Subject: Hot cell Entry February 25 2015 

See attached report.

Summary:

Radio problems just before entry to cell. Inspection afterwards revealed batteries charge but battery in one radio shorts out after a couple loads/cycles.

Fields in hot cell range from 630 uSv/h @ 1 m to 1.5mSv/h @ 1m. Contributing to the fields is the febiad coil line removed from TM4 in the south west corner of the hot cell.

Contamination/particulate on table as mostly black colored and of a fairly substantial size, but seamingly easy to collect. Distinquishable pieces of target material present.

Hot cell window show no sign of leaking on the inside of cell.

Pre-filter changed.

Manipulators lubricated.

Hot cell entry procedures appear to still be fairly successful in minimizing contamination migration from the hot cell.
