SUMMARY
DESCRIPTION The proposed license amendment request includes the proposed PPL:'Susquehanna, LLC Cyber Security Plan (the Plan), an Implementation Schedule, and a proposed sentence to be added to the existing Facility Operating License (FOL) Physical Protection license condition for Unit 1 and Unit 2.
- 2. DETAILED DESCRIPTION The proposed license amendment request includes three parts: the proposed Plan, an Implementation Schedule, and a proposed sentence to be added to the existing FOL Physical Protection license condition to require PPL Susquehanna to fully implement and maintain in effect all provisions of the Commission approved cyber security plan as required by 10 CFR §73.54. FederalRegister notice issued the final ':rule that amended 10CFR Part 73. The regulations in 10 CFR §73.54, "Protection of digital computer and communication systems and networks," establish the requirements for a cyber security program. This regulation specifically requires each licensee currently licensed to operate a nuclear power plant under Part 50 of this chapter to submit a cyber security plan that satisfies the requirements of the Rule. Each submittal must include a proposed implementation schedule and implementation of the licensee's cyber security program must be consistent with the approved schedule. The background for this application is addressed by the NRC Notice of Availability published on March 27, 2009, 74 FR 13926 (Reference 1).
- 3. TECHNICAL EVALUATION FederalRegister notice 74 FR 13926 issued the final rule that amended 10 CFR Part 73.
Cyber security requirements are codified as new §73.54 and are designed to provide high assurance that digital computer and communication systems and networks are adequately protected against cyber attacks up to and including the design basis threat established by
§ 73.1 (a)( 1(v). These requirements are substantial improvements upon the requirements imposed by EA-02-026 (Reference 2).
Enclosure 1 to PLA-6628 Page 2 of 5 NRC issued pre-decisional Regulatory Guide 5.71, "Cyber Security Programs for Nuclear Facilities" which provides an approach the NRC staff deems acceptable for complying with the Commission's regulations for protecting digital computers, communications systems, and networks. NEI 08-09, "Cyber Security Plan Template".has been developed by NEI (Reference 3) for use by licensees in development of their own cyber security plans.
This license amendment request includes the proposed Cyber Security Plan (Enclosure 3) that conforms to the template provided in NEI 08-09, Revision 6 with the exception of the definition of "cyber attack" that has been modified to align with agreements reached with the NRC staff. In addition, the license amendment request includes the proposed change to the existing Unit 1 and Unit 2 FOL license condition for "Physical Protection" (Enclosure 1, Attachments 1 and 2). Finally, the license amendment request contains the proposed Implementation Schedule (Enclosure 2) as required by 10 CFR §73.54.
- 4. REGULATORY EVALUATION 4.1 Applicable Regulatory Requirements / Criteria This license amendment request is submitted pursuant to 10 CFR §73.54 which requires licensees currently licensed to operate a nuclear power plant under 10 CFR Part 50 to submit a Cyber Security Plan as specified in §50.4 and §50.90.
4.2 Significant Hazards Consideration PPL has evaluated the proposed changes using the criteria in 10 CFR 50.92 and has determined that the proposed changes do not involve a significant hazards consideration.
An analysis of the issue of no significant hazards consideration is presented below.
The proposed license amendment request includes three parts: the proposed PPL Susquehanna, LLC Cyber Security Plan, an Implementation Schedule, and a proposed sentence to be added to the existing Facility Operating License (FOL) Physical Protection license condition to require PPL Susquehanna Units 1 and 2 to fully implement and maintain in effect all provisions of the Commission-approved cyber security plan as required by 10 CFR §73.54. The regulations in 10 CFR §73.54, "Protection of digital computer and communication systems and networks," establish the requirements for a cyber security program.
The Cyber Security Plan conforms to the template provided in NEI 08-09, Revision 6, with the exception that the definition of "cyber attacks" has been modified to align with agreements reached with the NRC staff. The plan also provides a description of how the
Enclosure 1 to PLA-6628 Page 3 of 5 requirements of 10 CFR §73.54 will be implemented at PPL Susquehanna Units 1 and 2 in order to protect the health and safety of the public from radiological sabotage as a result of a cyber attack. The Cyber Security Plan establishes the licensing basis for the PPL Cyber Security Program for Susquehanna Units 1 and 2. The Cyber Security Plan establishes how to achieve high assurance that nuclear power plant digital computer and communication systems and networks associated with the following are adequately protected against cyber attacks up to and including the design basis threat:
- 1. Safety-related and important-to-safety functions,
- 2. Security functions,
- 3. Emergency preparedness functions including offsite communications, and
- 4. Support systems and equipment which, if compromised, would adversely impact safety, security, or emergency preparedness functions.
