Notice of Issuance and Availability of Draft Regulatory Guide, DG-1247, “Design-Basis Hurricane and Hurricane Missiles for Nuclear Power Plants.”

                        Robert G. Carpenter, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001,                         *telephone:*                         (301) 251-7483 or e-mail                         *Robert.Carpenter@nrc.gov.*

# SUPPLEMENTARY INFORMATION:

## I. Introduction

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft guide in the agency's “Regulatory Guide” series. This series was developed to describe and make available to the public such information as 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 problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.

The draft regulatory guide (DG), entitled, “Design-Basis Hurricane and Hurricane Missiles for Nuclear Power Plants,” is temporarily identified by its task number, DG-1247, which should be mentioned in all related correspondence. DG-1247 is a proposed new regulatory guide.

This regulatory guide provides licensees and applicants with new guidance that the staff of the NRC considers acceptable for use in selecting the design-basis hurricane and design-basis hurricane-generated missiles that a nuclear power plant should be designed to withstand to prevent undue risk to the health and safety of the public. This guidance applies to the contiguous United States but does not address the determination of the design-basis hurricane and hurricane missiles for sites located along the Pacific coast or in Alaska, Hawaii, or Puerto Rico; the NRC will evaluate such determinations on a case-by-case basis. This guide also does not identify the specific structures, systems, and components that should be designed to withstand the effects of the design-basis hurricane or should be protected from hurricane-generated missiles and remain functional. Nor does this guide address other externally generated hazards, such as aviation crashes, nearby accidental explosions resulting in blast overpressure levels and explosion-borne debris and missiles, and turbine missiles.

## II. Further Information

The NRC staff is soliciting comments on DG-1247. Comments may be accompanied by relevant information or supporting data and should mention DG-1247 in the subject line. Comments submitted in writing or in electronic form will be made available to the public in their entirety through the NRC's Agencywide Documents Access and Management System (ADAMS).

Comments would be most helpful if received by October 21, 2010. Comments received after that 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.

# ADDRESSES:
