    • The invention concerns a new process and mould assembly for use in aluminothermic intercast welding of rail ends to form substantially continuous railway tracks, the process comprises the steps of aligning the to-be-welded rails (6) so as to define an inter-rail gap between the rail ends (6); providing a mould assembly comprising two upright side moulds (12) that are fitted on either side of the inter-rail gap, each side mould (12) including at least one elongate, open-ended down gate (18) extending between a top part and a bottom part of the side mould (12) and terminating in a down gate well; a base mould (14) adapted for receiving the rail ends (6) and for supporting the side moulds (12) on either side of the inter-rail gap; the arrangement being such that the base mould(14) and side moulds (12) cooperate to define an enclosed mould cavity for receiving molten weld material; and receiving means (16) for receiving molten weld material in at least one of the side moulds (12) and arranged in flow communication with the down gate (18); and side-pouring molten weld material into the receiving means (16) such that the molten weld material is transported from the receiving means (16), down the down gate (18) of the side mould (12) and into the base mould (14) to form a rail foot, from where the molten weld material rises into the inter-rail gap to form the web and rail head of the rail weld.

    • The invention relates to the confinement of an alloy formed of actinide transuranic radioactive wastes and beryllium metal within a neutron moderating and reflecting apparatus to cause accelerated destruction (burning) of the actinide wastes. Waste actinides, including plutonium, neptunium, americium, and curium, emit alpha particles by radioactive decay. The alpha particles are converted into neutrons by the beryllium through an alpha-neutron (alpha, n) reaction. The neutrons developed by the alpha, n reaction are moderated by a surrounding layer of graphite, which allows the slowed neutrons to cause additional fission or decay events within the waste actinide alloy. This process is passive because the alpha particles that initiate the actinide burning are an intrinsic physical property of the actinides. The burning or decay process is accelerated because neutrons that would ordinarily escape the confinement fixture (a Standard Source capsule) are reflected back into the actinide waste, transmuting them into heavier, less stable isotopes that decay more rapidly. The use of the moderator/reflector material allows the waste actinides to be destroyed in a 10,000-year repository period instead of requiring one million years to attain the same waste reduction by natural radioactive decay alone. Beryllium may also be used as a neutron moderator/reflector, but is not a cost effective choice for large scale use.
    • 本发明涉及由锕系非铀放射性废物和铍金属形成的合金在中子调节反应装置内的限制,以引起锕系废料的加速破坏(燃烧)。 废锕系元素,包括钚,ium,ium和ium,都会通过放射性衰变而释放出α粒子。 通过α中子(α,n)反应,α粒子被铍转化成中子。 由α,n反应产生的中子由周围的石墨层调节,这允许减慢的中子在废锕系合金中引起额外的裂变或衰变事件。 该过程是被动的,因为引发锕系元素燃烧的α粒子是锕系元素的固有物理性质。 燃烧或衰减过程加速,因为通常会逃离约束固定装置(标准源胶囊)的中子被反射回锕系废物,将其转化成更重,更不稳定的同位素,其衰减更快。 使用调节剂/反射器材料可以使废弃锕系元素在10,000年的储存期内被销毁,而不需要一百万年才能通过天然放射性衰变来实现相同的废物减少。 铍也可用作中子调节剂/反射器,但不是大规模使用的成本有效的选择。
