|
TM1 with Ta #37 target was moved from ITW to the south hot cell. The rotation of TM1 may have been off slightly during the final removal from ITW
but it was minimal. Entry into the south hot cell went with out incident. This was my first time moving the module without the presence of Travis Cave. |

Thursday, July 09, 2015, 14:02, David Wang, Conditioning Station, Development, TM1, , TM1 is pumping down at CS
|
TM1 and CS vacuum system are connected. All turbo-pumps are started. The new TP1S works fine also. The pumping down looks good so far. During the
TM1 and CS roughing down time, Joe .M noticed a Rn-220 level surge up in TH . Then,the Rn220 level slowly dropped back. Anders suspected this Rn-220
surging is related to the TM1 roughing down at CS. We decided we will stop the pumps , vent the CS , and roughing again tomorrow. During the same |

|
Chad and i did a leak check on TM1heat shield with UCx target on.The circuit are pumped down to the bottom leak rate and base pressure is 3xE-3
torr 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 ) . The test repeated 1 time.There is no response on leak detector during 45 seconds waiting time on both time.Chad flushed helium around the |

|
Chad and i did a leak check on TM1(Lp-TiC) heat shield water circuit at south hot cell. There is no leak had been found on it. The circuit is leak
tight at present. I will do helium pressure check on this circuit at conditioning station once the vacuum is good enough. |

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. |

I removed 5 shielding blocks from ITW to block storage area, and disconnected TM1 in ITW. After UCx run, the radioactive level around the turbo
pumps and primary vacuum lines are pretty high. This affect the general field inside the ITW pit around working area.i took 15 minuts to finish the job
and i got 0.1msvr dose. the general field around my working area is about 350 usv/h. |
