RADIOISOTOPE FUELED AUXILIARY POWER UNIT. Quarterly Progress Report No. 5, January-April 1958

Technical Report · Wed Oct 30 23:00:00 EST 1963

OSTI ID:4684058

Progress made in the development of the radioisotopefueled thermoelectric generator (SNAP-1) is reported. Shipping procedures and the boiler loading and installation philosophy were determined. The core integrity test program was defined in further detail to include tests to evaluate launch abort damage and simulate re-entry heating conditions. A shielding analysis, to facilitate design of the boiler insulation and biological shield, was completed. Assembly of the mockup boiler heat transfer loop was completed and initial testing started. Engineerirg drawings for the new half-power boiler were completed and fabrication initiated. Development testing continued on CeO/sub 2/ pellets to improve stability and corrosion resistance. A corrosion program to determine the effect of biological shield mercury on surface emissivities of insulating metal was initiated. Development of the power conversion system components (turbine, pump, controls, alternator, and bearings) was continued. (N.W.R.)
