    • A system (100) for measuring mechanical strain. The system comprises a main spring (113) and a connecting piece (114) both with an open concave cross-section, the connecting piece is rotatable mountable inside the main spring at a fixing point (117), such that the respective open concave cross-sections are in the same plane and the open parts are oriented in the same direction. The legs of the main spring (113) are connectable with the specimen shoulders for applying the tips of the measuring arms onto the gauge length of the specimen. Measuring arms (123, 124) are rotatably mountable on the legs of the connecting piece (114) so as to push against the specimen when mounted and so as to rotate when the measured object is subject to strain.
    • 一种用于测量机械应变的系统(100)。 该系统包括主弹簧(113)和连接件(114),两者具有敞开的凹入横截面,连接件可在固定点(117)的内部可旋转地安装在主弹簧的内部,使得各自的开口凹交叉 截面在相同的平面上,开放部分朝向相同的方向。 主弹簧(113)的腿可与试样肩部连接,用于将测量臂的尖端施加到试样的标距上。 测量臂(123,124)可旋转地安装在连接件(114)的腿部上,以便在安装时推靠在试样上,并且当所测量的物体受到应变时旋转。

    • A method is described for producing nuclear fuel products, the method comprising receiving metallic or intermetallic uranium-based fuel particle cores, providing at least one physical vapour deposited coating layer surrounding the fuel particle core and embedding the nuclear fuel particles in a matrix so as to form a powder mixture of matrix material and coated fuel particles. The at least one physical vapour deposited coating layer may comprise inhibitors of inhibiting, stabilizing and/or reducing interaction between metallic or intermetallic uranium-based fuel particles cores and the matrix wherein the fuel particles typically may be embedded. Alternatively or in addition thereto the deposited coating layer may comprise neutron poisons. The present invention also relates to coated fuel particles, fuel elements and the use of fuel particles for generating neutrons.
    • 描述了一种用于生产核燃料产品的方法,该方法包括接收金属或金属间铀基燃料颗粒芯,提供围绕燃料颗粒核心的至少一个物理气相沉积涂层,并将核燃料颗粒嵌入基体中,以便 形成基质材料和涂覆的燃料颗粒的粉末混合物。 所述至少一个物理气相沉积涂层可包含抑制,稳定和/或减少金属或金属间铀基燃料颗粒芯与基质之间的相互作用的抑制剂,其中所述燃料颗粒通常可被嵌入。 或者或除此之外,沉积的涂层可以包括中子毒素。 本发明还涉及涂覆的燃料颗粒,燃料元件以及燃料颗粒用于产生中子的用途。
