APPLICABILITY BASES The same principle applies with regard to the allowable outage time limits of the ACTION requirements, if compliance with the ACTION requirements for one specification results in entry into a MODE or condition of operation for another specification in which the requirements of the Limiting Condition for Operation are not met.

If the new specification becomes applicable in less time than specified, the difference may be added to the allowable outage time limits of the second specification.

However, the allowable outage time limits of ACTION rhquirements for a higher MODE of operation may not be used to extend the allowable outage time that is applicable when a Limiting Condition for Operation is not met in a lower MODE of ooeration.

The shutdown requirements of Specification 3.0.3 do not apply in MODES 5

and 6, because the ACTION requirements of individual specifications define the remedial measures to be taken.

3.0.4 This specification establishes limitations on MODE changes when a Limiting Condition for Operation is not met.

It precludes placing the facility in a higher MODE of operation when the requirements for a Limiting Condition for Operation are not met and continued noncompliance to these conditions would result in a shutdown to comply with the ACTION requirements if a change in MODES were permitted.

The purpose of this specification is to ensure that facility operation is not initiated or that higher MODES of operation are not entered when corrective action is being taken to obtain compliance with a specification by restoring equipment to OPERABLE status or parameters to specified limits.

Compliance with ACTION requirements that permit continued operation of the facility for an unlimited period of time provides an accept-able level of safety for continued operation without regard to the status of the plant before or after a

MODE change.

Therefore, in this case, entry into an OPERATIONAL MODE or other specified condition may be made in accordance with the provisions of the ACTION requirements.

The provisions of this specification should not, however, be interpreted as endorsing the failure to exercise good practice in restoring systems or components to OPERABLE status before plant startup.

When a shutdown is required to comply with the ACTION requirements, the provisions of Specification 3.0.4 do not apply because they would delay placing the facility in a lower !10DE of operation.

Exceptions to this provision have been provided.or a limited number of specifications when startup with inoperable equipment would not affect plant sa ety.

These exceptions are stated in the ACTION statements of the appro-priate specifications.

3/4.8 ELECTRICAL POWER SYSTEMS BASES The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the safety related equipment required for 1) the safe shutdown of the facility and 2) the mitigation and control of accident conditions within the faci,lity.

The minimum specified indepen-dent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General Design Criteria 17 qf Appendix "A" to 10 CFR 50.

The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility ooeration commensurate with the level of degradation.

The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least one of each of the onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite power and single failure of the other onsite A.C. source.

The OPERABILITY of the minimum specified A.C. and D.C. power sou. ces and associated distribution systems during shutdown and refueling ensures that 1) the facility can be maintained in the shutdown or refueling condition for extended time periods and 2) sufficient instrumentation and control capability is available for monitoring and maintaining the facility status.

INSERT ¹ The Surveillance Requirements for demonstrating the OPERABILITYof the diesel generators are in accordance with the recommendations of Regulatory Guide 1.108, "Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977, Regulatory Guide 1.137, "Fuel 011 Systems for Standby Diesel Generators," Revision 1, October 1979, Generic Letter 84-15, "Proposed StaKActions to Improve and Maintain Diesel Generator Reliability," dated July 2, 1984, and NRC staK positions reflected in Amendment No. 48 to Facility Operating License NPF-7 for North Anna Unit 2, dated April25, 1985.

SAFETY ANALYSIS 4

On July 2, 1984, the NRC issued Generic Letter 84-15, "Proposed Stafi'Actions to Improve and Maintain Diesel Generator Reliability." This generic letter presented the NRC's conclusion that the frequency of diesel generator cold fast start surveillance tests from ambient conditions should be reduced to prevent premature diesel engine degradatlon, and encouraged licensees to accomplish a reduction in the number of cold fast start surveillance tests from ambient conditions.

On April25, 1985, the NRC issued Amendment No. 48 to Facility Operating License No. NPF-7 for North Anna Unit 2. The amendment revised the emergency diesel generator Technical Speclfications by reducing the required testing. The changes addressed both routine surveillance and special tests, upgraded the parameters for each test and reduced the number of tests.

