I. Background

In a September 4, 2015, Federal Register document (80 FR 53478), the NRC solicited comment from members of the public on a draft regulatory basis addressing the need for a rulemaking to implement cyber security for FCFs. The public comment period ended on October 5, 2015. The NRC received a total of 9 comment submissions from nongovernment organizations and industry. The NRC staff reviewed and considered the comments in finalizing the regulatory basis. The final regulatory basis is available in ADAMS under Accession No. ML15355A466 or on the Federal rulemaking Web site,, under Docket ID NRC-2015-0179.

II. Publicly-Available Documents

As the NRC continues its ongoing proposed rulemaking effort to implement cyber security requirements for FCFs in part 73 of title 10 of the Code of Federal Regulations, the NRC is making documents publicly available on the Federal rulemaking Web site,, under Docket ID NRC-2015-0179. By making these documents publicly available, the NRC seeks to inform stakeholders of the current status of the NRC's rulemaking development activities and to provide preparatory material for future public meetings.

The NRC may post additional materials relevant to this rulemaking at, under Docket ID NRC-2015-0179. Please take the following actions if you wish to receive alerts when changes or additions occur in a docket folder: (1) Navigate to the docket folder (NRC-2015-0179); (2) click the “Email Alert” link; and (3) enter your email address and select how frequently you would like to receive emails (daily, weekly, or monthly).

Although regulations are exempt under the Act, the NRC is applying the same principles to its rulemaking documents. Therefore, the NRC has written this document to be consistent with the Plain Writing Act.
