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.
