Instrumentation to measure the drywell to suppression chamber differential pressure and the torus water level shall be operable at any time the differential pressure is required to be maintained by Specification
?.5.A.9.a.
Operation may continue for up to thirty days with one instrument out of service.
If both differential pressure or both water level instruments are not operable, or if one instrument is out of service for more than thirty days, and such indication cannot be restored in the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, the reactor shall be in the shutdown condition within the following 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />.

- 1. Secondary containment integrity shall be maintained at all times unless all of the following conditions are met:
a)
The reactor is subcritical and Specification 3.2.A is met.
b)
The reactor is in the cold shutdown condition.
c)
The reactor vessel head or the drywell head are in place.
d)
No work is being performed on the reactor or its connected systems in the reactor building which could result in inadvertent releases of radioactive material.
e)
No operations are being performed in, above, or around the spent fuel storage pool that could cause release of radioactive materials.
