Effects of Irradiation Damage on Electrochemical Property of Zircaloys

综述了堆内辐照对锆合金电化学性能影响的概况,浅析了堆内辐照损伤的机理,并重点探讨了主要的堆内辐照源———中子辐照对锆合金微观结构与氧化性能的影响。进一步阐述了堆外离子轰击模拟堆内中子辐照研究方法的进展概况,并就离子轰击实验参量的选择进行了较为深入的分析。

The electrochemical property of zircaloys is one of the most important factors that affect the safe function of nuclear reactor. To systematically study the influence of irradiation damage on the electrochemical property of zircaloys and grope for the new way to improve it, the survey of effects of irradiation-in-pile on the electrochemical property of zircaloys is offered, and the mechanism of irradiation damage in piles is studied. Influence of neutron irradiation, one main irradiation, on the microstructure and oxidation property of zircaloys, is emphasized. The method of simulation of neutron irradiation in piles by ion bombardment out of piles, is characterized by short time, low expense and no pollution. The development of this method is further described, and the means how to choose parameters of ion bombardment tests is more deeply analyzed.
