    • A nuclear reactor includes a reactor pressure vessel and a nuclear reactor core comprising fissile material disposed in a lower portion of the reactor pressure vessel. The lower portion of the reactor pressure vessel is disposed in a reactor cavity. An annular neutron stop is located at an elevation above the uppermost elevation of the nuclear reactor core. The annular neutron stop comprises neutron absorbing material filling an annular gap between the reactor pressure vessel and the wall of the reactor cavity. The annular neutron stop may comprise an outer neutron stop ring attached to the wall of the reactor cavity, and an inner neutron stop ring attached to the reactor pressure vessel. An excore instrument guide tube penetrates through the annular neutron stop, and a neutron plug comprising neutron absorbing material is disposed in the tube at the penetration through the neutron stop.

    • An elastomeric matrix impregnated with at least 70% by weight of a high atomic number radiopaque substance, and cured with an organic peroxide, to form carbon-carbon links between elastomer molecular chains. The radiopaque elastomeric matrix may be used to create a flexible, lightweight, carbon-carbon linked, multilaminated protection material against ionizing radiation. The multilaminated protection material may include a mechanical reinforcement cloth layer to avoid material expansion or rupture; and additional external elastomeric layers for protection against aging, physical, biological and chemical hazards, as well as allowing mechanical memory of the material and easy cleaning, desinfection and sterilization. These layers are directly merged or incorporated into a single, fused sheet with the radiopaque elastomeric matrix, without the use of glues or adhesives, during a cure and pressure application wherein the elastomer molecules create reticulated carbon-carbon links between the internal and external elastomeric layers and through the pores of the reinforcement layer. The multilaminated material allows production of colored, flexible, lightweight, durable radiation protection articles for medical, dental, and industrial uses.
    • 用至少70重量%的高原子序数不透射线物质浸渍并用有机过氧化物固化的弹性体基体,以在弹性体分子链之间形成碳 - 碳连接。 不透射线的弹性体基质可用于产生抵抗电离辐射的柔性,重量轻的碳 - 碳连接的多层保护材料。 多层保护材料可以包括机械加强布层以避免材料膨胀或破裂; 以及额外的外部弹性体层,用于防止老化,物理,生物和化学危害,并允许材料的机械记忆和易于清洁,消毒和灭菌。 在固化和压力应用期间,这些层直接并入或并入到具有不透射线弹性体基体的单个熔融片材中,而不使用胶水或粘合剂,其中弹性体分子在内部和外部弹性体层之间形成网状碳 - 碳连接 并通过加强层的孔。 多层材料允许生产用于医疗,牙科和工业用途的有色,柔性,轻质,耐久的防辐射制品。

    • Gegenstand der Erfindung ist es, eine Strahlenschutzwand (1) zu schaffen, welche die vollständige Wiederverwendung von nicht mehr benötigten Bildröhrengläsern ermöglicht. Mit einfachen Mitteln soll dabei eine stabile, raumteilende große Wand realisierbar sein, die gleichzeitig transparente bis opake Eigenschaften hat. Die Strahlenschutzwand (1) ist mit aus Recycling-Bildröhrenglasgranulat erschmolzenen transparenten bis opaken Platten (3) zu einem Mauerverband (2) gefügt. Die transparenten bis opaken Platten (3) sind an den Fugen (4) geklebt oder in einem Tragrahmen (5) eingelegt oder eingeklebt. Die erfindungsgemäße Strahlenschutzwand ist vorzugsweise zum Abschirmen von schwach energetischer Strahlung wie Röntgen-Strahlung geeignet. Durch die Erfindung soll es ermöglicht werden, Gläser aus Elektronenstrahl-Bildröhren, welche nicht mehr im Gebrauch sind, einer wirtschaftlichen und umweltgerechten Wiederverwendung zuzuführen.
