Draft regulatory guide; extension of comment period.
On November 3, 2016, the U.S. Nuclear Regulatory Commission (NRC) issued for public comment draft regulatory guide (DG) DG-1337, “Restart of a Nuclear Power Plant Shut Down by a Seismic Event,” in the Federal Register for a 60-day public comment period which ends on January 3, 2017. The NRC is extending the public comment period to February 28, 2017, recognizing the potential for unavailability of people during the holiday period. The guide describes methods acceptable to the NRC staff that can be used to demonstrate that a nuclear power plant is safe for restarting after a shutdown caused by a seismic event.
Submit comments by February 28, 2017. 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. Although a time limit is given, comments and suggestions in connection with items for inclusion in guides currently being developed or improvements in all published guides are encouraged at any time.

Your request should state that the NRC does not routinely edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment submissions into ADAMS.
II. Additional Information
The NRC is issuing for public comment a DG in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information regarding methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific issues or postulated events, and data that the staff needs in its review of applications for permits and licenses. The DG, entitled “Restart of a Nuclear Power Plant Shut Down by a Seismic Event,” is a proposed revised guide temporarily identified by its task number, DG-1337. The proposed revision of RG 1.167 describes methods acceptable to the NRC staff that can be used to demonstrate that a nuclear power plant is safe for restarting after a shutdown caused by a seismic event. It incorporates lessons learned following the shutdown of nuclear power plants due to earthquake ground shaking and post-earthquake evaluations since Revision 0 was issued in 1997. They include experience gained through the shutdown and restart process of the North Anna nuclear power plant following the Mineral, Virginia earthquake in 2011. It endorses, with some exceptions, sections of ANS/ANSI-2.23-2016, “Nuclear Power Plant Response to an Earthquake,” that relate to post-shutdown inspections and tests, inspection criteria, documentation, and long-term evaluations. The guidance includes an action level matrix to direct actions based on the earthquake level and observed damage levels at a nuclear power plant.
II. Backfitting and Issue Finality
Draft Guide-1337 describes methods acceptable to the NRC staff that can be used to demonstrate that a nuclear power plant is safe for restarting after a shutdown caused by a seismic event. Issuance of this DG, if finalized, would not constitute backfitting as defined in § 50.109 of title 10 of the Code of Federal Regulations (10 CFR) (the Start Printed Page 94434Backfit Rule) and would not otherwise be inconsistent with the issue finality provisions in 10 CFR Part 52. As discussed in the “Implementation” section of this DG, the NRC has no current intention to impose this guide, if finalized, on holders of current operating licenses or combined licenses.
This DG may be applied to applications for operating licenses, combined licenses, early site permits, and certified design rules docketed by the NRC as of the date of issuance of the final regulatory guide, as well as future applications submitted after the issuance of the regulatory guide. Such action would not constitute backfitting as defined in the Backfit Rule or be otherwise inconsistent with the applicable issue finality provision in 10 CFR part 52, inasmuch as such applicants or potential applicants are not within the scope of entities protected by the Backfit Rule or the relevant issue finality provisions in part 52.Start Signature
