4. General Information Oyster Creek is a non-ARTS plant. There are Oyster Creek specific flow-biased and power-biased MCPR operating limits for operation at less than rated flow and power. The flow-biased MCPR limits are discussed in Section 6.1. The power-biased MCPR limits are discussed in Section 6.2. Section 7 provides power-biased LHGR limits for PROOS operating condition and flow-biased LHGR limits for operation with one TBVOOS. Rated core flow is 61 Mlb/hr and operation up to 110.7% of rated is licensed for this cycle. Additionally, Oyster Creek utilizes an ELLLA operating domain, which has expanded the power/flow map to allow for greater operational flexibility.

5. Average Planar Linear Heat Generation Rate The MAPLHGR limits are discussed in Technical Specifications Section 3.10.A. The MAPLHGR limits for the lattices in each fuel type as a function of average planar exposure are given in Tables 5-1 through 5-22 for operation with zero ISOLATED RECIRCULATION LOOPS (Reference 2). For operation with one ISOLATED RECIRCULATION LOOP, multiply the limits in Tables 5-1 through 5-22 by the ISOLATED Loop multiplier listed in Table 5-23 (Reference 2). All lattices are defined in Appendix A.

6. Minimum Critical Power Ratio The MCPR limits are discussed in Technical Specifications Section 3.10.C. For all conditions, the more limiting of the flow adjusted MCPR and power adjusted MCPR is applied.

6.1. Manual Flow Control MCPR Limits The flow adjusted MCPR is determined by multiplying the applicable rated condition MCPR limit shown in Table 6-1 by the applicable MCPR multiplier, Kf, given in Table 6-2. Table 6-1 MCPR limits are the maximum values obtained from analysis of pressurization and non-pressurization events. MCPR values are determined by the cycle-specific fuel reload analyses in Reference 2 and in Reference 15. Table 6-1 MCPR limits are bounding for both GEl 1 and GNF2 fuel. The Kf multipliers are documented in Reference 2 and Reference 15. Table 6-1 limits are independent of APRM status changes since Reference 2 and Reference 15 analyzes the Rod Withdrawal Error (RWE) as unblocked. The appropriate Kf value may be determined by linear interpolation. Table 6-2 is applicable to GEl 1 and GNF2 fuel types per Reference 2 and Reference 15.

Table 6-1 provides two sets of MCPR limits. One set is for "Nominal" response function for the Turbine Bypass Valve (TBV) where the TBV fast opening to 80% of rated TBV flow has been demonstrated to be 1 second or less and has a TBV fast opening delay time of 200 msec or less (Reference 14). The other set, referred to as "Slow to Open", represents MCPR limits which have taken no credit for the fast opening function of the TBV during a Feedwater Controller Failure (FWCF) event. The application of the ("Nominal" versus "Slow to Open") MCPR limits is dependent on the results of TBV testing. Operation with one TBVOOS is independent of the TBV fast opening response time since the 1 TBVOOS MCPR limits in Table 6-1 take no credit for TBV response (References 2 and 15).

6.2. Power Dependent MCPR Limits The use of GNF2 fuel type requires the application of power dependent MCPR limits at off-rated conditions.

Power dependent limits are required because APRM Trip Setdown may not provide adequate protection for the MCPR Safety Limit. Use of these limits ensures that the MCPR Safety Limit is not violated as a result of any anticipated operational occurrence (AOO). Plant specific power dependent MCPR limits are presented in Table 6-3 and documented in Reference 2 and Reference 15. When core thermal power is greater than or equal to 40% of rated, the Kp multiplier from Table 6-3 is applied to the applicable rated condition MCPR limit shown in Tables 6-1. The appropriate MCPRp or Kp value may be determined by linear interpolation. Below 40% of rated power, the MCPR limits in Table 6-3 are applied directly. Table 6-3 is applicable to both GEl 1 and GNF2 fuel types per Reference 2 and Reference 15.

Table 6-3 provides two sets power dependent MCPR limits at off-rated conditions. One set is for "Nominal" response function for the Turbine Bypass Valve (TBV) where the TBV fast opening to 80% of rated TBV flow has been demonstrated to be 1 second or less and has a TBV fast opening delay time of 200 msec or less (Reference 14). The other set, referred to as "Slow to Open", represents power dependent MCPR limits which have taken no credit for the fast opening function of the TBV during a Feedwater Controller Failure (FWCF) event. The application of the ("Nominal" versus "Slow to Open") power dependent MCPR limits is dependent on the results of TBV testing. Operation with one TBVOOS is independent of the TBV fast opening response time since the 1 TBVOOS MCPR limits in Table 6-3 take no credit for TBV response (References 2 and 15).

