The evaporator#1 glovebox is leaking from the gloves, around the ports, and the base (possible more places).  It is evident that there were holes on the gloves.  When the glovebox is purged with Ar gas, one can feel that the gas is blown out from the base.   Solutions: New gloves are ordered from RENCO Co. (PO#TR189708).  New seals & glove port rings have been implemented.  More need to be done...

 See Evaporator_1 log entry

Evap1:  Cleaned and checked seals.  Oil level could not be clearly determined, but are consulting with pump group to check.

Evap2: Cleaned and checked seals. 

Thursday, August 01, 2024, 14:56

EVAP1:  Checked seal and no visible deterioration was observed.  Oil level in roughing pump was good.  Circulated argon to observe functionality of the gloves and to check appropriate gas flow. 

EVAP2:  Visually inspected the connections at the back of the evaporator.  A loose connection had been observed on the previous day but fixed.  Roughing pump running well and system operational.  The door seal could not be checked but it is working properly as evidenced by the fact that the evaporator was in use. No major maintenance required at this moment.

There is a pin hole water leak coming from the DIW supply pipe going into the ISAC B1 hot lab - rm 06. It appears to be on the solder / joint. The leak is very small at this point. Mostly just a drip. 

Fault 12701

Same pipe that had a leak in the cold lab ~1 month ago now has leak in SEM lab.

Small amount of water on floor and ceiling tile was brown and very bulgey - looked like it was about to collapse.

Small poke and the whole thing fell out. 

Tile was very brown, damp and moldy as one can see in photos

mold indicates this was a slow build up and must have started a while ago.

one can see entire pipe through hallway does not look in great condition - similar to patch where leaked.

recommend entire pipe gets replaced.

will be patched up for now and replaced at end of month.

The sink to the rear of the cold lab beneath the paper towel dispenser has sprung a leak. The leak is most apparent when the hot water tap is used. It appears right at the back, behind the sink basin where the pipes meet the counter top to faucet.

Entered under fault report 12204 

Currently 'Tagged' with bags over the handles to discourage use..

I've setup a box of cloth booties for entering the hotlab.  They are
washable so please use them.  I also have some paper booties there if you
like using them, but it can be costly to keep stocking them up, plus the
fee to throw them away.

As per RPG, before you exit the hotlab please check yourself.  If the
cloth booties are clean of radiation, please put the them back to the box.
 I'll ask to get them wash every now and then.

 Thursday, November 21, 2024, 11:46: 2 Glovebox gloves were changed. The far right glove & the far left glove. 

No contamination was found on the sealing edges of the glove box. Both old gloves were placed in bags & placed in the alpha waste bin.

Work Permit: I2024-11-21-2

Note* Changing both inner gloves is recommended later. We had considered to do both however the O2 ppm spiked after the change of the first two. We were at 185 ppm & aim to not cross 200 ppm.

Additional info:

The remaining gloves were inspected and appeared in acceptable condition.  A regeneration was performed shortly after and the gas lines, pump lines were also inspected.  This will be considered as the inspection for the current inspection cycle.

The Ar glove box issues ( https://elog.triumf.ca/TIS/General/23 ) have been fixed.

Quoted from work permit: I2019-03-19-4

RPG checked the old SS lines. They were clear of contamination although still contained TCE. The TCE was cleaned out & removed.

The Ar glove box is connected properly to the nuclear ventilation as well as having the added filter / catch. The SS lines were replaced & valves cleaned. A large clog was found in the vent line and has been removed. Will now be able to test the regeneration function of the glove box.

-A regeneration should be performed monitored to test the lines for the glove box to be officially fixed.

The blockage was found on the exit of the Ar Glove Box. The blockage was held within a Swagelok check valve (P/N - B4CP2-1/3 - https://www.swagelok.com/en/catalog/Product/Detail?part=B-4CP2-1/3). It may have been installed intentionally, it may have been assumed to be a 1/4" brass pipe nipple. At any rate it was completely plugged and

did not allow for proper venting of the regeneration lines. Pictures of the blocked valve are included. The regeneration function is ready to be tested.

A regeneration of the Ar Glove box had been performed Monday, 04, Feb, 2019. At some point during the night of the 4/5, a leak of volatile materials burst out of the vent line inside the control box housing the fuses, solenoid valves, & electrical components. The volatile liquid, determined to likely contain Trichloroethylene, ate through the plug holding one of the 250 V 4A fuses. The plug then shorted to the glove box itself and the glove box main touch screen & controls completely shut off. The H2O & O2 monitors still worked, however we were unable to allow any Ar back into the box. A noticeable electrical / burning smell was found in the morning of the 5th and the cover removed. A highly irritating chemical smell was also found and respirators were then put to use.

