这份报告更新和取代了NRC在NUREG-0313中确立的技术立场，该报告于1977年7月出版，名为《沸水堆冷却剂压力边界管道材料选择和加工指南的技术报告》，随后于1980年7月出版。这份报告阐述了NRC工作人员修订后的可接受的方法，以控制BWR ASME规范1、2和3类压力边界管道和安全端的晶间应力腐蚀开裂敏感性。对于不完全符合本文件材料选择、测试和加工指南组合的管道，将需要根据10 CFR 50.55a(G)(6)(Ii)进行不同程度的在役加强检查。这一修订还包括关于裂纹评估和焊接层修复方法的指南，用于长期运行或工厂的持续临时运行，直到实施更永久的解决方案。
This report updates and supersedes the technical positions NRC established in NUREG-0313, ''Technical Report on Material Selection and Processing Guidelines for BWR Coolant Pressure Boundary Piping,'' published in July 1977, and its subsequent revision published in July 1980. This report sets forth the NRC staff's revised acceptable methods to control the intergranular stress corrosion cracking susceptibility of BWR ASME Code Class 1, 2, and 3 pressure boundary piping and safe ends. For piping that does not fully comply with the material selection, testing, and processing guideline combinations of this document, varying degrees of augmented inservice inspection will be required, pursuant to 10 CFR 50.55a(g)(6)(ii). This revision also includes guidance regarding crack evaluation and weld overlay repair methods for long term operation or for continuing interim operation of plants until a more permanent solution is implemented.
