REQUEST FOR ADDITIONAL INFORMATION ISSUES RELATED TO THE LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATIONS - SINGLE LOOP OPERATION (SLO) SAFETY LIMIT MINIMUM CRITICAL POWER RATIO (SLMCPR) VALUE COOPER NUCLEAR STATION DOCKET NO. 50-298 1.
On Page 2 in Attachment 1, and on Page 4 of Enclosure 1 of your March 8, 2005 submittal, you state the reason for the increase in your SLO SLMCPR as The actual end of Cycle 22 exposure was 360 MWd/ST less than the licensing assumption and below the minimum exposure window specified in the reload licensing analysis. On Page 6 of Enclosure 1 in Table 1 you state that the Cycle Exposure at Limiting Point (Mwd/ST) is 11000 for the RLP (Reference Loading Pattern - original reload licensing basis) and 11350 for the CMR (Cycle Management Report - reanalyzed results based on the actual end of Cycle 22 exposure). These values are in contradiction to your statement that the actual end of Cycle 22 exposure was 360 MWd/ST less than the licensing assumption. Please explain this discrepancy.
2.
For Table 2a in Enclosure 1 of your submittal, indicate whether the values listed for Cycle 23 are Cycle Management Report (CMR) or Reference Loading Pattern (RLP) calculations. Are there any differences between the two?
