Gallery & Crossing test seal test Heater test THE PRACLAY EXPERIMENT Research into the impact of heat-emitting waste on Boom clay The high-level radioactive waste produces heat and during disposal will temporarily cause the clay around the disposal galleries to warm up. The PRACLAY experiment is a large-scale experiment that studies the effect of this heat on the deep clay layer. At the same time, it wants to investigate how excavations influence the behavior of the clay layer. This knowledge is essential to determine how the realization of a repository can influence the favorable properties of the clay to contain the radioactive waste. Certainty about the preservation of these properties is necessary to confirm that the disposal of heat-emitting high-level radioactive waste in a deep clay layer can be a safe solution in the long term. The PRACLAY experiment is carried out on a large scale, in the long term and at temperatures expected in the eventual disposal of highly radioactive waste. Film about the PRACLAY Heater experiment The PRACLAY experiment proceeds in several phases: Phase 1 : Construction of the PRACLAY gallery (2007) Phase 2 : Installation of the heating system and closure of the PRACLAY gallery (2008-2011) Phase 3 : Heating phase (from 2014) ABOUT EURIDICE Organization Contact CONTEXT Geological storage in clay Role of EURIDICE THE LABORATORY Virtual visit Construction of HADES At work in HADES RESEARCH Behavior of clay Excavation and Construction Instrumentation and monitoring PRIVACY DECLARATION site map We use cookies on this site to improve your user experience We use analytical cookies to measure website usage, identify problems and optimize your user experience.
