Nuclear Regulatory Commission June 19, 2020 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) has recently submitted a renewal of an existing collection of information to the Office of Management and Budget (OMB) for review. The information collection is entitled, ``Requests to Agreement States for Information.''

The U.S. Nuclear Regulatory Commission (NRC) is issuing regulatory guide (RG) 1.236, ``Pressurized-Water Reactor Control Rod Ejection and Boiling-Water Reactor Control Rod Drop Accidents.'' This is a new RG that provides guidance for analyzing control rod accidents. It defines fuel cladding failure thresholds for ductile failure, brittle failure, and pellet-clad mechanical interaction. It also describes analytical limits and guidance for demonstrating compliance with regulations governing reactivity limits. RG 1.236 supersedes the guidance for control rod ejection accidents in RG 1.77, ``Assumptions Used for Evaluation a Control Rod Ejection Accident for Pressurized Water Reactors,'' which is being withdrawn in conjunction with the issuance of RG 1.236.

On April 2, 2020, the U.S. Nuclear Regulatory Commission (NRC) received the post-shutdown decommissioning activities report (PSDAR) for the Duane Arnold Energy Center (DAEC). The PSDAR, which includes the site-specific decommissioning cost estimate (DCE), provides an overview of NextEra Energy Duane Arnold, LLC's (NEDA or the licensee) planned decommissioning activities, schedule, projected costs, and environmental impacts for DAEC. The NRC will hold a public meeting to discuss the PSDAR's content and receive comments.
