Bulletin 2004-01 Inspection of Alloy 82/182/600 Materials Used in 
the Fabrication of Pressurizer Penetrations and Steam Space Piping 
Connections at Pressurized-Water Reactors (PWRs); Notice of 

AGENCY: U.S. Nuclear Regulatory Commission.

ACTION: Notice of issuance.


SUMMARY: The Nuclear Regulatory Commission (NRC) has issued NRC 
Bulletin 2004-01 to all holders of operating licenses for PWRs except 
those who have permanently ceased operations and have certified that 
fuel has been permanently removed from the reactor pressure vessel. The 
NRC is issuing this bulletin to:
    (1) Advise PWR licensees that current methods of inspecting Alloy 
82/182/600 materials used in the fabrication of pressurizer 
penetrations and steam space piping connections may need to be 
supplemented with additional measures to detect and adequately 
characterize flaws due to primary water stress corrosion cracking,
    (2) Request PWR addressees to provide the NRC with information 
related to the materials from which the pressurizer penetrations and 
steam space piping connections at their facilities were fabricated,
    (3) Request PWR licensees to provide the NRC with information 
related to the inspections that have been and those that will be 
performed to ensure that degradation of Alloy 82/182/600 materials used 
in the fabrication of pressurizer penetrations and steam space piping 
connections will be identified, adequately characterized, and repaired, 
    (4) Require PWR addresses to provide a written response to the NRC 
in accordance with the provisions of Section 50.54(f) of Title 10 of 
the Code of Federal Regulations (10 CFR 50.54(f)).

DATES: The bulletin was issued on May 28, 2004.
