Abstract
Channel boxes for a boiling water reactor and methods of manufacture thereof are provided. The channel box comprises a substrate and a first layer. The substrate comprises a tubular shape. The substrate comprises silicon carbide fibers. The first layer is deposited on a first surface of the substrate and the first layer comprises a corrosion resistant metallic composition.
Claims20
A channel box for a boiling water reactor, the channel box comprising:
- a substrate comprising a tubular shape, the substrate comprising silicon carbide fibers;
- and
- a first layer deposited on a first surface of the substrate, wherein the first layer comprises a corrosion resistant metallic composition.
A pre-irradiated channel box for a boiling water reactor, the channel box comprising:
- a substrate comprising a tubular shape, the substrate comprising silicon carbide fibers;
- and
- a first layer deposited on a surface of the substrate, wherein the first layer comprises a corrosion resistant metallic composition,
- wherein each side of the channel box has been exposed to radiation until a fluence of at least 1 displacement per atom was achieved.
A method for making a channel box for a boiling water reactor, the method comprising:
- layering silicon carbide fibers around a form to create a preform of silicon carbide fibers;
- depositing an interlayer on the silicon carbide fibers;
- creating the substrate from the preform, wherein the substrate comprises a tubular shape;
- removing the substrate from the form;
- and
- depositing a first layer on a first surface of the substrate thereby forming the channel box, wherein the first layer comprises a corrosion resistant metallic composition.
