Tensile, Compression, and Shear Loop for Irradiation Testing at Cryogenic Temperatures
This paper describes primarily the developmental testing programs associated with the tensile-compression irradiation test loop which will be used to obtain the mechanical properties data on more than 24 space-related alloys under the combined environment of cryogenic temperatures to 30°R, a maximum integrated neutron dose of 1019 nvt and stress to failure. Because of the neutron dose requirement, the radiation phase of the test program will be conducted in beam hole HB-2 at the NASA Plum Brook Reactor Facility. Figure 1 is a schematic of the experimental arrangement at this facility. A closed-loop helium-gas refrigeration system for this arrangement has been described by Liebschutz and Schulte. A transfer table to rotate and translate the test loop between the reactor beam port and hot cave in the pool, the air lock, bridge cart, and hot cave have also been described in various reports.
