L-2011-445 Page 1 of 6 St Lucie Unit 1 Exemption Request from the Requirements of 10 CFR 26.205(d)(3)

Supportinq Analysis Summary Description Pursuant to 10 CFR 26.9, Specific exemptions, Florida Power & Light Company (FPL) hereby requests a one-time exemption from portions of 10 CFR 26.205(d)(3) for St Lucie Unit 1.

Currently, 10 CFR 26.205(d)(4) and (d)(5) permit the use of less restrictive working hour limitations during the first 60 days of a unit outage, in lieu of the on-line working hour requirements in 10 CFR 26.205(d)(3). This proposed exemption would allow the use of less restrictive outage working hour limitations described in 10 CFR 26.205(d)(4) and (d)(5) to support the activities related to the upcoming Unit 1 extended power uprate (EPU) refueling outage currently scheduled to start November 27, 2011. The outage is currently scheduled for approximately 100 days with the potential for a greater number of days due to extensive modifications. The proposed exemption would allow FPL the scheduling flexibility needed during the EPU refueling outage for the outage periods when increased manpower is needed to complete activities related to the initial phase of the outage (core offload), and the final phase of the outage which includes core reload, system walkdowns, surveillance testing and startup testing.

The proposed exemption would apply to operations (who also compose the fire brigade),

maintenance, security, chemistry and radiation protection personnel as defined in 10 CFR 26.4(a)(1) through (a)(5).

The proposed exemption request will not be applicable to personnel performing work as defined in 10 CFR 26.4(a)(1) through (a)(5) who are not involved in the work schedule phases described in this exemption request. Personnel not working the schedules in the proposed exemption request will continue to meet the work hour controls of 10 CFR 26.205(d)(4) and (d)(5) during the first 60 days of the outage. Any needed extensions of the 60 day outage period will be implemented per 10 CFR 26.205(d)(6).

Detailed Description On November 27, 2011, St Lucie Unit 1 will begin an EPU refueling outage. This outage is longer than normal due to extensive modifications that are being performed related to the FPL application for EPU. A typical refueling outage is usually performed in approximately 4 to 6 weeks, depending on the work scope for the particular refueling outage. The typical refueling outage can be categorized into three distinct periods: Phase 1, the period from unit shutdown to completion of the core offload window; Phase 2, the defueled window; and Phase 3, the period from commencement of core reload to startup testing.

During Phase 1, Unit 1 will enter cold shutdown and offload the reactor core. During this phase EPU will perform plant walkdowns and project preparation for work during the defueled window.

L-2011-445 Page 2 of 6 During Phase 2, the defueled window, multiple projects related to the EPU will be implemented. This extended defueled window is required to facilitate implementation of multiple projects.

Phase 3 encompasses the core reload, reactor reassembly, surveillance testing and startup testing prior to power ascension. During this period the fuel will be reloaded into the core followed by startup testing. The EPU project requires the installation of new systems and modification of currently installed systems. Extensive system restoration walkdowns and testing are required to be performed prior to the restart of St Lucie Unit 1.

The St Lucie Unit 1 EPU outage duration is currently scheduled for approximately 100 days and is scheduled to be completed in March 2012. FPL recognizes that the current work hour rule provides some flexibility by banking hours during the first 60-days of a refueling outage.

10 CFR 26.20 5(d)(4) and (d)(5) permit the use of less restrictive working hour limitations during the first 60 days of a unit outage, in lieu of the on-line working hour requirements in 10 CFR 26.205(d)(3). In addition, 10 CFR 26.205(d)(6) allows the extension of the 60-day period in 7-day increments for each non-overlapping 7-day period an individual works not more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> during the first 60 days of a unit outage. However, the current Unit 1 outage schedule is resource loaded such that the full complement of the critical resources (Operations Maintenance, Radiation Protection, Maintenance, Chemistry and Security) is utilized during the phase 1 (core offload) and phase 3 (core reload and start-up testing) to ensure safe and effective execution of the three phases of the EPU outage. Even if FPL did not use the full complement of critical resources in phase 1 (10-20 days) of the EPU refueling outage, the remaining complement would not be able to bank enough days to support the timing of the phase 3 refueling outage activities. Based on phase 1 duration, FPL critical work groups are only able to bank 14 days allowing, at maximum, an extension of the 60-day refueling period to day 74.

