Title: IRRADIATION OF CLAD GRAPHITE IN HIGH-TEMPERATURE HIGH-PRESSURE CO$sub 2$

Abstract

Graphite specimens fully clad with Type 310 stainless, Type 446 stainless, or Inconel were irradiated in a 1000-psi CO/sub 2/ environment for a period of 4 weeks at approximately 1300 F followed by 1 week at 1500 F. The fast-neutron-plus-gmma dose rate was estimated at 8 x 10/sup 7/ rads per hr. The gas environment was sampled and replenished eight times during the experiment. After 60 hr at about 1350 F, the CO content had in creased from a negligible value to 3.6 vol. %. It then decreased steadily to a value of 0.4 vol. % at the end of 4 weeks. When the temperature was raised to 1500 F, the CO content increased to 1.9 vol, % in 100 hr and then decreased to 0.6 vol. %. The O content remained nearly constant throughout the experiment. Postirradiation examination and metallography revealed very little effect of the exposure on the cladding materials at the gas and graphite interfaces. (auth)
