Radioisotope Thermoelectric Generators Emplaced in the Deep Ocean, Recover or Dispose in Situ
Abstract
The purpose of this report is to consider the risk to man of in situ disposal of the RTGs versus recovery for ultimate disposal at a terrestrial site. A description of the RTGs, their emplacement sites, and their ability to contain the strontium-90 while exposed to a deep-ocean environment are provided. For in situ disposal, the strontium-90 concentration in seawater is calculated and the resulting dose to man estimated. Summaries of earlier safety analyses which considered in situ disposal are also included. For disposal at a terrestrial site, recovery of the RTGs from the deep oceans must utilize the submersible vehicle TRIESTE, Descriptions of this vehicle, a typical mission, and an attempted TRG recovery are included. Also, a general appraisal of the risks involved in the recovery and terrestrial disposal of the RTGs is provided. Finally a conclusion is drawn regarding the merits of the disposal alternatives. The risk to man of disposing, either in situ or by recovery and removal to a terrestrial site, of radioisotope thermoelectric generators deployed in the oceans is evaluated. It is concluded that in situ disposal will have benign consequences, whereas recovery would entail significant nonradiological hazards. In situ disposal is recommended.
