|
Polishing of the water block sealing surfaces has commenced. First attempt was on block B with low nap brown polishing pad (the least aggressive pad
prepared) and isopropyl for 30 seconds. This cleaned a little but did not remove the "ring" which I believe is water scale. I will step up to
2000 grit wet sand paper and iso next. |

|
After trials with 2000 grid wet paper I have moved up to "red" scotch brite. This seems to have worked the best so far although it took two
minutes to remove the ring that the other materials could not remove (see picture).
I have moved to next circuit. Currently at 3 minutes and 30 seconds with scotch brite but significant ring remains. |

This morning new water block fasteners and gas line capture nut fasteners were inserted into the hot cell. Window waterline blank off was removed from
TM2, surfaces inspected and given a polish with Veltex (30 seconds, 70 psi) as there was a small bit of c seal residue. Transfer try with new source tray
has been latched to the module. |

Pail transfer was undertaken in the south hot cell. went very well except near the end the master tong cable of the right hand manipulator broke. Not
entirely a surprise due to the amount of use it has seen lately. |
