Moscow: More than a thousand new power reactors may come up by 2050 as the world looks at alternate power sources to cut on carbon emission, a top official said on Monday. "Share of nuclear power in the global energy balance will be growing. More than a thousand new nuclear reactors may be constructed and commissioned by 2050. This is a very important task as we need to reduce hydrocarbon consumption globally," Agneta Rising, director general of the World Nuclear Association, said at the opening of nuclear power conference Atomexpo 2016 here. Speaking on the occasion, M.V. Chudakov, deputy director general of International Atomic Energy Agency (IAEA), said nuclear energy is becoming popular as an alternate power source. "Despite events like Chernobyl and Fukushima, more and more developing countries are opting for nuclear power plants," he said. Atomexpo International Forum is an exhibition and business platform on nuclear power industry, which has representatives from 55 countries meeting in Moscow. It will conclude on Wednesday.
