Abstract

Fuel needles in a fast reactor during the heat exchange process are supported and separated by sets of identical plates fixed at regular intervals onto a collar to just fit inside the regular n-sided casing of the system. The plates are both perpendicular to and inclined to the axis of the casing at different stages and the sets join each other and form a rigid structure. Holes in the plates are not the same shape as the needles section. This arrangement mixes the coolant effectively and allows for differential expansion between the needles and the casing.