(1) Does the proposedamendment involve a significant increasein the probability or consequences of an accidentpreviously evaluated?
Response: No.
The proposed amendment incorporates a new requirement in the PPL Susquehanna Units 1 and 2 FOL to implement and maintain a Cyber Security Plan as part of the facility's overall program for physical protection. Inclusion of the Cyber Security Plan in the FOL itself does not involve any modifications to the safety-related structures, systems or components (SSCs). Rather, the Cyber Security Plan describes how the requirements of 10 CFR 73.54 are to be implemented to identify, evaluate, and mitigate cyber attacks up to and including the design basis cyber attack threat, thereby achieving high assurance that the facility's digital computer and communications systems and networks are protected from cyber attacks. The Cyber Security Plan will not alter previously evaluated Final Safety Analysis Report (FSAR) design basis accident analysis assumptions, add any accident initiators, or affect the function of the plant safety-related SSCs as to how they are operated, maintained, modified, tested, or inspected. Therefore, the proposed amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated.
(2) Does the proposedamendment create the possibility of a new or different kind of accidentfrom any accidentpreviously evaluated?
Response: No.
This proposed amendment provides assurance that safety-related SSCs are protected from cyber attacks. Implementation of 10 CFR 73.54 and the inclusion
Enclosure 1 to PLA-6628 Page 4 of 5 of a plan in the PPL Susquehanna Units 1 and 2 FOL do not result in the need for any new or different FSAR design basis accident analysis. The inclusion does not introduce new equipment that could create a new or different kind of accident, and no new equipment failure modes are created. The inclusion of the Cyber Security Plan also does not affect the function of any safety-related SSC as to how they are operated, maintained, modified, tested or inspected. As a result, no new accident scenarios, failure mechanisms, or limiting single failures are introduced as a result of this proposed amendment. Therefore, the proposed amendment does not create a possibility for an accident of a new or different type than those previously evaluated.
(3) Does the proposedamendment involve a significantreduction in a margin of safety?
Response: No.
The margin of safety is associated with the confidence in the ability of the fission product barriers (i.e., fuel cladding, reactor coolant pressure boundary, and containment structure) to limit the level of radiation to the public. The proposed amendment would not alter the way safety-related SSCs function and would not alter the way PPL Susquehanna Units 1 and 2 are operated. The amendment provides assurance that safety-related SSCs are protected from cyber attacks. The proposed amendment would not introduce any new uncertainties or change any existing uncertainties associated with the design basis or any safety limit. The proposed amendment would have no impact on the structural integrity of the fuel cladding, reactor coolant pressure boundary, or containment structure. Based on the above considerations, the proposed amendment would not degrade the confidence in the ability of the fission product barriers to limit the level of radiation to the public. Therefore, the proposed change does not involve a significant reduction in a margin of safety.
4.3 Conclusion In conclusion, based on the considerations discussed above: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner; (2) such activities will be conducted in compliance with the Commission's regulations; and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

Renewed Operating License No. NPF-22 to PLA-6628 PPL Susquehanna, LLC Cyber Security Plan Implementation Schedule
Enclosure 2 to PLA-6628 Page 1 of 4 PPL SUSQUEHANNA, LLC Cyber Security Plan Implementation Schedule Generic RAI Question # 29 includes reference to previous regulatory guidance and industry initiatives related to cyber security. As referenced, current industry guidance for cyber security is described in NEI 04-04, Cyber Security Programfor Power Reactors. H-wever, the scope of requirements in the NRC accepted implementation guidance contained in NEI 08-09 revision 6 are significantly greater than the previously implemented cyber security program. The defensive model design requirements, the new digital asset assessment methodology and the resultant digital asset remediation actions will require a significant expenditure of labor resources. As referenced in the Generic RAI Question # 29, PPL Susquehanna, LLC is also required to implement a separate cyber security program in accordance with the NERC Critical Infrastructure Protection Standards. While the timeframe for implementation is shorter for the NERC regulation as described in the RAI question, the NERC cyber security methodology is different from the NRC Rule requirements. The NERC requirements are based on a logical risk based assessment process while the NRC Rule 73.54 requires a deterministic cyber securityassessmentmethodology.
