|
We have a ram installed on SHC pole which is 0.5 meter to module shielding block surface. the readings we got today during TM3 move:
at containment box center (highest reading): 3.14 msv/hr.
at bottom of shielding blocks: 960 usv/hr. |

A video inspection of the lower service tray was performed this morning. Camera was inserted upwards into the service tray/service chase from the containment
box. One potential spark mark was identified as well as epoxy not flush with insulator. Fiberglass does not extend into service tray/chase much and does
not look, from initial inspection that it will be too difficult to remove. |

Gordon Crane technician Tom Kauss finished the replacement of the east side main hoist brake assembly. A new set up is installed. he adjusted gap too
close during first time try. So, the smell appeared when operate the brake. He increased the gap to a proper distance then. It looks like everything works
fine now. Still, The brake need to be tested with 10K lBS load on it. We will do the load test on next Thursday when he come here to replace west side |

Anders and I found a low frequency issue(13hz only) on TCS TGHT flow sensor when doing TM4 conditioning. By trouble shooting, We found the module water
lines are good. the restriction cause this problem in on TCS supply or return water lines to TGHT. I switched TGHT lines with MSP water lines. The
wheel frequency on TGHT is 67.0hz which is pretty high. Now, MSP is using the original TGHT water line(flow sensor frequency 13hz). Flow sensors and |

|
When lifting up TM2 (20000lbs) this afternoon, TH crane has a strange noise on main hoist. The module was lift up less than 1 feet.when strange
sound was noticed. The module move was stopped right away,and module was lowed back to SHC. The strange noise was confirmed later with SEG
block six inches lifting up. Gordon crane technician will be here to tomorrow morning to investigate the problem. |

TCS IG1S is switched on as well. The reason to start the pump is to prepare a possible extended TM2 conditioning at TCS caused by TH crane issue.
TCS:TP1 and TP2 are not switched on for this. |

TM2 was moved and connected in ITW yesterday afternoon. After roughing down, ITW turbo pumps are started. ITW TP4 can not be started to full speed. ISAC
ops kept it at low speed mode with less than 1.0A current draw on pump. ITW IG1s shows red as well. I will take a look on them today when beam is off.
