Rosatom has developed the first batch of nuclear fuel assemblies for the MBIR multi-purpose fast reactor, successfully passing factory acceptance testing

At the site of the Fuel Technology Division of the State Scientific Center — Research Institute of Atomic Reactors (NIIAR, Dimitrovgrad), under the Scientific Division of Rosatom, the first batch of 3 pilot nuclear fuel assemblies (Fuel assemblies / ТВС) for the multi-purpose sodium-cooled fast neutron research reactor (MBIR) successfully completed comprehensive factory acceptance tests. The professional acceptance committee conducted a thorough review of the maturity and completeness of the fuel production process line for this batch as well as all technical performance parameters of the trial-manufactured assemblies, and completed high-precision geometric dimension and quality re-verification measurements item by item. This acceptance review brought together the expertise of multiple core research and manufacturing institutions in the Russian nuclear industry, including the Dollezhal Research and Development Institute of Power Engineering (NIKIET), the Institute of Physics and Power Engineering (IPPE), and the Machine-Building Plant Joint Stock Company (MSZ, Elemash).

Initial Testing Completed for Nine Fuel Handling Gripping Devices for MBIR Project

On August 17, 2026, Russia's InterPolaris completed initial testing of nine gripping devices for the Multipurpose Fast Neutron Research Reactor (MBIR) project. These devices will be used for fuel transport and handling operations, primarily serving the handling and transfer of fuel assemblies and fuel rod storage within the OTT fuel complex. The key focus of the device development is to enhance safety and reliability during the gripping, transfer, and positioning of fuel assemblies. Each gripping device consists of components including an eyelet, body, cover plate, head, cam, locking sleeve, indicator light, battery, stepper motor with electrical connections, and a backup device. Among these, the locking sleeve is used to prevent accidental cam opening, and the backup device...
