1: When block condition exists, maintain normal operation.

2: Channels should be operable at all modes below the bypass condition with the reactor trip system breakers in the closed position and control rod drive system capable of rod withdrawal.

3: Channels shall be operable at all modes below the bypass condition except during refueling defined to be when fuel is in the reactor vessel with the vessel head closure bolts less than fully tensioned or with the head removed.

4: One reactor trip breaker may be bypassed for surveillance testing provided the other reactor trip breaker is operable.

5: Channels shall be operable at all modes above refueling when the control rod drive system is capable of rod withdrawal unless both reactor trip br'eakers are open.

Should the next Channel Functional Test require the bypass of an inoperable channel to avoid the generation of an actuation signal, operation may proceed until this Channel Functional Test.

With the number of operable channels less than the Minimum Operable Channels

required, operation may continue provided the containment purge and exhaust valves are maintained closed.

14.

Should one reactor trip breaker or channel of trip logic be inoperable the plant must not be in the operating mode following a six hour time period, and the breaker must be open.

If one of the diverse reactor trip breaker trip features (undervoltage or shunt trip attachment) on one breaker is inoperable, restore it to operable status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or declare breaker inoperable.

and the reactor trip breaker must be open, following an additional six hour time period.

The breaker shall not be bypassed while one of the diverse trip features is inoperable except for the time required for performing maintenance to restore the breaker to operable status.

The test shall also verify the operability of the bypass breaker.

Using test switches in the reactor protection rack manually trip the reactor trip bypass'reaker using the shunt trip coil.

Automatically trip the under-voltage trip attachment.

NOTE 1: Logic trains will be tested on alternate months corresponding to the reactor trip breaker testing.

Monthly logic testing will verify the operability of all sets of reactor trip logic actuating contacts on that train (See Note 3).

Refueling shutdown testing will verify the operability of all sets of reactor trip actuating contacts on both trains.

In testing, operation of one set of contacts will result in a reactor trip breaker trip; the operation of all other sets of contacts will be verified by the use of indication circuitry.

NOTE 2: Testing shall be performed monthly, unless the reactor trip breakers are open, or shall be performed prior to startup if testing has not been performed within the last 30 days.

NOTE 3= The source range trip logic may be excluded from monthly testing provided it is tested within 30 days prior to startup.
