Excavation of a deep geological repository – for final disposal – at Olkiluoto began in May and is a world first. Not even the U.S., with its waste from over 130 nuclear reactors built since the 1950s, has committed to one. James Conca looks at Finland’s history of nuclear waste disposal, how it got to this decision, and the disposal method. The repository tunnels will total a length of about 35 kilometres and will cost €2.6bn ($3.4bn). Nuclear from four plants accounts for 32% of Finland’s electricity. A fifth unit is almost completed and will lift that figure to 60%, completely replacing their coal generation. And some cities are considering the use of small modular reactors to provide district heating. It all amounts to Finland’s clear signalling that nuclear is a big part of its clean energy future.
