TABLE 3.2.6 NOTES Note 1 - From and af ter the date that one of these parameters is not indicated in the control room, continued reactor operation is permissible during the next seven days. If reduced to one indication of a parameter operation is permissible for 30 days.

00 CD Note 2 - Control rod position and neutron monitor instruments are considered to be redundant to each O other.

f$ Note 3 - From and after the date that this parameter is reduced to one indication in the control room.

00 cs continued reactor operation is permissible during the next thirty days. If both channels are inoperable and indication cannot be restored in six hours, an orderly shutdown shall be initiated and the in the reactor 18 following shall be in a hot shutdown condition in six hours and a cold shutdown condition hours.

1. Initially once per month; thereaf ter, a longer interval as determined by test results on this type of instrumentation. *.*1 *- .. -

2. During each refueling outage, simulated autom.itic actuation which opens all pilot valves shall be performed such that cach trip system logic can be verified independent of its redundant counterpart.

~

. 3. Trip system loci c calibration shall include only time delay relays and timers necessary for proper l , functioning of the trip system.

. .

I li's 4. This inctrumentation is excepted from functional test definition. The' functional test will consist a

of injecting a simulated electrical signal int:o the measurement channel.

5. Check control rod position indication while performing the surveillance requirement of section 3.3.

6. Functional. tests, calibrations an'd instrument checks are not required when these instruments are not to be operable or tripped. Functional tests shall be performed before cach startup with s required 4

frequency not to exceed once per week. Calibration shall be performed prior to or during each otartup or ,

controlled shutdowns wit h a required f requency not to exceed once per week. Instrument checks shall be performed at 1 cast once per day during those periods' when instruments are required to be operable. .

I 7. This instrumentatior. is excepted from the functional test definitions and shall be calibrated using ,

1 simulated cicetrical signals once every three contho.

8. Functional tests and calibrations are not required when systems are not required to be operable.

.9. The thermocouples associated with Safety / Relief Valves and Safety Valve Position, that may be used for backup position indication, shall be verified to be operable every operating tycle.

5. The plant IIcalth physicist shall meet or exceed the qualifications of Regulatory Guide 1.8, i

Revision 1 (September 1975).

6. .The Shif t Technical Advisor shall have a bachelor's degree or equivalcat in a scientific or engineering discipline with specific training in plant design, and response and analysis of the plant for transients and accidents.

E. A Fire trigade of at least 5 members shall be maintained onsite at all times. # This excludes 2 r: embers of the minimum shif t crew necessary for safe shutdown of the plant and any personnel required for other essential functions during a fire emergency.
