1.0 INTRODUCTION

By letter dated June 30, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14192A022), as supplemented by letter dated August 19, 2014 (ADAMS Accession No. ML14241A422), Florida Power & Light Company (FPL, the licensee) submitted an application for amendment to revise the implementation date of Cyber Security Plan (CSP) Milestone 8. Milestone 8 of the CSP is concerned with the full implementation of the CSP.

Portions of the licenseesJune 30 and August 19, 2014, letterscontain sensitive unclassified non-safeguards information and, accordingly, those portions are withheld from public disclosure in accordance with the provisions of 10CFR2.390(d)(1). The accession numbers cited in the above paragraph refer to the publicly available redacted version.

For the subject application, as supplemented, the Nuclear Regulatory Commission (NRC) published its proposed no significant hazards consideration in the Federal Registeron November 4, 2014 (79 FR 65431).

2.0 REGULATORY EVALUATION

The NRC staff had previously reviewed and approved the licensees CSP implementation schedule by Amendment No. 211 and 160 for Saint Lucie Plant, Unit Nos. 1 and 2, respectively, and concurrently with the incorporation of the CSP into the current licensing bases. Subsequently, the NRC staff issued Amendment Nos. 214 and 164 to revise Milestone 6 for each unit, respectively.

The NRC staff considered the following regulatory requirements and guidance in its review of the current application for amendment to modify the existing CSP implementation schedule:

(1) Titlte 10 of the Code of Federal Regulations,Sectin 73.54 (10CFR73.54) states:

..Each [CSP] submittal must include a proposed implementation schedule. Implementation of the licensees cyber security program must be consistent with the approved schedule.

Enclosure

(2) Amendment No. 211 and Amendment No. 160, dated August 31, 2011, which approved the licensees CSP and implementation schedule, include the following statement: St.

Lucie shall fully implement and maintain in effect all provisions of the Commission-approved cyber security plan (CSP), including changes made pursuant to the authority of 10 CFR 50.90 and 10 CFR 50.54(p).

(3) In a publically available NRC memorandum, R. Feltsto B. Westreich,dated October 24, 2013 (ADAMS Accession No. ML13295A467), the NRC staff listed criteria that it would consider during its evaluations of licensees requests to postpone their cyber security program implementation date (commonly known as Milestone 8).

3.0 TECHNICAL EVALUATION

3.1 Licensees Requested Change By Amendment Nos. 211 (for Unit 1) and 160 (for Unit 2)the NRC staff approved the licensees CSP implementation schedule, as discussed in the safety evaluation issued concurrently with those amendments. The implementation schedule had been submitted by the licensee based on a template (ADAMS Accession No. ML110600218)prepared by the Nuclear Energy Institute (NEI), which the NRC staff found acceptable for licensees to use to develop their CSP implementation schedules. The licensees proposed implementation schedule for the St. Lucie Plant CSP identified completion dates and bases for the following eight milestones:

1) Establish the Cyber Security Assessment Team (CSAT);

2) Identify Critical Systems (CSs) and Critical Digital Assets (CDAs);

3) Install a data diode device between lower level devices and higher level devices;

4) Implement the security control Access Control For Portable And Mobile Devices;

5) Implement observation and identification of obvious cyber-related tampering to existing insider mitigation rounds;

6) Identify, document, and implement cyber security controls in accordance with Mitigation of Vulnerabilities and Application of Cyber Security Controls for CDAs that could adversely impact the design function of physical security target set equipment;

7) Ongoing monitoring and assessment activities for those target set CDAs whose security controls have been implemented;

8) Fully implement the CSP.

Currently, Milestone 8 of the licensees CSP requires the licensee to fully implement the CSP by December 31, 2015. In its June 30, 2014, application, the licenseeproposed to change the Milestone 8 completion date to December 31, 2017. The licensees application addressed the 8 criteria in the NRCs October 24, 2014 guidance memorandum.

The licensee provided the following information pertinent to each of the criteria identified in the NRC guidance memorandum cited in Section 2.0 above.

(1) Identification of the specific requirement or requirements of the cyber security plan that the licensee needs additional time to implement.

The licensee stated that the specific CSP requirement requiring additional time to implement is CSP Section 3.1, Analyzing Digital Computer Systems and Networks

Applying CyberSecurity Controls. The licensee provided a list of activities required to implement the CSP requirements.

(2) Detailed justification that describes the reason the licensee requires additional time to implement the specific requirement or requirements identified.

The licensee stated that CDA assessment work is resource-intensive.St. Lucie has approximately 2250 CDAs.

• Assessment is challenging due to uncertainty surrounding security controls interpretation.

