David Wang | Conditioning Station | Maintenance | | | Three manual valves are closed on TCS water system |
Three manual valves are closed on TCS water system return line in experimental hall. See attachments. It is for TCS TK2 water level slow drop trouble shooting. These valves will be opened again right after troubleshooting.
TCS TK2 water level no change(11.1 inches) in this week after valves are closed. I will keep these three valves closed for one more week.
I opened these valves. In two week times, The TK2 level dropped 0.1 inches. The water level change could be a result of evaporation of water in system. We will keep watching on it. |

David Wang | ITW | Repair | | | ITW water leak. |
A water leak was found on a fitting connecting ITW dump return line pressure gauge on top of exit module. TM tank flange, o-ring slot and o-ring were contaminated by water and water rust. Frank and I cleaned the flange and o-ring slot . We changed a new TM tank o-ring, vacuumed around other 3 module flanges. The leak fittings with pressure gauges were removed . I put a blind cap on removed fitting spot.. Water are switched back to ITW. No leak on blind cap. |

David Wang | ITE | Maintenance | | | Restart of ITE turbo pumps. |
PLC6 drop out in weekend caused the ITH MP1 and MP1s stopped. ITE turbo pumps were running still after that. Without back up pump, TPs started to trip off later . I found TP1,TP3, and TP4 were tripped off this morning. And , The rest pumps ran with high current draw. Jon Aoki restarted back up pumps and ITE turbo pumps. The ITE vacuum system works fine now. |
