摘要： Nuclear fuel assemblies include fuel elements that are sintered or cast into billets and co-extruded into a spiral, multi-lobed shape. The fuel kernel may be a metal alloy of metal fuel material and a metal-non-fuel material, or ceramic fuel in a metal non-fuel matrix. The fuel elements may use more highly enriched fissile material while maintaining safe operating temperatures. Such fuel elements according to one or more embodiments may provide more power at a safer, lower temperature than possible with conventional uranium oxide fuel rods. The fuel assembly may also include a plurality of conventional UO2 fuel rods, which may help the fuel assembly to conform to the space requirements of conventional nuclear reactors.

摘要： The present invention provided a method of manufacturing a duct for a gas turbine engine or the like from sheet metal material; the method comprising the steps of: fabricating a duct from sheet material (10,12,14) including rolling or folding metal sheet along ruled lines to form a ruled surface geometry approximately corresponding to at least part of a desired irregular final duct geometry; welding corresponding rolled or folded parts of the duct skin together and positioning the duct on a heat treatment fixture (30) having a shape corresponding to the said desired irregular duct geometry; the material of the heat treatment fixture having a greater thermal expansion coefficient than the duct material; heating the duct and fixture substantially to a stress relieving temperature of the duct material such that differential thermal expansion of the duct and fixture at the said stress relieving temperature causes the duct to distort and adopt the shape of the exterior surface of the fixture on which the duct is located.

摘要： The present invention provides a cladding having an outer circumferential substrate, a zirconium barrier layer metallurgically bonded to the inside surface of the substrate and an inner circumferential liner metallurgically bonded to the zirconium barrier. The inner circumferential liner is more ductile than conventional Zircaloy. The low ductility of the inner circumferential liner is obtained by using a zirconium alloy containing a low tin content (e.g. less than 1.2% by weight) and/or a low oxygen content (e.g. less than 1000 ppm). The inner circumferential liner is less than about 25 micrometers thick.
摘要翻译：本发明提供了一种具有外周基板，冶金结合到基板的内表面的锆阻挡层和与锆阻挡层冶金结合的内周衬套的包层。内周衬套比常规Zircaloy更具延展性。通过使用含有低锡含量（例如小于1.2重量％）和/或低氧含量（例如小于1000ppm）的锆合金，可获得内周衬套的低延展性。内周衬垫的厚度小于25微米。
