The JSC Nuclear Reactor Research Institute (NIIAR, Dimitrovgrad, Ulianovsk region), who are under Rosatom, have received a license from Rostekhnadzor for the construction of the world’s largest multipurpose fast research neutron nuclear reactor (MFRR) As Construction.ru was told by the institute press service, the license term is 10 years. NIIAR now has the right to start capital works on the construction site of the reactor and preparation for the main construction and installation activities has commenced. Concrete pouring of the MFRR ground slab is to start in the summer. An International Research Centre is to be created alongside this reactor. New types of nuclear materials, construction materials and reactor heat carriers will be studied there. Also, the reactor will produce radioactive nuclides for medical use. Theoretically, fast neutron nuclear reactors render it possible to produce more nuclear fuel than they consume. They are practically safe and friendly for the environment. To remind you, in the summer of 2014 NIIAR got a license for the location of MFRR. As a result of the open tender last November the managing company JSC “Uralenergostroy” became the prime contractor of the construction and started the preliminary period work.
