238PuO2 Surface Contamination of Radioisotopic Heat Sources

1979
Radioisotopic thermoelectric generators (RTG’s) employ the self-heating characteristic of decaying radioactive material (in this case, plutonium-238) to generate electricity. The highly radioactive fuel presents the disadvantage of requiring isolation to prevent environmental contamination.

Development of a radioisotope heat source for the two-watt radioisotope thermoelectric generator

AIP Conference Proceedings, 1992
Described is a radioisotope heat source for the Two‐Watt Radioisotope Thermoelectric Generator (RTG) which is being considered for possible application by the U.S. Navy and for other Department of Defense applications. The heat source thermal energy (75 Wt) is produced from the alpha decay of plutonium‐238 which is in the form of high‐fired plutonium ...

Safe radioisotope thermoelectric generators and heat sources for space applications

Journal of Nuclear Materials, 2008
Several isotopes are examined as alternatives to 238Pu that is traditionally used in radioisotope thermoelectric generators (RTGs) and heating units (RHUs). The radioisotopes discussed include 241Am, 208Po, 210Po, and 90Sr. The aim of this study is to facilitate the design of an RTG with a minimal radiation dose rate and mass including any required ...

Thermal Preconditioning Utilizing a Radioisotope Heat Source

Navigation, 1970
Gyroscopes and accelerometers used as sensors in inertial navigation systems have errors which change with temperature. In order to obtain adequate performance from these devices; precise, elevated (above ambient) temperatures are usually required to aid in maintaining close tolerances of temperature control.
