POPLU concrete precasting is done. A few concrete batches has been casted above surface conditions in order to study the properties of low pH concrete developed for POPLU plug experiment.
Extensometers has been emplaced nearby POPLU Experiment tunnel for monitoring of rock deformations. In addition the rock temperature and moisture are monitored atomatically.
The core drilling of POPLU monitoring boreholes is precise enough method to produce smooth holes. Work has been finished.

The excavation of demonstration tunnels for POPLU Experiment starts in August 2013. These two tunnels will be excavated with drill and blast method with similar size and specifications which has been determined for Posiva deposition tunnels.
Please find a link to the Posiva site, were POPLU Experiment and DOPAS project are shortly presented.
The pilot holes for RSC work has been cored in the planned tunnel locations in January 2013. According to the preliminary rock suitability classification (Spring 2013) a proper place for plug can be found. The exact location will be confirmed after excavation of tunnels.
