1.0 DESCRIPTION

The proposed amendment would modify Technical Specifications (TS) to risk-inform requirements regarding selected Required Action End States. The changes are consistent with Nuclear Regulatory Commission (NRC)-approved Technical Specification Task Force (TSTF) traveler TSTF-422, Revision 2, "Change in Technical Specifications End States (CE NPSD-1186)," dated December 22, 2009 (ADAMS Accession Number ML093570241) (Reference 1).

The FederalRegister notice published on April 7, 2011 (76 FR 19510) (Reference 2), announced the availability of this TS improvement as part of the consolidated line item improvement process (CLIIP).

2.0 ASSESSMENT 2.1 Applicability of Topical Report, TSTF-422, and Model Safety Evaluation Florida Power & Light Company (FPL) has reviewed Combustion Engineering (CE) Topical Report (TR) NPSD-1 186 (Reference 3), TSTF-422, Revision 2, and the NRC staff's model safety evaluation (SE) (Reference 4) as part of the CLIIP. FPL has concluded that the information in TR NPSD-1 186, TSTF-422, Revision 2, and the NRC staff's model SE are applicable to St. Lucie Unit 1 and St. Lucie Unit 2 and justify this license amendment request (LAR) for incorporation of the changes to the St. Lucie Unit 1 and St. Lucie Unit 2 TS.

2.2 Optional Changes and Variations FPL is proposing variations or deviations from TR NPSD-1 186, TSTF-422, Revision 2, and the NRC staff's model SE referenced in the FederalRegister on April 7, 2011 (76 FR 19510), as part of the CLIIP Notice of Availability.

FPL has reviewed TSTF-422, Revision 2, and the model SE referenced in the Federal Register Notice of Availability published on April 7, 2011 (76 FR 19510), as part of the CLIIP. The model SE refers to Regulatory Guide (RG) 1.182, "Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants," and to the guidance in Revision 2 of NUMARC 93-0 1. St. Lucie Unit 1 and St. Lucie Unit 2 are taking a deviation from the model SE because RG 1.182 has been withdrawn since it was redundant due to the inclusion of its subject matter in Revision 3 of RG 1.160, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," dated May 2012. RG 1.160 endorsed Revision 4A of NUMARC 93-01, "Industry Guidance for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants,"

dated April 2011. Topical Report CE NPSD-1 186-A, "Technical Justification for the Risk Informed Modification to Selected Required Action End States for CEOG Member PWRs,"

St. Lucie Units 1 and 2 L-2015-182 Docket Nos. 50-335 and 50-389 Attachment 1 License Amendment Request Page 2 of 7 references RG 1.182 with regard to its endorsement of NUMARC 93-01. Both Revision 2 and 3 of NUMARC 93-01 are mentioned in CE NPSD-1 186-A. The FPL review concluded verification of compliance with Section 11 of NUMNARC 93-0 1, Nuclear Management and Resource Council, Revision 4A, April 2011, as well as the supporting WCAP-16364-NP, Revision 2, "Implementation Guidance for Risk Informed Modification to Selected Required Action End States at Combustion Engineering NSSS Plants (TSTF-422)," dated May 2010. FPL fleet procedure EN-AA-1 00-2002, "Maintenance Rule Program Administration," references RG 1.160 and NUMARC 93-01 as the governing guidance for determination of the risk significance of structures, systems and components within the scope of the Maintenance Rule. Application of RG 1.160, Revision 3, and NUJMARC 93-01, Revision 4A, does not result in inconsistencies with the intent of CE NPSD-1 186-A, WCAP-16364-NP, Revision 2, TSTF-422, Revision 2, and the model SE.

Because the St. Lucie Unit 1 and St. Lucie Unit 2 TS have not been converted to the standard TS (STS) ofNUREG-1432, "Standard Technical Specifications - Combustion Engineering Plants,"

(on which TSTF-422, Revision 2 is based), the layout of the TS when compared to TSTF-422, Revision 2 may differ significantly in format; however, the technical differences are minor. In addition, St. Lucie Unit 1 and St. Lucie Unit 2 are "analog" plants; therefore, only "analog" instrumentation STS are applicable. Additional differences between St. Lucie Unit 1 and St.

Lucie Unit 2 TS and STS are as follows.

