[en] Research Centre Rez (RCR) is a research organization focused on research, development and innovation in the energy sector, primarily nuclear energy, reactors physics, chemistry and materials. RCR currently operates ten radiation workplaces of the II, III and IV category. From the point of view of the way in which ionizing radiation sources are handled these workplaces are rather different. Therefore a differential approach is required to ensure the radiation protection requirements. The radiation protection in RCR is organized into three separate infrastructures, each with an own radiation protection officer. The 'SUSEN' infrastructure includes eight workplaces of the II and III category in which are handled unsealed and sealed radionuclide sources of simple and significant sources category and a particle accelerator of a model 14 MeV D-T neutron generator. Five of radiation workplaces of this infrastructure were newly established within the SUStainable ENergy Project (SUSEN) in the end of 2016, especially for the material research purpose. Two other workplaces are planned to be established this year. The 'REACTORS' infrastructure includes two workplaces of the IV category with LVR-15 and LR-0 research reactors. Both reactors were operated by UJV Rez company until 2012. The 'PFW PILSEN' infrastructure includes a newly built workplace of the II category with a 0.8 MW radiation generator, established in 2018. The common problem of radiation protection related to the operation of these RCR workplaces is the modernization of documentation for approved activities under the new Atomic Act and the provision of uniform approaches in the field of radiation protection, training of workers and safe management of radiation sources.

[en] The article commemorates the 50th anniversary of the Faculty of Nuclear Sciences and Physical Engineering, Czech Technical University in Prague, paying particular attention to the department (whose current name is the Department of Nuclear Reactors) that has been educating and training specialists in the theory and technology of nuclear reactors / nuclear power engineering. Both the educational and scientific research activities of the department during the past 15 years are described. The department's fundamental responsibilities include, among other things, the operation and use of the VR-1 training reactor. The prospect of the department in the near future are also outlined.

[en] It describes how learning by students and professional staff of nuclear facilities in the Czech Republic and Slovak Republic in the field of radiation protection within the reactor experiments at the school VR-1 Sparrow (CTU Faculty of Nuclear Sciences), where radiation protection is a natural essential part of every teaching and activities at the reactor. Reactor is presented and learning module 'Radiation Protection and Dosimetry' created for IAEA training courses - EERRI Group Fellowship Training Programme on Research Reactors (2010, 2011), which are intended for future training of personnel research reactors in IAEA Member States interested in the development of nuclear energy, but with little experience in this area.

[en] The neutron flux density distribution and the neutron energy spectrum at the end of the pneumatic post tube in the C1 core of the VR-1 training reactor were determined. Irradiation of activation foils and wires was used. The neutron energy spectrum was deconvoluted by means of the SAND-II code. The results were compared with appropriate MCNP calculations
