VTT and Fortum to decommission a VTT’s FIR 1 reactor

17 April 2020

VTT and Fortum have agreed on a partnership to decommission VTT’s FIR 1 research reactor and nuclear power plant construction materials laboratory in Otaniemi, Espoo. The agreement gives VTT access to Fortum's long experience in nuclear power plant operation and nuclear waste management. Fortum will draw up the plans, dismantle the reactor and dispose of any nuclear waste. VTT is responsible for the safety of the reactor, the laboratory and the decommissioning process and for securing any necessary permits. 

VTT has already applied to the Finnish Government for permission to decommission the reactor and expects to get the go-ahead before the end of 2020. All of the spent nuclear fuel must be removed from the premises before the reactor can be dismantled. VTT’s primary goal is to return the fuel to the United States, which supplied the fuel in the first place. Another alternative is to use an interim storage facility until a geological disposal site is available in Finland. The dismantling process is scheduled for the years 2022–2023.
