ice inspection (ISI) program, and the proposed ISI program should follow the recommendations given in Regulatory Guide 1.83. The steam generators should be designed to permit inspection of every tube. The tube examination equipment and procedures should be capable of detecting and locating defects with a penetration of 20%. or more of the wall thickness. A permanent record of test data should be provided. A baseline tube inspection should be scheduled prior to startup. The sample selection and testing of tubes, the inspection intervals, the actions to be taken if defects are identified, and reporting requirements should follow the recommendations in the applicable Standard Technical Specifications. III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. He determines that the design of the steam generators, as described in the PSAR, will permit access for the specified inspection techniques. He also evaluates the design of the steam generator as described in the FSAR and the Technical Specification inservice inspection program to determine the degree to which the recommenda- tions of Regulatory Guide 1.83 have been followed. He determines that the inspection techniques for the tubes, the selected number of tube samples, the inspection intervals, and the actions to be taken in the event defects are observed are in accordance with the positions stated in the regulatory guide and applicable NUREG. He determines that a baseline inspection will be made prior to startup of the plant. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided in accord- ance with the requirements of this SRP section, and that his evaluation supports conclusions of the following type, to be included in the staff's safety evalua- tion report: To ensure that no deleterious defects develop during service, steam generator tubes will be inspected prior to plant
