Your login names and temporary passwords are your first and last name (no spacing & all low cases, eg. Maico's user and password: maicodallavalla).  Once you're logged in, please change your password. 

I have created a few more elogs for the Remote Handling group:  RH-Cyclotron, RH-Conditioning Station, RH-Yield Station.  All new elogs entries come with the default attributes, "TYPE" and "Category".  These attributes and the dropdown options can be added and changed.  See "Evaporator_1" logbook how I have created 4 attributes: Target, Number, Source, Status. There are also many other functions, see the attachment for a few examples. Try using the elog; let me know how you would like to change it to work better for you and the group, and I'll do my best.

 If you have any question, please feel free to ask.  

TIS-Elog Administrator,

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...

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.

 Monday, January 13, 2020, 10:30: Leak noted in HC area by Chad to ISAC Ops.

Monday, January 13, 2020, 13:32: The water leak was found to be coming from the sinks in the ISAC B1 Cold Lab. Target cleaning was occurring at the time as well. Soap / detergent smell was noted in the water that had dripped down to the area in front of the South Hot Cell in ISAC B2.

Rob Shanks entered a fault report. 

Running the main cold lab tap or the fume hood tap did not yield a leak, however, dumping a large quantity of water into the 2 main sinks in the ISAC B1 cold lab causes the leak to become apparent. It's likely the large volume of water causes a brief back flow in the pipe in ISAC B2 which then leaks until the flow recovers.

The pipe joint with the leak has been circled in the attached photo. 

Anders & I both witnessed the leak to confirm the source.

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.)

Fri May 13 11:55:37 2011:  The contain in the uranium waste container was removed and transferred into a beaker and sealed.  The total waste mass = 12.59g, over 100K CPM.  The container is double bagged and will be removed from the Hotlab.

Re-Cap:  On June 13, 2011, the milling jar gasket seal partially came out during the high speed milling (400RPM), and the ball mill was contaminated with UO2/C mixture (See TIS/Target Production message ID#9, UCx#2, for more details).

Today, the ball mill was successfully re-commissioned.  RPG's helped to take some air samples during the commissioning, and nothing above the background was detected.  The cold-lab is now re-open back; no booties are required.  The commissioning plan and commissioning report are available on DocuShare. 

 Tuesday, July 19, 2011, 16:22:  The planetary ball mill was in the coldlab, and now it has moved to the hot lab for the purpose of processing UCx targets.  The ball mill is installed in front of the fumehood and near by the alpha filters.  The legs are secured in the metal rings so the machine will not move away during milling.  (see attachment).

Over the long weekend ~1000psi was used up, indicating a leak somewhere in the glove box. 

Tests over the past few days showed ~150psi leaked in 48hrs.

Tested both transfer chambers for leaks, both chambers held pressure fine/ no leaks detected.

Checked all the gloves for leaks and found a ~1mm size hole on the index finger of the right glove closest to the control box.

See photos attached.

Has been sealed off temporarily with duck tape.

Will replace glove after the weekend.

 Tuesday, April 10, 2018, 06:45: Work permit for glove(s) replacement, I2018-04-09--4 submitted yesterday. Current status: Pending. -Aaron S.

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..

On Friday July 31 a regeneration of the glovebox was started.

Initial 02 = 130 ppm

Initial H20= 1.9 ppm

The Argon gas level was 1200 psi

The regeneration was finished on August 01, 2020. 

The 02 level (not accurate as stated in the manual) was p 137 ppm.

The H20 level was 8.9 ppm and not considered accurate as the system needs time to reach equilibrium.

The final 02 level was 7.0 ppm and recorded on August 05, 2020.  The final moisture levels were recorded to be 1.9 ppm.

The regeneration was successful and it was concluded that the catalyst is active enough so that it does not need to be replaced.

02 = 6.75 ppm

H20 = 1.9 ppm

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. 

ISAC-1 B1 Hot Lab actinide mass balance calibration was carried out on April 18, 2023, at 10:40 a.m. with an accuracy of 0.01%.

On Monday June 19th, the Glove box was inspected.  Gas lines, solenoids, pump, argon usage, state of gloves and gas levels were checked. 

The only note is that we have one pair of spare gloves for the glove box and we don't have a spare for the Evap1 glove box.  We will try to order spare for the Evap1 glove box.

 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.

This is a belated entry.  The inspection was performed on December 19, 2023.  A leak on one of the lines from the regulator (regeneration gas) was fixed. No other issues were found. 

All lines, pump, blower, were found in working condition. 

A regeneration can proceed.
