The article mentions the Saudis want a two reactor plant at 2.8 GW.
That means each reactor is 1.4 GW. Hualong-1 is 1 GW.After a decade of nuclear discussions, the Saudis are pushing to award a contract for the Eastern Province plant, known as Duwaiheen—a two-reactor, 2.8-gigawatt facility—by the end of 2023 and eventually construct 16 reactors at a cost of some $80 billion to $100 billion.
