St. Lucie Units I and 2 Docket Nos. 50-335 and 50-389 L-2003-217 Attachment I Page 2 EVALUATION OF PROPOSED TS CHANGES BACKGROUND Pursuant to 10 CFR 50.90, Florida Power and Light Company (FPL) requests to amend Facility Operating Licenses DPR-67 for St. Lucie Unit 1 and NPF-16 for St. Lucie Unit 2 by incorporating the attached Technical Specification (TS) revisions. The proposed amendments would relocate specific pressure and flow values associated with the high pressure safety injection (HPSI), low pressure safety injection (LPSI), boric acid makeup (BAM), and containment spray (CS) pumps from the TSs to the St. Lucie Units 1 and 2 Updated Final Safety Analysis Reports (UFSARs). Relocation of the specific criteria to the St. Lucie Units 1 and 2 UFSARs would afford FPL operational flexibility to revise the criteria without need for requesting an amendment to the operating license. All changes to the St. Lucie Units I and 2 UFSARs require evaluation pursuant to the 10 CFR 50.59 process.
Precedent Licensing Actions Seabrook Station received a similar license amendment in May 2002 to relocate Technical Specification surveillance requirements for pumps to another licensee-controlled document
[Reference 5].

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2003-217 Attachment I Page 4 Unit 2 TS SR 4.5.2.i is to be completely deleted from the TS (there is no corresponding TS SR for St. Lucie Unit 1).
The TS changes delete the specific testing requirements for the subject pumps and will relocate the requirements to the St. Lucie Units I and 2 UFSARs. This action is consistent with the intent of the 1993 NRC Policy Statement, and is also consistent with revision 2 of NUREG-1432 (STS for CE Plants).
BASIS/JUSTIFICATION FOR PROPOSED CHANGE In July 1993, the NRC issued a Final Policy Statement on Technical Specification Improvements for Nuclear Power Reactors in the Federal Register [Reference 1]. The policy statement contained four objective criteria, whose purpose was to focus the Technical Specifications on only those requirements that are important to operational safety. The four criteria are now codified in 10 CFR 50.36 [Reference 2]. The criteria identify requirements derived from the analyses and evaluations included in the UFSAR that are of immediate concern to the health and safety of the public. Generally, the criteria identify operating requirements related to: 1) detecting reactor coolant pressure boundary degradation; 2) operation within the initial conditions of the accident analyses; 3) accident mitigation; and 4) the operation of other risk-significant structures, systems, or components not covered by the first three criteria. 10 CFR 50.36(c)(2)(ii) requires that a technical specification limiting condition for operation (LCO) must be established for items meeting one or more of the criteria.
The Final Policy Statement also encouraged licensees to implement a voluntary update program of their Technical Specifications to be consistent with the Standard Technical Specifications (i.e.,
NUREG-1432 for Combustion Engineering (CE) plants [Reference 3]). The four 10 CFR 50.36 criteria provide a basis for relocating requirements from the Technical Specifications to other licensee-controlled documents, provided the requirements meet none of the four criteria. NRC Staff Review of NSSS Vendor Groups' Application of the Commission's Interim Policy Statement Criteria to Standard Technical Specifications ("split report") [Reference 4] provides NRC staff review of each reactor vendor Owners Group's application of the four criteria to their respective Standard Technical Specifications (STS). The list of retained and relocated LCOs is tabulated in Appendix C of Reference 4.
The subject TS SRs currently provide details describing pump acceptance criteria and test methods (e.g., testing on recirculation flow) associated with performance surveillance testing of centrifugal pumps. It is proposed that these details be relocated to the UFSAR. These details are not necessary to ensure operability. The requirements of the applicable Limiting Condition for Operation (LCO) and the associated Surveillance Requirements for these systems, as well as the TS definition of OPERABILITY, are adequate to ensure the systems are maintained operable.
As a result, these details are not necessary to ensure the systems can perform their intended safety function and are not required to be in the TS to provide adequate protection of the public health and safety. BAM pumps are not specifically addressed in NUREG-1432, Revision 2.
