2. l' SAFETY LIMITS BASES 2.1.1 REACTOR CORE The restrictions of this safety limit prevent overheating.of the fuel and possible cladding perforation which would result in the release of. fission products to the reactor coolant.
Overheating of'the fuel cladding is prevented by restricting fuel operation to within the I
nucleate boiling regime where the heat transfer coefficient is large and the cladding surface temperature is slightly above the coolant I
saturation temperature.
Operation above the upper boundary of the nucleate boiling regime could. result in excessive cladding temperatures because of the onset of departure from nucleate boiling (DNB) and the resultant sharp reduction in heat transfer coefficient.
DNB is not a directly-measurable parameter during operation and therefore THERMAL POWER and Reactor Coolant Temperature and Pressure have been related to DNB.
through the W-3 R-Grid correlation.
The W-3 R-Grid DNB correlation l has been developed to predict the DNB flux and the location of DNB for axially uniform and non-uniform heat flux distributions.
The local DNB heat flux
- ratio, DNBR, defined as the ratio of the heat flux that would cause DNB at a particular core location to the local heat flux, is indicative of the margin to DNB.
The minimum value of the DNBR during steady state operation, normal operational transients, and anticipated transients is limited to 1.30.
This value corresponds to a 95 percent probability at a 95 l
percent confidence level that DNB will not occur and is chosen as an appropriate margin to DNB for all operating conditions.
f The curves of Figures 2.1-1, 2.1-2 and 2.1-3 show the loci of points of THERMAL POWER, Reactor Coolant System pressure and, average temperature for which the minimum DNBR is no less than 1.30, or the average enthalpy at the vessel exit is equal to the enthalpy of l
saturated liquid.

3/4.0 APPLICABILITY BASES The specifications of this section provide the general requirements applicable to each of the Limiting Condition for Operation and Surveillance Requirements within Section 3/4.
3.0.1 This specification defines the applicability of each speci-fication in terms of defined OPERATIONAL MODES or other specified conditions and is provided to delineate specifically when each specification is applicable.
3.0.2 This specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.
3.0.3 This specification delineates the ACTION to be taken for circumstances not directly provided for in the ACTION statements and would violate the intent of the specification.
For whose occurrence
- example, Specification 3.5.1 calls for each Reactor Coolant System accumulator to be OPERABLE and provides explicit ACTION requirements if one accumulator is inoperable.
Under the terms of Specification 3.0.3, if more than one accumulator is inoperable, the unit is required to be in at least HOT STANDBY within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and in an least HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
As a further example, Specification 3.6.2.1 requires two Containment Spray Systems, to be OPERABLE and provides explicit ACTION requirements if one spray system is inoperable:
Under the terms of Specification 3.0.3, if both of the required Containment Spray Systems are inoperable, the unit is required to be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, in at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in at least COLD SHUTDOWN in the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
It is assumed that the unit is brought to the required MODE within the required times by promptly initiating and carrying out the appropriate ACTION statement.
3.0.4 This specification provides that entry into an OPERABLE MODE, or other specified applicability condition must be made with (a) the full complement of required systems, equipment or components OPERABLE and (b) all other parameters as specified in the Limiting Conditions for Operation being met without regard for allowable deviations and out of service provisions contained in the ACTION statements.
l The intent of this provision is to ensure that facility operation is initiated with either required equipment or systems inoperable or not other specified limits being exceeded.
this provision have been provided for a limited number Exceptions to of specifications when startup with inoperable equipment would not affect plant safety.
These exceptions are stated in the ACTION statements of the appropriate specifications.

be capable of performing their design functions and have an emergency power source OPERABLE).
In other words, both emergency power sources must be OPERABLE and all redundant
- systems, subsystems, trains, components and devices in both divisions must also be OPERABLE.
If these conditions are not satisfied, action is required in accordance with this specification.
In MODES 5
or 6 Specification 3.0.5 is not applicable, and thus the individual ACTION statements for each applicable Limiting Condition for Operation in these MODES must be adhered to.
4.0.1 This specification provides that surveillance activities to ensure the Limiting Conditions for Operation are met and l
necessary will be performed during the OPERATIONAL MODES or other conditions for which the Limiting Conditions for Operation are applicable.
Provisions for additional surveillance activities to be performed without regard to the applicable OPERATIONAL MODES or other provided in the individual Surveillance Requirements.
conditions are Surveillance Requirements for Special Test Exceptions need only be performed when the Special Test Exception is being utilized as an exception to an individual specification.
4.0.2 The provisions of this specification provide allowable tolerances for performing surveillance activities beyond those specified in the nominal surveillance interval.
These tolerances are necessary to provide operational flexibility because of scheduling and performance considerations.
The tolerance values, taken either individually or consecutively over 3
test intervals, are sufficiently restrictive to ensure that the reliability associated with the surveillance activity.is not significantly degraded beyond that obtained from the nominal specified interval.
4.0.3 The provisions of this specification set forth the criteria for determination of compliance with the OPERABILITY requirements of the Limiting Conditions for Operation.
Under this
- criteria, systems or components are assumed to be OPERABLE if the equipment, associated surveillance activities have been satisfactorily performed withi.n the specified time interval.
Nothing in this provision is to be construed as defining equipment, systems or components OPERABLE, found or known to be inoperable although still when such items are meeting the Surveillance Requirements.
4.0.4 This specification ensures that the surveillance activities associated with a
Limiting Condition for Operation have been performed within the specified time interval prior to entry into an OPERATIONAL MODE or other applicable condition.
The intent of this provision is to ensure that surveillance activities have been satisfactorily demonstrated on a
current basis as required to meet the OPERABILITY requirements of the Limiting Condition for Operation.

The surveillance requirement for measurement of the MTC at the beginning and near the end of each fuel cycle is adequate to confirm the MTC value since this coefficient changes slowly due i
principally to the reduction in RCS boron concentration associated with fuel burnup.
I 3/4.1.1.5 MINIMUM TEMPERATURE FOR CRITICALITY This specification ensures that the reactor will not be made critical with the Reactor Coolant System average temperature less than 541*F.
This limitation is required to ensure (1) the moderator temperature coefficient is within its analyzed temperature
- range, (2) the pressurizer is capable of being in an OPERABLE status with a steam I
- bubble, (3) the reactor pressure vessel is above its minimum RTUDT o
temperature, and (4) the protective instrumentation is within its normal operating range.
3/4.1.2 BORATION SYSTEMS The boron injection system ensures that negative reactivity control is available during each mode of facility operation.
The components required to perform this function include (1) borated water sources, (2) charging pumps, (3) separate flow paths, (4) boric acid transfer
- pumps, (5) associated heat tracing
- systems, and (6) an emergency 1
power supply from OPERABLE diesel generators.
l With the RCS average temperature above 200*F, e minimum of two separate and redundant boron injection systems are provided to ensure single functional capability in the event an assumed failure renders
{
one of the systems inoperable.
Allowable out-of-service periods l
ensure that minor component repair or corrective action may be
{
completed without undue risk to overall facility safety from 1
injection system failures during the repair period.
I With the RCS average temperature less than 200*F, Low Head Safety Injection pump may be used is lieu of the operable charging pump with a minimum open RCS vent of 3.14 square inches.
This will provide latitude for maintenance and ISI examinations on the charging system for repair or corrective action and will ensure that boration and makeup are available when the charging pumps are out-of-service.
An open vent insures that the RCS pressure will not exceed the shutoff head of the Low Head Safety Injection pumps.
MOV-1SI-890C is the Low Head Safety Injection Pump discharge isolation valve to the RCS coldlegs, the valve must be closed prior to reducing RCS pressure below the RWST head pressure to prevent draining into the RCS.
Emergency backup power is not required since this valve is outside containment and can be manually operated if
- required, this will allow the associated diesel generator to be taken j
out of service for maintenance and testing.

