Heavy-Section Steel Technology Program Quarterly Progress Report for October-December 1980
- Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
The investigation focuses on the behavior and structural integrity of steel pressure vessels containing cracklike flaws. Current work is organized into five tasks: (1) program administration and procurement, (2) fracture mechanics analyses and investigations, (3) investigations of irradiated materials, (4) thermal shock investigations, and (5) pressure vessel investigations. A finite-element computer program is operational for direct calculation of stress-intensity factors of surface flaws in cylinders, nozzle corners, and plates. Studies of ductile-brittle transition in fracture are continuing. Irradiation of one capsule in the Fourth HSST Irradiation Series was completed, and irradiation of the second capsule is continuing. Posttest analysis of thermal shock experiment TSE-5A indicates that all major objectives were attained. Properties of the trial weld for intermediate test vessel V-8A were satisfactory, and preparations for the vessel test were continued. Studies of pressurized-thermal-shock testing concepts are proceeding.
