Sections 3.22. 3..4.1. and 3.7_6_ 42 Desaiplion:

DOCIID:COIBCfirdlm 1 Rmr.13 The Operatin_g Limit MCPR (OLMCPR) is determined from eilher Section 4.2.1 or 4.22,, whichever is greater at any given power and flow condition.

4.2.1 Power--Dependent MCPR For operation less than or equal to 33.3% core thennal power, the MCPR(P) as a function of core thennal power is delermined from Table 4-2 or Table 4-3 depending on p!ant conditions.

For operation at greater than 33.3% core thennal power. the OLMCPR as a function of core thermal power is determined by multiplying the applicable rated condition 01..MCPR limit shown in Table 4-1 by the applicable MCPR multiplier K{P) given in Table 4-2 or Table 4-3. 4.22 Flow-Dependent MCPR Tables 44 through 4-7 give the MCPR(F) as a function of flow based on the appficable plant concfltion.

The limits for dual loop operation are listed in Tables 44 and 4-6. The limits for single loop operation are listed in Tables 4-5 and 4-7. The MCPR{F) delennined from these tables is the flow dependent OLMCPR 4.2.3 Option A and Option B Option A and Option B refer to use of scram speeds for establishing MCPR operating limits. Option A scram speed is the BWR/6 Technical Specification scram speed. The Technical Specification scram speeds must be met to utilize the Option A MCPR limits. Cycle-specific reload analyses performed by GNF for Option A MCPR limits utilized a 20% core average

• insertion time of 0.516 seconds (Reference 6). To utilize the MCPR limits for the Option B scram speed, the cycle average scram insertion time for 20% insertion must satisfy equation 2 in Reference 5 Section 4. If the cycle average scram insertion time does not meet the Option B criteria, the appropriate MCPR value may be determined from a linear interpolation between the Option A and B limits as specified by equation 4 in Reference 5 Section 4. 4.2.4 Recirculation Flow Control Valve Settings The cycle was analyzed with a maximum core flow runout of 109%; therefore, the recirculation flow control valve must be set to maintain core flow less than 109% (92.105 Mlb/hr) for all runout events (References 3 and 12).

Description:

The operability requirements for the Main Turbine Bypass System are governed by Technical Specification 3.7.6. If the requirements of LCO 3.7.6 cannot be met, the appropriate reactorthennal power, minimum critical power ratio (MCPR), and linear heat generation rate (LHGR) limits must be used to comply with the assumptions in the design basis transient analysis.

Table 7-1 provides the reador thennal power limitations for an inoperable Main Turbine Bypass System as specified in Technical Specification LCO 3.7.6. The MCPR and LHGR limits for one TBVOOS are included in the Base Case, as identified in Table 9-1. The MCPR and LHGR limits for two or more TBVOOS are provided in Sections 4 and 5.

12) 4. For operation with Loss of 'FULL' Feedwater Heating {a change in temperature greater than 10 "F, but less than or equal to 50 "F FWTR), the MAPLHGR is determined using the multiplier in Table 3-3 and the LHGR value is determined from Tables 5-7, 5-8, and 5-9. 5. Concurrent operation with either or both of PROOS + PLUOOS is allowed. 6. Includes 2 SRVOOS and up to a 50°F feedwater temperature reduction

{FWTR includes feedwater heater OOS or final feedwater temperature reduction}

at any point in cycle operation in Dual Loop mode. {Reference 12} 7. End-of-cycle power coastdown operation down to 40% reactor power is supported by Methodology Reference

1. Coastdown operation beyond the EOR condition is conseivatively bounded by the reload licensing analyses at the EOR condition for a normal coastdown power profile. During coastdown, operation at a power level above that which can be achieved (at all-rods-out with all cycle extension features utilized, e.g., ICF, FFWTR) with steady-state equilibrium xenon concentrations is not supported.
