NRI: Nuclear Research Institute, Czech Republic

The Nuclear Research Institute Rez plc (NRI) is a public commercial organization in the Czech Republic whose primary mission are R&D in the field of nuclear technology and radioactive waste management. NRI employs about 900 staff, including 450 university graduates. The institute is a non-profit organization in the sense that all profit is reinvested into its own growth and is not distributed as dividends. NRI plays also a role of the R&D base of the Czech Power Company CEZ, which is the main shareholder.

The Nuclear Research Institute Rez plc is a leading organization of the main Czech Partitioning and Transmutation project called SPHINX. The SPHINX project (SPent Hot fuel Incinerator by Neutron fluX) is a Czech national project of Molten Salt Transmutation Reactor technology, which covers R&D of several MSR technologies including theoretical reactor physics, experimental molten-salt irradiation program, development of molten-salt loops, structural materials and primary/secondary circuit technology, pyrochemical processing of MSR actinide fuel and “on-line” reprocessing technologies. The project united the Czech approach to the Partitioning and Transmutation technology with the development of advanced Molten Salt Reactor dedicated to the GEN IV program. The SPHINX project is financially supported mainly by the Czech Ministry of Industry and Trade and by the Radioactive Waste Repository Authority.

Dr. Jan Uhlir, born in 1953 in Prague; MSc, Chemical Engineering, Institute of Chemical Technology Prague (1978); Ph.D., Nuclear Fuel Technology, Institute of Chemical Technology Prague (1989). Began working in NRI in 1978. Head of Fluorine Chemistry Department since 1990. He has been responsible for the chemical partitioning part of the SPHINX project and NRI participation in the PYROREP project of the FP5 and EUROPART and ACTINET projects of the FP6). Fields expertise: inorganic chemistry of fluorine gas and fluorides, pyrochemical reprocessing of spent fuel, chemistry and technology of molten salts.
