Abstract

The LVR-15 research reactor is operated as a multi-purpose reactor with the utilization tending more towards material research in the reactor’s early years. Later after optimizing of the operation and active core loads, the reactor became also a stable and reliable part in the supply chain of medical radioisotopes, especially ⁹⁹Mo. Nowadays, the radioisotopes production is a well established activity of the LVR-15 facility. Many different types of radioisotopes have been produced. With the increased demand for radioisotopes, especially for nuclear medicine and limited availability of the current reactor fleet, a study was performed to increase the possible 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 the E7 reactor position. The study is performed using experimentally validated calculation models and methods comprising neutron spectra calculation using the MCNP code and further activity determination by the FISPACT-II code. Reasonably achievable activities of the products are determined. Additionally, the self-shielding effect of the target material size was also evaluated.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
