|
The North Hot Cell inlet ducting assembly was installed today in the target hall at the north end of the NHC roof block. A small section of the
perforated aluminum sheet on the TCS cage had to be trimmed for the assembly to fit (see IMG_0214). At each end of the assembly it was fastened to
the roof structure using a 1/4"-20 tapped hole in the steel roof, and a 1/4"-20 anchor in the north wall of the target hall. The base flange |

|
Gordon crane technician Peter came in today and checked TH crane. Maico and I were there with him. What he found is that brake gap on both side of
main hoist decreased after months of using. The solution is to lock the automatic self adjustment system so the gap will be fixed there. Each year
during annual inspection, they will adjust the gap manually. After he locked both side of device, I tested the crane up and down couple of times. The |

|
The North Hot Cell module support flange (IRH1152D) was installed on June 21, 2017 using 1/8" rubber sheet as a sealing gasket. The
rubber was glued at the seams with Loctite 495 instant adhesive. Cameras with all required wiring and connectors were installed on the mounting bars
(IGN0325D) and then aligned to provide the same view as at other module installation locations in the target hall. A cable with 5 video signals, |

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. |

|
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. |

|
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 |

|
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 |

|
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 |
