Regulatory guide; issuance.


The U.S. Nuclear Regulatory Commission (NRC) is issuing a revision to Regulatory Guide (RG) 4.11, “Terrestrial Environmental Studies for Nuclear Power Stations.” This guide provides technical guidance that the NRC staff considers acceptable for terrestrial environmental studies and analyses supporting licensing decisions for nuclear power reactors.

I. Introduction

The NRC is issuing a revision to an existing guide in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information such as methods that are acceptable to the NRC staff for implementing specific parts of the agency'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.

Revision 2 of RG 4.11 was issued with a temporary identification as Draft Regulatory Guide, DG-4016. This guide focuses on terrestrial analyses for licensing new nuclear power stations under Title 10 of the Code of Federal Regulations (10 CFR) part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” and power reactors under 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities” and this guide is also useful in identifying the more limited studies and analyses needed for nuclear reactor operating license renewal under 10 CFR part 54, “Requirements for Renewal of Operating Licenses for Nuclear Power Plants,” and portions may also be relevant to nuclear reactor decommissioning.

II. Further Information

DG-4016, was published in the Federal Register on August 12, 2011 (76 FR 50274) for a 60-day public comment period. The public comment period closed on October 14, 2011. No public comments were received.