POWER DISTRIBUTION LIMITS BASES obtained by multiplying the RATED THERMAL POWER value by the appropriate fractional THERMAL POWER level.
The periodic updating of the target flux difference value is necessary to reflect. core burnup considerations.
Although it is intended that the plant will be operated with the AXIAL FLUX DIFFERENCE within the + 7% target band about the target flux difference, during rapid plant THERMAL POWER reductions, control rod motion will cause the AFD to deviate outside of the target band at reduced THERMAL POWER Levels.
This deviation will not affect the xenon redistribution sufficiently to change the envelope of peaking factors which may be reached on a subsequent return to RATED THERMAL POWER (with the AFD within the target band) provided the time duration of the deviation is limited.
Accordingly, a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> penalty o

For THERMAL POWER levels between 15% and 50% of RATED THERMAL POWER, deviations of the AFD outside of the target band are less significant.
The penalty of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> actual time reflects this reduced significance.
Provisions for monitoring the AFD on an automatic basis are derived from the plant process computer through the AFD Monitor Alarm.
The computer determines the one minute average of each of the OPERABLE excore detector outputs and provides an alarm message immediately if the AFD for at least 2 of 4 or 2 of 3 OPERABLE excore channels are outside the target band and the THERMAL POWER is greater than 90% of RATED THERMAL POWER.
During operation at THERMAL POWER levels between 50%
and 90% and between 15% and 50% RATED THERMAL POWER, the I
computer outputs an alarm message when the penalty deviation accumulates beyond the limits of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, respectively.

REACTOR COOLANT SYSTEM BASES The Surveillance Requirements for inspection of the steam generator that the structural integrity of this portion of the RCS tubes ensure will be maintained.
The program for inservice inspection of steam generator tubes is based on a modification of Regulatory Guide 1.83, Revision 1.
Inservice inspection of steam generator tubing is essential in order to maintain surveillance of the conditions of the tubes in the event that there is evidence of mechanical damage or progressive degradation due to
- design, manufacturing
- errors, or inservice conditions that lead to corrosion.
Inservice inspection of steam generator tubing also provides a means of characterizing the nature and cause of any tube degradation so that corrective measures can be taken.
The plant is expec'ad to be operated in a
manner such that the secondary coolant will be maintained within those parameter limits o
found to result in negligible corrosion of the steam generator tubes.
If the secondary coolant chemistry is not maintained within these parameter
- limits, localized corrosion may likely result in stress corrosion cracking.
The extent of cracking during plant operation would be limited by the limitation of steam generator tube leakage between the primary coolant system and the secondary coolant system 500 gallons per day per steam (primary-to-secondary leakage
=
generator).
Cracks having a primary-to-secondary leakage less than this limit during operation will have an adequate margin of safety to withstand the loads imposed during normal operation and by postulated accidents.
Operating plants have demonstrated that primary-to-l secondary leakage of 500 gallons per day per steam generator can
]
readily be detected by radiation monitors of steam generator blowdown.
Leakage in excess of this limit will require plant shutdown unscheduled inspection, during which the leaking tubes will be and an located and plugged.
Wastage-type defects are unlikely with the all volatile treatment (AVT) of secondary coolant.
However, even if a defect of similar type should develop in service, it will be found during scheduled inservice steam generator tube examinations.
plugging will be required of all tubes with imperfections exceeding the plugging limit which, by the definition of Specification 4.4.5.4.a is 40% of the tube nominal wall thickness.
Steam generator tube inspections of operating plants have demonstrated the capability to reliably detect degradation that has penetrated 20% of the original tube wall thickness.
Whenever the results of any steam generator tubing inservice inspection fall into Category C-3, these results will be reported to the Commission pursuant to Specification 6.6 prior to resumption of plant operation.
Such cases will be considered by the Commission on a requirement for analysis, case-by-case basis and may result in a
laboratory examinations,
- tests, additional eddy-current inspection, and revision of the Technical Specifications, if necessary.

REACTOR COOLANT SYSTEM BASES 3/4.4.6.1 LEAKAGE DETECTION SYSTEMS The RCS leakage detection systems required by this specification are provided to monitor and detect leakage from the Reactor Coolant Pressure Boundary.
These detection systems are consistent with the recommendations of Regulatory Guide 1.45, " Reactor Coolant Pressure Boundary Leakage Detection Systems."
3/4.4.6.2 OPERATIONAL LEAKAGE Industry experience has shown that while a limited amount of leakage is expected from the RCS, the unidentified portion of this leakage can be reduced to a
threshold value of less than 1 gpm.
This
~
threshold value is sufficiently low to ensure early detection of o
additional leakage.
The 10 gpm IDENTIFIED LEAKAGE limitation provides allowance for a limited amount of leakage from known sources whose presence will not interfere with the detection of UNIDENTIFIED LEAKAGE by the leakage detection systems.
The CONTROLLED LEAKAGE limitation restricts operation when the total flow supplied to the reactor coolant pump seals exceeds 28 gpm with the modulating valve in the supply line fully open at RCS pressures in excess of 2,000 psig.
This limitation ensures that in the event of a LOCA, the safety injection flow will not be less than assumed in the acci6ent analyses.
The total steam generator tube leakage limit of 1 gpm for all steam generators not isolated from the RCS ensures that the dosage contri-bution from the tube leakage will be limited to a small fraction of Part 100 limits in the event of either a steam generator tube rupture or steam line break.
The 1
gpm limit is consistent with the assumptions used in the analysis of these accidents.
The 500 gpd leakage limit per steam generator ensures that steam generator tube integrity is maintained in the event of a main steam line rupture or I
under LOCA conditions.

