Nuclear Decommissioning and Waste Management

For more than 30 years, Fortum has been a forerunner in nuclear decommissioning and waste management. We have developed innovative solutions for radioactive liquid purification, waste solidification, interim storage of spent fuel and final disposal of low and intermediate-level radioactive waste. We will be amongst the first nuclear power companies to start the final disposal of spent fuel. See our product offering below and read more of our expertise.

Turn-key solutions for planning and implementation

Nuclear power plant’s decommissioning costs are hundreds of millions per plant unit. Fortum’s approach to decommissioning planning considers nuclear waste disposal and treatment solutions already in the beginning of the NPP operation. This enables optimization of nuclear waste management operations and minimization of the costs of decommissioning a nuclear power plant<
