Content:
ariables identified in Regulatory Guide 1.97 for which the alternative instrumentation is proposed. Revision 4 of Regulatory Guide 1.97 does not identify specific variables to be displayed; therefore, this topic does not apply to Revision 4. Guidance for Boiling Water Reactor (BWR) and Pressurized Water Reactor (PWR) Variables Table 1, BWR Variables, and Table 2, PWR Variables, of Regulatory Guide 1.97, Revision 2, and Table 2, BWR Variables, and Table 3, PWR Variables, of Regulatory Guide 1.97, Revision 3, identify guidelines for the range, design/qualification category, and purpose for specific BWR and PWR variables. For selected BWR and PWR variables identified in the tables, acceptable deviations or clarifications are identified in Tables 1 and 2, respectively, of this BTP. Tables 1 and 2 of this BTP list Regulatory Guide 1.97 variables and types of deviations from Regulatory Guide 1.97 guidelines (e.g., deviations with respect to category, redundancy, range, direct measurement), and provide a summary of the acceptance guidelines or clarification associated with the deviations. BTP 7-10-6 Revision 5 - March 2007 Revision 4 of Regulatory Guide 1.97 does not identify specific variables; therefore Tables 1 and 2 of this BTP do not apply to Revision 4. Conversion to Revision 4 Applicants/licensees of reactors that are committed to either Revision 2 or 3 of Regulatory Guide 1.97 may voluntarily convert the plant's entire accident monitoring program to the criteria of Revision 4 of Regulatory Guide 1.97. Conversion means revising the commitment for the plant's entire accident monitoring program from the current licensing basis (either Revision 2 or 3) to the guidance in Revision 4. The conversion to Revision 4 could include physical changes (e.g., replacing an instrument), licensing changes (e.g., technical specification changes), changes in variable types and associated design and qualification criteria, changes in the function or purpose of the variable, and changes
