Content:
ssure testing and VT-2 examinations are also to be performed on non-Code safety-significant piping. The non-Code safety-significant piping will be treated as ASME Code Class piping for the purposes of examination and pressure testing. k. Examination methods, equipment qualification, personnel qualification, and procedure qualification are to be in accordance with the edition and addenda of the ASME BPV Code endorsed by the NRC in 10 CFR 50.55a. l. Acceptance standards for identified flaws and repair or replacement activities are to be performed in accordance with the ASME BPV Code, Section XI requirements. m. Records and reports should be prepared and maintained in accordance with the ASME BPV Code, Section XI, edition and addenda as specified in the licensee’s ISI program. RG 1.178, Page 23 4. Element 4: Documentation The sections below present the recommended contents for a plant-specific RI-ISI submittal. This guidance will help ensure the completeness of the information provided and aid in minimizing the time needed for the review process. 4.1 Licensee’s Risk-Informed Inservice Inspection Submittal Documentation References to NRC-approved topical reports that address the methodology and issues requested in a submittal are acceptable. Documentation guidelines specified in approved topical reports may be considered instead of the following guidelines when the methodology from an approved topical report is used. Since topical reports could cover more issues than applied by a licensee, or the licensee may elect to deviate from the full body of issues addressed in the topical report, such distinctions should be clearly stated. The application to implement an RI-ISI program should include the following items: a. Make a request to implement an RI-ISI program as an authorized alternative to the current NRC-endorsed ASME BPV Code under 10 CFR 50.55a(z)(1). The licensee should also describe how the proposed change impacts any commitments made to the NRC. b. Discuss
