Title: SNAP-50/SPUR program engineering progress report, October 1, 1963--December 31, 1963

Abstract

Declassified 6 Sep 1973. A design study of the integration of the SNAP- 50/SPUR power plant with a space craft for use with the Titan 111C launch vehicle was completed. Reference Reactor Design No. 2 (8 Mwt) was integrated into the SNAP-50/SPUR power plant design. Emphasis has been shifted to Reference Reactor Design No. 3 (2 Mwt) which is based on a maximum fuel temperature of 2300F and a maximum fuel burnup of 1.5 percent. Environmental tests of control drive components were continued utilizing residual LCRE material. Test temperatures were increased to those of interest for SNAP-50/ SPUR. The four-inch pressure vessels completed 9139 and 7896 hours of their scheduled 10,000 hour tests. The full-scale LCRE prototype vessel completed 4800 hours of a 10,000 hour test. A pressure vessel test program was initiated for SNAP-50/SPUR designs using ten- inch vessels. Data on potential SNAP-50/ SPUR fuels indicate that serious limitations may exist at design conditions associated with Reference Design No. 2 (8 Mwt). Modifications to the fuel testing program were made to provide an evaluation of fuels at conditions corresponding to those used for Reference Reactor Design No. 3 (2 Mwt). Design was continued on the power plant pumps andmore » drive motors. A preliminary dynamic analysis of the SNAP-50/SPUR power plant was completed on the CANEL electric analog computer. Testing of the Haynes25 alloy boiling heat transfer loop was continued to 3600 hours at which time a loop failure terminated the test program. The stainless steel boiling potassium loop was discontinued after 2265 hours of operation due to a failure in the boiler. The NonNuclear Systems Test was interrupted at 4021 hours by a water leak in the electrical heater cooling circuit. The materials program was continued in support of the SNAP-50/SPUR development effort. A natural convection potassium loop has completed 1655 hours of testing in a vacuum environment. (auth)« less
