1.0 Introduction and Summary This report provides the core operating limits for Average Planar Linear Heat Generation Rate (APLHGR), Minimum Critical Power Ratio (MCPR), Linear Heat Generation Rate (LHGR), Oscillation Power Range Monitor (OPRM)

Instrumentation and Rod Block Monitor Instrumentation for Columbia Generating Station Cycle 23 as required by Technical Specification 5.6.3. As required by Technical Specification 5.6.3, these limits were determined using NRG-approved methodology and are established so that all applicable limits of the plant safety analysis are met. The specific topical report revisions and supplements which describe the methodology utilized in this cycle specific analysis are shown in Table 1.1.

The reload licensing analyses for this cycle provide operating limits for Average Power Range Monitor I Rod Block Monitor and Technical Specifications Improvement Program (ARTS) and Maximum Extended Load Line Limit Analysis (MELLLA) operation which extends the power and flow operating regime for Columbia Generating Station up to the MELLLA boundary for Two Loop Operation (TLO). The core operating limits are applicable up to 100% of rated thermal power along and below the MELLLA boundary.

The minimum flow for operation at rated power is 80.7% of rated flow; the maximum is 106%. Single Loop Operation (SLO) is restricted to the Extended Load Line Limit Analysis (ELLLA) boundary. The core operating limits for both TLO and SLO are applicable for normal feedwater temperature, feedwater heaters out of service, final feedwater temperature reduction and coastdown. The Pressure Regulator Out of Service (PROOS) MCPR and LHGR limits are applicable if two (2) of the three (3) Digital Electro-hydraulic (DEH) pressure controllers are not functional.

3.0 Minimum Critical Power Ratio (MCPR) Operating Limits for Technical Specification 3.2.2 The MCPR operating limits for use in Technical Specification 3.2.2 are determined by the larger of the flow dependent (MCPRf) and power dependent (MCPRp) limits from Table 3.1 through Table 3.7. See Technical Specification 3.2.2 and the applicable Bases for further application details.

The MCPR safety limit for Cycle 23 is 1.10 for two loop operation (TLO) and 1.13 for single loop operation (SLO). The power and flow dependent MCPR limits for SLO require a 0.03 adder to the TLO MCPR limits due to the difference in the MCPR safety limit.

Notes for Table 3.1 Note 1: For Single Loop Operation (SLO), the SLMCPR increases by 0.03. This 0.03 increase must also be applied to the Two Loop Operation (TLO) MCPR Operating Limit to obtain the SLO Operating Limit. See Notes 5 and 6 for application details.

(Reference 7 .2 Section 11 )

Note 2: The cycle exposure range designation is defined in Table 3.1-1 for use in Table 3.1. End of Rated (EOR) is defined as the cycle exposure corresponding to all rods out, 100% power, 100% flow and normal feedwater temperature.

(Reference 7 .2 Section 7)

Note 3: The NRC has concluded that a statistical approach (Option B) may be used for pressurization events analyzed with TRACG (Reference 7.4, Section 7.5.2.6). In order to take credit for conservatism in the scram speed performance, it must be demonstrated that there is insufficient reason to reject the plant-specific scram speed as being within the distribution assumed in the statistical analysis.

The procedure described below determines the full power MCPR limit based on the scram times of SR 3.2.2.2. If the scram speed distribution is not within the assumed distribution, the MCPR limit for pressurization events must be re-established based on an interpolation between the applicable limits for Option A (scram times of LCO 3.1.4, "Control Rod Scram Times") and Option B (realistic scram times) analyses.

The surveillance information for the fuel cycle is the number of active control rods measured for each surveillance test (the first test is at the BOC and is denoted N1 ;

the ;th test denoted Ni) and the average scram time to Notch 39 for the active rods measured in test i denoted Tj.

The equation used to calculate the overall average of all the scram data generated to date in the cycle is:

11 LN;'f; 7: =-i=_l_ _

ave 11 (1)

LNi i=l where:

n = number of surveillance tests performed to date in the cycle; total number of active rods measured to date in the cycle; and Columbia Generating Station Page 7 COLR-01, Revision 23.2

sum of the scram time to Notch 39 of all active rods measured to date in the cycle to comply i=I with the Technical Specification surveillance requirements.

The average scram time, -c Ol\'., , is tested against the analysis mean using the following equation:

(2) where:

TB =µ+1.65 (3)

µ = 0.672 seconds (mean scram time to Notch 39 used in the Option B analysis) a = 0.016 seconds (standard deviation ofµ)

N1 = total number of active rods measured at BOC to comply with the Technical Specification surveillance requirements.

If the cycle average scram time satisfies the Equation 2 criterion, continued plant operation under the Option B MCPR limits for pressurization events is permitted. If not, the MCPR limits for pressurization events must be re-established, based on a linear interpolation between the Option Band Option A MCPR limits.

The equation to establish the new operating limit is given below:

OLMCPRNew =(OLMCPROptionB + t"ave -TB (SSAF)J (4)

TA -TB where:

!'ave and Te = defined in Equations 1 and 3, respectively 0.866 seconds (the Technical Specification limit on core average scram time to Notch 39)

SSAF= OLMCPRoptionA - OLMCPRoptiona (the difference between the MCPR calculated using Option A and that using Option B for pressurization events from Table 3 .1 )

OLMCPRoption A= the limiting pressurization event Option A MCPR limit OLMCPRoption B = the limiting pressurization event Option B MCPR limit Columbia Generating Station Page 8 COLR-01, Revision 23.2

If continued plant operation under the Option 8 MCPR limits for pressurization events is permitted, the Full Power Limit is the maximum of OLMCPRoption a and, if applicable, the Full Power Limit for Non-Pressurization Events. Otherwise, the Full Power Limit is the maximum of OLMCPRNew and, if applicable, the Full Power Limit for Non-Pressurization Events. (Reference 7 .2 Section 11)

Note 4: The Full Power Limit for Non-Pressurization Events is only applicable to SLO. The Full Power Limit for Non-Pressurization Events is specified when greater than the Option 8 Full Power Limit for Pressurization Events. See Note 3 for application guidance. (Reference 7.2 Section 11)

Note 5: Flow dependent MCPR limits (MCPRf) are applicable to TLO and require the SLO 0.03 adder when operating in SLO.

Note 6: 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 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. A step change in the power dependent MCPR limits occurs at 30% of rated power because direct scrams on turbine throttle valve closure and turbine governor valve fast closure are automatically bypassed below 30% of rated power and not applicable per Technical Specification 3.3.1.1.

The power dependent MCPR limits in Tables 3.2 through 3.6 are provided as Kp multipliers above the direct scram bypass power level (Pbypass) and as absolute MCPRp limits below Pbypass. MCPRp limits above Pbypass are determined through the following equation: MCPRp = Kp x (Full Power Limit). Power dependent MCPR limits are applicable to TLO and require the SLO 0.03 adder when operating in SLO. (Reference 7.2 Appendix D)

Note 7: A step change in the power dependent MCPR limits occurs at 85% of rated power because the APRM Neutron Flux - High scram is limiting at and above 85% and the Reactor Vessel Steam Dome Pressure - High scram is limiting below 85%.

Note 8: MCPR operating limits for Application Groups 1, 2 and 5 remain applicable for one bypass valve out of service. For two or more bypass valves out of service, Application Groups 3 and 4 are applicable.
