摘要:
The present invention provides an aluminum composite material having neutron absorbing power that improves the ability to absorb neutrons by increasing the content of B, while also being superior to materials of the prior art in terms of mechanical properties and workability. The aluminum composite material having neutron absorbing power contains in Al or an Al alloy matrix phase B or a B compound having neutron absorbing power in an amount such that the proportion of B is 1.5% by weight or more to 9% by weight or less, and the aluminum composite material has been pressure sintered.
摘要:
A basket has a lattice-like section for accommodating individual used nuclear fuel in predetermined positions in a cask. The basket is made from aluminum composite material having good neutron absorption ability, excellent mechanical property and workability. The aluminum composite material is made by having, in an Al or Al alloy base phase, B or B compound with a neutron absorption ability and an additive element, e.g. Zr or Ti, for giving a high strength property, and subjecting to a sintering under pressure.
