l O 'l O l NOTE The summary statenents contained in this section provide the bases for the specifications of Sections 3.0 and 4.0 and are not considered a part of these technical specifications as provided in 10 CFR 50.36. ! 3 i

3/4.0 APPLICABILITY n BASES The specifications of this saction provide the general requirements applicable to each of the Limiting Cont:ons for Operation and Surveil-lance Requirements within Section 3/4. l 3.0.1 This specification defines the applicability of each specifica- l tion in terms of defined OPERATIONAL MODES or other specified conditions l 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 whose occurrence would violate the intent of the specification. For example, Specification 13.5.11 calls for each Reactor Coolant System

 \c 'j   core flooding tank to be OPERABLE and provides explicit ACTION require-ments when one tank is inoperable. Under the tenns of Specification 3.0.3, if more than one tank is inoperable, the facility is required to be in at least HOT STANDBY within 1 hour and in COLD SHUTDOWN within the following 30 hours.
                                                   \

3.0.4 This' specification provides that entry into an OPERATIONAL l 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. The intent of this provision is to ensure that facility operation is not initiated with either required equipment or systems inoperable or other specified limits being exceeded. Exceptions to this provision have'been provided for a limited number of specifications when startup with inoperable equipment would not affect plant safety. The:e exceptions are stated in the ACTION statements of l the appropriate specifications. l ( B&W-STS B 3/4 0-1 June 1,1976 i

APPLICABILITY v BASES 4.0.1 This specification provides that surveillance activities necessary to insure the Limiting Conditions for Operation are met and 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 conditions are provided in the individual Surveillence Requirements. 4.0.2 The provisions of this specification provide allowable toler-ances 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 phrase "at least" associated with a surveillance frequency does not negate this allowable tolerance value and permits the performance of more frequent surveillance activities. 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 signifi- " cantly 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 Operations. Under this criteria, equipment, systems or components are assumed to be OPERABLE if the associated surveillance activities have been satisfactorily performed within the specified time interval. Nothing in this provision is to be construed as defining equipment, systems or components OPERABLE, when such items are found or known to be inoperable although still 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. i ( BW-STS B 3/4 0-2 January 1, 1977

O L' APPLICABILITY O BASES Under the te :,s of this specification, for example, during initial plant startup or rollowing extended plant outages, the applicable surveillance activities must be perfonned within the stated surveillance interval prior to placing or returning the system or equipment into OPERABLE status. 4.0.5 This specification ensures that inservice inspection of ASME Code Class 1,'2 and 3 components and inservice testing of ASME Code Class 1, 2 and 3 pumps and valves will be performed in accordance with a period-ically updated version of Section XI of the ASME Boiler and Pressure Vessel Code and Addenda as required by 10 CFR 50.55a. Relief from any of the above requirements has been provided in writing by the Commission and is not a part of these technical specification. Under the terms of this specification, the more restrictive require-ments of the Technical Specifications take precedence over the ASME Boiler and Pressure Vessel Code and applicable addenda. For example, the requirements of Specification 4.0.4 to perform surveillance activities prior to entry into an OPERATIONAL MODE or other specified applicability condition takes prededence over.the ASME Boiler and Pressure Vessel '1 Code provision which allows pumps to be tested up to one week after return to normal operation. And for example, the Technical Specification definition of OPERABLE does not grant a grace period before a device that is not capable of performing its specified function is declared inoperable and takes precedence over the ASME Boiler and Pressure Vessel provision which allows a valve to be incapable of perfortning its specified function for up to 24 hours before being declared inoperable.

3/4.1.1 B0 RATION CONTROL 3/4.1.1.1 SHUTDOWN MARGIN A sufficient SHUTDOWN MARGIN ensures that 1) the reactor can be made subcritical from all operating conditions, 2) the reactivity transients associated with postulated accident conditions are controllable within acceptable limits, and 3) the reactor will be maintained sufficiently subcritical to preclude inadvertent criticality in the shutdown condition. During Modes 1 and 2 the SHUTDOWN MARGIN is known to be within limits if all control rods are OPERABLE and withdrawn to or beyond the insertion i limits. SHUTDOWN MARGIN requirements vary throughout core life as a function of fuel depletion, RCS boron concentration and RCS T a The most atnoT8a.d operating

The surveillance require-ment for measurement of the MTC each fuel cycle are adequate to confirm l the MTC value-since this coefficient changes slowly due principally to the reduction in RCS boron concentration assaciated with fuel burnup. The confinnation that the measured MTC value is within its limit provides assurance that the coefficient will be maintained within acceptable values l throughout each fuel cycle. l B&W-STS B 3/4 1-1 June 1, 1976 l \

         /4.1.2 80 RATION 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) makeup or DHR pumps, 3) separate flow paths, 4) boric acid pumps, 5) associated heat tracing systems, and 6) an emergency power suppl" from OPERABLE emergency busses.

