The idea of a reactor was proposed at the Kurchatov. VVER - vodo-vodní energetický reaktor (rusky водо-водяной энергетический реактор), někdy značený WWER (anglicky Water-Water Energetic Reactor) je typ tlakovodního reaktoru užívaného v jaderných elektrárnách v zemích bývalého východního bloku, zatímco v západní Evropě a USA se užívá typ označovaný PWR WWER-440/230 plants, and briefly looks at plans being discussed for its second phase. Design concept review In February 1991, the IAEA conducted a review of the design concept of WWER-440/230 plants. Thirty-two experts from 10 countries and three international organizations participated in the review. Together with 25 specialists from Russia
