Abstract The LVR-15 research reactor is operated as a multi-purpose reactor focused primarily on material research. Production of radioisotopes is a well-established activity of the LVR-15 facility, as well since the reactor also represents a stable and reliable producer in the supply chain of medical radioisotopes, especially 99Mo. Different types of radioisotopes have been produced over the years. With the increased demand for radioisotopes, especially for nuclear medicine and limited availability of the current reactor fleet, a study was performed to analyze a possible increase and optimization of production capabilities of the LVR-15. The present production possibilities are discussed in the following paper with their possible expansion involving an irradiation channel mounted in another position of the reactor core marked E7. The study is performed using validated calculation models and methods comprising neutron spectra calculation using the MCNP code and further activity determination by the FISPACT-II code focusing on an irradiation of samples in a drilled cask. Additionally, heavy water and graphite were considered as a moderator inside the cask for some of the samples. Reasonably achievable activities of the products are determined. Self-shielding effect of the target material size was also discussed.
