UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 January 9, 2017

MEMORANDUM TO: Biweekly Notice Coordinator FROM: John B. Hickman, Project Manager /RA/ Reactor Decommissioning Branch Division of Decommissioning, Uranium Recovery, and Waste Programs Office of Nuclear Material Safety and Safeguards

SUBJECT:

REQUEST FOR PUBLICATION IN BIWEEKLY FEDERAL REGISTER NOTICE - NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE, PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION, AND OPPORTUNITY FOR A HEARING (CAC NO. L53125)

Duke Energy Florida, Inc., et al., Docket No. 50-302, Crystal River Unit 3 Nuclear Generating Plant (CR-3), Citrus County, Florida Date of amendment request: March 31, 2016. A publicly available version is in the Agencywide Document Access Management System under Accession No. ML16091A308. Description of amendment request: The amendment would revise the Physical Protection license condition for the facility operating license to reflect a change to the Cyber Security Plan (CSP) implementation schedule. Specifically, the completion date for Milestone 8 is proposed to be changed from December 31, 2017 to December 31, 2018.

Basis for proposed no significant hazards consideration determination: As required by Title 10 of the Code of Federal Regulations (10 CFR) 50.91(a), the licensee has provided its analysis of the issue of no significant hazards consideration, which is presented below:

Biweekly Notice Coordinator 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

No.

The proposed one year extension to the Cyber Security Plan implementation schedule for Milestone 8 does not alter the Fuel Handling Accident analysis, add any initiators, or affect the function of plant systems or the manner in which systems are operated, maintained, modified, tested, or inspected. The proposed change does not require any plant modifications that affect the performance capability of the structures, systems, and components relied upon to mitigate the consequences of postulated accidents and have no impact on the probability or consequences of an accident previously evaluated.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated. 2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

No.

The proposed change to the Cyber Security Plan implementation schedule for Milestone 8 does not alter accident analysis assumptions, add any initiators, or affect the function of plant systems or the manner in which systems are operated, maintained, modified, tested, or inspected. The proposed change does not require any plant modifications that affect the performance capability of the structures, systems, and components relied upon to mitigate the consequences of postulated accidents and does not create the possibility of a new or different kind of accident from any accident previously evaluated.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated. 3. Does the proposed amendment involve a significant reduction in a margin of safety?

No.

Plant safety margins are established through limiting conditions for operation and safety analysis described in the FSAR. The proposed change revises the Cyber Security Plan implementation schedule. The proposed Cyber Milestone 8 schedule change does not involve a significant reduction in a margin of safety because the proposed change does not involve changes to the initial conditions contributing to accident severity or consequences, or reduce response or mitigation capabilities. Because there is no change to these established safety margins as result of this change, the proposed change does not involve a significant reduction in a margin of safety.

Biweekly Notice Coordinator Therefore, the proposed change does not involve a significant reduction in a margin of safety.

The U.S Nuclear Regulatory Commission (NRC) staff has reviewed the licensee's analysis and, based on this review, it appears that the three standards of 50.92(c) are satisfied. Therefore, the NRC staff proposes to determine that the amendment request involves no significant hazards consideration. Attorney for licensee: Lara S. Nichols, 550 South Tryon Street, Charlotte, North Carolina 28202. NRC Branch Chief: Bruce A. Watson, CHP.