Requested Exemption FPL is requesting an one time exemption from the requirements of 10 CFR 26.205(d)(3). The proposed one-time exemption from the provisions of 10 CFR 26.205(d)(3) would allow the application of the less restrictive outage work hours described in 10 CFR 26.205(d)(4) and (d)(5) to support Phase 3 of the St Lucie Unit 1 EPU refueling outage. The proposed exemption would apply to operations (who also compose the fire brigade), maintenance, security, chemistry and radiation protection personnel as defined in 10 CFR 26.4(a)(1) through (a)(5). The requested exemption will provide FPL the schedule flexibility to ensure increased manpower for the critical groups identified in this exemption is available related to core reload, system walkdowns, surveillance testing and startup testing activities.

St Lucie Unit 1 proposes to meet the less restrictive outage work hours described in 10 CFR 26.205(d)(4) and (d)(5) for Phase 1, of the EPU refueling outage. Phase 2 is the period following the initial outage period. During Phase 2, St Lucie Unit 1 will adhere to the on-line working hour requirements in 10 CFR 26.205(d)(3) for a minimum of 5 weeks. This 5-week minimum period of on-line hours is a reset period that will ensure the covered workers will not be fatigued prior to starting Phase 3, the exemption period. During Phase 3, the exemption period, St Lucie Unit 1 will meet the less restrictive outage work hours described in 10 CFR 26.205(d)(4) and (d)(5) to support the core reload and startup testing window of the refueling outage. The proposed exemption period would be applicable for 60 days consistent with the

L-2011-445 Page 3 of 6 requirements described in 10 CFR 26.205(d)(4) and (d)(5). The exemption period would start anytime after the minimum 5-week reset period of on-line working hours is completed. In accordance with 10 CFR 26.205(d)(6), the exemption period may be extended in 7-day increments for each non-overlapping 7-day period an individual works not more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> during the first 60 days of the exemption period.

During Phase 3, the exemption period, St Lucie Unit 1 will apply the outage work hour limitations of 10 CFR 26.205(d)(4) and (d)(5), such that the individuals specified in 10 CFR 26.4(a)(1) through (a)(3) have at least 3 days off in each successive (i.e., non-rolling) 15-day period, the individuals specified in 10 CFR 26.4(a)(4) have at least 1 day off in any 7-day period, and the individuals specified in 10 CFR 26.4 (a)(5) have at least 4 days off in each successive, non-rolling 15-day period.

Provided below is a discussion of each affected work group along with the reasons for the request for the exemption during Phase 3 and the activities related to the St Lucie Unit 1 EPU refueling outage.

Operations [(10 CFR 26.4(a)(1) and (a)(3)1 Operations personnel activities include plant startup demands, which involve returning plant systems to service, post-maintenance, EPU modification, and surveillance testing, support of instrument and valve lineups, system walkdowns, and response to emergent equipment issues.

Increased Operations staffing levels during the startup period, created by implementation of the less restrictive outage work hour limits ensure adequate staffing to perform the increased activities associated with plant startups, particularly following an extensive refueling outage that involves EPU modifications. Note that the Fire Brigade members (10 CFR 26.4(a)(3)) at St Lucie Unit 1 are on-shift operations personnel and are impacted by the activities described above.

Chemistry [(10 CFR 26.4(a)(2)1 Chemistry technicians provide the on-site emergency response organization minimum shift complement per 10 CFR 26.4(a)(2). Chemistry personnel activities also include plant startup demands, which involve additional chemistry sampling, monitoring of chemistry parameters and water processing with increased demands from Operations as the plant moves through Mode changes. Increased Chemistry staffing levels during the startup period, created by implementation of the less restrictive outage work hour limits ensure adequate staffing to perform the increased activities associated with plant startups, particularly following an extensive refueling outage that involves EPU modifications.

Radiation Protection [(10 CFR 26.4(a)(2)1 Radiation Protection technicians provide the on-site emergency response organization minimum shift complement per 10 CFR 26.4(a)(2). In addition, Radiation Protection provides support to Operations and Maintenance personnel accessing radiologically controlled areas and provides support to ingress of outage equipment as well as demobilizing equipment from containment for off-site shipment and on-site storage. Increased Radiation Protection staffing levels during the

L-2011-445 Page 4 of 6 startup period, created by implementation of the less restrictive outage work hour limits ensure adequate staffing to perform the increased activities resulting from EPU workscope.

Maintenance [(10 CFR 26.4(a)(4)1 Maintenance personnel activities include increased demands to support plant startup activities including additional control valve testing and start-up and tuning of turbine controls.

Maintenance personnel, including Instrumentation and Control (I&C), Mechanical and Electrical, will be required to support Operations in post-maintenance and surveillance activities.

