[1] In 1977 the Romanian Government signed a contract with AECL to build a five unit nuclear power plant in Cernavodă using Canadian CANDU reactor technology.
Unit Two took 27 years to build, achieving initial criticality in 2007[4] and produces 706 MW of electricity.
On 7 March 2008, Nuclearelectrica, ArcelorMittal, CEZ, Electrabel, Enel, Iberdrola and RWE agreed to set up a company dedicated to the completion, commissioning and operation of Units 3 and 4.
The cost estimate put completion of both reactors at EUR 2.5 billion, with seven companies investing into the project, including the state run Societatea Nationala Nuclearelectrica.

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.
