The Boron Injection System ensures that negative rea(tivity control is W available during each mode of facility operation. The components required to

  • With the RCS in MODES 1, 2, or 3, a minimum of two boron injection flow paths are required to ensure single functional capability in the event an Q assumed failure renders one of the flow paths inoperable. The boration

The limitation for a maximum of one centrifugal charging pump to be OPERABLE and the Surveillance Requirement to verify all charging pumps except the required OPERABLE pump to be inoperable in MODES 4, 5, and 6 provides assurance that a mass addition pressure transient can De relieved by operation of a single PORY or an RHR suction, relief valve.

As a result of this, only one boron injection system is available. . This is acceptable on the basis of the stable reactivity condition of the reactor, the emergency power supply requirement for the OPERABLE charging pump and the additional restrictions prohibiting CORE ALTERATIONS and positive reactivity changes in the event the singie injection system becomes inoperable.

3/4.1.3 MOVABLE CONTROL ASSEMBLIES The specifications of this section ensure that: (1) acceptable power distri-bution limits are maintained, (2) the minimum SHUTDOWN MARGIN is maintained, and (3) the potential effects of rod misalignment on associated accident analyses are limited. 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 limits. Verification that the Digital Rod Position Indicator agrees with the demanded position within 1 12 steps at 24, 48, 120, and 228 steps withdrawn for the Control Banks and 18, 210, and 228 steps with-crawn for the Shutdown Banks provides assurances that the Digital Rod Position Indicator is operating correctly over the full range of indication, Since the Digital Rod Position Indication System does not indicate the actual shutdown rod l position between 18 steps and 210 steps, only points in the indicated ranges .

are picked for ve ification of agreement with demanded position.

l 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. ' Misalignment of a red requires measurement

, of peaking factors and a restriction in THERMAL POWER. These restrictions pro-

! vide assurance of fuel rod integrity during continued operation. In addition, j those safety analyses affected by a misaligned rod are reevaluated to confirm I

BASES The specifications of this section provide assurance of fuel integrity during Condition 1 (Normal Operation) and !! (Incidents of Moderate Frecuency) events by: (1) maintaining the minimum DNBR in the core greater than or equal to 1.30 during normal operation and in short-term transients, and (2) limiting the fission gas release, fuel pellet temperature, and cladding mechanical properties to within assumed design criteria. In addition, limiting the peak linear power density during Condition I events provides assurance that the initial conditions assumed for the LOCA analyses are met and the ECCS acceptance.

criteria limit of 2200*F is not exceeded.

The definitions of certain hot channel and peaking factors as used in these specifications are as follows:

F0 (Z) Heat Flux Hot Channel Fletor, is defined as the maximum local heat flux on the surface of a fuel rod at core elevation I divided by the average fuel rod heat flux, allowing for menufacturing tolerances on fuel pellets and rods; Nuclear Enthalpy Rise Hot Cnannel Factor, is defined as the ratio of Fh*

the integral of linear power along the rod with the highest integrated power to the average rod power; and

^

F Radial Peaking Factor, is defined as the ratio of peak power density

Target flux difference is determined at equilibrium xenon conditions.

The full-length rods may be positiened within the core in accordance with their respective insertion limits and should be inserted near their normal position for steady-state operation at high power levels. The value of the target flux difference obtained under these. conditions divided by the fraction of RATED THERMAL POWER is the target flux difference at RATED THERMAL POWER for the associated core burnup conditions. Target flux differences for other THERMAL POWER levels are 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 AFD within the target band required by Specification 3.2.1 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.

REACTIVITY CONTROL SYSTEMS BASES BORAT10N CONTROL 3/4.1.1.3 MODERATOR TEMPERATURE COEFFICIENT (Continued)

The Surveillance Requirements for measurement of the MTC at the beginning and near the end of the fuel cycle are adequate to confirm that the MTC remains within its limits since this coefficient changes slowly due

. principally to the reduction in RCS boron concentration associated with fuel burnup.-

3/4.1.1.4 HINIMUM TEMPERATURE FOR CRITL(AllTY This specification ensures that the reactor will not be made critical

- with the Reactor Coolant System average temperature less than 551' F. This limitation is required to ensure: (1) the moderator temperature coefficient is within its analyzed temperature range, (2) the trip instrumentation is within its normal operating range,-(3) the pressurizer is capable of being in an OPERABLE sta is with a steam bubble, and (4) the reactor vessel is above its minimum RTnf temperature.

