The Onkalo nuclear waste disposal facility under construction in Olkiluoto, Finland, will be the world’s first permanent geological repository for spent nuclear fuel and high-level radioactive waste. Posiva is using a Scanclimber hybrid hoist-work platform SC2000 in assembly work inside the personnel shaft in Onkalo. The product was custom-built according to Posiva’s requirements. The SC2000 hoist-work platform is a hybrid of a hoist and a mast climber (MCWP).
