The LVR-15 reactor is a multipurpose research facility used for basic research on horizontal channels, material and corrosion studies in loops and irradiation rigs, and for the isotope production. A conversion from HEU (IRT-2M 36%, so far used) to LEU (IRT-3M 19.5%, IRT- 4M 19.5%) is planned till 2010. The influence of the new type of fuel on the performance of the experimental facilities operated at the reactor has been studied. The comparison of the calculated neutron fluence rates and spectra using NODER operational code (3D nodal diffusion) and MCNP code for both the fresh and depleted cores was performed. Results of the analyses and future plans are presented in the article.
