ptance Standards," and 47 48 IWD-3000, "Acceptance Standards."49 c. The methods, procedures and requirements regarding qualification of personnel performing ultrasonic examination reflect the guidance provided in Appendix VII to Division 1 of Section XI of the ASME Code.50 4. Inspection Intervals The inservice inspection program schedule given in the SAR is acceptable if the required examinations and pressure tests are completed during each ten year interval, hereinafter 51 designated as the inspection interval, and as required by Articles IWA-2000, IWC-2000, and IWD-2000 of Section XI. 52 5. Evaluation of Examination Results The methods for evaluation of examination results are reviewed for compliance with Articles IWC-3000 and IWD-3000 in the Code. If the applicable edition of the Code DRAFT Rev. 2 - April 1996 6.6-6 states that these articles are in the course of preparation, the rules of Article IWB-3000 53 shall apply. The repair procedures are acceptable if in compliance with Article IWA-4000, "Repair Procedures," of Section XI.54 6. System Pressure Tests The SAR program for Class 2 and 3 system pressure testing is acceptable if it meets the criteria of Articles IWC-5000, "System Pressure Tests," and IWD-5000, "System 55 56 Pressure Tests," of Section XI. 57 7. Augmented ISI to Protect Against Postulated Piping Failures High-energy fluid system piping between containment isolation valves should receive an augmented ISI as follows: a. Protective measures, structures, and guard pipes should not prevent the access required to conduct the inservice examinations specified in the Code, Section XI, Division 1. b. For those portions of high energy fluid system piping between containment isolation valves, the extent of inservice examination completed during each inspection interval should provide 100% volumetric examination of circumferential and longitudinal pipe welds within the boundary of these portions of piping. c. For those portions of high-energy fluid system
