==1.0 DESCRIPTION==
 
The proposed amendment would modify technical specifications by relocating references to specific American Society for Testing and Materials (ASTM) standards for fuel oil testing to licensee-controlled documents and adding alternate criteria to the "clear and bright" acceptance test for new fuel oil.The changes are consistent with Nuclear Regulatory Commission (NRC) approved Industry/Technical Specification Task Force (TSTF) TSTF-374 Revision 0. The availability of this TS improvement was published in the Federal Register on February 22, 2006 as part of the consolidated line item improvement process (CLIIP).2.0 ASSESSMENT
 
===2.1 Applicability===
 
of TSTF-374, and Published Safety Evaluation Florida Power and Light (FPL) has reviewed TSTF-374 (Reference 1), and the NRC model safety evaluation (SE) (Reference
: 2) as part of the CLIIP. FPL has concluded that the information in TSTF-374, as well as the SE prepared by the NRC staff are applicable to St. Lucie, Units 1 and 2, justify these amendments for the incorporation of the changes to the St. Lucie TS. FPL confirms that the changes proposed for Combustion Engineering are applicable to the St. Lucie TSs.2.2 Optional Changes and Variations The St. Lucie TSs are custom TSs, therefore, FPL is proposing conforming changes to ensure that the amendment request meets the intent of the TS changes described in the TSTF-374 (Reference 1).The St. Lucie TSs do not currently contain a diesel fuel oil testing program in the administrative TS section. This amendment will make conforming changes to the administrative section of the St. Lucie TS to incorporate the ISTS (Reference 3)Diesel Fuel Oil Testing Program.* The St. Lucie administrative TS are located in Section 6.0 of the TSs, and the diesel fuel oil testing program will be incorporated in Section 6.0 of the St. Lucie TSs.Because the current St. Lucie TSs do not contain administrative TSs for governing the Diesel Fuel Oil Testing Program, the diesel fuel oil test requirements are contained as surveillance requirements in the Electrical Power System A.C. Sources TSs. This amendment will essentially relocate the existing surveillance requirements from the Electrical Power System A.C. Sources TS to the administrative diesel fuel oil testing program TS and TS Bases consistent with TSTF-374.
St. Lucie Units 1 and 2 L-2008-120 Docket Nos. 50-335 and 50-389 Attachment 1 Proposed License Amendments Page 2 of 3 Diesel Fuel Oil Test Program TSTF-374 This amendment request does not alter the current licensing bases for the referenced ASTM code years.Although the nature of the St. Lucie custom TSs do not allow wholesale adoption of the TSTF format, this amendment request ensures that the proposed deviations are administrative in nature and that the intent of the changes are consistent with TSTF-374 (Reference
: 1) and the NRC staff s model safety evaluation (Reference 2).3.0 REGULATORY ANALYSIS 3.1 No Significant Hazards Consideration Determination FPL has reviewed the proposed no significant hazards consideration determination (NSHCD) published in the Federal Register as part of the CLIIP. FPL has concluded that the proposed NSHCD presented in the Federal Register notice is applicable to St. Lucie and is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).3.2 Verification and Commitments As discussed in the notice of availability published in the Federal Register on February 22, 2006 for this TS improvement, plant-specific verifications were performed as follows: FPL has proposed TS Bases consistent with TSTF-374, which provide guidance and details on how to implement the new requirements.
In addition, FPL has a Bases Control Program consistent with Section 5.5 of the Standard Technical Specifications (STS).4.0 ENVIRONMENTAL EVALUATION The amendment changes requirements with respect to the 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 adopting TSTF-374, Rev 0, 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 individuial or cumulative occupational radiation exposure.
The Commission has previously issued a proposed finding that TSTF-374, Rev 0, involves no significant hazards considerations, and there has been no public comment on the finding in Federal Register Notice 70 FRN 9179, February 22, 2006 (Reference 2). 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.

