THE MANUFACTURE OF CONTROL RODS IN THE ASEA NUCLEAR POWER DEPARTMENT
BS>The method by which control rods were manufactured for the Agesta pressurized water reactor in Sweden and the Halden boiling water reactor in Norway is described. For physical and metallurgical reasons, an alloy of silver together with l5% indium and 5% cadmium was selected for the Agesta reactor and an alloy of silver with 30% cadmium for the Halden reactor. Because of mechanical strength deficiencies, the neutron absorbing silver alloys were clad with stainless steel. The cladding of the Agesta rods was metallurgically bonded to the neutron absorbing silver alloy. As a preliminary stage to bonding, those surfaces of the stainless steel cladding tubes which were to come into contact with the silver alloy were activated and then consecutively nickel and copper plated. The steel tubes for the Halden control rods were thoroughly cleaned by degreasing and pickling before compound drawing. (P.C.H.)
