D. During power operation, the requirements of 15.3.2-B and C may be modified to allow the following components to be inoperable for a specified time. If the system is not restored to meet the requirements of 15.3.2-B or C within the time period specified, the ,

appropriate reactor (s), except as otherwise noted, shall be placed in the hot shutdown condition within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and borated to a shutdown margin equivalent of at least 1.0%

delta k/k at cold shutdown, no xenon conditions. If the requirements of 15.3.2 0 or C are not satisfied within an additional 7 days, the appropriate reactor (s) shall be placed in the cold shutdown condition within the next 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

1. One of the two operable charging pumps associated with an operating reactor may be removed from service provided a charging pump associated with that reactor is restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
2. One of the two boron injection flow paths specified in B.2 or C.2 may be out of service provided two boron injection flow paths are restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
3. One of the boric acid transfer pumps designated in B.3 or C.3 may be out of service provided a boric acid transfer pump is restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

ILisis The chemical and volume control system provides control of the reactor coolant system boron inventory. This is normally accomplished by using one or more charging pumns in series with one of the two boric acid transfer pumps. Above cold shutdown conditions, a minimum of two boron injection now paths are required per unit to insure functional capability in the event that an assumed single active failure renders one of the now paths inoperable. The boration volume available through any flow path is sufficient to provide the required shutdown margin at cold shutdown, xenon-free conditions from any expected operating condition. The madmum-volume requirement is associated with boration from just critical, hot zero or full powei, peak xenon with control rods at the insertion limit, to xenon free, cold shutdown with the highest worth control rod assembly fully withdrawn. This requires approximately 24rl00 2M&O_ gallons of M00 220appm barated water from the refueling water storage tank (RWST) or the concentrations and volumes of borated water specified in Table 15.3,2-1 from the boric acid storage tanks (BASTS).

expeiience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

Specifications 15.3.6.C. and D.

The shutdown conditions of the reactor are selected based on the type of activities that are being carried out. When the reactor head is not to be removed, the specified cold shutdown margin of 1% Ak/k precludes criticality under any occurrence. During refueling the reactor is suberitical by 5% Ak/k. Positive reactivity changes for the purpose of rod assembly testing will not result in criticality because no control bank worth exceeds 3%. Positive reactivity changes by baron dilution may be required or small concentration fluctuations may occur during preparation for, recovery from, or during refueling but maintaining the boron concentration greater than 4300 2100 ppm; precludes criticality under these circumstances. -4404)L0appm; is a nominal value that ensures 5% shutdown for typical reload cores. Should continuous dilution occur, the time intervals for this incident are discussed in Section 14.13f of the FSAll.
