Abstract
An absorber body arranged to absorb radiation in a nuclear energy arrangement. The absorber body comprises more than one area with a locally reduced thickness.
Claims16
An absorber body operable to absorb radiation in a nuclear reactor, comprising:
- an elongated rod of neutron absorbing material operable to be positioned in a channel in a control rod to control neutron flux in a nuclear reactor, the elongated rod comprising two ends and at least two areas with a locally reduced thickness, wherein a first of the areas with a locally reduced thickness is arranged at a first of the two ends of the elongated rod and a second of the areas with a locally reduced thickness is arranged at a second of the two ends of the elongated rod, wherein the areas with a locally reduced thickness, in addition to the first and second areas, comprise at least one recess arranged in an outer surface of the elongated rod between the first and second areas.
A device operable to control neutron flux in a nuclear reactor, comprising:
- a control rod comprising four blades that extend from a center of the control rod, each blade comprising a free outer end and a plurality of channels that extend from the free outer end toward the center of the control rod;
- and
- an absorber body arranged in at least some of the channels, the absorber body comprising an elongated rod of neutron absorbing material operable to control the neutron flux in the nuclear reactor, the elongated rod comprising two ends and at least two areas with a locally reduced thickness, wherein a first of the areas with a locally reduced thickness is arranged at a first of the two ends and a second of the areas with a locally reduced thickness is arranged at a second of the two ends of the absorber body.
