Teollisuuden Voima Oyj’s Interim Report January – June 2019
18.7.2019
During the first half of 2019, Teollisuuden Voima’s (TVO) electricity generation at Olkiluoto 1 and Olkiluoto 2 plant units continued safely and reliably. The electricity production of Olkiluoto nuclear power plant reached 500 TWh on 21 April.
The preparations for the loading of nuclear fuel continued at Olkiluoto 3 EPR. The liquid absorber solution for the vibration of the pressurizer surge line was approved by Radiation and Nuclear Safety Authority in May. After the interim report period TVO received an updated schedule for the commissioning of the OL3 EPR plant unit from the plant supplier Areva-Siemens Consortium. According to the received information, the regular electricity generation at the OL3 plant unit will start in July 2020.
Posiva has decided to implement the production facility which is designed for spent fuel handling and consists of the encapsulation plant and the final disposal facility. In addition to construction of the encapsulation plant the rooms that have already been excavated in ONKALO shall be equipped with the systems needed for starting the final disposal.
Assessment of Year-End Developments
Electricity production is expected to continue as in previous years. The prerequisites for nuclear power production at Olkiluoto are good. Nuclear fuel availability is guaranteed by long-term agreements.
Realization of the OL3 EPR nuclear power plant project and preparing the plant unit for production will be continued. For the loading of nuclear fuel, TVO still needs a separate permission from the Radiation and Nuclear Safety Authority (STUK). Suppression of pressurizer surge line’s vibration detected in hot functional testing (HFT) is in progress and will be completed before fuel loading. TVO will continue to support the Supplier to complete the project.
Meri-Pori coal-fired power plant’s capacity is used according to Fortum’s operation plan.
The construction of Posiva’s production facility for handling of spent nuclear fuel will be continued.
