Research ReactorsResearch reactors LVR-15 and LR-0 are integral parts of the broad research infrastructure of the CV Rez.

The LR-0 research reactorThe LR-0 research reactor of zero power as a unique experimental equipment provides wide spectrum experiments of benchmark and mock-up type for the research in areas of variable reactor cores, reactor pressure vessel and shielding of the energetic reactors.

The LR-0 research reactor The LVR-15 research reactor

The LVR-15 research reactorThe LVR-15 research reactor is a 10 MW multipurpose reactor that provides services in the research areas for the reactor technology and material, industrial materials, radioisotope and radiopharmaceutical development. The LVR-15 is used also as a powerful neutron source of wide energy range for basic and oriented research. A typical operation period a year is of about 200 days.

Technological Experimental CircuitsThe experimental loops allow mechanical, thermal-hydraulic, material, corrosion and further research at the parameters and under operating conditions of investigated reactor concept. By placing loop in the experimental reactor LVR-15, all above-mentioned physical and chemical influences of reactor coolant are supplemented by radiation conditions. These loops can now play an important role in life extending of ongoing types of PWR, BWR and VVER reactors.

• Gen II + III: RVS-3, RVS-4, BWR-1, BWR-2 loops• Gen IV: HTHL, SCWL, PbLi loops

RVS-3 loop serves for an investigation of structural materials mechanical properties, degradation and corrosion behavior under irradiation and PWR/VVER water chemistry and thermal-hydraulic conditions. RVS-4 loop serves for a study of the influence of corrosion product deposition on the surface of fuel elements and the surface of steam generator tubes after circuit decontamination. SCWL serves for a material and chemistry investigation for the SCWR concept. It provides a corrosion testing of candidate materials, a water radiolysis at supercritical conditions, a testing of water chemistry suitable for operation, and a testing of the corrosion of fuel cladding materials –radioactivity transport. HTHL serves mainly for chemistry investigations of the VHTR concept. It provides a He purification system, a study of degradation mechanism of metallic materials under HTR conditions, a tests of nuclear graphite, a creep and fatigue tests of HTR materials. In a fusion research the CVR is interested in two main fields: a Test Blanket Module (TBM) and a Primary First Wall (PFW) testing. The devices serving for this purpose are the BESTH device, the TW-3 probe and the PbLi loop referred to MeLiLoo.

Temelín NPP is currently the only one VVER-type NPP which has the option to repair the fuel assemblies (FA). The repair of FA and also the inspections are carried out during the outage on the Fuel Repair and Inspection Equipment (FRIE) and are primarily performed by the fuel vendor.

The role of the CVR staff is to evaluate and monitor the fuel assemblies condition. These activities include a visual inspection, in which detailed measurements of twist, bow and growth of the fuel assemblies are carried out. The FRIE implementation allows the measurements of oxide thickness on fuel rods to monitor the impact of water regime on the corrosion of fuel cladding and overall fuel assemblies. The results are a feedback to the NPP operator and the fuel vendor for proper operability of the fuel assemblies in order to identify root causes of fuel failures.

Role of the nuclear safety regulation support section is to provide the independent technical and expert support to the state administration in areas of nuclear safety of nuclear power plants, especially for safety analysis report evaluation.

Services, research and development are oriented on state administration support, particularly State Office for Nuclear Safety (SONS), in areas of nuclear safety and energetics. Expert support of SONS is concerned namely about safety analyses for nuclear power plants Dukovany and Temelin.

SUSEN (Sustainable Energy) Project is European project prepared within Priority Axis 2, Operational Programme for Research and Development for Innovations of the European Regional Development Fund (ERDF).

The main aim of the project, which realization is planned within 2012–2015, is to build a complex research centre. The activities of this research centre will be aligned in order to fulfill two key objectives of the SUSEN Project:

Sustainable Energy – SUSEN

• contribution through research and development to providing safe, reliable and long-term sustainable operation of current (Gen II and Gen III) nuclear power plants (prolonging their lifetime by 20 to 40 years);

• contribution to the development of Generation III+ and Generation IV nuclear reactors.

The project submitter is Centrum výzkumu Řež s.r.o. (CV Rez), the project partner is the University of West Bohemia in Plzeň. The SUSEN project is implemented in locality Rez (NRI site) and Plzeň (Technology park Plzeň, Borská pole).

The Jules Horowitz Reactor Collaborative Project (JHR-CP) addresses the support for the implementation of the Jules Horowitz Material Testing Reactor, a new research infrastructure of pan-European interest.

This reactor in the CEA Cadarache research center, will be, for several decades, a high performance major research facility in the European Research Area for nuclear energy and for radioisotopes production.

Several European research institutes and utilities have decided to join the JHR Project for having a long term access to an up-to-date high performance research infrastructure. In the same way, as a contribution to the JHR construction, the JHR-CP gathered well known European research institutes: CEA (France), CIEMAT (Spain), NRI - CV Rez (Czech Republic), SCK-CEN (Belgium), VTT (Finland) etc.

Cooperation on the Academic Field

RCR and Universities

From its very inception our company has closely co-operated with the academic world. The best example of this is the realization of the research project entitled, “Fundamental and Targeted Research in Industry and Medicine on Neutron Sources”, which was conducted between 2004 and 2010 in cooperation with the Institute of Atomic Physics at the Academy of Sciences, Czech Republic (during the project hundreds of combined professional papers and further outcomes were published).

At present within the framework of Education for Competitiveness a project has been approved which deals with the establishment of a centre for the commercialization of the results obtained.

Reseach Centre Řež also closely co-operates with universities – it annually co-arranges professional seminars (4–5 per year), at which leading domestic and foreign lecturers speak, and to which representatives of the universities are regularly invited. We actively co-operate in the realization of technical university student projects.

Excursions to the research reactors take place throughout the year with hundreds of participants from the universities. We work with other organisations (e.g. Institute of Experimental Physics of Czech Technical University in Prague, Faculty of Nuclear Sciences and Physical Engineering of Czech Technical University in Prague, Faculty of Mechanical Engineering of Czech Technical University in Prague) on such projects as MIT, TA CR and further educational programmes from the Structural Fund.

Universities are important partners for RCR. Students have the possibility to connect to the scientific and research activities of RCR and widen their theoretical knowledge gained by study and possibly to verify such knowledge in practice.

The foundation of our co-operation is the conduct of student experience schemes (diplomas, PhDs) and the participation of students in projects carried out at RCR.Graduates have a chance to find employment.
