-1.0.' Core Operating Limits Report This Core Operating Limits Report for Cycle 14 has been prepared in accordance with the requirements of Technical Specification 6.11.2. The core operating limits have been developed using NRC-approved method-.
j ology (Ref.1) and are documented in References 2 and 3. The Cycle 14 values for the core operating limits are provided in Section 3.0 of this report.

l
- a. LThe MAPLHGR for each fuel type as a function of average planar exposure shall not exceed the limiting value shown in Figures 1-5 multiplied by the smaller of the two MAPFAC factors determined from Figures 6 and 7.
. b.. During SLO, the actual MAPLHGR for each type of fuel as a.
function of average planar exposure shall not exceed the limiting i
value shown in Figures 1-5 multiplied by the smaller of the two l
MAPFAC factors determined from Figures 7 and 8.
c.
Tables 1-5 provide the MAPLHGR values (KW/ft) for the exposure points (GWd/ST) used in the SAFER /GESTR-LOCA analysis.

Linear Heat Generation Rate (LHGR) - TS 3.12.B.
l l
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 l
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 1
type *, and scram time (Tau).. For core thermal power greater than j
or equal to 25% of rated and less than 30% of rated (25% s P <
j 30%), the Operating Limit MCPR is given by Figure 9. For core H
thermal power greater than or equal to 30% of rated (P 2 30%),
the Operating Limit MCPR is the greater of either:
i) The applicable flow-dependent MCPR determined from j
Figure 10, or li) The appropriate RATED POWER MCPR from Figure 11 multiplied by the applicable power-dependent MCPR multiplier determined from Figure 9.
1 i
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.
Cycle 14 MCPR limits are applicable to all DAEC fuel types.
