Roof-wetting ceremony for emergency power generator building
19.9.2016
Construction processes continue actively in Olkiluoto. Once again a roof-wetting ceremony was arranged, this time in the emergency power generator building that is taking shape between the two operating plant units. The ceremony took place on Friday, 16 September, when the building was presented to media representatives and invited guests.

- The roof-wetting ceremony, which is held when the building has reached its ridge height, is a significant milestone in this major plant modification project; not that this building actually has any ridge, Virtanen laughs.
All eight emergency power generators for OL1 and OL2 are to be replaced by the year 2022. This is the largest ever modification project at the two operating plants unit in Olkiluoto, and the total budget of the project is more than one hundred million euro. The completely new building that is now about to get its roof wetted is for the ninth emergency power generator that will be acquired in connection with the replacement project. The contractor responsible for the construction project is Skanska Talonrakennus.
The emergency power generator building that protects the equipment related to the ninth emergency power generator system has a floor area of a little more than one thousand square metres and a volume of 4 500 cubic metres. The construction work started in June 2015.

The new ninth emergency power generator can be used to replace any of the eight emergency power generators of OL1 and OL2. The ninth emergency power generator will make it possible to replace a generator even when the plant is in power operation. The extra emergency power generator can later be used when the regular emergency power generators are undergoing maintenance.
The construction project is expected to be completed by the year end. The project has employed an average of 10-20 people on the construction site.
According to plans, the emergency power generator system, including the building, will be ready for operation in April 2018. The connection performance of the system with both of the plant units is to be tested during the 2018 annual outages.
The other eight emergency power generators will be replaced so that all the new systems are in use by 2022. The existing auxiliary buildings for emergency power generators will also be expanded as required during the project.
