Thursday, January 31, 2019, 14:16, Isaac Earle, North Hot-Cell, Development, , , NHC grounding approval
|
Franco Mammarella was consulted regarding electrical grounding of the NHC design (RS103 of Document-131915). After discussing the design,
and having grounding inspected by Randy Boehm, Franco approved the design and advised that the grounding system should be inspected periodically.
This task has been added to the Remote Handling inspection index on an annual schedule. A PDF copy of the e-mail correspondence with Franco is attached. |

Thursday, March 04, 2021, 16:30, Isaac Earle, North Hot-Cell, Development, , , NHC gas delivery lines leak checked
|
The North Hot Cell gas delivery lines (labeled 1, 2, and 3 on the hot and cold side panels) were leak checked today. 5psi helium gas was
applied to each line in turn with the appropriate solenoid valve opened and a Staubli connector with plastic tubing and the leak check wand attached to
the matching connector inside the cell. The end of the wand was sealed using tape. The Agilent G8601 leak detector was used on "sniffing" |

Tuesday, February 28, 2017, 17:51, Isaac Earle, North Hot-Cell, Development, , , NHC flanged ducting connection sealed
|
The North Hot Cell ducting (IRH1617) has been sealed with a bead of Sikaflex 1a polyurethane construction sealant where the flanged connection
bolts to the NHC/TCS partition wall. When this sealant shows signs of aging it may be cut away and re-applied without unbolting the flange.

|
The fields in the NHC after removal of Ferran's graphite sample is 238 uSv/h. This again seems to emanate for the items in the 5 gal pail...the copper
tubing from the beam window or, as I mentioned in my previous elog, the peek samples. I did ask about removing these during the graphite sample removal
but was told they were not "hot". |

Tuesday, April 18, 2023, 07:28, chad fisher, North Hot-Cell, Maintenance, , , NHC entry summary
|
NHC was entered on April 17, 2023 for inspection and maintenance. Summary :
Compressible and non-compressible waste was loaded into a 55 gal drum and removed from the NHC. This same drum will be inserted into the SHC at
a later date to be sorted, compressible waste compressed, and drum filled more. |

Tuesday, January 17, 2017, 13:45, Isaac Earle, North Hot-Cell, Development, , , NHC ducting installed
|
The new ducting section connecting the existing duct termination in the TCS space to the NHC partition wall has been installed by Smith Sheet Metal
contractors. The installation drawing is IRH1618. There was not enough clearance between the duct pipe and the TCS vessel to butt weld the
new ductwork as originally intended. Instead a flange was welded to the existing pipe and also to the new section and the two were bolted together. |

Wednesday, August 09, 2017, 16:39, Isaac Earle, North Hot-Cell, Development, , , NHC drain line into sump identified
|
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 |

Wednesday, August 01, 2018, 09:47, Isaac Earle, North Hot-Cell, Development, , , NHC diagnostic signals and control panel tested
|
On July 30th the NHC diagnostic signals were tested:
- 9 pin CPC: a shorting plug was installed on the hot side - continuity check results were as expected
- 4 pin CPCs: snake camera installed in both hot side connectors with portable monitor on cold side - both connectors worked as expected |

|
Installation of the diagnostic connections between the NHC hot and cold sides has been completed. The cable bundle was prepared by Travis Cave
in the electronics workshop with connectors attached at one end only. Metal fish tape was first ran through the conduit from the cold side to hot
side, the non-terminated end of the cable bundle was attached to the fish tape inside the cell, cable pulling lubricant was applied, then the cable bundle |

Thursday, November 22, 2018, 14:38, Isaac Earle, North Hot-Cell, Development, , , NHC design approved by High Voltage Engineer
|
To satisfy RS 101 from the NHC requirements specification (Document-131915) Tomislav Hurskovec was consulted regarding high voltage safety. After
a verbal discussion on various aspects of the NHC design he confirmed that the design satisfies high voltage safety concerns.
A copy of his confirmation e-mail is attached in PDF format. |

Friday, January 04, 2019, 14:38, Isaac Earle, North Hot-Cell, Development, , , NHC cameras tested
|
The NHC module support flange cameras (4 total) as well as the NHCSA camera were tested today and confirmed to be working properly. All cameras
were angled and focused properly, and displaying clearly on the monitors in the ISAC RH Control Room. Photos of the control room monitors are attached

|
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. |

|
Testing was completed today on the NHC air and gas supply lines. For each line a Staubli plug was installed on the fitting inside the hot cell,
the line was charged with compressed air (50psi for gas lines #1, #2, and #3; 100psi for the air lines #4 and #5). All connections inside and
outside the cell were checked for leaks using Snoop including connections for the solenoid valves. No leaks were found. Correct operation of |

|
Measurements were taken today of the NHC north/south wall gap at the location where the NHC/TCS partition wall will be installed (43.375"
from the NHC west wall). A HILTI PD40 laser range meter was used for the measurements. They were taken at 10", 34", 62", 90",
118", and 142" from the floor which matches the top of each cross-beam. The results are below: |

|
The sheet metal panel covering the NHC/SHC feedthrough port was removed today using a slide-hammer to pull out the concrete anchors (this oversized panel
would have interfered with the NHC partition wall). 50cpm was found on the inside of the panel, 100cpm on the NHC side lip of the feedthrough, and
350cpm on the face of the shielding bricks in the feedthrough. Various dimensional measurements of the feedthrough were taken which will be added |

Tuesday, November 22, 2022, 14:53, Carla Babcock, North Hot-Cell, Maintenance, TM4, , Multipin connector alignment pin on TM4 module loose
|
The pin on TM4 has become loose again, making it very difficult to remove the multipin connector with the last target, C#4. For the installation of the
next target, UCx#41, we will drill out the hole on the target side bracket so that it doesn't contact the multipin pin. Will try to remove this pin by
force in January, or if needed change out the whole multipin bracket. |
