The following work was completed on the T1 cooling package:
- water drained to BL1A holding tank
- all resevoir o-rings changed
- all cuno filters changed:
M15 permanent magnet filter < 5uSv/hr at 0.5m, dark grey colour
Target inlet filter 210uSv/hr at 0.5m, light brown colour
Resin filter, <5uSv/hr, looks clean and new
- package re-filled and started
- demin circuit flow tuned to 1.0gpm
- #6 female Hansen fittings at target end of flexible hose swapped for previously used SS models (zinc coated steel models (PO# TR207041) were accidentally ordered and installed last shutdown and had black corrosion on the inside)
The T2 cooling package was also drained to the 1A holding tank.
After approval from RPG the holding tank water was released.
Note: the appearance of the used cuno filters is consistent with previous years. |
