🔶Finland on the verge of launching the world’s first permanent nuclear waste repository

Finland has issued an operating license for the world’s first permanent repository for spent fuel from nuclear power plants. Posiva, the company responsible for disposing of Finland’s nuclear waste, announced on October 22, 2026 that these underground facilities in the Eurajoki region, in the south-west of the country, will soon begin operations.

A permanent nuclear waste repository is a facility designed for the permanent storage of radioactive materials produced by the operation of nuclear power plants. In these facilities, spent fuel is placed in robust containment canisters and buried deep underground in stable rock layers. The purpose of this method is to contain radioactive materials and prevent their release into the environment for very long periods.

Ilkka Pöykköläinen, CEO of Posiva, described the issuance of the operating license as a “great and historic day” for the company and Finland. However, before final disposal of the spent fuels begins, the company must carry out the necessary tests and inspections; these steps must be reviewed and approved by the Finnish Radiation and Nuclear Safety Authority.
