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 Start Printed Page 40630staff needs in its review of applications for permits and licenses.

The draft regulatory guide (DG), entitled, “Initial Startup Test Program to Demonstrate Remote Shutdown Capability for Water-Cooled Nuclear Power Plants,” is temporarily identified by its task number, DG-1236, which should be mentioned in all related correspondence. DG-1236 is proposed Revision 2 of Regulatory Guide 1.68.2, dated July 1978.

This guide describes an initial startup test program acceptable to the NRC staff for demonstrating hot shutdown capability and the potential for cold shutdown from outside the control room. This guide is applicable to water-cooled nuclear power plants.

Title 10, Part 50, of the Code of Federal Regulations (10 CFR Part 50), “Domestic Licensing of Production and Utilization Facilities,” and 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants,” 10 CFR 50.34, “Contents of Applications; Technical Information,” and 10 CFR 52.79, “Contents of Application, Technical Information in FSAR,” require, in part, that an applicant for a license to operate a production or utilization facility provide a safety analysis report (SAR) that includes the principal design criteria for the proposed facility. The introduction to Appendix A, “General Design Criteria for Nuclear Power Plants,” to 10 CFR Part 50 states that these principal design criteria are to establish the necessary design, fabrication, construction, testing, and performance requirements for structures, systems, and components (SSCs) important to safety (i.e., SSCs that provide reasonable assurance that the facility can be operated without undue risk to the health and safety of the public).

II. Further Information

The NRC staff is soliciting comments on DG-1236. Comments may be accompanied by relevant information or supporting data and should mention DG-1236 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).

Because your comments will not be edited to remove any identifying or contact information, the NRC cautions you against including any information in your submission that you do not want to be publicly disclosed.

The NRC requests that any party soliciting or aggregating comments received from other persons for submission to the NRC inform those persons that the NRC will not edit their comments to remove any identifying or contact information, and therefore, they should not include any information in their comments that they do not want publicly disclosed. You may submit comments by any of the following methods:

1. Mail comments to: Rulemaking and Directives Branch, Mail Stop: TWB-05-B01M, Division of Administrative Services, Office of Administration, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001.

3. Fax comments to: Rulemaking and Directives Branch, Office of Administration, U.S. Nuclear Regulatory Commission at (301) 492-3446.

Requests for technical information about DG-1236 may be directed to the NRC contact, Jonathan Ortega-Luciano at (301) 251-7627 or e-mail to

Comments would be most helpful if received by October 9, 2009. 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.
