D C. COOK '- UNZT 2 B 3/4 7-3 Amendment No.77
IIAN Modes 2 and 3: With one or more steam generator stop valves inoperable, close the inoperable valve(s) within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> and verify the inoperable valves are closed at least once per 7 days. Otherwise, be in at least MODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, with the unit in at least MODE 3 within the first 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
The provisions of Specification 3.0.4 are not applicable.
tl B h With one steam generator stop valve inoperable in MODE 1, action must be taken to restore OPERABLE status within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. Some repairs to the valves can be made with the unit hot. The 8 hour completion time is reasonable, considering the low probability of an accident occurring during this time period that would require a closure of the steam generator stop valves. If the steam generator stop valve cannot be restored to OPERABLE status within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, the unit must be placed in a MODE in which the LCO does not apply. To achieve this status, the unit must be placed in MODE 2 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and the MODES 2 and 3 action statement entered. The completion times are reasonable, based on operating experience, to reach MODE 2 and to close the steam generator stop valves in an orderly manner and without challenging unit systems.
Since the steam generator stop valves are required to be OPERABLE in MODES 2 and 3, the inoperable valves may either be restored to OPERABLE status or closed. When closed, the valves are already in the position required by the assumptions in. the safety analysis. The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> completion time is consistent with the MODE 1 action statement requirement. For inoperable steam generator stop valves that cannot be restored to OPERABLE status within the specified completion time, but are closed, the inoperable valves must be verified on a periodic basis to be closed. This is necessary to ensure that the assumptions in the safety analysis remain valid. The 7 day completion time is reasonable, based on engineering judgement, in view of steam generator stop valve status indications available in the control room, and other administrative controls, to ensure that these valves are in the closed position.
If in MODES 2 or 3 the steam generator stop valves cannot be restored to OPERABLE status or are not closed within the associated completion time, the unit must be placed in a MODE in which the LCO does not apply. To achieve this status, the unit must be placed at least in MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in MODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The allowed completion times are reasonable, based on operating experience, to reach the required unit conditions from MODE 2 conditions in an orderly manner and without challenging unit systems.
