UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 220 TO FACILITY OPERATING LICENSE NO. DPR-80 AND AMENDMENT NO. 222 TO FACILITY OPERATING LICENSE NO. DPR-82 PACIFIC GAS AND ELECTRIC COMPANY DIABLO CANYON POWER PLANT, UNIT NOS. 1 AND 2 DOCKET NOS. 50-275 AND 50-323

1.0 INTRODUCTION

By letter dated October 17, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14290A603), as supplemented by letter dated February 19, 2015 (ADAMS Accession No. ML15050A437), Pacific Gas and Electric Company (PG&E, the licensee) submitted a license amendment request (LAA) to revise the Cyber Security Plan (CSP) Milestone h (commonly known as Milestone 8) full implementation schedule completion date from December 31, 2015, to December 31, 2017, for Diablo Canyon Power Plant (DCPP),

Unit Nos. 1 and 2. The supplemental letter dated February 19, 2015, 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 Registeron April 7, 2015 (80 FR 18659).

2.0 REGULATORY EVALUATION

The NRC staff reviewed and approved the licensee's existing CSP implementation schedule for DCPP Unit Nos. 1 and 2 by License Amendment Nos. 210 and 212, respectively, dated July 15, 2011 (ADAMS Accession No. ML111640274). 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 1 O of the Code of Federal Regulations (10 CFR), Section 73.54 states, in part: "Each [CSP] submittal must include a proposed implementation schedule.

Implementation of the licensee's CSP must be consistent with the approved schedule."

The licensee's facility operating licenses include license conditions that require the licensee to fully implement and maintain in effect all provisions of the Commission-approved CSP.

In a publicly-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 CSP implementation date.

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 "[l]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. MU 10980538), 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 NRG-approved CSP implementation schedule, thus, will require prior NRC approval as required by 10 CFR 50.90.

3.0 TECHNICAL EVALUATION

3.1 Background

Amendment No. 210 to Facility Operating License (FOL) DPR-80 and Amendment No. 212 to FOL DPR-82 for DCPP Units 1 and 2, respectively, were issued on July 15, 2011 (ADAMS Accession No. ML111640274). The NRC staff approved the licensee's CSP implementation schedule, as discussed in the safety evaluation issued with the amendments. The implementation schedule had been submitted by the licensee based on a template prepared by the Nuclear Energy Institute (ADAMS Accession No. ML110600218), which the NRC staff found acceptable for licensees to use to develop their CSP implementation schedules (ADAMS Accession No. ML110070348). The licensee's proposed implementation schedule for the CSP identified completion dates and bases for the following eight milestones:

a)

Establish the Cyber Security Assessment Team (CSAT};

b)

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

c)

Install a deterministic one-way device between lower level devices and higher level devices; d)

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

e)

Implement observation and identification of obvious cyber related tampering to existing insider mitigation rounds by incorporating the appropriate elements; f)

Identify, document, and implement technical 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; g)

Commence ongoing monitoring and assessment activities for those target set CDAs whose security controls have been implemented; h)

Full implementation of the CSP for all safety, security and emergency preparedness functions.

3.2 Proposed Operating License Changes In the LAA dated October 17, 2014, the licensee proposed the following change to license conditions:

Current Paragraph 2.E of FOL No. DPR-80 for DCPP, Unit No. 1 states:

PG&E 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 PG&E CSP was approved by License Amendment No. 210.

Revised Paragraph 2.E of FOL No. DPR-80 for DCPP, Unit No. 1 would state:

PG&E 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 1 O CFR 50.90 and 10 CFR 50.54(p). The PG&E CSP was approved by License Amendment No. 210, as supplemented by a change approved by License Amendment No. 220.

Current Paragraph 2.E of FOL No. DPR-82 for DCPP, Unit No. 2 states:

PG&E 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 1 O CFR 50.90 and 10 CFR 50.54(p). The PG&E CSP was approved by License Amendment No. 212.

Revised Paragraph 2.E of FOL No. DPR-82 for DCPP, Unit No. 2 would state:

PG&E 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 1 O CFR 50.90 and 1 O CFR 50.54(p). The PG&E CSP was approved by License Amendment No. 212, as supplemented by a change approved by License Amendment No. 222.

3.3 Proposed Milestone h Change Currently, Milestone h of the DCPP CSP requires the licensee to fully implement the CSP by December 31, 2015. In its October 17, 2014, application, and February 19, 2015, supplement, PG&E proposed to change the Milestone h completion date to December 31, 2017.

3.4

NRC Staff Evaluation

The cyber security implementation schedule demonstrates the licensee's ongoing implementation of its CSP prior to full implementation. For DCPP, the date for full implementation is specified by Milestone h. CSP implementation activities include establishing a CSAT, identifying CSs and CDAs, installing deterministic one-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 their aggregate, the interim milestones demonstrate ongoing implementation of the CSP.

The importance of ongoing implementation is reflected in the NRC staff's October 24, 2013, guidance for considering request~ to postpone the CSP full implementation date. The criteria in the guidance 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 [Milestone h for DCPP] 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 CSP 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 consequences and with reactivity effects in the balance of plant.

6)

A discussion of the licensee's CSP 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 CSP and a discussion of

. pending cyber security modifications.

The licensee submitted its application on October 17, 2014, after the NRC staff issued the guidance. The licensee's application addressed each of the criteria in the guidance. The NRC staff has evaluated the licensee's application addressing the above criteria in its submittal dated October 17, 2014, and its February 19, 2015, supplement. The NRC staff's evaluation is below, numbered as the criteria are 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 requirement of the CSP that it needs additional time to implement is CSP Section 3.1, Analyzing Digital Computer Systems and Networks and Applying Cyber Security Controls. The licensee identified the challenges to completing implementation of the CSP requirement.

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

The licensee noted that there are ongoing issues that need resolution prior to completing implementation of CSP Section 3.1. These include CDA assessment; remediation activities; change management; and training on new processes, procedures and programs. The licensee stated it is experiencing major challenges with full implementation of Milestone h. It noted a significant effort associated with documentation of CDA assessment and analysis. More than 600 security controls must be addressed for each of approximately 2,300 CDAs. The rate of completion of CDA assessment does not support Milestone h completion within the current full implementation date. The licensee then stated DCPP underestimated the level of effort necessary to address security controls using the deterministic criteria in Section 3.1.6 of CSP.

The NRC staff acknowledges implementation issues with large numbers of CDAs and the need to address many controls for each. Based on the information provided by the license.e in its application, the NRC staff concludes that DCPP would not be able to fully implement its CSP by December 31, 2015. The staff recognizes that CDA assessment work is resource intensive and that the licensee has a large number of CDAs. The staff agrees remediation activities must be carefully considered. The staff understands that CSP implementation has created change management challenges as it has impacted many aspects of the licensee's plant processes including maintenance, engineering, and procurement. The staff understands that CSP implementation has affected longstanding training schedules. Based on the above, the NRC staff concludes that the licensee's explanation of the need for additional time is justified, given the unanticipated complexity and scope of the work required to come into full compliance with its CSP.

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

The licensee proposed a Milestone h completion date of December 31, 2017, and stated the revised Milestone h date is necessary to perform CDA assessments, initiate design modifications based on assessment results, update existing procedures, and develop new program procedures to complete full implementation of the CSP. Additionally, it noted the revised completion date will provide adequate time to plan and schedule the implementation of design changes identified as a result of the CDA assessments.

Based on the license's application, the NRC staff concludes that delaying final implementation of the CSP will provide an opportunity for the licensee to complete the large volume of work in an orderly manner and avoid rework.

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

The licensee indicated it was secure based on the CSP activities already completed, and that PG&E will continue to ensure, that digital computer and communication systems and networks are protected adequately against cyber-attacks during implementation of the remainder of the program by the proposed Milestone h date. It then detailed the activities completed in each of the milestones a through g. The activities address significant cyber-attack vectors and applied controls to the most significant CDAs.

The NRC staff concludes the licensee provided sufficient justification that the additional time requested will not adversely impact the overall effectiveness of the CSP and is, therefore, acceptable.

5) A description of the licensee's 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 Milestone h activities is centered on considerations for safety, security, emergency preparedness (EP), and balance of plant (BOP) consequences. The methodology is based on defense-in-depth, installed configuration of the CDA and susceptibility to commonly identified threat vectors. Prioritization for CDA assessment begins with safety-related CDAs and continues through lower priority non-safety and EP CDAs.

The NRC staff concludes that the licensee's methodology for prioritizing work on CDAs is sufficiently justified and is, therefore, acceptable.

6) A discussion of the licensee's CSP performance up to the date of the license amendment request.

The licensee stated that Milestone a through g activities and other actions implemented by December 31, 2012, provide a high degree of protection against cyber security related attacks.

The licensee discussed its implementation of various milestones that provide program controls and modifications for protection to significant CDAs from common attack vectors. Ongoing licensee Quality Assurance surveillances have concluded that the licensee has an effective program. The NRC staff's inspection issues were entered into the corrective action program (CAP) and are being addressed for program improvement. Ongoing monitoring and time-based periodic actions provide continuous program performance monitoring.

The NRC staff concludes that the licensee's completion of Milestones a through g provides assurance of protection against cyber-attacks. The NRC staff concludes that the licensee has sufficient quality tools at its disposal to verify the effectiveness of the CSP and to address program issues in its CAP and is, therefore, acceptable.

7) A discussion of cyber security issues pending in the licensee's corrective action program.

The licensee stated that the DCPP CAP is used to document all cyber security issues in order to trend, correct, and improve DCPP's CSP. The CAP database documents and tracks, from initiation through closure, 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. The licensee listed cyber security program issues and activities pending in the CAP.

The NRC staff concludes that the examples provided evidence of sufficient program development for implementation of an effective CAP for the CSP and is, therefore, acceptable.

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

The licensee provided a discussion of completed modifications and pending modifications.

These are consistent with the discussions provided above. The licensee's completed and planned implementation actions provide 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 10 CFR 73.1 (a)(1 )(v), until the full program is implemented by the proposed date. Therefore, the NRC staff concludes that the lipensee's request to delay final implementation of the CSP until December 31, 2017, is acceptable.

3.5 NRC Staff Conclusion

Based on its review of the licensee's submissions, the NRC staff concludes that implementation of Milestones a through g provides significant protection against cyber-attacks; that the licensee's explanation of the need for additional time is compelling, and that it is acceptable for DC~P to complete Milestone h (full implementation of the CSP) by December 31, 2017. The NRC staff has reasonable assurance that full implementation of the CSP by December 31, 2017, will provide adequate protection of the public health and safety and the common defense and security. The NRC staff also concludes that, upon full implementation of the licensee's CSP, the requirements of the licensee's CSP and 10 CFR 73.54 will be met.

Therefore, the NRC staff concludes that the proposed change is acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the appropriate California State official was notified of the proposed issuance of the amendments. The State official had no comments.

5.0

  • ENVIRONMENTAL CONSIDERATION The amendments relate solely to safeguards matters and do not involve any significant construction impacts. The amendments are an administrative change to extend the date by which the licensee must have its CSP fully implemented. Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 1 O 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 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 Commission's 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.