With the RCS average temperature above 200 F, a minimum of two v separate and redundant borori 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 ensure that minor component repair or corrective action may be completed without undue risk to overall facility safety from injection system failures during the repair period. The boration. capability of either system is sufficient to provide a SHUTDOWN MARGIN from expected operating conditions of 1.0 %Ak/k after xenon decay and cooldown to 200*F.

OPERABILITY of the control rod position indicators is required to determine control rod positions and thereby ensure compliance with the control rod alignment and insertion i limits. The ACTION statements which permit limited variations from the basic requirements are accompanied by additional restrictions which ensure that the original design criteria are met. For example, misalignment of a I safety or regulating rod requires a restriction in THERMAL POWER. In addition, those accident analyses affected by a misaligned rod are l reevaluated to confirm that the results remain valid during future opera tion. The position of a rod declared inoperable due to misalignment should not be included in computing the average group position for determining the OPERABILITY of rods with lesser misalignments.

In addition, the above criteria must be met in order to meet the assumptions used for the loss-of-coolant accidents.

The power-imbalance envelope defined in Figures (3.2-1,aM- 3.2-2),awa 3.1-3, and the insertion limit curves, Figures (3.1-1, 3.1-2, 3.1-3, 3.1-4,aM 3. -spa 3.i 3.1 5), are based on LOCA analyses which have defined the maximum linear heat rate such that the maximurr. clad temperature will not exceed the Final Acceptance Criteria of 2200 F fcllowing a LOCA. Operation outside of the power-imbalance envelope alone does not constitute a situation that would cause the Final Acceptance Criteria to be exceeded should a LOCA occur. The power-imbalance envelope represents the boundary of operation limited by the Final Acceptance Criteria only if the control rods are at the inser-

(,) BASES 3/4.3.3 MONITORING INSTRUMENTAT'.0N 3/4.3.3.1 RADIATION MONITORING '.!NSTRUMENTATION 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 initiated when the radiation level trip setpoint is exceeded.

3/4.3.3.2 INCORE DETECTORS The OPERABILITY of the incore detectors ensures that the measurements obtained from use of this system accurately represent the spatial neutron flux distribution of the reactor core. See Bases Figures 3-1 and 3-2 for examples of acceptable minimum incore detector arrangements. 3/4.3.3.3 SEISMIC INSTRUMENTATION ( D I' The OPERABILITY of the seismic instrumentation ensures that suffi- cient capability is available to promptly determine the magnitude of a seismic event so that the response of those features important to safety may be evaluated. This capability is required to permit comparison of the measured response to that used in the design basis for the facility to determine if plant shutdown is required pursuant to Appendix "A" of l 10 _ , -CFR Part 100. -Tl.6 ia m u= n weivo is consiscenc wico J.c . cuv...oc aun m . _ _ , _ _ . . . i uns

With one reactor coolant pump not in operati:n in one or both loops, THERMAL POWER is restricted by the Nuclear Overpower Based on RCS Flow and AXIAL POWER IMBALANCE and the Nuclear Overpower Based on Pump Monitors trip, ensuring that the DNBR will be maintained above (1.22/1.307 at the maximum possible THERMAL POWER for the number of reactor coolant pumps in operation-ci th: Ical quality at thc pelat of Tiniasm DNOR equal te (22/10)%, whicheser is acre re trictisc. A single reactor coolant loop proviaes sufficient heat removal capability for removing core decay heat while in HOT STANDBY; however, single failure considerations require placing a DHR loop into operation in the shutdown cooling mode if component repairs and/or corrective actions cannot be made within the allowable out-of-service time. (m 3/4.4.2 and 3/4.4.3 SAFETY VALVES The pressurizer code safety valves operate to prevent the RCS from being pressurized above its Safety Limit of.{2750) psig.

In the event that no safety valves are OPERABLE, an operating DHR loop, con-nected to the RCS, provides overpressure relief capability and will prevent RCS overpressurization. , Durir.g operation, all pressurizer code safety valves must be OPERABLE to prevent the RCS from being pressurized above its safety limit of

        $2750)psig. The combined relief capacity of all of these valves is greater than the maximum surge rate resulting from any transient.

