 Monday, February 10, 2025, 16:52, Albert Kong, Standard Operation, Target 1, Cooling, T1\T2 Cooling Packages Refill and Restart 6x
|
The T1 cooling package was refilled to ~38cm and restarted. Shortly after restarting reservoir level dropped and settled to 37.8cm.
No visible leaks when viewed from the Meson Hall south walkway,level seems steady after ~1 hour of operation, water conductivity also returned
to normal after a few minutes of flow. |

|
The uncovered VA8 section of beam pipe was surveyed in preparation for a visual inspection and some laser scanning.
Fields around the East and West elevated ledges of the beam pipe were around 100 uSv/hr. The pole monitor registered around 2mSv/hr on contact
with the beam pipe indium joints. |