1. The STS use terms such as "Required Action" and "Completion Time" where the St.

Lucie Unit 1 and St. Lucie Unit 2 TS use equivalent terms of "Action" and "Allowed Outage Time." While the St. Lucie Unit 1 and St. Lucie Unit 2 terms are maintained in the TS for consistency, the STS and equivalent St. Lucie Unit 1 and St. Lucie Unit 2 TS terms may be used interchangeably throughout this letter. These differences do not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

2. Changes may have required the movement of information from one TS page to another.

This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

3. In general, the St. Lucie Unit 1 and St. Lucie Unit 2 TS use the MODE noun names (i.e.,

"HOT SHUTDOWN" in lieu of "MODE 4"). The use of noun names does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

4. St. Lucie Unit 1 TS 3.3.2.1, Table 3.3-3, ACTION 11 and St. Lucie Unit 2 TS 3.3.2, Table 3.3-3, ACTION 15 currently state that under certain conditions, action must be taken to "exit the mode of applicability." ACTION 11 and ACTION 15 are associated with Engineered Safety Feature Actuation System (ESFAS) Manual Trip and Automatic Actuation Logic. Consistent with TSTF-422, Revision 2, ACTION 11 and ACTION 15 already refer to HOT SHUTDOWN; therefore, only the prohibition from

St. Lucie Units l and 2 L-2015-182 Docket Nos. 50-335 and 50-389 Attachment 1 License Amendment Request Page 3 of 7 using Limiting Condition for Operation (LCO) 3.0.4.a when entering HOT SHUTDOWN is added. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

5. St. Lucie Unit 1 and St. Lucie Unit 2 TS do not contain a separate TS for the Control Room Isolation Signal (CRIS) function (STS 3.3.8). St. Lucie Unit 1 and St. Lucie Unit 2 control rooms are isolated upon receipt of a high radiation signal. The associated radiation monitors are included in St. Lucie Unit 1 TS 3.3.3.1 Table 3.3-6 ACTION 17 and St. Lucie Unit 2 TS 3.3.3.1 Table 3.3-6 ACTION 27. St. Lucie Unit 1 TS 3.3.3.1 Table 3.3-6 ACTION 17 and St. Lucie Unit 2 TS 3.3.3.1 Table 3.3-6 ACTION 27 have been modified consistent with TSTF-422, Revision 2. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

6. St. Lucie Unit 1 and St. Lucie Unit 2 TS do not have a Chemical and Volume Control System (CVCS) Isolation Signal TS (STS 3.3.9), which isolate separate letdown isolation valves in response to a high pressure condition. Therefore, no TSTF-422, Revision 2 changes related to CVCS are incorporated into the St. Lucie Unit 1 and St. Lucie Unit 2 TS. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

7. St. Lucie Unit 1 and St. Lucie Unit 2 TS do not have a Shield Building Filtration Actuation Signal (SBFAS) TS (STS 3.3.10). Therefore, no TSTF-422, Revision 2 changes related to CVCS are incorporated into the St. Lucie Unit 1 and St. Lucie Unit 2 TS. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

8. St. Lucie Unit 1 and St. Lucie Unit 2 TS do not contain a separate ACTION for not meeting Refueling Water Tank (RWT) boron concentration and/or temperature limits.

Adopting these ACTIONs is beyond the scope of TSTF-422, Revision 2. Because the TSTF-422, Revision 2 changes are related only to these ACTIONs, no TSTF-422, Revision 2 related changes are adopted for St. Lucie Unit 1 and St. Lucie Unit 2 TS 3.5.4, "Refueling Water Tank." This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

9. STS 3.6.6.A, "Containment Spray and Cooling Systems (Atmospheric and Dual) contains requirements for MODES 1, 2, 3, and 4. St. Lucie Unit 1 and St. Lucie Unit 2 TS 3.6.2.1 contains requirements for containment spray trains and containment cooling trains in MODES 1, 2, and 3 with pressurizer pressure > 1750 psia and separate requirements for containment spray trains and containment cooling trains in MODE 3 with pressurizer pressure < 1750 psia. The TSTF-422, Revision 2 ACTIONs are comparable to the existing St. Lucie Unit 1 and St. Lucie Unit 2 ACTIONs.

Furthermore, the TSTF-422, Revision 2 prohibition from using LCO 3.0.4.a when entering HOT SHUTDOWN is not required because HOT SHUTDOWN (MODE 4) is

St. Lucie Units 1 and 2 L-2015-182 Docket Nos. 50-3 35 and 50-3 89 Attachment 1 License Amendment Request Page 4 of 7 not a St. Lucie Unit 1 or St. Lucie Unit 2 Mode of Applicability. As a result, the TSTF-422, Revision 2 changes were not adopted for St. Lucie Unit 1 and St. Lucie Unit 2 TS 3.6.2.1. This deviation does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