o (A fx REACTOR COOLANT SYSTEM v ! \ V BASES 3/4.4.4 PRESSURIZER A steam bubble in the pressurizer ensures that tne RCS is not a hydraulically solid system and is capoble of accommodating pressure surges during operation. The steam bubble also protects the pressurizer code safety valves and power operated relief valves against water relief. The low level limit is based on providing enough water volume to prevent a pressurizer low level or a reactor coolant system low pressure condition that would actuate the Reactor Protection System or the Engineered Safety Feature Actuation System as a result of a reactor scram. The high level limit is based on providing enough steam volume to prevent a pressurizer high level as a result of any transient. The power operated relief valves and steam bubble function to relieve RCS pressurc during all design transients. Operation of the power operated relief valves minimizes the undesirable opening of the spring-loaded pressurizer code safety valves. O 3/4.4.5 STEAM GENERATORS The Surveillance Requirements for inspection of the steam generator tubes ensure that the structural integrity of this portion of the RCS 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 expected to be operated in a manner such that the

  • secondary coolant will be maintained within those chemistry limits found to result in negligible corrosion of the steam generator tubes. If the .

secondary coolant chemistry is not maintained within these chemistry l limits, localized corrusion 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 systen and the secondary coolant system (primary-to-secondary leakage = 1 GPM). Cracks having a primary-to-secondary leakage less than this limit during operation will have an adequate margin of safety w withstand the loads Uj B&W-STS B 3/4 4-2 June 1,1976

pp REACTOR COOLANT SYSTEM A Q BASES imposed during normal operation and by postulated accidents. Operating plants have demonstrated that primary-to-secondary leakage of 1 GPM can be detected by monitoring the secondary coolant. Leakage in excess of this limit will require plant ',nutdown and an unscheduled inspection, during which the leaking tubes will be located and plugged. Wastage-type defects are unlikely with proper chemistry treatment of I the secondary coolant. However, even if a defect should develop in service, it will be found during scheduled inservice steam generator tube examinations. Plugging will be required for (40B of the tube nominal wall thickness. Steam generator tube inspections of operating plants have demonstrated the capability to reliably detect degradation that has pene-trated 20% of the original tube wall thickness. Whenever the results of any steam generator tub.ing inservice inspec-tion fall into Category C-3, these results g,ijl be prnmptly reported to the Commission pursuant to Specification 6.s.. prior to resumption of plant operation. Such cases will be considered by the Commission on a case-by-case basis and may result in a requirement for analysis, laboratory % examinations, tests, additional eddy-current inspection, and revision of the Technical Specifications, if necessary.

' Therefore, the presence of any PRESSURE BOUNDARY LEAKAGE requires the unit to be promptly placed in COLD SHUTDOWN. Industry experience has shown that, while a limited amount of leakage { is expected from the RCS, the UNIDENTIFIED LEAKAGE portion of this can be , i reduced to a threshold value of less than 1 GPM. This threshold value is v sufficiently low to ensure early detection of additional leakage.  ; i The total steam generator tube leakage limit of 1 GPM for all steam generators ensures that the dosage contribution from tube leakage will be limited to a small fraction of Part 100 limits in the event of either a steam generator tube ru&ture or steam line break. The 1 GPM limit is consistent with the assumptions used in the analysh of these accidents.

Maintaining the chemistry within the Steady State Limits shown on Table 3.4-1 provides adequate corrosion protection to ensure the structural integrity of the Reactor Coolant System over the life of the l plant. The associated effects of exceeding the oxygen, chloride and fluoride limits are time and temperature dependent. Corrosion studies 1 show that operation may be continued with contaminant concentration  ! levels in excess of the Steady State Limits, up to the Transient Limits, l for the specified limited time intervals without having a significant i effect on the structural integrity of the Reactor Coolant System. The ' time interval permitting continued operation within the restrictions of the Transient Limits provides time for taking corrective actions to restore the contaminant concentrations to within the Steady State Limits. The surveillance requirements provide adequate assurance that con-4, centrations in excess of the limits will be detected in sufficient tima to take corrective action. 3/4.4.8 SPECIFIC ACTIVITY The limitations on the specific activity of the primary coolant ensure that the resulting 2 hour doses at the site boundary will not exceed an appropriately small fraction of the Part 100 limit following a steam generator tube rupture accident in ccajunction with an assumed steady state primary-to-secondary scnam generator leakage rate of 1.0 GPM.

During heatup and cooldown, the rates of temperature and pressure changes are limited so that the maximum speci-fied heatup and cooldown rates are consistent with the design assumptions and satisfy the stress limits for cyclic operation. During heatup, the thermal gradients in the reactor vessel wall produce thermal stresses which vary from compressive at the inner wall to l tensile at the outer wall. These thermal induced compressive stresses tend to alleviate the tensile stresses induced by the internal pressure. Therefore, a pressure-temperature curve based on steady state conditi ns (i.e., no thermal stresses) represents a lower bound of all similar curves for finite heatup rates when the inner wall of the vessel is treated as the governing location.

