This standard provides nuclear safety criteria for the control air system that furnishes compressed air to safety-related components in nuclear power plants. It applies only to the air supply system and does not apply to air-operated devices. This standard provides: (1) the system nuclear safety design requirements for equipment, piping, instruments, and controls that constitute the control air supply system, and (2) the nuclear safety design requirements to accommodate testing and maintenance necessary to ensure adequate nuclear safety performance of the control air system.
