: 1. The Penalty Factor, which is applied to FQw(z) for compliance with Surveillance Requirement 3.2.1.2, is the maximum factor by which FQw(z) is expected to increase per 31 Effective Full Power Days (EFPD) starting from the burnup at which the FQw(Z) was determined. This Penalty Factor is applicable for both sets ofW(Z) Surveillance Factors provided in Tables A.1 and A.3.

2.1   MODERATOR TEMPERATURE COEFFICIENT - MTC (LCO 3.1.4) 2.1.1 The MTC limits are:
The ARO/HZP - MTC shall be less positive than or equal to OAk/k/&deg;F (upper limit).
With the measured BOL/ARO/HZP - MTC more positive than -2.12 x 10-5 Ak/k/&deg;F (as-measured MTC limit), establish control rod withdrawal limits to ensure the MTC remains less positive than or equal to OAk/k/&deg;F (upper limit) for all times in core life.
The EOL/ARO/RTP - MTC shall be less negative than or equal to
                -4.50 x 104 Ak/k/&deg;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/&deg;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/&deg;F.
2.2   SHUTDOWN MARGIN - SDM (LCO 3.1.5, 3.1.6, 3.1.7) 2.2.1 For TS 3.1.5, SOM shall be~ 1.6% ~k/k in MODE 1 and MODE 2.

2.2.3 For TS 3.1.7, SOM shall be~ 1.6% ~
in MODE 1 and MODE 2 with ketr~ 1.0.
2.3   SHUTDOWN BANK INSERTION LIMITS (LCO 3.1.6) 2.3.1 The shutdown banks shall be withdrawn to a position greater than or equal to 225 steps withdrawn.
2.4   CONTROL BANK INSERTION LIMITS (LCO 3.1.7) 2.4.1 The control banks are fully withdrawn or shall be limited in physical insertion as shown in Figure 1.
2.4.2 Each control bank shall be considered fully withdrawn from the core at greater than or equal to 225 steps.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.

The data in Tables A.1 and A.3 should be used independently; cross interpolation or extrapolation between W(Z) sets is prohibited.
Table A.1 values should be used when D-AO is in the range of2:-3% and :5 +3%.
Table A.3 values should be used when D-AO is in the range of 2: -6% and :5 0%.
These tables provide sufficient information to determine W (Z) versus core height for all cycle burnups.
2.5.4 Part power W(Z) values are only required to be used when the part power surveillance is performed using the fixed incore detector system.

: 1. The Penalty Factor, which is applied to Fow(z) for compliance with Surveillance Requirement 3.2.1.2, is the maximum factor by which Fow(Z) is expected to increase per 31 Effective Full Power Days (EFPD) starting from the burnup at which the FQw(z) was determined. This Penalty Factor is applicable for both sets ofW(Z) Surveillance Factors provided in Tables A.1 and A.3.
