|
John Chow and I installed new TCS HV cable and feed through with their mounting panel back to TCS Faraday cage this Tuesday. ECO-4269 has been issued
for the new cable feed through and mounting panel. |
Wednesday, July 05, 2017, 15:36, Isaac Earle, North Hot-Cell, Development, , , NHC and SHC nuclear ventilation flow sensors installed 
|
Installation of new flow sensors and transmitters for the NHC and SHC duct lines was completed in the target hall today. The sensors are
Dwyer DS-300-8 in-line sensors for 8" pipe; The transmitters are Dwyer MS0121 magnesense differential transmitters with 4-20mA output. The transmitters
will be wired to the new PLC control system when the upgrade is done. |

Thursday, July 06, 2017, 14:23, Isaac Earle, North Hot-Cell, Repair, , , Slave side Z motion tape snapped on NHC right side manipulator
|
The NHC right side manipulator was evaluated today to check if operation was normal through all ranges of motion. The manipulator was first moved
through usual motions without the electric motion drives: the feel was fairly normal, a sound could be heard from the master side Z motion tapes rubbing
on the sides of the pulleys, this problem had been identified a few weeks ago however it was significantly reduced since the master side upper and lower |

Monday, July 10, 2017, 09:09, Dan McDonald, North Hot-Cell, Repair, , , manipulator cart repair
|
A hydraulic leak was found on the manipulator install and repair cart, upon further investigation the cause was a faulty cylinder. Once the
cylinder was removed and disassembled the inner bore was found to be scored beyond repair. Another point of interest was that the rod was painted to the
point that when retracted it compromised the rod seal causing the cylinder to leak. attached are photos outlining the issues. new cylinders are being sourced |

|
Earlier in the day it was noted that the rotate function of the crane had creased operation. After David has finished the block moves. Don and
I checked the Crane's control unit in the ISAC crane control room and found the breaker tripped for the rotation. The breaker was reset and the crane's
rotation is now operational. If this occurs in the future only Travis Cave, Don Jackson or a TRIUMF Electrician are allowed in that control box as it is |

Wednesday, August 02, 2017, 15:13, David Wang, South Hot-Cell, Standard Operation, TM2, , SHC, TM2 leak check on HS line.
|
HS line is leak checked at SHC this afternoon by helium spay. Leak detector base LR 0.0 XE-9atm.cc/sec. Base pressure 0.0Xe-4 torr. No leak has
been found. This line will be helium pressured at TCS. It had a 1.7XE-7 atm.cc/sec leak rate on 70 psi helium at TCS during last two
target checks. |

|
The NHC drain line was tested by pouring approximately 10 gallons of water through the drain grate at the base of the NHC partition wall. Water
was seen a few minutes later pouring into the sump labeled "ACTIVE SUMP" from the light coloured pipe on the west side of the inside of the sump.
Rob Walker had previously said that the hot cells drain into the sump next to this one which is labeled "SANITARY SUMP", which appears |

Tuesday, August 15, 2017, 12:10, Isaac Earle, North Hot-Cell, Development, , , ISAC Active Sump low water level measured
|
The ISAC active sump in the Active Service Room (#002 on B2 level) was pumped out yesterday using the standard procedure (Section 5.5.2 of the ISAC Operators'
Manual, V1.0). The procedure makes use of the auto stop feature of the pump-out system which stops when a low level float switch is triggered. The
water level was measured after pumping stopped, and was found to be approximately 21" above the base of the sump. A new section of pipe will |
