Posiva is the global leader in final disposal
The world changes. Finland changes. However, the rock beneath us stays put. With a responsible final disposal solution, we enable the production of climate-friendly nuclear electricity. We are the first in the world to begin the safe disposal of spent nuclear fuel into ONKALO® - final disposal facilities excavated deep into the bedrock.
Posiva's final disposal solution is the result of decades of multidisciplinary development. The determined work of Posiva's experts is the foundation of industrial final disposal. We also support sustainable development by exporting our final disposal expertise around the world.
Responsibly from rock to rock. Posiva rocks.
Safe final disposal
Safety is a prerequisite for final disposal. The key to the final disposal of spent fuel is the long-term safety of the solution, which is assessed and demonstrated with a safety case. Safety case refers to all technological and scientific materials, analyses, observations, trials, tests and other proof used to justify the reliability of the assessments made of the long-term safety of final disposal. At Posiva, this means demonstrating the functionality of the geological disposal solution studied and tested for more than four decades in the conditions of the Olkiluoto bedrock, as well as demonstrating the generation of radiation doses to the environment in the event of failure of one or more engineered release barriers and release of radioactive substances from the repository to the living environment.
Posiva solutions - Expertise in final disposal
Posiva Solutions sells and consults know-how generated in spent nuclear fuel design, research and development. The company offers together with an extensive cooperation network tailor-made expert services for final disposal as well as ready-made solutions and service models for nuclear waste management companies.
The Full-Scale In-Situ System Test (FISST) is the most comprehensive full-scale test to date. The Trial Run of Final Disposal consists of a full-scale final disposal test with the final equipment under actual conditions. The only difference to the actual situation is that the canisters do not contain spent fuel.
FISST and YTK
The final disposal solution is driven forward by the experts who have been developing a safe final disposal concept for nearly four decades, the professional project personnel and the partners involved. The multidisciplinary project requires world-class expertise.
Rock to rock
Posiva's owners see the importance of their overall responsibility for all stages of the fuel cycle as important. The safe use of nuclear fuel is ensured from the procurement of raw materials t o final disposal. Fuel is handled responsibly from uranium mines to final disposal in accordance with the Rock to Rock principle.
