The core operating limits are developed using NRC approved methodology (References 1, 3, 4, 10, and 13),and are established such that all applicable thermal limits of the plant safety analysis aremet.The SLMCPR of 1.15 was used for two-loop operation for all fuel types in Cycle 27. TheSLMCPR for single loop operation is 1.15. These values are consistent with the valuesspecified in Reference 2.This report includes the Option III Generic Shape Function (GSF) definition for theBackup Stability Protection (BSP) region, which is used in providing backup thermalhydraulic stability protection when the Option III OPRM system is declaredINOPERABLE.

Figure 4, which shows the flow-dependent CPR limits, is now bounded by the ECCSMCPR value as specified in Reference

Technical Specification 3.2.2.NAD-MN-033, Monticello Cycle 27 CLTP COLR, Revision 0Page 5 of 46 5.3 Pressure Regulator Out of Service (PROOS) Operation Reference 18 GE SIL 614, Revision 1 describes the impact of operation without a backuppressure regulator (also called PROOS). This section provides power dependent MCPRlimits when a backup pressure regulator is not operational.

The existing power dependent MAPLHGR and LHGR limits described in Sections 8.1 and8.2 have been found to be valid (bounding) for operation without a backup pressureregulator (References 19 and 2).A Pressure Regulator Fails Down-Scale (PRFDS) event without backup pressureregulator was evaluated for Monticello (Reference 19). This event resulted in a morerestrictive Power Dependent MCPR limit than required for normal reduced poweroperation with both pressure regulators operational.

This event was re-evaluated forCycle 27 (Reference

2) and determined to be more restrictive than the results inReference
19. Figure 8 provides the required more restrictive power dependent MCPRARTS limits for powers below 85% and greater than or equal to 45%. For powers greaterthan or equal to 85% or below 45%, the power dependent MCPR and K(P) ARTS limitsprovided in Figure 3 are still valid. The ARTS limits are described in Reference
17. Thenew Pressure Regulator Out of Service limits are applicable for Cycle 27 (Reference 2).Figure 8 combines the unchanged limits from Figure 3 along with the more restrictive limits determined in Reference 2 for PROOS operation.

Figure 8 should only be used foroperation without a backup pressure regulator.

Figure 8 is valid for both Option A andOption B OLMCPR limits.An interim MFLCPR Limit is provided in Figure 9. This limit should only be used if theGardel thermal limit input has not been modified as described in Sections 5.3.1 or 5.3.2to account for pressure regulator out of service operation.

I.e., only Figure 8 or Figure 9should be used to provide the appropriate PROOS limit. These figures should not beutilized in combination.

5.3.1 OLMCPR for Two Recirculation Loop Operation, WITHOUT A BACKUPPRESSURE REGULATOR.

The Option A or B OLMCPR shall be determined for two recirculation loop operation as follows:The Option A OLMCPR is calculated as shown below for the Option B example withthe following exception:

No channel bow effects are included in thebounding MAPLHGR values in Tables I through 14 as there are no reused channels.

MAPLHGR limits for each individual fuel lattice for a given bundle design as a function ofaxial location and average planar exposure are determined based on the approvedmethodology referenced in Monticello Technical Specification 5.6.3.b and are loaded intothe process computer for use in core monitoring calculations.

When and if hand calculations are required:

8.1.1 Two-Recirculation Loop Operation (MAPLHGR)

At rated core thermal power and core flow conditions, the MAPLHGR limit foreach fuel bundle design as a function of average planar exposure shall notexceed the bounding limits provided in Tables 1 through 14.The MAPLHGR limit is adjusted for off-rated core thermal power and core flowconditions by determining the following:

MAPLHGR(P)

= MAPFAC(P)

= MAPFAC(F)

  • MAPLHGR limit from Tables 1 through 14.where MAPFAC(P) and MAPFAC(F) are determined from Figures 1 and 2,respectively, and where P is the core thermal power in percent of rated, and Fis the core flow in percent of rated.The Technical Specification (TS) MAPLHGR limit is determined as follows:MAPLHGR (TS) Limit = Minimum{MAPLHGR(P),

MAPLHGR(F)}

Note that all natural uranium lattices are excluded in Tables 1 through 14.Straight line interpolation between nearest data points is permitted only withineach individual Tables 1 through 14.8.1.2 Single Recirculation Loop Operation (MAPLHGR)

When in single recirculation loop operation, perform the following:

8.1.2.1 Perform the action specified in Section 8.1.1 above.8.1.2.2 Separately, apply the single loop operation multiplier to the limitingvalues of MAPLHGR from Tables 1 through 14 as follows:for GE14C: multiplier is 0.90.8.1.2.3 Select the more limiting (i.e. smaller) value from Sections 8.1.2.1 or8.1.2.2.

