.h;-l Imster Rogers. Director of Eagulatory Standards John F. O' Leary, Director of Licensing AFFLICABILITY OF 10 CFR 50 APFEEDIX B Our field inspection experience has identified a situation involving standards and the application of standards which should be corrected.
We have found that the designation of systems, components and structures to which 10 CFR 50 Appendix B apply, varias widaly from reactor site to reactor site, for similar facilities. This situation
' mads to confusion for our field personnel and leaves as in a waak position relative to obtaining corrective action.
The systems, components and structures to which Appendix B of 1D CFR 50 are to be applied are delineated in the PSAR and FSAR for each facility. We find that the lists of systems, compr==ah, and structures are not consistent, in that they vary greatly for ~
similar type facilities. Safety Guida 26
'! Quality Group Classifications and Standards," and Safety Guide 29 "Seisuie Design Classification," give some guidance, however, they refer to 10 CFR 50 Appendix A, " General Design Criteria for Nuclear Power Flants," and not 10 CFR 50 AppenM r B. " Quality Assurance for Nuclear Power Flants." Therefore, there is nothing that requires the utility to fabricate and install these systens in accordance with Appendix B requirements, unless they are listed in the FSAR -
FSAR as a Class I systen or sturcture.
We request that the following action be taken l.
The Safety Guides, where applicable, be tied back to AppenMr B of 10 CFR 50.
2.
The utilities be required to reference the applicable Safety Guides in the PSAR and FSAR.
3.
Establish review standards to assure that all Class I systems and structures are uniformly listed or referenced to Safety Guides in the PSAR - FSAR for similar facilities.
