The 28 March 1979 accident at Three Mile Island Unit 2 released approximately 560,000 gallons of contaminated water to the Auxiliary and Fuel Handling Buildings. The water was decontaminated using a demineralization system called EPICOR-II developed by Epicor, Inc. The Low-Level Waste Data Base Development-EPICOR-II Resin/Liner Investigation Project, founded by the US Nuclear Regulatory Commission, is studying the chemical and physical conditions of the synthetic ion exchange resins found in several EPICOR-II prefilters. The work is being done by EG and G Idaho, Inc. at the Idaho National Engineering Laboratory. This report summarizes results and analyses of the first sampling of ion exchange resins form EPICOR-II prefilters PF-8 and 20. Results are compared with baseline data from tests performed on unirradiated Epicor, Inc. resins to determine if degradation had occurred due to the high internal radiation dose received by the EPICOR-II resins. Results also are compared with resent findings on resin degradation by Battelle Columbus Laboratories and Brookhaven National Laboratory. 16 refs., 46 figs., 6 tabs.
