Thursday, February 09, 2017, 14:07, Isaac Earle, North Hot-Cell, Development, , , North Hot Cell Shielding Window Gaskets Changed 23x
|
The North Hot Cell shielding window gaskets have been changed and the window has been filled with new oil. Although there was no noticeable
oil leaks before starting the job, the gaskets had not been changed since initial installation approximately 15 years ago, so they were done now as part
of construction of the new cell. The work took place between January 26 – Feb 8, 2017 following the attached PDF “Full procedure |

Thursday, February 09, 2017, 09:24, David Wang, Conditioning Station, Development, , , Target module window cooling lines at TCS.
|
Target module window cooling lines at TCS has been modified to use spare 2 channel in TCS: WFB1. The old cooling lines used a spare channel in
TCS WFB2(HVC channel) are removed and capped. After change, TCS window cooling lines will be interlocked with heaters. The test run on new lines are good.
No leak on all fittings, and signals on flow and temperature are good. Control people will be noticed on this change for their following up |

Tuesday, February 07, 2017, 15:57, Isaac Earle, North Hot-Cell, Development, , , Ventilation Ducting Gasket Installed
|
| Lead gasket IRH1633 was installed today according to assembly drawing IRH1618 Rev B. |
|
Tuesday, February 07, 2017, 10:34, David Wang, ITW, Maintenance, , , ITW clean up
|
ITW has been cleaned up today. All station are vacuum cleaned. I wiped all HV cover and HV area including conductors and insulators. The black
foams which are used to wrap around TP back up line are degrading now. I removed most of these foams. Also, Some obsolete water lines are moved
our of station. All waste are bagged . they will be surveyed and stored(or disposed) according to radio-active level. |

Wednesday, February 01, 2017, 12:23, David Wang, ITE, Standard Operation, TM2, , TM2 has been connected in ITE.
|
TM2 has been connected in ITE. The SST window water lines in ITE can not be connected properly to TM2. The water line connector on TM2 window is 90 degree
CCW installed in direction comparing to TM4.This caused the problem. Solution: Two piece of flexible lines and extra male QC adapters have been used to
fix this issue. HV cover and HV fence in ITE work with TM2. Other connections are good as well. |
|
Friday, January 27, 2017, 10:52, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 has been moved from TCS to ITE
|
| The move is successful. |
|
Friday, January 27, 2017, 08:50, chad fisher, South Hot-Cell, Standard Operation, , , UCx#18 and Ta#50 autopsy and spent target move
|
| On Thursday, January 26th UCx#18 and Ta#50 were inspected and packaged into spent target pails, move to storage vault. |
|
Friday, January 27, 2017, 08:46, chad fisher, South Hot-Cell, Standard Operation, TM4, Ta#50 , Ta#50 Removed
|
| Ta#50 has been was removed from TM4 on Wednesday, January 25th. |
|
Friday, January 27, 2017, 08:44, chad fisher, South Hot-Cell, Standard Operation, TM2, Ta#50, UCx #18 - Ta Feibiad Dummy installed. Target Change Waterline interference
|
On Tuesday, January 24th UCx#18 was removed from TM2 and Ta febiad dummy installed. I encountered the same issue mounting the new target as last time.
Was able to determine that the issue is the routing of the waterlines to the right-hand (as viewed from the operator) high current tube heater. The lines
interfer the the target mounting plate (bottom right hand corner). |
|
Tuesday, January 24, 2017, 15:32, David Wang, ITW, Standard Operation, TM2, , TM2 was moved from ITW to SHC this morning.
|
| The move is smooth. Yasmine and Travis did the move. |
|
Tuesday, January 24, 2017, 15:29, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 has been moved to TCS .
|
| I connected TCS vacuum system to TM2. The station is under roughing now. All turbo pumps will be started soon. |
|
Tuesday, January 24, 2017, 15:24, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 electrical check and leack check.
|
I did electrical check before and after Fefiad target installation on TM2. The RU (coil) Is till short to 60KV as before. Other result are good. After
Febiad target is installed, Tm2 HS line is leak checked. On leak detector, base leak rate pumping down is much slow than before. The base pressure
still could be pumped down to 0.0XE-4 torr. After a long time wait, Chad and I leak checked at 2.2XE-8 atm.cc/sec base leak rate. Chad sprayed lots |

ITE and TM4 2017 winter shut down leak check are finished. All ITE primary, secondary vacuum vessel and TM4 water lines are good. No any leak has been
found. |
|
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. |
