Fast reactors. The first-ever IAEA OSART mission to the BN-800 fast reactor unit was completed at the Beloyarsk Nuclear Power Plant in Russia. An international team of experts from the UK, France, Iran, Armenia, Belarus, Slovakia and China visited the Beloyarsk site at the request of the Russian government. They spent three weeks reviewing operational safety, reliability and personnel performance at the nuclear power plant. “Following our mission, we are safe to say that Beloyarsk is very close to the ideal vision of the safest power plant because its staff is dedicated, knowledgeable and professional,” OSART team leader Simon Morgan said in conclusion. The Beloyarsk NPP operates two fast neutron reactors, BN-600 and BN-800, which are the world’s most powerful reactors of this type.
