SILVER ALLOY CONTAINING INDIUM AND CADMIUM FOR MAKING NEUTRON-ABSORBING ELEMENTS, AND USE THEREOF

摘要

An alloy containing, in atomic %, 9-12 % indium and 4-5.35 % cadmium, the balance being silver and tiny amounts of unavoidable impurities. The alloy preferably contains 9-10 % indium and 4.35-5.35 % cadmium. Said alloy may be used in the form of pellets or rods placed in a tubular sleeve to form a neutron-absorbing element of a reactivity adjustment cluster in a pressurised water nuclear reactor.
