Absorber tube for BWR control rods

摘要

In a control rod having a plurality of elongated members for absorbing neutrons within a nuclear reactor to control a nuclear reaction, each elongated member may include a cylindrical inner capsule configured to contain neutron absorbing material therein. The elongated member may also include an absorber tube enclosing the cylindrical inner capsule, the absorber tube having an outer surface configured with a plurality of generally flat, planar sides between adjacent rounded corners.

1. In a control rod having a plurality of elongated members for absorbing neutrons within a nuclear reactor to control a nuclear reaction, each elongated member comprising:
a cylindrical inner capsule configured to contain neutron absorbing material therein; and an absorber tube enclosing the cylindrical inner capsule, the absorber tube having an outer surface with two opposing generally flat, planar, mating sides each of which is configured to mate flushly with a planar mating side of an adjacent absorber tube without the existence of a gap between the mated absorber tubes, the opposing flat, planar, mating sides each being located directly in between respective adjacent rounded corners that are convex in relation to the center of the capsule, wherein a line bisecting each of the flat, planar, mating sides is substantially collinear with a central axis of the control rod.
