Results of low ductile shelf intermediate vessel test V-8A. [PWR]

Conference ·
OSTI ID:6736653

Intermediate test vessel V-8A was pressure tested hydraulically at 150/sup 0/C on August 11, 1982, in the twelfth test of a flawed 152-mm-thick steel vessel. The purpose of the test was to investigate the tearing behavior of material having low upper-shelf toughness similar to the toughness of irradiated high-copper seam welds in some existing reactor pressure vessels. A primary objective of the test was to induce and interrupt a tearing instability so as to obtain experimental data by which the application of methods of elastic-plastic fracture mechanics to large structures could be evaluated. This objective was attained. Posttest examinations and evaluations of data are progressing. A preliminary assessment of results is presented.
