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 Unit I Cycle 9 WATTS BAR Page 2 of 10 Revision 0 COLR for Watts Bar Unit 1, Cycle 9 2.1 MODERATOR TEMPERATURE COEFFICIENT
-MTC (LCO 3.1.4)2.1.1 The MTC limits are: The BOL/ARO/HZP
-MTC shall be less positive than or equal to 0 Ak/k/0 F (upper limit). With the measured BOL/ARO/HZP
-MTC more positive than -1.00 x 10-5 Ak/k/°F (as-measured MTC limit), establish control rod withdrawal limits to ensure the MTC remains less positive than or equal to 0 Ak/k/0 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 Ak/k/0 F (lower limit).2.1.2 The 300 ppm surveillance limit is: The measured 300 ppm /ARO/RTP-MTC should be less negative than or equal to-3.75 x 10-4 Ak/k/°F.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than or equal to-4.28 x 10-4 Ak/k/0 F.2.2 SHUTDOWN BANK INSERTION LIMITS (LCO 3.1.6)2.2.1 The shutdown banks shall be withdrawn to a position greater than or equal to 225 steps withdrawn.
2.3 CONTROL
BANK INSERTION LIMITS (LCO 3.1.7)2.3.1 The control banks are fully withdrawn or shall be limited in physical insertion as shown in Figure 1.2.3.2 Each control bank shall be considered fully withdrawn from the core at greater than or equal to 225 steps.Unit 1 WATTS BAR Cycle 9 Revision 0 Page 3 of 10 COLR for Watts Bar Unit 1, Cycle 9 2.3.3 The control banks shall be operated in sequence by withdrawal of Bank A, Bank B, Bank C, and Bank D.
