The proposed amendments, in part, would delete several Technical Specifications (TSs) which determine the operability of the emergency load !

sequencing and timing circuits and provide detection of diesel generator interdependence in TSs 4.8.1.1.2.c.2 (Unit 2), 4.8.1.1.2.b.6 (Unit 1), and

$0 $0$ $ 00 5 qeme e see

4.8.1.1.2.d (Unit 2), respectively. The Commission has determined that inclusion of these TSs is necessary to provide assurance of the availability of the safety ,

1 functions provided by the diesel generators and, therefore, shall not be, deleted.

Another proposed change to the TSs denied was the increase in time from 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months to 168 hours0.00194 days 0.0467 hours 2.777778e-4 weeks 6.3924e-5 months for restoration of an inoperable diesel generator.

I licensee submitted a Technical Specification change request attempting to more closely reflect the Standard Technical Specifications ,(STS) enclosed in Generic Letter 84-15. Additional information and improved TS's are indluded in letters dated June 25, and September 28, 1987. A letter dated November 25, 1987 requests TS changes to two specific portions of the priginal submittal concerning diesel generator fuel oil surveillance testing and the ten year diesel generator fuel oil storage tank cleaning.

2-2.1.1: Introduction . .

By letter dated' June 25, 1987, the licensee' proposed changes to section 3/4 8.1 of the TSs concerning surveillance requirements for the diesel generator fuel oil system. Additional information is provided by letters dated September 28, and -

November 9, 1987. The TS change request dated June 25, 1987 was superseded by a TS change request dated November 25, 1987. The staff notes that the pt,oposed changesi deviate from the guidelines in the Standard Technical Specifications

(STS) for Westinghouse plants. . -In addition, the proposed TS changes provide for uniformity in the TSs for both Units 1 & 2.

2.1.2 Evaluation.

! The primary deviation of the licensee's proposed TS from the STS is the deletion of the requirements for testing of stored fuel oil particulate concentration in accordance with American Society for Testing Materials (ASTM) D2274-70 every 92

' days._ In lieu of the above, the proposed TS requires testing of stored fuel oil for particulate concentrations every 31 days in accordance with ASTM D2276-83.

The propo:ed test more closely confirms the actual condition of the fuel oil ;

, that will be pumped to the diesel generators in terms of particulate matter which could impair diesel generator operation or result in diesel generator

. uhavailabilify. The current STS surveillance requirements (ASTM D2274-70) are orientated to predicting the tendency of fuel oil to oxidize and form ,

particulate during long term storage rather than determining the particulate

' concentration that may already exist. The staff finds that the more frequent.

testing for actual particulate in the stored fuel oil will provide'better .

indications of fuel conditions as well as identifying the tendency for formation of particulate under site storage conditions. The proposed tests would, -

therefore, be'more conservative in establishing the adequacy of. stored fuel oil than the present'STS guidelines.

Other proposed changes include-(a) replacing the " water sediment" test by ,

centrifuge on new fuel oil per ASTM D1796-with the " clear and bright" test per ASTM D4176-82, (b) use of optional methods of verifying fuel gravity by. testing and comparing with the suppliers certification, (c) allowing sulfur a.nalysis to

!be performed in accordance with ASTM D2262, and-(d) extending the time limit for obtaining ASTM D975 test results on new fuel from 14 days to 31 days. During the course of reviewing the McGuire TS changes, the staff reviewed the " clear and bright" test (ASTM 4176-82) including a demonstration of the test principles.

at the Naval Fuel Laboratory, Norfolk, Vi'rginia. Based on the above review, the ,, , , ,

staff finds the " clear and bright" test to be more sensitive in determining them <

presence of water and sediment in fuel oil than the " water and sediment" test by centrifuge (ASTM D1796).

