them Is not required. The standard review plan sections are keyed to the Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants. Not all sections of the Standard Format have a corresponding review plan. Published standard review plans will be revised periodically. as appropriate, to accommodate comments and to reflect new Informa- tion and experience. Comments end suggestions for Improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission. Office of Nuclear Reactor Regulation. Washington. D.C 20555 II. ACCEPTANCE CRITERIA The acceptance criteria for this SRP section are as follows: 1. General Design Criterion 13 (Ref. 1) as it relates to instrumentation and controls provided to monitor variables over anticipated ranges for normal operations, anticipated operational occurrences, and for accident conditions. 2. 10 CFR Part 100 (Ref. 2) as it relates to offsite consequences resulting from reactor operations with an undetected misloaded fuel assembly. The primary safeguards against fuel loading errors are procedures and design features to minimize the likelihood of the event. Additional safeguards include incore instrumentation systems which would detect errors. However, should an error be made and go undetected, it is possible in. some reactor designs for fuel rod failure limits to be exceeded. Therefore, the following acceptance criteria are necessary to cover the event of operation with misloaded fuel caused by loading errors: a. To meet the requirements of GDC 13, plant operating procedures should include a provision requiring that reactor instrumentation be used to search for potential fuel loading errors after fueling operations. b. In the event the error is not detectable by the instrumentation system and fuel rod failure limits could be exceeded during normal operation, the offsite consequences should be a small fraction of the 10 CFR Part 100 guidelines.
