ITW water system maintenance is done. All working paddle wheels and coils are replaced. ITW water system polyurethane tubes are replaced as well. Two
3/8" leak small valves on return lines are replaced. 85 liters of tritium water are transferred from storage tank to B2 level holding tank. LALC water
are refilled into S-tank. Restarted pump and checked system. Everything works fine now. No water leak has been found so far. |

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. |

|
On February 8th the SMP shield box (IRH1675) and the vacuum vessel (IRH1806) were both raised from a horizontal to vertical orientation in
the ISAC-1 Experimental Hall. Hamilton "Mini-Mite" S-MM2-43FS caster wheels were then installed on the base of the shield box and it was
lowered down the hatch to the B2 level. The vacuum vessel was then lowered into the shield box, supported by the rollers, as designed. The |

|
Helium pressure test on all water lines: 70psi , 3 minutes. HS has a quick response to 9Xe-9atm.cc/sec for 20 seconds. No response on other lines. All
water lines are good. Air to vacuum leack check on ITE and TM4: TM4 IG1 / Steers side panel has a low E-6 atm.cc/sec leak. The o-ring need to be
changed when TM4 is located at TCS. All other air to vacuum seals are good on both primary and secondary vacuum vessel. |

The ITE water system maintenance job is done. Changed all paddle wheels and coils on ITE flow sensors. All using water poly-tubes in ITE are replaced
. Started high active water pump, and checked ITE water signals. They are good. No leak has been found on replaced tubes and related fittings.

|
Dragan Mitrovic, TRIUMF structural engineer, was consulted earlier this week regarding seismic requirements for the SMP assembly. Installation
location, overall dimensions, total weight, and the center of mass for assembly IRH1670 were provided to him by e-mail. On Feb 20th he communicated
verbally that he had analyzed the assembly for seismic loads, and concluded that this equipment does not require anchoring or any other form of seismic |

|
TM4 optics tray was installed onto the old TM2 source tray yesterday and tray filled with non-active metal scrap. Tray inserted into transfer frame 95%
yesterday. During insertion the ball nut of the transfer jig became unfastened from its drive plate. This will have to be fixed before the jig can be used
reliably again however we were able to finish the job...the transfer jig is 20 years old now so it is not entirely suprising that it needs some attention. |

|
Transfer fixture has been remotely disassembled to the point where the ball nut lock plate assembly can be inserted into the tool port and the plate
replaced by hand in the tool port without having to enter the hot cell. Straight head screws will be replaced with SHCS to facilitate easier re-assembly
and future disassembly. |
