Attached please find the UCx#20 target description.

UCx#2 Spec:

Target wrapped with 3 Ta-heat shields

Target came out from the glovebox and transported to the cold lab for assembly.  During the assembly, one of the screw-heads for the heat-shield broke (see attachment#1: broken_screwhead). 

The target was leak checked and fine. 

Target is going back to the glovebox to be kept under Ar until RH is ready (see attachment #2: UCx#2).

UCx#2 run was finished last week.  

Target was moved from ITW to south hot cell, and stored in a bucket under argon feed.

Attached please find the UCx#13 target description.   

Note:  Target container was coated/sintered with TaC twice.  Would like to see if this will improve the life-span of the target.

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

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
