因为股份公司一份SHR程序第二版写的我的名字编制，不少群厂同事找我问SHR指标解释给他们公司质保，说他们公司程序符合股份公司程序标准。其实和第一版（屈工结合群厂实践编制，所以第二版其实我只是到了升版时间走了个升版流程，修改了不到50个字?，当时定位就是结合各电厂成熟做法总结成股份标准，其它程序也如此，要不各电厂涉及业务成熟度不一，没办法按照行业最佳实践写。这几年开始鼓励部分电厂具备条件先行先试，可以不用遵守股份标准，具备条件群厂推广再升版股份标准，这个给优秀电厂提供了发挥空间）没有实质性区别，只修改了LCO这些小细节，里面的指标基本上都是2006年DYB引入SHR的指标，当时没做的工作比较多，如设备分级只有CCM，没有C级，没有开展MR，很多指标估计就结合当时电厂实际情况做了“缩水”的处理了，当时引入SHR是DYB非常先进的做法了，即使指标缩水也是当时在国内核电行业先进的做法，20年过去了，设备可靠性管理913部分电厂已全面实施，分级已经有C级清单，系统监督部分电厂也实施应用，MR和MSPI也都实施了很久，SHR指标还是原来的就有点不太合适了，条件具备了，需要做个升级优化了，结合国外核电行业设备可靠性工作组的建议，总结出来行业SHR指标最佳实践分享大家，为避免翻译歧义，原文发出来供大家参考，后续SNPI也会推动股份公司程序做SHR指标升版。
