It was discovered this morning that the Evaporator #2 chiller was leaking water from the bottom (see attachment 1). A puddle of water was
formed and eventually found its way down to the Hotcell. |

Note: LP-FEBIAD target container ( W.O#37918-3) was coated with TaC and sintered on July 19 for UCx#5 target. Then, a last minute request
from the Sci Dev. to run the UCx#5 in LP-SIS. |

The insulator that holds the terminals was broken when a target container was installed. The insulator had seen so much heat shine from the
Cu heat-shield gaps, see attachment. Tightening the bolts on the target container might further put more force on the insulator and eventually broke |
