that looks like. A 224 00:19:15.480 --> 00:19:20.940 little bit further down the slide deck here. I do have some 225 00:19:20.940 --> 00:19:25.500 ideas about adding. So a little bit more features to the 226 00:19:25.500 --> 00:19:30.030 tractor. We might add in the future if people like it or want 227 00:19:30.030 --> 00:19:35.370 it the contamination status of the cryo pump and the target 228 00:19:35.370 --> 00:19:40.410 chamber and and maybe even the connection status because the 229 00:19:40.410 --> 00:19:44.130 tracker does not tell you. Right it tells you that the TC TRS is 230 00:19:44.130 --> 00:19:49.260 running but it doesn't tell you if omega is connected to it. 231 00:19:51.600 --> 00:19:58.620 Alright, this begins specific operations portion of the talk 232 00:19:59.160 --> 00:20:02.010 and we're going to talk about specific operations and 233 00:20:02.010 --> 00:20:05.730 hopefully dispel some misconceptions about what the TC 234 00:20:05.730 --> 00:20:12.450 TRS and how things happen around the facility. Here we see the 235 00:20:12.450 --> 00:20:17.220 target chamber purge operation indicated in the DT abstractor. 236 00:20:17.520 --> 00:20:20.760 And you can see in the simplified schematic there that 237 00:20:20.790 --> 00:20:26.160 the recycle option, right, the PLC controlled recycle option 238 00:20:26.160 --> 00:20:32.190 has been shut and the loop has become a single pass loop or 239 00:20:32.190 --> 00:20:35.400 it's not a loop at all it's a single pass straight out to the 240 00:20:35.400 --> 00:20:40.170 dryer section. Right and the flow the flow is going to be 241 00:20:40.170 --> 00:20:47.940 about 50 s CFM for this operation. And I do want to tell 242 00:20:48.150 --> 00:20:53.700 ESLs and shock directors right that this DT operation ends when 243 00:20:53.700 --> 00:20:58.740 the purge to TC trs ends right so it's two hours or four hours. 244 00:20:59.160 --> 00:21:02.730 And when you are finished with that purge the TC TRS and you 245 00:21:02.730 --> 00:21:09.000 switch over to purging to stack, right. That's not included in 246 00:21:09.000 --> 00:21:13.680 the DT operation and you can update the tracker when the 247 00:21:13.680 --> 00:21:15.180 purge ends. 248 00:21:16.800 --> 00:21:29.370 Alright, so I want to look at this p&i D schematic and talk 249 00:21:29.370 --> 00:21:33.720 about the target chamber purge option a little bit more. There 250 00:21:33.720 --> 00:21:37.740 you can see the Omega pumps in the picture. Right these green 251 00:21:37.740 --> 00:21:44.130 boxes on the left are the main turbo cryo and auxiliary pump 252 00:21:44.670 --> 00:21:49.890 lines the large diameter I think they're 1212 inch vacuum lines 253 00:21:49.890 --> 00:21:53.730 down there in the in the plenum behind the car to the pump 254 00:21:53.730 --> 00:21:57.120 house. At the top left, you can see that's the connection to 255 00:21:57.120 --> 00:22:01.650 stack and at the top right that is the connection to TC trs. 256 00:22:02.820 --> 00:22:10.740 These blue boxes here are the Omega pumps. And when we purge 257 00:22:11.070 --> 00:22:13.980 the target chamber you can see the pumps are not involved, 258 00:22:14.040 --> 00:22:18.390 right? You just connect the target chamber through that 259 00:22:18.390 --> 00:22:23.520 large diameter line. You bypass the pumping package and connect 260 00:22:23.640 --> 00:22:27.540 directly to the low pressure receiver on TC trs, so does the 261 00:22:27.540 --> 00:22:33.090 TC trs that provides suction for this decon activity. And again, 262 00:22:33.090 --> 00:22:38.160 that is 50 cubic feet per minute. Right. And so we'll do 263 00:22:38.160 --> 00:22:43.470 this for two hours or four hours. Coincidentally, I believe 264 00:22:43.470 --> 00:22:47.550 this is this operation was started this morning, and it's 265 00:22:47.550 --> 00:22:53.430 operating for four hours right now. But when that four hour 266 00:22:53.430 --> 00:22:58.830 Purge is over, the purge will switch to stack, right and the 267 00:22:58.830 --> 00:23:03.150 stack has its own blower and provides its own suction. And 268 00:23:03.210 --> 00:23:09.810 that's how that will look when the Decon activity is over. And 269 00:23:09.810 --> 