10. St. Lucie Unit 1 and St. Lucie Unit 2 Ultimate Heat Sink design does not use cooling towers; therefore, TSTF-422, Revision 2 changes to Ultimate Heat Sink (STS 3.7.9) are not applicable to St. Lucie Unit 1 and St. Lucie Unit 2 TS. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

11. St. Lucie Unit 1 and St. Lucie Unit 2 designs do not have an Essential Chilled Water (ESW) System. Therefore, TSTF-422, Revision 2 changes to STS 3.7.10 are not applicable to St. Lucie Unit 1 and St. Lucie Unit 2 TS. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

12. The Control Room Emergency Air Cleanup System (CREACS) (STS 3.7.11) and the Control Room Emergency Air Temperature Control System (CREATCS) (STS 3.7.12) requirements are contained in a single TS 3.7.7.1 for St. Lucie Unit 1 and a single TS 3.7.7 for St. Lucie Unit 2. Therefore, the TSTF-422, Revision 2 related changes are incorporated into the single St. Lucie Unit 1 TS and single St. Lucie Unit 2 TS. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

13. St. Lucie Unit 1 and St. Lucie Unit 2 do not have TS requirements associated with a Penetration Room Exhaust Air Cleanup System (STS 3.7.15). Therefore, TSTF-422, Revision 2 changes to STS 3.7.15 are not applicable to St. Lucie Unit 1 and St. Lucie Unit 2 TS. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

14. St. Lucie Unit 2 TS 3/4.8.3, "Onsite Power Distribution Operating," contains requirements associated with inverters. St. Lucie Unit 1 TS 3/4.8.2, "Onsite Power Distribution Systems A.C. Distribution - Operating," does not contain requirements associated with inverters. Therefore, TSTF-422, Revision 2 changes to STS 3.8.7 are not applicable to St. Lucie Unit 1ITS and oniy applicable to St. Lucie Unit 2 TS. This difference does not invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

15. Because the St. Lucie Unit 1 and St. Lucie Unit 2 TS have not been converted to the STS version, the associated TS Bases for each TSTF-422, Revision 2 change is modified as necessary to be consistent with both the current St. Lucie Unit 1 and St. Lucie Unit 2 TS Bases and that presented in TSTF-422, Revision 2. This difference does not

St. Lucie Units 1 and 2 L-2015-182 Docket Nos. 50-335 and 50-389 Attachment 1 License Amendment Request Page 5 of 7 invalidate the applicability of TSTF-422, Revision 2 and the model SE to St. Lucie Unit 1 and St. Lucie Unit 2 TS.

3.0 REGULATORY ANALYSIS

3.1 No Significant Hazards Consideration Determination Florida Power & Light Company (FPL) has evaluated the proposed changes to the TS using the criteria in 10 CFR 50.92 and has determined that the proposed changes do not involve a significant hazards consideration.

Description of Amendment Request: A change is proposed to the TS of St. Lucie Unit 1 and St.

Lucie Unit 2, consistent with TSTF-422, Revision 2, to allow, for some systems, entry into hot shutdown rather than cold shutdown to repair equipment, if risk is assessed and managed consistent with the program in place for complying with the requirements of 10 CFR 50.65(a)(4).

Changes proposed in TSTF-422 will be made to the St. Lucie Unit 1 and St. Lucie Unit 2 TS for selected Required Action end states providing this allowance.

Basis for no significant hazards consideration determination: As required by 10 CFR 50.9 1(a),

FPL analysis of the issue of no significant hazards consideration is presented below:

1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

The proposed change allows a change to certain required end states when the Technical Specification (TS) Completion Times (CTs) for remaining in power operation are exceeded. Most of the requested TS changes are to permit an end state of hot shutdown (Mode 4) rather than an end state of cold shutdown (Mode 5) contained in the current TS.

The request was limited to: (1) those end states where entry into the shutdown mode is for a short interval, (2) entry is initiated by inoperability of a single train of equipment or a restriction on a plant operational parameter, unless otherwise stated in the applicable TS, and (3) the primary purpose is to correct the initiating condition and return to power operation a soon as is practical. Risk insights from both the qualitative and quantitative risk assessments were used in specific TS assessments. Such assessments are documented in Section 5.5 of CE NIPSD-1 186, Rev 0, "Technical Justification for the Risk-Informed Modification to Selected Required Action End States for CEOG Member PWRs." They provide an integrated discussion of deterministic and probabilistic issues, focusing on specific TSs, which are used to support the proposed TS end state and associated restrictions. Therefore, the probability of an accident previously evaluated is not significantly increased, if at all. The consequences of an accident after adopting proposed TSTF-422 are no different than the consequences of an accident prior to adopting TSTF-422. Therefore, the consequences of an accident previously evaluated are

St. Lucie Units 1 and 2 L-2015-182 Docket Nos. 50-335 and 50-389 Attachment 1 License Amendment Request Page 6 of 7 not significantly affected by this change. The addition of a requirement to assess and manage the risk introduced by this change will further minimize possible concerns.