However, relocating the BAM pump surveillance requirement success criteria and testing methods to the UFSAR meets the intent of the ISTS treatment of other emergency core and containment heat removal centrifugal pumps.
St. Lucie Units I and 2 Docket Nos. 50-335 and 50-389 L-2003-217 Attachment I Page 5 The relocation of these surveillance details for the CS, LPSI, HPSI, and BAM pumps to the St.
Lucie UFSARs maintains the consistency with NUREG-1432. Any change to these details will be made in accordance with 10 CFR 50.59.
Current Unit 2 TS SR 4.5.2.i requires the performance of a flow balance test to the emergency core cooling system (ECCS) subsystems following the completion of modifications that alter the subsystem flow characteristics. Plant procedures governing the restoration of equipment after maintenance specify the appropriate post maintenance testing. It is proposed that this requirement be relocated to the UFSAR. Any time the operability of a system or component has been affected by repair, maintenance, or replacement of a component, post maintenance testing is required to demonstrate operability of the system or component. As such, the requirement to perform a flow balance test after modifications that alter flow characteristics is not required to be in the TS to provide adequate protection of the public health and safety. The TS SR Bases will be revised to state that the flow balancing criteria are contained in the UFSAR to ensure that post modification testing criteria continues to verify the safety analysis assumptions. The relocation of this requirement maintains the consistency with NUREG-1432. Any change to this requirement will be made in accordance with 10 CFR 50.59.
These proposed changes relocate requirements that are not of controlling importance to operational safety. This is consistent with the Improved Standard Technical Specifications for CE plants and the 1993 NRC Policy Statement. The specific pump surveillance verification criteria currently within the TSs may be removed from TSs because they do not meet the four specific criteria in 10 CFR 50.36. Specifically:
Pump performance verification criteria is not considered installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary. Thus, the specific pump performance verification criteria do not satisfy Criterion I (as amended in 10 CFR 50.36) for retention; Pump performance verification criteria is not a process variable that is an initial condition of a design basis accident (DBA) or transient analysis that assumes either the failure of or presents a challenge to the integrity of a fission product barrier. Therefore, the specific pump performance verification criteria do not satisfy Criterion 2 (as amended in 10 CFR 50.36) for retention; Pump performance verification criteria is not a structure, system, or component (SSC) that is part of the primary success path and which functions or actuates to mitigate a DBA or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. Therefore, the specific pump performance verification criteria do not satisfy Criterion 3 (as amended in 10 CFR 50.36) for retention; Pump performance verification criteria is not considered as a significant risk contributor.
Therefore, the specific pump performance verification criteria do not satisfy Criterion 4 (as amended in 10 CFR 50.36) for retention in the Technical Specifications.
Though it is recognized that proper engineered safety feature (ESF) pump performance is necessary to ensure the safety analysis assumptions remain valid, the specific values for determining proper ESF pump performance need not be contained within the TS SR itself. The
St. Lucie Units I and 2 Docket Nos. 50-335 and 50-389 L-2003-217 Attachment I Page 6 specific details controlled by the subject specifications do not need to be included within the scope of the Technical Specifications. The subject details will be adequately controlled in the St.
Lucie UFSARs. The inclusion of the subject details in TSs is not specifically required by 10 CFR 50.36, or other regulations. Additionally, the activities controlled by the subject specification do not pose a threat to the public health and safety. Therefore, the proposed changes to the subject TS SR do not affect plant safety.
SUMMARY
CONCLUSION The TS SRs reviewed above do not meet any of the four 10 CFR 50.36 screening criteria and may be relocated to the respective unit's UFSAR. Relocating these technical specification requirements to the UFSAR will be consistent with the Improved Standard Technical Specifications for CE plants, will be consistent with the 1993 NRC Policy Statement regarding Technical Specifications content, and will ensure future changes are controlled under the requirements of 10 CFR 50.59.

