1.0 Core Operating Limits Report (COLR)

This Core Operating Limits Report for Monticello Nuclear Generating Plant (MNGP)

Cycle 27 at the Current Licensed Thermal Power (CLTP) of 1775 MWt is prepared in accordance with the requirements of Technical Specification 5.6.3. 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 are met.

The SLMCPR of 1.15 was used for two-loop operation for all fuel types in Cycle 27. The SLMCPR for single loop operation is 1.15. These values are consistent with the values specified in Reference 2.

This report includes the Option III Generic Shape Function (GSF) definition for the Backup Stability Protection (BSP) region, which is used in providing backup thermal hydraulic stability protection when the Option III OPRM system is declared INOPERABLE.

Figure 4, which shows the flow-dependent CPR limits, is now bounded by the ECCS MCPR value as specified in Reference 2.

,D 3.0 Rod Block Monitor Operability Requirements The ARTS Rod Withdrawal Error (RWE) analysis (Reference 2) validated that the following MCPR values provide the required margin for full withdrawal of any control rod during Monticello Cycle 27:

For Power < 90%: MCPR > 1.83 For Power >_90%: MCPR 1.50 When the core power is less than 90% of rated and the MCPR is less than 1.83, then a limiting control rod pattern exists and the Rod Block Monitor is required to be operable. If the core power is greater than or equal to 90% and the MCPR is less than 1.50, then a limiting control rod pattern exists and the Rod Block Monitor is required to be operable.

5.0 Minimum Critical Power Ratio (MCPR) 5.1 Option A The Operating Limit Minimum Critical Power Ratio (OLMCPR) for Option A does not account for scram speeds that are faster than those required by Technical Specifications.

5.1.1 Option A OLMCPR for Two Recirculation Loop Operation The Option A OLMCPR shall be determined for two recirculation loop operation as follows:

If core thermal power (P) is >_45% of rated core thermal power, then the Option A OLMCPR for all fuel types is the greater of {1.75

• K(P) from Figure 3} or {MCPR(F) from Figure 4}, where 1.75 is the Option A OLMCPR at rated (100%) core thermal power reported in Table 33.

i.e. if P >_45% rated core thermal power, then Option A OLMCPR limit

= Maximum of 1.75 * {K(P) from Figure 3} or {MCPR(F) from Figure 4}.

NAD-MN-033, Monticello Cycle 27 CLTP COLR, Revision 0 Page 4 of 46

If core thermal power (P) is < 45% of rated core thermal power, the Option A OLMCPR for all fuel types is obtained from Figure 3.

Technical Specification Section 3.2.2.

5.1.2 Option A OLMCPR for Single Recirculation Loop Operation The Option A OLMCPR as defined above for two recirculation loop operation in Section 5.1.1 is the same OLMCPR to be used for single recirculation loop operation.

Reference:

Technical Specification Section 3.2.2.

5.2 Option B Option B does take into account the measured scram speeds that are faster than the Technical Specification requirements, thus reducing the potential consequences of a limiting transient. Calculation of the Option B OLMCPR value as a function of measured scram speeds is described in Section 10.

5.2.1 Option B OLMCPR for Two Recirculation Loop Operation The Option B OLMCPR shall be determined for two recirculation loop operation as follows:

The rated (100%) core thermal power Option B OLMCPR (OLMCPRoptioB )is 1.66, and is reported in Table 33. This OLMCPRO'B00 of 1.66 is modified as described in Section 10 to be a function of the measured scram speeds to yield OLMCPR optionB.

5.3 Pressure Regulator Out of Service (PROOS) Operation Reference 18 GE SIL 614, Revision 1 describes the impact of operation without a backup pressure regulator (also called PROOS). This section provides power dependent MCPR limits when a backup pressure regulator is not operational.

The existing power dependent MAPLHGR and LHGR limits described in Sections 8.1 and 8.2 have been found to be valid (bounding) for operation without a backup pressure regulator (References 19 and 2).