BASES (continued)
TS 3.8.1.1, ACTION "b" provides an allowed outagelaction completion time (AOT) of up to 14 days toto restore a single inoperable diesel generator to operable status. This AOT is based on the findings of a deterministic and probabilistic safety analysis and is referred to as a "risk-informed" AOT.Entry into this action requires that a risk assessment be performed in accordance with the Configuration Risk Management Program (CRMP), which is described in the Administrative Procedure that implements the Maintenance Rule pursuant to 10 CFR 50.65.All EDG inoperabilities must be investigated for common-cause failures regardless of how long the EDG inoperability persists.
When one diesel generator is inoperable, required ACTIONS 3.8.1.1.b and 3.8.1.1.c provide an allowance to avoid unnecessary testing of EDGs. If it can be determined that the cause of the inoperable EDG does not exist on the remaining OPERABLE EDG, then SR 4.8.1.1.2.a.4 does not have to be performed.
Eight (8) hours is reasonable to confirm that the OPERABLE EDG is not affected by the same problem as the inoperable EDG. If it cannot otherwise be determined that the cause of the initial inoperable EDG does not exist on the remaining EDG, then satisfactory performance of SR 4.8.1.1.2.a.4 suffices to provide assurance of continued OPERABILITY of that EDG.If the cause of the initial inoperability exists on the remaining OPERABLE EDG, that EDG would also be declared inoperable upondiscovery, and ACTION 3.8.1.1 .e would be entered. Once the failure is repaired (on either EDG), the common-cause failure no longer exists.Ambient conditions are the normal standby conditions for the diesel engines. Any normally running warmup systems should be in service and operating, and manufacturer's recommendations for engine oil and water temperatures and other parameters should be followed.The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that 1) the facility can be maintained in the shutdown or refueling condition for extended time periods and 2) sufficient instrumentation and control capability is available for monitoring and maintaining the facility status.
St. Lucie Units 1 and 2 L-2008-120 Docket Nos. 50-335 and 50-389 Attachment 5 Proposed License Amendments Page 3 of 7 Diesel Fuel Oil Test Program TSTF-374 INSERT A 4.8.1.1.2.c requires verification that the fuel oil properties of new and stored fuel oil are tested in accordance with, and maintained within the limits of the Diesel Fuel Oil Program.The tests listed below are a means of determining whether new fuel oil is of the appropriate grade and has not been contaminated with substances that would have an immediate, detrimental impact on diesel engine combustion.
If results from these tests are within acceptable limits, the fuel oil may be added to the storage tanks without concern for contaminating the entire volume of fuel oil in the storage tanks. These tests are to be conducted prior to adding the new fuel to the storage tank(s), but in no case is the time between receipt of new fuel and conducting the tests to exceed 31 days. The tests, limits, and applicable ASTM Standards are as follows: a. Sample the new fuel oil in accordance with ASTM D4057, b. Verify in accordance with the tests specified in ASTM D975 that the sample has an absolute specific gravity at 60/60'F of > 0.83 and < 0.89, or an API gravity at 60'F of >270 and < 390 when tested in accordance with ASTM D1298, a kinematic viscosity at 40'C of> 1.9 centistokes and < 4.1 centistokes, and a flash point > 125&deg;F, and c. Verify that the new fuel oil has a clear and bright appearance with proper color when tested in accordance with ASTM D4176 or a water and sediment content within limits when tested in accordance with ASTM D2709.Failure to meet any of the above limits is cause for rejecting the new fuel oil, but does not represent a failure to meet the LCO concern since the fuel oil is not added to the storage tanks.Within 31 days following the initial new fuel oil sample, the fuel oil is analyzed to establish that the other properties specified in Table 1 of ASTM D975 are met for new fuel oil when tested in accordance with ASTM D975, except that the analysis for sulfur may be performed in accordance with ASTM D1 552, ASTM D2622, or ASTM D4294.The 31 day period is acceptable because the fuel oil properties of interest, even if they were not within stated limits, would not have an immediate effect on DG operation.
This Surveillance ensures the availability of high quality fuel oil for the DGs.Fuel oil degradation during long term storage shows up as an increase in particulate, due mostly to oxidation.
The presence of particulate does not mean the fuel oil will not burn properly in a diesel engine. The particulate can cause fouling of filters and fuel oil injection equipment, however, which can cause engine failure.Particulate concentrations should be determined in accordance with ASTM D5452.

The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that 1) the facility can be maintained in the shutdown or refueling condition for extended time periods and 2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.The Surveillance Requirements for demonstrating the OPERABILITY of the.diesel generators are in accordance with the recommendations of yN -Regulatory Guide 1.9 "Selection of Diesel Generator Set Capacity for ISERT B Standby Power Supplies," March 10, 1971, and 1.108 "Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977, and 1.137, "Fuel Oil Systems for Standby Diesel Generators," Revision 1, October 1979, Generic Letter 84-15, "Proposed Staff Actions to Improve and Maintain Diesel Generator Reliability," dated July 2, 1984, and NRC staff positions reflected in Amendment No. 48 to Facility Operating License NPF-7 for North Anna Unit 2, dated April 25, 1985; as modified by Generic Letter 93-05, "Line-Item Technical Specifications Improvements to Reduce Surveillance Requirements for Testing During Power Operation," dated September 27, 1993, and Generic Letter 94-01, "Removal of Accelerated Testing and Special Reporting Requirements for Emergency Diesel Generators," dated May 31, 1994.The Surveillance Requirement for demonstrating the OPERABILITY of the Station batteries are based on the recommendations of Regulatory Guide.1.129, "Maintenance Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants," February 1978, and IEEE Std 450-1980, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations." Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connection resistance values and the performance of battery service and discharge tests ensures the effectiveness of the charging system, the ability to handle high discharge rates and compares the battery capacity at that time with the rated capacity.

If results from these tests are within acceptable limits, the fuel oil may be added to the storage tanks without concern for contaminating the entire volume of fuel oil in the storage tanks. These tests are to be conducted prior to adding the new fuel to the storage tank(s), but in no case is the time between receipt of new fuel and conducting the tests to exceed 31 days. The tests, limits, and applicable ASTM Standards are as follows: a. Sample the new fuel oil in accordance with ASTM D4057, b. Verify in accordance with the tests specified in ASTM D975 that the sample has an absolute specific gravity at 60/60'F of > 0.83 and < 0.89, or an API gravity at 60'F of >270 and < 39' when tested in accordance with ASTM D1298, a kinematic viscosity at 400C of> 1.9 centistokes and < 4.1 centistokes, and a flash point > 125&deg;F, and c.