On October 19, 1987, FPL submitted a request to amend the St. Lucle Unit 2 Technical Specificatlons to be similar to the North Anna Unit 2, Amendment No. 48 Technical Specificatlons.

The NRC issued Amendment No. 39 to the St. Lucle Unit 2 Operating License on February 10, 1989, incorporating these proposed changes.

FPL now proposes to revise the St.

Lucie Unit 1 Technical Specifications to be similar to the St. Lucie Unit 2 Electrical Power Systems, A.C. Sources Technical Specifications.

I I N Emergency diesel generators (EDGs) are credited ln updated Final Safety Analysis Report (UFSAR) Chapter 15 accident analyses that assume a loss of ofislte power. The analyses include virtually every type of accident, from reactivity initiated accidents (e.g., CEA Drop and CEA E]ection) to primaxy and secondary system pipe breaks (e.g., Steam Line Break and Loss of Coolant Accident). When evaluating these accidents, it is assumed that one EDG fails to start and/or load; hence, each EDG must be capable ofpowering the Engineered Safety Features (ESF) that are necessary to mitigate the consequences ofthe accident.

The St. Lucie Unit 1 diesel engines were manufactured by General Motors EMD, model number 645-E4.

Each diesel engine set consists of one 12 cylinder and one 16 cylinder engine mounted ln tandem, with a generator mounted in the middle.

Pre-operational testing ofthe diesel generators was completed ln early 1976.

The peak accident load (l.e., the power that must be available during the Qrst two hours ofthe design basis accident) which each Unit 1 EDG must be able to carry is approximately 3463 kW.

The Unit 1 EDGs have design load ratings of3960 kW and 3500 kWfor 30 minutes and continuous operation, respectively. In order to ensure that these EDGs can perform as they were designed, lt is important that they be tested on a routine basis.

However, when the testing becomes excessive (as much as 3 times a day for some ACI'IONStatements) the tests themselves can lead to EDG degradation and, subsequently, reduce reliabilityand availability. The proposed change to the Technical Specifications provide for an overall reduction in diesel generator testing that is consistent with the guidelines provided by NRC Generic Letter 84-15

and the EDG Technical Specfflcatfon changes approved by the NRC for St. Lucie Unit 2. The proposed change willenhance the overall relfabflfty and avaQability ofthe St. Lucfe Unit 1 EDGs.

The intent of the Electrical Power Systems, A.C. Sources Technical Specifications and other related Technical Specfflcatfons fs to ensure there is sufllcient power avaQable to supply the safety-related equipment required for safe shutdown of the plant and mitfgatfon and control of accident conditions. The redundancy ofthe power sources required (2 onsfte sources and 2 offsfte sources) ensures that even during an accident with a coincident loss of offsfte power and a single faflure of one onsfte A.C. power source, there fs sufficien power avaQable to supply all required safety systems. The LimitingCondition for Operation (LCO) ACTION Statements and/or LCOs restrtct operation of the plant ln a manner consistent with the degree of inoperability. For example, when one EDG is inoperable, the ACTIONStatement or LCOs require verfflcatfon that all other A.C. sources are operable and that all required systems, subsystems, trains and components that depend on the remaining EDG are also operable.

This provides assurance that a loss of offsfte power willnot result in a complete loss of safety function ofcritical systems during the time one EDG fs inoperable.

The proposed changes to the ACTION Statements and LCOs are either administrative (such as dividing current ACTION Statement "a" into separate ACTIONStatements "a" and "b") or they implement the reduced testing requirements recommended by NRC Generic Letter 84-15. Additional changes allow for the deletfon ofTechnical Specfflcatlon 3.0.5, and integration into the body ofthe Technical Specifications, as well as permitting Unit 1 to make administrative use of a Unit 2 startup transformer.

in The existing operability requirements and applicable modes have not been amended.

All ACTIONstatements have been rewritten to incorporate the recommendations of Generic Letter 84-15 and the changes made to the St. Lucie Unit 2 speciQcations.

The format of Generic Letter 84-15 divides the action statements into Qve categories: one oQsite circuit.inoperable, one diesel generator inoperable, one oQsite circuit and one diesel generator inoperable, two oQsite circuits inoperable, and two diesel generators inoperable.

