    Abstract

    The effect of high dose irradiation on irradiation growth in zirconium commercial Zr-1%Nb, Zr-2.5%Nb, Zr-1%Nb-1.3%Sn-0.4%Fe alloys at temperatures of ∼80 and 320–360°C has been investigated.

    It is shown that the irradiation growth strain in Zirconium and Zr-Nb alloys as a function of neutron fluence sharply increases at fluences higher than (2–3)×1026 m-2 (E>0.1 MeV). Zr-1%Nb-1,3%Sn-0,4%Fe alloy was observed to exhibit radiation growth at high neutron fluences.

    One of the methods to reduce anisotropy of properties and dimensional changes under irradiation is fast high-frequency treatment (FHF) consisting in quenching from beta-phase following quick heating with exposure.
