ASME Section III Upgrading - Case Studies

Abstract

Nuclear utilities are constantly facing problems obtaining ASME Section III pressureboundary components, due to manufacturers’ not having acceptable American Society of Mechanical Engineers (ASME) III or Technical Standards and Safety Association (TSSA) N285.0 Certificates of Authorization, or allowing their ASME III programs to lapse. The list of qualified manufacturers is relatively tiny, thereby restricting the availability of acceptable pressure-boundary components. Nuclear Logistics, Inc. (NLI) works with cooperative Original Equipment Manufacturer’s (OEM’s) to produce their equipment under NLI’s ASME Section III Certificates of Authorization. This engineering and manufacturing model allows utilities access to a much wider range of pressure-boundary equipment, available from NLI as N285.0 Class 1, 2 or 3. This presentation outlines some case studies describing NLI’s ASME Section III upgrading process.
