y. If the basic criteria are not followed, either intentionally or through error, the reviewer must evaluate, on a case basis, whether the integrity 5.3.3-4 Rev. 1 - July 1981 of the reactor vessel is compromised, using current technology, past practice, and experience as applicable. 6. Operating Conditions Acceptance criteria for operating limits for the reactor vessel, and the regulations that they satisfy, are detailed in SRP Section 5.3.2, "Pressure-Temperature Limits." These acceptance criteria are given in Appendix G, "Fracture Toughness Requirements," to 10 CFR Part 50. The criterion for acceptable behavior is that the vessel must remain leaktight enough to support adequate core cooling. The generally accepted principles and procedures of linear elastic fracture mechanics provide the basis for acceptance of analyses that support conformance with this criterion. 7. Inservice Surveillance The acceptance criteria for adequacy of the reactor vessel materials surveillance program, and the regulations satisfied by the criteria, are detailed in SRP Section 5.3.1. The criteria are based on the require- ments of Appendix H, "Reactor Vessel Material Surveillance Program Requirements," to 10 CFR Part 50. The SAR also provides information regarding the inservice inspections to be performed on the reactor vessel. The acceptance criteria for accessi- bility and inspection plan details, and the regulations that they satisfy, are detailed in Standard Review Plan Section 5.2.4, "Reactor Coolant Pressure Boundary Inservice Inspection and Testing." These criteria are those of Section XI of the Code. II. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. The reviewer initially determines that the basic criteria are met in each review area covered by this SRP section. Although he will not normally be responsible for the basic reviews of all of these areas, he will consult with those
