Abstract
A grid structure for the support of elongate objects, such as boxes containing the fuel elements of a nuclear reactor, comprises several parallel metal plates with machined, aligned apertures receiving the boxes, the plates being interconnected by transverse stays secured thereto preferably by welding. In the case of square or otherwise rectangular apertures, the residual plate material forms an orthogonal array of narrow strips whose intersections are the anchor points for the stays.
Claims5
In a nuclear reactor, in combination:
- a plurality of substantially nondeformable parallel metal plates each forming an integral orthogonal array of strips defining between them a multiplicity of apertures whose dimensions substantially exceed the width of said strips, the apertures of all said plates being aligned with one another to seat a bank of elongate fuel-element containers transverse to said plates;
- and
- a set of rigid stays transverse to said plates aligned with said strips and secured thereto for holding said plates at a fixed distance from one another.
