During the 501st meeting of the Advisory Committee on Reactor Safeguards, April 10-12, 2003, the Committee considered the draft final amendment to 10 CFR 50.55a to incorporate by reference the following Regulatory Guides that list code cases published by the American Society of Mechanical Engineers (ASME) and approved by the NRC staff:

• Regulatory Guide 1.84, Revision 32 (DG-1090), "Design, Fabrication, and Materials Code Case Acceptability, ASME Section III"
• Regulatory Guide 1.147, Revision 13 (DG-1091), "Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1"
• Regulatory Guide 1.192 (DG-1089), "Operation and Maintenance Code Case Acceptability, ASME OM Code"

In addition, the Committee considered Regulatory Guide 1.193 (DG-1112), "ASME Code Cases Not Approved for Use," which is not referenced in the draft final amendment to 10 CFR 50.55a.
