OSTI ID:6545759
Current work is organized into six tasks: (1) program administration and procurement, (2) fracture-mechanics analyses and investigations, (3) investigations of irradiated meterials, (4) thermal-shock investigations, (5) pressure vessel investigations, and (6) stainless steel cladding investigations. Comparison of two- and three-dimensional analysis of a vessel subjected to a pressurized-thermal shock (PTS) indicates that finiteness of flaws is important. Subcontractors investigated phenomena related to crack-arrest toughness and cleavage-fibrous fracture transitions. Irradiations of the Fourth HSST Irradiation Series were completed, and work commenced on additional irradiations. Overcooling accident analyses were also made. Intermedite vessel test V-8A was successfully conducted with the attainment and interruption of unstable tearing. Construction of the PTS test facility commenced. Additional clad-plate tests were conducted and planned.
