Blackburn, G; Morgan, V

A valved coaxial duct for fluid flow between a heat exchanger and a heat source, e.g., a nuclear reactor, is designed with the inner pipe passing hot fluid into the exchanger and the annulus between the pipes leading cool fluid out. Butterfly valves are disposed in both hot and cool fluid flows. The inner pipe is insulated from the outer pipe to minimize heat loss. The coaxial design simplifies thermal expansion and contraction problems, and the position of the valves minimizes their possible distortion by thermal changes. (D.L.C.)
