The U.S. Nuclear Regulatory Commission (NRC) is releasing Revision 4 to their Regulatory Guide 1.136, titled “Design Limits, Loading Combinations, Materials, Construction, and Testing of Concrete Containments.” This guide updates the standards and guidance for materials and procedures used in building concrete containment structures in nuclear power plants. It endorses, with specific exceptions, the 2019 version of codes set by the American Society of Mechanical Engineers (ASME) related to such constructions. The document also clarifies that the new guide isn't mandatory for license holders, meaning they aren't required to follow it, though it provides useful methodologies to meet existing regulatory requirements.

The U.S. Nuclear Regulatory Commission (NRC) has announced a request for public comments on the renewal of an existing information collection titled "Domestic Licensing of Production and Utilization Facilities." This request is in accordance with the Paperwork Reduction Act of 1995, and the NRC is seeking comments by April 20, 2021. The information collected is essential for the NRC to evaluate applications and amendments related to nuclear power plants and other facilities to ensure public health and safety. The NRC encourages electronic submission of comments and provides detailed information on how to access documents and submit feedback.

The U.S. Nuclear Regulatory Commission (NRC) has released a draft report, NUREG-1482, Revision 4, for public comment. This document provides guidance on testing programs for pumps, valves, and dynamic restraints, known as snubbers, in nuclear power plants. It emphasizes the NRC's role in developing standards alongside the American Society of Mechanical Engineers (ASME). Comments can be submitted electronically by April 14, 2025, and the report reflects updates to reflect lessons learned and operational experiences.

The Nuclear Regulatory Commission (NRC) is reopening the public comment period for a draft regulatory guide, DG-1361, titled "Environmental Qualification of Certain Electrical Equipment Important to Safety for Nuclear Power Plants." Originally published for comments on December 17, 2020, the initial comment period ended on February 16, 2021. To provide more time for feedback, the NRC has extended the comment period by an additional 60 days, with a new deadline of April 19, 2021. The draft guide proposes a new standard for assessing the safety equipment at nuclear power plants and includes updates from past standards and additional international guidelines.

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.

The U.S. Nuclear Regulatory Commission (NRC) has issued Revision 1 to its Regulatory Guide 1.191, titled "Fire Protection Program for Nuclear Power Plants During Decommissioning." This updated guide provides new information that has emerged since the original version and includes guidance for plants that have adhered to the National Fire Protection Association's Standard 805 for fire protection. The guide specifies methods the NRC considers acceptable for fire protection in plants that have stopped operating and removed fuel from reactor vessels. Despite issuing this guide, the NRC does not currently plan to enforce its recommendations in a way that changes existing regulations or requirements.