The new Action Statements proposed in this amendment request followthe same format. The intent of these changes is to increase the reliabilityofthe diesel generators by reducing the frequency offast, cold starts from ambient conditions.

Proposed ACTIONStatement 3.8.1.l.a addresses the case in which one oQsite circuit is inoperable; ACTION Statement 3.8.1.1.b addresses the case in which one diesel generator is inoperable.

Both of these cases are addressed in the existing ACTIONStatement 3.8.l.l.a, which is to be deleted.

Proposed ACTIONStatement 3.8.l.l.a retains the same surveillance requirement for the operable oQsfte circuit and also retains the requirement to return the inoperable oQsite circuit to operable status with 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months .

The proposed change also reduces the number of cold, fast starts ofthe diesel generators by requiring the engines be tested within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ifeach diesel has not been successi'ully tested within the past 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . The current testing frequency is within one hour after entering the ACTIONStatement, and then once every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months thereafter.

Testing ofthe engines willbe performed in accordance with the guidance provided in Generic Letter 84-15, which allows the prelubrication of all moving parts and warmup prior to starting. The reduction of the periodic testing and the 'slow'tart of the diesel generator during the period oftime when an offsite circuit is not operable (up to 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months ) is

]ustified on the basis that the operability ofboth diesel generators is assured because they have been tested during the previous 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , and, ifnot, they willbe tested to demonstrate operability within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of declaring the oQ'site circuits inoperable.

The requirements ofproposed ACTIONStatement 3.8.1.l.b allow the OPERABLE diesel generator to be teated within24 hours ofdetermining that the other engine is inoperable. This test is to be performed regardless ofwhen the inoperable diesel is restored to service, and is to'e performed in accordance with manufacturer recommendations concerning engine warmup and prelubrication. The net effect of the change is to reduce the operable diesel generator testing frequency and type ofstart such that a high degree of assurance the availability of A.C.

power remains because two oAsfte circuits are operable and one diesel generator is operable.

Proposed ACTION Statement 3.8.1.l.c addresses the inoperabliiity of one oQsite circuit and one diesel generator.

The existing ACTIONStatement 3.8.1.1.b addresses this condition and is to be deleted.

The intent ofthis change is to reduce the frequency ofthe operable diesel generator starts as well as the number offast, cold sos.

Should two ofthe four available AC sources be inoperable, starting of the remaining operable diesel generator is to be performed within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months ofentering the ACTION Statement, which is commensurate with two power sources being inoperable.

An additional requirement is being added to ACTIONStatements 3.8.1.l.b and 3.8.l.l.c to verify the operability ofall required systems, subsystems, trains, components and devices that depend on the remaining operable diesel generator as a source of emergency power must also be

operable.

The new requirement is intended to replace the existing L.C.O. 3.0.5, making the Unit 1 and Unit 2 Technical Specifications consistent with respect to AC power sources.

L.C.O. 3.0.5 prohibits operation when one division of equipment is inoperable because its normal or emergency power source is inoperable and a system, subsystem, train, component or device in another division is inoperable for another reason.

The proposed new ACTIONStatement addresses this same requirement, and incorporates a 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months shutdown requirement if operability of redundant systems cannot be verified.

Proposed ACTION-Statements 3.8.l.l.d and 3.8.l.l.e replace the existing ACTIONStatements 3.8.1.1.d and e. The revised ACTIONStatements incorporate the recommendations of Generic Letter 84-15 and the changes made to the Unit 2 Technical Specifications.

Anew ACTIONStatement, ACTION3.8.1.1.f, has been added. allowing Unit 1 to make administrative use of a Unit 2 startup transformer when one Unit 1 startup transformer is not operable. This design feature ofthe St. Lucie Plant was reviewed during the licensing of St.

Lucie Unit 2 in NUREG-0843, "Safety Evaluation Report (SER) Related to the Operation ofSt.

Lucie Plant, Unit 2," dated October, 1981. In SER Section 8.2.1, the staff wrote, Each startup transformer is sMed with sufficient capacity to accommodate the auxQiary loads ofthe unit under any operating and postulated design basis accident load conditions.