• The licensee underestimated the level of effort necessary to address security controls.

• Rework is a major concern - budgets are approved in advance on a definedscope of work.

• The licensee will have to increase resources to cope with magnitude of the work identified.

The licensee stated that remediation activities need to be carefully considered:

• Security controls modifications are unique and new to the plant and suppliers.

• Plant modifications cannot affect plant safety and operation.

The licensee stated that there are change management challenges:

• Cyber security integrates into day-to-day plant operations, maintenance, engineering and procurement activities.

• Integration of controls takes longer than anticipated due to work control process and maintenance activities.

• Additional burden on maintenance to address security controls integrity during work on CDAs.

• Cyber security and controls being implemented on CDAs are new to maintenance, engineering and operations.

• Work control planners are challenged by the nuances associated with cyber security controls.

• Training and qualifications of maintenance personnel is a challenge.

• Modifications that added security controls have added new change management issues.

The licensee stated that site training needs and schedules need to be revised and training resources need to be addressed.

(3) A proposed completion date for Milestone 8 consistent with the remaining scope of work to be conducted and the resources available.

The licensee proposed a Milestone 8 completion date of December 31, 2017. The licensee also stated that changing the completion date of Milestone 8 will encompass two additional refueling outages per unit and provides adequate time to complete CDA

assessment, implement design modifications based on assessment results, update existing procedures and develop new procedures to complete full implementation of the CSP.

(4) An evaluation of the impact that theadditional timetoimplement therequirementswill haveon theeffectivenessofthelicensees overallcyber security program in the context of milestones already completed.

The licensee stated that, based on the CSP program implementation activities already completed and activities currently in progress, St. Lucie is secure and FPL will continue to ensure that digital computer and communications systems and networks are adequately protected against cyber attacks during implementation of the remainder of the program by the proposedMilestone 8 date of December 31, 2017. The completed activities provide a high degree of protection against cyber-attacks while St. Lucie implements the full CSP. The licensee provided details about implementation of each of the milestones.

(5) A description of the licensees methodology for prioritizing completion of work for critical digital assets associated with significant safety consequences and with reactivity effects in the balance of plant.

The licensee stated that its methodology for prioritizing the St. Lucie CSP Milestone 8 activities is centered on considerations for safety, security, emergency preparedness (EP), and balance-of-plant (continuity of power) consequences. The methodology is based on defense-in-depth, installed configuration of the CDA, and susceptibility to commonly identified threat vectors. Prioritization of CDA assessments begins with safety-related CDAs and continues through the lower priority non-safety-related and EP CDAs as follows:

• Safety-related CDAs

• Physical security CDAs

• Important-to-safety CDAs (including balance-of-plant CDAs that directly impact continuity of power and control system CDAs)

• Non-safety-related and EP CDAs (6) A discussion of the licensees cyber security program performance up to the date of the license amendment request.

The licensee stated that implementation of the requirements of Milestones 1 through 7 has been completed and these improvements are proviging a high degree of protection against cyber attacks, until full program implementation. Further, the licensee stated it has completed a comprehensive self-assessment for all 7 milestones to ensure completeness and effectiveness. Self-assessment issues were entered into the Corrective Action Program (CAP)and addressed for program improvement. Ongoing monitoring and periodic actions provide continuing program performance monitoring.

(7) A discussion of cyber security issues pending in the licensees corrective action program (CAP).

The licensee stated that the St. Lucie CAP is used to document all cyber issues in order to trend, correct, and improve the St. Lucie CSP. The CAP database documents and tracks, from initiation to closure, all cyber security required actions, including issues identified during ongoing program assessment activities. Adverse trends are monitored for program improvement and addressed via the CAP process. Examples of issues and activities pending in the CAP were provided.

(8) A discussion of modifications completed to support the cyber security program and a discussion of pending cyber security modifications.

The licensee provided a discussion of a completed modification.

3.2 NRC Staff Evaluation The NRC staff evaluated the licensees application using the regulatory requirements and the guidance cited in Section 2.0 above.

The licensee stated that the CSP requirement regarding additional time to implement is found in CSP Section 3.1,Analyzing Digital Computer Systems and Networks Applying Cyber Security Controls. The licensee provided a list of additional activities required to implement the CSP requirement.

The licensee indicated that completion of the activities associated with the CSP, as described in Milestones 1 through 7 and completed prior to December 31, 2012, provides a high degree of protection to ensure that the most significant digital computer and communication systems and networks associated with safety, security, and emergency preparedness systems are already protected against cyber attacks. It detailed activities completed for each milestone and noted that several elements of Milestone 8 have already been implemented or will be implemented by the original Milestone 8 date of September 30, 2014. It provided details about the completed milestones and elements. On such bases, the NRC staff finds that the licensees site is much more secure after implementation of Milestones 1 through 7 because the activities the licensee completed will mitigate the most significant cyber attack vectors for the most significant CDAs.

