Description:  On 8 September 2023, the U.S. Nuclear Regulatory Commission (NRC) requested 
comments on the regulatory basis to support a rulemaking to amend the NRC's regulations related 
to the use of conventional and accident tolerant light -water reactor fuel designs. The public comment 
period was originally scheduled to close on 22 November 2023. The NRC has decided to extend the 
public comment period to allow more time for members of the public to develop and submit their 
comments.  
The due date of comments requested in the document published on 8 September 2023 ( 88 FR 
61986 ) is extended. Comments should be fil ed no later than 22 January 2024. Comments received 
after this date will be considered, if it is practical to do so, but the NRC is able to ensure consideration 
only for comments received on or before this date.
