include References 9, 1114, 3115, 2116, 3518, 3219, and 78 3620 , and they should all be appropriately cited in the plant safety evaluation report. 79 Applicable Regulatory Guides (References. 67-13, 22, 28-30, and 41 ) should also be 80 81 mentioned in the plant safety evaluation reports. Deviation from these guides or positions should be explained. After briefly discussing related previous reviews, the plant safety evaluation should concentrate on areas where the application is not identical to previously reviewed and approved applications and areas related to newly discovered problems. Analytical predictions discussed in Subsection II.C.3 will be reviewed in PSARs, FSARs, or licensing topical reports. The validity of analytical models used to predict the performance of the fuel system design, and their applicability up to the design's specified burnup limit, should be reviewed. Fuel burnup limits should be specified for each fuel type used in the reactor and justified based on irradiated material properties data and prototypic test results. An exception may be made for prototype test assemblies—in which case only an estimate of the maximum burnup need be provided. When the methods are being reviewed, calculations by the staff may 82 be performed to verify the adequacy of the analytical methods. Thereafter, audit calculations will not usually be performed to check the results of an approved method that has been submitted in a Safety Analysis Report. Calculations, benchmarking exercises, and additional reviews of generic methods may be undertaken, however, at any time the clear need arises to reconfirm the adequacy of the method. For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface
