Abstract
Posiva Oy has established a monitoring program that
ensures the applicability of the constructed facilities
to the final disposal of nuclear waste and the long-term
capacities of engineered barrier systems. A monitoring
system for a full-scale demonstration is installed to a
tunnel end plug being built in a demonstration tunnel in
the bedrock of Olkiluoto in Finland. The concrete plug
will be instrumented with sensors continuously measuring
displacements, strain, humidity, total and pore pressure
and temperature. Further sensors will allow for
monitoring the pressure being applied in a filter layer
behind the plug and the observation and control of the
main parameters needed during the pressurization of the
structure by pumping water behind the plug. The general
idea is to carefully measure the amount and pressure of
incoming water in order to analyze the performance of
sealing mechanisms of the structure. The out-flowing
leakage and in-pumped water will also be determined by a
monitoring system.