Therefore, this change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No.

The proposed change does not involve a physical alteration of the plant (no new or different type of equipment will be installed). Allowing a change to certain required end states when the TS CTs for remaining in power operation are exceeded, i.e., entry into hot shutdown rather than cold shutdown to repair equipment, if risk is assessed and managed, will not introduce new, failure modes or effects and will not, in the absence of other unrelated failures, lead to an accident whose consequences exceed the consequences of accidents previously evaluated. The addition of a requirement to assess and manage the risk introduced by this change and the commitment by the licensee to adhere to the guidance in WCAP-16364-NP, Revision 2, "Implementation Guidance for Risk Informed Modification to Selected Required Action End States at Combustion Engineering NSSS Plants (TSTF-422)," will further minimize possible concerns.

Therefore, this change does not create the possibility of a new or different kind of accident from an accident previously evaluated.

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No.

The proposed change allows, for some systems, entry into hot shutdown rather than cold shutdown to repair equipment, if risk is assessed and managed. The CEOG's risk assessment approach is comprehensive and follows NRC staff guidance as documented in Regulatory Guides (RGs) 1.174 and 1.177. In addition, the analyses show that the criteria of the three-tiered approach for allowing TS changes are met. The risk impact of the proposed TS changes was assessed following the three-tiered approach recommended in RG 1.177. A risk assessment was performed to justify the proposed TS changes. The net change to the margin of safety is insignificant.

Therefore, this change does not involve a significant reduction in a margin of safety.

Based upon the reasoning presented above, FPL concludes that the requested change involves no significant hazards consideration, as set forth in 10 CFR 50.92(c), "Issuance of Amendment."

St. Lucie Units 1 and 2 L-2015-182 Docket Nos. 50-335 and 50-389 Attachment 1 License Amendment Request Page 7 of 7 3.2 Verification, Commitments, and Additional Information Needed FPL commits to the regulatory commitments in Attachment 2. In addition, FPL has proposed TS Bases consistent with TSTF-422, Revision 2, which provides guidance and details on how to implement the new requirements. Implementation of TSTF-422 requires that risk be managed and assessed, and the configuration risk management program is adequate to satisfy this requirement. The risk assessment need not be quantified, but may be a qualitative assessment of the vulnerability of systems and components when one or more systems are not able to perform their associated function. Finally, FPL has a Bases Control Program consistent with Section 5.5 of the Standard TSs (STS).

4.0 ENVIRONMENTAL CONSIDERATION

The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR Part 20, and would change an inspection or surveillance requirement. However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51 .22(c)(9).

Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

Response time may be demonstrated by any series of sequential, overlapping or total channel measurements, including allocated sensor response time, provided that suczh tests demonstrate total channel response time as defined.

CEOG Topical Report CE.NPSD-1167, and FPL No Significant Hazards Evaluation PSL-ENG-SEIS-03-043 provide the basis and methodology for using allocated sensor response times in the overall verification of the channel response time for specific sensors identified in these documents. The allocated sensor response time must be verified prior to placing a new component in operation and re-verified after maintenance that may adversely affect the sensor response time (e.g., replacement of a transmitter DP cell or variable damping circuits). Sensor response time verification may be demonstrated by either 1) in place, onsite or offsite test measurements or

2) utilizing replacement sensors with certified response times.

The CEOG topical report and FPL evaluation only cover certain sensor model numbers. If sensors are replaced with types not previously evaluated, then periodic response time testing (RTT) for the new sensor must. either be performed and the appropriate changes made to plant procedures, or an additional request for RTT elimination must be submitted and approved by the NRC, If, however, the replacement sensor is one for.which RTT elimination has been approved, then FPL may modify the plant procedures, using an allocated response time based upon a vendor-supplied response time value, or upon statistical analysis of historical data for that transmitter type and model.

The Safety Injection Actuation Signal (SIAS) provides direct actuation, of the Containment Isolation Signal (018) to ensure containment isolation in the event of a small break LOCA.

LUCIE UNIT I BASES FOR SECTION 314.4 314.4 REACTOR COOLANT SYSTEM BASES 3/4.4.1 REACTOR COOLANT LOOPS AND COOLANT CIRCULATION i The plant is designed to operate with both reactor coolant loops and associated reactor coolant pumps in operation, and maintain DNBR above the DNBR limit during all normal operations and anticipated transients. In MODES 1 and 2 with one reactor coolant loop not in operation, this specification requires that the plant be in at least HOT STANDBY within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months .

