lost and is consistent with General Design Criteria 19 of 10 CFR 50.

The OPERABILITY of the remote shut'down instrumentation in Panel L411 ensures that sufficient capability is available to permit shutdown and mainte-nance of (OLD SHUTDOWN of the facility in the event of a fire in the cable spreading room, control room or remote shutdown panel, LO42.

3/4.3.3.6 ACCIDENT MONITORING INSTRUMENTATION The OPERABILITY of the accident monitoring instrumentation ensures that sufficient information is available on selected plant parameters to monitor and assess these variables following an accident.

This capability is consistent with the recommendations of Regulatory Guide 1.97, " Instrumentation for Light-Water-Cooled Nuclear Plants to Assess Plant C'onditions During and Following an Accident," December 1975 and NUREG 0578, "TMI-2 Lessons Learned Task Force Status Report and Short-Term Recommendations".

The containment high range area monitors (RU-148 & RU-149) and the main steamline radiation monitors (RU-139 A&B and RU-140 A&B) are in Table 3.3-6.

The high range effluent monitors and samplers (RU-142, RU-144 and RU-146) are in Table 3.3-13.

The containment hydrogen monitors are in Specification 3/4.6.5.1.

The Post Accident Sampling System (RCS coolant) is in Table 3.3-6.

The Subcooled Margin Monitor (SMM), the Heated Junction Thermocouple (HJTC),

and the Core Exit Thermocouple (CET) comprise the Inadequate Core Cooling (ICC) instrumentation required by Item II.F.2 NUREG-0737, the Post TMI-2 Action Plan.

The function of the ICC instrumentation is to enhance the ability of the plant operator to diagnose the approach to existence of, and recovery from ICC..Addi-tionally, they aid in tracking reactor coolant inventory. These instruments are included in the Technical Specifications at the request of MRC Generic Letter 83-37.

These are not required by the accident analysis, nor to bring the plant to Cold Shutdown.

In the event more than four sensors in a Reactor Vessel Level channel are inoperable, repairs may only be possible during the next refueling outage. This is because the sensors are accessible only after the missile shield and reactor vessel head are removed.

It is not feasible to repair a channel except during a refueling outage when the missile shield and reactor vessel head are removed to refuel the core.

If only one channel is inoperable, it should be restored to OPERABLE status in a refueling outage as soon as reasonably possible.

If both channels are inoperable, both channels shall be restored to OPERABLE status in the nearest refueling outage.

In the event that both HJTC channels are in-operable, exis, ting plant instruments and operator training will be used as an

. alternate method of monitoring the reactor vessel inventory.

Revised INSTRUMENTATION BASES 3/4.3.3.7 FIRE DETECTION INSTRUMENTATION I

OPERABILITY of the fire detection instrumentation ensures that adequate warning capability is available for the prompt detection of fires.

This capability is required in order to detect and locate fires in their early stages.

Prompt detection of fires will reduce the potential for damage to safe shutdown and/or safety-related equipment and is an integral element in the overall facility fire protection program.

In the event that less than 50% of the fire detection instrumentation is inoperable in any fire area / zone, the establishment of frequent fire patrols in the affected areas is required to provide detection capability until the i

inoperable instrumentation is restored to OPERABLE.

Since the fire detectors are non-seismic, a plant visual inspection for fires is required within two hours following an earthquake (> 0.05g).

Since safe shutdown systems are protected by seismic Category I barriers, any fire after an earthquake should be detected by this inspection before safe shutdown systems would be affected.

Additionally, to verify the continued OPERABILITY of fire detection systems after an earthquake, an engineering evaluation of the fire detection instrumentation in the required zones is required to be per-formed within 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months following an earthquake.

3/4.3.3.8 RADI0 ACTIVE LIQUID EFFLUENT INSTRUMENTATION The radioactive liquid effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents.

The alarm /

trip setpoints for these instruments shall be calculated in accordance with the procedures in the ODCM to ensure that the alarm / trip will occur prior to exceeding the limits of 10 CFR Part 20.

The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50.

3/4.3.3.9 RADI0 ACTIVE GASE0US EFFLUENT INSTRUMENTATION The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases of gaseous effluents. The alarm / trip setpoints for these instruments shall be calculated in accordance with the procedures in the ODCM to ensure that the alarm / trip will occur prior to exceeding the limits of 10 CFR Part 20.

This instrumentation also includes provisions for monitoring and controlling the concentrations of potentially explosive gas mixtures in the waste gas holdup system.

