Thursday, October 31, 2019, 10:17, David Wang, Assembly/Bench Test, Maintenance, TM2, , Febiad target gas line leak check.
|
Feibiad gas line for ITE and its adapter fittings for TM2 are tested today by installing them on a dummy water stem. No leak on VCO fitting, adapter
o-rings, and all Swagelock fittings of this assembly. Manual valve on gas line works fine. The positional check on gas line between TM2 and ITW will
be fulfilled next Tuesday during module disconnection. |

Friday, November 29, 2019, 13:10, David Wang, ITE, Standard Operation, TM2, SiC 39# febiad, TM2 SiC#39 connection check list.
|
| TM2 has been connected in ITE. All turbo-pumps are started. |
|
Thursday, January 02, 2020, 09:55, David Wang, Cooling, Standard Operation, , , I turned on HALC water pump MP2.
|
HALCW MP2 is switched onnow. There is a small amount of air trapped in system. The pump works fine. Water level and system resistivity will be
monitored for a while.
LALCW P5 and P6 are switched on for cooling HALCW. HALCW MP2 is in operation now. |
|
Thursday, January 02, 2020, 10:10, David Wang, Crane, Standard Operation, , , TH crane issue.
|
Target hall crane does not work properly after TH crane main power is switched off during Christmas time in control room. I switched the main power
back this morning. The only movement could be operated is crane rotation. Power is supplied crane. The control on N-S, E-W and up-down movements
do not work. We had the same problem last year. After trouble shooting, It was pointed to a PLC battery issue. Control group changed the battery and reloaded |
|
Tuesday, January 07, 2020, 08:02, David Wang, Cooling, Standard Operation, , , Switch on HALCW MP2
|
HALCW MP2 is switched on this morning after yesterday cooling tower maintenance. LALCW P5 and P6 pumps are started by isac operator as well. The
system is good so far. |
|
Tuesday, January 07, 2020, 09:37, David Wang, ITW, Standard Operation, , , 5 shielding blocks are moved out of ITW top.

Wednesday, January 08, 2020, 10:34, David Wang, Assembly/Bench Test, Development, , , Module lifting assembly ITA0490
|
The second module lifting assembly ITA0490 is moved into TH and installed onto TM3 . It will stay with TM3. I adjusted the CofG on the assembly.
It is same to the first lifting assembly we are using now. After adjustment, The installation of assembly on TM3 are smooth. |
|
Thursday, January 09, 2020, 14:14, David Wang, Conditioning Station, Standard Operation, TM3, , Start of TCS roughing pump for TM3.
|
| I started TCS roughing pump. TM3 TP1 and TP2 will be started tomorrow morning. |
|
Friday, January 10, 2020, 10:26, David Wang, ITE, Standard Operation, , , ITE water signal inerlock check.
|
| ITE water signal interlock check is done. Everything is good. It is a annual check we do in winter shut down time. |
|
Tuesday, January 14, 2020, 10:12, David Wang, Conditioning Station, Standard Operation, TM3, , Helium spray leak check on TCS.
|
Using a long pole with a probe to spray helium on TCS vacuum seals and joints which are installed in TCS service pit. No response has been found
on leak detector during leak check. TCS is leak free. |
|
Tuesday, January 14, 2020, 10:19, David Wang, Conditioning Station, Standard Operation, TM3, , TCS vacuum system is switched off.
|
TM3 TP1 and TP2 work fine in past 4 days. During operation, The current draw on pumps were 0.7A to 0.8 A. TM3 will be moved back to silo tomorrow.
|
|
Friday, January 24, 2020, 08:19, David Wang, ITW, Standard Operation, TM4, , ITW water signal interlock check.
|
ITW water signal interlock check is done. Everything works fine. ITW 2A2 tank water signal is broken and is not ok on XT2A2 page. I will fix it
next week. |
|
Monday, January 27, 2020, 10:40, David Wang, Cooling, Maintenance, , , ITE/ITW supply water presuure on dump circuits.
|
With both stations in operation,ITE dump supply gauge reading is 27 psi. ITW is 20 Psi. I adjusted ITW dump pressure to 25 psi by changing the
return line side pressure relieve valve.
ITE full operation+ ITW no TM: ITE dump pressure 27psi, ITW dump pressure 27psi. |
|
Wednesday, January 29, 2020, 12:37, David Wang, ITE, Standard Operation, TM2, , ITE primary/secondary vacuum vessel leak check.
|
Leak check on ITE vacuum vessel is done. LD base leak rate 0.0XE-9atm.cc/sec. base pressure 0.0Xe-4torr. Sprayed helium on all ITE primary and secondary
vacuum vessel seals(including TM2). No leak . Also,70psi helium pressurized TM2 waterlines inside the module for each circuit 3 minutes. No leak
on all operating TM2 waterlines. |
|
Thursday, January 30, 2020, 10:22, David Wang, ITW, Standard Operation, TM4, , TM4 water lines helium pressure leak check.
|
TM4 internal water lines helium pressure leak check at ITW : 70psi helium 5 minutes on each circuits. Base leak rate 0.0X E-9 atm.cc/sec.
Base pressure 0.0X E-4torr. Only B line(Oven -) has a tiny 1.5Xe-9 atm.cc/sec response on LD during the check . All others all perfect good. |
