There is an ongoing effort within the ASME Boiler and Pressure Vessel Committee on Construction of Nuclear Facility Components (Section III) to develop rules for the construction of fusion energy devices. The Standards Committee of Section III, Division 4 and its Subgroup on Fusion Energy Devices are developing these new fusion Code rules. These rules cover fusion-energy-related components such as vacuum vessels, cryostats, and magnet structures and the interactions of these components. Related support structures, including metallic and nonmetallic materials; containment or confinement structures; and in-vessel components such as blankets, divertors, shield fusion-system piping, vessels, valves, pumps, and supports, are also covered. The rules include requirements for materials, design, fabrication, testing, examination, inspection, certification, and stamping.

The following proposed Subparts and Subsections are in development and might be included in future editions:

• Subpart FBA: Magnets
• Subpart FBC: Target Chamber
• Subsection FC: In-Vessel Components
• Subsection FD: Material
• Subsection FE: Support Structures
• Subsection FF: Balance of Plant Equipment

Careful application of this Section will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.
