l 1.1 APPLICATION OF THIS APPENDIX
- a. This Appendix applies to protective coatings and their application to surfaces for Cc=anche Peak Steam Electric Statien as listed in ANSI N101.2 and ce= prise requirements applicable to Class I coating service level for the nuclear reacter containment facilities.
- b. Class I coating service level applies to syste=s and cc=penents of nuclear facilities within the reactor containment building which are essential (1) to prevent postulated accidents which could affect the public health and safety er (2) to mitigate the consequences of these accidents. The quality assurance for Class I service level shall confer = to the requirements of this standard.
- c. Because of the i= practicality of imposing all the requirements of this appendix on specific items (requiring enly a s=all quality of coating material), the Owner, censistent with his Quality Assurance Program, will accept affidavits of certification from vendors attesting to the
! quality for a shop or field coating. Section 6.10 sets forth requirements to for this noncenfermance.

SOLUTION: If coating failed from these areas it would do so in a sporadic manner L and involve only minute amounts of coatings. Gross coating failure causing , clogging of the Containment scray pumos from these areas is not likely. Coatings extending into open tube steel members resulting from spray coerations performed (.