Each set ofstartup transformers (1A-1B for Unit 1 and 2A-2B for Unit 2) is provided with a manual switching arrangement which permits paralleling 4.16 kQovolt power to St. Lucie Units 1 and 2 under administrative control. In the event one of the four startup transformers has to be removed from service for repair, the 4.16 ldlovolt power to both St. Lucie Units 1 and 2 is paralleled to facfiitate continued operation ofboth units.

Our evaluation of the proposed sharing of a startup transformer to facilitate continued operation when one startup transformer is out of service indicated that under certain modes ofoperation (i.e., in the event ofan accident in one unit, with simultaneous orderly shutdown ofthe other unit) the shared startup transformer could be overloaded.

Therefore, plant-specific Technical Specifications for St. Lucie Unit 2 willbe required to address limiting conditions for operation with one startup transformer and/or tie to the oQ'site power network... [in]operable...

... We find the capacity and capabQity ofthe oQsite power system and its circuit ties to the onsite distribution system to be in accordance with the requirements of General Design Criteria 17 and 5 (with respect to multi-unit sharing) and therefore acceptable.

As this design feature ofthe St. Lucie units has already been evaluated and found to be acceptable, the addition ofACTION Statement fis considered to be administrative in nature.

Technical Specifications, and Generic Letter 84-15.

Surveillance Requirement 4.8.1.1.2.a has been rewritten to incorporate testing requirements in the Combustion Engineering Standard Technical Speciflcations, the St. Lucie Unit 2 Technical Speciflcations and the recommendations of Generic Letter 84-15 relative to diesel generator starting and loading practices.

Scheduling ofthe tests is also being amended to require that test frequency be dictated by the number offailures during a specifled testing period. Anew Table 4.8-1 has been added in accordance with Generic Letter 84-15 and St. Lucie Unit 2 Technical Speciflcations.

Diesel testing requirements are being changed in two ways. First, the Unit 1 diesel generators willbe required to start from ambient conditions and reach rated speed and voltage within 10 seconds once every 184 days. Allother starts of the engine may be preceded by an engine prelubrication and warmup period to ensure that mechanical stress and wear are mMmized.

Secondly, the existing loading speciflcation is being amended to include loading the diesel generator to 3500 kWwithin 60 seconds, followed by a minimum 60 minute run while operating within a load band of3300 to 3500 kW. Loading the engines in the 60 second time period is to be performed at least once per 184 days; the load band has been provided to avoid routine overloading of the engines.

These new requirements are in accordance with Generic Letter 84-15 recommendations and the Unit 2 Technical Speciflcations.

The lower load band limits were calculated for St. Lucie Unit 1 in the same manner as the load limits were calculated for St. Lucie Unit 2. Error in the kWmeasurement circuit (instrumentation and calibration error) and operator misreading (parallax) error of the kW meter result in a total possible loop error ofk3.65%; over the span of a 5500 kW meter, a MOO kW inaccuracy is possible.

As on Unit 2, the lower end ofthe proposed Unit 1 load band (3300 kW) is less than the peak accident load (3463 kW). However, as peak accident load occurs only over a short period of time, the determination that the Unit 2 difl'erence was not signiflcant is also applicable to Unit l.

Surveillance Requirements 4.8.1.1.2.b, c and d are discussed in the section pertaining to fuel oil surveillance requirements.

Surveillance Requirement 4.8.1.l.e has been rewritten to incorporate the recommendations of Generic Letter 84-15, the Combustion Engineering Standard Technical Speciflcations and the changes made to the Unit 2 Technical Speciflcations as appropriate to the Unit 1 design bases.

The existing Unit 1 eighteen month surveillance testing includes the following requirements and tests:

1.

inspection in accordance with manufacturer's recommendations 2.

verifying the diesel generators'apability to reJect a load of 2600 hp without tripping 3.

simulation of a loss of offsfte power in conJunction with a safety inJection actuation signal, with subsequent verification of the following:

a. de-energization ofand load shedding from the emergency busses

b. auto-start of the diesel generators from ambient condition, followed by the energizing ofthe emergency busses with permanently connected loads and the energizing ofthe auto-connected loads through the load sequencing system

c. the diesel generators'apability to operate for h5 minutes while loaded with the emergency loads

d. all diesel generator trips except engine overspeed and generator difI'erential are automatically bypassed upon receipt of a safety inJection actuation signal 4.

veriflcation ofthe engines'bility to operate for 060 minutes while loaded to 23500 kW 5.

verification of the, operability of the load sequence timers.

