1.0 INTRODUCTION
By letter dated August 24, 2007 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML072400401), Exelon Generation Company, LLC (Exelon, the licensee) requested changes to the Technical Specifications (TSs) for Limerick Generating Station (LGS), Units 1 and 2. By letter dated June 11, 2008 (ADAMS Accession No. ML081630558), a revised license amendment request (LAR) was submitted, where most of the changes proposed in the original license amendment request were withdrawn. The revised LAR proposes to change the required emergency diesel generator (EDG) day tank volume from a minimum of 200 gallons to a minimum of 250 gallons. The U.S. Nuclear Regulatory Commission (NRC or Commission) staff=s proposed no significant hazards consideration determination for this change was published in the Federal Register on June 20, 2008 (73 FR 35168) and was based on the revised LAR.
The reason for this proposed change is to account for factors contained in a new LGS design analysis that address the variation of fuel heat content with specific gravity, account for parasitic engine driven shaft loads, address generator efficiency, and also include a specific allowance for the reduction in fuel oil heat content associated with the introduction of ultra low sulphur diesel (ULSD) fuel oil.
2.0 REGULATORY EVALUATION
General Design Criterion (GDC) 17, "Electric Power Systems," of Appendix A, "General Design Criteria for Nuclear Power Plants," to Title 10 of the Code of Federal Regulations (10 CFR) Part 50, "Domestic Licensing of Production and Utilization Facilities," requires that an onsite electric power system and an offsite electric power system be provided to permit functioning of structures, systems, and components important to safety. In addition, GDC 17 contains requirements concerning system capacity, capability, independence, redundancy, availability, testability, and reliability. LGS complies with GDC 17 as detailed in the Updated Final Safety Analysis Report (UFSAR), Sections 3.1 and 8.3.1.2.1.4.
The onsite electrical power system includes standby power sources, distribution systems, and vital auxiliary supporting systems to supply power to safety-related equipment. LGS, Units 1 and 2, uses diesel generators as the emergency power source for the safety-related electrical buses. The importance of the EDGs is reflected in their incorporation into the plant TSs, and other regulatory programs, including Appendix B (Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants) to 10 CFR Part 50. Important support system parameters for the LGS EDGs, such as the fuel oil supply system, are likewise incorporated into the plant TSs in accordance with 10 CFR 50.36 (d)(2)(ii)(C) and 10 CFR 50.36 (d)(3).
The LGS UFSAR also details specific requirements for the EDG fuel oil system. UFSAR Section 1.8 discusses LGS conformance with Regulatory Guide (RG) 1.137, Fuel Oil Systems for Standby Diesel Generators, revision 1, October 1979, which endorses/modifies ANSI N195-1976, Fuel Oil Systems for Standby Diesel-Generators. LGS is only committed to paragraph C.2 of this RG, which specifies requirements for fuel oil quality. LGS is thus not directly committed to the section of ANSI N195-1976 that specifies EDG day tank volume. However, requirements for LGS fuel oil system design are specified in UFSAR Section 9.5.4.2 and require that, in the unlikely event of a fuel oil system supply failure, the associated day tank low level alarm will provide approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> of full load operation so that the operator can take corrective action to prevent loss of the diesel. The 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> requirement for day tank volume specified in the LGS UFSAR is comparable to the day tank volume requirement of ANSI N195-1976. This 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> requirement is reflected in the LGS TSs, Sections 3.8.1.1 and 3.8.1.2, converted to a volume specification. The minimum day tank volume is needed to support operability of the associated EDG.
3.0 TECHNICAL EVALUATION
The initial conditions of design-basis accident (DBA) analyses assume engineered safety feature (ESF) systems are operable. The EDGs are designed to provide sufficient capacity, capability, redundancy and reliability to ensure availability of necessary power to ESF systems so that nuclear fuel, reactor coolant system and primary containment design limits are not exceeded.
To support this mission, an adequate quantity of fuel oil needs to be maintained in the EDG day tanks so that adequate time is available to respond to a failure of the fuel transfer system to prevent loss of the diesel.
Each of the EDGs is capable of supplying one of the four load divisions on each unit. Any combination of three-out-of-four divisions is acceptable for a single failure. Each EDG is physically and electrically independent from the other and any offsite power source. Each EDG fuel oil supply consists of an 850-gallon day tank that provides a suction source for the EDG fuel pumps, which in turn supply fuel to the engine injectors. Makeup to each day tank is accomplished automatically from a 41,500 gallon fuel storage associated with the EDG. Fuel oil is transferred from the storage tank to the day tanks by diesel oil transfer pumps. The transfer pump motors receive electrical power from the same electrical division as the diesel generator it supplies. The day tank has sufficient capacity to supply the EDG for more than 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> of continuous operation at rated load. Should the day tank supply system fail, a low level alarm will annunciate when the fuel oil remaining in the tank will provide approximately 1 more hour of rated operation so that the operator can take corrective action to prevent loss of the EDG. The level at which the day tank is maintained by the fuel oil supply control system is above the low alarm setpoint and thus the operator would know that receipt of a low level alarm means there is a problem with the fuel oil supply system.
The current volume of fuel oil required to support an EDG operating for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> at the continuous rating of 2850 kilowatts (Kw) is specified at 200 gallons in the LGS TSs. Based on a station re-analysis of factors that could impact fuel consumption, including the use of ULSD fuel, the
licensee has concluded that this TS requirement is non-conservative. The 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> fuel consumption rate could be as high as 220 gallons per hour at continuous rated load. After applying a margin of 10 percent, as recommended by ANSI N195-1976, the licensee concluded that 242 gallons of fuel oil is required to maintain the 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> basis of operation that is specified in the UFSAR and therefore proposes a new 250 gallon TS requirement. Since the oil level in the day tank is controlled above the new proposed 250 gallon requirement, and the low level alarm annunciates at a level above the new requirement, no setpoint changes, plant modifications or changes to EDG operation will be required as a result of the higher required minimum volume.
The proposed change in EDG day tank minimum volume maintains the original licensing basis requirement as specified in the LGS UFSAR, of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> of continuous operation at rated load after receipt of the low level alarm. Even though the licensee is not fully committed to the oil storage requirements of ANSI N195-1976, the new EDG day tank TS volume requirement also meets the requirements of that standard since the automatic day tank fuel oil supply system maintains a higher level in the tank than is necessary to support 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> of operation of the engine at rated load. Thus, the proposed change meets both the plant licensing basis and the standard that the NRC finds acceptable for evaluating the compliance of diesel fuel systems with GDC 17. Additionally, the proposed change is in the more restrictive (conservative) direction as compared to the current TS minimum. Based on these considerations the NRC staff finds the proposed change acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Pennsylvania State official was notified of the proposed issuance of the amendment. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves 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 amendment involves no significant hazards consideration, and there has been no public comment on such finding (73 FR 35168). Accordingly, the amendment meets 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 amendment.
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 Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
