Subseabed Disposal Project chemical response studies. Annual report, October 1982-September 1983
- ed.
Studies of the chemical response of deep-sea sediments to a subseabed repository for high-level radioactive waste continued during Fiscal Year 1983. Chemical Response Studies comprise Waste Package, Near-Field, and Far-Field Studies. This year, as in the past, investigators in the US Subseabed Disposal Project (SDP) carried out most of these chemical response experiments with red clay from the MPG 1 study location 1500 km north of Hawaii. The results of all studies carried out to date imply that oxidized red clay would form a highly effective barrier to radionuclides that form cationic species, but that anionic radionuclides would begin to escape from the sediment to the overlying water column on the order of thousands of years after emplacement. In Fiscal Year 1984, investigators in the US SDP will initiate chemical response studies with mildly reduced Atlantic clay- and carbonate-rich sediments in cooperation with the Sediment Barrier Task Group of the Organization for Economic Cooperation and Development - Nuclear Energy Agency Coordinated Program on the Assessment of the Subseabed Disposal of Radioactive Waste (Seabed Working Group). The objective of these US studies will be to quantify the chemical response of Atlantic sediments to a subseabed repository with a level of confidence similar to that for Pacific red clay.
