Evaluation of the Preirradiation Baseline Material Characteristics for Yonggwang Nuclear Reactor Pressure Vessel
영광 원자력 발전소 원자로 소재의 가동전 재료 물성 특성
Abstract
Nuclear reactor pressure vessel should be safety even in the case that hypothetical defects with allowable size are in vessel. Therefore, the materials should have excellent fracture resistance characteristics. The purpose of this study is to analyze the results of preirradiation baseline test of nuclear pressure vessel for Yonggwang Unit 5/6. In experiments, drop weight tests and impact tests are carried out to obtain nil-ductility transition reference temperature,
