1.0 INTRODUCTION
By letter dated May 2, 2008, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML081230594), Exelon Generation Company, LLC, (the licensee),
submitted a license amendment request for LaSalle County Station (LSCS) Units 1 and 2. The proposed amendment would modify the Technical Specification (TS) requirements related to Diesel Fuel Oil and Starting Air by replacing the specific fuel oil volumes with a requirement to maintain greater than or equal to a 7 day and a 6 day supply for the diesel fuel oil while retaining the specific tank volumes needed to meet the 7 day and 6 day requirements in the TS Bases.
By letter dated July 23, 2008, ADAMS Accession No. ML082060176, the licensee responded to the staff's request for additional information.
The July 23, 2008, supplement, contained clarifying information and did not change the U.S.
Nuclear Regulatory Commission (NRC) staff's initial proposed finding of no significant hazards consideration.
2.0 REGULATORY EVALUATION
Section 182a of the Atomic Energy Act requires applicants for nuclear power plant operating licenses to include TSs as part of the license. These TSs are derived from the plant safety analyses.
The onsite electrical power system includes standby power sources, distribution systems, and vital auxiliary supporting systems to supply power to safety-related equipment. Most commercial nuclear power plants use diesel generators as the emergency power source for the safety related electrical buses. The importance of the diesel generators (or other standby power sources) is reflected in their incorporation into NRC regulations, TS, and other regulatory programs, including General Design Criterion (GDC) 17 ("Electric Power Systems") of Appendix A ("General Design Criteria for Nuclear Power Plants") and Appendix B ("Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants) to Part 50 of Title 10 of the Code of Federal Regulations (10 CFR Part 50).
- 2 Regulatory Guide (RG) 1.137, Regulatory Position 1, states that American National Standards Institute (ANSI) N195-1976, "Fuel Oil Systems for Standby Diesel-Generators" provides a method acceptable to the staff for complying with the pertinent requirements of GDC 17 of Appendix A to 10 CFR Part 50. Regulatory Position 1.c states that Section 5.4 of ANSI N195-1976, "Calculation of Fuel Oil Storage Requirements," sets forth two methods for the calculation of fuel oil storage requirements. These two methods are (1) calculations based on the assumption that the diesel generator operates continuously for 7 days at its rated capacity, and (2) calculations based on the time-dependent loads of the diesel generator. For the time dependent load method, the minimum required capacity should include the capacity to power the engineered safety features. It is stated in Paragraph 1.1.H of Section 9.5.4 of NUREG 0800 that "a minimum of seven days supply of fuel oil for each diesel generator system is onsite to meet the engineered safety feature load requirements following a loss of offsite power and a design basis accident.
The application of this general framework is discussed in Section 3.0 for the specific proposed changes.
3.0 TECHNICAL EVALUATION
The proposed amendment would modify the TS requirements related to Diesel Fuel Oil and Starting Air by replacing the specific fuel oil storage volumetric requirements (in gallons) with a requirement to maintain less than a 7 day supply and greater than or equal to a 6 day supply for the diesel fuel oil while retaining the specific tank vOlumetric requirements (in gallons) needed to meet the 7 day and 6 day requirements in the TS Bases. These specific tank volumetric requirements for the Division 1, Division 2, and opposite unit Division 2 emergency diesel generators (EDGs) include a minimum of 250 gallons of fuel oil in the associated fuel oil day tank. For the Division 3 EDG a minimum of 550 gallons of fuel oil in the day tank is included in the 7 and 6 day volumetric requirements.
The requested changes to the Diesel Fuel Oil and Starting Air TS (LCO 3.8.3) ensure that the information required by 10 CFR 50.36 is maintained in the TS and that the specific design value for volume that needs to be maintained in the fuel oil storage tanks and day tanks (in gallons) are located in a licensee-controlled document (i.e., the TS Bases). The licensee's TS Bases are controlled in accordance with TS 5.5.11, "Technical Specifications (TS) Bases Control Program."
The licensee's TS currently have the specific amounts (in gallons) of fuel oil necessary for each EDG for 7 days and 6 days of continuous operation. These specific amounts are located in both the Limiting Conditions for Operation (LCO) and the Surveillance Requirements. The licensee proposes to replace these specific amounts of fuel oil with the required amount of time (7 days and 6 days). The specific amounts of fuel oil would be relocated to the TS Bases. The specific amounts of fuel are based on the properties of Ultra Low Sulfur Diesel (ULSD) fuel.
The Environmental Protection agency has finalized the Clean Diesel Trucks and Buses Rule and the Clean l\\Ionroad Diesel Rule. These rules require sulfur reductions for land-based nonroad diesel fuel to be accomplished in two steps, with an interim step from currently uncontrolled sulfur content levels to a 500 parts per million (ppm) cap starting in June 2007, and the final step to 15 ppm sulfur content in June 2010. This 15 ppm sulfur content fuel is known as ULSD. The processing required to reduce the sulfur content to 15 ppm also reduces the aromatic content and the density of diesel fuel, which results in a reduction in vOlumetric energy content (British
- 3 Thermal Unit per gallon). This reduction in energy content will require the licensee to store more fuel in order to maintain an amount sufficient for 7 days of EDG operation.
As stated above, RG 1.137, Regulatory Position 1, states that ANSI N195-1976 provides a method acceptable to the staff for complying with the pertinent requirements of GDC 17 of Appendix A to 10 CFR Part 50. Regulatory Position 1.c states that Section 5.4 of ANSI N195-1976 sets forth two methods for the calculation of fuel oil storage requirements. The licensee's calculation follows the first of the two methods for determining the fuel oil storage requirements.
The licensee has calculated the required amount of stored fuel for 7 days and 6 days of EDG operation considering all ULSD across the allowable American Petroleum Institute (API) gravity band of 27 to 39, which is the API gravity band allowed by the LSCS Diesel Fuel Oil Testing Program. This evaluation determined that the maximum mass of fuel would be required when considering the properties of ULSD at an API gravity of 27 at 50°F. Since the measured fuel oil storage tank level is converted to gallons, and the licensee's fuel is ordered by the gallon, the licensee converted the maximum required mass of fuel to gallons using an API gravity of 30 at 60°F. The correlation between API gravity and energy content is well known. This correlation is documented by the National Bureau of Standards in their Miscellaneous Publication No. 97, "Thermal Properties of Petroleum Products," dated April 28, 1933.
Relocating the specific values of fuel oil equivalent to 7 and 6 day supplies to the TS Bases does not alter the licensing basis of the plant. The licensee is still required by TS to maintain these 7 and 6 day supplies. The proposed amendment will allow the licensee to adjust these specific values based on the properties of the fuel oil received without having to submit a license amendment request.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Illinois State official was notified of the proposed issuance of the amendments. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendments change requirements with respect to the installation or use of the facilities components located within the restricted area as defined in 10 CFR Part 20. 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 (73 FR 46930; dated August 12, 2008). 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 licensee's proposed changes in this license amendment request are acceptable since the changes to LSCS TS requirements do not result in any substantive change in operating requirements, are consistent with the Commission's regulations, and conform to the requirements of 10 CFR 50.36. On this basis, the NRC staff concludes that the proposed TS changes are acceptable.
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 amendments will not be inimical to the common defense and security or to the health and safety of the public.
