3/4.3 INSTRUMENTATION

. BASES 3/4.3.1 and 3/4.3.2 REACTOR PROTECTIVE SYSTEM (RPS) AND _ ENGINEERED SAFEGUARDS SYSTEM (ESS) INSTRUMENTATION The OPERABILITY of the RFS and ESS instrumentation systems and permissive circuits ensure that 1) the associated ESS action and/or RPS trip will be initiated when the parameter monitored by each channel or combination thereof exceeds its -setpoint, 2) the specified coinci-dence logic is maintained, 3) sufficient redundancy is maintained, and

4) sufficient system functional capability is available for RPS and ESS purposes from diverse parameters.

The OPERABILITY of these systems is required to provide the overall reliability, redundance and diversity assumed available in the facility design for the protection and mitigation of accident and transient con-ditions. The integrated operation of each of these systems is consistent with the assumptions used in the accident analyses.

The surveillance requirements specified for these systems ensure that the overall system functional capability is maintained comparable to the original design standards. The periodic surveillance tests -

performed at the minimum frequencies are sufficient to demonstrate this capability.

3/4.3.3 MONITORING INSTRUMENTATION 3/ 4. 3. 3.1 RADIATION MONITORING INSTRUMENTATION

- The OPERABILITY of the radiation monitoring channels ensures that

1) the radiation levels are continually measured in the areas served by the individual channels and 2) the alarm or automatic action is in-itiated when the radiation level trip retpoint is exceeded.

The OPERABILITY of the neutron detectors is demonstrated prior to use by

~

irradiating each detector to be used and normalizing their outputs.

3 /4. 3. 3. 3 METEOROLOGICAL INSTRUMENTATION Th-OPERABILITY of the meteorological instrumentation ensures that sufficient meteorological data is available for estimating potential

! radiation doses to the public as a result of routine or accidental release of radioactive materials to the atmosphere. This capability is required to evaluate the need for initiating protective measures to protect the health l and safety of the public (and is consistent with the recommendations of I Regulatory Guide 1.23, "Onsite Meteorological Programs").

i 3 /4. 3. 3. 4 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 safety related equipment and is an integral element in the overall

~

facility fire protection program.

i In the event that a portion of the fire detection instrumentation-l 1s inoperable, the establishment of freqdent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is restored to OPERABILITY.

Su 3/4.4 MAIN COOLANT SYSTEM BASES 3 /4.'4.1 MAIN COOLANT LOOPS The plant is designed to operate with all main coolant loops in operation, and maintain DNBR above 1.30 during all normal operations and anticipated transients. With one main coolant loop not in operation.

THERMAL POWER is restricted to < 75 percent of RATED THERMAL POWER.

With four loops operating, a loss of flow or low SG water level in two locps will cause a reactor trip. A loss of flow or low SG water level 1

7 in one loop will cause a reactor trip with three loops operating.

Adequate main coolant loops are required to provide sufficient heat removal capability for removing core decay heat.

Single failure con-siderations require placing the Shutdown Cocling System into operation if the required main coolant loops are.not OPERABLE. A steam generator is capable of removing core decay heat by natural or forced circulation provided the conditions specified in 4.4.1.1.2 are ret.

The requirement to maintain the boron concentration of an isolated loop greater than or equal to the boron concentration of the operating loops ensures that no reactivity addition to the core could occur during startup of an isolated loop. Verification of the boron concentration in.

an' isolated loop prior to opening the stop valves provides a reassurance of the adequacy of the boron concentration in the isolated loop. Startup of an. isolated loop will inject cool water from the loop into the core.

The reactivity transient resulting from this cool water injection is minimized by delaying isolated loop startup until its temperature is within 30*F of the operating loops. Making the reactor subcritical prior to loop startup prevents any power spike which could result from this cool water induced reactivity transient.

The prohibition on starting a main ccolant purp witnout a bubble in the pressurizer or with a SG/MCS terperature difference of > 100*F requirement is necessary to prevent exceeding the isotherral Appendix G curve limits under the most restrictive MC flow initiation transient'if the PORV or SCS relief valves fail.

3/a.a.2 and 3/4.4.3 SAFETY VALVES The pressurizer code safety valves operate to prevent the Main Ccolant System from being pressurized above its Safety Limit of 2735 psig.

Each safety valve is designed to relieve 92,000 lbs per hour of saturated steam at the valve set point.

Th-relief capacity of a single safety valve is adequate to relieve any cverpressure ccndition which cculd occur during shutdcwn.

In the ev n: that no safety valves are C?E'lABLE, an ccerating Shutdctn Ccoling System connected to the Main

-oc,lant Syster prcvides overpressure relief capability and will prevent Main Coolant System overpressurizaticn during shutdcwn.

SAE Y VALVES (Continued)

During operation, all pressurizer code safety valves must be OPERABLE

o prevent the Main Coolant System from being pressurized above its safety 11:10 of 2735 psig. The combined relief capacity of all of these valves is greater than the maximum surge rate resulting from a complete loss of load assuming no reactor trip until the first Reactor Protective System trip setpoint is reached (i.e., no credit is taken for a direct reactor i trip on the loss of load) and also assuming no operation of the power operated relief valves or steam dump valves.

Demonstration of the safety valves' lift settings will occur only during shutdown and will be performed in accordance with the provisions of Section XI of the ASME Boiler and Pressure Code.

1 The MCS passive code safety valves, SV-204 and SV-205, are available l

0 to relieve expansion or mass addition at all HCS temperatures < 300 F.

Ea:h of the two valves has the capacity to relieve 101 gpm of 400 F water at a set pressure of 47.5 psig plus 10% accumulation. The low setpoint PORV,

?R-S3V-90, is available to relieve expansion or mass addition at MCS temperature _< 324 F.

The power operated relief valve (PORV) operates to relieve MCS

{ pres sure below the setting of the pressurizer code safety valves. This relief valve has a remotely operated block valve to provide a positive shatof f capability should the relief valve become inoperable. The electrical j pcwer for the block valve is capable of being supplied from an emergency

' p ver source to ensure the ability to seal this possible MCS leakage path.
