Centrum výzkumu Řež

What Centrum výzkumu Řež does

Centrum výzkumu Řež (CVŘ) is a Czech public research organisation founded in 2002 as a wholly-owned subsidiary of ÚJV Řež, a.s., focused on research, development and innovation in energy, with nuclear energy as its principal domain. The company operates the LVR-15 and LR-0 research reactors at its Husinec-Řež campus near Prague, supplemented by hot cell complexes, technology loops, microanalysis laboratories, and an extensive suite of specialised facilities including HELCZA (world-unique for ITER fusion first-wall testing), S-Allegro (high-temperature gas-cooled reactor component testing), sCO2 Energy cycles, Hot Isostatic Pressing, and Molten Salt Oxidation/Experimental Technology Line for radioactive waste processing. CVŘ also holds a patent on the Energy Well small modular reactor concept (molten-salt) and has developed the CR-100 reference SMR design.

CVŘ generates revenue through a hybrid model combining institutional and grant funding from the Czech Ministry of Industry and Trade (MPO), TAČR (THÉTA, NCK, OP PIK) and EURATOM R&I programmes (approximately 20 active projects with CVŘ coordinating 2), project-based R&D contracts with nuclear utilities (ČEZ, Dukovany and Temelín), OEMs and international partners (Hitachi, Mitsubishi Heavy Industries, Kajima Corporation, Mitsubishi Research Institute), state regulatory authorities (SÚRO, SÚJB), and commercial radiopharmaceutical production (notably molybdenum-99) via the LVR-15 reactor. The CICRR Open Access programme provides structured access to research infrastructure for domestic and international research institutions, universities, and industrial partners. Following its April 2026 merger with Výzkumný a zkušební ústav Plzeň (VZÚ Plzeň), CVŘ operates from two campuses — Husinec-Řež and Plzeň — and has expanded into hydrogen technologies (H2PPM 2026), thermal energy storage (TES), and advanced manufacturing services, while spinning off commercial activities to a wholly-owned subsidiary iCVŘ.

Broad incumbents

• Framatome: One of the world's leading suppliers of nuclear reactor technologies, fuel, and services, with overlapping capabilities in fuel design, reactor core modelling, and safety analysis — both a strategic partner of CVŘ (May 2026 partnership) and a much broader incumbent in the same value chain.
• TÜV SÜD: Global testing, inspection, and certification company with nuclear safety assessment, supplier qualification, and component certification services — comparable in service categories (especially under EUAKAEAH supplier qualification and EUAKAAAI QA/QC) though operating as a broad multi-industry incumbent rather than a nuclear-only specialist.

Others

• ÚJV Řež, a. s. Parent company of CVŘ and part of the ÚJV Group; provides nuclear engineering, safety, and consulting services across the Czech nuclear fleet — directly related as parent and ecosystem participant rather than direct competitor in research infrastructure.
