SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is issuing a revision 
to an existing 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 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 1 of Regulatory Guide 1.11, Instrument Lines Penetrating 
the Primary Reactor Containment,'' was issued with a temporary 
identification as Draft Regulatory Guide, DG-1225. This guide defines a 
basis that the staff of the NRC considers acceptable to implement the 
intent of General Design Criterion 55 and 56 with regard to instrument 
lines. This guide applies to light-water-cooled reactors with a primary 
containment.

II. Further Information

    In September 2009, DG-1225 was published with a public comment 
period of 60 days from the issuance of the guide. A Summary of the 
Public Comment Resolution is available through the NRC's Agencywide 
Documents Access and Management System (ADAMS) Accession No. 
ML100250972. Electronic copies of Regulatory Guide 1.11, Revision 1 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 Room O-1F21, One White 
Flint North, 11555 Rockville Pike, Rockville, Maryland 20852-2738. 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) 397-4209, 
by fax at (301) 415-3548, and by e-mail to [email protected].
    Regulatory guides are not copyrighted, and NRC approval is not 
required to reproduce them.
