# AGENCY:

Nuclear Regulatory Commission.

# ACTION:

Proposed rule; extension of comment period.

# SUMMARY:

On July 1, 2021, the U.S. Nuclear Regulatory Commission (NRC) issued for public comment proposed amendments to its regulations to certify the NuScale standard design for a small modular reactor. The public comment period was originally scheduled to close on August 30, 2021. The NRC has decided to extend the public comment period by an additional 45 days to allow more time for members of the public to develop and submit their comments.

# DATES:

The comment period for the document published on July 1, 2021 (86 FR 34999) is extended. Comments should be filed no later than October 14, 2021. Comments received after this date will be considered, if it is practical to do so, but the Commission is able to ensure consideration only for comments received on or before this date.

# ADDRESSES:

You may submit comments by any of the following methods (unless the document published on July 1, 2021, describes a different method for submitting comments on a specific subject); however, the NRC encourages electronic comment submission through the Federal rulemaking website:

## I. Discussion

On July 1, 2021, the NRC solicited comments on the proposed NuScale small modular reactor design certification. The NRC proposed amendments to its regulations so that applicants or licensees intending to construct and operate a NuScale standard design may do so by referencing the design certification rule. The public comment period was originally scheduled to close on August 30, 2021.

On July 27, 2021, the NRC received a public comment (ADAMS Accession No. ML21209A763) requesting that the comment period for the proposed rule be extended by an additional 90 days. The request states that due to the large volume of related documents that need to be reviewed, additional time is needed to submit comments. No specific basis was given for requesting an additional 90 days to prepare comments.

The NRC seeks to ensure that the public has a reasonable opportunity to provide the NRC with comments on this proposed action. The NRC acknowledges that the rulemaking documents contain a significant amount of information. However, the NRC is also responsible for deciding whether to issue a design certification within a reasonable time. Accordingly, to balance these interests, the NRC has decided to extend the comment period for the proposed rule for an additional 45 days. A 45-day extension provides a reasonable opportunity for all stakeholders to review these documents and to develop informed comments on these documents, while not unduly delaying the NRC's final decision on the design certification.

The NRC has decided to extend the public comment period for the proposed rule until October 14, 2021, to allow more time for members of the public to submit their comments.

Dated: August 17, 2021.

For the Nuclear Regulatory Commission.

Annette L. Vietti-Cook,

Secretary of the Commission.