The use of optional methods of verifying new fuel gravity prior to storing by

-testing and comparing with the supplier s certification is proposed by the

licensee as a means of simplifying new fuel acceptance procedures. The justification.for this change is that any contamination of fuel oil during._ .

transportation would be indicated by changes in flash point, gravity, viscosity, or appearance. Incorrect flash point would be detected by testing as discussed '

further.below. Any contamination which could alter the fuel oil appearance would be detected by the " clear:and bright" test discussed previously. With tests for_ flash point and appearance as additional indicators, a verification

of fuel oil gravity by testing and comparing to the supplier's certification .

will. provide the necessary assurance that the new fuel is within specification limits. The staff finds'the verification of fuel oil gravity by optional methods to be satisfactory. ~

Current ASTM D975 guidelines for testing new fuel oil sulfur content indicate that the testing is to be performed in accordance with ASTM D129. ASTM D396,

" Specification for Fuel Oil," however, allows the use of ASTM D2262 test methods for sulfur determination in No. 2 grade fuel oil. The staff recognizes both of the above fuel oil specifications and believes that obtaining test results by ASTM D2262 will be equivalent to results obtained by use of ASTM D129.

Therefore, the staff finds the proposed alternate method of determining sulfur content to be satisfactory, The current STS guidelines indicate that new fuel oil is to be tested for conformance to the limits of the respective fuel oil properties listed in. Tabla 1 of ASTM D975, and the test results are to be available within 14 days, '

following fuel oil delivery. Under the licensee's proposed surveillance program, the most impor,t. ant fuel oil properties, with regard to immediate diesel engine operability, (flash point, viscosity or gravity, water, and sediment) are checked for, ASTM D975 limits immediately prior to accepting the new fuel oil.

The remaining fuel oil properties may affect diesel generator performance'only on a-long term basis. Thus, the staff finds that the licensee's proposal to extend the time for obtaining test results for the remaining fuel oil properties from 14-days to 31 days would not adversely affect diesel gene'rator operability.

The proposed changes to the TSs include deleting the requirements for testing i of stored fuel oil in accordance with ASTM D975 requirements on a 92 day basis. l The rationale for this deletion is that the main fuel oil properties which can affect diesel generator performance (flash point, cetane number, viscosity, cloud point) and are included in ASTM D975 do not change during storage.

- If. 1 these properties are within specification when the fuel oil is placed in storage, they will remain within specification unless other non-specific petroleum products are added to the storage tanks. The addition of non-specification petroleum products is precluded by the licensee's proposed new fuel surveillance program as described above. Over prolonged periods stored fuel can oxidize and

. form particulate which, in significant enough concentrations, could impair diesel generator performance. In addition, bacteria growth can occur.

Particulate concentrations will be monitored every 31 days as discussed previously. Bacteria growth will be prevented by periodic removal of water frorh - ~~

storage tanks. Because fuel oil properties will not change significantly in _

' storage and fuel oil conditions which could affect diesel generator operation _

wil1~.be closely monitored (on a 31 day basis), the staff finds that further testing of stored fuel in accordance with ASTM 0975 every 92 days will not provide measurable improvement in diesel generator reliability. Therefore, such. testing can be deleted.

The licensee has also proposed two additions to the fuel oil surveillance TSs.

These' include (a) testing new fuel for flash point before acceptance, and (b) '

testing for and draining water from the fuel oil storage tanks every 31 days.

The flash point test provides an additional indication that new fuel oil is within specification limits; thereby,' reducing the possibility of adding " bad fuel" to the fuel oil already in storage. The requirement to drain accumulated

water from the storage tanks every 31 days will be of considerable value in ,

reducing the-possibility of bacteria contamination of the stored fuel, minimizing the formation of corrosion products on the bottom of the storage tank, and preventing water from contaminating the fuel oil transfer system and the diesel generator fuel system. Both of the above additions represent a more conservative approach to maintaining quality diesel fuel and diesel generator

-reliability than current staff guidelines.

2.1.3 Conclusion Based on the above, the staff concludes that the surveillance requirements for ensuring diesel oil adequacy, TS section 3/4 8.1, as proposed by the licensee are more conservative than the guidance in the Standard Technical Specifications.

