Construction of test disposal tunnel under way at Onkalo : Waste & Recycling - World Nuclear News: ​Finnish radioactive waste management company Posiva Oy has announced  that work to excavate a final disposal tunnel has started at the Onkalo underground characterisation facility near Olkiluoto. The tunnel is for the 'joint functional test', which involves small-scale final disposal under actual conditions, and is part of commissioning the geological repository. The joint functional test can be used to demonstrate that the processes and procedures related to final disposal are in order and, only then, can the disposal facility be granted an operating licence.
