Current trends in the use of Zirconium Alloys

Moorthy, K Balarama (1969) Current trends in the use of Zirconium Alloys. In: UNSPECIFIED.



THE development of zirconium and its alloys for use in nuclear reactors began in the United Statesin 1948 when it was found that hafnium-free zirconium had a much lower neutron-absorption crosssection than had previously been suspected. Structural materials for use in water-cooled power reactors must possess a combination of high stre-ngth, corrosion resistance and low neutron capture cross-section. Zirconium alloys alone have the required combi-nation of these. For almost a decade the standard zirconium alloy for use in water-cooled reactors has been zircalov-2. A very considerable body of experience in the fabrication and use of zirconium alloys has been built up. It has been demonstrated that zircaloy tubes can be manufactured to specifications far more exacting in their requirements than is the case for standard code specifications for heat exchanger and condenser tubes.