Technical Specification 3.2.1.NAD-MN-033, Monticello Cycle 27 CLTP COLR, Revision 0Page 8 of 46 8.2 Linear Heat Generation Rate (LHGR)The uranium dioxide (U02) and gadolinia LHGR limits as a function of fuel rod peak pelletexposure for each bundle type in Cycle 27 is provided in Tables 15 through 28. Thegadolinia LHGR limits in Tables 15 through 28 are bounding gadolinia LHGR limits for allthe gadolinia concentrations occurring in each of the bundle types used in Cycle 27. TheLHGR limits are fuel rod nodal limits, and are to be applied at every node of the fuel rodincluding the natural uranium lattices.

The individual LHGR limits for the uranium dioxide and gadolinia fuel rods in each fuelbundle type used in Cycle 27, as a function of axial location and pellet exposure aredetermined based on the approved methodology referenced in Monticello Technical Specification 5.6.3.b and are loaded into the process computer for use in core monitoring calculations.

The LHGR limits are presented in this report for use when and if hand calculations areperformed to demonstrate compliance with Technical Specification 3.2.3.When and if hand calculations are performed:

8.2.1 Two-Recirculation Loop Operation (LHGR)At rated core thermal power and core flow conditions, the LHGR limit for eachfuel bundle design as a function of peak pellet exposure and fuel pin type shallnot exceed the bounding limits provided in Tables 15 through 28.The LHGR limit is adjusted for off-rated core thermal power and core flowconditions by determining the following:

LHGR(P) = MAPFAC(P)

  • LHGR limit from Tables 15 through 28.LHGR(F) = MAPFAC(F)
  • LHGR limit from Tables 15 through 28.where the multipliers MAPFAC(P) and MAPFAC(F) are determined from Figures1 and 2, respectively, and where P is the core thermal power in percent of rated,and F is the core flow in percent of rated.The Technical Specification (TS) LHGR limit is determined as follows:LHGR TS Limit = Minimum{LHGR(P),

LHGR(F)}Note that the LHGR limits are fuel rod nodal limits, and are to be applied at everynode of the fuel rod, including the natural uranium lattices.

Straight lineinterpolation between nearest data points is permitted only within each individual Tables 15 through 28.8.2.2 Single Recirculation Loop Operation (LHGR)When in single recirculation loop operation, perform the following:

8.2.2.1 Perform the same action specified in Section 8.2.1 above. There areno separate single loop operation specific multipliers applicable toLHGR, i.e. the multipliers from Section 8.2.1 also apply to singlerecirculation loop operation.

NAD-MN-033, Monticello Cycle 27 CLTP COLR, Revision 0Page 30 of 46 9.0 Core Stability Requirements Stability Option III SolutionMonticello has implemented the BWR Owners Group Long Term Stability Solution OptionIII using the Oscillation Power Range Monitor (OPRM) as described in References 4 and10. The plant specific Hot Channel Oscillation Magnitude (HCOM) (Reference

11) andother cycle specific stability parameters are used in the Cycle 27 Option III Stability Evaluation, which is documented in Reference
2. A Backup Stability Protection (BSP)evaluation is also documented in References 2 and 13, and is used in the event that theOption III OPRM system is declared INOPERABLE.

The following Option III OPRM stability setpoint determination and the implementation ofthe associated BSP Regions shown in Figures 5 and 6 provide the stability licensing bases for Monticello Cycle 27.Option III OPRM Setpoints A reload Option III evaluation has been performed in accordance with the licensing methodology described in Reference

4. The stability based Operating Limit MinimumCritical Power Ratio (OLMCPR) is determined for two conditions as a function of OPRMamplitude setpoint.

The two conditions evaluated are: (1) a postulated oscillation at 45%rated core flow quasi steady-state operation (SS), and (2) a postulated oscillation following a two recirculation pump trip (2PT) from the limiting rated power operating statepoint.The OPRM-setpoint-dependent OLMCPR(SS) and OLMCPR(2PT) values are calculated for Cycle 27 in accordance with the BWROG regional mode DIVOM guidelines described in Reference

12. The Cycle 27 Option Ill evaluation provides adequate protection againstviolation of the Safety Limit MCPR (SLMCPR) for the two postulated reactor instability events as long as the plant OLMCPR is equal to or greater than OLMCPR(SS) andOLMCPR(2PT) for the selected OPRM setpoint in Table 30.The relationship between the OPRM Successive Confirmation Count Setpoint and theOPRM Amplitude Setpoint is provided in Reference 4 and Table 29. For intermediate OPRM Amplitude Setpoints, the corresponding OPRM Successive Confirmation CountSetpoints have been obtained by using linear interpolation.

The OPRM setpoints for Two Loop Operation (TLO) are conservative relative to SingleLoop Operation (SLO) and are, therefore, bounding.

The BSP regions are an integral part of the Tech Spec requiredalternative method to detect and suppress thermal hydraulic instability oscillations in thatthey identify areas of the power/flow map where there is an increased probability that thereactor core could experience a thermal hydraulic instability.