00:23:13.680 the tracker has been updated right this is not part of the 270 00:23:13.680 --> 00:23:18.720 target chamber purge activity not part of the DT operation 271 00:23:18.720 --> 00:23:24.000 when you switch to the stack. Right there's been some 272 00:23:24.000 --> 00:23:30.870 misunderstandings about that in the past All right. So, here is 273 00:23:30.900 --> 00:23:39.300 a picture of a inch and a half schedule 40 bellows line that 274 00:23:39.300 --> 00:23:45.180 has been subjected to too much pressure as you can see and this 275 00:23:45.180 --> 00:23:50.550 is did not happen here to the TC trs but is a picture I found 276 00:23:50.730 --> 00:23:55.380 what could happen if we don't manage a pumping operations 277 00:23:55.380 --> 00:24:00.930 correctly on the system. Right because when you pump right you 278 00:24:00.930 --> 00:24:07.740 can pump the stack right you can pump the tea CTRs note that one 279 00:24:07.740 --> 00:24:12.720 pump is used for the target chamber pump down in the past 280 00:24:12.780 --> 00:24:16.320 we've had the target chamber pump down when we're add more 281 00:24:16.320 --> 00:24:21.000 than one pump and that results in stuffing too much gas into 282 00:24:21.000 --> 00:24:27.960 the T CTRs too quickly and we want to avoid you know blowing 283 00:24:27.960 --> 00:24:34.470 up this bellows on the outlet of the of the TC trs blower because 284 00:24:34.470 --> 00:24:38.910 that is an expensive and discipline difficult repair for 285 00:24:38.910 --> 00:24:45.390 us. And so when you do pump down the target chamber to TC trs, 286 00:24:45.390 --> 00:24:48.540 you need to be careful that you're only operating one pump 287 00:24:48.900 --> 00:24:52.560 and really you should only be doing this if the target chamber 288 00:24:52.560 --> 00:24:57.210 has not been decontaminated right otherwise you should be 289 00:24:57.210 --> 00:25:01.500 pumping it to stack right the the normal path for pumping down 290 00:25:01.500 --> 00:25:05.940 the target chamber is to stack because we presume or assume 291 00:25:05.940 --> 00:25:10.500 that it was decontaminated when you vented it up in the first 292 00:25:10.500 --> 00:25:18.420 place. Okay, cart maintenance room services in the cart 293 00:25:18.420 --> 00:25:23.250 maintenance room. We don't. We have carts right with DT targets 294 00:25:23.250 --> 00:25:28.080 or carts that have spent, have been shot and they're 295 00:25:28.080 --> 00:25:34.650 contaminated. And we provide decon service for the cart 296 00:25:34.650 --> 00:25:39.180 maintenance room the TC trs does, and they do that with a 297 00:25:39.480 --> 00:25:45.210 venting and pumping operation into cart maintenance room, not 298 00:25:45.210 --> 00:25:47.880 a continuous purge, right. 299 00:25:54.300 --> 00:26:00.450 Room 157 and the TC trs interconnect line. As you walk 300 00:26:00.450 --> 00:26:04.170 down the galley passageway you will notice above your heads and 301 00:26:04.170 --> 00:26:07.530 to the left a little bit if you're walking South a 200 foot, 302 00:26:07.830 --> 00:26:11.250 two inch stainless steel right line which I've got a little red 303 00:26:11.250 --> 00:26:19.680 arrow on right, put it right there. So this 200 foot run 304 00:26:19.950 --> 00:26:24.990 connects rule 157 to the low pressure receiver on TC trs, and 305 00:26:24.990 --> 00:26:32.340 we use this for decontaminating from time to time. The FTS or 306 00:26:32.340 --> 00:26:37.590 DTH PS the large glove boxes in room 157, though that's somewhat 307 00:26:37.590 --> 00:26:42.060 rare. More commonly, it's used for the happy glove box, which 308 00:26:42.060 --> 00:26:45.870 you see there in the middle of the of the slide. And this is 309 00:26:45.870 --> 00:26:52.470 the location from which DT targets ambient DT targets are 310 00:26:52.470 --> 00:26:57.390 delivered to omega. It's also a place where an operator can 311 00:26:58.200 --> 00:27:05.820 mount DT filled glass targets. And the suction from TC trs just 312 00:27:05.820 --> 00:27:09.300 provides a low pressure environment on the glovebox 313 00:27:09.300 --> 00:27:15.240 there and keeps the activity away from the operator. And this 314 00:27:15.240 --> 00:27:21.360 is a very common