Content:
uding, but not limited to, damage or deterioration 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 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. Appendix B of 10 CFR Part 50 also requires, in Criterion XIII, that measures be established to control the cleaning of material and equipment to prevent damage or DRAFT Rev. 2 - April 1996 6.1.1-12 deterioration. ESF functions include emergency core cooling, reactivity control, fission product containment, and heat removal to an ultimate heat sink. These functions are provided to establish, maintain, and/or protect barriers against the release of fission products. 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 and emphasize material from the procedures described below, as may be appropriate for a particular case. To ascertain that the acceptance criteria given in subsection II of this SRP sSection are met, the 68 reviewer examines each of the review areas given in subsection I of this SRP section for the required information, using the following procedure: A. Primary Review AreaMaterials and Fabrication69 1. Material Specifications The MTEB reviewer verifies that the materials proposed for the ESF are in conformance 70 with
