NOTES FOR TABLE 3.2.A

1. Whenever the respective functions are required to be operable there shall be two operable or tr1pped trip systems for each function.

If the first column cannot be met for one of the trip systems, that trip system or logic for that function shall be tripped (or the ap-propriate action listed below shall be taken).

If the column cannot be met for all trip systems, the appropriate action listed below shall be taken.

A.

Initiate an orderly shutdown and have the reactor in Cold Shutdown in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

F.

The handling of spent fuel will be prohibited and all operat1ons over spent fuels and open reactor wells shall be prohibited.

G.

Isolate the reactor building and start the standby gas treatment system.

H.

Immediately perform a logic system functional test on the loaic in the other trip systems and daily thereafter not to exceed 7 days.

I.

DELETE J.

K.

Manually isolate the affected lines.

Refer to section 4.2.E for the requirements of an inoperable system.

L. If one SGTS train is inoperable take actions H or A and F. If two SGTS trains are inoperable take actions A and F.

2. When it is determined that a channel is failed in the unsafe cond1tion, the other channels that monitor the same variable shall be functionally tested immediately before the trip system or logic for that function is tripped.

The trip system or the logic for that function may remain untripped for short periods of time to allow functional testing of the other trip system or logic for that function.

3. There are four sensors per steam line of which two must be operable.

4. Only required in Run Node (Interlocked with Mode Switch).

5. Not required in Run Mode (bypassed by mode switch).

A channel may be placed in an inoperable status for up to four hours for required surveillance without placing the trip system in the tripped condition provided at least one OPERABLE channel in the same trip system is monitoring that parameter.

12.

A channel contains four sensors, all of which must be operable for the channel to be operable.

Power operations permitted for up to 30 days with 15 of the 16 temperature switches operable.

In the event that normal ventilation is unavailable in the main steam line tunnel, the high temperature channels may be bypassed for a period of not to exceed four hours.

During periods when normal ventilation is not available, such as during the performance of secondary containment leak rate tests, the control room indicators of the affected space temperatures shall be monitored for indications of small steam leaks.

In the event of rapid increases in temper-ature (indicative of steam line break), the operator shall prompt-ly close the main steam line isolation valves.

13'he nominal setpoints for alarm and reactor trip (1.5 and 3.0 times background, respectively) are established based on the normal back-ground at full power.

The allowable setpoints for alarm and reactor trip are 1.2 - 1.8 and 2.4 3,6 times background, respectively.

Instrument check is included in this table for convenience and to indicate that an Instrument Check will be performed on the instrument.

Instrument checks are not required when these instruments are not required to be operable or are tripped.

Local alarm lights representing upscale and downscale trips will be verified, but no rod block will be produced at this time.

The inop-erative trip will be initiated to produce a rod block (SRM and IRM inoperative also bypassed with the mode switch in RUN).

The functions that cannot be verified to produce a rod block directly will be ver-ified during the operating cycle.

The functional test vill consist of infecting a simulated electrical signal into the measurement channel.

Teated during logic system functional tests.

Refer to Table 4.1.B.

The logic system functional tests shall include a calibration once per operating cycle of time delay relays and timers necessary for proper functioning of the trip systems.

The functional test vill consist of verifying continuity across the inhibit vith a volt-ohmmeter.

Definitions).

An instrument check is not applicable to a particular setpoint, such as Upscale, but is a qua1itative check that the instrument is behaving and/or indicating in an acceptable manner for the particular plant condition.

Instrument check is included in this table for convenience and to indicate that an Instrument Check villbe performed on the instrunent.

Instrument checks are not required vhen these instruments arc not required to be operable or are tripped Calibraticn frequency shall be once/year.

DELETE portion of t.hc logic ia functionally tested during outage only The detector vill be inserted during each operating cycle and thc proper amount of travel into the core verified functional test villconsist of applying simulated inputs (scc note 3).

Local alarm lights representing upscale and dovnscale tripe <<ill be verified, but no rod block vill bc produced at this time.

The inoperative trip F11 be initiated to produce a rod block (SRH and IJN inoperative also bypassed vith the mode avitch in RUN) ~

The functions that cannot be verified to produce a rod block directly vill be verified during the operating cycle.
