APPLICATION OF ENGINEERING METHODS ON REACTOR PRESSURE VESSEL INTEGRITY ASSESSMENT

摘要

An easy-to-use integrated program system for fast engineering integrity assessment is presented. It has been specially tailored for analyses of pressurised thermal shock loading of reactor pressure vessels. The applicability of the program system is demonstrated with an integrity evaluation of a cladded VVER-440 type reactor pressure vessel under strip-like cooling. The results agree well with those of detailed finite element analyses at the deepest point of the crack.