- 3/4.1.2 BORAT10N SYSTEMS The Boron Injection System ensures that negative reactivity control is available during each mode of facility operation. The components recuired to perform this functinn include: (1) borated water sources, (2) charging pumps, (3) separate flow paths, (4) boric acid transfer pumps, and (5) an emergency power supply from OPERABLE diesel generators.

With the RCS in-MODES 1, 2, or 3, a minimum of two boron injection flow paths are required to ensure single functional capability in the event an assumed failure renders one of the flow paths inoperable. The boration capability of either flow path is sufficient to provide a SHUTDOWN MARGIN as specified in the CORE OPERATING LIMITS REPORT from expected operating i conditions after xenon decay and cooldown to 200' F. The maximum expected boration capability requirement occurs at E0L from full power equilibrium xenon conditions and requires 22,000 gallons of 7000 ppm borated water from the boric acid storage tanks or a minimum contained volume of 477,000 gallons of 2000 ppm borated water from the refueling water storage tank (RWST). ,

The limitation for a maximum of one centrifugal charging pump to be OPERABLE'and the Surveillance Requirement to verify all charging pumps except the required OPERABLE pump to be inoperable in MODES 4, 5, and 6 provides

- assurance that a mass addition pressure transient can be-relieved by operation of a single PORV or an RHR suction relief valve. .

As a result of this, only one boron injection system is available. This

+ is acceptable on the basis of the stable reactivity condition of the reactor, the-emergency power supply requirement for the OPERABLE charging pump and the additional restrictions prohibiting CORE ALTERATIONS and positive reactivity i changes in the event the single injection system becomes inoperable.

BASES 2/.LL 2 BORAT10N SYSTEMS (Continued)

The boron capability required below 200' F is sufficient to provide a SHUTDOWN MARGIN as specified in the CORE OPERATING LIMITS REPORT-after xenon decay and cooldown from 200* f to 140' f. This condition requires a minimum contained volume of 6500 gallons of 7000 ppm borated water from the boric acid storage tanks or a minimum contained volume of 24,500 gallons of 2000 ppm -

borated water frum the RWST.

2 The contained water volume limits include allowance for water not available because of discharge line location and other physical >

characteristics.

The limits on contained water volume and boron concentration of the RWST also ensure a pH value of between 8.5 and 11.0 for the solution recirculated within containment after a LOCA. This pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic stress corrosion on mechanical systems and components.

d The OPERABILITY of one Boron injection System uring REFUELING ensures ,

that this system is available for reactivity contr' lile in MODE 6.

The limitations on OPERABillTY of isolation provisions for the Baron Thermal Regeneration System-and the Reactor Water Makeup System in Modes 3, 4, 5, and 6 ensure that the boron dilution flow rates cannot exceed the value assumed in the transient analysis.

3/4.1.3 MOVABLE CONTROL ASSEMBLIES The specifications of this section ensure that: (1) acceptable power distribution limits are maintained, (2) the minimum SHVIDOWN MARGIN is maintained, and (3) the potential effects of rod misalignment on associated .

accident analyses are limited. OPERABILiiY of the control rod position i indicators is required to determine control rod positions and thereby ensure compliance with the control rod alignment and insertion limits. Verification that the Digital Rod Position Indicator agrees with the demanded position within 12 steps at 24, 48, 120, and 228 steps withdrawn for the Control Banks and 18, 210, and 228 steps withdrawn for the Shutdown Banks provides assurances that the Digital Rod Position Indicator is operating correctly over the full range of indication. Since the Digital Rod Position _ indication System does not indicate the actual shutdown rod position between 18 steps-and 210 steps, only points in the indicated ranges are picked for verification of agreement with demanded-position.

The ACTION state;nents which permit limited variations from the basic requirements are accompanied by additional restrictions which ensure that the original design criteria are met. Misalignment of a rod requires measurement of peaking factors and a restriction in THERMAL POWER. These restrictions provide assurance of fuel rod integrity during continued operation. In addition, those safety analyses affected by a misaligned rod are reevaluated to confirm that the results remain valid during future operation.

BASES I

The specifications of this section provide assurance of fuel integrity during Condition 1 (Normal Operation) and 11 (Incidents of Moderate frequency) i events by: (1) maintaining the minimum DNBR in the core greater than or equal i to 1.30 during normal operation and in short-term transients, and (2) limiting j the fission gas release, fuel pellet temperature, and cladding mechanical

[ properties to within assumed design criteria. In addition, limiting the peak i linear power density during Condition i events provides assurance that the

acceptance criteria limit of 2200* f is not exceeded. ,

these specifications are as follows:

l fq(Z) Heat Flux Hot Channel factor, is defined as the maximum local heat j flux on the surface of a fuel rod at core elevation Z divided by the i average fuel rod heat flux, allowing for manufacturing tolerances on i fuel pellets and rods; 1

F ",,n Nuclear Enthalpy Rise Hot Channel factor, is defined as the ratio of j the integral of linear power along the rod with the highest 1 integrated power to the average rod power; and F,,(Z ) Radial Peaking factor, is defined as the ratio of peak power density to average power density in the horizontal plane at core elevation Z.

