Thursday, March 08, 2018, 14:10, David Wang, ITW, Maintenance, , , Two small water leak has been found in ITW.
|
Two small water leaks have been found on ITW High active water system. One is from an unused 1/4" copper valve stem. another is on supply 1.5"
supply line valve body top sealing. Both of them are seeping water from seal. 1/4" copper valve will be replaced with a new one. 1.5" supply
line valve will be replaced by an old valve with all new seals. I have all spare parts in hand. At present, water supply to ITW are stooped to |

|
HALCW resin can flow meter replacement is done. Less that 100 mL water was drained to a small tray during the job. RPG checked the water. Less than 20
counts. Water are dumped the high active sump. The HALCW MP1 is started. No leak on new gauges and fittings. Old gauge is labeled , bagged,
and stored in TH. |

|
I can not see oil in sight window of the primary pump during visual inspection. The aluminum tray underneath the pump is filled with oil. The performance
on this pump start to drop by watching ITH CG4 reading. A fault report with suggestion is issued to vacuum group. Everything on secondary pump looks
fine. |

|
The spent target assay was aborted today after the first target was finished due to the very old computer that controls the camera and the vault
door effectively died. The vault door had to be closed using the emergency door closing winch which worked so it passed that test. |

Wednesday, February 28, 2018, 14:47, David Wang, ITE, Standard Operation, , , leak check ITE primary and secondary vacuum vessel.
|
2018-02-27: Anders and I finished leak check on ITE primary and second vacuum vessel seals. LD connected to ITE BV2 valves between. LD, Base Leak rate
1.2 xE-9atm.cc/sec, base pressure 0.0XE-4torr. There is a leak has been found on TM4 service cap KF25 blank off. The o-ring on the blank off will be changed
later. It is an easy fix . Other seals are good. The big T tank seal on secondary vessel is leak checked as well. It is still fine. Helium pressure |

|
The old resin tank has been stored in silo since last year March. Without crane the tank up, We use the pole monitor measured the field around
the bottom of the tank in silo. The average contact field on the bottom is about 4.0msv/hr. @0.5meter , the field is about 900usv/hr. It is still
too hot to remove it. |
