SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 251 TO RENEWED OPERATING LICENSE NO. DPR-67 AND AMENDMENT NO. 204 TO RENEWED OPERATING LICENSE NO. NPF-16 FLORIDA POWER AND LIGHT COMPANY ST. LUCIE PLANT, UNIT NOS. 1 AND 2 DOCKET NOS. 50-335 AND 50-389

1.0 INTRODUCTION

By application September 30, 2019 (Reference 1), as supplemented by letters dated April 27, 2020, and July 1, 2020 (References 2 and 3, respectively), Florida Power & Light Company (FPL) requested the U.S. Nuclear Regulatory Commissions (NRC or the Commission) approval for an emergency action level (EAL) scheme change for the St. Lucie Plant, Unit Nos. 1 and 2 (St. Lucie). The proposed changes would revise the EAL scheme to one based on the EAL scheme described in the Nuclear Energy Institute (NEI) document, NEI 99-01, Revision 6, Development of Emergency Action Levels for Non-Passive Reactors, dated November 21, 2012 (Reference 4). St. Lucie currently uses an EAL scheme based on NEI 99-01, Revision 5.

The supplements dated April 27, 2020, and July 1, 2020, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the NRC staffs original proposed no significant hazards consideration determination as published in the Federal Register on March 24, 2020 (85 FR 16684).

2.0 REGULATORY EVALUATION

The applicable regulations and guidance for emergency plans are provided in Section 2.1 and 2.2 below.

2.1 Regulations Title 10 of the Code of Federal Regulations (10 CFR), Section 50.47, Emergency plans, sets forth emergency plan requirements for nuclear power reactors. Section 50.47(b) of 10 CFR establishes the planning standards that the on-site and off-site emergency response plans must meet for the NRC staff to make a finding that there is reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency.

Specifically, as relevant to this safety evaluation (SE), 10 CFR 50.47(b)(4) requires that licensees on-site and off-site emergency response plans meet the following:

A standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters, is in use by the nuclear facility licensee, and State and local response plans call for reliance on information provided by facility licensees for determinations of minimum initial offsite response measures.

The use of a standard emergency classification and action level scheme ensures that implementation methods are relatively consistent throughout the industry for a given reactor and containment design while still permitting site-specific design considerations and preferences.

Section IV.B.1 of Appendix E, Emergency Planning and Preparedness for Production and Utilization Facilities, to 10 CFR Part 50 states, in part:

The means to be used for determining the magnitude of, and for continually assessing the impact of, the release of radioactive materials shall be described, including emergency action levels that are to be used as criteria for determining the need for notification and participation of local and State agencies, the Commission, and other Federal agencies, and the emergency action levels that are to be used for determining when and what type of protective measures should be considered within and outside the site boundary to protect health and safety. The emergency action levels shall be based on in-plant conditions and instrumentation in addition to onsite and offsite monitoring. By June 20, 2012, for nuclear power reactor licensees, these action levels must include hostile action that may adversely affect the nuclear power plant.

Section IV.B.2 of Appendix E to 10 CFR Part 50 states:

A licensee desiring to change its entire emergency action level scheme shall submit an application for an amendment to its license and receive NRC approval before implementing the change. Licensees shall follow the change process in

§ 50.54(q) for all other emergency action level changes.

2.2 Guidance The EAL development guidance was initially established in Generic Letter 79-50, dated October 10, 1979 (Reference 5). This guidance was subsequently revised in NUREG-0654/FEMA-REP-1 (NUREG-0654), Revision 1, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, dated November 1980 (Reference 6), which was endorsed by NRC Regulatory Guide (RG) 1.101, Revision 2, Emergency Planning and Preparedness for Nuclear Power Reactors, dated October 1981 (Reference 7), as an approach acceptable to the NRC for the development of an EAL scheme.

As industry and regulatory experience was gained with the implementation and use of EAL schemes, the industry issued revised EAL scheme development guidance to reflect lessons learned, numerous of which have been provided to the NRC for review and endorsement as generic (i.e., non-site-specific) EAL development guidance. Most recently, NEI developed NEI 99-01, Revision 6, which was endorsed by the NRC in a letter dated March 28, 2013, as acceptable generic EAL scheme development guidance (Reference 8).

Although the EAL development guidance contained in NEI 99-01, Revision 6, is generic and may not be entirely applicable for some non-passive, large light-water reactor designs, it bounds the most typical accident and event scenarios for which emergency response is necessary, in a format that allows for industry standardization and consistent regulatory oversight. Licensees may choose to develop site-specific EAL schemes using NEI 99-01, Revision 6, with appropriate site-specific alterations as applicable.