A Pressure Regulator Fails Down-Scale (PRFDS) event without backup pressure regulator was evaluated for Monticello (Reference 19). This event resulted in a more restrictive Power Dependent MCPR limit than required for normal reduced power operation with both pressure regulators operational. This event was re-evaluated for Cycle 27 (Reference 2) and determined to be more restrictive than the results in Reference 19. Figure 8 provides the required more restrictive power dependent MCPR ARTS limits for powers below 85% and greater than or equal to 45%. For powers greater than or equal to 85% or below 45%, the power dependent MCPR and K(P) ARTS limits provided in Figure 3 are still valid. The ARTS limits are described in Reference 17. The new 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 for operation without a backup pressure regulator. Figure 8 is valid for both Option A and Option B OLMCPR limits.

An interim MFLCPR Limit is provided in Figure 9. This limit should only be used if the Gardel thermal limit input has not been modified as described in Sections 5.3.1 or 5.3.2 to account for pressure regulator out of service operation. I.e., only Figure 8 or Figure 9 should be used to provide the appropriate PROOS limit. These figures should not be utilized in combination.

5.3.1 OLMCPR for Two Recirculation Loop Operation, WITHOUT A BACKUP PRESSURE 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 with the following exception:

New The OLMCPRopti0,nB is replaced with the Option A OLMCPR of 1.75.

The Option B OLMCPR is calculated as follows:

The rated (100%) core thermal power Option B OLMCPR (OLMCPROptionB ) is 1.66, and is reported in Table 33. This OLMCPRoptionB of 1.66 is modified as described in New Section 10 to be a function of the measured scram speeds to yield OLMCPROption.

Then, if core thermal power (P) is _>85% of rated core thermal power, the Option B OLMCPR for all fuel types is the -greaterof:

OLMCPRptNeB * {K(P) from Figure 8) or {MCPR(F) from Figure 4},

i.e. if P >_85% rated core thermal power, then Option B OLMCPR limit Maw{

If core thermal power (P) is < 85% of rated core thermal power, the OLMCPR for all fuel types is obtained from Figure 8.

5.3.2 OLMCPR for Single Recirculation Loop Operation, WITHOUT A BACKUP PRESSURE REGULATOR The Option A or B OLMCPR as defined previously for two recirculation loop operation in Section 5.3.1 is the same OLMCPR to be used for single recirculation loop operation:

8.0 Fuel Rod Heat Generation Rate 8.1 Maximum Average Planar Linear Heat Generation Rate (MAPLHGR) as a Function of Exposure The MAPLHGR limits in Tables 1 through 14 are conservative values bounding all fuel lattice types (all natural uranium lattices are excluded) in a given fuel bundle design, and are intended only for use in hand calculations as described below to establish MAPLHGR limits for Technical Specification 3.2.1. No channel bow effects are included in the bounding MAPLHGR values in Tables 1 through 14 as there are no reused channels.

MAPLHGR limits for each individual fuel lattice for a given bundle design as a function of axial location and average planar exposure are determined 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.

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 for each fuel bundle design as a function of average planar exposure shall not exceed the bounding limits provided in Tables 1 through 14.

The MAPLHGR limit is adjusted for off-rated core thermal power and core flow conditions by determining the following:

MAPLHGR(P) = MAPFAC(P)

• MAPLHGR limit from Tables 1 through 14.

MAPLHGR(F) = 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 F is 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 within each 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 limiting values 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 or 8.1.2.2.

Technical Specification 3.2.1.

NAD-MN-033, Monticello Cycle 27 CLTP COLR, Revision 0 Page 8 of 46

8.2 Linear Heat Generation Rate (LHGR)

The uranium dioxide (U0 2) and gadolinia LHGR limits as a function of fuel rod peak pellet exposure for each bundle type in Cycle 27 is provided in Tables 15 through 28. The gadolinia LHGR limits in Tables 15 through 28 are bounding gadolinia LHGR limits for all the gadolinia concentrations occurring in each of the bundle types used in Cycle 27. The LHGR limits are fuel rod nodal limits, and are to be applied at every node of the fuel rod including the natural uranium lattices.

The individual LHGR limits for the uranium dioxide and gadolinia fuel rods in each fuel bundle type used in Cycle 27, as a function of axial location and pellet exposure are determined 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 are performed 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 each fuel bundle design as a function of peak pellet exposure and fuel pin type shall not exceed the bounding limits provided in Tables 15 through 28.

The LHGR limit is adjusted for off-rated core thermal power and core flow conditions 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 Figures 1 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 every node of the fuel rod, including the natural uranium lattices. Straight line interpolation 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 are no separate single loop operation specific multipliers applicable to LHGR, i.e. the multipliers from Section 8.2.1 also apply to single recirculation loop operation.