St. Lucie Units I and 2 Docket Nos. 50-335 and 50-389 L-2003-217 Attachment 2 Page 2 DETERMINATION OF NO SIGNIFICANT HAZARDS CONSIDERATION Description of amendment request: Pursuant to 10 CFR 50.90, Florida Power and Light Company (FPL) requests to amend Facility Operating Licenses DPR-67 for St. Lucie Unit 1 and NPF-16 for St. Lucie Unit 2 by incorporating the attached Technical Specification (TS) revisions. The proposed amendments would relocate specific pressure and flow values associated with the high pressure safety injection (HPSI), low pressure safety injection (LPSI),
boric acid makeup (BAM), and containment spray (CS) pumps from the TSs to the St. Lucie Units I and 2 Updated Final Safety Analysis Reports (UFSARs). Relocation of the specific criteria to the St. Lucie Unit 1 and 2 UFSARs would afford FPL operational flexibility to revise the criteria without need for requesting an amendment to the operating license. All changes to the St. Lucie Units I and 2 UFSARs require an evaluation pursuant to 10 CFR 50.59 prior to implementation. Relocation of these requirements to the St. Lucie Units I and 2 UFSARs is consistent with the NRC Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors, FR, 58, No. 139, page 39132, dated July 22, 1993, and is also consistent with 10 CFR 50.36 and Revision 2 of NUREG-1432, Standard Technical Specifications for CE Plants.
Pursuant to 10 CFR 50.92, a determination may be made that a proposed license amendment involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not: (1) involve a significant increase in the probability or consequences of an accident previously evaluated; (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety. Each standard is discussed as follows.
- 1) Would operation of the facility in accordance with the proposed amendments involve a significant increase in the probability or consequences of an accident previously evaluated?
The proposed changes to relocate the BAM, CS, HPSI, and LPSI pump surveillance verification details in the aforementioned Technical Specifications surveillance requirements to the St. Lucie UFSARs do not adversely affect accident initiators or precursors nor alter the design assumptions, conditions, configuration of the facility, or the manner in which it is operated. The proposed changes do not alter or prevent the ability of structures, systems, or components to perform their intended function to mitigate the consequences of an initiating event within the acceptance limits assumed in the St. Lucie UFSARs.
The subject surveillance requirement criteria relocated to the St. Lucie UFSARs will continue to be administratively controlled. Changes to the St. Lucie UFSARs are evaluated and controlled under 10 CFR 50.59 prior to implementation. Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
St. Lucie Units I and 2 Docket Nos. 50-335 and 50-389 L-2003-217 Attachment 2 Page 3
- 2)
Would operation of the facility in accordance with the proposed amendments create the possibility of a new or different kind of accident from any accident previously evaluated?
The proposed changes do not alter the design assumptions, conditions, or configuration of the facility or the manner in which the plant is operated. There are no changes to the source term or radiological release assumptions used in evaluating the radiological consequences in the St. Lucie UFSARs. The proposed changes have no adverse impact on component or system interactions. The proposed changes vill not adversely degrade the ability of systems, structures and components important to safety to perform their safety function nor change the response of any system, structure or component important to safety as described in the UFSARs. The proposed changes do not change the level of programmatic and procedural details of assuring operation of the facility in a safe manner. Since there are no changes to the design assumptions, conditions, configuration of the facility, or the manner in which the plant is operated and surveilled, the proposed changes do not create the possibility of a new or different kind of accident from any previously analyzed.
- 3)
Would operation of the facility in accordance with the proposed amendments involve a significant reduction in a margin of safety?
There is no adverse impact on equipment design or operation and there are no changes being made to the Technical Specification required safety limits or safety system settings that would adversely affect plant safety. The proposed changes do not reduce the level of programmatic or procedural controls associated with the activities presently performed via the aforementioned surveillance requirements.
Future changes to the relocated technical requirements will require an evaluation pursuant to the provisions of 10 CFR 50.59 prior to implementation.
Therefore, relocation of the specific pump pressure and flow criteria contained in the aforementioned Technical Specifications Surveillance Requirements to the St. Lucie Units 1 and 2 UFSARs does not involve a significant reduction in the margin of safety provided in the existing specifications.
Based on the determination made above, FPL concludes that the proposed amendments involve no significant hazards consideration.
Environmental Consideration The proposed license amendments do not change requirements with respect to the use of a facility component located within the restricted area as defined in 10 CFR Part 20. The proposed amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite, and no significant increase in individual or cumulative occupational radiation exposure. FPL concluded that the proposed amendments involve no significant hazards consideration and meet the criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and that, pursuant to 10 CFR 51.22(b), an environmental impact
St. Lucie Units I and 2 Docket Nos. 50-335 and 50-389 L-2003-217 Attachment 2 Page 4 statement or environmental assessment need not be prepared in connection with issuance of the amendments.
Conclusion FPL concludes, 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.

