| Number | Title | Issue Date |
| 6327324 | Nuclear fuel assembly A fuel assembly for a boiling water reactor comprising a plurality of fuel units (3a, 3b, 3c, 3d), stacked on top of each other, each one comprising a top tie plate (5), a bottom tie plate (6) and a plurality of fuel rods (4a, 4b, 4c) arranged between the... | 12/04/2001 |
| 5362426 | Nuclear fuel pellets and method of manufacturing the same The present invention provides improved nuclear fuel pellets having high thermal conductivity for use in an LWR. This can be achieved by creating a continuous deposition phase of high-thermal conductivity substances in the grain boundaries in the pellets.... | 11/08/1994 |
| 5349618 | BWR fuel assembly having oxide and hydride fuel A boiling water nuclear reactor used for the production of electricity includes fuel rods and an assembly of these fuel rods that improve the reactor economics and safety. The fuel assemblies include hydride fuel pellets at selected axial and radial posit... | 09/20/1994 |
| 5219519 | Increased fuel column height for boiling water reactor fuel rods A fuel bundle is disclosed in which interspersed part length fuel rods define between the end of the fuel rods and the upper tie plate void regions which are not otherwise occupied. Full length fuel rods adjacent to these regions are provided with an expa... | 06/15/1993 |
| 4963317 | High loading uranium fuel plate Two embodiments of a high uranium fuel plate are disclosed which contain a meat comprising structured uranium compound confined between a pair of diffusion bonded ductile metal cladding plates uniformly covering the meat, the meat having a uniform high fu... | 10/16/1990 |
| 4814137 | High performance reliability fuel pellet A fuel pellet for a nuclear reactor fuel rod is fabricated with smooth and gently sloping surfaces having no sharp edges or areas of high stress concentration. The bearing surfaces of the fuel pellets are contoured so that the pellets are easily stacked w... | 03/21/1989 |
| 4652424 | Extended life nuclear control rod A control rod for a nuclear fuel assembly has structures formed of boron carbide mounted inside it. The boron carbide structures are provided deformable members between them which will deform at operating temperatures to accommodate the dimensional increa... | 03/24/1987 |
| 4175002 | Nuclear fuel pellet with oppositely bottomed holes A nuclear fuel pellet is made of a sintered, ceramic nuclear fuel mass and has a cylindrical configuration with a pair of opposite bottomed holes centrally provided one at each end. The bottomed holes are convergent toward their bottoms and each have a U-... | 11/20/1979 |
| 4131511 | Nuclear fuel element A nuclear fuel pin is formed of an elongated metallic tube, closed at each end, containing stacked fuel pellets and material including little, or no, fissionable material, and formed into porous, or bubbled, microspheres placed in the annulus between the ... | 12/26/1978 |
| 4129477 | Axially alignable nuclear fuel pellets The invention is directed to an axially alignable nuclear fuel pellet of the type stacked in end-to-end relationship within a tubular cladding. Experience has shown that fuel cladding failures can occur at pellet interface locations due to mechanical inte... | 12/12/1978 |
| 3963566 | Nuclear fuel column retainer A barrier member fixed in the end of a fuel column retaining spring to prevent contact between the retaining spring and the adjacent end plug of the fuel element whereby contamination of the weld between the cladding tube and end plug with retaining sprin... | 06/15/1976 |
