Abstract: Describe herein is an energy storage system that includes a battery and a heat source. The battery harvests waste heat from the heat source to keep itself warm while storing electrical energy generated from a heat to energy transforming source. If the heat source is radioactive (e.g. radioisotope decay) a radiation hard battery is intimately connected to a waste heat source. The radiation hard battery harvests waste heat from the heat source to warm itself and to shield the radiation.

Abstract: A semiconducter battery that utilizes radioactive decay processes to produce electrical power by direct electrical current generation from these decay products. These batteries have extremely long half-lives. Each decay can produce on the order of 1,500,000 free electrons and 1,500,000 ions per each radioactive decay, so there is a tremendous multiplication factor for current generation. Production of these batteries by semiconductor processes greatly reduces battery cost compared to existing batteries that utilize radioactive decays. The battery comprises a n-type semiconducter layer, a radioactive semiconducter layer sandwiched between two adjacent layers of semiconducter material not containing radioactive material, and a p-type semiconducter layer.

Abstract: A method for stabilizing direct current generated by neutron activation of a plurality of interconnected .beta.-emitter (nuclear decay electron) cells, which are placed in a specific position in the out-of-core region of a light water nuclear reactor. The method entails a synergistic combination of neutron-absorbing isotopes, in specific relationship to each other, the amount of each absorber and their respective locations in the neutron flux field being chosen to render the total current-time characteristic substantially constant over a significant number of reactor full-power-years. The method enhances the current output and lifetime of the current generator by greatly deferring burn-up of the neutron absorbers. If configured as a DC voltage source for powering radiation-hardened, high-temperature integrated circuitry contained in the reactor pressure vessel, voltage regulation circuitry is not necessary.

Abstract: An apparatus for protecting personnel and the environment from harmful emissions of radiation from a source thereof includes a plurality of shielding parts so located as to be in the path of the radioactive emissions and to absorb them so that an electrical potential difference between the shielding parts is established, due to different absorptions of radiation by them, a variable electrical load for consuming electrical power at a location remote from the radioactive source, and electrical conductors communicating the variable electrical load with such shielding parts. Although the invention is primarily intended for protecting personnel and the environment against emissions from radiation sources, such as radioactive wastes, it is also useful for shielding other sources of harmful radiated emissions. Also within the invention are processes for protecting personnel and the environment against radiation hazards.
