2.0 OPERATING LIMITS
The cycle-specific parameter limits for the specifications listed in section 1.0 are presented in the following subsections. These limits have been developed using the NRC approved methodologies specified in the Technical Specifications Section 5.9.5.
The following abbreviations are used in this section:
BOL -- Beginning of Cycle Life ARO -- All Rods Out HZP -- Hot Zero Thermal Power EOL -- End of Cycle Life RTP -- Rated Thermal Power ROS -- RAOC Operating Space RA -- Required Action

2.1.1 The MTC limits are:
The ARO/HZP - MTC shall be less positive than or equal to 0 k/k/ °F (upper limit).
With the BOL/ARO/HZP - MTC more positive than -2.095 x 10-5 k/k/°F (BOL MTC limit), establish control rod withdrawal limits to ensure the MTC remains less positive than or equal to 0 k/k/ °F (upper limit) for all times in core life.
The EOL/ARO/RTP - MTC shall be less negative than or equal to
-4.5 x 10-4 k/k/°F (lower limit).
2.1.2 The 300 ppm surveillance limit is:
The 300 ppm /ARO/RTP-MTC should be less negative than or equal to
-3.75 x 10-4 k/k/°F.
Unit 1 Cycle 19 WATTS BAR Revision 0 2.1.3 The 60 ppm surveillance limit is:
The measured 60 ppm /ARO/RTP-MTC should be less negative than or equal to
-4.28 x 10-4 k/k/°F.
2.2 SHUTDOWN MARGIN - SDM (LCO 3.1.5, 3.1.6, 3.1.7)
2.2.1 Fo r TS 3.1.5, SDM shall be 1.6% k/k in MODE 1 and MODE 2.
2.2.2 For T S 3.1.6, SDM shall be 1.6% k/k in MODE 1 and MODE 2.
2.2.3 For TS 3.1.7, SDM shall be 1.6% k/k in MODE 1 and MODE 2 with keff 1.0.
2.3 SHUT DOWN BANK INSERTION LIMITS (LCO 3.1.6)
2.3.1 The shutdown ba nks shall be withdrawn to a position greater than or equal to 224 steps withdrawn.
2.4 CONTROL BANK INSERTION LIMITS (LCO 3.1.7)
2.4.1 The control banks are fully withdrawn or shall be limited in physica l insertion as shown in Figure 1.
2.4.2 Each control bank shall be considered fully withdrawn from the core at greater than or equal to 224 steps.
2.4.3 The control banks shall be operated in sequence by withdrawal of Bank A, Bank B, Bank C, and Bank D. The control banks shall be sequenced in reverse order upon insertion.
2.4.4 Each control bank not fully withdrawn from the core shall be operated with the following overlap as a function of park position.

Where P = Thermal Power / Rated Thermal Power
2.5.1 CFQ = 2.50
2.5.2 K(Z) is provided in Figure 2.
2.5.3 () = 1.03 () 1 +
100 where 1.03 is the fuel manufacturing tolerance,
() is the measured value of () and is the measurement uncertainty ( 5).
2.5.4 () equations are:
() 1.03 [()] () ( ) > 0.5 1 + 100
() 1.03 [()] () ( ) 0.5 0.5 1 + 100
Where () is the measured planar radial peaking factor.
() evaluations are not applicable for axial core regions, measured in percent of core height:
- a. Lower core region, from 0 to 10% inclusive,
- b. Upper core region, from 90 to 100% inclusive,
- c. Grid plane regions, +2% inclusive, and
- d. Core plane regions, within 2% of the bank demand positions of the control banks.
2.5.5 [()] values are provided in Tables A.1 and A.2 for ROS 1 and ROS 2, respectively.
2.5.6 () factors adjust the surveillance to the reference conditions assumed in generating the [ ()]factors. () may be assumed to be equal to 1.0 or may be determined for specific surveillance conditions using the approved methods listed in TS 5.9.5.
2.5.7 The penalty factors account for the potential decrease in transient FQ margin between surveillances. The factors for ROS 1 and ROS 2 are provided in Tables A.3 and A.4 respectively.
2.5.8 Table A.5 provides the required limits on THERMAL POWER and the required AFD reductions for each ROS in the event that additional margin is required.
