    OverviewCommon physical forms of nuclear fuelOxide fuelMetal fuelNon-oxide ceramic fuelsLiquid fuelsLess-common fuel formsAccident tolerant fuels

    Uranium dioxide (UO2) powder is compacted to cylindrical pellets and sintered at high temperatures to produce ceramic nuclear fuel pellets with a high density and well defined physical properties and chemical composition. A grinding process is used to achieve a uniform cylindrical geometry with narrow tolerances. Such fuel pellets are then stacked and filled into the metallic tubes. The metal used for the tubes depends on the design of the reactor. Stainless steel was used in the past, but most reactors no

  • Nuclear fuel cycle - Wikipedia

    The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end, which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in the back end, which are necessary to safely manage, contain, and either reprocess or dispose of ...

  • Nuclear Fuel Processing Systems - Harper Intl

    During nuclear fuel pellet production there are several operations that produce waste, including swarf from pellet grinding operations and broken pellets. These waste products are oxidized from UO2 to U3O8. This material is then re-introduced into the production of nuclear fuel.
