In situ rock stress-strength comparison: Posiva's Olkiluoto Spalling Experiment (POSE)

摘要

After the Finnish Government's favourable policy decision in 2001, Posiva Oy has focused further investigations at the Olkiluoto site, western Finland and has started in 2004 the construction of an underground characterisation facility termed the 'ONKALO'. The ONKALO construction will be continued until 2012. The findings of the ONKALO will provide the knowledge needed for an application, supported by a Preliminary Safety Assessment, and to construct a final repository for spent nuclear fuel. Posiva will submit an application for the construction licence by the end of 2012. The target is to begin disposal operations in 2020.
