Rosatom has started the installation phase of the unique MBIR research reactor being built in Dimitrovgrad, Ulyanovsk region. As reported in the press service of the scientific department of the state institution, the installation of technological equipment for transport and technological systems with the first heat removal circuit has begun. This step is key to building the world’s largest fourth-generation multi-purpose fast neutron reactor.
Two large heat exchangers have now been installed, each weighing 38 tonnes, reaching a height of 9 meters and a diameter of 2.5 meters. The installation was carried out with high precision – the deviation from the horizon did not exceed 1 mm per 1 meter. Additionally, barrels for fresh and used assemblies weighing 16 tons each were placed in the design position. These elements will provide the necessary heat exchange effect in the inert gas environment for heating and cooling of fuel assemblies (FA).
Rosatom emphasized that all work at the construction site is progressing according to plan. Installation of equipment at this stage will allow us to concrete the ceiling section of the central hall and continue work at the +11.9 meter level. The ongoing project is an important step for the Russian nuclear industry and promises significant advances in the field of nuclear technology.
