single SP-100 reactor located in a cylindrical hole with surface-mounted Brayton engines and radiators. Man-rated radiation protection is provided through the emplacement of the reactor in the excavation. Despite the crew availability this powerplant is designed for quick and easy assembly.
Nuclear Reactor The SP-IOOnuclear reactor is a lithium cooled, uranium nitride fueled, fast spectrum reactor. Its nominal design is for 2.5 MWof thermal (MWT) power to assure that I00 kWecan be produced from the thermoelectric convert-ers. The technology is scalable from I0 to I000 kWe. The fuel enrichment,
reactor design options and fuel enrichment levels. They evaluated two reactor concepts: a) a fast-spectrum SP-100 derived system using UN pin fuel with pumped Li primary heat transport, and b) a derivative of the Transformational Challenge Reactor (TCR) using UN particle fuel in a solid SiC element with interspersed YH moderator.
The heat source for thermoelectric power generation in the SP-100 reactor design is a core of fuel pins fabricated from high-density uranium nitride (UN) fuel, a rhenium liner, and niobium-1% zirconium (NblZr) alloy cladding.
1 wrz 2023 · The SP-100 was a fast spectrum, lithium-cooled reactor design that employed UN fuel. It was designed to use a thermoelectric power conversion system, with electromagnetic pumps to force the coolant through the core to the thermoelectric modules.
purpose: 1) to review the design status, an of October 1982, of the SP-100 heat pipe space nuclear reactor system (Refs. 2 and 14), and 2) to identify technical areas, components, and systems requiring additional research needed to support continued SP-100 system development.
1 lut 2022 · The preliminary safety analysis for the SP-100 nuclear power system under URIA and LOHA shows that the lithium-cooled reactor coupled with the Stirling cycle has satisfactory service performance and accident tolerance ability.
