LIQUID RADIOACTIVE WASTE DISPOSAL FACILITY
Abstract
A liquid radioactive waste disposal facility was installed at Nuclear Defense Laboratory for extensive tests and evaluation. The facility is being used for concentration of radioactive wastes from the Army nuclear power program and biological and medical research. It employs a Pfaudler Wiped Film Evaporator to effect gross decontamination of the waste and concentration of the waste by a factor of approximately 100. Condensate from the evaporator is further decontaminated by passage through Permutit mixedbed demineralizers. The facility is a selfcontained, transportable, semi-automatic assembly of monitoring, feed, and residue tanks, pumps, control panel, and ancillary equipment mounted on a skid. Results of preliminary evaluation tests using feed spiked with Co-60 to an activity greater than 8.7 x 10 to the -4 microcurie per ml in beta indicate an over-all DF of approximately 10 to the 6th to 7th power. Initial test results did not determine ultimate facility capability because of errors in the vent piping, which have been corrected, and analytical limits imposed by background activity. DF for alpha appears to be about 1000.
