that a code requirement is impractical due to the limitations of design, geometry, or materials of construction. IV. EVALUATION FINDINGS The reviewer verifies that adequate information is provided in accordance with the requirements of this SRP section, and that his evaluation supports conclu- sions of the following type, to be included in the staff's safety evaluation report: To ensure that no deleterious defects develop during service, selected welds and weld heat-affected zones will be inspected prior to plant startup and periodically throughout the life of of the plant. The applicant (licensee) has stated that his inservice inspection (ISI) program will comply (complies) with the rules published in 10 CFR Part 50, Section 50.55a. The design of the reactor coolant system incorporates provisions for access for inservice inspection in accord- ance with Section XI of the ASME Boiler and Pressure Vessel Code, ( ) Edition, including Addenda through the ( ) Addenda. Suitable equip- ment will be (has been) developed and installed to facilitate the remote inspection of these areas of the reactor coolant pressure bound- ary that are not readily accessible to inspection personnel. The ISI program will consist of a preservice inspection plan and an inservice inspection plan. The conduct of periodic inspections and leakage and hydrostatic testing of pressure-retaining components of the reactor coolant pressure boundary in accordance with the requirements of Section XI of the ASME Code provides reasonable assurance that evidence of structural degradation or loss of leaktight-integrity occurring during service will be detected in time to permit correc- tive action before the safety function of a component is compromised. Compliance with the inservice inspections required by this Code con- stitutes an acceptable basis for satisfying in part the requirements of General Design Criterion 32. The staff concludes that the inservice program is acceptable and.meets the inspection and
