Travis Cave | Spent Target Vault | Standard Operation | | UO#3 | Spent target move |
The spent UO#3 was moved from the south hot cell to the storage vault. It was in pail 98 and placed in spot 1A of the vault, the field measured upon removal from the hot cell were 42mSv/hr. See attached PDF for vault details. |

David Wang | Conditioning Station | Standard Operation | TM4 | NiO #1 | TM4 NiO #1 target heat shield helium pressure check is done. |
leak detector pumped down to 0.0xE-9 atm.cc/sec, and 0.0xE-4 torr. All high vacuum gauge readings at CS and TM4 are at low -6 range from 2.2xE-6torr to 4.2x E-6 torr. Applied 80 psi helium to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit is leak tight. |

Travis Cave | Conditioning Station | Standard Operation | TM4 | NiO#1 | Electrical check |
See attached PDF for details. 60kV Common to the target is low at 343k but I've been told will work. Test will be done again on Friday after it has sat a few days under vacuum. |

David Wang | South Hot-Cell | Standard Operation | TM4 | NiO #1 | TM4 heat shield circuit leak check with NiO#1 target |
Chad and i did a leak check on TM4 heat shield circuit with new NiO#1 target installed. It took about 40 mins(much longer than usual) to pump down the circuit to leak rate 0.6x E-9atm.cc/sec and 0.0x E-4 torr o leak detector.
All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak tight.Chad sprayed helium on each VCR joints for 2 seconds every time. During 1min waiting time, there is no any response on leak detector. Chad repeated same test again for double checking and we got same result. Chad finally flushed the helium around the target heat shield for 10 seconds.we waited for 1minute and found no response on the leak detector. The heat shield circuit is leak tight at this stage. I will do a helium pressure test on this circuit when TM4 is in CS and under vacuum. |

chad fisher | South Hot-Cell | Maintenance | | | Hot Cell Maitenance |
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 out beside the work area but nothing on the floor under the plastic that had been layed down for the job.

I replaced ITW TP4S today as we scheduled. The working area is swiped and air sampled .Everything is fine.
The Series # of the old pump is 200927, and the new one is 600080. The E-fault 6081 which is related to the job will be closed. |

David Wang | Conditioning Station | Standard Operation | TM1 | UCx | TM1 UCx target heat shield helium pressure check is done. |
Connected leak detector to TM1 and CS vacuum system. The vacuum readings on TM1 and CS:PNG4 3.6 xE-6 Torr, IG1 1.1xE-6torr, IG4(diagnostic box) 3.4xE-6 Torr. Leak detector base pressure:0.0xE-4 torr, base leak rate: 0.0xE-9 atm.cc/sec. Applied 80 psi helium to heat shield circuit for 4 mins . There is no response on leak detector. The heat shield circuit is leak tight. |
