Two processes are being developed, to produce a solid actinide compound, at the head of the fabrication line, having practically the right, desired preform : these are the sol–gel process, using internal gelation, to form spherical actinide kernels(coated particle concept) ; andoxalic coprecipitation, to form a solid solution of actinides(pellet, or cylindrical pellet concept). 2, record 14, English, - actinide%20co%2Dconversion

Solid pellets are used in most PWRs [pressurized water reactor] and annular pellets are used in AGRs [advanced gas reactor]. Annular pellets have a cylindrical hole running through the centre of the pellet and thus require a retractable pin in the press. The purpose of this hole is to accommodate distortions in the fuel and fission gasses formed in the reactor. Once the pellets have been pressed, they are sintered at 1750°C in a reducing atmosphere of hydrogen or a mixture of hydrogen and nitrogen... 1, record 17, English, - annular%20pellet

Confinement des produits de fission. Le dioxyde d'uranium conserve dans sa structure 95 % des produits de fission. La plupart des produits de fission libérés proviennent de la région chaude au coeur de la pastille. Ils se diffusent par les fissures dans la partie plus froide des pastilles et s'échappent dans les cavités entre les pastilles. Une partie des substances libres s'échappera si le crayon de combustible se brise. 1, record 25, French, - confinement%20des%20produits%20de%20fission

[This figure] shows the design chosen for a CANDU fuel bundle. This bundle, used in all routine fuelling of CANDU reactors, is called CANLUB fuel.... The bundle... is mostly uranium dioxide(UO2), sheathed and held together by zircaloy. Zircaloy 4, the specific alloy used for this purpose, is 98% zirconium and 1. 7% tin. The UO2 is in the form of high-density pellets. Each fuel element is a thin zircaloy tube, the fuel sheath, filled with fuel pellets. A thin lubricating layer of graphite between the pellet and the sheath is what gives the fuel the proprietary name CANLUB. 1, record 26, English, - CANLUB%20fuel

On peut voir [...] la grappe de combustible conçue pour l'alimentation ordinaire des réacteurs CANDU : le combustible CANLUB. [...] La grappe [...] est principalement composée de dioxyde d'uranium (UO2) confiné dans une gaine de zircaloy. Le zircaloy 4, l'alliage utilisé dans le combustible CANLUB, est composé de 98 % de zirconium et de 1,7 % d'étain. Le UO2 se présente sous la forme de pastilles très denses. Chaque crayon de combustible est formé d'un tube mince de zircaloy - la gaine de combustible - rempli de pastilles de combustible. Le nom de marque du combustible, CANLUB, provient de la mince couche lubrifiante de graphite entre la pastille et la gaine. 1, record 26, French, - combustible%20CANLUB

Densified Pellet Technology. Pellets are dried ground wood or other biomass waste compressed into small cylinders about 6 mm(1/4 in.) in diameter and 25 mm(1 in.) long. The pressure and heat created during their production binds the pellets together without the need for additives. Pellet-burning appliances include a hopper to hold at least 20 kg of fuel and a screw auger to move the pellets from the hopper into the combustion chamber. Pellets usually burn cleanly because they are fed to the combustion chamber at a controlled rate and are matched with the right amount of combustion air. These appliances are generally able to operate at lower emission levels than natural firewood appliances. 2, record 27, English, - densified%20pellet

The basic materials for most reactor fuel elements are of three types: metallic fuels contain uranium metal or uranium metal alloys; ceramic fuels are sintered compacts of uranium compounds such as uranium dioxide and uranium carbide; and cermets are dispersions of uranium compounds in a metal matrix. 2, record 28, English, - sintered%20pellet
