Design, Testing and Fabrication of Heart Sources for Underwater Application

摘要

The sequence of events in the design, testing and fabrication of a radioisotopic heat source using available plu-tonium-238 dioxide fuel that would be amenable to a Navy 0.5-W (electrical) Radioisotopic Thermoelectric Generator for undersea application is discussed. Various designs were considered as a function of heat leak in order to adopt the most desirable capsule for a volume-constrained application. Testing considerations are discussed for capsule compliance with IAEA/ENEA Safety Series 6 and 33 and 10CFR71.