Temperature changes In the RCS Impose reactivity changes by means of the moderator temperature coefficient. Plant temperature changes are allowed provided the temperature change Is accounted for In the calculated SDM. Small changes In RCS temperature are unavoidable and so long as the required SDM Is maintained during these changes, any positive reactivity additions will be limited to acceptable levels.
Introduction of temperature changes must be evaluated to ensure they do not result In a loss of required SDM.
The boron addition capability after the plant has been placed In MODES 5 and 6 requires either 3650 gallons of 2.5 to 3.5 weight percent boric acid solution (4371 to 6119 ppm boron) from the boric acid tanks or 11,900 gallons of 1720 ppm borated water from the refueling water tank to makeup for contraction of the primary coolant that could occur if the temperature Is lowered from 2000F to 140 0F.
The restrictions associated with the establishing of the flow path from the RWT to the RCS via a single HPSI pump provide assurance that 10 CFR 50 Appendix G pressure/temperature limits will not be exceeded in the case of any Inadvertent pressure transient due to a mass addition to the RCS. If RCS pressure boundary Integrity does not exist as defined In Specification 1.16, these restrictions are not required. Additionally, a limit on the maximum number of operable HPSI pumps Is not necessary when the pressurizer manway cover or the reactor vessel head Is removed.

Introduction of temperature changes must be evaluated to ensure they do not result In a loss of required SDM.
The boron capability required below 2000F Is based upon providing a SHUTDOWN MARGIN corresponding to its COLR limit after xenon decay and cooldown from 200OF to 1400F. This condition requires either 6750 gallons of 1720 ppm - 2100 ppm borated water from the refueling water tank or 3550 gallons of 2.5 to 3.5 weight percent boric acid solution from the boric acid makeup tanks.
The contained water volume limits Includes allowance for water not available because of discharge line location and other physical characteristics.
The OPERABILITY of one boron Injection system during REFUELING ensures that this system is available for reactivity control while In MODE 6.
The limits on contained water volume and boron concentration of the RWT also ensure a pH value of between 7.0 and 8.0 for the solution recirculated within containment after a LOCA. This pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic stress corrosion on mechanical systems and components.

Either subsystem operating In conjunction with the safety injection tanks Is capable of supplying sufficient core cooling to limit the peak cladding temperatures within acceptable limits for all postulated break sizes ranging from the double ended break of the largest RCS cold leg pipe downward. In addition, each ECCS subsystem provides long term core cooling capability In the recirculation mode during the accident recovery period.
TS 3.5.2. ACTION a.1. provides an allowed outagelaction completion time (AOT) of up to 7 days from Initial discovery of failure to meet the LCO provided the affected ECCS subsystem Is Inoperable only because its associated IPSI train Is inoperable. This 7 day AOT Is based on the findings of a deterministic and probabilistic safety analysis and Is referred to as a risk-informed' AOT extension. 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 (ADM-17.08) that implements the Maintenance Rule pursuant to 10 CFR 50.65.
The Surveillance Requirements provided to ensure OPERABILITY of each component ensure that at a minimum, the assumptions used in the accident analyses are met and that subsystem OPERABILITY is maintained.
The limitations on HPSI pump operability when the RCS temperature Is
< 270OF and < 2360F, and the associated Surveillance Requirements provide additional administrative assurance that the pressure/temperature limits (Figures 3.4-2a and 3.4-2b) will not be exceeded during a mass addition transient mitigated by a single PORV. A limit on the maximum number of operable HPSI pumps Is not necessary when the pressurizer manway cover or the reactor vessel head Is removed.

The requirement for one high pressure safety injection pump to be rendered Inoperable prior to entering MODE 5, although the analysis supports actuation of safety Injection in a water solid RCS with pressurizer heaters energized, provides additional administrative assurance that a mass addition pressure transient can be relieved by the operation of a single PORV or SDCRV.

Maintenance of proper flow resistance and pressure drop in the piping system to each Injection point Is necessary to: (1) prevent total pump flow~ from exceeding runout conditions when the system is in Its minimum resistance configuration, (2) provide the proper flow split between Injection points In accordance with the assumptions used In the ECCS-LOCA analyses, and (3) provide an acceptable level of total ECCS flow to all injection points equal to or above that assumed In the ECCS-LOCA analyses. The requirement to dissolve a representative sample of TSP In a sample of RWT water provides assurance that the stored TSP will dissolve In borated water at the postulated post-LOCA temperatures.

During a Design Basis Accident (DBA), at least two containment cooling trains or two containment spray trains, or one of each, is capable of maintaining the peak pressure and temperature within design limits. One containment spray train has the capability, In conjunction with the Spray Additive System, to remove iodine from the containment atmosphere and maintain concentrations below those assumed In the safety analyses.

BASES (continued) 3/4.6.2 DEPRESSURIZATION AND COOLING SYSTEMS 3/4.6.2.1 CONTAINMENT SPRAY AND COOLING SYSTEMS The OPERABILITY of the containment spray and cooling systems ensures that depressurization and cooling capability will be available to limit post-accident pressure and temperature In the containment to acceptable values. During a Design Basis Accident (DBA), at least two containment cooling trains or two containment spray trains, or one of each, Is capable of maintaining the peak pressure and temperature within design limits. One containment spray train has the capability, In conjunction with the Iodine Removal System, to remove Iodine from the containment atmosphere and maintain concentrations below those assumed In the safety analyses. To ensure that these conditions can be met considering single-failure criteria, two spray trains and two cooling trains must be OPERABLE.

The 10 day constraint for ACTIONS 1.a and 1.b Is based on coincident entry Into two ACTION conditions (specified In ACTION 1.c) coupled with the low probability of an accident occurring during this time. If the system(s) cannot be restored to OPERABLE status within the specified completion time, alternate actions are designed to bring the unit to a mode for which the LCO does not apply.

Insert 2 Periodic surveillance testing of ECCS pumps to detect gross degradation caused by impeller structural damage or other hydraulic component problems is required by Section XI of the ASME Code. This type of testing may be accomplished by measuring the pump developed head at only one point of the pump characteristic curve. This verifies both that the measured performance is within an acceptable tolerance of the original pump baseline performance and that the performance at the test flow is greater than or equal to the performance assumed in the unit safety analysis. Surveillance Requirements are specified in the Inservice Testing Program, which encompassesSection XI of the ASME Code.Section XI of the ASME Code provides the activities and frequencies necessary to satisfy the requirements.
