Entry  Friday, June 17, 2011, 11:58, John Wong, UCx (flakes), LP-SIS, , , , , Problems/Solutions, Making UC2 flakes (stock# 2011_A & _B) 8x

Fri Jun 17 10:28:47 2011

First batch of UO2/C mixture of carbonization (Stock# 2011_A):   

UO2 used = 50.120g (left overs + container = 411.23g)

C(grv) used = 10.653g (or 21.25% w/w)

Mass of organics = 4.842g (or 9.66% w/w) 

Mass of dried cast = 47.420g 

Waste collected in jar = 18.195g (including UO2, C and Org) 

Waste accountable for UO2 = 12.57g

The carbonization process started from May 26 to June 4 (9 days).  

See attachment #1 and #2 for the striptools during the UO2/C carbonization

Total Mass UC2 flakes = 35.310g 


 Fri Jun 17 11:56:15 2011

Attempted to make the second batch of UO2/C mixture of carbonization on June 13, but it failed.  The milling jar gasket seal partially came out during the high speed milling.  As a result, the UO2/C mixture squirted out and contaminated the planetary mill (See attachment #3 & #4).  RPG and all other groups were informed.  The planetary mill and the lab were properly cleaned up (see attachment #5), no activities were found after the cleaning.  Attachments #6, #7, #8 are some of the discussion about the UO2 spill.  

All the UO2 taken out from the container (50.23g) is accountable for waste.  

 


 June 28, 2011 - Re-making 2nd batch of UO2/C mixture was successful.  

Stock#2011_B:

UO2 used = 50.29g

C(grv) used = 10.0g 

Mass of Organics = 4.84g 

Mass of Dried green = 71.96g (the cast was let dry over night <24hrs due to time restriction.  It might not be completely dried as a result of such heavy mass remained.  However, the UO2 waste was very minimum, <5.0g) 

Total Mass UC2 flakes = 56.853g

 After the test stand, deposited material was found on the Extraction Electrode. A sample of the material was taken for later analysis. The electrode was cleaned with methanol. See attachment for photos.

Entry  Wednesday, August 01, 2012, 09:37, Pierre Bricault, ITE-TM4-UO#3, LP-FEBIAD, ITE, TM4, , , Problems/Solutions, Short has developed while lowering the cathode heater 

 On tuesday July we lower the cathode heater to swap the anode-cathode bias. While lowering the cathode heater a short on the anode developed. 

The polarity swap was not possible because the target/tube assembly has also a short to common. 

We return the configuration has it was and we added two 100 Ohms: 5 W resistor between the common and the heaters to prevent current to flow back to the common. 

The anode short disappear during the cathode and target heating. 

Entry  Tuesday, June 21, 2022, 15:34, Matthew Gareau, SiC#42, SiC#43, , , TM2, , , Problems/Solutions, Multipin guide pin issues 

 While removing the SiC#42 it became apparent that the multipin guide pin had become loose again and was not allowing the target to dismount from the module.

The multipin shoulder bolts were removed and then the multipin was able to be pried off.

However the NHC manipulator were not able to reach the guide pin to remove it, which would be required before the SiC#43 could be installed.

The target module was then moved to the SHC where the guide pin could be removed and the installation of SiC#43 took place, along with the transfer of the parasitic attachment onto the SiC#43.

This problem seems to suggest that the multipin could use some redesign to ensure smoother target exchanges.

This afternoon, Darwin prepared in the hot lab fume hood the two UO2 slurries to be cut into P2N target discs. Later, I took over cutting both slurries. A total of 49 annular discs were cut and loaded into the P2N graphite container.

The discs thickness was measured by stacking 5 discs on each other, and measuring their thickness in two points.

#discs = 49

Average disc thickness = 0.453mm

Empty cartridge weight = 9.42 g

Full cartridge weight = 39.86 g

UO2+C weight = 30.44 g

The unused material plus the cutting scrap were left in a zip lock bag on a shelf in the right hand side of the fume hood. The center scraps and the loaded target were placed in a plastic tray on the top shelf. The used tools and scales were left on the right of the working area, the napkins on the bottom were put into the garbage bag (inside the fume hood) and replaced, while the only napkin left is the one with the target information (recorded in attached picture).

UCx#5 target description, see attachment#1

The target is currently undergoing the final conditioning in the Evaporator #1. 


 Wednesday, December 05, 2012, 15:46

This target was broken right before the end of the final run.  The target was inspected today inside the Hotcell and the pictures can be found here: http://documents.triumf.ca/docushare/dsweb/View/Collection-9357

Looks like the protective layer (TaC coating) was worn out over the course of the run time. 

We need to improve the target coating so this can be prevented in the future.

More info about this later...
