signed an memorandum of understanding regarding the construction, operation and decommissioning of Cernavoda 3 and 4. In February 2020 the prime minister announced that the country would no longer partner with CGN for the project. In October 2020 it was announced that the USA would finance the construction of Cernavoda 3&4, as well as the refurbishment programme of unit 1. In March 2021 Nuclearelectrica said it expects to commission unit 3 by 2031, starting construction in about 2024.The largely-new reactors will be updated versions of the Candu 6, but not the full EC6 version, since the concrete structures are already built. Unit 3 was reported to be 52% completed and 30% for unit 4, though in 2017 the reported figures were 15% and 14%. They would have an operating lifetime of 30 years with the possibility of a 25-year extension. Some 1000 tonnes of heavy water has been produced and is in storage. The partner for Nuclearelectrica in the construction will be from the USA, NuScale Power, rather than China, with a consortium of USA, Canada and France undertaking the construction.