EMERGENCY CORE COOLING SYSTEMS (ECCS)

This initial surge of water into the core provides the initial cooling mechanism during large RCS pipe ruptures.
The limits on accumulator volume, boron concentration and pressure ensure that the assumptions used for accumulator injection in the accident, analysis are met.

PLANT SYSTEMS BASES 3/4.7.7 CONTROL ROOM EMERGENCY HABITABILITY SYSTEM The OPERABILITY of the control room ventilation system ensures that (1) the ambient air temperature does not exceed the allowable temperature for continuous duty rating for the equipment and instrumentation cooled by this system, and (2) the control room will remain habitable for operations personnel during and following all credible accident conditions.
The OPERABILITY of this system in conjunction with control room design provisions, is based on limiting the radiation exposure to personnel occupying the control room to 5 rem or less whole
- body, or its equivalent.
This limitation is consistent with the requirements of General Design Criteria 19 of Appendix "A", 10 CFR 50.
3/4.7.8 SUPPLEMENTAL LEAK COLLECTION AND RELEASE SYSTEM (SLCRS)
The OPERABILITY of the SLCRS provides for the filtering of postulated radioactive effluents resulting from a Fuel Handling Accident (FHA) and from leakage of LOSS OF COOLANT ACCIDENT (LOCA) activity from systems outside of the Reactor Containment building, such as Engin-5 eered Safeguards Features (ESF) equipment, prior to their release to the environment.
This system also collects potential leakage of LOCA activity from the Reactor Containment building penetrations into the contiguous areas ventilated by the SLCFS except for the Main Steam Valve Room and Emergency Air Lock.
The operation of this system was assumed in calculating the postulated offsite doses in the analysis for a
FHA.
System operation was also assumed in that portion of the i
Design Basis Accident (DBA) LOCA analysis which addressed ESF leakage following the LOCA, however, no credit for SLCRS operation was taken in the DBA LOCA analysis for collection and filtration of Reactor Containment building leakage even though an unquantifiable amount of contiguous area penetration leakage would in fact be collected and filtered.
Based on the results of the analyses, the SLCRS must be OPERABLE to ensure that ESF leakage following the postulated DBA LOCA j
and leakage resulting from a FHA will not exceed 10 CFR 100 limits.
3/4.7.9 SEALED SOURCE CONTAMINATION
}
The limitations on sealed source removable contamination ensure that the total body or individual organ irradiation does not exceed allow-able limits in the event of ingestion or inhalation of the source material.
The limitations on removable contamination for sources requiring leak testing, including aloha emitters, is based on 10 CFR 70.39(c) limits for plutonium.
Leakage of sources excluded from the l
requirements of this specification represent less than one maximum permissible body burden for total body irradiation if the source material is inhaled or ingested.

The minimum water depth-is consistent with the assumptions of the accident analysis.
~3/4.9.12 and 3/4.9.13 FUEL BUILDING VENTILATION SYSTEM The limitations on the storage pool ventilation system ensure that all-radioactive material released from an irradiated fuel assembly will be filtered through the HEPA filters and charcoal adsorber prior to discharge to the atmosphere.
The OPERABILITY of this system _and the resulting iodine removal capacity are consistent with the assumptions of the accident analysis.
The spent fuel pool area ventilation system is non-safety related and only recirculates air through the fuel building.
The SLCRS portion of the ventilation system is safety-related and continuously filters the fuel building exhaust air.
'This maintains a
