IMPROVEMENTS IN THE HEAT EXCHANGE OF FINNED FUEL ELEMENTS IN A NUCLEAR REACTOR

Patent ·
OSTI ID:4101660
In order to improve the heat transfer between the longitudinal or helicoidal finned fuel elements and the coolant, graphite rings are arranged around the fins at intervals along the coolant channel. These rings may have a nozzle form or some other convergent shape of the profile. They create turbulences around their profiles. In another embodiment the pitch of the helicoidal fins is sufficiently low that the transverse effect of the fins is predominant. In a last embodiment the fins have notches forming in their turn helicoidal channels. (NPO)
