work has included several updates of the decommissioning plan of Loviisa NPP.
current plan is based on a detailed activity inventory, work plan and a 3D CAD
model of the plant, as well as a preliminary design of the final disposal plant.
has also conducted a project to evaluate the possibilities
to construct a near surface disposal facility for a very low level of waste to the
Loviisa NPP site. The decommissioning planning has also included studies for
updating the technical design of the repository for decommission waste from the
which is needed for reliable evaluation of the decommissioning costs.
has as well had a role for decommissioning planning of Olkiluoto
site including the following work:
Complete safety case (OL1&2&3);
Ground water flow analysis;
Estimation of radiation dose rates near waste repository and from decommissioning of NPP (OL1&2);
Decommissioning waste inventory for NPP units (OL1&2);
Safety analysis for free released material from Olkiluoto NPP (disposed of to TVO's waste dump on the NPP site);
Updating the work plan and cost estimate of the preparatory phase of decommissioning (OL1&2)
