The investigation focuses on the behavior and structural integrity of steel pressure vessels containing cracklike flaws. Current work is organized into seven tasks: (1) program administration and procurement, (2) fracture-mechanics analyses and investigations, (3) investigations of irradiated materials, (4) thermal-shock investigations, (5) pressure vessel investigations, (6) stainless steel cladding investigations, and (7) environmentally assisted crack growth studies. A superposition solution technique for determining stress-intensity factors for semielliptical surface cracks in cylinders was implemented in pressurized thermal-shock (PTS) analyses. Subcontractors continued studies on crack arrest, cleavage fracture initiation, and cleavage transition. Specimens of the ORNL single-wire cladding were fabricated for irradiation. Pretest analyses were carried out for the upcoming thermal-shock test, TSE-7, and posttest analyses and examinations were under way for intermediate vessel test ITV-8A. Preparations for the first PTS experiment continued with design, procurement, and construction of the test facility, test vessels, and experimental apparatus.
