Full-scale High Level Waste
Engineered Barriers (FEBEX)
FEBEX I - Mock-up Test |
|
The "mock-up" test was conducted in the facilities of
CIEMAT (Madrid, Spain). The physical components of the test consist
of five basic units: the confining structure, with its hydration
system; the heating system; the clay barrier; the instrumentation;
and the systems for data acquisition and for heater control.
Predictive modelling has been carried out on THM and THG behaviour
during the pre-operational stage, along with modelling during the
operational stage and contrasting with the test monitoring values.
