摘要： A vacuum arrangement has a vacuum pipe having a vacuum opening facing a ground surface and adapted to pick up from the ground surface a material to be collected. The vacuum pipe conveys the material to be collected into a collecting container connected to the vacuum pipe. The vacuum pipe has a working area located within the area of the vacuum opening. At least one blower nozzle having a blower air exit is arranged such that a blower air flow exiting from the blower air exit is directed onto the ground surface into the working area. The blower air exit and the vacuum opening are positioned at a spacing relative to one another.

摘要： Method for manufacturing sintered oxidic nuclear fuel bodies by molding uranium oxide starting powder, a mixture of uranium oxide and plutonium oxide starting powder or of uranium-plutonium oxide mixed-crystal starting powder to form blanks and by a heat treatment of these blanks with a U.sub.4 O.sub.9 or (U, Pu).sub.4 O.sub.9 crystal phase developed in them to a degree which can be crystallographically detected at a sintering temperature in the range of 1000.degree. to 1400.degree. C. in an oxidizing and subsequently in a reducing gas atmosphere. The starting powder and/or the blanks are preroasted at a roasting temperature below the sintering temperature in a roasting gas atmosphere with oxidizing action and with an oxygen potential in which the U.sub.4 O.sub.9 (U, Pu).sub.4 O.sub.9 crystal phase is developed and cooled down subsequently to a starting temperature below the roasting temperature in an inert or oxidizing cooling-down gas atmosphere. Starting from this starting temperature, the blanks are heated to the sintering temperature in an inert or oxidizing heating gas atmosphere while maintaining the U.sub.4 O.sub.9 or the (U, Pu).sub.4 O.sub.9 crystal phase.

摘要翻译： 通过模制氧化铀原料粉末，氧化铀和钚氧化物起始粉末或铀 - 钚氧化物混合起始粉末的混合物来形成烧结氧化物核燃料体的方法以形成坯料并且通过用U4O9热处理这些坯料 或（U，Pu）4 O 9结晶相在一定程度上可以在氧化并随后在还原气体气氛中在1000-1400℃范围内的烧结温度下进行晶体学检测。 起始粉末和/或坯料在具有氧化作用的焙烧气体气氛中的焙烧温度下焙烧，并且其中U4O9（U，Pu）4 O9晶相的氧电位被开发并随后冷却 在惰性或氧化冷却气氛中的起始温度低于焙烧温度。 从该起始温度开始，将坯料在惰性或氧化加热气体气氛中加热至烧结温度，同时保持U4O9或（U，Pu）4 O9晶相。