This conservatism coupled with the simplified testing approach for fuel oil will provide immediate assurance of fuel oil. quality on delivery and maintenance of fuel oil quality during storage. This should increase diesel generator reliability. Therefore, the licensee's proposed TS changes for diesel fuel oil .

surveillance are acceptable.

2.2 Diesel Generator Fuel Oil Storage Tank Surveillance Testina 2 2.1 Intro 8uction In a letter dated September 28, 1987, the licensee revised the original diesel generator fuel oil surveillance test requirement to reflect more closely to similarly approved TSs. Groundwork for a proposed Diesel Generator Fuel Oil Storage Tank Surveillance Test was laid. Initially, problems such as development of procedures and clean tank criterion were identified. Subsequent letters dated November 25, 1987 and January 24, 1989 provided some additional information. In a letter dated March 23, 1989, the licensee addressed all the remaining concerns of the NRC staff.

2.2.2 Evaluation '

Due to the unique design of the licensee's diesel fuel system, periodic

-surveillance testing requiring draining of the storage tanks would force the licensee to shut down both Units 1 and 2. The licensee's letter dated March 23, 1989, proposed an alternative method of ensuring adequate surveillance testing of the diesel fuel oil storage tanks.

Section 4.8.1.1.2.f of the proposed TF requires that on a 10 year basis the licensee perform the following steps. ~ ~

Section 4.8.1.1.2.f.1 of the proposed TS requires that the licensee either (1) drain each storage tank, remove accumulated sediment, and clean the tank, or (2) agitate the fuel oil in the tank while pumping the oil from the bottom of

~ the tank through a 5 micron filter and back into the tank. Additionally,.the tanks will be sampled three consecutive times and analyzed according to ASTM D2276-83. If any of the three samples contain more than 10mg/ liter of '

, contaminate, the agitation, filtration, and sample process must be repeated.

If after three consecutive attempts, the sample still fails the contaminate test, the licensee must drain and clean.-the storage tank.

__ __ - - - - -- ---- - - - - - - - - - - - - - - - - ~ - - -

Circulating the fuel oil through a 5 micron filter of at least five tank volumes, will provide sufficient cleaning of most normal oxidation and bacteria. If excessive oxidation or bacteria growth occurs, the proposed surveillance test will adequately storage tanks. provide for the surveillance of the diesel generator fuel oil By ensuring that the contamination levels in the storage tanks -

do from that which alreadyliter, not exceed 10mg/ the licensee will improve diesel generator reliability exists.

\ The failure criterion requiring the licensee to completely drain and clean the diesel fuel oil storage tanks will provide an adequate system. path to ensure reasonable reliability of the diesel fuel oil storage Section 4.8.1.1.2.f.2 of the proposed TS requires that the licensee perform a precision leak test to verify the integrity of the fuel system. The leakage

' rate is not to exceed .05 gallons per hour.

The precision leak test employs a fuel surface mounted level detector which operates on the principal of buoyancy changes. The detection system is, reported .

to be able to, detect changes of .05 gallons per hour under worst case conditions.

This approach of surveillance testing the diesel generator fuel oil storage tanks is more conservative than what currently exists in the plants,

f. 2. 3 Concl'usion ' '

The staff believes that the licensee's proposal to pe.rform surveillance testing of the diesel generator fuel oil storage system is more conser'vative than what currently exists in the D. C. Cook Units 1 & 2 TSs. Furthermore, the proposed surveillance method provides sufficient failure and clean tank criterion to prov.ide an increase in diesel generator reliability and thus meets the intent of Generic letter 84-15. The proposed solution to ensure diesel generator fuel oil storage tank cleanliness is, therefore, foiand to be acceptable. It should be noted, however, that the D. C. Cook diesel generator fuel oil storage tank surveillance testing program may be subject to further generic guidance.

