Technological advances associated with the production of radioisotope products in the IVV-2M reactor have been made at the Institute of Reactor Materials. The design of the core and the operating regimes were changed, and the useful neutron load of the reactor was doubled. Novel approaches are presented to the production of high-activity 192Ir in a medium-flux reactor, 14C production by irradiation of aluminum nitride with efficient use of reactor resources and 131Cs by methods giving 99.99% purity, and the possibility of using barium carbonate with native 130Ba content 0.1% as the target material, as well as 177Lu. The most significant achievement is the implementation of a design for creating an intense neutrino source based on 37Ar for the international project SAGE.