Increased Maintenance staffing levels during the startup period, created by implementation of the less restrictive outage work hour limits ensure adequate staffing to perform the increased activities associated with surveillance testing and startup testing, particularly following an extensive refueling outage that involves EPU modifications.

Security [(10 CFR 26.4(a)(5)1 Security personnel activities include compensatory measures associated with controlling access with increased work activities in addition to the increased support required for the demobilization of equipment and its removal from the protected area. Increased Security staffing levels during this period, created by implementation of the less restrictive outage work hour limits ensure adequate staffing to perform the increased activities associated with EPU modifications.

Regulatory Evaluation The one-time exemption from the requirements of 10 CFR 26.205(d)(3) is requested in accordance with 10 CFR 26.9, Specific exemptions. Specifically, the NRC may grant exemptions from the regulations that are determined to be authorized by law and will not endanger life or property or the common defense and security, and are otherwise in the public interest.

10 CFR 26, Subpart I, Managing Fatigue, as discussed in Federal Register Notice 73 FR 16966, dated March 31, 2008, was issued to ensure that nuclear power plant licensees ensure against worker fatigue by establishing clear and enforceable requirements. The minimum days off work hour control requirements for on-line work hours are established in 10 CFR 26.205(d)(3) to address the long-term work hour controls allowing occasional use of extended work hours for short periods of time.

FPL is requesting a one-time exemption from the requirements of 10 CFR 26.205(d)(3) to implement the outage work hour controls in 10 CFR 26.205(d)(4) and (d)(5) to support Phase 3 of the St Lucie Unit 1 EPU refueling outage. 10 CFR 26.205(d)(4) and (d)(5) permit the use of less restrictive working hour limitations during the first 60 days of a unit outage, in lieu of the on-line working hour requirements in 10 CFR 26.205(d)(3). The less restrictive days off requirements of 10 CFR 26.205(d)(4) and (d)(5) provide licensees flexibility in scheduling days off while requiring the more intensive work schedules that accompany a unit outage. In addition, 10 CFR 26.205(d)(6) allows the extension of the 60-day period in 7-day increments for each non-overlapping 7-day period an individual works not more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> during the first 60 days of a unit outage.

L-2011-445 Page 5 of 6 The proposed one-time exemption would allow the less restrictive working hour limitations associated with outages, as defined in 10 CFR 26.205(d)(4) and (d)(5), to address the increased manpower requirements related to core reload, system walkdowns, surveillance testing and startup physics testing prior to returning the unit to service. The proposed exemption period (Phase 3) would be applicable for 60 days as described in 10 CFR 26.205(d)(4) and (d)(5) and the exemption period would start anytime after the minimum 5-week reset period of on-line working hours is completed. The exemption period may be extended in 7-day increments as described in 10 CFR 26.205(d)(6) for each non-overlapping 7-day period an individual works not more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> during the first 60 days of the exemption period.

The proposed exemption is applicable during Phase 3 of the refueling outage. Implementation of the proposed exemption is dependent on meeting the requirements imposed during Phases 1 and 2 of the refueling outage. Phase 1 is an initial outage period during which the requirements of 10 CFR 26.205(d)(4) and (d)(5) will be met. Phase 2 is a reset period scheduled for a minimum of 5 weeks. During the 5 week period, affected personnel will meet the on-line minimum days off requirements and work hour controls of 10 CFR 26.205(d)(3). The minimum days off work hour control requirements for on-line work hours are established in 10 CFR 26.205(d)(3) to address the long-term work hour controls allowing occasional use of extended work hours for short periods of time. Working the more restrictive on-line work hours prior to the period of exemption will provide assurance that cumulative fatigue will not compromise the workers' ability to safely and competently perform their duties during Phase 3 of the outage, referred to as the exemption period. The outage work hour controls and minimum days off requirements defined in 10 CFR 26.205(d)(4) and (d)(5) are designed to ensure that individuals have sufficient periodic long-duration breaks to prevent cumulative fatigue from affecting their ability to safely and competently perform their duties. The outage minimum day off requirements in 10CFR 26.205(d)(4) and (d)(5) serve the same general function as the on-line minimum day off requirements of 10 CFR 26.205(d)(3). The proposed approach of implementing a reset period prior to resuming the less restrictive work hours under the exemption period is supportive of reducing worker fatigue in an extended refueling outage.

