SP-100 reactor for lunar surface power system applications. Two designs were characterized and modeled. The first design integrates a 100-kWe SP-100 Brayton power system with a lunar lan-der. This system is intended to meet early lunar mission power needs while minimizing on-site installation requirements.
An update on the SP-100 reactor subsystem design and performance is provided. Several key requirements have influenced the design substantially as the more detailed nuclear, thermal/hydraulic, and structural analyses have been completed for the various mission phases including accident safety performance characteristics.
The NASA, DOD, and DOE triagency SP-100 Pro- gram has recently embarked on a major effort to demonstrate the technology readiness of nuclear reactor space power systems for space applications by 1992. This program is termed the SP-100 ground engineerin system (GES) in which system safety and typica? reactor and aerospace (conversion,
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,
a space nuclear reactor power system program known as the Space Power-100 (SP-100) Development Project. The program is presently in the critical technology phase. This phase, better known as technology assessment and advancement, includes mission requirements definition, system conceptual designs, and critical technology development. A
1 lip 1994 · The design activities cover power levels from 5–100 kWe, technology ranging from currently available through projected evolution, and incorporation of features to enhance survivability. The designs demonstrate the adaptability of the basic technology developed in the SP‐100 Program.
1 sty 1991 · The SP‐100 Program is developing a nuclear reactor power system that can enhance and/or enable future civilian and military space missions. The program is directed to develop space reactor technology to provide electrical power in the range of tens to hundreds of kilowatts.
