The documents have been signed by Paksi Atomeromu Zrt CEO Gergely Jakli and ASE JSC (part of Russia's Rosatom state nuclear corporation) Vice President Alexander Merten.
"The transition to the direct construction phase gives us the green light to start the production of the main power equipment," said Merten.
According to him, the Paks-2 project is attracting the interest of the Hungarian industry, European countries and other states.
In late 2014, Russia and Hungary signed documents on the construction of new power units No. 5 and No. 6 at the Paks NPP with reactor units based on the advanced Russian VVER-1200 project. Moscow has granted Budapest a state loan of up to ten billion euros, the total cost of the works will amount to 12.5 billion euros. The license for the construction of the new units has already been issued.
