    摘要： This invention relates to a shielding material used as a radiation shield of a container containing radioactive wastes. A radiation shield with an excellent heat-transferring property is fabricated from composite particles (A) obtained by coating core particles (a) of radiation-shielding property with a metal (b) of high thermal conductivity. Composite particles are formed into a certain shape of radiation shield by hot-press forming or other forming or packed into the internal space of radioactive waste container or the shield container cavity to compose a radiation shield.

    摘要： A neutron absorbing article, preferably in flat plate form and suitable for use in a storage rack for spent nuclear fuel, includes boron carbide particles, diluent particles and a solid, irreversibly cured phenolic polymer cured to a continuous matrix about the boron carbide and diluent particles. The total content of boron carbide and diluent particles is a major proportion of the article and the content of cured phenolic polymer present is a minor proportion. By regulation of the ratio of boron carbide particles to diluent particles, normally within the range of 1:9 to 9:1 1 and preferably within the range of 1:5 to 5:1, the neutron absorbing activity of the product may be controlled, which facilitates the manufacture of articles of particular absorbing activities best suitable for specific applications.

    摘要： Radiation shields (20) include an outer composite wall (22), an inner composite wall (24), and an enclosed fuel chamber (28) disposed between the inner and outer composite walls. A fuel may be contained within the enclosed fuel chamber (28). Spacecraft include one or more such radiation shields (20), and may further include a fuel cell (80) and a conduit (50) providing fluid communication between the fuel chamber (28) of the radiation shield (20) and the fuel cell (80). Methods of forming a radiation shield system include forming an enclosed fuel chamber between an outer composite wall and an inner composite wall of a radiation shield, and providing fuel within the enclosed fuel chamber.

    摘要： The invention relates to a radiation shielding construction for beam-guiding devices (28) of a particle accelerator and/or irradiation sites on a particle accelerator, comprising: a load-bearing housing (23) having concrete walls as side walls (14, 16), ceilings (18) and/or floors (10), wherein the concrete walls form a first radiation shielding layer, a second radiation shielding layer (20) comprising a loose or compacted filler mass, particularly soil, at the outside of at least some of the concrete walls, wherein the filler mass is pervious to water to a certain degree so that radionuclides could be flushed from the filler mass, wherein the concrete walls and the second radiation shielding layer (20) comprising the loose or compacted filler mass form an at least double-layer radiation shielding arrangement, and a sealing film (24) for the second radiation shielding layer (20), wherein the sealing film (24) surrounds and delimits the second radiation shielding layer (20) comprising the loose or compacted filler mass on the outside of the second radiation shielding layer (20), wherein the loose or compacted filler mass of the second radiation shielding layer (20) is enclosed between the concrete walls and the sealing film (24) in a water-proof manner, thereby immobilizing the filler mass hydro-geologically.
