Six 5 gallon pails were transferred this morning from a temporary storage bunker in the Warm Cell to the Rad Waste Pit for long term storage. The pails contain various BL1A active waste from the East Hot Cell including dozens of irradiated beryllium and graphite targets. The field from the pails ranged from 0.1 to 9mSv/hr at 0.5m. The work was performed according to the clean-out procedure (Document-142965). Photographs and records of the pail contents, field, weight, etc have been uploaded to Docushare Collection #20185 and hard paper copies were given to RPG.
All remaining waste in the east hot cell is too large to fit into 5 gallon pails, so it must be packaged in a 55 gallon drum. Some long items will need to be cut in the cell before hand.
The field on the hot cell roof is now less than 5uSv/hr in working areas, and a maximum of 55uSv/hr at 0.5m above the east hot cell opening. The field was previously > 50uSv/hr in some working areas, and > 200uSv/hr above the opening.
Before and after photos of the hot cell interior are included below:
