Abstract
A neutron absorbing insert for use in a fuel rack. In one aspect, the insert includes: a plate structure having a first wall and a second wall that is non-coplanar to the first wall; the first and second walls being formed by a single panel of a metal matrix composite having neutron absorbing particulate reinforcement that is bent into the non-coplanar arrangement along a crease; and a plurality of spaced-apart holes formed into the single panel along the crease prior to bending.
Claims11
A neutron absorbing apparatus comprising:
- a boron-containing sleeve configured for insertion into a cell of a nuclear fuel rack configured for holding a nuclear fuel assembly, the sleeve comprising a plate structure including a first longitudinal wall and a second longitudinal wall that is non-coplanar to the first wall;
- the first and second longitudinal walls each having a top end;
- and
- a reinforcement assembly coupled to the top ends of the first and second longitudinal walls;
- wherein the reinforcement assembly is configured to add structural rigidity to the sleeve such that the sleeve may be lifted by the reinforcement assembly;
- wherein the sleeve has a chevron shape;
- wherein the top end of the first and second longitudinal walls each comprise a bent flange, the reinforcement assembly being coupled to the bent flanges;
- and
- wherein the flanges are inwardly bent and oriented 90 degrees to the first and second longitudinal walls of the sleeve.
