Název v původním jazyce

Neutron radiation effect on concrete mesoscale samples and concrete structures

Popis výsledku v původním jazyce

Nuclear power plants’ need to extend the service life of facilities raises the question of the current state of concrete structures. The main goal of this paper is to present the ability of numerical modelling of reinforced concrete structures to capture the main deteriorating effect of neutron radiation on concrete material properties, which is radiation-induced volumetric expansion (RIVE) of aggregate. Firstly, the mesoscale samples representing actual experiment, Kelly (1969), are modelled, and the comparison with actual experimental results shows good correlation. Secondly, the RIVE impact on the performance of the actual biological shield is studied assuming the maximal RIVE of concrete samples reported in literature, Field et al. (2015).
