​Preparations for commissioning are in progress in parallel with ongoing installation works in both the reactor island and the turbine island. At present manpower is about 2 400 on the worksite.



Construction work has been completed in the main parts in the reactor island. Finishing works continue on façade outer cladding installation works and roofing. Piping is being installed and construction inspections carried out on component installations. Electrical installation work is under way eg. on fuel transfer and handling equipment. Construction work related to site lighting engineering and emergency power supplies is in progress.

Most of construction work and component installations have been finished in the turbine island. The pre-service tests of electrical and process systems continue. Pressure tests have been carried out in the secondary circuit and commissioning tests of process systems and electrical tests are progressing. The emergency diesel generator in the turbine island has also been tested.

Occupational safety has remained on a good level on the OL3 worksite. The development of accident rate continues to be favourable at less than ten accidents per a million working hours.