Regions are identified that are either excluded from planned entry and continued operation (Scram Region),

or where planned entry is not permitted unless specificoperating restrictions are met and specific actions are required to be taken to immediately leave the region following inadvertent or forced entry (Controlled Entry Region).

Theboundaries of these regions are established on a cycle specific basis based upon coredecay ratio calculations performed using NRC approved methodology (Reference 3).The BSP regions are only applicable when the Upscale Trip function of the OPRMis INOPERABLE.

The BSP region boundaries were calculated for Monticello Cycle27 for nominal feedwater temperature conditions.

The endpoints of the regions aredefined in Table 31. The region boundaries shown in Figures 5 and 6 are definedusing the Generic Shape Function (GSF), which is described in References 13 and25.Table 31Cycle 27 BSP Region Intercepts for Normal Feedwater Temperature RegionBoundary Power Core Flow Core DR HighestIntercepts N%(%) N Channel DRAl 63.9 40.0 <0.80 <0.56B1 48.1 33.8 <0.80 <0.56A2 72.8 50.0 <0.80 <0.56B2 32.3 31.2 <0.80 <0.56Actions For Entry Into Scram RegionImmediate manual scram upon determination that the region has been entered.

Ifentry is unavoidable, early scram initiation is appropriate.

Actions For Entry Into Controlled Entry RegionIf entry is inadvertent or forced, immediately exit from region. The region can beexited by control rod insertion or core flow increase.

Increasing the core flow byrestarting an idle recirculation pump is not an acceptable method of exiting theregion.Deliberate entry into the Controlled Entry Region requires compliance with at leastone of the stability controls outlined below:1. Maintain core average boiling boundary (BB) > 4.0 feet.2. Maintain core decay ratio (DR) < 0.6 as calculated by an on-line stability monitor.3. Continuous dedicated monitoring of real time control room neutronmonitoring instrumentation with manual scram required upon indication of areactor instability induced power oscillation.

Caution is required whenever operating near the Controlled Entry Regionboundary (i.e., within approximately 10% of core power or core flow), and it isNAD-MN-033, Monticello Cycle 27 CLTP COLR, Revision 0Page 33 of 46 recommended that the amount of time spent operating near this region beminimized.

OLMCPR can be found inSection 5 of this report. If the Option B scram time dependence option is preferred, then theprocedure listed in Section 10.1 may be used.10.1 Technical Specification Scram Time Dependence Technical Specification 3.1.4 and Table 3.1.4-1 provide the scram insertion time versusposition requirements for continued operations.

Technical Specification Surveillance Requirements SR 3.1.4.1 -SR 3.1.4.4 provide the surveillance requirements for theCRDs. Data from testing of the CRDs, or from an unplanned scram, is summarized inSurveillance Test 0081. Reference 8 describes the procedure below.Using this cycle specific information, values of Tave can be calculated in accordance withthe equation below for the notch 36 position.

The Equation (1) used to calculate the average of all the scram data generated to date inthe cycle is:XNirii=1rave = n1Ni(1)where: n = the number of surveillance tests performed to date in the cycle;nn=1=total number of active control rods measured to date in the cycle; andsum of the scram times to the 36th notch position of all active rodsmeasured to date in the cycle to comply with the Technical Specification surveillance requirements SR 3.1.4.1, SR 3.1.4.2, SR 3.1.4.3, SR 3.1.4.4.NAD-MN-033, Monticello Cycle 27 CLTP COLR, Revision 0Page 34 of 46 The average scram time, .ave is tested against the analysis mean using the following equation:

rave <-- TB(2)where:VBa =P+(3)The parameters jt and a are the mean and standard deviation of the distribution of theaverage scram insertion time to notch 36 position in the ODYN Option B analysis (Table32), and N1 = number of active control rods tested at BOC.Table 32GEMINI Methods, CRD Notch Position for TB Determination Notch Position I a I36 0.830 1 0.019If the cycle average scram time satisfies the Equation 2 criteria, continued plant operation under the ODYN Option B operating limit minimum critical power ratio (OLMCPR) forpressurization events is permitted.

If not, the OLMCPR for pressurization events must bere-established based on linear interpolation between the Option B and Option A OLMCPRs.Note that Option B has an OLMCPR applicable to two recirculation loop operation, andan OLMCPR applicable to single recirculation loop operation.

The Option B OLMCPRvalue for single recirculation loop operation is the same as the Option B OLMCPR valuefor two recirculation loop operation.

The Turbine Trip with Bypass transient will be used as the Minimum OLMCPRtransient for Option B Analysis.

3. For Options A and B, the OLMCPR value for single recirculation loop operation isequal to the OLMCPR value for two recirculation loop operation.

Sample Calculation:

Assume two recirculation loop operation.

If cave is 0.820 seconds (scram time test) and tB (as calculated with equation
