, DEFINITIONS

' Axial Shape Index (ASI) i ASI shall be the power generated in the lower half of the core less the power generated in the upper half of the core, divided by the sum of the power generated in the lower and I upper halves of the core.

ASI = 3 Wer- upper , y lower + upper The Axial Shape Index (Y i) used for the trip and pretrip signals in the Reactor Protection System (RPS) is the above value (Yc) modified by an appropriate multiplier (A) and a constant (B) to determine the true core axial power distribution for that channel.

Yi = AYs + B Total Integrated Radial Peaking Factor- F[

The Total Integrated Radial Peaking Factor is the ratio of the peak pin pnwer to the ,

average pin power in an unrodded core, i

Total Planar Radial Peaking Factor - F,y' The Total Planar Radial Peaking Factor is the maximum ratio of the peak to average power density of the individual fuel rods in any of the unrodded horizontal planes.

CYCLE SPECIFIC LIMITS FOR UNIT 2, CYCLE 13 l l

3.1.1 Shutdown Margin (SDM)(SR 3.1.1.1)

Tavg > 200 *F- Afodes 3 and 4:

The shutdown margin shall be equal to or greater than the limit line of COLR Figure 3.1.1.

Tavg S 200 F- Afode 5:

The shutdown margin shall be 2 3.0% Ap.

3.1.3 Moderator Temperature Coefficient (MTC) (SR 3.1.3.2)

The Moderator Temperature Coefficient (MTC) shall be less negative than -3.0 x 10-4 Ap/ F at rated thermal power.

'3.1.4 Control Element Assembly (CEA) Alignment (Action 3.1.4.B.1)

The allowable time to realign a CEA may be provided by the full core power distribution monitoring system (Better Axial Shape Selection System - BASSS) or COLR Figure 3.1.4,

" Allowable Time to Realign CEA Versus Initial Total Integrated Radial Peaking Factor (F,T)." If COLR Figure 3.1.4 is used, the pre-misaligned F, value used to determine the allowable time to realign the CEA shall be the latest measurement taken within 5 days prior to the CEA misalignment, if no measurements have been taken within 5 days prior to the misalignment and the full core power distribution monitoring system is unavailable then the time to realign is zero(0) minutes.

3.1.6 Regulating Control Element Assembly (CEA) Insertion Limits (SR 3.1.6.1 and SR 3.1.6.2)

The regulating CEA groups insertion limits are shown on COLR Figure 3.1.6.

3.2.1 Linear Heat Rate (LHR)(SR 3.2.1.2 and SR 3.2.1.4)

The linear heat rate shall not exceed the limits shown on COLR Figure 3.2.1-1. l The axial shape index power dependent control limits are given in COLR Figure 3.2.1-2.

When using the excore detector monitorine system (SR 3.2.1.2):

The alarm setpoints are equal to the ASI limits, therefore when the alarms are adjusted, they provide indication to the operator when ASI is not with the limits.

The maximum allowable fraction of rated thermal power vs. F,[ is shown in COLR Figure 3.2.1-3.

The axial shape index alarm setpoints are shown on COLR Figure 3.2.1-2.

When using the incore detector monitoring system (SR 3.2.1.4):

The alarm setpoints are adjusted to protect the Linear Heat Rate limits shown on COLR Figure 3.2.1-1 and uncertainty factors are appropriately included in the setting of these alarms.

55% when BASSS is operable, or within the limits of COLR Figure 3.2.5 for CEA insertions specified by COLR Figure 3.1.6.

3.3.1 Reactor Protective System (RPS) Instrumentation - Operating (Reactor Trip Setpoints) (TS Table 3.3.1-1)

The Axial Power Distribution - High trip setpoint and allowable values are given in COLR Figure 3.3.1-1.

The Thermal Margin / Low Pressure (TMILP) trip setpoint is given in COLR Figures 3.3.1-2 and 3.3.1-3. The allowable values are to be not less than the larger of(l) 1875 psia or (2) the value calculated from COLR Figures 3.3.1-2 and 3.3.1-3.

3.9.1 Boron Concentration (SR 3.9.1.1)
