welds. 8. Code Exemptions. The exemptions from Code examination requirements identified by the applicant are acceptable if they have been permitted by Subsubarticles IWC-1220 or IWD-1220 of Section XI of the ASME Code. 9. Relief Requests. Request for relief from the ASME Code Section XI examination requirements that are found to be impractical due to the limitations of design, geometry, or materials of construction of components are evaluated in accordance with 10 CFR 50.55a. 10. Code Cases. The exemptions from Code examination requirements identified by the applicant or licensee are acceptable if they have been permitted by appropriate ASME code cases. 11. Operational Programs. For COL reviews, the description of the operational program and proposed implementation milestones for the Preservice Inspection and Inservice Inspection and testing programs for Class 2 and 3 components are reviewed in accordance with the requirements of 10 CFR 50.55a, “Codes and Standards.” The implementation milestone for the inservice inspection program is when the plant enters into commercial operation. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. 10 CFR 50.55a, "Codes and Standards," requires, in paragraph (a)(1), that structures, systems, and components (SSCs) be designed, fabricated, erected, constructed, tested, inspected, and maintained to quality standards commensurate with the importance of the safety function they are intended to perform. 10 CFR 50.55a(b) incorporates, by reference, the ASME Boiler and Pressure Vessel Code. Throughout the service life of a boiling or pressurized water cooled nuclear power reactor, its Code Class 2 and Class 3 systems and components must meet the requirements of Section XI of the ASME Boiler and Pressure Vessel Code. 10 CFR 50.55a(g) addresses inservice inspection requirements. Section XI defines, for
