POPLU mock up
POPLU mock up was casted underground at the depth of - 420 m in Demosntration area in ONKALO
Before actual emplacement of POPLU plug a mock
-up casting was done in July 2014. A mock up is used to confirm the concrete
specifications and ensure a good quality of final product. The mock up is
required for structures which are implemented as nuclear safety classified
components. POPLU Experiment will be
implemented with similar type of authority requirements as construction in real
repository, even it would not be necessary in this stage.
The mock up casting was done in miniature tunnel replica mould, which length is three
meter to observe the flow properties of concrete to be used in full scale
demonstration.
