1.0 INTRODUCTION

j':

In a letter dated July 27, 1989, South Carolina Electric & Gas Company (the licensee) submitted a proposed change to Surveillance. Requirement 4.8.1.1.'2 of Technical Specification (TS) 3/4.8.1 A. C. Sources. The initial request was. supplemented by submittals dated September. 21, 1989,

. April 10, 1990 and May-29, 1990; which provided clarifying information.

i that did not affect the staff's proposed no significant hazards consideration determination.

(

Surveillance Requirement 4.8.1.1.2 requires that each diesel generator be demonstrated OPERABLE "by obtaining a' sample of fuel oil in accordance-with ASTM D270-1975 at.least once per 92 days and prior to the addition of new fuel oil to the storage tanks...."

The purpose of demonstrating the operability of the diesel generators-is to ensure that: sufficient power will be available to supply the safety related equipment required y

for the-safe shutdown'for the facility and the mitigation and control of I

accident conditions within the.f acility. The diesel fuel oil monitoring.

L-and analyses requirements-in Surveillance Requirement 4.8.1.1.2 ensure.

1; that the quality of the oil meets the.NRC guidelines on kinematic viscosity, water and sediment control, and: specific gravity, per Regulatory Guide 1.137 Revision 1, " Fuel Oil Systems for. Standby Diesel Generators," October 1979. The licensee has proposed a change to L

Surveillance Requirement 4.8.1.1.2 by deleting the existing item c and replacing.it with the standard requirements delineated in NUREG-0452,

" Standard Technical Specifications for Westinghouse Pressurized Water Reactors"(STS).

In addition, the licensee has proposed an additional requirement to check for and remove any accumulated water in the fuel oil L

storage tanks every 31 days. This addition 1s also included in NUREG-0452.

- 2.0- EVALUATION The licensee is proposing this -change to the Suniner TS on testing

. methodology and acceptability of emergency diesel generator fuel oil to comply with the laiest ASTM test standards and to bring their TS into confonnance with the STS.

Changes which the licensee has proposed-include:

1.

Addition of a new requirement to check for and remove any accumulated water in the -fuel oil storage tank every 31 days;

-2.

Deletion of the requirement for sampling of the fuel oil once per 92 days; 3.

Obtaining. the fuel oil sample per ASTM 04057-81 versus ASTM

'D270-75 which was discontinued in 1984; L

4.

Analysis of the fuel oil sample in accordance with ASTM D975-

'l 81, Appendix XI in place of ASTM 0975'1977 with exceptions taken to the monitoring program specified in Appendix X.3 of l

ASTM D975-81 such that:

a)' sampling will be performed in accordance with ASTM D4057-81; i

.b) insoluble-fuel contaminants will be determined using ASTM 02276-88 with sampling as specified in the method; and c). the fual stability test (ASTM D-2274) will not be performed.

I

~5.

Adds a requirement for a " clear and bright appearance with proper color" test per ASTM D4176-82; L

6.

Changes the flash point test to require it only prior to addition of new fuel.to tanks and not once per 92 days; 17. Deletes requirennt for a water and sediment content test; 8.

Verification of kinematic viscosity can be demonstrated by.

showing that the Saybolt Viscosity is within a specified range; 9.

Verification that specific gravity or API gravity is within a l

specified range within the specified tolerance of the supplier's l

certificate allowing two additional alternative methods for H

verification.-

10. Within 30 days of obtaining a sample, rather than two weeks, the l

L

. properties specified in Table 1 of ASTM D975-1981, rather than I

the properties specified in Table 1 of ASTM 0975-1977 and Regulatory Guide 1.137, Position 2.a. will be verified and 1

' tested in accordance with the 1981 version of ASTM D975, rather than the 1977 version.

An exceptico will be that the sulfur analysis will be performed in accordance with either ASTM D1552-79 or ASTM D2622-82;

11. Sampling and analysis of fuel oil once every 31 days in accordance with ASTM 02276-88 Lithod A that the particulate contamination is less than 10 mg/ liter; 12.

Deletion of verification that within one week of obtaining a sample of fLel oil, the sample will have an impurity level of less than ? mg of incoluble per 100 ml when tested per ASTM D2274-70; and 13.

Relettering of cections d, e, f, and g o Surveillance Requirement 4.8.1.1.2.

The licensee indicated t.1e proposed changes would bring the Sumer Surveillance Requirements for diesel fuel oil monitoring and analysis into conformance with the Westinghouse STS and would ensure proper quality-fuel oil for the operation of the diesel generators.

The licensee also indicated that there was no difference between the sampling and analysis requirements contained in the 1981 version of ASTM 0975 and the-1977 version. -The oxidation stability analysis in the present TS is being replaced by. a total particulate contamination analysis, as includeo

'in.the Westinghouse STS. The deletion of'the oxidation stability analysis is considered an improvement because the analysis is considered hazardous and the analysis is time consuming.

In addition, the results of the. stability test are not indicative of the actual conditions in the tanks.

Results of the total particulate contamination tests performed by chemistry personnel at the V. C. Summer Nuclear Station have proven satisfactory.

The staff revieweo the licensee's submittal and did not conclude that the proposed changes bro @t the Sumer TS into agreament with the Westinghouse STS. Hcwever, the changes are consistent with the TSs issued for such recent licensees as Commache Peak, Sotth Texas, and Vogtle.

The staff has reviewed these changes and has concluded that the changes will continue to ensure that the quality of the diesel generator fuel oil will be maintained and thereby ensure that sufficient power will be provided-for the safety-re)ated equipment required for safe shutdown of the reactor and far ti:e mitication and control of accident conditions within the facility. lne staff has, therefore, determined that the licensee's request is acceptable.

3.0 ENVIRONMENTAL CONSIDERATION

This amendment involves a change to a requirement with respect to the installation or use of a facility component located within the restricted area as defined in the 10 CFR Part 20 and changes to the surveillance requirements.

The staff has determined that the amendment involves no significant ncrease in the amounts, and no significant change in the l

3

..3'

~

r types of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiction exposure. The Commission has previously issued a proposed finding that this amendment involves no significant hazards consideration, and there has been no public connent on such finding. Accordingly, this amendment meets the elig)ibility criteria for categoric.a1 exclusion set forth in 10 CFR 51.22(c)(9.

Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental ~ assessment need be prepared in connection with the issuance of this amendment.

4.0 CONCLUSION

.l 1

The Commission has issued a " Notice of Consideration of Issuance of Amendment-to Facility Operating License and Propose No Significant i

Hazards Consideration Determination and Opportunity for Hearing" which was published in the FEDERAL REGISTER on January 10, 1990 (55 FR 939) and consulted with the State of South Carolina.

No pc511c comments or i

requests for hearing were received, and the State of South Carolina did not have comments.

The staff has concluded, based on the considerations discussed above,.

that:

(1) there is reasonable assurance that the health and safety of the publicwillnotbeendangeredbyoperationintheproposedmanner,-(2)

such activities will be conducted in compliance with the Commission's regulations, and.(3) the issuance of this amendment will not be inimical to tne comon defense and security or to the health and safety of the public.
