The Environmental Protection Agency (EPA) issued three rules on June 19, granting additional powers to states to determine their projected energy resource mixes, including nuclear energy. In response to the rules, utilities should be prepared for possible changes to state policies defining what constitutes “clean” energy and supporting reliability. The rules are intended to go into effect 30 days from their issuance. However, the implementation timeline for the rules is not certain because several states and organizations have stated they intend to challenge the rules in the federal courts.

Staff members from the US Nuclear Regulatory Commission’s (NRC’s) Office of Nuclear Security and Incident Response and Office of Nuclear Reactor Regulation held a public meeting on June 17 to discuss a summary of the Assessment of the NRC’s Power Reactor Cyber Security Program. In response to the Nuclear Energy Institute’s (NEI’s) PRM-73-18, “Petition to Amend 10 CFR 73.54, ‘Protection of Digital Computer and Communication Systems and Networks’,” and based on NRC guidance, this Assessment marked 10 years since the publication of 10 CFR 73.54.
