SUPPLEMENTARY INFORMATION:

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

[[Page 62894]]

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), entitled, ``Qualification for 
Cement Grouting for Prestressing Tendons in Containment Structures,'' 
is temporarily identified by its task number, DG-1196, which should be 
mentioned in all related correspondence. DG-1196 is proposed Revision 2 
of Regulatory Guide 1.107, dated February 1977.
    This guide describes a method that the staff of the U.S. Nuclear 
Regulatory Commission (NRC) considers acceptable for the use of 
Portland cement grout as the corrosion inhibitor for prestressing 
tendons in prestressed concrete containment structures. This guide also 
provides quality standards for using portland cement grout to protect 
prestressing steel from corrosion.
    The prestressing tendon system of a prestressed concrete 
containment structure is a principal strength element of the structure. 
The ability of the containment structure to withstand the events 
postulated to occur during the life of the structure depends on the 
functional reliability of the structure's principal strength elements. 
Thus, any significant deterioration of the prestressing elements caused 
by corrosion may present a potential risk to public safety. It is 
important that any system for inhibiting the corrosion of prestressing 
elements must possess a high degree of reliability in performing its 
intended function.

II. Further Information

    The NRC staff is soliciting comments on DG-1196. Comments may be 
accompanied by relevant information or supporting data and should 
mention DG-1196 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.

ADDRESSES: You may submit comments by any one of the following methods. 
Please include Docket ID NRC-2010-0321 in the subject line of your 
comments. Comments submitted in writing or in electronic form will be 
posted on the NRC Web site and on the Federal rulemaking Web site 
Regulations.gov. 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.
