Abstract
This disclosure describes various configurations and components for bimetallic and trimetallic claddings for use as a wall element separating nuclear material from an external environment. The cladding materials are suitable for use as cladding for nuclear fuel elements, particularly for fuel elements that will be exposed to sodium or other coolants or environments with a propensity to react with the nuclear fuel.
Claims18
A steel-middle layer-vanadium cladding manufacturing method comprising:
- fabricating a steel tube;
- fabricating a vanadium tube of carbon-doped vanadium or vanadium alloy;
- depositing one of nickel, nickel alloy, chromium, chromium alloy, zirconium or zirconium alloy one either the inside of the steel tube or the outside of the vanadium tube;
- inserting the vanadium tube into the steel tube thereby creating a steel-middle layer-vanadium intermediate tube;
- metallurgical bonding the steel-middle layer-vanadium intermediate tube;
- pilgering or extruding the steel-middle layer-vanadium intermediate tube;
- and
- cold working the steel-middle layer-vanadium intermediate tube after the metallurgical bonding and pilgering or extruding operations to obtain a steel-middle layer-vanadium cladding.
