ain, and/or protect barriers against the release of fission products. Application of special process control requirements provides assurance that implementation of special processes will not introduce conditions adverse to quality in ESF systems, including, but not limited to, damage or deterioration 6.1.1-10 Revision 2 - March 2007 of ESF and/or RCPB materials and pressure boundaries, alteration of critical material properties, acceleration of effects associated with aging, flow blockages in ESF systems, or increases in the susceptibility to failure mechanisms such as stress corrosion cracking. This reduces the likelihood of degradation and/or failure of the ESFs that could cause substantial reduction in the capabilities of fission product barriers. Criterion XIII of Appendix B to 10 CFR Part 50 requires that measures be established to control the cleaning of material and equipment to prevent damage or deterioration. Application of cleaning requirements to the ESF materials provides assurance that contaminants to which they could be exposed will not damage or deteriorate the materials, alter their properties, accelerate effects associated with aging, or increase the susceptibility to failure mechanisms such as stress corrosion cracking. This reduces the likelihood of degradation and/or failure of the ESFs that could cause substantial reduction in the capabilities of fission product barriers. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. Materials and Fabrication A. Material Specifications. The reviewer verifies that the materials proposed for the ESF are in