The thennal gradients estab-lished during heatup produce tensile stresses at the outer wall of the  ! vessel. These stresses are additive to the pressure induced tensile stresses which are already present. The thermal induced stresses at the outer wall of the vessel are tensile and are dependent on both the rate cf heatup and t."e tire along the heatup ramp; therefore, a lower bound curve similar to that described for the heatup of the inner wall cannot i be defined.

( The inspection programs for ASME Code Class 1, 2 and 3 components, except steam generator tubes, ensure that the structural integrity of these components will be maintained at an acceptable level throughout the life of the plant. To the extent applicable, the inspection program for these components is in compliance with Section XI of the ASME Boiler and Pre:;sure Vessel Code. The internals vent valves are provided to relieve the pressure generated by steaming in the core following a LOCA so that the core remains sufficiently covered. Inspection and manual actuation of the internals vent valves 1) ensure OPERABILITY, 2) ensure that tha valves are not stuck open during normal operation, and 3) demonstrates that the valves t,q;in t Op:n :nd are fully open at the forcey equivalent to the differential pressures assumed in the safety analysis.

QLs b BASES 3/4.5.1 CORE FLOODING TANKS 1 The OPERABILITY of each core flooding tank ensures that a sufficient volume of borated water will be imediately forced into the reactor vessel in the event the RCS pressure falls below the pressure of the tanks. This initial surge of water into the vessel provides the initial cooling mechanism during large RCS pipe ruptures. The limits on volume, boren concentration and pressure ensure that the assumptions used for core flooding tank injection in the safety I analysis are met. The tank power operated isolation vaives are considered to.be

                " operating bypasses" in the context of IEEE Std. 279-1971, which requires that bypasses of a protective function be removed automatically whenever permissive conditions are not met. In addition, as these tank isolation valves fail to meet single failure criteria, removal of power to the valves is required.

The limits for operation with a core flooding tank inoperable for l l any reason except an isolation valve closed minimizes the time exposure l < of the plant to a LOCA event occurring concurrent with failure of an additional tank which may result in unacceptable peak cladding tempera-tures. If a closed isolation valve cannot be imediately opened, the full capability of one tank is not available and prompt action is required to place the reactor in a mode where this capability is not required. 1 l 1 1

                              'F ensures that sufficient emergency core cooling capability will be available in the event of a LOCA assuming the loss of one subsystem through any single failure consideration. Either subsystem operatNg in conjunction with the core flooding tanks is capable of suppb g sufficient core cooling to maintain the peak cladding tempera-tures within acceptable limits for all postulated break sizes ranging from the double ended break of the largest RCS cold leg pipe downward.

In addition, each ECCS subsystem provides long term core cooling capability in the recirculation mode during the accident recovery period. 3so With the RCS temperature below +30&)'F, one OPERABLE ECCS subsystem is acceptable without single failure consideration on the basis of the stable reactivity condition of the reactor and the limited core cooling requirements. The Surveillance Requirements provided to ensure OPERABILITY of each component ensures, that, at a minimum, the assumptions used in the l'n) safety analyses are met and that subsystem OPERABILITY is maintained. Power is required to be removed from any valve which fails to meet single failure criteria. The decay heat removal system leak rate # ( surveillance requirements assure that the leakage rates assumed for the system during the recirculation phase of the low pressure injection will not be exceeded. 3/4.5.4 BORATED WATR STORAGE TANX The OPERABILITY ef the barated water storage tank (BWST) as part of the ECCS ensures that a safficient supply of borated water is available for injection by the ECCS in the event of a LOCA. The limits on BWST minimum volume and boron concentration ensure that 1) sufficient water is available within containment to permit recirculaticn cooling flow to the core, and 2) the reactor will remain subcritical in the cold condi-t tion following mixing of the BWST and the RCS water volumes with all control rods inserted except for the most reactive control assembly. These assumptions are consistent with the LOCA analyses.

RH %C il.l A RY 3/4.9.7 CMNE TRAVEL - C""NT IU~L ST0"",C" BUILDING The restriction on movement of loads in excess of the nominal weight of a fuel and control rod assembly and associated handling tool over other fuel assemblies in the storage poul ensures that in the event this load is dropped (1) the activity release will be limited to that contained in a single fuel assembly, and (2) any possible distortion of fuel in the storage racks will not result in a critical array. This assumption is consistent with the activity release assumed in the accident analyses. 3/4.9.8 COOLANT CIRCULATION

The requirement that at least one decay heat removal loop be in 5 operation ensures that (1) sufficient cooling capacity is available to remove decay heat and maintain the water in the reactor pressure vessel below 140*F as required during the REFUELING MODE, and (2) sufficient coolant circulation is maintained through the reactor core to minimize the effect of a baron dilution incident and prevent boron stratification. . , . _ , , . . , . , c.-,,- -o y w , }$
