Current work is organized into six tasks: (1) program adminstration and procurement, (2) fracture mechanics analyses and investigations, (3) investigations of irradiated materials, (4) thermal-shock investigations, (5) pressure vessel investigations, and (6) stainless steel cladding investigations. The three-dimensional finite-element program for elastic-plastic fracture mechanics was used with a deformation plasticity model on test vessel analysis. Subcontractors analyzed the last thermal-shock experiment and continued development of a standard procedure for crack-arrest toughness testing and investigation of transition from cleavage to fibrous fracture. Work progressed toward initial testing of specimens in the Fourth HSST Irradiation Series. Parametric analysis of overcooling accidents was completed, and improvements to the OCA-I code were made. Intermediate test vessel V-8A was flawed and is in preparation for testing. A major part of the design of a pressurized-thermal-shock test facility was completed. Test equipment and specimens were prepared for clad plate fracture tests.