3/4.2.1 AXI Al FLUX _J)1FFERENCE i The limits on AXIAL FLUX DIFFERENCC (AFD) assure that the Fn (Z) upper

, bound envelope of the fn limit specified in the CORE OPERATING LihlTS REPORT

(COLR) times the normalized axial peaking factor is not exceeded during either l- -normal operation or in the event of xenon redistribution following power changes.

Target flux difference is determined at equilibrium xenon conditions.

The full-length rods may be positioned within the core in accordance with their respective insertion limits and should be inserted near their normal position for steady-state operation at high power levels. The value of the target flux difference obtained under these conditions divided by the fraction of RATED 1HERMAL POWER is the target flux dif ference at RATED THERMAL POWER for the associated core burnup conditions. Target flux differences for other THERMAL POWER levels are 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 intendcd that the plant will be operated with the AFD within the target band required by Specification 3.2.1 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 SEABROOK - UNIT 1 B 3/4 2-1 Amendment'No.

POWER DISTRIBUTION LIMITS BASES 3/4.2.1 AX1AL FLUX DIFFERENCE (Continued) 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-hour penalty deviation limit cumulative during the previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is provided for operation outside of the target band but within established limits while at THERMAL POWER levels between 50% and 90% of RATED THERMAL POWER. 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 1-minute average of each of the OPERABLE excore detector

, outputs and provides an alarm message immediately if the AFD for two or more

OPERABLE excore channels are outside the target band and the THERMAL POWER is j 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 computer outputs an alarm message when the penalty deviation accumulates beyond the limits of I hour and 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, respectively.

' 3/4.2.2 and 3/4.2.3 HEAT FLUX HOT CHANNEL FACTOR and NUCLEAR ENTHALPY-RISE HOT CHANNEL FACTOR The limits on heat flux hot channel factor and nuclear enthalpy rise hot channel factor ensure that: (1) the design limits on peak local power density and minimum DNBR are not exceeded and (2) in the event of a LOCA, the peak

fuel clad temperature will not exceed the 2200* F ECCS acceptance criteria i limit.

Each of these is measurable but will normally only be determined periodically as specif_ied in Specifications 4.2.2 and 4.2.3. This periodic surveillance is sufficient to ensure that the limits are maintained provided:

a. Control-rods in a single group move together with no individual rod insertion differing by more than i 12 steps, indicated, from the group demand position; i b. Control rod groups are sequenced with overlapping groups as described in Specification 3.1.3.6;
c. The control rod insertion limits of Specifications 3.1.3.5 and 3.1.3.6 are maintained; and

IV. Safety Evaluation of Proposed Chanaes I The current Technical Specification method of controlling reactor physics parameters to ensure confonnance to 10 CFR 50.36 (which requires the lowest functional performance levels acceptable for continued safe operation) is to specify the values determined to be within the acceptable criteria using an NRC-approved methodology for calculating the parameter. The methodologies for determining these cycle-specific parameter limits specified in proposed Technical Specification Section 6.8.1.6 have been reviewed and approved by the NRC and are consistent i with the-applicable analyses presented in the Updated Final Safety .

Analysis Report (FSAR).

lhe removal of cycle specific parameter limits from the Technical Soecifications has no impact upon plant operation or safety. No ,

safety related equipment, safety function, or plant o)erations will be-altered as a result of this proposed change. Since tie applicable FSAR i limits will be maintained and the proposed Technical Specifications will  !

require operation within the cycle-specific parameter limits determined by _specifically identified NRC-approved methodologies, this proposed ,

change-is administrative in nature. The required actions to be taken if limits are violated are not affected by the proposed Technical Specification changes nor are the required surveillance requirements.

l The proposed Technical Specification changes will control the cycle specific parameters within the acceptance criteria and assure conformance-to 10 CFR 50.36 by using the approved methodology instead of sper.ifyi'ig Technical Specification values. The COLR will document the

  • specific parameter limits resulting from cycle design calculations, including mid-cycle or other revisions to parameter values. Therefore, the proposad d ange is in conformance with the requirements of 10 CFR >

50.36..

