For Figures 2a and 2b tau (T) is defined as follows:*r ave -- 1"BA Bwhere:rA = 0.866 seconds, control rod average scram insertion time limit to notch 39 per Technical Specification 3.1.4.r, =O0672+i1.65 N1X(O.0 I6i=1n1=In = number of surveillance tests performed in cycleN, = number of active control rods measured in the it surveillance testz, = average scram time to notch 39 of all rods measured in the ihsurveillance testN 1 = total number of active rods measured in Specification 3.1.4.1IT 1.0 prior to performance of the initial scram time measurements for the cycle2. ARTS provides for power- and flow-dependent thermal limit adjustments and*multipliers, which allow for a more reliable administration of the MCPR thermallimit. The MCPR(P) curves are independent of EOC-RPT and scram time option,but are determined for other EOOS. The MCPR(P) limits for PROOS wereconverted to a K(P) consistent with the ARTS offrated limits. MCPR(F) isindependent of Scram Time Option and all EOOS.3. The Operating Limit MCPR values for TBVOOS and EOC-RPT Out ofService are higher (more limiting) than for the standard normal operation case, andare therefore specifically identified where appropriate (Figures 2a and 2b). TheOLMCPR values for all other analyzed EOOS transient events are bounded by theNormal Operation limits.4. EOR is the End of Rated exposure as defined in the Cycle Management Report.ycle 15Page 4 of 21 CO0-I 5NINE MILE PNT UNIT 2CORE OPERATING LIMITS REPORTREVISION 0, CYCLOFigure 2aOperating Limit MCPR(BOC to EOR-2816 MWd/ST)CLE.01.801.751.701.651.601.551.501.451.401.351.30(1,1.73)(1,1.63)(1,1.61)00.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9Tau1Page 5 of 21 C -15NINE MILE ONT UNIT 2CORE OPERATING LIMITS REPORTREVISION 0, CYCL950t(L7BEME.1.801.751.701.651.601.551.50Figure 2bOperating Limit MCPR(EOR-2816 MWd/ST to EOC)EOC-RPT INormal Operation (0,1.38)(1,1.63)(1,1.62)1.451.401.351.3000.1 0.20.3 0.4 0.5 0.60.7 0.8 0.91Ta uPage 6 of 21 C.2-15NINE MILEONT UNIT 2CORE OPERATING LIMITS REPORTREVISION 0, CYC*5Figure 2cMCPR(P) for <26%Power,
