== Description:== 1.2.1 GE Fuel The MAPLHGR limit is determined from Table 1,1, and is either MAPLHGRp or MAPLHGR,, whichever is lower at any given power, flow condition. No thermal limit monitoring is required below 25% power, However, if official monitoring is desired, the lattice type MAPLHGR limits as determined froin Table 1.2 may be used, and multiplied by the appropriate MAPFACp values in Figures 1.2-1 or 1.2-2 or the MAPFAC, values in Figure 1.2-3 whichever is more limiting.

== Description:== 2.2.1 Manual Flow Control MCPR Limits The Governing MCPR Operating Limit while in Manual Flow Control is either determined from 2.2.1.1 or 2.2.1.2, whichever is greater at any given power, flow condition. 2.2.1.1 Power-Dependent MCPR (MCPRp)" (Reference 4) 2.2.1.1.1 GE Fuel Table 2-1 gives the MCPRp limit as a function of core thermal power for Tech Spec Scram Speeds. Table 2-2 gives the MCPRp limit as a function of core thermal power for Nominal Scram Speeds *. 2.2.1.1.2 Siemens Fuel Table 2-3 gives the MCPRp limit as a function of core thermal power for Tech Spec Scram Speeds. Table 2-4 gives the MCPRp limit as a function of core thermal power for Nominal Scram Speeds *. 2.2.1.2 Flow-Dependent MCPR (MCPRp) (Reference 4) Figure 2-1 gives the MCPRp limit as a function of flow. f

  • To utilize the MCPR limits for Nominal Scram Speeds, the core average scram speed insertion times must be equal to or less than the following values at the given notch positions:

GE98-P8CWB320-9GZ3-100M-150-CECO 3.2.2 Siemens Fuel The LHGR Limit is the product of the Steady-State LHGR Limit and the minimum of either the power dependent LHGR Factor *, LHGRFACp or the flow dependent LHGR Factor, LHGRFAC,. The Steady-State LHGR limits are given below (Reference 4). LHGRFAC, is determined from Table 3-1 for Technical Specification Scram Speeds and Table 3-2 for Nominal Scram Speeds as defined in Section 2.2. LHGRFAC, is determined from Figure 3-1. Siemens Fuel Steady-State LHGR Limits for the following fuel types: 1. SPCA9-3818-13GZ7-80M 2. SPCA9-384B-11GZ6-80M Planar Average Exposure (GWd/MTU) LHGR (kW/ft) 0.0 14.4 15.0 14.4 61.1 8.32

  • For thermallimit monitoring at greater than 100%P, the 100% power LHGRFACp limits should be applied.

Feedwater Heaters OOS may be an actual OOS condition, or an intentionally entered mode of operation to extend the cycle energy. 3 If operating with Feedwater Heaters Out-of-Service, operation in ELLLA is supported by current transient analyses, but administratively prohibited due to core stability concerns. 4 EOC Recirculation Pump Trip OOS/Feedwater Heaters OOS is allowed during non-coastdown operation using the TCV Slow Closure /EOC necirculation Pump Trip OOS/Feedwater Heaters OOS operating limits. 5 Only when operating in coastdown, otherwise this combination is not allowed. 6 Operation is only allowed when less than 10.5 million Ibm /hr steam flow and when average position of 3 open TCVs is less than 50% open, with FCL <-108%, and the MCFL setpoint 2120%. TCV Stuck Closed may be in combination with any EOOS except TBVOOS or TCV Slow Closure.

Administrative ToChniCal Requirements - App ndix B L2C8 Core Operating Limits Report 6. Traversing in-Core Probe System (3/4.2.1,3/4.2.3,3/4 2.4) 6.1 Tech Soec

Reference:

Tech Spec Sections 3/4.2.1,3/4.2.3,3/4.2.4 for APLHGR, MCPR, and LHGR require the TIP system for recalibration of the LPRM detectors and monitoring thermallimits.

6.2 Descriction

When the traversing in-core probe (TIP) system (for the required measurement locations)is used for recalibration of the LPRM detectors and monitoring thermal limits, the TIP system shall be operable with the following: 1. movable detectors, drives and readout equipment to map the core in the required measurement locations, and 2. indexing equipment to allow all required detectors to be calibrated in a common location. With one or more TlP measurement locations inoperable, the TIF data for an inoperable measurement location may be replaced by data obtained from a 3-dimensional BWR core monitoring software system adjusted using the previously calculated uncertainties, provided the following conditions are met: 1. All TIP traces have previously been obtained at least once during a calibration in the current operating cycle which was performed when the reactor core was operating in an octant symmetric control rod pattern above 50% power, (Reference 22) and 2. The total core Tlf r rtainty for the present cycle has been demonstrated to be consistent with th2 asumptions used in the determination of the MCPR Safety Limit (demonstrated by showing chi squared to be less than 36.19, Reference 21), and / 3. The toto, i,Jmber of simulated channels (measurement locations) does not exceed 42% (18 channels). Otherwise, with the TIP system inoperable, suspend use of the system for the above applit,able monitoring or calibration functions.

6.3 Bases

The operability of the TIP system with the above specified minimum complement of equipment ensures that the measurements obtained from use of this equipment accurately represent the spatial neutron flux distribution of the reactor core. The normalizatic,i of the required detectors is performed internal to the core monitoring software system. Startup test criteria for symmetric measured TIP differences is that the calculated Chi-squared value shall ' be less than the critical value at the 1% level of significance; that critical value being 36.19. Compliance is determined based on the values and methodology provided in Reference 21. Substitute TIP data, if needed, is 3-dimensional BWR core monitoring software calculated data which is adjusted based on axial and radial factors calculated from previous TIP sets. Since uncertainty could be introduced by the simulation and adjustment process, a maximum of 18 channels may be simulated to ensure that the uncertainties assumed in the substitution process methodology remain valid.
