Title: Efficient, Long-Lived Radioisotope Power Generator
Agency: NASA
Contract: NNX11CE12P
Award Amount: $99,999.00
 

Abstract:

Radiation Monitoring Devices, Inc., (RMD) proposes to develop an alternative very long term, radioisotope power source with thermoelectric power conversion with greater than 10% energy efficiency for deep space applications. The proposed technology is based on a betavoltaic generator which can be produced in bulk form, allowing the construction of generators with power output similar to radioisotope thermal generators (RTG) but with higher efficiency. In Phase I, RMD will estimate the potential performance of the betavoltaic generator, examine practical issues affecting manufacturability and lifetime, and experimentally demonstrate components of the proposed betavoltaics generator. The Phase I results will provide clear "Go-No Go" results. The goal of Phase II is to complete the research and development on the betavoltaic generator technology, and to build and test a small prototype system with at least 10% conversion efficiency. A major focus of Phase II will be the development of the crystal growth process including dispersing radioactive sources within the scintillator. By the end of Phase II, the generator technology will have been demonstrated and ready for further engineering to bring it to a more advanced level (TRL-6) in 2 to 3 years.
