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,
The goal of the triagency SP-100 Program is to develop long-lived, compact, lightweight, survivable nuclear reactor space power systems for application to the power range 50 kWe to 1 MWe.
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.
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
Masses and radiator areas of typical space nuclear power concepts are estimated as a function of the continuous electrical power required during a ten-year mission. Results are presented as a function of power level in the range of 5 to 1000 kW electrical.
1 lip 1994 · The current phase of the SP‐100 program was initiated in 1986 with the objectives of developing the technology for Space Reactor Power Systems (SRPSs) in the 10–1000 kWe power range and performing ground system tests of both nuclear and non‐nuclear major assemblies.
Use of closed Brayton cycle (CBC) power conversion technology has been investigated for use with SP-100 reactors for space power systems. The CBC power conversion technology is being developed to provide highly efficient power conversion with radioisotope and solar collector heat sources.
