Content:
ys and the emergency core cooling water following a 6.1.1-14 Revision 2 - March 2007 loss-of-coolant or design-basis accident are adequate to reduce the probability of stress corrosion cracking of the austenitic stainless steel components and welds of the engineered safety features systems in containment throughout the duration of the postulated accident to completion of cleanup. Also, the control of the pH of the sprays and cooling water, in conjunction with controls on selection of containment materials, is in accordance with RG 1.7, “Control of Combustible Gas Concentrations in Containment Following a Loss-of-Coolant Accident,” and provides assurance that the sprays and cooling water will not give rise to excessive hydrogen gas evolution resulting from corrosion of containment metal or cause serious deterioration of the materials in containment. The controls placed upon component and system cleaning are in accordance with RG 1.37, “Quality Assurance Requirements for Cleaning of Fluid Systems and Associated Components of Water-Cooled Nuclear Power Plants,” and provide a basis for the finding that the components and systems have been protected against damage or deterioration by contaminants as stated in the cleaning requirements of 10 CFR Part 50, Appendix B. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with
