1.0 INTRODUCTION
By application dated December 11, 2001, Southern California Edison Company, et al., (SCE or the licensee), requested changes to the Technical Specifications (TS) for San Onofre Nuclear Generating Station (SONGS), Units 2 and 3. The proposed changes would revise TS 3.8.3, Diesel Fuel Oil, Lube Oil, and Starting Air, to change the minimum required amount of stored diesel fuel. The licensee indicated that the proposed changes are required to support the use of California Diesel fuel rather than the existing Environmental Protection Agency (EPA) Clear diesel fuel, and reflect a change in the diesel generator load profile in Modes 1 through 4.
The licensee proposed to revise TS 3.8.3, Conditions A and C, and surveillance requirement (SR) 3.8.3.1, to express the 7-day and 6-day fuel volume requirements in gallons rather than percent tank level.
Specifically, the licensee proposed to revise:
(1)
TS 3.8.3, Condition A, to specify that during Modes 1 through 4, if one or more diesel generators (DGs) has a fuel volume in the storage tank less than 45,662 gallons (instead of 89 percent level) and greater than 39,468 gallons (instead of greater than or equal to 76 percent level), then fuel oil level must be restored to within limits within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
(2)
TS 3.8.3, Condition C, to specify that during Modes 5 and 6, if one DG has a fuel volume in the storage tank less than 41,691 gallons (instead of 72 percent level) and greater than 35,735 gallons (instead of greater than or equal to 63 percent level), then fuel oil level must be restored to within limits within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
The volumes specified above do not include allowances for instrument uncertainty.
(3)
SR 3.8.3.1 to verify the above specified fuel volume every 31 days instead of levels.
(4)
TS 3.8.3 Conditions A and C to change the "greater than or equal to" sign to a "greater than" sign for consistency with the rest of the specification.
(5)
TS Bases 3.8.3 to reflect the above proposed TS changes.
The new requirements will continue to ensure that sufficient fuel is available to supply loads for the necessary time periods (7-day, and 6-day supply).
2.0 REGULATORY ANALYSIS
Appendix A to 10 CFR Part 50, General Design Criterion, Criterion 17, Electric power systems, requires :
An onsite electric power system and an offsite electric power system shall be provided to permit functioning of structures, systems, and components important to safety. The safety function for each system (assuming the other system is not functioning) shall be to provide sufficient capacity and capability to assure that (1) specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary are not exceeded as a result of anticipated operational occurrences and (2) the core is cooled and containment integrity and other vital functions are maintained in the event of postulated accidents.
American National Standards Institute (ANSI) standard ANSI 195/ANS 59.51, "Fuel Oil Systems for Standby Diesel Generators," requires that the onsite fuel oil storage shall be sufficient to operate the minimum number of DGs following the limiting design-basis accident for either seven (7) days, or the time required to replenish the oil from the sources outside the plant site following any limiting design-basis event without interrupting the operation of the diesel, whichever is longer.
3.0 EVALUATION SONGS, Units 2 and 3 design includes an onsite power system consisting of one DG for each safety-related load group (two per unit) complete with accessories, fuel storage, and transfer systems. Each DG is provided with sufficient stored diesel fuel oil to operate the DG for a period of 7 days, while the DG is supplying maximum post-loss-of-coolant accident (LOCA) load demand.
Presently, SONGS uses EPA Clear diesel fuel. SONGS is required by California State regulation as implemented by the San Diego Air Pollution Control District to discontinue use of the current EPA Clear diesel fuel and replace it with California Diesel fuel for emissions purposes. The California Diesel fuel has slightly lower heating value (LHV) per gallon basis compared to the existing EPA Clear diesel fuel. As a result, a larger quantity of diesel fuel will be required to ensure a 7-day or 6-day supply of fuel is available for each DG.
In addition, the licensee has revised fuel volume calculations to reflect a change to the diesel generator load profile in Modes 1 through 4 in accordance with the provisions of 10 CFR 50.59.
The existing fuel volume calculations assumed operation of the third-of-a-kind High Pressure Safety Injection (HPSI) pump under post-accident conditions. Operation of the third-of-a-kind HPSI is no longer required under these conditions. Removal of this load from the post-accident load profile has decreased the overall required volumes of fuel in the tank for Modes 1 through 4, even when use of the new fuel is taken into account. The NRC staff did not review the DG load profile changes which were made in accordance with 10 CFR 50.59.
Using the methods described in ANSI 195/ANS 59.51, and based on the LHV of California Diesel fuel, and the revised post-accident load profile, the licensee has re-calculated the minimum required volume of fuel necessary to ensure a 7-day or 6-day supply of fuel is available for each DG. Based on the revised calculations, the licensee has determined that the amount of stored fuel required to ensure a sufficient supply of fuel in Modes 1 through 4 will be decreased from 49,724 gallons to 45,662 gallons (7-day supply of fuel), and from 42,960 gallons to 39,468 gallons (6-day supply of fuel). The minimum amount of fuel in Modes 5 and 6 will be increased from 40,472 gallons to 41,691 gallons (7-day supply of fuel) and from 34,690 gallons to 35,735 gallons (6-day supply of fuel).
Because the revised volume of stored diesel fuel oil is sufficient to operate the DG for a required period of 7 or 6 days, as applicable, while the DG is supplying maximum post-LOCA load demand, the proposed changes are acceptable. The change of units for the minimum required diesel fuel from tank level (percent) to volume (gallons), and the "greater than or equal to" sign to greater than in TS 3.8.3, are administrative in nature and have no impact on the safe operation of the DGs. Therefore, these changes are acceptable.
Because the new values are expressed in gallons, these values need not include allowances for instrument uncertainty. However, the licensee indicated that instrument uncertainty will continue be included in calculations to determine corresponding tank levels for use in control room alarm setpoints and surveillance procedures.
Following implementation of these proposed changes, there will be no change in the ability of the diesel fuel oil storage and transfer system to supply the diesel generators over the required 7-day and 6-day periods and, therefore, the NRC staff finds the proposed changes to be acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the California State official was notified of the proposed issuance of the amendments. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendments change a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes a surveillance requirement. The NRC staff has determined that the amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on such finding (67 FR 932 dated January 8, 2002). Accordingly, the amendments 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 or environmental assessment need be prepared in connection with the issuance of the amendments.
6.0 CONCLUSION
The Commission has 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
December 17, 2001 Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