The proposed surveillance requirements have been amended to reflect those performed for St.

Lucie Unit 2 (with changes made to reflect the Unit 1 design, as appropriate).

Alldiesel engine starts for 18 month testing are to be performed at ambient conditions, without any prior

warmup period for either engine.

Allowance has been made for engine prelubrication, which is in keeping with the intent of Generic Letter 84-15.

The new SurveQlance Requirements have been added which address ten year testing.

Surveillance Requirement 4.8.1:1.2.f requires the diesel generators be tested at least once per ten years, or after implementation of any modQ1cations which could acct diesel generator independence, whQe the plant is shutdown.

Engine starts for this test are to be performed at ambient conditions, but an allowance is made for engine prelubrication prior to testing, in accordance with Generic Letter 84-15. The intent ofthis change is to make the Unit 1 Technical SpeciQcations consistent with St. Lucie Unit 2 Technical SpeciQcations and the CE Standard Technical Specifications concerning emergency power sources.

The second ten year test proposed is a pressure test ofthe diesel fuel oQ system designed to meet USAS B31.7 Class 3 requirements.

The intent ofthis change is to make the Unit 1 Technical Spec1Qcations consistent with St. Lucie Unit 2 Technical SpecfQcations and the CE Standard Technical Specifications.

Arequirement for the cleaning ofthe diesel fuel oQ storage tanks is also proposed.

Cleaning of the tanks is to be performed using an appropriate cleaning compound once ever ten years.

The existing SurveQlance Requirement 4.8.1.1.3 is being replaced by a new reporting requirement; proposed new SurveQlance Requirement 4.8.1.1.4 wQ1 encompass the requirements of the existing 4.8.1.1.3.

Reporting of diesel generator failures wQ1 be required in accordance with Regulator Position C.3.b ofRegulatory Guide 1.108, Revision 1, August 1977.

The intent ofthis change is to make the Unit 1 Technical SpecQlcations consistent with St.

Lucie Unit 2 Technical Specifications and the CE Standard Technical SpeclQcations.

urvHI n R uirmn frFu 1

Q The proposed fuel oQ surveQlances for the Unit 1 Technical specifications are identical to those currently in use at St. Lucfe Unit 2. SurveQlance Requirement 4.8.1.1.2.b is being replaced by proposed SurveQlance Requirements 4.8.1.1.2.b, c and d. Aminor change has been made to the Unit 1 Specifications which willallow for the removal of accumulated water from the diesel oQ storage tanks once every 94 days. The existing Unit 2 specification requires that this surveQlance be performed once every 31 days; plant experience to date has indicated that the amount ofwater being taken from the tanks is minimal, and does not appear tojustifythe amount offuel oQ waste which is generated.

The intent ofthe proposed EDG fuel oQ surveQlance requirements is as follows:

New fuel is to be tested prior to addition to the storage tanks to detect contamination which could occur after leaving the reQnery.

Fuel leaving the refinery is generally good quality and must meet ASTM standards; however, as a second check, the proposed Technical Specification would require verifying ASTM D975-81 is met for new fuel.

2.

Fuels in storage should be tested periodically to detect degradation.

Only those parameters which can change during storage need to be tested.

Periodic testing for particulate formed in storage should concentrate on ag~u particulate contamination.

Testing in accordance with ASTM D2276-83, Method A or Annex A, meets this criterion. This test wQl be performed every 31 days for fuel in storage.

Since formation ofparticulate during storage at ambient temperatures is a relatively slow process, the 31-day test frequency wQ1 ensure early detection of particulate. This test need not be performed on new fuel receipts because the Clear and Bright test (ASTM D4176-82) detects particulate in new fuel. The ASM D2276-83 test is a relatively simple test which can be performed onsite.

