The U.S. Nuclear Regulatory Commission (NRC) has released a draft regulatory guide, DG-1303, for public comment, titled "Application and Testing of Safety-Related Diesel Generators in Nuclear Power." This guide, a revision of Regularity Guide 1.9, provides updated guidance for ensuring emergency power supplies in nuclear power plants meet safety regulations. The draft endorses certain IEEE standards to certify that these power supplies are reliable and capable during emergencies. The public can submit comments by February 18, 2021, through various channels detailed in the notice.
