1.0 INTRODUCTION

By application dated December 19, 2013, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13358A335)

Entergy Nuclear Operations Inc. (Entergy, the licensee) requested a change to the renewed facility operating license (FOL) for Vermont Yankee Nuclear Power Station (VY). The proposed change would revise the date of Cyber Security Plan (CSP) Implementation Schedule Milestone 8 and the existing license conditions in the facility operating license. Milestone 8 of the CSP implementation schedule is the full implementation of the CSP. The supplement to the application dated June 25, 2014 (ADAMS Accession No. ML14182A145), provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the U.S. Nuclear Regulatory Commission (NRC) staff's original proposed no significant hazards consideration determination as published in the Federal Register on February 27, 2014 (79 FR 11149). Portions of the letter dated December 19, 2013, contain sensitive unclassified non-safeguards information and, accordingly, those portions have been withheld from public disclosure.

2.0 REGULATORY EVALUATION

The NRC staff reviewed and approved the licensee's existing CSP implementation schedule by License Amendment No. 247 dated July 20, 2011 (ADAMS Accession No. ML11152A013), concurrent with the incorporation of the CSP into the facility's current licensing basis. The NRC staff considered the following regulatory requirements and guidance in its review of the current license amendment request to modify the existing CSP implementation schedule:

• Title 10 of the Code of Federal Regulations (1 0 CFR), Section 73.54 states: "Each [CSP] submittal must include a proposed implementation schedule.

Implementation of the licensee's cyber security program must be consistent with the approved schedule."

• The licensee's renewed facility operating license at Paragraph 3.G. includes a license condition that requires the licensee to fully implement and maintain in effect all provisions of the Commission-approved CSP.

• Amendment No. 247 dated July 20, 2011, which approved the licensee's CSP and implementation schedule, included the following statement:

The implementation of the CSP, including the key intermediate milestone dates and the full implementation date, shall be in accordance with the implementation schedule submitted by the licensee on July 16, 2010, as supplemented by letters dated February 15 and April 4, 2011, and approved by the NRC staff with this license amendment.

All subsequent changes to the NRC-approved CSP implementation schedule will require prior NRC approval pursuant to 10 CFR 50.90.

• In a publically available NRC memorandum dated October 24, 2013 (ADAMS Accession No. ML13295A467), the NRC staff listed criteria to consider during evaluations of licensees' requests to postpone their cyber security program implementation date (commonly known as Milestone 8). 3.0 TECHNICAL EVALUATION Amendment No. 247 to Renewed FOL DPR-28 for VY was issued on July 20, 2011. As part of that amendment, the NRC staff approved the licensee's CSP implementation schedule, as discussed in the safety evaluation issued with the amendment.

The licensee's implementation schedule was based on a template prepared by NEI (ADAMS Accession No. ML110600218), which the NRC staff had previously found acceptable for use in developing CSP implementation schedules.

The licensee's CSP implementation schedule 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 deterministic one-way 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 as per "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. 3.1 Licensee's Proposed Change Currently, Milestone 8 of the VY CSP requires Entergy to fully implement the CSP by December 15, 2014. In its December 19, 2013, application, Entergy proposed to change the Milestone 8 completion date to June 30, 2016. 3.2 NRC Staff Evaluation The purpose of the cyber security implementation schedule is for licensees to demonstrate ongoing implementation of their cyber security program prior to full implementation (i.e., Milestone 8). The licensee completed the first seven milestones by December 31, 2012. These milestones include establishing a CSAT, identifying CSs and CDAs, installing deterministic way devices between defensive levels, implementing access control for portable and mobile devices, implementing methods to observe and identify obvious cyber related tampering, and conducting ongoing monitoring and assessment activities for target set CDAs. In aggregate, these interim milestones demonstrate ongoing implementation of the cyber security program. On October 24, 2013, the staff published review criteria for evaluating requests to revise Milestone 8 implementation dates. The licensee's application was received after this guidance was published, and addresses all the included criteria.

The review criteria for Milestone 8 extension requests takes into account the licensees' ongoing implementation of the cyber security program through milestones 1 through 7. The criteria which the licensee addressed are: (1) Identification of the specific requirement or requirements of the cyber security plan that the licensee needs additional time to implement.

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

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

(4) An evaluation of the impact that the additional time to implement the requirements will have on the effectiveness of the licensee's overall cyber security program in the context of milestones already completed.

(5) A description of the licensee's methodology for prioritizing completion of work for critical digital assets associated with significant safety, security, or emergency preparedness consequences and with reactivity effects in the balance of plant. (6) A discussion of the licensee's cyber security program performance up to the date of the license amendment request. (7) A discussion of cyber security issues pending in the licensee's corrective action program. (8) A discussion of modifications completed to support the cyber security program and a discussion of pending cyber security modifications.

The licensee provided information pertinent to each criterion.

It is below. (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 requirements of the CSP that it needed additional time to implement are Section 3, Analyzing Digital Computer Systems and Networks and Section 4, Establishing, Implementing and Maintaining the Cyber Security Program. It further noted that these sections describe requirements for application and maintenance of cyber security controls and described the process of addressing security controls.

The licensee also noted specific activities needing additional time including:

final determination of the exact scope of CDAs that will remain subsequent to the final permanent shut-down and defueling of VY, scheduled to commence in December 2014; determining the need for a specific security feature; and change management associated with approximately 40 procedure changes. It also described time needed for additional physical controls for CDAs outside the security protected area. (2) Detailed justification that describes the reason the licensee requires additional time to implement the specific requirement or requirements identified.

