Enclosure REQUEST FOR ADDITIONAL INFORMATION RELATED TO OSCILLATION POWER RANGE MONITORS PERRY NUCLEAR PLANT, UNIT 1 DOCKET NO. 50-440 In reviewing the FirstEnergy Nuclear Operating Companys (FirstEnergy) July 5, 2005, (Agencywide Documents Access and Management System Accession Number ML051940205) request to modify Technical Specification (TS) Surveillance Requirement 3.3.1.3.5, the NRC staff has determined that the following information is needed in order to complete its review:
1.
On page 1 of the cover letter, the second paragraph states that the Perry Nuclear Plant, Unit 1 (Perry) is currently operating with the oscillation power range monitors enabled at
$ 23.8-percent rated thermal power. This is below the TS value of 28.6-percent rated thermal power. Please document the historical basis for the 23.8-percent rated thermal power value.
2.
On page 4 of Attachment 2, the fourth paragraph states that General Electric developed an analytical method which can be used to explain the interactive corrective action (ICA) and enabled regions. The methodology is called backup stability protection (BSP) analysis and is used to redraw the power to flow map. The BSP analysis uses plant-specific inputs to develop decay ratios. The decay ratios are then used to adjust the ICA regions in order to provide stability protection. Please summarize the Perry-specific applicability for decay ratio.
