Rosenergoatom Develops Carbon-Carbon Components for High-Temperature Gas-Cooled Reactor
Rosenergoatom, part of Rosatom, has developed full-size carbon-carbon composite components for a high-temperature gas-cooled reactor (HTGR). Research began in 2023 at OKBM Afrikantov in Nizhny Novgorod, leading to the approval of the preliminary HTGR design. Tests at the Institute of Reactor Materials confirmed optimal properties of carbon material for HTGR components. The technology aims to enhance reliability and reduce reactor installation size, focusing on large-scale hydrogen production with a planned NPP featuring four 200 MWt HTGR units.

Rosenergoatom is advancing its high-temperature gas-cooled reactor (HTGR) project by developing full-size components from carbon-carbon composite material. Research initiated in 2023 by OKBM Afrikantov evaluated various carbon materials, leading to the development of an optimal carbon fabric for HTGR components.
Tests conducted at the Institute of Reactor Materials confirmed the material's suitability at temperatures up to 1300 °C. The project aims to enhance reliability and minimize reactor size, with a focus on hydrogen production.
A planned nuclear power plant will feature four 200 MWt HTGR units, utilizing entirely domestic technology. In early 2025, a pilot line will be launched for TRISO fuel pellet production.
