Abstract

A METHOD AND APPARATUS FOR REMOVING IODINE-131 AND IODINE-125 FROM A LIQUID SODIUM REACTOR COOLANT. NONRADIOCATIVE IODINE IS DISSSOLVED IN HOT LIQUID SODIUM TO INCREASE THE TOTAL IODINE CONCENTRATION. SUBSEQUENT PRECIPITATION OF THE IODINE IN A COLD TRAP REMOVES BOTH THE RADIOACTIVE IODINE ISOTOPES AS WELL AS THE NON-RADIOACTIVE IODINE.

PUBLISHED MARCH 5, 197i T920,001 METHOD AND APPARATUS FOR REMOVING IODINE FROM A NUCLEAR REACTOR COOLANT Martin H. Cooper, Monroeville, Pa., assignor to Westinghouse Elecn'ic Corporation, Pittsburgh, Pa. Filed June 15, 1972, Ser. No. 263,054 Int. Cl. C01b 7/14; G21c 19/30 US. Cl. 176-37 1 Sheet Drawing. 14 Pages Specification A method and apparatus for removing iodine-131 and iodine-125 from a liquid sodium reactor coolant. Nonradioactive iodine is dissolved in hot liquid sodium to increase the total iodine concentration. Subsequent precip itation of the iodine in a cold trap removes both the radioactive iodine isotopes as well as the non-radioactive iodine.
