ONKALO, the underground rockcharacterisation facility excavated in the Olkiluoto bedrock, will reach its final disposal depth in June.
26.03.2010 Posiva signs a contract on the ONKALO tunnel project with Destia Oy
Posiva has signed a contract with Destia Oy on further contracting related to ONKALO. The work comprises excavation of the access tunnel down to the level of technical facilities at the depth of 437 metres, and testing and demonstration facilities built at the final disposal depth (420 m). It is estimated that the project will be completed in spring 2011.
In its research and development work, Posiva Oy, responsible for the final disposal of its owners' spent nuclear fuel, aims to submit, in 2012, a construction license application pursuant to the Nuclear Energy Act for a final disposal facility. The development work dealing with the final disposal's technical barriers (metal canister, bentonite buffer, tunnel backfill material) has progressed far, and ONKALO, an underground characterisation facility excavated in Olkiluoto, will reach the final disposal depth (420m) during the spring.
14.12.2009 ONKALO has been excavated for four kilometres
The access tunnel of the characterisation facility ONKALO, excavated into the bedrock of Olkiluoto, has advanced for four kilometres to a depth of almost 400 metres. The planned final disposal depth - 420 metres - will be reached at the beginning of next year. At that point, the application of the excavation technique and methods in the final disposal facilities will be examined.
