The U.S. Nuclear Regulatory Commission (NRC) is correcting a final rule that appeared in the Federal Register on November 29, 2019, and was corrected on December 5, 2019. The document amended the NRC's regulations to reflect internal organizational changes and make conforming amendments, including removing all references to the Office of New Reactors because that office has merged with the Office of Nuclear Reactor Regulation, changing the names of divisions that are affected by the reorganization of the Office of Nuclear Material Safety and Safeguards, and making conforming amendments throughout the regulations to reflect the office merger and the office reorganization.