In MODE 3, a single reactor coolant loop provides sufficient heat removal capability for removing decay heat; however, single failure considerations require that two loops be OPERABLE.

In MODE 4, and in MODE 5 with reactor coolant loops filled, a single reactor coolant loop or shutdown cooling loop provides sufficient heat removal capability for removing decay heat; but single failure considerations require that at least two loops (either shutdown cooling or RCS) be OPERABLE, In MODE 5 with reactor coolant loops not filled, a single shutdown cooling loop provides sufficient heat removal capability for removing decay heat; but single failure considerations and the unavailability of the steam generators as a heat removing component, require that at least two shutdown cooling loops be OPERABLE.

The operation of one Reactor Coolant Pump or one shutdown cooling pump provides adequate flow to ensure mixing, prevent stratification and produce gradual reactivity changes during boron concentration reductions in the Reactor Coolant System. The reactivity change rate associated with boron reductions will, therefore, be within the capability of operator recognition and control.

If no coolant loops are in operation during shutdown operations, suspending the introduction of coolant into the RCS with boron concentration less than required to meet the minimum SDM of LCO 3.1.1.1 or 3.1.1.2 is required to assure continued safe operation.

Introduction of coolant inventory must be from sources that have a boron concentration greater than what would be required in the RCS for minimum 5DM or refueling boron concentration. This may result in an overall reduction in RCS boron concentration, but provides acceptable margin to maintaining subcritical operation.

St. Lucie Units 1 and 2 L-2015-182 Docket Nos. 50-335 and 50-389 Attachment 3 License Amendment Request Page 24 of 42 INS ERT 5 If only one required shutdown cooling train is OPERABLE and in operation and no required RCS loops are OPERABLE, redundancy for heat removal is lost and the plant must be placed in a configuration that minimizes overall plant risk. Thiis redundancy is obtained bY making at least one steam generator available for decay heat removal via natural circulation because:

1.. MODE 4 operation poses overall lower risk of core damage and large early radiation release than does MODE 5 (reference CE NPSD-1 186-A, Technical Justification for the FI~sk Informed Modification to Selected Required Action End States for CEOG PWRs, October 2001). This is particularly true with shutdown cooling impaired.

2. In MODE 4, RCS and steam generator conditions may be maintained such that failure of the operating shutdown cooling train may be mitigated by natural circulation heat removal through one or more steam generators.

Remaining within the Applicability of the LCO is acceptable because the plant risk in MODE 4 is similar to or lower than MODE 5 (reference CE NPSD-1 186-A, Technical Justification for the Risk Informed Modification to Selected Required Action End States for CEOG PWRs, October 2001). However, voluntary entry into MODE 5 may be made as it is also an acceptable low-risk state.

This restriction, in conjunction with the leakage rate limitation, will limit the site boundary radiation doses to within the limits of 10 CFR Part 100 during accident conditions.

In accordance with Generic Letter 91-08, "Removal of Component Lists from Technical Specifications," the opening of locked or sealed closed containment isolation valves on an intermittent basis under administrative control includes the following considerations: (1) stationing an operator, who is in constant communication with the control room, at the valve controls, (2) instructing this operator to close these valves in an accident situation, and (3) assuring that environmental conditions will not preclude access to close the valves and this action will prevent the release of radioactivity outside the containment.

r314.6.1.2 CONTAINMENT LEAKAGE The limitations on containment leakage rates ensure that total containment leakage volume will not exceed the value assumed in the accident analyses at the peak accident pressure, Pa (42.77 psig) which results from the limiting design basis loss of coolant accident.

The surveillance testing for measuring leakage rates is performed in accordance with the Containment Leakage Rate Testing Program and is consistent with the requirements of Appendix "J" of 10 CFR 50, Option B and Regulatory Guide 1.163 Rev. 0, as modified by approved exemptions.

3t4.6.1.3 CONTAINMENT AIR LOCKS The limitations on closure and leak rate for the containment air locks are required to meet the restrictions on CONTAINMENT INTEGRITY and containment leak rate. Surveillance testing of the air lock seals provides assurance that the overall air lock leakage will not become excessive due to seal damage during the intervals between air lock leakage tests.

Ensuring that the containment :spray pump discharge pressure is met satisfies the periodic surveillance requirement to detect gross degradation caused by impeller structural damage or other hydraulic component problems. Along with this requirement.. Section Xl of the ASME Code verifies the pump developed head at one point on the pump characteristic curve to verify 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 encompasses Section Xl of the ASME Code. Section Xl of the ASME Code provides the activities and frequencies necessary to satisfy the requirements.

314.6.2.2 SPRAY ADDITIVE SYSTEM The OPERABILITY of the spray additive system ensures that sufficient NaOH is added to the containment spray in the event of a LOCA. The limits on NaCH volume and concentration ensure a Containment sump pH value of between 7.0 and 9.66 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. The contained water volume limit includes an allowance for water not usable because of tank discharge line location or other physical characteristics. These assumptions are consistent with the iodine removal efficiency assumed in the accident analyses.

CONTAINMENT ISOLATION VALVES The OPERABILITY of the containment isolation valves ensures that the containment atmosphere will be =isolated from the outside environment in the event of a release of radioactive, material to the containment atmosphere or pressurization of the containment.

TS 3.8.1.1, ACTION "b" provides an allowed outage/action 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" ACT.

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 upon discovery, 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..

Action g prohibits the application of LCO 3.0,4.b to an inoperable diesel generator. There is an increased risk associated with entering a MODE or other specified condition in the Applicability with an inoperable diesel generator and the provisions of LCO 3.0.4.b, which allow entry into a MODE or other specified condition in the Applicability with the LCO not met after performance of a risk assessment addressing inoperable systems and components, should not be applied in this circumstance.

Ambient conditions are the normal standby conditions for the diesel engines. Any normally running warmnup 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.

The measurement of response time at the specified frequencies provides assurance that the protective and ESF action function associated with each channel is completed within the time limit assumed in the safety analyses.

No credit was taken in the analyses for those channels with response times indicated as not applicable.

Response time may be demonstrated by any series of sequential, overlapping or total channel measurements, including allocated sensor response time, provided that such tests demonstrate total channel response time as defined.

CEOG Topical Report CE NPSD-1 167, and FPL No Significant Hazards Evaluation PSL-ENG-SEIS-03-043 provide the basis and methodology for using allocated sensor response times in the overall verification of the channel response time for specific sensors identified in these documents.

The allocated sensor response time must be verified prior to placing a new component in operation and re-verified after maintenance that may adversely affect the sensor response time (e.g., replacement of a transmitter DP cell or variable damping circuits). Sensor response time verification may be demonstrated by either 1) in place, onsite or offsite test measurements or

2) utilizing replacement sensors with certified response times.

The CEOG topical report and FPL evaluation only cover certain sensor model numbers. If sensors are replaced with types not previously evaluated, then periodic response time testing (RTT) for the new sensor must either be performed and the appropriate changes made to plant procedures, or an additional request for RTT elimination must be submitted and approved by the NRC. lf, however, the replacement sensor is one for which RTT elimination has been approved, then FPL may modify the plant procedures, using an allocated response time based upon a vendor-supplied response time value, or upon statistical analysis of historical data for that transmitter type and model.

The Safety Injection Actuation Signal (SIAS) provides direct actuation of the Containment Isolation Signal (CIS) to ensure containment isolation in the event of a small break LOCA.

3/4.3.3 RADIATION MONITORING INSTRUMENTATION The OPERABILITY of the radiation monitoring channels ensures that: (1) the radiation levels are continually measured in the areas served by the individual channels; and (2) the alarm or automatic action is initiated when the radiation level trip setpoint is exceeded; and (3) sufficient information is available on selected plant parameters to monitor and assess these variables following an accident. This capability is consistent with the recommendations of Regulatory Guide 1.97, "Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess Plant and Environs Conditions During and Following an ACcident," December 1980 and NUREG-0737, "Clarification of TMI Action Plan Requirements," November 1980.

Surveillance Requirement 4.3.3.2 ensures that the channel actuation response times are less than the maximum times assumed in the analyses.

Testing of the final actuating devices, which make up the bulk of the response time, is included in the surveillance testing. NSER.T 4 3/4.3.5 REMOTE SHUTDOWN INSTRUMENTATION The OPERABILITY of the remote shutdown instrumentation ensures that sufficient capability is available to permit shutdown and maintenance of HOT STANDBY of the facility from locations outside of the control room.

This capability is requir'ed in the event control room habitability is lost and is consistent with General Design Criteria 19 of 10 CFR 50.

The OPERABILITY of the remote shutdown system instrumentation ensures that a fire will not preclude achieving safe shutdown. The remote shutdown system instrumentation, control circuits, and transfer switches are independent of areas where a fire could damage systems normally used to shut down the reactor. This capability is consistent with General Design Criterion 3 and Appendix R to 10 CFR Part 50.