A work permit (I2019-02-05-3) was opened for the cleanup & inspection of the fuses and electrical components. Darwin & I spent the afternoon of the 5th to cleanup the volatile liquid. It was determined that the glove box was temporarily ok as it was still maintaining a low oxygen atmosphere (below 200 ppm)

On the sixth we changed out the melted fuse plug and replaced the fuse however the Ar glove box did not respond in kind. 

Thursday, February 07, 2019, 08:00: Contacted Randy Boehm. He determined the lines were still alive, including the small control box and 4 fuse plugs. We changed two of the 10A fuses and cleaned the plugs. The touchscreen came back.

Thursday, February 07, 2019, 09:15: Contacted Darwin. Initially the Ar glove box did not purge and the solenoid valves did not respond, however 10A Fuse #F1 & 4A Fuse #F3 just needed to be seated properly. 

The glove box was able to be purged & made stable.

The source of the main volatile leak has not yet been determined completely (Thursday, February 07, 2019, 11:25) however it will be investigated this afternoon. 

In the meantime do not use the Ar Glove box 'Regeneration' function.

Friday, February 08, 2019: The source of the leak was determined to be the vent line leading out from the last solenoid in the control box and out to the regeneration purge /  vent outlet. It has a pin hole leak mid-line and a clear 'burst' from the fitting leading into the solenoid valve. Another noteworthy issue was found. The regeneration purge / vent outlet leads directly out into the hot lab atmosphere. During any regeneration, a small amount of TCE & material is released from the argon glove box.

A non-conformance is issued (NCR 12029) and a work permit plan is being setup. 

The line main vent line is to be replaced with lengths of 3/8" x 0.040" wt SS tubing and the regen purge/vent outlet re-linked to the nuclear ventilation. RPG has issued P100 Organic vapor / Acid gas cartridges for use in the repair.

Will update with the upcoming work permit*

Thursday, April 07, 2022, 12:00: While preparing to remove LaC, the roughing pump (1) stopped operating. It didn't appear to seize, just no longer powered up. Multiple outlets attempted. Vacuum group contacted & they brought us a replacement.

Thursday, April 07, 2022, 12:21: Pump was replaced. (Pump 2).

Friday, April 22, 2022, 11:30: The roughing pump failed (Pump 2) & shut-off. Appears to have seized. Oil?

Was replaced by Vacuum Group in the afternoon with 3rd pump.

Monday, April 25, 2022, 09:13: Roughing pump failed & shut-off. (Pump 3). The oil was completely drawn out of it & into the ventilation line (To EF14).

Fault: 14843

Friday, June 01, 2022, 12:00: RP changed with a new IDP15 roughing pump. Fixed. 

 Thursday, April 07, 2022, 11:55:

It was noticed on Wednesday that the glove box was not regulating pressure properly & the H2O sensor was reading (Very unstable) anywhere from 30 ppm to 0.25%. The box was isolated & checked for leaks. Unable to vent properly except manually.

One of the solenoid valves for venting the glove box fails to open. Will need replacement. The filter also appears to be saturated. Regeneration is required once the solenoid valve is replaced. Prior to replacing the valves, the LaC must be safely removed. This process is being initiated. (John W. & Darwin O.)

 Monday, April 15, 2024, 10:50: The old IDP15 RP was not pumping the antechamber down properly. An exchange IDP15 pump is loaned to us from vacuum group. Once the tip seals on it are replaced, we will swap it again.

Applicable work permit: I2024-04-12--2. Status: Returned. 

 On November 10th / 11th a site wide power outage occured. Once power was restored, the Ar glove box had intermittent issues with the solenoids & blower. The blower did not start & the solenoids often got stuck or ceased operating. 

Yesterday Randy B inspected the connections to see if they were receiving enough power. It was good from the main plug-in, through to the PLC, however was dead at fuse positions 3 & 4 on the rear panel. Both fuses were changed, but that did not help. We did some fidgeting in the back & the solenoid function returned. It was left overnight.

Thursday, November 30, 2023, 08:30: <- Approx. Initial check: Dropped a crumpled Kimwipe inside the glove box to check for air flow / blower function. It did not move. Blower was not functioning, but the solenoids did. De-energized the glove box completely. 

Removed the old corroded fuse holders, added a pair of modified new ones. Cleaned a couple of corroded critical connections. Installed the new fuses, re-plugged it back in. Function returned to normal. The Kimwipe was also moving, verifying the blower is again operational. 

Thursday, November 30, 2023, 09:51: Complete. 

All the fumehood pumps in the ISAC-I hot and cold labs got tripped off when the MCC-X was powered down (See ISAC WP#2011-03-30-5). No reaction process is done inside the  fumehoods, so the pumps are ok to be left off for now until the MCC-X work is done.