6.3. Scram Time Core average scram insertion times are determined per Technical Specifications 3.2.B. Based on the results of the scram time surveillance testing and calculation of the core average insertion time, a MCPR limit is chosen from Table 6-1 (Reference 2 and Reference 15). If the core average scram insertion time does not meet the Option B criteria, but has met Option A criteria, then the appropriate MCPR value may be determined from a linear interpolation between the Option A and B limits with standard mathematical rounding to two decimal places.

The scram time adjustment to MCPR only applies to MCPR limits that are set by pressurization transients (see Note 3 to Table 6-1 for further clarification).

Table 6-1 "Slow to Open" TBV response function MCPR limits are applicable to the slow opening of the TBV as determined by TBV testing.

2 The referenced MCPR cycle exposure breakpoint (EOR-4016) MWD/ST is conservative to the value (EOR-3716) MWD/ST in Reference 2 to allow for changes to the end of rated cycle exposure due to cycle operation.

' The documented MCPR limit is based on the Rod Withdrawal Error (RWE) event, which is a non-pressurization event. The limiting pressurization event results in an Option B MCPR limit that is 0.01 less (BOC to (EOR-4016) MWD/ST) than the RWE event. Scram time adjustments are only required to be applied to MCPR limits that are set by pressurization transients.

4 For three recirculation loops in service, the MCPR operating limit is 0.02 greater than the four/five loop value per Reference 2.

' 1TBVOOS MCPR limits are independent of TBV response function because no credit is taken for the TBV response function.

7. Linear Heat Generation Rate The LHGR limits are discussed in Technical Specifications Section 3.10.B. The maximum LHGR shall not exceed the LHGR limits as specified in Appendix A. The exposure dependent U0 2 and Gd 20 3 Thermal-Mechanical LHGR limits are contained in Appendix A and apply to all modes of operation as described in Table 9-1. Power dependent LHGR multipliers are listed in Table 7-1 for PROOS operating conditions and are applicable to GEl I and GNF2 fuel types (Reference 2). The power adjusted LHGR for PROOS operating conditions is determined by multiplying the applicable Appendix A LHGR limit by the LHGR multiplier, LHGRFACp, given in Table 7-1. Flow dependent LHGR multipliers are listed in Table 7-2 for one TBVOOS operating condition and are applicable to GEl 1 and GNF2 fuel types (Reference 2 and Reference 15) for operation above 95% core thermal power. The flow adjusted LHGR for one TBVOOS operating condition is determined by multiplying the applicable Appendix A LHGR limit by the LHGR multiplier, LHGRFACf, given in Table 7-2. The appropriate LHGRFACp and LHGRFACf values may be determined by linear interpolation.

8. Stability Protection Settings The stability protection settings are discussed in Technical Specifications 2.3. Oyster Creek utilizes the BWROG Option II solution in the licensing stability calculations. Table 8-1 provides the analytical limit equations for APRM based stability protection settings and related Control Rod Block settings to support Option II implementation (References 2 and 6).

1. Introduction and Summary This report, which supplements the Supplemental Reload Licensing Report, contains thermal-mechanical linear heat generation rate (LHGR) limits for the GNF-A fuel designs to be loaded into Oyster Creek for Cycle 24. These LHGR limits are obtained from thermal-mechanical considerations only. Approved GNF-A calculation models documented in Reference 1 were used in performing this analysis.

LHGR limits as a function of exposure for each bundle of the core design are given in Appendix A. The LHGR values provided in Appendix A provide upper and lower exposure dependent LHGR boundaries which envelope the actual gadolinia dependent LHGR limits. The LHGRs reported have been rounded to two places past the decimal.

Appendix B contains a description of the fuel bundles. Table B-I contains a summary of bundle-specific information, and the figures provide the enrichment distribution and gadolinium distribution for the fuel bundles included in this appendix. These bundles have been approved for use under the fuel licensing acceptance criteria of Reference 1.
