Management Status and Outlook on Thermal Aging of Cast Austenitic Stainless Steels Used in Primary Coolant Pipes of Nuclear Power Plant
摘要
Abstract
For the aging management of nuclear power plants,the structural integrity of the cast austenitic stainless steel base metal and welds of the primary coolant pipes is essential to the safe operation.The primary pipes face the problem of thermal aging after long-time operation,which requires effective management methods.This article comprehensively introduces the international and domestic engineering management status of the primary pipes for thermal aging.The difficulties and shortcomings in the actual management process of the pipes are summarized.Combining non-destructive testing methods and research status,the future direction is proposed.Effective management is achieved through thermal aging assessment and inspection for base materials and welds,which provides strong support for the safe service of primary pipes.关键词
