nd preventive measures promptly taken to preclude potential loss of reactor coolant or impairment of reactor core cooling. 2. According to10 CFR 50.55a, "Codes and Standards," structures, systems, and components (SSCs) must be designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with the importance of the safety function they are intended to perform. Section 50.55a incorporates by reference Section XI of the ASME Boiler and Pressure Vessel Code. Section XI defines, for each Code Class, the intervals between inservice inspections, the scope of the inspection activity, the inspection sample, the sample selection methodology, the method of inspection, the acceptance criteria for various types and sizes of material flaws identified during the inspection, and various other related technical details required for properly performing the inservice inspection activity. Additionally, the recommendations in Regulatory Guide 1.150 apply as specified in Subsection II.3.E of the SRP Acceptance Criteria of this SRP section. Performing a periodic inspection program based on the requirements of 10 5.2.4-8 Revision 2 - March 2007 CFR 50.55a and ASME Code Section XI, as supplemented with the guidance in Regulatory Guide 1.150, is the means of maintaining the structural integrity of the RCPB at a level of reliability comparable to that at which it was initially installed and of ensuring the structural and leak-tight integrity of the RCPB. 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. System Boundary Subject to Inspection. The
