    摘要： There is disclosed a radiation stable shield for use in space or high altitude applications. The shield comprises a plurality of overlapping planar glass flakes which are held in a lamellar matrix of flexible polymeric material. The flakes are each formed of a radiation stable glass which is suitale for use in space or high altitude applications. The flakes are arranged in alignment with the lamellar direction of the matrix.

    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.
