b. BACKGROUND Beaver Valley Power Station (BVPS) Unit th). 1 and 2 each have two emergency diesel generators. Two diesels are fully dedicated to each plant, with- one diesel assigned to each of the-redundant electrical pruar divisions of each plant. There is no sharing of diesel generators between units. Power from one diesel to one electrical division of each plant is sufficient to provide either for safe shutdown loads or for accident loads. The D/G's at BVPS~

Unit I are manufactured by General Motors Electro-Motive Division and BVPS Unit 2-D/G's are manufactured by Fairbanks Morse Engine Division of Colt Industr2es.

Our present technical specifications require starting the operable diesel _ w ithin 1_ hour and every_8 hours thereafter when specific conditions exist. Generic Letter (GL) f 84-15, " Proposed _

Staff- Actions to Improve and Maintain- Diesel Generator i Reliability," provides guidance for revising stare frequencies for diesel generators under _certain conditions to- improve reliability. This proposed change incorporates NRC guidance intended to improve diesel generator reliability,

i. _ __ _

l C. JUSTIFICATION The ' proposed revisions to LCO. 3.8.1.1 action statements are ,

consistent with-the action statements approved for Virginia, Power Company North _ Anna Unit 1 and 2 and similar to those appr,ved.for-Northea,t Utilities Mi'llstone Unit 2. The proposed revisions are l also_similar to those' contained in_ App 3ndix A of GL 84-15.

. ATTACliMENT B, continued I proposed Technical Specification Change Nos. 200 and 67 Page 3 The following is a discussion on the provision that would be added to not require performance of SR 4.8.1.1.2.a.5 if the D/G has been rendered inoperable due to proplanned maintenance or

, surveillance testing. This provisjon would be added to the proposed Action Statements "b" and "c". The current. wording requires that the alternate train testing be performed, i.e.,

statting of the opposite train D/G, to provide a positive demonstration that a loss of nafety function has not occurred.

There are situations where reduced operability testing on the l remaining diesel can exist when a diesel is made inoperable due i to preventative maintenance or testing. The purpose far testing the remaining dicsol is to assure a common mode failure does not i exist. Since the reason for D/G inoperability is known, i.e.,

preventative maintenance or testing, then a common modo failure on the remaining D/G does not exist. The NRC staff- has ,

recommended, por a memorandum dated February 11, 1991, (Entry -

Into A Technical Specification LCO During Performance of Surveillance Testing) ' that licensees- change their current technical specification wording to eliminate the need for such testing if a D/G is taken out of service for proplanned-preventative ma ntenance or testing. Therefore, the provision that would bot require that performance of SR 4.8.1.1.2.a.5, if the D/G has been rendered inoperable due to preplanned maintenance or surveillance testing, is proposed to be added to Action Statements "b" and "c".

The present Action Statement "a" would be divided into two separate action statements based on GL 84-15. The present requirement to start each D/G within one hour and every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months thereafter, due to a loss of an offsite power source, we believe i is excessive and will lead to accelerated.D/G wear. This action is . intended to verify the availability of a backup power source.

The D/Gs are designed and are intended to be standby power sources. Under the present wording, in just one 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months period'a total of nine D/G tests would be required por D/G. This repetitive type testing introduces accelerated D/G wear and

-provides little additional assurance of D/G availability than what was provided in the previous successful test. A test frequency of one' D/G test in the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of one offsite source being inoperable, unless the D/G has been tested.in the e previous 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , is proposed to minimize repetitive testing.

This test frequency will provide assurance of _ tarting. capability '

and also provide additional ~ time for inspaction and prolube and' other pre-start activities recommended by the manufacturca-to minimize- the- mechanical stress -and- wear on the D/Gs.

Furthermore,- 24 hours . permits sequential testing of the D/G5 rather than the simultaneous testing of both. Repetitive testing increases the likelihood of a D/G failure rather than providing continued assurance of starting capability especially since loss of an offsite _ power source does not directly imply a failure of the D/Gs.

The proposed Action Statement "b" provides the appropriate responses when declaring one D/G inoperable.- The present wording requires that the opposite train be tested within 1-hour and at *

. ATTACHMEllT B, continued proposed Technical Speci12 cation Change lion. 200 and 67 Page 4 least once per 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months thereafter. The reason to perform a diesel test following the loss of one diesel is to ensure that the remaining diesel will be operabic and capable of starting as designed. Specifically, an operability test of the remaining diocol provides assurance that the remaining operable diesel is not subject to the same failure (i.e., common mod 6 failure).

Testing within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months provides timely assurance of diesel operability while providing the additional time for inspection prior to testing As stated in the discussion for the proposed Action Statement "a", repetitive testing every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months following the initial confirmation of diesel operability is unnecessary.

This change to require D/G testing within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months is consistent with GL 84-15. _

The proposed Action Statement "c" provides the appropriate response- to be taken upon declaring one offsite circuit and one diesel generator inoperable. Consistent with the proposed changes to Action Statements "a" and "b", the proposed changes to Action Statement "c" provide adequate assurance of diesel operability by one-time testing while eliminating repetitive testing. The performance of the D/G test within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months provides adequate assurance of the availability of the remaining D/G while eliminating excessive starts and also providing added time for inspection prior to testing. Since the allowable outage period for .this action is 12 hours, follow-up D/G starts are not applicable.

