|
I disconnected TM1 in ITW yesterday morning.The general radioactive level in ITW over the TM top (300mm) is about 350 usv/hr. contacting level on TP1
and TP2 are 1.0-1.2 msv/hr. I took 0.22 msv dose .The module is moved to
south hot cell later and a shielding plug is put back to ITW. Everything is fine. |

Monday, June 25, 2012, 14:39, David Wang, ITW, Standard Operation, , , I moved 5 shielding blocks from ITE to ITW,
|
and set up ventilation for ITW. ITW is ready for taking proton beam now. All water interlock checks for ITW are done. The ITW water signals strength
and frequency had been checked from electrical room, and everything is good. |

Tuesday, June 26, 2012, 14:10, David Wang, South Hot-Cell, Repair, TM3, , TM3 heat shield and window circuits leak check is done.
|
Chad and i did a leak check on TM3 heat shield and window circuits.Both circuits are pumped easily down to the bottom leak rate and base pressure on
the leak detector. There are two VCR caps on heat shield circuit. Chad sprayed helium on both of them ( tested individually,2 seconds every time
) . There is no response on leakdetecor during 45 seconds waiting time. On window circuit there are 2 VCR joints. Chad sprayed helim on these joints(2seconds |

|
In the AM today David and I used the crane to raise the ground plate sheet metal into place. This afternoon when I attempted to return the crane to its
usual place I discovered that the crane no longer worked. Upon further inspection it appears that the PLC has lost power. I will follow up on this Monday
morning. The crane is not supporting any load at this point. |

|
Today (Wednesday July 18th) at around 4:15 pm I was taking a small tour group from VECC into the Target Hall. In the process of discussing the mechanical
design of the Target Modules and South Hot Cell turntable I inadvertently lifted the Aluminum Hatch Cover of the Hot Cell about 2 inches in an effort
to explain something. This tripped the ventilation alarm before I realized what I was doing. I evacuated the visitors from the Target Hall, checked |

Entered south hot cell Wednesday and replaced the pre-filter air filter as well as the front two light bulbs. Also removed two bags of compressible garbage,
one bag of metal, and of course the bagged air filter (as Joe M. expressed as interest in havung it).
Inital checks found approximately 4000 cpm on the cell side of the temporary Al. panel used during the cell entry, 2000 cpm on the tacky mats layed |

The F-308 have been cleaned and serviced. There were three F-308's that came back with some contamination.#13, #15 and #19 were found to have contamination.
They were decontaminated. All of the loose contamination was removed. There is still some fixed contamination. The levels of contamination are low enough
to still be used for shipping spent targets. They have been moved to the north hot cell area and are ready for to be filled with spent targets. |
