The Finnish Reactor 1 (FiR1) research reactor at Aalto University's Otaniemi campus in Espoo has been successfully decommissioned, becoming the first nuclear reactor to undergo this process in Finland. The decommissioning of the water-cooled, pool-type TRIGA Mark II research reactor, which began operation in 1962, was completed by Fortum after receiving the contract in April 2020. The project, costing around EUR24 million, involved transferring used fuel to the USA, dismantling the reactor, and disposing of waste at the Loviisa nuclear power plant's repository. VTT and Fortum gained valuable experience from this project, which will be used to support future decommissioning efforts and service business customers. The decommissioning of FiR1 has set a model for decommissioning commercial nuclear reactors in Finland and has contributed to the development of expertise in this field. The project also served as a test platform for applicable technologies and led to the successful export of technology.