NRC Regulatory Issue Summary (RIS) 2003-18, Revision 4, Use of NEI 99-01, Methodology for Development of Emergency Action Levels, dated October 8, 2003, including Supplements 1 and 2 (Reference 9), also provides guidance for developing or changing a standard EAL scheme. In addition, this RIS and its supplements provide recommendations to assist licensees, consistent with Section IV.B.2 of Appendix E to 10 CFR Part 50, in determining whether to seek prior NRC approval of deviations from the guidance.

In summary, the NRC staff considers NEI 99-01, Revision 6, as an acceptable method to develop site-specific EALs that meet the requirements of Section IV.B of Appendix E to 10 CFR Part 50 and planning standard 10 CFR 50.47(b)(4), with the understanding that licensees may want to develop EALs that differ from the guidance document as allowed in RG 1.101.

2.3 NRC Staff Review In its application dated September 30, 2019, as supplemented by letters dated April 27, 2020, and July 1, 2020, the licensee proposed to revise the EAL scheme for St. Lucie based on NEI 99-01, Revision 6. The licensee submitted the proposed EAL scheme, the technical basis containing an evaluation and rationale for each proposed EAL change, and a comparison matrix providing a comparison of the proposed initiating conditions, mode applicability, and EAL wording to that found in NEI 99-01, Revision 6. The comparison matrix also included a description of global changes applicable to the EAL scheme and a justification for any differences or deviations from NEI 99-01, Revision 6. The application stated that the licensee used the terms difference and deviation as defined in RIS 2003-18, as supplemented, when comparing its proposed site-specific EALs to the generic EALs in NEI 99-01, Revision 6.

The NRC staff reviewed the application, as supplemented, and verified that the proposed EAL scheme is consistent with the guidance provided in NEI 99-01, Revision 6, to ensure that the proposed EAL scheme meets the requirements of Section IV.B of Appendix E to 10 CFR Part 50 and planning standard 10 CFR 50.47(b)(4). However, the NRC staff found that both the current and proposed EALs have modifications from the NEI 99-01, Revision 6, guidance due to specific plant design and licensee preference.

In reviewing the application, as supplemented, the NRC staff also verified that the instrumentation and setpoints derived for this proposed EAL scheme are consistent with the overall EAL scheme development guidance, address the site-specific implementation strategies provided, and are consistent with a standard EAL scheme.

Although the EALs must be site-specific, the NRC staff reviewed the proposed EALs for the following key characteristics of an effective EAL scheme to ensure:

Consistency, including standardization of intent, if not in actual wording (i.e., the EALs would lead to similar decisions under similar circumstances at different plants);

Human factors engineering and user friendliness; Potential for emergency classification level upgrade only when there is an increasing threat to public health and safety; Ease of upgrading and downgrading the emergency classification level; Thoroughness in addressing issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654 (i.e., the EALs are unambiguous and are based on site-specific indicators);

Technical completeness for each classification level; Logical progression in classification for multiple events, and The use of objective and observable values.

The NRC staff verified that the proposed EAL scheme uses objective and observable values; is worded in a manner that addresses human factors engineering and user friendliness concerns; follows logical progressions for escalating events and allows for event downgrading and upgrading based upon the potential risk to the public health and safety. The NRC staff verified that risk assessments were appropriately used to set the boundaries of the emergency classification levels and ensure that all EALs that trigger the declaration of an emergency classification level are in the same range of relative risk. In addition, the NRC staff verified that the proposed EAL scheme is technically complete for each emergency classification level and is accurate and consistent with EAL schemes implemented at similarly designed plants.

To aid in understanding the nomenclature used in this safety evaluation, the following conventions are used (e.g., RU1 or RA1):

The first letter signifies the EAL recognition category:

o A or R - Abnormal Radiation Levels/Radiological Effluent, o C - Cold Shutdown/Refueling System Malfunction, o E - Independent Spent Fuel Storage Installation, o F - Fission Product Barrier, o H - Hazards and Other Conditions Affecting Plant Safety, and o S or M - System Malfunction.

The second letter signifies the emergency classification level:

o U = Notification of Unusual Event (Unusual Event),

o A = Alert, o S = Site Area Emergency, and o G = General Emergency.

The number is the applicable number from the site-specific EAL scheme.

