RPV用钢美国常用断裂韧性KIC表达式的对比分析
Compare and Analysis on Experiential Expression of USA RPV Steel Fracture Toughness K IC
摘要
Abstract
To assess the integrity of Reactor Pressure Vesse( RPV) after irradiation, several experiential expressions between RPV steel fracture toughness and temperature were suggested. Basing on the fracture toughness testing data of ORNL, these experiential expressions were compared and analyzed. It showed that adjusted ASME K ICcurve is the most conservative one. The ASME KICcurve has enough conservative in high T-Tref region, but less conservative in low T - T ref region. 5% lower bound of master curve is conservative enough. ASME Code Case N631 is as conservative as ASME K IC curve.关键词