The proposed exemption would apply to operations (who also compose the fire brigade),

maintenance, security, chemistry and radiation protection personnel as defined in 10 CFR 26.4(a)(1) through (a)(5). The proposed exemption request will not be applicable to personnel performing work as defined in 10 CFR 26.4(a)(1) through (a)(5) who are not involved in the work schedule phases described in the exemption request below. Personnel not working the schedules in the proposed exemption request will continue to meet the work hour controls of 10 CFR 26.205(d)(4) and (d)(5) during the first 60 days of the outage. Any needed extensions of the 60 day outage period will be implemented per 10 CFR 26.205(d)(6).

Authorized By Law The proposed one-time exemption is authorized by law in that no other law prohibits the activities that would be authorized by the exemption. The proposed one-time exemption does not result in a violation of the Atomic Energy Action of 1954, as amended, or the Commission's regulations. Notwithstanding the exemption to 10 CFR 26.205(d)(3), FPL will continue to be in compliance with all other requirements in 10 CFR 26.

Will Not Endanger Life Or Property

L-2011-445 Page 6 of 6 FPL is requesting the use of the outage work hour controls described in 10 CFR 26.205(d)(4) and (d)(5) following a minimum of a 5-week reset period where on-line minimum days off requirements are applied to the affected work groups. The 5-week minimum period of on-line hours as described in 10 CFR 26.205(d)(3) is a reset period that will ensure the covered workers will not be fatigued prior to restarting the less restrictive outage work hours described in 10 CFR 26.205(d)(4) and (d)(5) to support the core reload and startup testing window of the refueling outage. The minimum days off requirement in 10 CFR 26.205(d)(4) and (d)(5) serves the same general function as the minimum day off requirements of 10 CFR 26.205(d)(3). The reset period will ensure that cumulative fatigue will not compromise the abilities of the individuals to safely and competently perform their duties during the exemption period. Based on these considerations, no new accident precursors are created by permitting a one-time exemption to the work hour rules. FPL will effectively manage fatigue for the cover individuals.

Thus, the probability of postulated accidents is not increased. Therefore, the proposed exemption will not endanger life or property.

Will Not Endanger the Common Defense and Security FPL is requesting a one time exemption to allow the use of less restrictive work hour limitations as described in 10 CFR 26.205(d)(4) and (d)(5). The exemption period follows the initial outage work hour period (15-25 days) and the on-line work hours reset period scheduled for a minimum of 5 weeks. Working the more restrictive on-line work hours prior to the period of exemption will provide assurance that cumulative fatigue will not compromise the workers ability to safely and competently perform their duties during the period of the exemption request. The one time exemption is requested to support the core reload and startup testing window of the refueling outage. Therefore, the proposed exemption will not endanger the common defense and security.

Otherwise in the Public Interest The proposed exemption supports the St Lucie Unit 1 EPU refueling outage that includes activities associated with EPU modifications and the related surveillance and startup testing requirements. The proposed one time exemption would allow the less restrictive working hour limitations as described in 10 CFR 26.205(d)(4) and (d)(5). The exemption period follows the initial outage work hour period and the on-line work hours reset period scheduled for a minimum of 5 weeks. Working the more restrictive on-line work hours prior to Phase 3, the exemption period, will provide assurance that cumulative fatigue will not compromise the workers ability to safely and competently perform their duties during the period of the exemption request. The outage work hour limitations increase the availability of the staff to work through the manpower intensive periods of the EPU refueling outage including core reload, system walkdowns, surveillance testing, and startup testing, all necessary prior to returning the unit to service.

Therefore, the proposed exemption is in the public interest.

L-2011-445 Page 1 of 3 ATTACHMENT 2 Environmental Assessment One-Time Exemption from the Requirements of 10 CFR 26.205(d)(3)

Florida Power & Light Company (FPL) is requesting a one-time exemption from portions of 10 CFR 26.205(d)(3) for the St Lucie Unit 1 nuclear power plant. The proposed exemption would allow the application of less restrictive working hour limitations described in 10 CFR 26.205(d)(4) and (d)(5) in lieu of the working hour limitations described in 10 CFR 26.205(d)(3), to support the St Lucie Unit 1 extended power uprate (EPU) refueling outage activities. The exemption period may be extended in 7-day increments as described in 10 CFR 26.205(d)(6) for each non-overlapping 7-day period an individual works not more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> during the first 60 days of the exemption period.

An environmental assessment for the proposed exemption follows.

1. Describe any changes to the types, characteristics, or quantities of non-radiological effluents discharged to the environment as a result of the proposed exemption.