10 ST. LUCIE UNIT 2 BASES FOR SECTION 314.4 * ..

3/4.4 REACTOR COOLANT SYSTEM BASES 314.4.1 REACTOR COOLANT LOOPS AND COOLANT CIRCULATION The plant is designed to operate with both reactor coolant loops and associated reactor coolant pumps in operation, and maintain DNBR above the DNBR limit during all normal operations and anticipated transients. In MODES 1 and 2 with one reactor coolant loop not in operation, this specification requires that the plant be in at least HOT STANDBY within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months .

In MODE 3, a single reactor coolant ioop provides sufficient heat removal capability for removing decay heat; however, single failure considerations require that two loops be OPERABLE.

In MODE 4, and in MODE 5 with reactor coolant ioops filled, a single reactor coolant loop or shutdown cooling loop provides sufficient heat removal capability for removing decay heat; but single failure considerations require that at least two loops (either shutdown cooling or RCS) be OPERABLE.

In MODE 5 with reactor coolant loops not filled, a single shutdown cooling loop provides sufficient heat removal capability for removing decay heat; :but single failure considerations and the unavailability of the steam generators as a heat removing component, require that at least two shutdown cooling loops be OPERABLE.

The operation of one reactor coolant pump or one shutdown cooling pump provides adequate flow to ensure mixing, prevent stratification and produce.

gradual reactivity changes during boron concentration reductions in the Reactor Coolant System. The reactivity change rate associated with boron reductions will, therefore, be within the capability of operator recognition and control.

If no coolant loops are in operation during shutdown operations, suspending the introduction of coolant into the RCS with boron concentration less than required to meet the minimum SDM of LCO 3,1.1 .1 or 3.1 .1.2 is required to assure continued safe operation. Introduction of coolant inventory must be from sources that have a boron concentration greater than what would be required in the ROS for minimum SDM or refueling boron concentration. This may result in an overall reduction in RCS boron concentration, but provides acceptable margin to maintaining subcritical operation.

St. Lucie Units 1 and 2 L-2015-182 Docket Nos. 50-335 and 50-3 89 Attachment 4 License Amendment Request Page 24 of 41 INSERT 6 If only one required shutdown cooling train is OPERABLE and in operation and no required RCS loops are OPERABLE, redundancy for heat removal is lost and-the plant must be 'placed in a configuration that minimizes overall plant risk. This redundancy is obtained by making at least one steam generator available for decay heat removal via natural circulation because:

1. MODE 4 operation poses overall lower risk of core d~amage and large early radiation release than does MODE 5 (reference CE NPSD*1 186-A, Technical Justification for the Risk Informed Modification to Selected Required Action End States for CEOG PWRs, October 2001). This is particularly true with shutdown cooling impaired.

2. In MODE 4, RCS and steam generator conditions may be maintained such that failure of the operating shutdown cooling train may be mitigated by natural circulation heat removal through one or more steam generators.

Remaining within the Applicability of the LCO is acceptable because the plant risk in MODE 4 is similar to or lower than MODE 5 (reference CE NPSD-1 186-A, Technical Justification for the Risk Informed Modification to Selected Required Action End States for CEOG PWRs, October 2001). However, voluntary entry into MODE 5 may be made as it is also an acceptable low-risk state. These ACTIONs are modified by a Note that states that LCO 3.0.4.a is not applicable when entering HOT SHUTDOWN. This Note prohibits the use of LCO 3.0.4.a to enter HOT SHUTDOWN during startup with the [CO not met. However, there is no restriction on the use of LCO 3.0.4.b, if applicable, because LCO 3.0.4.b requires performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of entering HOT SHUTDOWN, and establishment of risk management actions, if appropriate.

Surveillance testing of the air lock seals provides assurance that the overall air lock leakage will not become excessive due to seal damage during the intervals between air lock leakage tests. IlNSERT 8t 314.6.1.4 INTERNAL PRESSURE The limitations on containment internal pressure ensure that (1) the containment structure, is prevented from exceeding its design negati*.~

pressure differential with respect to the annulus atmosphere of8,7 psi and (2) the containment peak pressure does not exceed the design pressure of 44 psig during loss of coolant accident conditions.

The maximum peak pressure expected to be obtained from a loss of coolant accident is 43.48 psig. The limit of 0.4 psig for initial positive containment pressure will limit the maximum peak pressure to less than the design pressure of 44 psig and is consistent with the safety analyses.

