AND
SUMMARY
This report provides the Average Planar Linear Heat Generation Rate (APLHGR) limits, the Mnimum Critical Power Ratio (MCPR) limits, the Linear Heat Generation Rate (LHGR) limits and the Power to Flow Map for WNP-2, Cycle 14 as required by Technical Specification 5.6.5.
As required by Technical Specification 5.6.5, these limits were determined using NRC-approved methodology and are established so that all applicable limits of the plant safety analysis are met.
References 6.1, 6.2, 6.3, and 6.6 describe the LOCA analysis for rated power.
The analysis was performed with a methodology that results in Single Loop Operation APLHGR limits as well as Two Loop Operation MAPLHGR LIMITS.
The thermal limits for fuel given in this report are documented in the "WNP-2 Cycle 14 Reload Report" (Reference 6.3), the "WNP-2 Cycle 14 Transien'. Analysis Report" (Reference 6.4), Reference 6.5, Reference 6.7, and Reference 6.8.
The basis for power to flow map which addresses the instability operating region limits is documented in Reference 6.3.
The MCPR limit is the maximum of (a) the applicable exposure dependent, full power and full flow MCPR limit, (b) the applicable exposure and power dependent MCPR limit, and (c) the applicable flow dependent MCPR limitspecified in this report. This stipulation assures that the safety limit MCPR will not be violated throughout the WNP-2 operating regime.
Full power MCPR limits are specified to define operating limits at rated power and flow.
Power dependent MCPR limits are specified to define operating limits at other than rated power conditions. A flow dependent MCPR is specified to define operating limits at other than rated flow conditions.
The reduced 'flow MCPR limit, set by the limiting Recirculation Flow Increase event, provides bounding protection for all events at reduced flow.
The reload licensing analyses for this cycle provide operating limits for Extended Load Line Limit Analysis (ELLLA) operation which extends the power and flow operating regime for WNP-2 up to the 108% rod line which at full power corresponds to 88% of rated flow. The MCPR limits defined in this report are applicable up to 100% of rated thermal power along and below the 108% rod line.
The minimum flow for operation at rated power is 88% of rated flow; the maximum is 106%.
Preparation, review, and approval of this report were performed in accordance with applicable Supply System procedures.
The specific topical report revisions and supplements which describe the methodology utilized in this cycle specific analysis are referenced in Technical Specification 5.6.5.

3.0 MINIMUMCRITICALPOWER RATIO MCPR LIMITFOR USE IN TECHNICAL SPECIFICATION 3.2.2 The MCPR limit for use in Technical Specification 3.2.2 shall be greater than or equal to the bounding limits determined from Table 3.1a, Table 3.1b, Table 3.2a, Table 3.2b and Figures 3.1 through 3.34.
For the purposes of cycle extension, the feedwater temperature entering the reactor vessel shall not be reduced to less than 355'F.
The MCPR limits given apply to both two loop and single loop operation.
The MCPR safety limit for SPC 9x9-9X is 1.13 for two loop operation and 1.14 for single loop operation.
Note:
ATRIUM-9Xand SPC 9x9-9X are equivalent terms for the same fuel type and may be used interchangeably.
The MCPR safety limit for SVEA-96 is 1.07 for two loop operation and 1.09 for single loop operation.
The MCPR safety limits are applicable to Cycle 14 only.

Notes for Tables 3. la, 3.1b, 3.2a, and 3.2b Note 1:
The scram insertion times must meet the requirements of Technical Specification 3.1.4, The NSS MCPR values are based on the ABB transient analysis performed using the control rod insertion times shown below (defined as normal scram speed:
NSS).
In the event that SRs 3.1.4.1, 3.1.4.2, 3.1.4.3 and 3.1.4.4 show the NSS insertion times have been exceeded, the MCPR limit shall be determined from the applicable Technical Specification Scram Speed (TSSS) MCPR limits in Tables 3.1a, 3.1b, 3.2a, and 3.2b.
The NSS and TSSS MCPR limits include up to eight declared "slow" rods.
Position Inserted From Fully Withdrawn Notch 45 Notch 39 Notch 25 Notch 5 Slowest measured average control rod insertion times (seconds) to specified notches for all operable control rods for each group of four control rods arranged in a two-by-two array.
(Excluding rods which have been declared "slow" and that meet the "slow" control rod se aration criteria.)
0.430 0.720 1.600 2.950 Note 2:
Note 3:
For Single Loop Operation (SLO), the 9x9-9x SLMCPR increases by 0.01 and the SVEA-96 SLMCPR increases by 0.02. The increases are included in the MCPR operating limits.
e For the noted full power MCPR limits, the Rod Withdrawal Error (RWE) event is limiting.
When turbine bypass is
- operable, the Generator Load Rejection No Bypass (GLRNB) event-is limiting for the full power limits.
When turbine bypass is inoperable, the Feedwater Controller Failure No Bypass (FWCFNB) event is limiting for the full power limits.
The RWE analysis was performed with a nominal Rod Block Monitor (RBM) setpoint of 1.06.
Note 4:
Note 5:
Flow dependent MCPRs are not applicable for SLO.
Power dependent MCPR limits are provided for core thermal powers greater than or equal to 25
% of rated power at all core flows.
The power dependent MCPR limits for core thermal powers less than or equal to 30% of rated power are subdivided by core flow.
Limits are provided for core flows greater than 50% of rated flow and less than or equal to 50% of rated flow, respectively.
A step change in the power dependent MCPR limits,occurs at 30% of rated power because direct scram on turbine throttle valve closure is automatically bypassed below 30% of rated power and not applicable per Technical Specification 3.3.1.1.
