FiR 1 TRIGA Mark II research reactor, which was operated in Espoo, Finland, in 1962–2015 is nearing decommissioning. The Government of Finland granted to VTT Technical Research Centre of Finland Ltd (VTT) the decommissioning licence in June 2021, and decommissioning is scheduled to commence late 2022. Essential for the FiR 1 decommissioning project, and for fulfilling the prerequisites for the decommissioning licence, is the comprehensive contract on decommissioning services, signed in March 2020 between VTT and Fortum Power and Heat Ltd. The contract covers the dismantling of FiR 1 and all necessary nuclear waste management services as well as the radioactive waste management for OK3 laboratory decommissioning, adjacent to FiR 1. In this paper, we give an overview of the project status, including spent fuel transport for re-use in the US late 2020 (see also [1]) and present examples of progress of characterization work, detailed plans for dismantling and nuclear waste management.
