    摘要: Provided is a member for nuclear reactors capable of being stably used without swelling or creep deformation even if directly exposed to neutrons with no additional improvements in nuclear reactor operation conditions or devices. A member for nuclear reactors comprises a core section comprising an aggregate of graphite particulates and a covering layer comprising a dense body of ceramic covering the core section. Because graphite that is affected by neutron irradiation is used in a state of aggregation of particulates and is not mutually connected, the shape and dimensions of the member for nuclear reactors is not affected even if there is swelling, creep deformation, or the like. Moreover, this member for nuclear reactors has a covering layer comprising a dense body of ceramic covering the core section. Because the covering layer comprising the dense body is more durable than graphite with respect to neutron irradiation, the shape and dimensions of the member for nuclear reactors are unlikely to be affected.

    摘要: Die vorliegende Erfindung betrifft ein mehrschichtiges Strahlenschutzbauteil (1), bei dem zwischen wenigstens zwei Betonsrhichten (3, 4) wenigstens eine Strahlenschutzschicht (7) aus einer verdichteten Schüttung losen Strahlenschutzmaterials angeordnet ist. Erfindungsgemäß weist das Strahlenschutzbauteil (1) nun wenigstens eine Kurzzeit-Dynamik-Armierung auf und ist so ausgelegt, dass eine Volumenvergrößerung der Strahlenschutzschicht (7) bei Kurzzeit-Dynamik-Beiastung, insbesondere durch Beschuss, Explosion und/oder Erdbeben, ohne Versagen des Strahlenschutzbauteils (1) aufgenommen werden kann. Dabei weist die Kurzzeit-Dynamik-Armierung erfindungsgemäß wenigstens eine Betonarmierung und/oder eine Schüttungsarmierung auf. Zudem kann zwischen Strahlenschutzschicht (7) und den Betonschichten (3, 4) eine Entkoppelungsschicht (14) angeordnet sein, die der gezielten Einstellung der Reibung zwischen den der Schüttung und den Betonschichten (3,4) dient.

    摘要: The invention relates to a laminate including a decorative layer, a first resin impregnated core layer, a radiation barrier layer and a second resin impregnated core layer. The laminate prevents the penetration of radiation therethrough and may be used in the construction of ceiling and wall panels, flooring, furniture, fixtures, cabinet and door cladding, protective screens and other objects which will effectively prevent the passage of radiation from an isolated enclosure.

    摘要: The radiation shield has a shell (22) of a first radiation opaque material such as lead containing discrete components (23) for example rods or spheres of a second radiation opaque material such as tungsten of higher density than the first radiation opaque material within a radiation opaque medium (24) of lower density than the discrete components (23). The shell or casing (22) is manufactured from a material which is easily worked and formed into different intricate or complex shapes while the discrete components 23 provide the required high degree of shielding.

    摘要: A structure for shielding X-ray and gamma radiation, which is of laminated construction having at least n layers made of materials different from each other (11, 12, ... 1n), where n is higher than or equal to two, and each of the first n-1 layers (e.g. 12) comprises an element converting at least a part of the X-ray or gamma radiation to be shielded or, of the sec­ ondary radiation emitted by the preceding layer (e.g. 11), respectively, into an X-ray or gamma radiation the energy of which is obove the energy level defined by the K-edge of the next layer (e.g. 13).
