IMPROVEMENTS IN OR RELATING TO PROTECTIVE CANS FOR NUCLEAR REACTOR FUEL ELEMENTS

Patent ·
OSTI ID:4095234
A finned tube design for reactor fuel elements is described in which the fins are slotted and longitudinal, and baffles are interposed between adjacent fins. Each baffle is arranged so that its distance from the tube body varies from a maximum at one end (fin tips) to a minimum at the other end (fin roots). The advantages of this design are that the heat transfer performance of the tube is improved, radial coolant temperature gradients are reduced by the baffles, and the longitudinal fins strengthen the tube better than transverse fins.