An EAL set refers to EALs within an EAL Recognition Category that include an escalation path for one or more emergency classification levels. Not all EAL Recognition Categories require an EAL set.

This safety evaluation uses the numbering system from the proposed site-specific EAL scheme; however, the numbering system from the generic EAL scheme development guidance contained in NEI 99-01, Revision 6, is annotated in brackets to aid in cross-referencing the site-specific EAL numbering convention with that of the guidance, where applicable.

3.0 TECHNICAL EVALUATION

3.1 Recognition Category R - Abnormal Radiation Levels/Radiological Effluent 3.1.1 EAL Set RU1/RA1/RS1/RG1 [AU1/AA1/AS1/AG1]

The intent of this EAL set is to ensure that an emergency classification level is declared upon site-specific indications of a release of radioactivity (gaseous or liquid). In recognition of the lower possible radioactivity concentrations, the assessment of liquid releases is limited to the Unusual Event and Alert classification levels. This set provides for accident assessments using pre-calculated values based on assumed conditions, real-time parameters, and field monitoring results.

The NRC staff verified that the progression from an Unusual Event to a General Emergency classification level is appropriate and consistent with EAL scheme development guidance.

RU1 - This EAL addresses a potential decrease in the level of safety of the plant as indicated by a low-level radiological release that exceeds regulatory commitments for an extended period (e.g., an uncontrolled release).

RA1 - This EAL addresses a release of gaseous or liquid radioactivity that results in projected or actual off-site doses greater than or equal to 1 percent of the U.S. Environmental Protection Agency (EPA) early phase protective action guides (PAGs) (Reference 10).

RS1 - This EAL addresses a release of gaseous radioactivity that results in projected or actual off-site doses greater than or equal to 10 percent of the EPA early phase PAGs.

RG1 - This EAL addresses a release of gaseous radioactivity that results in projected or actual off-site doses greater than or equal to the EPA early phase PAGs.

The NRC staff has reviewed the proposed removal of the main steam radiation monitors from the respective effluent monitor threshold tables. The NRC staff considered that (1) the main steam radiation monitors are process monitors designed to detect gross fuel failures, (2) they are not intended to assess potential offsite release rates, and (3) that a steam generator tube leak would be bounded by the fission product barrier matrix, off-site dose assessment, or field monitoring. Based on this, the NRC staff finds this change to be acceptable.

The licensee provided justification that the proposed radiation monitors used to assess effluent gaseous release points was acceptable based on site-specific gaseous discharge paths. The licensee chose to modify this EAL set by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, ease of upgrading/downgrading, and instrumentation and setpoints for this EAL set are consistent with the overall EAL scheme development guidance, and that they address the site-specific implementation strategies provided. From this, the NRC staff determined that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL set is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for each emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL set is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL set acceptable.

3.1.2 EAL Set RU2/RA2/RS2/RG2 [AU2/AA2/AS2/AG2]

The intent of this EAL set is to ensure that an emergency classification level is declared upon site-specific indications of potential or actual damage to an irradiated fuel assembly or multiple assemblies. It addresses a lowering of water level over irradiated fuel or fuel uncovery (i.e., level below the top of the fuel), a spectrum of fuel handling accidents that result in mechanical damage to irradiated fuel (e.g., a dropped fuel assembly). Some of these EALs rely on the spent fuel pool (SFP) water level instrumentation required by NRC Order EA-12-051, Order Modifying Licenses with Regard to Reliable Spent Fuel Pool Instrumentation, dated March 12, 2012 (Reference 11).

The NRC staff has verified that the progression from an Unusual Event to a General Emergency classification level is appropriate and consistent with EAL scheme development guidance.

RU2 - This EAL addresses a decrease in water level above irradiated fuel that causes elevated radiation levels.

RA2 - This EAL addresses events that have caused imminent or actual damage to an irradiated fuel assembly or a significant lowering of water level within the SFP.

RS2 - This EAL addresses a significant loss of SFP water inventory control and makeup capability leading to imminent fuel damage and addresses NRC Order EA-12-051.

RG2 - This EAL addresses a significant loss of SFP water inventory control and makeup capability leading to a prolonged uncovery of irradiated fuel and addresses NRC Order EA-12-051.