di t operation. And you can see what that 315 00:27:21.360 --> 00:27:24.690 service looks like on the tracker right I'm showing four 316 00:27:24.690 --> 00:27:30.960 operations simultaneously going and you can see some of the 317 00:27:30.960 --> 00:27:36.930 other operations are prohibited from taking place while the 318 00:27:36.930 --> 00:27:47.040 happy glove boxes in service. Alright the cryo pump region is 319 00:27:47.040 --> 00:27:52.170 another important operation that the TC trs supports right there 320 00:27:52.170 --> 00:27:58.980 are two cleanup systems for the cryo pump region operation Omega 321 00:27:58.980 --> 00:28:02.370 pump one is usually the hot pump it's the pump that we use when 322 00:28:02.370 --> 00:28:07.200 we shoot cryo or Ambien DT shots right so that the same pump is 323 00:28:07.200 --> 00:28:12.930 always handling the activity and and that pump is used in a 324 00:28:12.930 --> 00:28:18.600 limited way for for pumping air. So a non DP shot days it's 325 00:28:18.600 --> 00:28:22.470 usually not in service, right that pump gets isolated for 326 00:28:22.470 --> 00:28:27.510 region and then the the pumping is turned off. Argon is float in 327 00:28:27.510 --> 00:28:30.630 to start warming up the pump and activity is carried to the 328 00:28:30.630 --> 00:28:36.570 scrubber in mcop. Most of the activity is absorbed in the 329 00:28:36.570 --> 00:28:42.150 scrubber in the top right but then the scrubber passes its 330 00:28:42.150 --> 00:28:49.110 effluent off to TC trs after that and the TC trs polishes up 331 00:28:49.110 --> 00:28:53.430 any activity that was not captured in the laptop scrubber 332 00:28:53.790 --> 00:28:57.840 and the ESO and Kryon tritium facility staff work together on 333 00:28:57.840 --> 00:29:04.110 this operation and so it has to be carefully coordinated and 334 00:29:04.110 --> 00:29:07.230 handled it's this is a this is a you know one of our higher 335 00:29:07.230 --> 00:29:12.180 activity operations. And I tried to show that with this graphic 336 00:29:12.180 --> 00:29:14.850 where you know most of the activity is connected here in 337 00:29:14.850 --> 00:29:19.770 the scrubber and then the TC trs provides the polishing service 338 00:29:20.160 --> 00:29:27.420 the activity is removed at a later time in a region process 339 00:29:28.230 --> 00:29:31.170 right here's another look at it there's discover on the cost of 340 00:29:32.070 --> 00:29:38.490 the pump regen effluent comes through these nickel bed and the 341 00:29:38.490 --> 00:29:42.930 circ iron bed seen here in the bottom of the system. Right 342 00:29:43.410 --> 00:29:47.010 activity from the target chamber goes on the pump down through 343 00:29:47.010 --> 00:29:49.650 the scrubber in the cob and then on to 344 00:29:49.680 --> 00:30:02.730 TC trs. Periodic Maintenance You've heard about TC trs most 345 00:30:02.730 --> 00:30:07.830 of bed regions, it's the last stop for contaminated waste 346 00:30:07.830 --> 00:30:09.570 before being removed from 347 00:30:10.950 --> 00:30:14.850 from the laboratory. Right this block diagram highlights the 348 00:30:14.850 --> 00:30:19.740 path activity takes. And the activity is diverted from the 349 00:30:19.740 --> 00:30:26.070 most of dryers we talked about. This most of bed dryer shown in 350 00:30:26.070 --> 00:30:30.990 the picture again, there's three of these on the TC trs skid, and 351 00:30:30.990 --> 00:30:36.240 300 pounds of Multivan inside and they're wrapped with heaters 352 00:30:36.240 --> 00:30:40.410 and cladding. Right so when the time comes, the saturated bed 353 00:30:40.410 --> 00:30:45.570 can be heated, and that we flow nitrogen through it. And the 354 00:30:45.750 --> 00:30:49.020 effluent from from the most of bed dryer goes through a 355 00:30:49.020 --> 00:30:52.860 condenser. And all the water that's been absorbed there, 356 00:30:52.950 --> 00:31:01.350 including the DTO will end up in a condensate vessel and trapped 357 00:31:01.350 --> 00:31:05.190 in this way. And then the effluent, right, the clean 358 00:31:05.190 --> 00:31:08.850 effluent just pass through another dryer. And then on to 359 00:31:08.850 --> 00:31:12.930 stack after that, right we're flowing clean, dry