    NPP Angra. Rosatom won the Brazilian Eletronuclear tender for the supply of more than 100 kg of lithium-7 hydroxide for the Angra nuclear power plant. The deliveries will be made by the Novosibirsk Plant of Chemical Concentrates (NССP, Rosatom). Lithium-7 produced by NССP is traditionally used in the nuclear power industry as an additive in the primary coolant of PWR reactors to adjust the water chemistry regime, as well as in the production of chemical reagents for nuclear power. Angra NPP is the only operating nuclear power plant in Brazil, it has two power units with PWR reactors with a total capacity of 1884 MW.
    Environmental protection. Rosatom is completing reclamation of the low-grade uranium ore waste dump at the Taboshar industrial site in Tajikistan. The height of the “uranium” embankment was reduced from 65 to 36 meters, which exceeded the design values. According to the results of monitoring conducted by the Agency for Nuclear and Radiation Safety of Tajikistan, the radiation background at the reclaimed dump decreased 10 times and reached a value of 0.2 μSv/h, which corresponds to the safety norm. “The implementation of the project will ensure the environmental safety of the region without burdening future generations with nuclear safety issues,” said Eduard Nikitin, director of decommissioning programs at Rosatom fuel division.
    Rooppur NPP. A pressure compensator was installed in the reactor building of the Rooppur NPP Unit 2 (Bangladesh). This is a 189-ton vessel designed to create and maintain the required pressure in the primary circuit of the reactor. In addition, it compensates for changes in the volume of the coolant when its temperature fluctuates. Rooppur NPP will consist of two units with VVER-1200 reactors with a total capacity of 2400 MW.

    Rooppur NPP. Work on concreting the outer containment at the Rooppur NPP Unit 1 was completed 45 days ahead of schedule, taking 110 days instead of 155. Earlier, the outer and inner parts of the deflector of the passive heat removal system was mounted in the design position. The operation is particularly complicated since during the installation of these metal structures weighing 140 and 110 tons each, maximum deviations of only up to 10 mm are allowed.
    Akkuyu NPP. Acceptance inspections of fuel components for the Turkish Akkuyu NPP have been successfully completed at Rosatom. The absorbing elements and fuel elements made of uranium dioxide with gadolinium oxide intended for the manufacture of nuclear power plant fuel assemblies, passed the test. “Representatives of the Turkish regulator noted the well-coordinated and professional work of all divisions,” said Ivan Pchelin, Deputy General Director of the Rosatom Machine-Building Plant.
    El-Dabaa NPP. The ship with the first large-sized equipment for the El-Dabaa nuclear power plant sailed to Egypt. The batch includes three main components of the core catcher: body, filler and maintenance platform. The core catcher is a container in the form of a steel cone, which, in the event of an emergency, holds fragments of the core melt and does not allow them to go beyond the hermetic shell of the reactor building. The equipment will arrive at the El Dabaa at the end of March. Earlier, Egypt announced the start of operation of the sea pier at the site of the nuclear power plant.

    Akkuyu NPP. The head of Rosatom, Alexey Likhachev, visited the Akkuyu construction site in Turkey, where he met with the Minister of Energy and Natural Resources, Fatih Dönmez, as well as with representatives of local contractors. Alexey Likhachev expressed his condolences to the families of the victims of the recent earthquakes in Turkey and wished them a fast recovery.  He also spoke about the financing of the project and plans for the construction of a residential campus for the operational personnel of the Akkuyu NPP. The head of Rosatom confirmed that fresh nuclear fuel would be delivered to the site of the station under construction in spring.
    MBIR.  The unique research reactor MBIR, which Rosatom is building in Dimitrovgrad, has become a part of the international platform BRICS-GRAIN (Global Research Advanced Infrastructure Network).  This platform, founded on the initiative of Russia, serves for the access of scientists from the BRICS countries to mega-science projects.  It unites 30 operating and under-construction research facilities, which allow conducting research in the field of nanotechnology, biology, astronomy, energy and fundamental physics.  After commissioning, the MBIR facility will become the most powerful (150 MW) fast research reactor in the world.
    Import Substitution.  The Rosatom fuel division presented AtomReverse, its own digital product for import substitution.  It is intended for a wide range of Russian industrial enterprises from various areas that operate sophisticated imported equipment and have encountered difficulties in updating, repairing and maintaining it. AtomReverse is an evolutionary version of the classic reverse engineering, which is complemented by the capabilities of digital computational modeling, additive technologies and, if necessary, predictive analytics.