The proposed fuel oQ Surveillance Requirements have been reviewed by the staff for St. Lucie Unit 2.

The staff has determined that this program is a more conservative approach to fuel oQ, surveillance and should therefore increase diesel generator avafiabQity. The program has been determined by the staff to be independent ofplant-specific design and to be generically applicable.

DETERMINATIONOF NO SIGNIFICANTHAZARDS CONSIDERATION The standards used to arrive at a determination that a request for amendment involves no slgnfQcant hazards consideration are included in the Commission's regulations, 10 CFR 50.92, which states that no significant hazards considerations are involved ffthe operation of the facility in accordance with the proposed amendment would not (1) involve a sfgnfQcant increase ln the probability or consequences of an accident previously evaluated; or (2) create the possiblllty of a new or dfQerent kind of accident from any accident previously evaluated or (3) involve a sfgnfQcant reduction fn a margin of safety.

Each standard is discussed as follows:

(1)

Operation of the facilityin accordance ofwith the proposed amendment would not involve a sfgnfQcant increase fn the probability or consequences of an accident previously evaluated.

The probability of occurrence of an accident previously evaluated in the FSAR has not been affected since the emergency diesel generators do not affect the probabilities of occurrence of accidents.

The consequences of an accident previously evaluated in the FSAR have not been increased.

Reducing the test frequency and modifying the starting requirements to be consistent with the diesel manufacturer's recommendatfons are intended to enhance diesel relfabfiftyby minimizing severe test conditions which can lead to premature failures.

The probability of a malfunction of equipment important to safety previously evaluated in the FSAR has been reduced since the severe test requirements have been reduced which willresult fn increased diesel engine reliability.

The consequences of a malfunction of equipment important to safety previously evaluated fn the FSAR have not changed since the new surveillance requirements will not affect the operation or operability of the dfesels or any other safety-related equipment.

The proposed amendment willnot involve a slgnfQcant increase in the probability or consequences ofan accident previously evaluated in that the proposed change involves replacing fuel oil tests currently required by Technical SpeciQcations with Technical SpeciQcation Surveillance Requirements whfch are more effective in detecting unsatisfactory fuel oil and are simpler to perform.

The deletion of LimitingCondition for Operation (LCO) 3.0.5 willnot involve a slgnfQcant increase in the probability or consequences of an accident previously evaluated.

This LCO currently delineates what additional conditions must be satisQed to permit operation to continue, consistent with the ACTIONstatements for power sources, when a normal or emergency power source is not OPERABLE. It speclQcally prohibits operation when one division fs inoperable because its normal or emergency power source is inoperable and a system, subsystem, train, component or device in another division fs inoperable for another reason.

The Technfcal Speclficatfons have been revised to incorporate this requirement in the ACTION statements for normal or emergency power source fnoperabilities for MODES 1 through 4. In MODES 5 or 6 the ACTIONstatement for SpeclQcation 3.0.5 does not apply, and thus the individual ACTION statements for each applicable Limiting

Condition for Operation in these MODES must be adhered to. Exceptions to requirement are incorporated in specific individual Technical Specifications.

Since this change is administrative in nature and no OPERABILITFrequirements have been deleted, no significant increase in the probabQity or consequences of an accident previously evaluated is involved.

The addition ofnew ACTIONStatement fto LCO 3.8.1.1, pertaining to the administrative avaQabQity of a Unit 2 startup transformer for use by Unit l,wQI not involve a signQIcant increase in the probabQity of an accident previously evaluated since the startup transformers do not affect probabQity calculations or determinations.

The addition ofnew ACTIONStatement fto LCO 3.8.1.1, pertaining to the administrative avaQabQity of a Unit 2 startup transformer for use by Unit 1, willnot affect the consequences ofan accident previously evaluated in that the proposed addition has been determined to meet the requirements of General Design Criteria 17 and 5, with respect to multi-unit sharing. This change incorporates a design feature already evaluated in during the construction and licensing of St. Lucie Unit 2.

(2)

Operation ofthe facQity in accordance with the proposed amendment would not create the possibQfty of a new or diQ'erent kind of accident from any accident previously evaluated.