[INSERT 10J 3/4.6.1.5 AIR TEMPERATURE The limitation on containment average air temperature ensures that the peak containment vessel temperature does not exceed the containment vessel design temperature of 264°F during steam line break and loss of coolant accident conditions and is consistent with the safety analyses. *NET 2 3t4.6.1.6 CONTAINMENT VESSEL STRUCTURAL INTEGRITY The limitation ensures that the structural integrity of the containment steel vessel will be maintained comparable to the original design standards for the life of the facility. Structural integrity is required to ensure that the vessel will withstand the maximum pressure of 43.48 psig in the event of the limiting design basis loss of coolant accident. A visual inspection in accordance with the Containment Leakage Rate Testing Program is sufficient to demonstrate this capability.

Ensuring that the containment spray pump discharge preSsure iS met satisfies the periodic surveillance requirement to detect gross degradation caused by impeller structural damage or other hydraulic component problems. Along with this requirement,Section XI of the ASME Code verifies the pump developed head at one point on the pump characteristic curve to verify 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 Xl of the ASME Code provides the activities and frequencies necessary to satisfy the requirements.

314.6.2.2 IODINE REMOVAL SYSTEM The OPERABILITY of the Iodine Removal System ensures that sufficient N2 H4 is added to the containment spray in the event of 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. The contained water volume limit includes an allowance for water not usable because of tank discharge line location or other physical characteristics.

These assumptions are consistent with the iodine removal efficiency assumed in the safety analyses.

Containment isolation within the time limits specified for those isolation valves designed to close automatically ensures that the release of radioactive material to the environment will be consistent with the assumptions used in the analyses for a LOCA.

The 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months allowable outage time (AOT) is reasonable based on the low probability of a D8A occurring during this time period, and the use of mitigating actions.

In addition, the 90 day AOT is a reasonable time to diagnose, plan and possibly repair, and test most problems with the ORE boundary.

The Surveillance Requirement (SR) 4.7.7.e verifies the OPERABILITY of the GRE boundary by testing for unfiltered air inleakage past the CRE boundary and into the GRE. The details of the testing are specified in the Control Room Envelope Habitability Program.

The CRE is considered habitable when the radiological dose to GRE occupants calculated in the licensing basis analyses of DBA consequences is no more than 5 rem TEDE and the GRE occupants are protected from hazardous chemicals and smoke. This SR verifies that the unfiltered air infleakage into the GRE is no greater than the flow rate assumed in the licensing basis analyses of OBA consequences. When unfiltered air inleakage is greater than the assumed flow rate in Modes 1, 2, 3, and 4, ACTION b must be taken. Required ACTION b.3 allows time to restore the GRE boundary to OPERABLE status provided mitigating actions can ensure that the GRE remains within the licensing basis habitability limits for the occupants following an accident. Compensatory measures are discussed in Regulatory Guide 1.196, Section C.2.7.3, which endorses, with exceptions, NEI 99-03, Section 8.4 and Appendix F. These compensatory measures may also be used as mitigating actions as required by Required Action b.2.

Temporary analytical methods may also be used as compensatory measures to restore OPERABILITY, as discussed in letter from Eric J. Leeds (NRC) to James W. Davis (NEI) dated January 30, 2004, "NEI Draft White Paper, Use of Generic Letter 91-18 Process and Alternative Source Terms in the Context of Control Room Habitability:" Options for restoring the GRE boundary to OPERABLE status include changing the licensing basis DBA consequence analysis, repairing the GRE boundary, or a combination of these actions.

Depending upon the nature of the problem and the corrective action, a full scope inleakage test may not be necessary to establish that the GRE boundary has been restored to OPERABLE status.

Remaining within the Applicability of the LCO is acceptable because the plant risk in HOT SHUTDOWN is similar to or lower than COLD SHUTDOWN (reference CE NPSD-1 186-A, Technical Justification for the Risk Informed Modification to Selected Required Action End States for CEOG PWRs, October 2001). In HOT SHUTDOWN there are more accident mitigation systems available and there is more redundancy and diversity in core heat removal mechanisms than in COLD SHUTDOWN. However, voluntary entry into COLD SHUTDOWN may be made as it is also an acceptable low-risk state. These ACTIONs are modified by a Note that states that LCO 3.0.4.a is not applicable when entering HOT SHUTDOWN. This Note prohibits" the use of LCO 3.0.4.a to enter HOT SHUTDOWN during startup with the LCO not met. However, there is no restriction on the use of LCO 3.0.4.b, if applicable, because LCO 3.0.4.b requires performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of entering HOT SHUTDOWN, and establishment of risk management actions, if appropriate. LCO 3.0.4 is not applicable to, and the Note.

does not preclude, changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of a.
