The Research Centre operates two experimental reactors: LVR-15 and LR-0. Both installations together with associated research laboratories make up a large-scale integrated infrastructure, ensuring research and development activity in the field of nuclear research, nuclear energy and those who use irradiation. Both reactors are included in the ESFRI roadmap, and the LVR-15 is among the five largest reactors in Europe included within a framework of international co-operation, in which leading research is conducted with world-class results and whose projects are run under the OP VaVpI program (Operational Programme of Research and Development in Innovation). In addition they allow training of research workers, education of students and co-operation with the industrial sector. For this reason the experimental facilities of these reactors are in systematic use by both domestic and international users. The LVR-15 reactor is a light water tank type research reactor placed in a stainless steel vessel under a shielding cover, with forced cooling, IRT-4M fuel and an operating power level of 10 MWt.