The use of IMMINENT in the basis discussion relative to RA2.1 refers to imminent or actual damage of an irradiated fuel assembly. Section 5.5 of NEI 99-01, Revision 6, refers to making an emergency declaration when the Emergency Director determines that conditions that could lead to meeting or exceeding an EAL within a short period of time. Although the NRC staff continues to find the related RA2.1 guidance of NEI 99-01, Revision 6, to be reasonable, the NRC staff finds that the addition of IMMINENT to RA2.1 as acceptable site-specific wording. As changed, the NRC staff finds it reasonable that an Alert classification would be declared at St. Lucie whenever irradiated fuel is either uncovered or would be uncovered in a short period of time.

The licensee chose to modify this EAL set by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, ease of upgrading/downgrading, and instrumentation and setpoints for this EAL set are consistent with the overall EAL scheme development guidance and that they address the site-specific implementation strategies provided. The NRC staff determined, therefore, that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL set is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for each emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL set is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL set acceptable.

3.1.3 EAL RA3 [AA3]

The intent of this EAL is to ensure that an emergency classification level is declared when elevated radiation levels in certain plant rooms and areas are enough to preclude or impede personnel from performing actions necessary to maintain normal plant operation or to perform a normal plant cooldown and shutdown. This includes equipment in the control room and the central alarm station. The Alert classification level is primarily intended to ensure that the licensee emergency response organization (ERO) is activated to support the control room in removing the impediment to normal access, as well as assisting in quantifying potential damage to the fuel. Indications of increasing radiation levels in the plant are bounded by Recognition Category F, as well as EALs RS1 and RG1.

The licensee chose to modify this EAL by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, and instrumentation and setpoints for this EAL are consistent with the overall EAL scheme development guidance and address the site-specific implementation strategies provided, and are, therefore, consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for this emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL acceptable.

3.2 Recognition Category C - Cold Shutdown/Refueling System Malfunction 3.2.1 EAL Set CU1/CA1/CS1/CG1 [CU1/CA1/CS1/CG1]

The intent of this EAL set is to ensure an emergency classification level is declared upon a loss of reactor pressure vessel (RPV) inventory and/or reactor coolant system (RCS) leakage.

The NRC staff verified that the progression from an Unusual Event to a General Emergency classification level is appropriate and consistent with EAL scheme development guidance.

CU1 - This EAL addresses the inability to restore and maintain water level to a required minimum level (or the lower limit of a level band) or a loss of the ability to monitor RPV/RCS level concurrent with indications of reactor coolant leakage.

CA1 - This EAL addresses conditions that are precursors to a loss of the ability to adequately cool irradiated fuel in the RPV/RCS (i.e., a precursor to a challenge to the fuel clad barrier).

CS1 - This EAL addresses a significant and prolonged loss of RPV/RCS inventory control and makeup capability leading to imminent fuel damage.

CG1 - This EAL addresses the inability to restore and maintain RPV/RCS level above the top of active fuel with containment challenged.

The licensee chose to modify this EAL set by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, ease of upgrading/downgrading, and instrumentation and setpoints for this EAL set are consistent with the overall EAL scheme development guidance and that they address the site-specific implementation strategies that are provided. The NRC staff determined that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL set is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for each emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL set is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL set acceptable.

3.2.2 EAL Set CU2/CA2 [CU2/CA2]

The intent of this EAL set is to ensure that an emergency classification level is declared upon a loss of available alternating current (AC) power to emergency power electrical buses.

The NRC staff verified that the progression from an Unusual Event to an Alert classification level is appropriate and consistent with EAL scheme development guidance. The Site Area Emergency and General Emergency classification levels for this specific accident progression are bounded by EALs RS1 and RG1.

CU2 - This EAL describes a significant degradation of offsite and onsite AC power sources such that any additional single failure would result in a loss of all AC power to Safety Systems (typically classified as those systems that are safety-related, as defined in 10 CFR 50.2).

CA2 - This EAL addresses a loss of all AC power that compromises the performance of all Safety Systems requiring electric power, including those necessary for emergency core cooling, containment heat removal/pressure control, irradiated fuel heat removal, and the ultimate heat sink.

The licensee chose to modify this EAL set by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, and ease of upgrading/downgrading for this EAL set are consistent with the overall EAL scheme development guidance, and that they address the site-specific implementation strategies provided. The NRC staff determined, therefore, that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL set is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for each emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL set is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL set acceptable.

3.2.3 EAL Set CU3/CA3 [CU3/CA3]

The intent of this EAL set is to ensure that an emergency classification level is declared based on the inability to maintain control of decay heat removal.

The NRC staff verified that the progression from an Unusual Event to an Alert classification level is appropriate and consistent with EAL scheme development guidance. The progression to a Site Area Emergency and/or a General Emergency classification level is bounded by EALs RS1 and RG1.

