Posiva's Annual Report 2018 is published
Finland has progressed the furthest in the world in the preparation of final disposal of spent nuclear fuel and this is something we take pride in at Posiva. In 2018, Posiva carried out an assessment of its capabilities for the construction of the encapsulation plant and started the final technical preparation of the underground final disposal repository.
During 2018, work progressed both at the final disposal facility and on the drawing board. Excavations for access connections for vehicles, technical facilities, and a central tunnel for the joint functional test were completed. Production processes, subcontractor chains and cost estimates were finalised in more detail and decisions on the implementation of industrialisation activities were made based on them. The purpose of industrialisation is to simplify processes and improve the manufacturability of components, among others. Good progress was made last year in the preparation of the construction of the encapsulation plant.
One of the most important accomplishments in 2018 was the start of the Full Scale In Situ System Test (FISST) in ONKALO® in the summer. The follow-up of this full-scale final disposal test will continue for several years and it is designed to demonstrate that Posiva’s concept for safe final disposal can be implemented according to plans.Posiva's Annual Report
