I. Introduction

    The NRC is issuing Regulatory Guide (RG) 1.193 in the agency's 
``Regulatory Guide'' series. This series was developed to describe and 
make available to the public specific program information. This 
information includes methods acceptable to the NRC staff for 
implementing specific parts of the agency's regulations, techniques the 
staff uses in evaluating specific problems or postulated accidents, and 
data the staff needs in its review of applications for permits and 

II. Discussion

    RG 1.193 lists the Code Cases that NRC has determined not to be 
acceptable for use on a generic basis. Two separate RGs list Code Cases 
that NRC has found to be acceptable alternatives to requirements in the 
American Society of Mechanical Engineers (ASME) Boiler and Pressure 
Vessel Code. RG 1.84, Rev. 35, ``Design, Fabrication, and Materials 
Code Case Acceptability, ASME Section III,'' lists all Section III Code 
Cases that NRC has approved for use. RG 1.147, Rev. 16, ``Inservice 
Inspection Code Case Acceptability, ASME Section XI, Division 1,'' 
lists all Section XI Code Cases that NRC has approved for use. RG 1.84 
and RG 1.147 are being noticed under a separate notice of availability.
    For Revision 3 of RG 1.193, NRC reviewed the Code Cases listed in 
Supplements 2-11 to the 2004 Edition of the ASME Boiler and Pressure 
Vessel (BPV) Code and Supplement 0 to the 2007 Edition (Supplement 0 
also serves as Supplement 12 to the 2004 Edition). A brief description 
of the basis for the unacceptability determination is provided with 
each Code Case in RG 1.193. Licensees may submit a request to implement 
one or more of the Code Cases listed in RG 1.193 through 10 CFR 
50.55a(a)(3), which permits the use of alternatives to the Code 
requirements referenced in 10 CFR 50.55a provided that the proposed 
alternatives result in an acceptable level of quality and safety. 
Licensees must submit a plant-specific request that addresses NRC's 
concerns about the Code Case at issue.

III. Further Information

    In June 2009, draft Regulatory Guide (DG) 1191, DG 1192, and DG 
1193 were published with a public comment period of 60 days from their 
issuance. The comment period closed on August 16, 2009. Copies of the 
final RGs are available in ADAMS under Accession Numbers ML101800532 
(RG 1.84), ML101800536 (RG 1.147), and ML101800540 (RG 1.193).
    The responses to the public comments on the three RGs are contained 
in the final rule that incorporates RG 1.84 and RG 1.147 by reference 
into Title 10, part 50, of the Code of Federal Regulations (10 CFR part 
50), ``Domestic Licensing of Production and Utilization Facilities,'' 
and is available in NRC's Agencywide Documents Access and Management 
System (ADAMS) under Accession No. ML100560148. For further information
