The system is based on natural convection cooling with outlet temperature 550°C. It could be somewhat higher ~800°C subject to improved materials development. It can be used within a long life closed fuel cycle of up to 30 years in some concepts. It is anticipated to be used for electricity production, hydrogen production and actinide management.
