A fuel bundle assembly for a boiling water nuclear reactor includes an open ended tubular channel subdivided into four quadrants by at least two interior partitions, each quadrant having a sub-fuel bundle assembly having a plurality of fuel rods extending between upper and lower tie plates. An inter-bundle support plate receives a lower end of the channel and has four flow openings at an upper end thereof, such that the lower tie plate of each sub-fuel bundle supported in a respective one of the openings in the support plate. In one embodiment, the sub-fuel bundles within a channel are separated by a cruciform shaped coolant passage. In a second embodiment, the cruciform coolant passage is omitted to thus provide a homogeneous sub-fuel bundle configuration.
A fuel bundle assembly for a boiling water nuclear reactor comprising an open ended tubular channel subdivided into tour quadrants by at least two interior partitions, each quadrant having a sub-fuel bundle assembly enclosed on two adjacent sides of said open ended tubular channel and on two remaining adjacent sides by said interior partition, each sub-fuel bundle assembly comprising at least an 8.times.8 array of fuel rods extending between upper and lower tie plates;
In a reactor core of a boiling water reactor, a plurality of fuel bundle assemblies each comprising an open ended tubular channel subdivided into four quadrants by at least two interior cross ties, each quadrant having a sub-fuel bundle assembly comprising about sixty-four fuel rods extending between upper and lower tie plates, and wherein any group of four of said fuel bundle assemblies arranged in a square array so as to define a cruciform space separating said tour fuel bundle assemblies from each other has a cruciform control rod located within said cruciform space.
