摘要: Water saturation is a key factor to assess the safety of concrete storage structures of radioactive waste. Our laboratory has developed a nondestructive method of measuring the in situ water saturation. A pulse sensor, designed to measure effective gas permeability, is firstly casted in the concrete structure. The in situ gas permeability is then periodically measured by analyzing the gas flow rate through the pulse sensor. The relationship between relative gas permeability and liquid saturation of the same material is …