The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50.

l 3/4.3.3.10 LOOSE-PART DETECTION INSTRUMENTATION The OPERABILITY of the loose part detection instrumentation ensures that I

sufficient capability is available to detect loose metallic parts in the pri-l mary system and avoid or mitigate damage to primary system components.

INSTRUMENTATION j

f BASES room.

This capability is required in the event control roont habitability is lost and is consistent with General Design Criteria 19 of 10 CFR 50.

The OPERABILITY of the remote shutdown instrumentation in Panel L411 ensures that sufficient capability is available to permit shutdown and mainte-nance of C,0LD SHUTDOWN of the facility in the event of a fire in the cable spreading room, control room or remote shutdown panel, LO42.

4 3/4.3.3.6 ACCIDENT MONITORING INSTRUMENTATION The OPERABILITY of the accident monitoring *instrtTmentation ensures that sufficient information is available on selected plant parameters to monitor and assess these variables following an accident. This capability is consistent with the recommendations of Regulatory Guide 1.97, " Instrumentation for Light-Water-Cooled Nuclear Plants to Assess Plant Obnditions During and Following an Accident," December 1975 and NUREG 0578, "THI-2 Lessons Learned Task Force Status Report and Short-Term Recommendations".

The containment high range area monitors (RU-148 & RU-149) and the main steamline radiation monitors (RU-139 A&B and RU-140 A&B) are in Table 3.3-6.

The high range effluent monitors and samplers (RU-142, RU-144 and RU-146) are in Table 3.3-13.

The containment hydrogen monitors are in Specification 3/4.6.5.1.

The Post Accident Sampling System (RCS coolant) is in Table 3.3-6.)

The Subcooled Margin Monitor (SMM), the Heated Junction Thermocouple (HJTC),

and the Core Exit Thermocouple (CET) comprise the Inadequate Core Cooling (ICC) instrumentation required by Item II.F.2 NUREG-0737, the Post THI-2 Action Plan.

The function of the ICC instrumentation is to enhance the ability of the plant operator to diagnose the approach to existence of, and recovery from ICC.,Addi-tionally, they aid in tracking reactor coolant inventory.

These instruments are included in the Technical Specifications at the request of NRC Generic Letter 83-37.

These are not required by the accident analysis, nor to bring the plant to Cold Shutdown.

In the event more than four sensors in a Reactor Vessel Level channel are inuperable, repairs may only be possible during the next refueling outage. This is because the sensors are accessible only after the missile shield and reactor vessel, head are removed.

It is not feasible to repair a channel ex. cept during a refueling outage when the missile shield and reactor vessel head are removed to refuel the core.

If only one channel is inoperable, it should be restored to OPERABLE status in a refueling outage as soon as reasonably possible.

If both channels are inoperable, both channels shall be restored to OPERABLE status in the nearest refueling outage.

In the event that both HJTC channels are in-operable, existing plant instruments and operator training will be used as an alternate method of monitoring the reactor vessel inventory.

3/4.3.3.7 FIRE DETECTION INSTRUMENTATION OPERABILITY of the fire detection instrumentation ensures that adequate warning capability is available for the prompt detection of fires.

This capability is required in order to detect and locate fires in their early stages.

Prompt detection of fires will reduce the potential for damage to safe shutdown and/or safety-related equipment and is an integral element in the overall f acility fire protection program.

In the event that less than 50% of the fire detection instrumentation is inoperable in any fire area / zone, the establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is restored to OPERABLE.

Since the fire detectors are non-seismic, a plant visual inspection for fires is required within two hours following an earthquake (>0.05g).

Since safe shutdown systems are protected by seismic Category I barriers, any fire after an earthquake should be detected by this inspection before safe shutdown systems would be affected.

Additionally, to verify the continued OPERABILITY of fire detection systems after an earthquake, an engineering evaluation of the fire detection instrumentation in the required zones is required to be per-formed within 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months following an earthquake.

3/4.3.3.8 RADI0 ACTIVE LIQUID EFFLUENT INSTRUMENTATION The radioactive liquid effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents.

The alarm /

trip setpoints for these instruments shall be calculated in accordance with the procedures in the ODCM to ensure that the alarm / trip will occur prior to exceeding the limits of 10 CFR Part 20.

The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50.

3/4.3.3.9 RADI0 ACTIVE GASE0US EFFLUENT INSTRUMENTATION The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases of gaseous effluents.

The alarm / trip setpoints for these instruments shall be calculated in accordance with the procedures in the ODCH to ensure that the alarm / trip will occur prior to exceeding the limits of 10 CFR Part 20.

This instrumentation also includes provisions for monitoring and controlling the concentrations of potentially explosive gas mixtures in the waste gas holdup system.

The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50.
