TMI-2 EPICOR-II Resin/Liner Investigation: Low-level Waste Data Base Development Program for Fiscal Year 1989

Abstract

The TMI-2 EPICOR-II Resin/Liner Investigation: Low-Level Waste Data Base Development Program is funded by the US Nuclear Regulatory Commission (NRC). The purpose of this program is to: (a) study the degradation effects in EPICOR-II organic ion exchange resins caused by radiation (resin degradation), (b) examine the adequacy of test requirements of 10 CFR 61, using waste forms containing solidified EPICOR-II resins (resin solidification), (c) obtain performance information on solidified EPICOR-II ion exchange resins in a disposal environment (field testing), (d) determine the condition of EPICOR-II liners (liner integrity examination). This report summarizes accomplishments of Fiscal Year 1989. The third sampling of ion exchange resins from EPICOR-II prefilters PF-8 and -20, to determine degradation, is described. Results of the fourth year of data acquisition from the field testing are presented and discussed. During the continuing field testing, both Portland Type I-II cement and Dow vinyl esterstyrene 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 to provide continuous data on nuclide release and movement, as well as environmental conditions, over a 20-year period. All work in the liner integrity examination studies was completed inmore » FY-1984. 17 refs., 42 figs., 12 tabs.« less
