Abstract
An assembly for nuclear applications includes a tubular cladding for containing nuclear fuel. The tubular cladding comprises a ceramic matrix composite. An assembly tube surrounds the tubular cladding, and a collar is positioned between the tubular cladding and the assembly tube. The collar extends circumferentially around the cladding and comprises the ceramic matrix composite. The tubular cladding may be centered within the assembly tube by the collar.
Claims8
An assembly for nuclear applications, the assembly comprising:
- a tubular cladding for containing nuclear fuel, the tubular cladding comprising a ceramic matrix composite and a plurality of cladding tubes positioned end-to-end and bonded together;
- an assembly tube surrounding the tubular cladding;
- and
- a collar disposed between the tubular cladding and the assembly tube, the collar extending circumferentially around the cladding and comprising the ceramic matrix composite, wherein the collar is in contact with the assembly tube and provides a standoff between the tubular cladding and the assembly tube, said standoff resulting in a longitudinal gap extending between the tubular cladding and the assembly tube, wherein the collar is positioned at a joint between ends of at least two cladding tubes of the plurality of cladding tubes, the at least two cladding tubes being positioned end-to-end, and wherein the collar comprises one or more radially-inward projecting extensions positioned within the joint.
