Thursday, December 21, 2023, 09:36. ITE multipin wires 12-13-14-15 were rewired from the RF driver box to a TC datalogger inside the HV cage. A webcam was also installed to monitor the TC values during operation. This is only a temporary setup to be upgraded during shutdown.

 Thursday, March 21, 2024, 11:33 Three channels are available now for thermocouple readouts from the Target multipin. Wiring from the PLC modules to the connection terminal blocks and labeling done.

Entry  Monday, November 20, 2023, 12:28, Eric Lahe, South Hot-Cell, Maintenance, , , Light Bulb Replacement - South Hot Cell roof lights 

 3 light bulbs replaced in the ISAC South Hot Cell - North West light, South west light, and South East light bulbs. Northeast light currently still working.

 

The South East light is not working after bulb replacement. This bulb was tested using the wires from the Northeast light station and the bulb is working properly. Electrical services is being contacted to troubleshoot the cable issues.

ISAC Storage Vault Door Re-alignment (April-May 2024) 

Issue

  • Rollers gouging and marking on roller supports, testing shows door shifts at least 185 thou on structural beam when fully open vs. fully closed
  • door misaligned: 1/4" laterally, slight rotation (~1/16" difference across closed door gap).

 

Repair

  • Moved left structural beam (facing front of door) inward 1/4" at post.
  • Loosened drive system to shift door over via crane to average laterally (1/8" shift) towards center,
  • Attempted to fix door rotation with crane, door would not settle down perfectly flush, but got slight improvement 
  • Adjusted limit switches for fully open and closed (due to the adjustments made previously, needed to realign limit switches) - adjusted flag for final close back by ~1/4"; adjusted limit switch at back of vault forward ~1/4" 

 

Verification 

  • Unloaded vault door actuation tested multiple times with no issues, door returned to same position every cycle, no interferences during travel
  • Vault Door actuation tested with trays 4 and 6 engaged, no issues
  • All pails accessible when open
  • Tested open and closed limit switches: the open limit switches are working properly; the closing soft and hard limit switches are slightly close together, causing the door to just "bump" the vault when closing, The scale of this is OK for current operation, will be adjusted when the ISAC Target Hall Controls Overhaul is done
  • Tested and reset Emergency override mechanism - works properly

 

Outstanding Tasks

  • Will paint marks on structural supports to track if problem reoccurs - update ELog when complete 

 

System State: Operational

Entry  Thursday, September 01, 2011, 09:11, Don Jackson, ITW, Standard Operation, TM1, UCx#2, Argon Venting West Station 

West target station is setup to use argon for tank venting.  There is 1200 PSI remaining on argon bottle in electrical room.  That is sufficent for venting west target station to atmosphere twice.  ISAC Operations has been previousily contacted and their procedures for venting remain the same except that they can not rely on ITW:CG4S to determine when at atmospheric pressure.  I have asked them to contact me if an unscheduled vent is required.

Entry  Friday, June 08, 2012, 15:00, Don Jackson, South Hot-Cell, Standard Operation, TM1, Nb#6, Electrical Check Nb#6 at end of run Nb#6_End_of_Run.JPG

Megger check values were low but still within operational range.

Entry  Friday, June 08, 2012, 15:03, Don Jackson, South Hot-Cell, Standard Operation, TM1, Ta38, Electrical Check on new Ta38 at hot cell Ta38_New_Target.JPG

Megger checks were exceptionally high (good).  Readings taken less than 2 hours after reading low values from end of run on Nb#6.  Tests on Ta38 will be repeated at conditioning station later.

Entry  Tuesday, December 19, 2017, 10:40, Don Jackson, Crane, Maintenance, , , Crane Power during winter break 

 The power to the crane and controls were turned off using the power switch in the Crane Control room.  The main disconnect switch in the target hall was not touched.

All site power will be off for a period of time during the Christmas break and this removes the crane from any issues when power is restored.
