VBER-300 The VBER-300 is a Russian pressurized water reactor design intended for medium-sized power generation and desalination, proposed by Rosatom and developed by OKB Gidropress. It has been discussed in technical forums with participation from ASE Group, Atomenergoproekt, and proponents from United Arab Emirates and India among other prospective partners. The concept has been compared in literature to designs by Westinghouse Electric Company, Framatome, and General Electric for small and medium reactors, drawing interest from stakeholders in Brazil, Argentina, Turkey, Egypt, Bangladesh, and Vietnam.

Overview

The reactor concept originated in design bureaus linked to Minatom, with development coordinated by Rosatom and technical input from institutes like Kurchatov Institute and NIKIET. Project presentations have been made at conferences hosted by IAEA, World Nuclear Association, EPRI, and OECD Nuclear Energy Agency. Discussions have referenced comparisons to reactor classes exemplified by VVER-1000, VVER-440, AP1000, and SMART reactor projects. International memoranda have involved delegations from Kazakhstan, Uzbekistan, Belarus, Serbia, Montenegro, and Algeria.

Design and specifications

The VBER-300 employs a pressurized water reactor configuration similar in principle to the VVER family developed by NIKIET and OKB Gidropress. Reported electrical output ranges around 300 MWe with cogeneration capability for steam and water desalination, offering thermal outputs comparable to plants like Hanhikivi, Bushehr, and Kudankulam. The containment and layout have been described in engineering briefings featuring systems analogous to those used at Novovoronezh Nuclear Power Plant, Balakovo Nuclear Power Plant, and Kola Nuclear Power Plant. Auxiliary systems draw on experience from projects executed by Siemens and Alstom in combined heat and power settings.

Reactor technology and safety systems

Designers propose multiple safety trains and passive features influenced by lessons from events at Fukushima Daiichi Nuclear Power Plant, Three Mile Island, and Chernobyl Nuclear Power Plant. Proposed safety systems include redundant emergency core cooling, containment isolation similar to VVER-1200, and instrumentation developed with input from OKB Gidropress and suppliers like Turboatom and Rosenergoatom. Licensing submissions referenced regulatory frameworks used by Rostechnadzor and harmonization efforts with standards from IAEA and Euratom to address severe accident management, station blackout mitigation, and probabilistic safety assessment techniques championed at Sandia National Laboratories and Argonne National Laboratory.

Fuel cycle and waste management

The VBER-300 was proposed to operate on enriched uranium fuel assemblies resembling those used in VVER designs, with possible adaptation for mixed oxide fuel under programs associated with Mayak and TVEL. Fuel fabrication notes drew from facilities such as MAYAK Production Association, Sibmetakhim, and collaborations with firms like Areva NP and Westinghouse. Spent fuel handling strategies referenced dry cask storage practices seen at Kola Nuclear Power Plant and reprocessing routes used at Sellafield and La Hague in international comparisons, while long-term geological disposal concepts cited work at Forsmark, Yucca Mountain Project, and Onkalo.

Deployment, operation, and projects

Pilot deployment discussions have involved potential sites evaluated using environmental assessments guided by Rosatom and local agencies in regions like Kola Peninsula, Primorsky Krai, and prospective export locations such as Egyptian Nuclear Power Plant at El Dabaa and proposals in Bangladesh and Turkey. Operational planning referenced workforce training models from Obninsk Nuclear Power Plant, collaboration with utilities like Inter RAO, and turnkey delivery approaches similar to contracts signed for Akkuyu Nuclear Power Plant and Rooppur Nuclear Power Plant. Industrial partners in negotiations included Siemens, Alstom, Linde, and construction firms such as Stroytransgaz.

Regulatory, licensing, and proliferation considerations

Licensing pathways have been outlined to comply with Rostechnadzor regulations and to pursue international acceptance via IAEA review missions and potential export agreements under frameworks like the Nuclear Suppliers Group guidelines. Proliferation risk assessments referenced safeguards administered by International Atomic Energy Agency and bilateral agreements similar to accords between Russia and Iran or Russia and Egypt. Nuclear liability and insurance arrangements were considered in model contracts drawing on precedents from Convention on Supplementary Compensation for Nuclear Damage discussions and national laws in India, Brazil, and Argentina.

Economic aspects and market applications

Economic analyses compared levelized cost metrics to projects by EDF, Kepco, Rosatom exports, and small modular reactor studies promoted by entities such as NuScale Power and Terrestrial Energy. Market applications emphasized grid support, desalination partnerships like those in Saudi Arabia and United Arab Emirates, and industrial heat supply for petrochemical complexes in regions including Sakhalin and Tatarstan. Financing models referenced export-credit approaches used by Russian Export Center, project financing examples like Eximbank deals, and public–private partnership experiences from Finland and United Kingdom.
