Title: Annual report of the TMI-2 (Three Mile Island Unit 2) EPICOR-II Resin/Liner Investigation: Low-Level Waste Data Base Development Program for fiscal year 1988

Technical Report ·
OSTI ID:5567325

The TMI-2 EPICOR-II Resin/Liner Investigation: Low-Level Waste Data Base Development Program, funded by the US Nuclear Regulatory Commission (NRC), is studying the degradation effects in EPICOR-II organic ion exchange resins caused by radiation; examining the adequacy of test procedures recommended in the Branch Technical Position on Waste Forms to meet the requirements of 10 CFR 61 using solidified EPICOR-II resins; obtaining performance information on solidified EPICOR-II ion exchange resins in a disposal environment; and determining the condition of EPICOR-II liners. This report summarizes accomplishments of Fiscal Year 1988. The steps taken in preparation for the third sampling of ion exchange resins from EPICOR-II prefilters PF-8 and -20 determine degradation are noted under the Resin Degradation Task. In the Resin Solidification Task, the results of leachate analysis for Sr-90 are presented. The leachate samples were obtained from testing of waste forms after irradiation. Those results are compared to results from irradiated and unirradiated waste form Cs-137 leachate sample analysis. In the Field Testing Task, both Portland Type I-II cement and Dow vinyl ester-styrene waste forms are being tested in lysimeter arrays located at Argonne National Laboratory in Illinois (ANL-E) and Oak Ridge National Laboratory (ORNL). The study is designed so that continuous data on nuclide release and movement, as well as envirnomental conditions, will be obtained over a 20-year period. results of the third year of data acquisition are presented and discussed. 14 refs., 41 figs., 8 tabs.
