Institute for Safety Problems of Nuclear Power Plants (NASU) The Institute for Safety Problems of Nuclear Power Plants (NASU) is a research institute within the National Academy of Sciences of Ukraine focusing on safety analysis, risk assessment, and mitigation technologies for nuclear power plants. The institute conducts theoretical and experimental research informing regulators, industry operators, and international organizations, and engages in post-accident analysis, design review, and training programs. Its activities intersect with agencies, laboratories, and academic institutions across Europe, North America, and Asia.

History

The institute was established under the auspices of the National Academy of Sciences of Ukraine during the late Soviet period, developing amid responses to the Chernobyl disaster and the evolving regulatory environment shaped by International Atomic Energy Agency dialogue. Early collaborations involved institutions such as the Kurchatov Institute, State Scientific Center of the Russian Federation – Institute for Nuclear Research, and the Argonne National Laboratory, and were influenced by policy developments like the Convention on Nuclear Safety and the Joint Convention on the Safety of Spent Fuel Management. During the 1990s the institute expanded links with the European Commission, United States Department of Energy, and the World Bank for post-accident remediation, interacting with programs from the European Bank for Reconstruction and Development and the International Atomic Energy Agency missions. Throughout the 2000s and 2010s it participated in multinational projects involving the European Atomic Energy Community, the Organisation for Economic Co-operation and Development, and the International Science and Technology Center.

Mission and Research Focus

The institute’s mission aligns with mandates from the National Academy of Sciences of Ukraine and reflects priorities set by the International Atomic Energy Agency and directives influenced by the European Commission energy policy. Research focuses include severe accident phenomenology, probabilistic safety assessment applied to reactor designs such as the VVER-1000, RBMK and small modular reactors developed in programs like those by Westinghouse Electric Company and NuScale Power. The institute addresses containment behavior studied by teams from Oak Ridge National Laboratory, Sandia National Laboratories, and Paul Scherrer Institute, while developing instrumentation compatible with standards from International Electrotechnical Commission and International Organization for Standardization. Work also supports emergency preparedness protocols similar to those promoted by United Nations Office for the Coordination of Humanitarian Affairs and World Health Organization frameworks.

Organizational Structure

The institute is organized into departments and laboratories reporting to a director appointed under the National Academy of Sciences of Ukraine. Departments mirror themes found at establishments like Lawrence Livermore National Laboratory, Cadarache, and Helmholtz Association. Core divisions include reactor safety analysis, thermal-hydraulics, materials degradation, human factors, and probabilistic risk assessment, interacting with centers of excellence such as Imperial College London, Massachusetts Institute of Technology, University of Cambridge, and Moscow State University. Administrative and legal functions liaise with entities like the State Nuclear Regulatory Inspectorate of Ukraine, Ministry of Energy and Coal Mining of Ukraine, and international bodies including the Nuclear Energy Agency.

Major Projects and Contributions

The institute has contributed to safety assessments for Zaporizhzhia Nuclear Power Plant, Rivne Nuclear Power Plant, South Ukraine Nuclear Power Plant, and projects associated with Chernobyl Nuclear Power Plant remediation. It led work on probabilistic safety assessments comparable to programs at Electric Power Research Institute and developed models in collaboration with European Organization for Nuclear Research expertise. Contributions include analysis used in licensing reviews resembling procedures at the United States Nuclear Regulatory Commission and technical input to reactor modernization efforts influenced by Rosatom and Framatome. The institute participated in international research consortia with International Science and Technology Center, Center for Energy and Environmental Studies, and universities such as University of Manchester and Technical University of Munich.

Collaborations and Partnerships

The institute maintains partnerships with the International Atomic Energy Agency, European Commission, United States Department of Energy, United Kingdom Atomic Energy Authority, and research centers like Oak Ridge National Laboratory and Paul Scherrer Institute. Academic collaborations extend to Kyiv Polytechnic Institute, Taras Shevchenko National University of Kyiv, Sevastopol National Technical University, and foreign universities such as Delft University of Technology, Politecnico di Milano, and École Polytechnique Fédérale de Lausanne. It engages in projects with industry stakeholders including Westinghouse Electric Company, Framatome, Rosatom, Siemens, and General Electric and works with regulatory and funding bodies like the European Bank for Reconstruction and Development and World Bank.

Facilities and Laboratories

Experimental facilities include thermal-hydraulics loops, materials testing rigs, containment test stands, and control room simulators comparable to those at Paul Scherrer Institute and INR Pitesti. Laboratories support metallurgy studies using equipment paralleling resources at Fraunhofer Society and neutron irradiation capabilities linked with regional reactors like Kharkiv Institute of Physics and Technology facilities. Computational clusters enable modelling with codes developed in partnership with CERN collaborators and adapted from platforms used by Argonne National Laboratory, Lawrence Berkeley National Laboratory, and Idaho National Laboratory.

Impact on Nuclear Safety Policy

Research outputs inform policy instruments administered by the State Nuclear Regulatory Inspectorate of Ukraine, feed into international reviews by the International Atomic Energy Agency and influence European nuclear safety practices aligned with European Atomic Energy Community standards. The institute’s assessments have been cited in safety upgrading programs funded by the European Bank for Reconstruction and Development and have contributed technical evidence to bilateral dialogues with agencies such as the United States Department of Energy and Ministry of Energy and Coal Mining of Ukraine.

Awards and Recognition

The institute and its staff have received recognition from national bodies including awards from the National Academy of Sciences of Ukraine and honors in collaborative projects acknowledged by the International Atomic Energy Agency, European Commission, and multinational consortia alongside partners like Oak Ridge National Laboratory and Lawrence Livermore National Laboratory.
