2. Equipment Decontamination
a. Regulated Steam Pit
A total of 7 pieces of equipment and 14 vehicles were
decontaminated during the month. The total manhours
charged to decontamination work was 236. Of this total

and timekeeping at Riverland.
b. 221-U Building
Two Redox pumps were decontaminated in the 221-U Canyon
during the month. Radiation levels were reduced from
8.5 rads/hr to a maximum of 150 mr/hr at 2 inches. These
units were cleaned with a solution of caustic and per-
manganate followed by a nitric acid wash. Inspection
after disassembly of the first unit by Engineering and
Operation Personnel revealed bearing failure, which in
turn scored the shaft. Repair work on this unit is