CU3 - This EAL addresses an unplanned increase in RCS temperature above the technical specification cold shutdown temperature limit or the inability to determine RCS temperature and level.

CA3 - This EAL addresses conditions involving a loss of decay heat removal capability or an addition of heat to the RCS in excess of that which can currently be removed.

The licensee chose to modify this EAL set by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, and ease of upgrading/downgrading for this EAL set are consistent with the overall EAL scheme development guidance, and that they address the site-specific implementation strategies provided. The NRC staff determined, therefore, that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL set is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for each emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL set is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL set acceptable.

3.2.4 EAL CU4 [CU4]

The intent of this EAL is to ensure that an emergency classification level is declared upon a loss of vital direct current (DC) power that compromises the ability to monitor and control operable Safety Systems. This EAL is primarily intended to ensure that key licensee ERO members and state and local agencies are aware of the event, resources necessary to respond to the event are mobilized, and any necessary compensatory measures are promptly implemented. The Alert, Site Area Emergency and General Emergency classification levels for a protracted loss of vital DC power are bounded by EALs CA1, CA3, CS1, CG1, RA1, RS1 and RG1.

The licensee chose to modify this EAL by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, and instrumentation and setpoints for this EAL are consistent with the overall EAL scheme development guidance, and that they address the site-specific implementation strategies provided. The NRC staff determined, therefore, that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for this emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL acceptable.

3.2.5 EAL CU5 [CU5]

The intent of this EAL is to highlight the importance of emergency communications by ensuring that an emergency classification level is declared if normal communication methods for onsite and offsite personnel, or with state and local agencies including the NRC, are lost. This EAL is primarily intended to ensure that key licensee ERO members and state and local agencies are aware of the loss of communications capabilities, the resources necessary to restore communications are mobilized, and compensatory measures are promptly implemented.

Considering that a loss of emergency communications capability would not involve an actual or potential substantial degradation to the level of safety of the plant, no escalation path is necessary for this EAL.

The communication methods derived for this EAL are consistent with the overall EAL scheme development guidance.

The licensee chose to modify this EAL by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, and instrumentation and setpoints for this EAL are consistent with the overall EAL scheme development guidance, and that they address the site-specific implementation strategies provided.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL acceptable.

3.2.6 EAL CA6 [CA6]

The intent of this EAL is to ensure that an emergency classification level is declared when hazardous events lead to damage to Safety Systems. These hazardous events include, but are not limited to, an earthquake, flooding, high winds, tornado strike, explosion, fire, or any other hazard applicable for the site. This EAL is primarily intended to ensure that the licensee ERO is activated to support the control room in understanding the event impacts and restoring affected Safety System equipment to service. Indications of hazard-induced damage to components containing radioactive materials are bounded by EALs CS1, CG1, RS1 and RG1.

As described in NEI 99-01, Revision 6, an Alert classification level exists when events are in process or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant. Any releases are expected to be limited to small fractions of the EPA early phase PAG exposure levels. The guidance in NEI 99-01, Revision 6, is intended to ensure that an Alert classification level should be declared only when an actual or potential substantial degradation of the level of safety of the plant has occurred because of a hazardous event. However, there may be cases where a hazardous event only causes damage to a single Safety System component or a single Safety System train. Additionally, an Alert classification level should not be declared if the damage from the hazardous event is limited to a Safety System component or a Safety System train that was inoperable or out of service prior to the event occurring.

The licensee proposed that an Alert classification level will be declared when a hazardous event results in indications of degraded performance to one train of a Safety System with either indications of degraded performance on a second Safety System train or visible damage to a second Safety System train, such that the operability or reliability of the second Safety System train is a concern. Although different from the guidance in NEI 99-01, Revision 6, this change is acceptable, given that the guidance in NEI 99-01, Revision 6, is intended to ensure that an Alert classification level should be declared only when an actual or potential substantial degradation of the level of safety of the plant has occurred because of a hazardous event.

The licensee chose to modify this EAL by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance.

The NRC staff also verified that the EAL is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for this emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL acceptable.

3.4 Recognition Category F - Fission Product Barrier Matrix 3.4.1 EAL Set FA1/FS1/FG1 [FA1/FS1/FG1]

The intent of this EAL set is to ensure that an emergency classification level is declared upon a loss or potential loss of one or more fission product barriers. This EAL set uses plant condition-based thresholds as triggers within a particular logic configuration needed to reflect a loss or potential loss of a fission product barrier. Non-passive, large light-water reactors, like St.

