Hanhikivi 1 nuclear power plant construction project


May 28, 2022

Hanhikivi 1 is a nuclear power plant ordered by the Finnish energy company Fennovoima, which is to be built on the Hanhikivi peninsula in the municipality of Pyhäjoki. RAOS Project Oy, a subsidiary of the Russian state nuclear energy company Rosatom, was originally chosen as the supplier, but the contract was terminated. The plant's infrastructure has been prepared for the plant, but construction of the plant itself has not begun. Russia invaded Ukraine on February 24, 2022, when Minister of Economic Affairs Mika Lintilä indicated that he was stopping the nuclear power plant project, and Prime Minister Sanna Marin confirmed that the project was not progressing. 2.5.2022 Fennovoima terminated its contract with Rosatom, citing significant delays, Rosatom's inability to supply a nuclear power plant and Russia's invasion of Ukraine.

Plant model

Hanhikivi 1 is a Russian VVER-1200 pressurized water reactor belonging to the VVER plant family. There are two VVER-440 plant units in operation in Loviisa, Finland. The VVER-1200 is developed by Rosatom's subsidiary OKB Gidropress. It has an electrical capacity of 1,200 megawatts, a thermal output of 3,200 megawatts and an efficiency of 37 percent. The type of plant complies with IAEA and European requirements and is designed to meet Finnish safety requirements. In addition to active cooling systems, the plant has passive cooling systems that operate without electricity. The goose turbine and generator are manufactured in France. They are supplied by GE Steam Power Systems and are based on Alstom's Arabelle technology, which was acquired by General Electric in 2015. The plant's automation system is supplied by Framatome in France and Siemens in Germany.

Permission Processes

Founded in 2007, Fennovoima submitted an application for a decision-in-principle to the Government in January 2009, and Parliament granted permission to build a nuclear power plant in July 2010. In January 2012, the company received bids for plant delivery from Areva in France and Westinghouse Electric Company in Japan. However, in October 2012, the German energy company E.ON announced the sale of its 34% stake in Fennovoima, after which Russia's Rosatom became the third plant supplier candidate due to changes in the ownership structure. The plant delivery was initially negotiated with Toshiba and Rosatom, until in July 2013 Fennovoima announced that it would continue to do so between Rosatom. At the same time, the company also announced that it is negotiating the result of Rosatom's subsidiary Rosatom Overseas as a minority shareholder in Fennovoima for one third. Fennovoima and Rosatom signed an agreement for the delivery of the plant in December of the same year. The completed license application was approved later in December, when construction was conditional on at least 60 percent of the nuclear power company's ownership coming from within the European Economic Area. Fennovoima submitted an application for a construction permit for a nuclear power plant to the Ministry of Employment and the Economy on 30 June 2015, after which it must submit an agreement on the final disposal of spent nuclear fuel with the owners of the nuclear waste management company Posiva or an environmental impact assessment. The final disposal issue will also be considered by Parliament later. On 5 December 2014, Parliament approved the decision-in-principle
