David W. has installed two SST Proteus flow meters, model OV7006FTA32, on ITW Heat Shield and Coil. The flow meters are connected to a power supply and a data logger in the electrical room.
The Heat Shield flow meter has SN 00278112 and is on the Black wire pairs and connected to CH3 & CH4 on the logger.
The Coil flow meter has SN 00278113 and is on the Green wire pairs and connected to CH1 & CH2 on the logger.
The first channel (CH1, CH3) is temperature in degrees Celcius and the second channel (CH2, CH4) is flow rate in liters per minute.
A camera has been placed on the logger.
Flow rates today (2014-04-04):
HS 8.2 - 8.3 lpm
COIL 8.0 - 8.1 lpm
Calibration sheets
UPDATE 2014-04-11: Corrected HS to CH3 & CH4.

Ta#42 in pail #114 has been moved from the south hot cell to the spent target storage vault and place in spot 7B. The target was 277mSv/hr upon removal from the south hot cell. See attached PDF of vault status. |

The conductance check on the electrical check was found to be outside of accepted values for the TBHT at 7.0 mOhm. A successful attempt to reduce the conductance was made by re-tightening the bolts on the TGHT legs in the SHC. Grant operated the manipulator and torqued the bolts to about 1/8 of a turn with the air ratchet. The conductance across the TGHT (A-B) could be improved from 7.0 mOhm to 6.2 mOhm by re-tightening the bolts. The value is still somewhat higher than usual, but was deemed to be acceptable. Measurements attached. |

1. TGHT leg bolts were loosened, and resistance was measured very high, as expected.
2. TGHT leg bolts were then tightened, loosened, and tightened again, and the resistance improvement was then measured (from 7.0 mOhm to 6.2 mOhm).
3. Another attempt was then made to loosen and tighten to see if there would be further improvement. The right bolt was loosened, but the left bolt was found to be quite stiff and was left as-is (not fully loosened) for fear of breaking the supporting insulator. Both bolts were then re-tightened, and resistance was checked to be about the same as achieved during the previous loosening / tightening attempt (step 2 above).
To tighten the bolts in all cases: the air ratchet was used first to turn the bolts "air tight" (air pedal only, no manual force) and then with the air pedal held down, manual torque was applied to turn no more than 1/8th of a turn. |

The full electrical check was done on October 25th 2013. The results are in the attached PDF. The higher value of the conductance was dealt with see Anders Mjos elog entry for those details. |

TM#4 with Ta#41 has moved to the south hot cell, the move it self was uneventful but, the fields on the module are extremely high when lowering it down into the south hot cell the module had a maximum field of about 392mSv/hr. The shield plug was also installed remotely as well due to the 12mSv/hr field at the top of the west target station due to shine from the dump. |

The spent Ta#41 target has been moved from the south hot cell to the spent target storage vault. It is an unnumbered pail (should be pail 112) and placed in spot 7A of the vault it had a reading of 536mSv/hr upon removal from the south hot cell. See attached PDF for vault details. |
