Abstract

This disclosure describes, in part, systems and structures for an exhaust assembly that includes an exhaust tube and a coolant passage. The exhaust tube is oriented about an axis and an exhaust gas is configured to flow through the exhaust tube in a direction away from an end of the exhaust tube. The coolant passage is oriented about the axis radially outward of the exhaust tube, the coolant passage having an inner shell and an outer shell. The heat capacity of the volume of the coolant contained within the coolant passage is above a threshold ratio of a heat capacitance of a radiation shield, exhaust tube, and inner shell of the coolant passage to prevent coolant boiling after shutdown.
