1.0 Core Operating Limits Report This Core Operating Limits F
) ort for Cycle 15 has been prepared in accordance with the requirenm:nts of Technical Specification 6.11.2. The core operating limits have been developed using NRC-approved method-ology (Ref.1) and are documented in References 2,3,7, and 8. The Cycle 15 values for the core operating limits are provided in Section 3.0 of this report.

s 3.0 Core Operating Limits 1.
Maximum Average Planar Linear Heat Generation Rate (MAPLHGR)-
a.
The MAPLHGR for each fuel type as a function of average planar exposure shall not exceed the limiting value shown in Figures 1 -
and 2 multiplied by the smaller of the two MAPFAC factors dt ained from Figures 3 and 4.
b.
During SLO, the actual MAPLHGR for each type of fuel as a function of average planar v.xposure shall not exceed the limiting value shown in Figures 1 and 2 multiplied by the smaller of the two MAPFAC factors determined from Figures 4 and 5.
j i
c.
Tables 1 and 2 provide the MAPLHGR values (KW/ft) for the exposure points (GWd/ST) used in the SAFER /GESTR-LOCA l
analysis. Tables 1 and 2 correspond to Figures 1 and 2 respectively.
2.
Linear Heat Generation Rate (LHGR)- TS 3.12.B.
a.
The LHGR of any rod in any fuel assembly shall not exceed i
14.4 KW/ft.
3.
Minimum Critical Power Ratio (MCPR) -TS 3.12.C a.
The MCPR shall be equal to or greater than the Operating Limit MCPR, which is a function of core thermal power, core flow, fuel type *, and scram time (Tau). For core thermal power greater than or equal to 25% of rated and less than 30% of rated (25% < P <
30%), the Operating Limit MCPR is given by Figure 6. For core thermal power greater than or equal to 30% of rated (P > 30%),
the Operating Limit MCPR is the greater of either:
i) The applicable flow-dependent MCPR determined from Figure 7, or ii) The appropriate RATED POWER M'CPR from Figure 8
[ Figure 9 for Turbine Bypass Valves (TBVs) out-of-service; Figure 10 for the End-of-Cycle Recirculation Pump Trip J
(EOCRPT) out-of-service; or, Figure 11 for a combination of 1
TBVs and EOCRPT out-of-service), multiplied by the applicable j
power-dependent MCPR multiplier determined from Figure 6.

- b. During SLO with core thermal power greater than or equal to 25%
of rated, the SLO Operating Limit MCPR is determined by adding 0.03 to the Operating Limit MCPR determined above.
4 Cycle 15 MCPR limits are applicable to all DAEC fuel types.