nitrogen the 360 00:31:12.930 --> 00:31:17.490 stack in the region process because all the water it gets 361 00:31:17.490 --> 00:31:25.260 condensed or trapped on the second dryer. Okay. Let me 362 00:31:25.260 --> 00:31:37.530 check. Okay. Let's talk about what happens and the response to 363 00:31:37.650 --> 00:31:43.860 TC trs stops. We'll talk about it in the context of cryo DT 364 00:31:43.860 --> 00:31:48.960 operations. And the short story here is that omega pumps are 365 00:31:48.960 --> 00:31:53.820 switched to stack automatically, except for the cryo line pump. 366 00:31:54.600 --> 00:31:58.950 And the ESO will be alerted to this condition by the GUI at the 367 00:31:59.220 --> 00:32:05.070 top so watch station. Right if the shop director has the DT ops 368 00:32:05.070 --> 00:32:08.910 tracker popped up on his screen, he'll also be alerted to this 369 00:32:08.940 --> 00:32:13.590 condition by the change in color on the operations tracker. 370 00:32:15.090 --> 00:32:20.670 Right. Services will be automatically isolated on the 371 00:32:20.670 --> 00:32:26.340 cryo line alarms messages will go out to cry on tritium staff 372 00:32:26.340 --> 00:32:29.340 and everyone will know about this condition pretty quickly. 373 00:32:30.630 --> 00:32:34.380 Here's what the Tracker will look like at the shot director's 374 00:32:35.940 --> 00:32:40.020 desk. It'll also look like this the viewer only version on the 375 00:32:40.050 --> 00:32:46.080 operations website. Right and so the running bit has set the 376 00:32:46.440 --> 00:32:52.170 color to red and the states have been changed to yellow to call 377 00:32:52.170 --> 00:32:56.250 attention to this. You know, this a warning condition that 378 00:32:56.250 --> 00:33:00.270 the system is not operating all of the states can still be 379 00:33:00.270 --> 00:33:02.880 changed and it works the same as before because it's just a 380 00:33:02.880 --> 00:33:06.750 memory tool and takes no action. It's only that the color is 381 00:33:06.750 --> 00:33:10.080 changed to alert everyone to that something is wrong 382 00:33:17.220 --> 00:33:23.880 in law cov This is what a simplified schematic of the cryo 383 00:33:23.880 --> 00:33:29.640 line and you've got the carts right in parking spaces or at 384 00:33:29.640 --> 00:33:35.160 the lower pylon handling DT cryo carts right and we provide this 385 00:33:35.250 --> 00:33:38.820 roughing manifold and backing manifold or connect to the cryo 386 00:33:38.820 --> 00:33:44.310 line and connected to TC trs in this way. This is how things 387 00:33:44.310 --> 00:33:50.910 should look on a cryo DT shot day. Right when in TC trs stops 388 00:33:50.910 --> 00:33:55.740 operating the cryo line will be stopped and isolated. Right and 389 00:33:55.740 --> 00:34:03.210 so you can think about this. There's no reason to panic right 390 00:34:03.210 --> 00:34:10.320 the targets in parking spaces and at the lower pylon even will 391 00:34:10.320 --> 00:34:14.940 be alright for a time while this pumping is not available. 392 00:34:15.540 --> 00:34:19.110 Because it'll just pump into this closed manifold and until 393 00:34:19.110 --> 00:34:23.490 the pressure builds up in the manifold which will take some 394 00:34:23.490 --> 00:34:29.460 time. We have some time to work the problem and and hopefully 395 00:34:29.550 --> 00:34:35.490 recover vacuum get the T CTRs. Running again and and move on 396 00:34:35.490 --> 00:34:42.480 with with operations. But that's the way things will go. When the 397 00:34:42.480 --> 00:34:47.760 system stops, that's what you should expect to happen. Right 398 00:34:47.760 --> 00:34:54.720 stopping the T CTRs. requires approval from from cryo and 399 00:34:54.720 --> 00:35:05.910 trading facility managers and Omega managers This is the link 400 00:35:06.000 --> 00:35:12.900 to relevant TC trs operate documentation like the usage 401 00:35:12.900 --> 00:35:20.760 policy and the cryo pump region procedure and then a schematic 402 00:35:20.790 --> 00:35:27.630 of the again the the cryo pump region setup with both the cops 403 00:35:27.630 --> 00:35:33.990 cover and the T CTRs more detail that is the end of the 404 00:35:33.990 --> 00:35:37.470 slideshow. I'm going to
