The project company Kozloduy NPP - New Builds Plc, had issued a call for expressions of interest in participating in the procedure for determining a shortlist of potential construction companies for engineering, construction, delivery and commissioning of a nuclear power plant, by 2 February. It says the candidates expressing an interest were Fluor BV, Bechtel Nuclear Power Company Limited, Hyundai Engineering & Construction, a consortium led by China National Nuclear Corporation Overseas and partner China Energy Engineering Group Tianjin Electric Power Construction Co, as well as China Energy Engineering Corporation Limited.
The initial part of the selection process was to check that those expressing an interest met the qualifying criteria. These include demonstrating construction experience and the commissioning of at least two nuclear units as well as "to have solid experience in the nuclear and turbine island of at least two units or have supplied and installed equipment for two units within the last 15 years - applicants must also demonstrate at least USD6 billion in turnover and profit for the five years period from 2018 to 2022". Candidates from the Russian Federation were specifically excluded.
Kozloduy NPP - New Builds said that, after a commission carried out the pre-qualifying review, "the commission proposed for a shortlist of potential construction companies for engineering, construction, procurement and commissioning of a nuclear power plant at the approved site in Kozloduy with AP1000 technology, on the 'pass/fail' principle: Hyundai Engineering & Construction Co". It added that the commission's report had been accepted and approved by the project company.
Hyundai E&C looks set now to go forward to submit an offer in the next stage of the process.
Bulgaria is aiming to have two new Westinghouse AP1000 units at the Kozloduy nuclear power plant. Deputy Energy Minister Nikolay Nikolov told Bulgaria's official BTA news agency in December that the aim was to achieve a price of about EUR6 billion (USD6.5 billion) for each of the units.
Kozloduy units 1-4 were VVER-440 models which the European Commission had classified as non-upgradeable and Bulgaria agreed to close them during negotiations to join the European Union in 2007. Units 5 and 6 feature VVER-1000 reactors that were connected to the grid in 1987 and 1991, respectively. Both units have been through refurbishment and life extension programmes to enable extension of operation from 30 to 60 years.
When the decision to move ahead with AP1000 units at Kozloduy was given approval by the country's council of ministers in October, the target date for the completion of the first unit was 2033, with the second unit to follow "two or three years after the first one". The 2300 MWe capacity of the two new units would exceed the 1760 MWe capacity of the closed first four units. The Bulgarian government has also said that further units will be needed to replace units 5 and 6 by 2050.
Westinghouse will hold overall Design Authority responsibility for the AP1000 plant, the expression of interest document said, adding: "The responsibilities for the design of individual AP1000 plant systems and buildings shall be delegated by Westinghouse. The responsibility for the design of Modules, Constructions Assemblies and Platforms is aligned with the party that is responsible for the design of the building in which the item is located."
