Thermoelectric generator, RTG, radioisotope powered, electrical power, underwater power, 

 heat transfer, natural convection, undcr-ocean heat rejection surface. 



In support of a larger effort of the Nuclear Division, Naval Facilities Engineering 

 Command. CEL undertook to design, build, and test the heat rejection portions of a 

 large 2-kw(c) radioisotope thermoelectric generator (RTG). The design was optimized 

 to produce the lowest practicable temperatures at the co'd junction of a Lirge number of 

 thermoelectric heat-to-clcctncity conversion elements. The geometry W2S largelv defined