2.3 Diesel Generator Surveillance Testino 2.3.1 Introduction

'By a letter dated January 16, 1987, the licensee addressed the diesel generator reliability issue and proposed Technical Specification changes to more closely resemble the Standard Technical Specifications contained in Generic Letter 84-15. *

In a subsequent letter dated November 25, 1987, the licensee provided more previousTS concise changes and answered several NRC originated questions regarding submittals.

The final submittal dated April 6, 1989, provides concise TS changes concerning increased diesel generator reliability. These TS changes also provide uniformity between the D. C. Cook Nuclear Plant Units 1 and 2.

2.3.2 Evaluation Action statement 3.8.1.1.a ~

I This action statement for D. C. Cook Units 1 and 2 currently specifies required actions during the inoperability of one offsite circuit or diesel generator.

In proposing changes to this action statement the licensee has distinguished the loss of an offsite circuit from loss of a diesel generator in the

diesel generator power source will be addressed in a new action str This is consistent with the current Standard Technical Specificatic

delete the requirement of performing 4.8.1.1.2.a.4 once every eight hours

- thereaft'er. The staff finds this change to be consistent with Generic Letter 84-15 and to be acceptable.

Action statement 3.8.1.1.b This new action statement for D. C. Cook Units 1 and 2 is added as a result of the proposed change to action statement 3.8.1.1.a to address loss of a diesel N generator separate from loss of an offsite circuit. As stated in item I above, this proposed change to the TSs is acceptable. The licensee has also proposed to perform the surveillance requirements of 4.8.1.1.2.a.4 on the remaining diesel generator within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months instead of one hour if the diesel generator became inoperable due to any cause other than preplanned preventive maintenance or testing and delete the requirement of performing 4.8.1.1.2.a.4 once every-8 hours thereafter. The staff finds this change to be consistent with Generic ;

Letter 84-15 and to be acceptable.

Additionally the licensee has proposed a 168 hours0.00194 days 0.0467 hours 2.777778e-4 weeks 6.3924e-5 months out-of-service action statement for diesel generator incperability not to exceed an accumulated annu&1 outage time of 576 hours0.00667 days 0.16 hours 9.523809e-4 weeks 2.19168e-4 months in lieu of current TSs requirement of 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months . - '

The staff feels that. at present there are no adequate bases to grant D. C. Cook Units 1 and 2 the requested 168 hours0.00194 days 0.0467 hours 2.777778e-4 weeks 6.3924e-5 months out-of-service period for diesel generators, t Also, the subject of optimum LCOs for safety-related systems is currently a generic study topic for the staff. Therefore, based on the above, we do not reconnend this change to the TSs be granted at this time.

Action statement 3.8.1.1.c This action statement for D. C. Cook Units 1 and 2 currently requires that when one diesel generator and an offsite power circuit are inoperable, the licensee

" should demonstrate the operability of the' remaining diesel generator 'per ~ ~~

surveillance requirement of 4.8.1.1.2.a.4 within one hour and at least once per,,,

The licensee has proposed to demonstrate the diesel generator operability requirement of 4.8.1.1.2.a.4 within eight hours if the diesel generator became inoperable due to any cause other than preplanned li preventive maintenance and testing and to delete the requirement of performing 4.8.1.1.2.a.4 once every eight hours thereafter. The staff finds this change to be consistent with Generic Letter 84-15 and to be acceptable, 3 j

Action statement 3.8.1.1.d ~

requirement of performing 4.8.1.1.2.a.4 once every eight hours thereafter. We find this change consistent with Generic Letter 84-15 and to be acce,ptable.

Action Statement 3.8.1.1.e This action statement for D. C. Cook Units 1 and 2 is currently not part of the TSs. The licensee has proposed to demonstrate the operability of the two remaining A.C. circuits by performing 4.8.1.1.1.a within one hour if both diesel generators become inoperable and restore at least one diesel generator to operable status within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months or be in Hot Standby within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months .

We find this change consistent with Generic Letter 84-15 and acceptable.