Lucies, have three fission product barriers: fuel cladding, the RCS, and primary containment.

Licensees are required to develop thresholds that provide EAL decision makers input into making an event declaration based upon degradation of one or more of these fission product barriers.

There are numerous triggers used as logic inputs to decide on the appropriate emergency classification level based upon the number of loss and/or potential loss indicators that are met for each barrier. These indicators are redundant with other similar indicators in Recognition Categories R and S.

The NRC staff verified that the logic used to determine the appropriate emergency classification level is consistent with the generic EAL scheme development guidance in NEI 99-01, Revision 6. The progression from an Alert to a General Emergency classification level is appropriate and consistent with EAL scheme development guidance.

FA1 - This EAL addresses any loss or any potential loss of either the fuel clad or RCS barrier.

FS1 - This EAL addresses loss or potential loss of any two barriers.

FG1 - This EAL addresses loss of any two barriers and loss or potential loss of the third barrier.

3.5 Recognition Category H - Hazards and Other Conditions Affecting Plant Safety 3.5.1 EAL Set HU1/HA1/HS1 [HU1/HA1/HS1/HG1]

The intent of this EAL set is to ensure that an emergency classification level is declared based upon a security-related event. This EAL set was developed in accordance with the guidance from NRC Bulletin 2005-02, Emergency Preparedness and Response Actions for Security-Based Events, dated July 18, 2005 (Reference 12), and RIS 2006-12, Endorsement of Nuclear Energy Institute Guidance Enhancements to Emergency Preparedness Programs for Hostile Action, July 19, 2006 (Reference 13), for licensees to implement, regardless of the specific version of the generic EAL scheme development guidance used, or if the particular licensee developed its EAL scheme using an alternative approach. Based upon lessons-learned from the implementation and use of this EAL set, particularly the insights gained from combined security and emergency preparedness drills, FPL proposed to not develop EAL HG1, as provided in NEI 99-01, Revision 6.

EAL HG1 of NEI 99-01, Revision 6, addresses a hostile action that results in the loss of physical control of the facility. Such an action can reasonably be expected to exceed EPA early phase PAG exposure levels off-site for more than the immediate site area, which is the criteria for EAL HG7 in NEI 99-01, Revision 6. Therefore, in NEI 99-01, Revision 6, EAL HG1 is bounded by EAL HG7. Additionally, any event that could result in a radiological release in excess of EPA early phase PAGs would be bounded by EALs RG1 [AG1] or RG2 [AG2] in NEI 99-01, Revision 6. The NRC staff verified that the FPL EALs RG1, RG2, and HG7 bound the events addressed by EAL HG1 in NEI 99-01, Revision 6.

The NRC staff also verified that the progression from an Unusual Event to a Site Area Emergency classification level is appropriate and consistent with EAL scheme development guidance.

HU1 - This EAL addresses events that pose a threat to plant personnel or Safety System equipment.

HA1 - This EAL addresses the occurrence of a hostile action within the Owner Controlled Area or notification of an aircraft attack threat.

HS1 - This EAL addresses the occurrence of a hostile action within the Protected Area.

3.6.4 EAL SU5 [SU4]

The intent of this EAL is to ensure that an emergency classification level is declared when the plant has indications of RCS leakage. By design, the indications for this EAL are redundant to corresponding indicators for a loss or potential loss of fission product barriers, as well as radiation monitoring, to ensure reactor and/or fission product barrier events are recognized.

This EAL is primarily intended to ensure that key licensee ERO members are aware of the RCS leakage and support the control room in implementation of appropriate response measures.

Escalation from this emergency classification level is bounded by Recognition Category F, as well as EALs RA1, RS1 and RG1.

The licensee chose to modify this EAL by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, and instrumentation and setpoints for this EAL are consistent with the overall EAL scheme development guidance and that they address the site-specific implementation strategies provided. From this, the NRC staff determined that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for this emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL acceptable.

3.6.5 EAL Set SU6/SA6/SS6 [SU5/SA5/SS5]

The intent of this EAL set is to ensure that an emergency classification level is declared based upon the effect that a failure of the reactor protection system (RPS) may have on the plant.

The NRC staff verified that the progression from an Unusual Event to a Site Area Emergency classification level is appropriate and consistent with EAL scheme development guidance. A General Emergency classification level for this event is bounded by Recognition Category F, as well as EAL RG1.

