Creators

Description

A mini-bundle of fuel rods is described for use in each of several separate compartments of a BWR fuel assembly, the compartments being formed by an outer hollow tubular flow channel for directing the flow of coolant/moderator fluid through the fuel assembly and a hollow water cross extending through the channel, attached so as to provide a central hollow channel for flow of coolant/moderator fluid through the fuel assembly and to divide the outer channel into the separate compartments. The bundle consists of an interior array of fuel rods, each being of a predetermined diameter size; and a peripheral array of fuel rods, each being of a second diameter greater than the first diameter size
