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, funded by the US Nuclear Regulatory Commission (NRC), 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 (INEL). This report summarizes results and analyses of the second sampling of ion exchange resins from 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 is continuing due to the high internal radiation dose received by the EPICOR-II resins. Results also are compared with results from the first sampling of the resins from EPICOR-II prefilters PF-8 and PF-20, and with those of other researchers.
