Design and preparation of an equivalent radioisotope heat source and its performance test
He jishu, 2023 BackgroundA general-purpose heat source (GPHS) is the most established heat source module for radioisotope thermoelectric generators (RTGs) and a key reference for the equivalence of electrically heated analog heat sources during the development and ...

Self-induced electrostatic-boosted radioisotope heat sources [PDF]
Progress in Nuclear Energy, 2015 © 2015 Elsevier Ltd.All rights reserved. In this paper the possibility of stimulated self-induced electrostatic fields in radioisotope heat sources for power enhancement is discussed. Because electrons have higher mobility than the positively charged fragments from radioactive decay, a build-up of positive charges can be promoted, leading to an ...

Helium release from radioisotope heat sources [PDF]
, 1984 Diffusion of helium in /sup 238/PuO/sub 2/ fuel was characterized as a function of the heating rate and the fuel microstructure. The samples were thermally ramped in an induction furnace and the helium release rates measured with an automated mass spectrometer.

Radioisotopic heat sources. Revision 1 [PDF]
, 1963 For the radioisotopes with half-lives over a year, only eight appear to be obtainable in the foreseeable future. The fission products, strontium-90, cesium-137, and promethium-147, exist in wastes from reactor processing, diluted with enormous volumes of other elements and salts.

The Separation of 241Am from Aged Plutonium Dioxide for use in Radioisotope Power Systems
E3S Web of Conferences, 2017 Electrical power sources used in outer planet missions are a key enabling technology for data acquisition and communications. State–of-the-art power sources generate electricity from alpha decay of 238Pu via thermoelectric conversion. However, production

Radioisotopes for heat-source applications [PDF]
, 1982 Potential DOD requirements for noninterruptable power sources could total 1 MW thermal by FY 1990. Of the three isotopes considered, (/sup 90/Sr, /sup 147/Pm, /sup 238/Pu) /sup 90/Sr is the only one available in sufficient amounts to meet this requirement.

Assessment of dynamic energy conversion systems for radioisotope heat sources [PDF]
, 1985 The use of dynamic conversion systems to convert the heat generated in a 7500 W(t) 90 Sr radioisotopic heat source to electricity is examined. The systems studies were Stirling; Brayton Cycle; three organic Rankines (ORCs) (Barber-Nichols/ORMAT, Sundstrand, and TRW); and an organic Rankine plus thermoelectrics.
