|
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.

Friday, February 15, 2019, 12:05, David Wang, ITE, Maintenance, TM4, , ITE annual vacuum leak check.
|
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. |

Monday, February 11, 2019, 10:26, Isaac Earle, Safe Module Parking, Development, , , SMP shield box and vacuum vessel moved to Target Hall 6x
|
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 |

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, January 24, 2019, 10:34, David Wang, ITW, Maintenance, , , Changed 24VDC plugs of TP solenoid valves in ITW
|
| 3 damaged 24VDC plugs of TP solenoid valves are replaced. Inspected other plugs. All of them are in good condition now. |
|
Tuesday, January 22, 2019, 09:56, David Wang, ITW, Maintenance, TM2, , ITW water system maintenance.
|
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. |

Monday, January 21, 2019, 16:27, Isaac Earle, North Hot-Cell, Development, , , NHC in-cell camera wired to right side monitor
|
The NHC right side monitor has been wired to display the signal from the in-cell camera. This was tested using a snake camera on both of
the CPC-4 connectors.

Friday, January 18, 2019, 10:26, Isaac Earle, North Hot-Cell, Development, , , NHC sealing improvements and repeat of RH test for LED lights
|
The following NHC development work was completed under WP I2019-01-09-4:
Location of RH feature on operator level LED lighting updated to match IRH1800 Rev B design
Remote Handling test of the
LED fixtures was repeated using a 9' pole with hook attachment through the manipulator slave hatch from the Target Hall: both LED fixtures were removed |

Friday, January 11, 2019, 13:59, Isaac Earle, Safe Module Parking, Development, , , SMP motor selection decision
|
SMP drivetrain design work is currently underway. Alejandro has selected a suitable 1200:1 reducer which will give a vessel rotation speed of 0.21rpm
with a 1725rpm motor (deemed sufficiently close to the SHC rotation speed of 0.17rpm). The reducer however is only rated for 0.33hp, and Allon's
analysis recommended we use a motor of at least 0.4hp |

|
The spent target in the south hot cell has been moved to the spent target vault. It was placed in pail 204 and placed in spot 6B. The pail is made
of thicker steel and thus will not need to be repackaged later. The ISAC spent target vault is full there is no more room for any more targets. |