In light of the extensive work associated with implementation of these two new regulations, PPL Susquehanna, LLC has developed a prioritized approach to establish the NRC Rule 73.54 implementation schedule. PPL Susquehanna, LLC realizes the importance of deploying a boundary control communication barrier to protect the most critical SSEP functions. One major activity is the deployment of boundary control communication barrier to ensure protection from remote attacks on plant systems. While the deployment of the boundary control barrier is critical to protection from external cyber threats, it also impacts remote access to plant data systems by authorized personnel. This elimination of remote access will require Licensees to develop and implement a detailed change management plan.
Another major activity is the performance of individual critical digital asset (CDA) assessments to identify individual asset security control remediation actions.
Programs and procedures are being developed to implement the programmatic requirements of the regulation. The cyber security assessment teams are also being established for execution of program requirements. These teams are required to have extensive knowledge of plant systems and cyber security control technology. A comprehensive training program will be required to ensure competent personnel for program execution.
Following are the Cyber Security implementation milestones that have been developed based on the sample listing of milestones provided with the NRC December 2009 implementation schedule guidance:

Develop Cyber Security 6/30/2011 The Defensive Strategy expands upon the high level model in the Cyber Securty Plan and requires Defensive Strategy (i.e., assessment of existing site and corporate policies, comparison to new requirements, revisions as defensive model) required, and communication to plant personnel.
By the completion date, the following will be performed:
- Documenting the defense-in-depth architecture and defensive strategy;
- Revisions to existing defensive strategy policies will be implemented and communicated; and
- Planning the implementation of the defense-in-depth architecture.
Implement cyber security 6/30/2012 for The implementation of communication barrers protects the most critical SSEP functions from remote defense-in-depth architecture deterministic attacks on our plant systems. While the deployment of the barriers is critical to protection from external isolation devices. cyber threats, it also prevents remote access to core monitoring and plant data systems for reactor 6/30/2013 for other engineers and other plant staff. This elimination of remote access to core monitoring systems requires boundary control the development and execution of a detailed change management plan to ensure continued safe devices *operation of the plants.
Enclosure 2 to PLA-6628 Page 3 of 4 PPL SUSQUEHANNA, LLC Vendors may be required to develop software revisions to support the model. The modification will be developed, prioritized and scheduled. Since software must be updated on and data retrieved from isolated systems, a method of patching, updating and scanning isolated devices will be developed.
By the completion date, the following will be performed:
0 Installation of boundary layer control devices to implement defensive layer boundaries.
Establish Cyber Security 12/31/2013 The implementation of the cyber security program is expected to require policy/procedure development Program policies/procedures and/or upgrades for nearly every plant department. The procedural development for the cyber security program requirements and all of the individual security controls will be far-reaching. Many of the security controls will require development of the technical processes for implementing the control in a nuclear plant environment including development of new procedures for surveillances, periodic monitoring and reviews- Prikeedireidevel6pment will begin early in the implementation of the program and continue until the specified completion date.
By the completion date, the following will be performed:
- Policies/procedures will be updated to establish Cyber Security Program;
- The Cyber Security Assessment Procedure will be issued; and
- New policies/procedures or revision of existing policies/procedures in areas impacted by cyber security requirements will be develop and implemented.
Perform and document the 12/31/2013 Based on the existing cyber security program, it is known that the number of digital assets requiring cyber security assessment assessment is extensive. As previously discussed, the CDA assessment methodology required for this described in the Cyber regulation is extremely rigorous and deterministic. The completion of these assessments will require a Security Plan significant commitment of resources. The assessments will not begin prior to having a fully established CSAT and the required procedures.
Performing the assessments will require participation of multiple disciplines and involve document reviews, system configuration evaluation, physical walk downs or electronic verification of every communication pathway for each CDA, and documentation of results. These tasks will need to be