There are no expected changes in the types, characteristics, or quantities of non-radiological effluents discharged to the environment as a result of the proposed exemption. The proposed exemption is administrative in nature and is limited to changing the timeframe when less restrictive hours can be worked. This does not result in any changes to the design basis requirements for the structures, systems, and components (SSCs) at St Lucie Unit 1 that function to limit the release of non-radiological effluents during and following postulated accidents. The SSCs associated with limiting the release of offsite non-radiological effluents will continue to perform their functions, and as a result, there is no significant non-radiological effluent impact. There are no materials or chemicals introduced into the plant that could affect the characteristics or types of non-radiological effluents. In addition, the method of operation of non-radiological waste systems will not be affected by the proposed exemption.

2. Describe any changes to liquid radioactive effluents discharged as a result of the proposed implementation.

There are no expected changes to liquid radioactive effluents discharged as a result of the proposed exemption. The proposed exemption is limited to administrative changes regarding the timeframe when less restrictive working hours can be worked and will not result in the production of any different quantity or type of radioactive material in the reactor coolant system. The proposed exemption will not result in changes to the design basis requirements for the SSCs at St Lucie Unit 1 that function to limit the release of liquid radiological effluents during and following postulated accidents. The SSCs associated with limiting the release of liquid radiological effluents will continue to perform their functions, and as a result, there is no significant liquid radiological effluent impact.

L-2011-445 Page 2 of 3

3. Describe any changes to gaseous radioactive effluents discharged as a result of the proposed exemption.

There are no expected changes to gaseous radioactive effluents discharged as a result of the proposed exemption. The proposed administrative changes to the timeframe when less restrictive working hours can be worked will not result in the production of any different quantity or type of radioactive material in the reactor coolant system. These changes will not result in changes to the design basis requirements for the SSCs at St Lucie Unit 1 that function to limit the release of gaseous radiological effluents during and following postulated accidents. The SSCs associated with limiting the release of gaseous radiological effluents will continue to perform their functions, and as a result, there is no significant gaseous radiological effluent impact.

4. Describe any change in the type or quantity of solid radioactive waste generated as a result of the proposed exemption.

There are no expected changes to solid radioactive waste generated as a result of the proposed exemption. The proposed administrative changes to the timeframe when less restrictive working hours can be worked will not result in the production of any different quantity or type of radioactive material. These changes will not result in changes to the design basis requirements for the SSCs at St Lucie Unit 1 that function to limit the release of solid radioactive waste during and following postulated accidents. In addition, radiation surveys will continue to be performed in accordance with plant radiation procedures. The SSCs associated with limiting the release of solid radioactive waste will continue to perform their functions, and as a result, there is no significant solid radioactive waste impact.

5. What is the expected change in occupational dose as a result of the proposed exemption under normal and design basis accident conditions?

The request for exemption is related to the current St Lucie Unit 1 EPU refueling outage.

There is no additional work activities planned other than those related to the refueling outage. The FPL radiation protection program ensures that individual dose is maintained "as low as reasonably achievable" and that federal dose limits remain satisfied. The proposed administrative changes to the timeframe when less restrictive working hours can be worked will not result in changes to occupational dose as a result of the proposed exemption under normal and design basis accident conditions.

Therefore, the proposed exemption will not have a significant impact upon occupational dose.

L-2011-445 Page 3 of 3

6. What is the expected change in the public dose as a result of the proposed change under normal and design basis accident conditions?

Dose to the public will not be affected by the proposed exemption during either normal or design basis accident conditions. As noted in responses to Items 2, 3, and 4 above, there is no basis to contemplate an increased source of liquid, gaseous, or solid radiological effluents which could contribute to increased public exposure during normal operations or design basis accident conditions. The proposed administrative changes to the timeframe when less restrictive working hours can be worked do not impact systems used during normal operation nor systems used to detect or mitigate a design basis accident.

7. What is the impact to land disturbance for the proposed changes?

There is no impact to land disturbance as a result of the proposed exemption. The proposed administrative changes to the timeframe when less restrictive working hours can be worked will not result in any impact to land in the vicinity of St Lucie Unit 1.

FPL concludes that there is no significant non-radiological or radiological environmental impact associated with the proposed exemption to use the less restrictive outage work hours described in 10 CFR 26.205(d)(4) and (d)(5) to support the extended outage activities for the current St Lucie Unit 1 refueling outage. This conclusion is based on the following:

There is no significant increase in the amounts, and no significant changes in the types, of any effluents that may be released offsite; There is no significant increase in individual or cumulative occupational radiation exposure; and There is no significant increase in the potential for or consequences from a radiological accident.
