Heavy Section Steel Technology Program. Irradiation effects on the fracture toughness of heavy section pressure vessel steels. Quarterly progress report for period ending August 31, 1975

Description: The recovery by postirradiation annealing of the irradiation produced shift in the fracture toughness transition of A533-B was investigated. Irradiation embrittlement was reduced by 40% after annealing at 600/sup 0/F for material that had been irradiated to approximately 2 x 10/sup 19/ n/cm/sup 2/ at 550/sup 0/F.

Plutonium-238 dioxide/T-111 compatibility studies

Description: The tantalum-base alloy, T-111, is an ideal radioisotope encapsulant from the aspect of mechanical properties, but unfortunately undergoes severe oxygen embrittlement during long-term, high-temperature exposure to PuO$sub 2$. A study was undertaken in an effort to improve T-111/PuO$sub 2$ compatibility by testing the hypothesis that reduction of fuel stoichiometry to the range PuO$sub 1$.$sub 75$ to PuO$sub 1$.$sub 8$ would suspend the embrittlement process by producing a state of thermodynamic… more

Influence of Microstructure on Stress Corrosion Cracking of Mild Steel in Synthetic Caustic-Nitrate Nuclear Waste Solution

Description: The influence of alloy microstructure on stress corrosion cracking of mild steel in caustic-nitrate synthetic nuclear waste solutions was studied. An evaluation was made of the effect of heat treatment on a representative material (ASTM A 516 Grade 70) used in the construction of high activity radioactive waste storage tanks at Savannah River Plant. Several different microstructures were tested for susceptibility to stress corrosion cracking. Precracked fracture specimens loaded in either const… more