9.0 Core Stability Requirements Stability Option III Solution Monticello has implemented the BWR Owners Group Long Term Stability Solution Option III using the Oscillation Power Range Monitor (OPRM) as described in References 4 and

10. The plant specific Hot Channel Oscillation Magnitude (HCOM) (Reference 11) and other 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 the Option III OPRM system is declared INOPERABLE.

The following Option III OPRM stability setpoint determination and the implementation of the 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 Minimum Critical Power Ratio (OLMCPR) is determined for two conditions as a function of OPRM amplitude 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 state point.

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 III evaluation provides adequate protection against violation 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) and OLMCPR(2PT) for the selected OPRM setpoint in Table 30.

The relationship between the OPRM Successive Confirmation Count Setpoint and the OPRM Amplitude Setpoint is provided in Reference 4 and Table 29. For intermediate OPRM Amplitude Setpoints, the corresponding OPRM Successive Confirmation Count Setpoints have been obtained by using linear interpolation.

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

Backup Stability Protection Regions The Backup Stability Protection (BSP) regions are shown in Figure 5, and are given in greater detail in Figure 6. The BSP regions are an integral part of the Tech Spec required alternative method to detect and suppress thermal hydraulic instability oscillations in that they identify areas of the power/flow map where there is an increased probability that the reactor 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 specific operating restrictions are met and specific actions are required to be taken to immediately leave the region following inadvertent or forced entry (Controlled Entry Region). The boundaries of these regions are established on a cycle specific basis based upon core decay ratio calculations performed using NRC approved methodology (Reference 3).

The BSP regions are only applicable when the Upscale Trip function of the OPRM is INOPERABLE. The BSP region boundaries were calculated for Monticello Cycle 27 for nominal feedwater temperature conditions. The endpoints of the regions are defined in Table 31. The region boundaries shown in Figures 5 and 6 are defined using the Generic Shape Function (GSF), which is described in References 13 and 25.

If entry is unavoidable, early scram initiation is appropriate.

Actions For Entry Into Controlled Entry Region If entry is inadvertent or forced, immediately exit from region. The region can be exited by control rod insertion or core flow increase. Increasing the core flow by restarting an idle recirculation pump is not an acceptable method of exiting the region.

Deliberate entry into the Controlled Entry Region requires compliance with at least one 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 neutron monitoring instrumentation with manual scram required upon indication of a reactor instability induced power oscillation.

Caution is required whenever operating near the Controlled Entry Region boundary (i.e., within approximately 10% of core power or core flow), and it is NAD-MN-033, Monticello Cycle 27 CLTP COLR, Revision 0 Page 33 of 46

recommended that the amount of time spent operating near this region be minimized.

Technical Specification 3.3.1.1 10.0 Scram Time Dependence The Technical Specification Option A (no scram times dependence) OLMCPR can be found in Section 5 of this report. If the Option B scram time dependence option is preferred, then the procedure 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 versus position requirements for continued operations. Technical Specification Surveillance Requirements SR 3.1.4.1 - SR 3.1.4.4 provide the surveillance requirements for the CRDs. Data from testing of the CRDs, or from an unplanned scram, is summarized in Surveillance Test 0081. Reference 8 describes the procedure below.

Using this cycle specific information, values of -lave can be calculated in accordance with the equation below for the notch 36 position.

The Equation (1) used to calculate the average of all the scram data generated to date in the cycle is:

The parameters p and c are the mean and standard deviation of the distribution of the average scram insertion time to notch 36 position in the ODYN Option B analysis (Table 32), and N 1 = number of active control rods tested at BOC.

If not, the OLMCPR for pressurization events must be re-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, and an OLMCPR applicable to single recirculation loop operation. The Option B OLMCPR value for single recirculation loop operation is the same as the Option B OLMCPR value for two recirculation loop operation.

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

2. All the OLMCPR values reported in Table 33 are for two recirculation loop operation.

3. For Options A and B, the OLMCPR value for single recirculation loop operation is equal 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 3) is 0.850 seconds then the criteria from Equation 2 is met and the Option B OLMCPR of 1.66 can be used.

If 'Cave is 0.970 seconds and Tc[ is 0.850 seconds, then Equation 2 is not met and a new Option B OLMCPR must be calculated using Equation 4 above.
