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).

Lightbridge Multi-Zone Fuel Element Granted Japanese Patent, Covering Fuel Assemblies and 3D Printing Manufacturing Methods

Advanced nuclear fuel technology company Lightbridge Corporation recently announced that its Japanese patent application for a multi-zone fuel element has been granted by the Japan Patent Office. The patent covers the fuel element design, fuel assemblies incorporating the design, and methods of producing the element via additive manufacturing, i.e., 3D printing. According to the disclosure, the patent involves a fuel rod composed of three layers of different materials. The thickness of the three layers can vary along the length of the fuel rod, thereby regulating fuel performance at different positions in the reactor to enhance reactor operating performance and safety margins. In addition to the fuel rod itself, the patent also covers fuel assemblies for mounting these fuel rods.

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...

Russian Researchers Develop High-Wear-Resistant Steel Sample for Nuclear Waste Processing

Novosibirsk State Technical University (NSTU) recently announced that Russian researchers have developed a steel sample with reinforcing elements. Experimental results show that the durability of this material is approximately 4 times that of 5KhNM tool steel currently used in nuclear power plant waste processing equipment. The research focuses on improving precipitation hardening steel structures. Precipitation hardening steel is a special class of alloy material that, after quenching and holding at specific temperatures, precipitates fine, hard particles within the steel, thereby enhancing strength and wear resistance. The researchers aim to replace existing 5KhNM tool steel with new high-strength alloys...
