SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is withdrawing without 
replacement Regulatory Guide (RG) 1.150, ``Ultrasonic Testing of 
Reactor Vessel Welds During Preservice and Inservice Examinations,'' 
which was published in February 1983, because it has been superseded by 
Title 10 of the Code of Federal Regulations (10 CFR) section 
50.55a(g)(6)(ii)(C)(1), ``Inservice inspection requirements,'' 
incorporation by reference of an American Society of Mechanical 
Engineers (ASME) standard.
    Specifically, 10 CFR 50.55a(g)(6)(ii)(C)(1) requires both 
preservice and inservice inspection activities to be performed using 
personnel, equipment, and procedures qualified in accordance with the 
ASME, Boiler and Pressure Vessel Code, section XI, Appendix VIII.

II. Further Information

    The withdrawal of RG 1.150 does not, in and of itself, alter any 
prior or existing licensing commitments based on its use. The current 
version of RG 1.150 represents a method that is no longer acceptable to 
the staff. RGs may be withdrawn when their guidance is superseded by 
congressional action, the methods or techniques described in the RG no 
longer describe an acceptable approach, or the RG does not provide 
useful information.
    RGs are available for inspection or downloading through the NRC's 
public Web site in the ``Regulatory Guides'' collection of the NRC's 
Electronic Reading Room at http://www.nrc.gov/reading-rm/doc-
collections. RGs are also available for inspection at the NRC's Public 
Document Room (PDR), Room O-1F21, One White Flint North, 11555 
Rockville Pike, Rockville, Maryland 20852-2738. The PDR's mailing 
address is U.S. NRC PDR, Washington, DC 20555-0001. The PDR staff can 
be reached by telephone at 301-415-4737 or 800-397-4209, by fax at 301-
415-3548, and by e-mail to pdr@nrc.gov.
    RGs are not copyrighted and NRC approval is not required to 
reproduce them.

    Dated at Rockville, Maryland, this 4th day of February, 2008.

    For the Nuclear Regulatory Commission.

Andrea D.Valentin,
Chief, Regulatory Guide Development Branch, Division of Engineering, 
Office of Nuclear Regulatory Research.
