Construction and Operational Experiences of Engineered Barrier Test Facility for Near Surface Disposal of LILW

Engineered barrier test facility is specially designed to demonstrate the performance of engineered barrier system for the near-surface disposal facility under the domestic environmental conditions. Comprehensive measurement systems are installed within each test cell. Long- and short-term monitoring of the multi-layered cover system can be implemented according to different rainfall scenarios with artificial rainfall system. Monitoring data on the watercontent, temperature, matric potential, lateral drainage and percolation of cover-layer system can besystematically managed by automatic data acquisition system. The periodic measurement data are collected and will beanalyzed by a dedicated database management system, and provide a basis for performance verification of the disposal cover design.
