NERVA MATERIALS IRRADIATION PROGRAM. VOLUME 3. GTR TEST 17 - AGC MATERIALS TEST
Abstract
The purpose of this test was to determine the combined effects of nuclear radiation and liquid hydrogen on the mechanical properties of various organic materials scheduled for use in conjunction with the NERVA propulsion system. The test consisted of the irradiation and subsequent tensile testing, under several different environmental conditions, of specimens made from the following materials: (1) Armalon TFE-405-CL-116, (2) Armalon TFE-405-L-112, (3) Armalon FEP-510-L-128, (4) Teflon ep, (5) Superpolymer SP-3. The specimens submerged in liquid hydrogen were irradiated in the three cryogenic tensile test assemblies utilized previously in GTR-16 (GD/FW Report FZK-263-1). An analysis of the mechanical property data indicates that the specimens of the three Armalon materials exhibited a high degree of damage at the high-dose condition. A definite, although generally minor, effect was measured at the intermediate level, and no damage was detected at the low dose level. A similar trend was encountered in the Teflon FEP material, except that a more significant effect was detected at the intermediate dose level. The fifth material tested was Superpolymer SP-3, which exhibited no radiation-induced damage at any of the dose levels.