1he proposed Action Statement "d" provides the appropriate responses to be taken upon declaring two offsite power circuite inoperable. The proposed change is consistent with those made for Action Statements "a", "b", and "c". As noted in the discussion for Action Statement "a",_ loss of anLoffsite circuit does not suggest tl.at the diesels have become less reliable than demonstrated by previous surveillance tests. Given the significance of losinc both offsite circuits, one operability test per diesel within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months provides adequate assurance of

-diesel reliability.

The proposed Action Statement- "e" provides the appropriate responses to be- taken upon-declaring both D/Gs inoperable.--The proposed change is the same as existing Action Statement "d".

The only difference in the proposed change is the use of distinct action statements based on the number of D/Gs inoperablo (either one or both).

The addition of the new footnote will ensure that the remaining.

operable. diesel generator -is started regardless of when the inoperable diesel generator'is restored to operable status.1 This action . will verify that a common mode failure does not exist on tne- remaining operable diesel. _ The change to the existing footnotes, by designating _them with_ numbers instead of symbols, along -with the deletion of two footnotes on Page 3/4 8-3 for BVPS Unit fio . 2, is administrative in nature and does not affect plant safety, y

D. SAFETY ANALYSIS The A.C. electrical power sources are designed to provide sufficient capacity, capability, redundancy, and reliability to-ensure tla availability of necessary power to engineered safety features (ESP) systems so that the fuel, reactor coolant system, and containment design limits are not exceeded. The proposed changes to LCO 3.8.1.1 action statements will continue to ensure that the A.C. electrical power sources will perform au designed.

The capacity, capability, and reaundancy of the alectrical power sources is not affected by this proposed change. The specific number of offsite circuits and diesel generators that are required to be operable remains unchanged. The length of time !

and number of components that can be inoperable for continued !

plant operation remains unchanged. The specific parameters, contained in the surveillance requirements, that each component must meet to be determined operable, remains unchanged. The-proposed changes are intended to enhance diesel generator reliability by eliminating excessive testing which can lead to premature diesel failures. When n D/G is made inoperable.due to preplanned maintenance or surveillance tonting, there is not a concern that a common mode failure exists on the remaining D/G.

The reason for D/G inoperability is known. Therefore, requiring the starting of the remaining D/G within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months and at least once ,

per 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months thereafter, provides no additional safety benefits and can lead to premature diesel failures. Also, the present requirement to perform nine D/G starts in a 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months period does ,

not provide any additional safety benefits. This repetitive type testing introducer accelerated D/G wear and provides little additional assurance of D/G availability than what was provided in the previous successful test. A one time start of a D/G, l while~ in an action statement, is sufficient ~to ensure a loss of safety function has not occurred.

Therefore, this change is considered safe based on continued-ability of the A.C. electrical power sources to provide sufficient capacity, capability, redundancy, and reliability to ensure the availability of power to ESF cystems. The proposed changes are. InterAod to enhance D/G reliability by eliminating ,

excessive testing. The overall result of this change is to

enhance the ability of ...C, electrical power sources to perform as originally designed to ensure continued safe plant operation.

E. NO SIGNIFICANT HAZMDS EVALUATION The no significant_ hazard considerations involved with- the oroposed amm.ument have been evaluated, focusing on the three sJandard, set forth in 10 CFR 50.92(c)fas quoted below: )

The Commission. may make a final determination, pursuant to l the procedures-in paragraph 50.91, that a. proposed _ amendment to an operating license for a facility licensed under paragraph 50.21(b) or paragraph 50.22 or for a testing i facility involves no significant hazards' consideration, if

operation of the facility in accordance with the proposed !

amendment would nott (1) Involve a significant increast in the probability or consequences of an accident previously evaluated; or (2) Create the possibility of a new or different-kind of '

accident from any accident previously evaluated; or :

(3) Involve a significant reduction in a margin of safety.

The following evaluation is provided for the no significant hazards consideration standards. .

1. Does the change involve a significant increase in the- '

probability or consequences of an accident previously evaluated?

The probability of occurrence of a previously evaluated accident is not increased because the allowable outage times for the offsite circuits and diesel generators remains unchanged. The consequences of an accident previously evaluated is not increased because reducing the diesel generator test frequency is intended to enhance diesel.

reliability. By eliminating excessive testing,.which can Icad to prenature diesel failures, the diesel generator reliability is increased. This . proposed change.does not affect the availability or reliability of the offsite circuits.

Therefort, this change will not increase the probability or ,

consequences of an accident previously evaluated due to the continued availability and reliability of the A.c.

electrical power-sources.

2. Does the change create the possibility of a new or different kind of accident from any accident previously evaluated?

The proposed changes do not alter the method af operating the plant. The changes do-not introduce any new failure-modes and are intended. to increase the diesel generator reliability. The revision to the various action statements provido assurance that the diesel generators will be able to power their respective safety . systems if required. The proposed changes do not impact the performance of any safety sv3Lem.

Therefore, this. proposed. change does- not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. Does- the change involve a significant-reduction in a margin of safety?

The margin of safety is not reduced because the A.C.

and containment design limits are not exceeded. Tne ulimination of excessive testing on the diesel generators is intended to increase reliability by reducing. wear on the diesel. The increased reliability of the diescis adds.to the ability of A.C. electrical power source to provide power to ESF systems.

Therefore, this proposed change does not involve a significant reduction in a margin of safety.
