The rules of Subsection FA, Subpart FAA constitute the general requirements associated with fusion components used in the construction of fusion devices and their supporting systems. Only those fusion components that are serving a pressure boundary and/or structural integrity function (see FAA-2120) are covered by these rules.

Items that are specifically excluded are electrical components and superconducting strand. It is understood that these rules were developed to document rules for construction that are not adequately addressed within existing Divisions of Section III of the ASME Boiler and Pressure Vessel Code (BPVC) or other existing codes and standards used in the nuclear industry.