SU6 - This EAL addresses a failure of the RPS to initiate or complete an automatic or manual reactor trip that results in a reactor shutdown, and either a subsequent operator manual action taken at the reactor control consoles or a subsequent automatic trip is successful in shutting down the reactor.

SA6 - This EAL addresses a failure of the RPS to initiate or complete an automatic or manual reactor trip that results in a reactor shutdown, and subsequent operator manual actions taken at the reactor control consoles to shut down the reactor are also unsuccessful.

SS6 - This EAL addresses a failure of the RPS to initiate or complete an automatic or manual reactor trip that results in a reactor shutdown, all subsequent operator actions to manually shut down the reactor are unsuccessful, and continued power generation is challenging the capability to adequately remove heat from the core and/or the RCS.

The licensee chose to modify this EAL set by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, ease of upgrading/downgrading, and instrumentation and setpoints for this EAL set are consistent with the overall EAL scheme development guidance and that they address the site-specific implementation strategies provided. From this, the NRC staff determined that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL set is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for each emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL set is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL set acceptable.

3.6.6 EAL SU7 [SU6]

The intent of this EAL is to highlight the importance of emergency communications by ensuring that an emergency classification level is declared if normal communication methods for on-site and off-site personnel, or with state and local agencies, including the NRC, are lost. This EAL is primarily intended to ensure that key licensee ERO members, state and local agencies, and the NRC are aware of the loss of communication capabilities, the resources necessary to restore communications are mobilized, and compensatory measures are promptly implemented.

Considering that a loss of emergency communications capability would not involve an actual or potential substantial degradation to the level of safety of the plant, no escalation path is necessary for this EAL.

The communication methods derived for this EAL are consistent with the overall EAL scheme development guidance.

The licensee chose to modify this EAL by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, and logical progression for this EAL are consistent with the overall EAL scheme development guidance and that they address the site-specific implementation strategies provided. From this, the NRC staff determined that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for this emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL acceptable.

3.6.7 EAL SU8 [SU7]

The intent of this EAL is to ensure that an emergency classification level is declared when the plant has indications of containment barrier degradation. It also addresses an event that results in high containment pressure with a concurrent failure of containment pressure control systems.

The indications for this EAL are redundant to corresponding indicators from a loss or potential loss of fission product barriers, as well as radiation monitoring, to ensure reactor and/or fission product barrier events are recognized.

This EAL is primarily intended to ensure that key licensee ERO members, state and local agencies, and the NRC are aware of significant challenges to containment integrity, and compensatory measures are promptly implemented. Escalation is bounded by Recognition Category F, as well as EALs RA1, RS1 and RG1.

The licensee chose to modify this EAL by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, and instrumentation and setpoints for this EAL are consistent with the overall EAL scheme development guidance and that they address the site-specific implementation strategies provided. From this, the NRC staff determined that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns; is technically complete for this emergency classification level; addresses issues regarding completeness and accuracy of Appendix 1 to NUREG-0654 and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL acceptable.

3.6.7 EAL Set SS2/SG2 [SS8/SG8]

The intent of this EAL set is to ensure that an emergency classification level is declared when a loss of DC power occurs, as this condition compromises the ability of the licensee to monitor and control Safety Systems.

The NRC staff verified that the progression from a Site Area Emergency to a General Emergency classification level is appropriate and consistent with EAL scheme development guidance.

SS2 - This EAL addresses a loss of vital DC power that compromises the ability to monitor and control Safety Systems.

SG2 - This EAL addresses a concurrent and prolonged loss of both AC and vital DC power.

The licensee chose to modify this EAL set by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, ease of upgrading/downgrading, and instrumentation and setpoints for this EAL set are consistent with the overall EAL scheme development guidance and that they address the site-specific implementation strategies provided. From this, the NRC staff determined that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL set is worded in an unambiguous manner that addresses human factors engineering and user-friendliness concerns, is technically complete for each emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG-0654, and uses objective and observable values based on site-specific indications.

Therefore, the NRC staff finds this EAL set acceptable.

3.6.8 EAL SA9 [SA9]

The intent of this EAL is to ensure that an emergency classification level is declared when hazardous events lead to potential damage to Safety Systems needed for the current operating mode. The hazardous events of interest include, but are not limited to, an earthquake, flooding, high winds, tornado strike, explosion, fire, or any other hazard applicable for St. Lucie. This EAL is primarily intended to ensure that the licensee ERO is activated to support the control room in understanding the event impacts and restoring affected Safety System equipment to service. Indications of hazard-induced damage to components containing radioactive materials are bounded by Recognition Category F, as well as EALs RS1 and RG1.

