I. Introduction

The U.S. Nuclear Regulatory Commission (NRC) has issued for public comment a draft regulatory 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), titled, “General Design Guide for Ventilation Systems of Plutonium Processing and Fuel Fabrication Plants,” is temporarily identified by its task number, DG-3034, which should be mentioned in all related correspondence.

Proposed Revision 1 of Regulatory Guide 3.12 describes a method that the staff of the NRC considers acceptable for use in complying with 10 CFR 70.23(a)(3) and (a)(4) with respect to the design of ventilation systems for plutonium processing and fuel fabrication plants. At plutonium processing and fuel fabrication plants, a principal risk to health and safety is the release and dispersal of radioactive materials. The prevention of such release and dispersal is an important function of the ventilation systems. To meet these objectives, this guide provides recommendations for achieving defense in depth and for Start Printed Page 44780minimizing the release of radioactive materials to the environment.

Each applicant for a license to possess and use special nuclear material in a plutonium processing and fuel fabrication plant as defined in 10 CFR 70.4, “Special Nuclear Material,” must satisfy the provisions of 10 CFR 70.23, “Requirements for the approval of applications.” Paragraphs (a)(3) and (a)(4) of 10 CFR 70.23 require that the applicant's proposed equipment, facility, and procedures be adequate to protect health and minimize danger to life or property.

II. Further Information

The NRC staff is soliciting comments on DG-3034. Comments may be accompanied by relevant information or supporting data, and should mention DG-3034 in the subject line.

Comments would be most helpful if received by October 1, 2008. 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.
