SUMMARY
DESCRIPTION The proposed license amendment request (LAR) includes the proposed Diablo Canyon Power Plant (DCPP) Cyber Security Plan (Plan), an Implementation Schedule, and a proposed sentence to be added to the existing FOL Physical Protection license condition.
2.0 DETAILED DESCRIPTION The proposed LAR 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 PG&E to fully implement and maintain in effect all provisions of the Commission-approved Plan as required by 10 CFR 73.54, "Protection of Digital Computer and Communication Systems and Networks." The regulations in 10 CFR 73.54 establish the requirements for a cyber security program (Program). This regulation specifically requires each licensee currently licensed to operate a nuclear power plant under Part 50 of this chapter to submit a Plan that satisfies the requirements of the Rule. Each submittal must include a proposed implementation schedule and implementation of the licensee's 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).
3.0 TECHNICAL EVALUATION
FederalRegister notice 74 FR 13926 issued the final'rule that amended 10 CFR 73. Cyber security requirements are codified as new 10 CFR 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 (DBT) established by 10 CFR 73.1(a)(1)(v).
These requirements are substantial improvements upon the requirements imposed by EA-02-026 (Reference 2).'
This LAR includes the proposed Plan (Enclosure 3) that is consistent with the template provided in industry document NEI 08-09, "Cyber Security Plan for Nuclear Power Reactors," Revision 6, dated April 2010. Based on a technical review of the document, the NRC staff concluded that the template provided in NEI 08-09, Revision 6 would be acceptable for use by licensees to comply with the requirements of 10 CFR 73.54 with the exception of the definition of "cyber attack" (Reference 3). The NRC staff reviewed and approved by letter, a definition for "cyber attack" to be used in submissions based on NEI 08-09, Revision 6 (Reference 4). The DCPP submittal uses the definition of "cyber attack" included in Reference 4.
In addition the LAR includes the proposed change to the existing FOL condition for "Physical Protection" (Attachment 1). Finally, the LAR contains the proposed 1
Enclosure 1 PG&E Letter DCL-10-087 Implementation Schedule (Enclosure 2) as required by 10 CFR 73.54.
4.0 REGULATORY EVALUATION
4.1 APPLICABLE REGULATORY REQUIREMENTS / CRITERIA This LAR 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 Plan as specified in 10 CFR 50.4 and 10 CFR 50.90.
4.2 SIGNIFICANT HAZARDS CONSIDERATION Pacific Gas and Electric Company (PG&E) has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
The proposed amendment incorporates a new requirement in the Facility Operating License (FOL) to implement and maintain a Cyber Security Plan (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 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. Any plant modifications necessary to implement the Plan will be evaluated pursuant to 10 CFR 50.59 to assure they will not alter previously evaluated 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. Further amendments to the operating licenses will be pursued as necessary based on the results of these evaluations.
2
Enclosure 1 PG&E Letter DCL-10-087 Therefore, the proposed amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the, proposed amendment create the possibility of a new or different accident from any accident previously 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 of a plan in the FOL do not result in the need of any new or different FSAR design basis accident analysis. As noted in response to question 1, any plant modifications necessary to implement the Plan will be evaluated pursuant to 10 CFR 50.59 to assure they do not introduce new equipment that could create a new or different kind of accident, and no new equipment failure modes are created. Further amendments to the operating licenses will be pursued as necessary based on the results of these evaluations.
As a result, no new accident scenarios, failure mechanisms, or limiting single failures will be introduced as a result of this proposed amendment.
Therefore, the proposed change does not create the possibility of a new or different accident from any accident previously evaluated.
- 3. Does the proposed amendment involve a significant reduction 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 any safety-related SSC functions and would not alter the way the plant is 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 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.
3
Enclosure 1 PG&E Letter DCL-10-087 Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based on the above, PG&E concludes that the proposed amendment does not involve a significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and accordingly, a finding of "no significant hazards consideration" is justified.
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.
5.0 ENVIRONMENTAL CONSIDERATION
The proposed amendment establishes the licensing basis for a Program for DCPP and will be a part of the Physical Security Plan.' This proposed amendment will not involve any significant construction impacts. PG&E has evaluated the proposed amendment and has determined that the proposed amendment does not involve: (1) a significant hazards consideration, (2) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (3) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
