Russia’s Research Institute of Atomic Reactors (NIIAR) in Dimitrovgrad has signed a long-term contract with China’s Fangda Carbon New Material Company.

The agreement covers reactor tests and subsequent post-reactor studies of graphite samples under irradiation conditions similar to those under which graphite should be operated in China’s high-temperature gas-cooled reactor HTR-PM600.

NIIAR specialists will develop and manufacture experimental irradiation devices that will allow irradiation of graphite samples in the cells of the core and the side screen of the BOR-60 research reactor at various temperatures.

The contract also provides for post-reactor studies of graphite samples to achieve different values ​​of the damaging dose.

The experimental data obtained from research will be used by Chinese experts to justify the use of graphite as the structural material of the HTR-PM600 reactor core.

The range of scientific research is expected to be completed in 2024.