Any changes to the COLR will be made in accordance with the provisions of 10 CFR 50.59. From cycle to cycle, the COLR will be revised such that the appropriate cycle specific parameter limits for ,

the applicable cycle will a) ply. Technical Specifications will not be '

~

changed, thus eliminating tie associated administrative burden.

f V. Determination of Sionificant Hazards for Proposed Chanaes  ;

Pursuant to 10 CFR 50.91, New Hampshire Yankee has determined that operation of the facility in accordance with the proposed License Amendment Request does not involve any significant hazards considerations as defined by NRC regulations in 10 CFR 50.92. The following discussion describes how the proposed amendment satisfies each 4

of the three standards of 10 CFR 50.92(c).

1) The proposed change does not involve a significant increase in the probability or consequences of an accident previcasly evaluated. ,

The removal of cycle specific parameter limits from the Seabrook Station Technical Specifications has no influence or impact on the 1 probability or consequences of any accident previously evaluated.

The cycle specific parameter limits, although not in Technical Specifications, will be followed in the operation of Seabrook Station. The proposed Technical Specification changes do not ,

effect the actions which must be taken if the cycle-specific

< parameter limits are exceeded nor do they affect the surveillance i reouirements associated with these limits.

Future core reload designs will be supported by a 10 CFR 50.59 evaluation which will examine each accident analysis addressed in i the Updated Final Safety Analysis Report (FSAR) with respect to .

, changes in cycle-specific parameter limits to ensure that the

. reload design itbounded by previously accepted analyses. This examination - which will be performed per the requirements of 10 CfR 50.59, ensures that future core reload designs will not involve a significant increase in the probability or consequences of an accident previously evaluated.

2) Tho' proposed change does not create the possibility of a new or

- a different kind of accident from any accident previously evaluated.

As stated above the removal of the cycle specific parameter limits has no-influence or impact, nor does it contribute in any way to the probability or consequences of an accident. No safety related equipment, safety function, or plant operations will be. altered as a result of this proposed change. The cycle specific parameter limits are calculated using the.NRC-approved methods and submitted -

to the NRC to allow the Staff to continue to trend the values of these limits. The proposed Technical Specifications will require operation within the cycle-specific parameter limits. The proposed Technical Specification changes do not affect the actions which must be taken if the cycle-specific parameter limits are exceeded nor do they affect the surveillance requirements associated with these limits.

Therefore,' the proposed amendment does not in any way create the 4 possibility of a new or dif ferent kind of accident from any accident previously evaltated.

3) The proposed amendment does not result in a significant' reduction in the margin of safety.

The margin of safety is not affected by the removal of 4 cycle-specific parameter limits from the Technical Specifications.

The margin of safety provided by current Technical Specifications remaint unchanged.- Surveillance requirements exist to monitor the values of these cycle-specific parameter limits. The proposed Technical Specification changes require operation within the .

cycle-specific parameter limits which are determined using  :

NRC-approved reload design methodologies.

The development of the cycle specific parameter limits for future reload designs will continue to utilize only those methods described in NRC-approved documentation and identified in aroposed Technical Specification Section 6.8.1.6. In addition, eac1 future i

reload design will involve a 10 CFR 50.59 safety evaluation to assure that operation of the unit within the-cycle-specific parameter limits will not involve a significant reduction in a margin of safety.

Therefore..the )roposed changes are administrative in nature and

, do not impact tie operation of the Seabrook Station in a manner that involves a reduction in the margin of safety.

The Commission has provided guidance concerning the application of the standards for determining whether a significant hazards consideration exists. This guidance (51 FR 7750) includes examples of the type of amendments.that are considered not likely to involve significant hazards considerations. The change-proposed is similar to the examples of administrative changes identified in 51 FR 7750. ,

Additionally, the proposed change is-consistent with the NRC policy for improving technical specifications (52 Fk 3788) and the proposed change '

is consistent with 10 CFR 50.36.

In view of the preceding, New Hampshire Yankee has determined that the proposed License Amendment Request does not involve any significant-hazards considerations.

VI. Et2E2. sed Schedule for license AmendmenLi;_tyAnce and Effectivenest New llampshire Yankee requests NRC approval and issuance of this License Amendment Request by December 15, 1991. Within 30 days of NRC issuance of the License Amendment, NHY will submit the CORE OPERATING LIMITS REPORT for Seabrook Station Unit 1, Cycle 2 to the NRC and will concurrently implement the Technical Specification changes authorized by the License Amendment. New Hampshire Yankee therefore proposes that the License Amendment become immediately effective upon issuance with implementation required within 30 days of issuance.

The schedule proposed by New llampshire Yankee will eliminate the necessity to submit a license Amendment Request for potential changes to cycle specific parameter limits in Cycle 3 and future operating cycles.