The remaining TSs changes to section 3.8.1.1 are administrative in na~ture providing clarity and consistency between both D. C. Cook Unit I and Unit 2 TSs.

TS Section 4,8tl.1.2.a.4 This section for'D. C. Cook Units 1 and 2 currently requires diesel' generator surveillance to be performed from ambient conditions and for the diesel generator to start and accelerate to at least'514 rpm in less than or equal to 10 sec. The proposed change will require starting each diesel generator at least once per 184 days from ambient conditions and accelerating to 514 rpm in less.than or equal to 10 sec. We find this change consistent with Generic Letter 84-15 to improve and maintain diesel generator reliability by reducing the number of cold fast starts of diesel generators and to be acceptable.

c TS Section 4.8.1.1.2.e.2 This section for Unit I currently requires the generator capability to reject a load greater than or equal to 600kW without tripping. The licensee has proposed more conservative requirements including specific voltage and frequency limits that should be met during this test to be consistent with Unit 2 specifications.

This surveillance requirement was accepted by the staff on Unit 2 and is also acceptable for Unit 1.

TS Section 4.8.1.1.2.e.3 .. .

This new specification with respect to the full load rejection test has been added for Unit I specification to be consistent with Unit 2 specifications. I The staff finds the proposed change to be acceptable.

TS Section 4.8.1.1.2.e.4.b og.

This section currently requires that the diesel generator starts on the auto-start signal within 10 seconds, energizes the auto-connected shutdown loads through the load sequencer and operates for greater than or equal to 5 minutes.

The licensee has proposed to add reference to voltage and frequency requirements (for Units 1 and 2) that should be met during this test. The staff finds this change to be more conservative and to be acceptable.

l

I TSs Section 4.8.1.1.2.e.5,6,9 and 10

These specification sections with respect to diesel generator testing have been added for Unit 1 to provide standardization between Unit I and 2 specifications.

The staff-finds these additions to be acceptable. In addition to the above, the '

licensee has proposed to add reference to voltage and frequcncy requirements in

' surveillance requirements of 4.8.1.1.2.e.6.b for Units 1 and 2. The staff finds this'ch'ange to be conservative and to be acceptable. "

~

TSs Section 4.8.1.1.2.e.7 and 8 ,

These sections for Unit 2 currently require that the diesel generator operates for at least 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . During the first two hours of this test, the diesel generator shall be loaded to 3850kW (2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months rating) and during the remaining 22 hours2.546296e-4 days 0.00611 hours 3.637566e-5 weeks 8.371e-6 months of this test, the diesel generator shall be loaded to 3500kW (the continuous rating). The licensee has proposed to perform 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months testing at 3500kW and delete 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months testing at 3850kW. The licensee has stated that D. C. Cook diesel

~

generators'are, rated at 3500kW and do not have 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ratings. The manufacturer of the diesel generators will not support diesel generator operation at 3850kW.

-Moreover, the licensee has demonstrated that the worst case loading of D. C.

Cook diesel geherators is below the continuous rating of 3500kW. Based on the above, the staff concludes that testing of diesel generators at 3500kW for 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months during these surveillance tests is acceptable. In addition, the' licensee has proposed to add Section 4.8.1.1.2.e.7 and revised Section ,4.8.1.1.2.e.8 of Unit 1_TSslto be consistent with Unit 2 TSs. The staff finds thece changes to be acceptable. "

As part of this request, the licensee has also proposed to delete surveillance !'

requirements of 4.8.1.'1.2.c.2 and 4.8.1.1.2.d for Unit 2 and 4.8.1.1.2.b.6 for Unit 1. The surveillance requirement: o f 4. 8.1.1. 2. c. 2 and 4. 8.1.1. 2. b. 6 a re -

' regarding verification of automatic sequence timing relays to assun they are within 15% of its required value and surveillance requirements of 4.8.1.1.2.d is regarding 10 year testing. Based on the information provided by the licensee, the staff concludes that there are no adequate basis to delete these surveillance l requirements _from Unit I and Unit 2 TSs. Therefore, this proposed change to the 1 l

TSs'is denied.

