MBIR (Multipurpose Fast Neutron Research Reactor)

MBIR is the fourth-generation multipurpose fast neutron research reactor (JSC "SSC NIIAR”), designed for irradiation and post-irradiation research and examination, as well as for the development and testing of cutting-edge technologies and materials. Once the MBIR is commissioned, its predecessor, the BOR-60 (fast experimental reactor), is planned to be shut down.

The unique design, technical and process equipment of the MBIR will enable a wide range of tests and experiments with different options of nuclear plants, within a single reactor, with special circuits running through the core, with the capability to install a separate circuit with its coolant, fuel assembly, and temperature.

Orgenergostroy is the General Contractor of the project and the leader of the construction consortium established to carry out comprehensive works on-site, including the design, construction and installation works, electrical, thermal engineering, ventilation and commissioning works. Insurance and leasing companies, as well as partner banks, joined the consortium, in addition to high-profile specialized construction companies. The relations between all members of the consortium are governed by the relevant agreements and contracts concluded within its framework.

It took Orgenergostroy just 4 months to complete all preparatory stage work since the construction of the MBIR Research Facility was resumed in 2020, including the following:

• The site power supply circuit was restored;
• The mechanization system (tower cranes and concrete placing booms) was restored and improved;
• Temporary roads were arranged;
• A residential camp for staff and a new state-of-the-art construction headquarters were arranged.
• Storage areas for raw materials and supplies were arranged;
• A temporary reinforcement shop was erected and equipped;
• Equipment and materials necessary for the major construction period were delivered to the site;
• Arrangement of concrete batching facilities is heading to completion;
• Concrete mix design charts were elaborated;
• Fire water tanks were erected.

More than 1,200 professionals, including engineering staff, and 80 units of specialized machinery have already been deployed during the main construction period. The construction site is expected to have more than 2,000 people and 100 pieces of construction equipment—at its peak.

In addition, the project applies advanced building information modeling BIM, which is extensively promoted by Orgenergostroy in Russia. Aerial photography and laser scanning from unmanned aerial vehicles are being performed for building the information model. The technology will allow not only a better and more accurate control over the work progress and significantly optimize the cost and timing, but will also minimize the risk of human error and emergencies, both during project implementation and after commissioning of the facility.
