Saudi Arabia’s nuclear program is fundamental to the development of a sustainable energy sector, Saudi Energy Minister Khalid al-Falih told the International Atomic Energy Agency on September 17, according to Arab News.

Saudi Arabia will start building its first two nuclear power reactors this year, with 16 expected to be completed over the next 25 years at a cost of more than $80 billion. The kingdom is aiming to receive 15% of its energy from nuclear sources by 2032.

The program “abides by all international treaties and conventions and best practices, adhering to the highest standards of safety, security and transparency,” Al Falih said.