,T_able 4.8.1 & Attachment I and 2 I

" ~ ~ ~

This Table and attachments address reporting and requalification requirements for diesel generators. The licensee has proposed to include this table and -- -

attachments for D. C. Cook Units 1 and 2 TSs. This Table and attachments were l-part of the performance specification included in the Generic Letter 84-15.

The licensees were requested to provide comments on the performance specification for staff.' consideration in finalizing surveillance testing requirements for diesel generators. Subsequently, the NRC staff determined that the actions required by the Table and the Attachment 2 were not necessary and the reporting

. requirements addressed in Attachment I were adequately met by current reporting --

requirements. Therefore, the STS were revised to incorporate the requirements of

-Generic Letter 84-15 and this table and attachments were not included in this revision of the STS. These proposed changes to D. C. Cook Units 1 and 2 TSs are not. required and are therefore denied.

j l

1 l

Table 4.b.2 l This table addresses diesel generator surveillance testing frequency. The present requirement bases the diesel generator test frequency on the number of '

failures in the last 100 tests (for Unit 2 only). The licensee has proposed to l

base the testing. frequency in the last 20 tests. The licensee has also. included this table in Unit 1 TSs to be consistent with Unit 2 TSs. The staff" finds the proposed revised Table 4.8.2 to be consistent with Generic Letter 84-15 and to be acceptable.

In addition to the above proposed TSs changes, the licensee has requested a number of administrative changes to D. C. Cook Units 1 and 2 TSs. These changes are as follows:

A footnote was added on page 3/4 8-2 for Units 1 and 2 to indicate, that as part of the equipment is restored, the plant should return to an early Action '

statement. This transfer statement also clarifies the starting time.-

TS 3.8.2.1 of Unit I was changed to be identical to TS 3.8.2.1 currently approved for, Unit 2. Also, in TS 4.8.2.1 of Unit 1, the phrase "other than the diesel generators" was deleted. In Unit 2 TS 4.8.2.1 the phrase "and energized from A.C. sources" was added for clarity. .

A footnote was added on pages 3/4 8-9 and 8-10 of Units I and 2 to clarify that the 120-volt A.C. Vital buses are energized from their. associated inverter which is connected to a D.C. bus. -

J TS3l8.2.2forUnit1waschangedtobeidenticaltoTS3.8.2.2forUnit2.

Also, in Unit 1.'the phrase "other than the diesel generator" was deleted.

The words "and energized" were added to TS 4.8.2.2 for Unit 2 for clarity.

The qualifier "No" was deleted before the ' letter "N" on page 3/4 8-16 for Units 1 and 2. This qualifier serves no purpose. '

)

The word "value" is now written each time rather than being indicated by ditto marks on page 3/4 8-12 for Units 1 and 2.

Throughout Section 3/4-8 for Units 1 and 2 hyphens were added where appropriate and the word " greater (or less) than or eduall to" were used to replac'e the ' '

mathematical symbols. In addition, the page numbers and table numbers for TS . ,

Section 3/4-8 for both were revised for both units due to the addition of a number of new pages to accommodate the proposed changes. l The staff finds the above administrative changes to be acceptable.

3.0 ENVIRONMENTAL CONSIDERATION

~

l This amendment involves a change in the installation and use of a facility l

component located within the restricted area as defined in 10 CFR part 20 and a change to the surveillance requirements. The staff has determined that the

) amendments involve no significant increase in the amounts, and no significant l change in the types, of any effluents that may be released offsite, and that l there.is no significant increase in individual or cumulative occupational

l radiation exposure.

The commission has previously issued a proposed finding that these amendments involve no significant hazards consideration and there {

has been no public comment on such finding. Accordingly, these ainendments j meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact . statement of environmental assessment need be prepared in connection with the issuance of this, amendment.

4.0 CONCLUSION

We have concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, (3) and the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public. .
