Abstract

Repaired Motors for Nuclear Power Plants require that: (1) adequate controls and traceability exist for motor repair, (2) operability is not degraded by the repair, (3) special nuclear capable materials are used when required, (4) appropriate consideration be given to the driven load requirements, and (5) s ecial adequacy and performance testin is compreted demonstrating suitability, especiah y for Nuclear Safety Related service subsequent to repair. An evolving consensus of “good practice” is developing based on industr experience feedback, guidance from IEEE standards development, EPRI research, and the Electric Apparatus Service Association practices. Adequacy re uires careful attention to Commercial %rade Item Dedication, Qualification, and Quality Processes. This paper presents various considerations for motor inspection, assessment, material procurement, documentation, repair, determination of critical characteristics, and testin to allow retention or enhancement of original fesign qualification and demonstrated capability for the motor being repaired.

保证核电站电机维修的充分性

核电厂的维修电机要求:(1)对电机维修有足够的控制和可追溯性，(2)不因修理而降低可操作性，(3)在需要时使用特殊的核性能材料，(4)适当考虑驱动负载要求，以及(5)完成了证明适用性的特殊充分性和性能测试，特别是对维修后的核安全相关服务。基于行业经验反馈、来自IEEE标准开发、EPRI研究和电气设备服务协会实践的指导，“良好实践”的共识正在不断发展。充足性要求仔细关注商业%级项目奉献，资格和质量过程。本文介绍了电机检查、评估、材料采购、文件、维修、关键特性确定和测试的各种考虑因素，以保留或增强原始设计资格和被修理电机的演示能力。