The possibQity of a new or diQ'erent kind of accident other than that analyzed in the FSAR has not been created since the change affects the starting and loading practices during testing only and has no impact on actual accident analyses. The possibQity of a malfunction of equipment important to safety of a different type than any analyzed in the FSAR has not been increased.

In fact, the probabQity of equipment malfunction has been reduced as the result ofthe improved testing conditions and frequency of testing as discussed in Generic Letter 84-15.

The proposed amendments would replace fuel oQ tests currently required by the Technical Specifications with different tests which are more effective for ensuring quality-fuel oQ. These changes are:

(a)

The proposed testing requirements would improve the capability to detect delivery of diesel fuel contaminated with gasoline orjet fuel (JP-4) by adding a test for Qash point.

(b)

The proposed Clear and Bright test is more sensitive for detecting water and sediment than the test which is currently required.

(c)

The accelerated oxidation stability test which predicts the tendency of the fuel to form particulates during storage would be replaced by a different test performed more frequently which actually measures particulates in the fuel.

(d)

Because proposed tests for incoming fuel shipments willensure its quality, periodic testing would only be required for the parameters which can change during storage.

Thus, certain test requirements would be deleted.

(e)

Because ofthe high degree ofprotection obtained by the tests for incoming fuel prior to addition to the storage tanks, the proposed relaxation ofthe time limit for complete fuel specification testing from 14 days to 31 days is insignificant.

(I)

Since comparative gravity, as proposed, can detect contamination by)et fuel (Jet A) and other types ofcontamination are detected by tests other than viscosity,

viscosity testing is not required ffgravity is determined using this method.

(g)

Under the proposed amendments, analysis for sulfur using any one ofthe three generally accepted methods would be allowed.

(h)

Administrative changes would be made to reference up-to-date industry standards.

(1)

The requirement to periodically remove accumulated water from the day tanks would be extended to include the storage tanks.

The addition ofACTION Statement fdoes not create the possibility of a new or different kind of accident from any previously evaluated in that the inoperability of the offsite power source fs assumed fn the accident analyses on record.

(3)

Use of the modlQed speciQcation would not involve a sfgnfQcant reduction fn a margin of safety.

The margin of safety as defined fn the basis for any Technical SpeciQcatfon is not reduced by the proposed changes.

The changes in the testing requh'ements do not affect the capability of the dfesels to perform their function. The purpose ofthe change fs to increase the diesel engine reliability.

The deletion of LCO 3.0.5 does not involve a stgnfQcant reduction in a margin of safety since the requirements for normal or emergency power source OPERABILITYhave been moved from LCO 3.0.5 to the ACTIONstatements forA.C. Power Systems fn MODES 1 through 4. Exceptions to the Operability requirements fn MODES 5 and 6 currently permitted by LCO 3.0.5 have been moved to the individual speclQcations.

The addition ofACTIONStatement fto the Unit 1 Technical Specifications does not involve a sfgnfQcant reduction in any margin of safety fn that this change is considered to be administrative ln nature.

The desfgn of the offslte power network was evaluated during the construction and licensing ofSt. Lucle Unit 2, and was found to be in accordance with the requirements ofGeneral Design Criteria 5 and 17 with respect to multi-unitsharing. As stated in the bases for the St. Lucle Unit 2 Technical SpecfQcatfons,

" the ACTION requirements specfQed for the levels of degradation ofthe power sources provide restriction upon continued facilityoperation commensurate with the level of degradation.

The OPERABILITY ofthe power sources are consistent with the initialcondition assumptions ofthe safety analyses and are based upon maintaining at least one redundant set of onslte A.C. and D.C. power sources and associate distribution systems OPERABLE during accident conditions coincident with an assumed loss of offslte power and single failure of the other onslte A.C. source."

Based upon the above, we have determined that the amendment request does not (1) involve a sfgnfQcant increase fn the probability or consequences of an accident previously evaluated, (2) create the probability of a new or different accident from any accident previously evaluated, or (3) involve a slgniQcant reduction ln a margin of safety, and therefore does not involve a sfgniQcant hazards consideration.
