Behavior of oxygen partial pressure over slightly substoichiometric plutonia at 1410/sup 0/K

Description: Monsanto Research Corporation is charged with processing encapsulated plutonium dioxide heat sources into radioisotopic thermoelectric generators (RTGs) to support deep-space missions. One of the problems associated with the sometimes protracted ground storage of these devices is the ingrowth of carbon dioxide and carbon monoxide in the gas phase due to the cyclical reaction established between the fuel (/sup 238/PuO/sub 2/) and the carbon impact body. This ingrowth proceeds according to the tw… more

Evaluation of hydrogen embrittlement in Cr-Mo pressure vessel steels. Topical report No. 1

Description: Commercial 2-1/4 Cr-1 Mo low strength steel specimens have been tested to measure their susceptibility to hydrogen embrittlement in an environment of H/sub 2/S at 50 psig. It was found that two factors, viz. (i) the plane stress zones on the crack front in compact tension specimens and (ii) incubation time effects, seriously confounded measurements on these steels when tested by conventional rising load experiments. Because of the incubation time effect, K/sub or/ (the stress intensity at which… more
