The LVR-15 and LR0 nuclear research reactors are among the pillars of our technology. The LVR-15 reactor is used primarily for irradiation of materials, production of radiopharmaceuticals and experiments using neutron radiography and other applications of neutron beams. The LR-0 reactor is one of the most flexible experimental reactors in the world, in which it is possible to model virtually any configuration of power reactors to verify their neutron-physical characteristics.