The licensee stated the cyber security assessment process is presently projected to be completed by the second quarter of 2014. Since the number of CDAs and existing procedures is in the hundreds and the number of individual cyber security control attributes is also in the hundreds the total of physical, logical and programmatic changes required constitutes a significant project involving plant components and systems and substantial planning and resources.

With this analysis concluding in the second quarter of 2014, it was concluded that insufficient time is left to complete modification and change management planning activities by December 15, 2014. Further the licensee intends to complete planning for the specific security feature mentioned in 1) above in 2014 and implement it in the following 18 months. (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 June 30, 2016. (4) An evaluation of the impact that the additional time to implement the requirements will have on the effectiveness of the licensee's overall cyber security program in the context of milestones already completed.

The licensee indicated the impact of the requested additional implementation time on the effectiveness of the overall cyber security program is very low. The milestones already completed have resulted in a high degree of protection of safety-related, important-to-safety, and security CDAs against common threat vectors. Additionally, extensive physical and administrative measures are already in place for CDAs because they are plant components, pursuant to the Physical Security Plan and Technical Specification Requirements.

It then briefly described how it had implemented the various milestones.

The licensee supplemented its application to clarify that various milestones had been completed by the due date of December 31, 2012, and that the extension request has no impact on these milestone activities. 5) A description of the licensee's methodology for prioritizing completion of work for critical digital assets associated with significant safety, security, or emergency preparedness consequences and with reactivity effects in the balance of plant. The licensee stated, because CDAs are plant components, prioritization follows the normal work management process that places the highest priority on apparent conditions adverse to quality in system, structure, and component design function and related to factors such as safety risk and nuclear depth, as well as threats to continuity of electric power generation.

6) A discussion of the licensee's cyber security program performance up to the date of the license amendment request. The licensee stated there has been no identified compromise of SSEP functions by cyber means at any Entergy plant. It noted its experience with the scanning of portable devices. It also noted a formal Quality Assurance (QA) audit in the last quarter of 2013 that included review of the cyber security program implementation.

There were no significant findings related to overall cyber security program performance and effectiveness.

7) A discussion of cyber security issues pending in the licensee's corrective action program (CAP). The licensee stated there are presently no significant (constituting a threat to a CDA via cyber means or calling into question program effectiveness) nuclear cyber security issues pending in the CAP. Several non-significant issues identified during the Quality Assurance audit described above have been entered into CAP. Additionally, when the July 1, 2013 internal NRC memorandum (ADAMS Accession No. ML13178A203) was shared with Entergy the actions described regarding cyber security Interim Milestone 4 were entered into CAP for evaluation by the CSAT. Final actions regarding some program activities are pending. 8) A discussion of modifications completed to support the cyber security program and a discussion of pending cyber security modifications.

The NRC staff has evaluated the licensee's application addressing the above criteria.

The NRC staff's evaluation is below. The NRC staff agrees that implementation of CSP Sections 3 and 4 requires the extensive actions the licensee noted. The NRC staff acknowledges implementation issues with large numbers of CDAs and the need to address many security control attributes for each. Based on the information provided by the licensee in its application, the NRC staff concludes that VY would not be able to fully implement its CSP by December 15, 2014. In conclusion, the NRC staff finds the licensee's explanation of the need for additional time compelling.

The NRC staff concludes the licensee progress toward full implementation is reasonable and that impact of the requested additional implementation time on the effectiveness of the overall cyber security program is being effectively managed. The NRC staff finds the licensee's methodology for prioritizing completion of work for CDAs is appropriate and conservative.

The NRC staff agrees that activities described by the licensee in its LAR provide significant protection against cyber attacks. The NRC staff concludes that the licensee is using the quality tools at its disposal to verify the effectiveness of the cyber security program and that the licensee is using its corrective action program to track issues for the cyber security program. As requested by Criteria 8, the licensee discussed completed modifications and pending modifications.

The NRC staff has reviewed these discussions of the completed and pending modifications to address Criteria 1 through 7 and concluded, as discussed in the LAR, these modifications support the full implementation of the CSP. 3.3 Revision to License Condition By letter dated December 19, 2013, the licensee proposed to modify Paragraph 3.G. of Renewed FOL No. DPR-28, which provides a license condition requiring the licensees to fully implement and maintain in effect all provisions of the NRC-approved CSP. The second paragraph of the license condition in Paragraph 3.G. of Renewed FOL No. DPR-28 for VY is modified as follows: "Entergy Nuclear Operations, Inc. 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).

Entergy Nuclear Operations, Inc. CSP was approved by License Amendment No. 247, as supplemented by changes approved by License Amendment Nos. 251 and 259." 3.4 Summary Based on its review of the licensee's submissions, the NRC staff concludes that the proposed change to the full implementation date of Milestone 8 of the licensee's CSP implementation schedule is acceptable.

The NRC staff also concludes that, upon full implementation of the licensee's cyber security program, the requirements of the licensee's 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 pursuant in 10 CFR 50.90.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Vermont State official was notified of the proposed issuance of the amendment.

The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION This amendment relates solely to safeguards matters and does not involve any significant construction impacts. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(12).

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

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 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.
