Measuring the Combined Effects of Nuclear Radiation and Cryotemperatures on the Tensile and Shear Properties of Materials
The employment of nuclear power in space, either for propulsion or as a source of electrical power, will introduce the potential problem of radiation damage to mechanical and electronic components as well as to basic materials of construction. The extensive use of cryogens proposed for use in these vehicles and the exposure of many component parts to the cryotemperatures of outer space will impose the added environment of very low temperatures to many of the materials and components involved. Reliable designs of spacecraft employing nuclear power will therefore depend upon the utilization of all available information pertaining to the effects of radiation, in combination with high or low temperatures, on materials and components.
