SUPPLEMENTARY INFORMATION: 

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC or Commission) is 
issuing a new guide in the agency'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

[[Page 48382]]

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.
    Regulatory Guide 1.216, ``Containment Structural Integrity 
Evaluation for Internal Pressure Loadings Above Design-Basis 
Pressure,'' was issued with a temporary identification as Draft 
Regulatory Guide, DG-1203. This guide describes methods that the NRC 
staff considers acceptable for (1) predicting the internal pressure 
capacity for containment structures above the design-basis accident 
pressure, (2) demonstrating containment structural integrity related to 
combustible gas control, and (3) demonstrating containment structural 
integrity to meet the Commission's performance goals related to the 
prevention and mitigation of severe accidents. It provides guidance on 
methods for satisfying requirements in Title 10 of the Code of Federal 
Regulations (10 CFR) Part 52, ``Licenses, Certifications, and Approvals 
for Nuclear Power Plants.'' Requirements in 10 CFR 52.47, ``Contents of 
Applications; Technical Information,'' and in 10 CFR 52.79, ``Contents 
of Applications; Technical Information in Final Safety Analysis Report 
[FSAR],'' relate to the structural integrity of containments under 
internal pressurization that pertain to the containment structural 
capacity above design-basis pressures, to combustible gas control, and 
to the prevention and mitigation of severe accidents. This guidance is 
intended to be consistent with the Commission's goals and other related 
guidance, as discussed in the remainder of this section. This 
regulatory guide does not address requirements and guidance for the 
structural evaluation of containments for design-basis pressure.

II. Further Information

    In December 2008, DG-1203 was published with a public comment 
period of 60 days from the issuance of the guide. The public comment 
period closed on February 9, 2009. The staff's responses to the public 
comments received are located in the NRC's Agencywide Documents Access 
and Management System under Accession Number ML092800554. The 
regulatory analysis may be found in ADAMS under Accession No. 
ML101890047. Electronic copies of RG 1.216 are available through the 
NRC's public Web site under ``Regulatory Guides'' at http://www.nrc.gov/reading-rm/doc-collections/.
    In addition, regulatory guides are available for inspection at the 
NRC's Public Document Room (PDR) located at 11555 Rockville Pike, 
Rockville, Maryland. The PDR's mailing address is USNRC PDR, 
Washington, DC 20555-0001. The PDR can also be reached by telephone at 
(301) 415-4737 or (800) 397-4205, by fax at (301) 415-3548, and by e-
mail to [email protected].
    Regulatory guides are not copyrighted, and Commission approval is 
not required to reproduce them.

    Dated at Rockville, Maryland, this 3rd day of August, 2010.
