B4C/Al中子吸收板腐蚀过程中的起泡研究
Study on the Blistering of B4C/Al Neutron Absorber Plate in the Course of Corrosion
摘要
Abstract
The corrosion model of cladding blistering on B4C/A1 neutron absorber plate was established by Henry's law, and by means of the model to investigate the relationship between pore radius and temperature factors for blistering. Influence of pore size for the neutron absorber plate blistering was analyzed by using the pore capillary effects. The results show that the hydrogen pressure produced in small radius pores is higher due to Al corrosion, which contributed to B4C/A1 neutron absorber plate cladding blistering. Influence of temperature on the corrosion generated hydrogen pressure is very small, but the main factors affecting the hydrogen pressure is the pore radius sizes. Blistering power of the cladding is hydrogen continuous generation and accumulating in the pore capillary. The water diffuses easily through the pore capillary in B4C/A1 cores, which will cause the cladding blistering because of Al corrosion.关键词
