Stabilized in-vessel direct current source |
| 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. Typically, the useful lifetime is rendered independent of output current and can be extended indefinitely, thereby greatly reducing replacement costs. |