As described in NEI 99-01, Revision 6, an Alert classification level exists when events are in process or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant. Any releases are expected to be limited to small fractions of the EPA early phase PAG exposure levels. The guidance in NEI 99-01, Revision 6, is intended to ensure that an Alert classification level should be declared only when an actual or potential substantial degradation of the level of safety of the plant has occurred because of a hazardous event. However, there may be cases where a hazardous event only causes damage to a single Safety System component or a single Safety System train. Additionally, an Alert classification level should not be declared if the damage from the hazardous event is limited to a Safety System component or a Safety System train that was inoperable or out of service prior to the event occurring.

The licensee proposed that an Alert classification level be declared when a hazardous event results in indications of degraded performance to one train of a Safety System with either indications of degraded performance on a second Safety System train or visible damage to a second Safety System train, such that the operability or reliability of the second Safety System train is a concern. Although different from the guidance in NEI 99-01, Revision 6, this change is acceptable, considering that the guidance in NEI 99-01, Revision 6, is intended to ensure that an Alert classification level should be declared only when an actual or potential substantial degradation of the level of safety of the plant has occurred because of a hazardous event.

The licensee chose to modify this EAL by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance. The NRC staff verified that the numbering, sequencing, formatting, logical progression, and instrumentation and setpoints for this EAL are consistent with the overall EAL scheme development guidance and that they address the site-specific implementation strategies provided. From this, the NRC staff determined that they are consistent with a standard EAL scheme, as required by 10 CFR 50.47(b)(4). The NRC staff also verified that the EAL is worded in an unambiguous manner that addresses human factors engineering and user friendliness concerns, is technically complete for this emergency classification level, addresses issues regarding completeness and accuracy raised in Appendix 1 to NUREG 0654, and uses objective and observable values based on site-specific indications.

Based on the above, the NRC staff concludes that the site-specific implementation method for this EAL is consistent with the key characteristics of an effective EAL scheme (identified in Section 2.3 above) and meets the requirements of 10 CFR 50.47(b)(4) and Section IV.B of Appendix E to 10 CFR Part 50. Therefore, the NRC staff finds this EAL acceptable.

3.7 Review Summary The NRC staff has reviewed the technical bases for the proposed EAL scheme, the modifications from NEI 99-01, Revision 6, and the licensees evaluation of the proposed changes. The licensee chose to modify its proposed EAL scheme from the generic EAL scheme development guidance provided in NEI 99-01, Revision 6, to adopt a format that is better aligned with how it currently implements its EALs, as well as with site-specific writers guides and preferences. The NRC staff verified that these modifications do not alter the intent of any specific EAL within a set, recognition category, or within the entire EAL scheme described in NEI 99-01, Revision 6. Thus, the proposed changes meet the requirements in Appendix E to 10 CFR Part 50 and planning standard 10 CFR 50.47(b)(4).

The NRC staff determined that the proposed EAL scheme uses objective and observable values, is worded in a manner that addresses human factors engineering and user friendliness concerns, follows logical progressions for escalating events, and allows for event downgrading and upgrading based upon the potential risk to the public health and safety. Risk assessments were appropriately used to set the boundaries of the emergency classification levels and ensure that all EALs that trigger an emergency classification are in the same range of relative risk. In addition, the NRC staff determined that the proposed EAL scheme is technically complete and consistent with EAL schemes implemented at similarly designed plants.

The NRC staff verified that the instrumentation and setpoints derived for this proposed EAL scheme are consistent with the overall EAL scheme development guidance, address the site-specific implementation strategies provided, and are consistent with a standard EAL scheme.

Based on its review, the NRC staff finds that the licensees proposed EAL scheme is acceptable and provides reasonable assurance that the licensee can and will take adequate protective measures in the event of a radiological emergency. Specifically, the staff concludes that the licensees proposed EAL scheme and site-specific EAL technical basis document provided by letter dated September 30, 2019, as supplemented by letters dated April 27, 2020, and July 1, 2020, is acceptable for implementation.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the NRC staff notified the State of Florida official on August 17, 2020, of the proposed issuance of the amendments. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendments change requirements with respect to the installation or use of facility components located within the restricted area as defined in 10 CFR Part 20 because the amendments approve an acceptable EAL scheme that is required for operation of the facility.

The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released off-site, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on such finding published in the Federal Register on March 24, 2020 (85 FR 16684). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).

Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of these amendments.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commissions 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.