The licensee proposed a Milestone 8 completion date of December 31, 2017. The licensee stated that changing the completion date of Milestone 8 allows for two additional refueling outages per unit and provides adequate time to complete CDA assessment, implement design modifications based on assessment results, update existing procedures and develop new procedures to complete full implementation of the CSP. The NRC staff has had extensive interaction with the nuclear industry since licensees first developed their CSP implementation schedules. Based on this interaction, the NRC staff recognizes that CDA assessment work is much more complex and resource-intensive than originally anticipated. The licensee has a large number of CDAs and underestimated the level of effort to address security controls for each of the CDAs when developing its CSP implementation schedule. The NRC staff finds that the licensees request for additional time to implement Milestone 8 is reasonable given the unanticipated complexity and scope of the work required to come into full compliance with its CSP.

The licensee stated that its methodology for prioritizing the St. Lucie CSP Milestone 8 activities is centered on considerations for safety, security, emergency preparedness, and balance-of-plant (continuityof power) consequences. The methodology is based on defense-in-depth, installed configuration of the CDA, and susceptibility to five commonly identified threat vectors.

Prioritization of CDA assessments begins with safety-related CDAs and continues through the lower priority non-safety-related CDAs. The NRC staff finds that based on the large number of digital assets described above and the limited resources with the appropriate expertise to perform these activities, the licensees methodology for prioritizing work on CDAs is appropriate.

The NRC staff further finds that the licensees request to delay final implementation of the CSP until December 31, 2017, is reasonable given the complexity of the remaining unanticipated work and the need to perform certain work, including design changes, during scheduled fuel outages.

3.3 Revision to License Condition The licensee proposed to modify the part of License Condition 3.F of Renewed Facility Operating License No. DPR-67 as follows:

St. Lucie shall fully implement and maintain in effect all provisions of the Commission-approved cyber security plan (CSP). including changes made pursuant to the authority of 10 CFR 50.90 and 10 CFR 50.54(p). The St. Lucie CSP was approved by License Amendment No. 211 as supplemented by aClarifications approved by License Amendment No. 214 and No. _____.

The licensee proposed to modify the part of License Condition 3.F of Renewed Facility Operating License NPF-16 as follows:

St. Lucie shall fully implement and maintain in effect all provisions of the Commission-approved cyber security plan (CSP). including changes made pursuant to the authority of 10 CFR 50.90 and 10 CFR 50.54(p). St. Lucie CSP was approved by License Amendment No. 160 as supplemented by aClarifications approved by License Amendment No. 164 and No. _____.

3.4 Summary of Technical Evaluation The NRC staff determines that the licensees request to delay full implementation of its CSP until December 31, 2017, is reasonable for the following reasons: (i) the licensees implementation of Milestones 1 through 7 already provides mitigation for significant cyber attack vectors for the most significant CDAs, as discussed above; (ii) the scope of the work required to come into full compliance with the CSP implementation schedule was much more complicated than anticipated and not reasonably foreseeable; and (iii) the licensee has reasonably prioritized and scheduled the work required to come into full compliance with its CSP implementation schedule.

Based on its review of the application, as supplemented, the NRC staff concludes that the licensees implementation of Milestones 1 through 7 has added additional protection which provides mitigation for significant cyber attack vectors forc the most significant CDAs, that the licensees explanation of the need for additional time is compelling, and that it is acceptable for the licensee to complete implementation of Milestone 8, full implementation of the CSP by

December 31, 2017. The NRC staff also concludes that, upon full implementation of the licensees cyber security program, the requirements of the licensees CSP and 10 CFR 73.54 will be met. Therefore, the NRC staff finds the proposed change acceptable.

The NRC staff does not regard the CSP milestone implementation dates as regulatory commitments that can be changed unilaterally by the licensee, particularly in light of the regulatory requirement at 10 CFR 73.54, that "[i]mplementation of the licensee's cyber security program must be consistent with the approved schedule." As the NRC staff explained in its letter to all operating reactor licensees dated May 9, 2011 (ADAMS Accession No. ML110980538), the implementation of the plan, including the key intermediate milestone dates and the full implementation date shall be in accordance with the implementation schedule submitted by the licensee and approved by the NRC. All subsequent changes to the NRC-approved CSP implementation schedule, thus, will require prior NRC approval as required by 10 CFR 50.90.
