NOTES
FOR TABLE 3.2.8

- 1. Whenever any CSCS-subsystem'is required by Section'3.5 to be operable, there shall be two (Note.5) operable trip systems, i f the first column cannot be met for one of the trip systems, that: system shall be repaired or the reactor shall be placed in the Cold Shutdown Condition within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after this trip system is .made or found ~to- be inoperable.

2. Close isolatiori valves in RCIC subsystem.
3. Close isolation valves in HPCI subsystem.
4. Instrument set point corresponds to 77.26 inches of active fuel.
5. RCIC has only one trip system for those sensors.
