US-based Terrestrial Energy and the Nuclear Research and Consultancy Group (NRG) have started a graphite irradiation testing programme for the Integral Molten Salt Reactor power plant at NRG’s high flux research reactor (HFR) at Petten in the Netherlands.

The work is part of broader programme of testing of components and systems for the IMSR plant, which uses Generation IV reactor technology for electric power generation and heat for industrial heat applications.

The testing programme at the HFR, one of the most powerful multi-purpose research and test reactors in the world, is designed to confirm the predicted performance of selected graphite grades throughout the seven-year cycle of the IMSR core-unit.

The testing will simulate IMSR core conditions, encompassing the full range of IMSR operating temperatures and of the neutron flux. NRG said the HFR has reached full power indicating the successful start of the test programme.

Terrestrial Energy and the US Department of Energy's Argonne National Laboratory (ANL) have begun detailed testing of the fuel salt for Terrestrial's Integral Molten Salt Reactor (IMSR). The IMSR uses two molten salt streams - a fuel salt that contains the uranium and another salt to transfer heat from the reactor to the electricity generation system.

This fuel salt testing programme is part of a broader confirmatory testing programme for fuel, components, and systems used in the IMSR power plant, Terrestrial Energy said.

The results of the tests will support licensing applications for the first commercial deployment of the IMSR power plant. Terrestrial Energy USA is developing the IMSR for US market deployment.

The IMSR is an advanced reactor employing Generation IV molten salt technology. In December 2019 the Canadian Nuclear Safety Commission and the US Nuclear Regulatory Commission chose the IMSR for the first joint technical review of an advanced, non-light-water nuclear reactor technology.

US Department of Energy’s Idaho National Laboratory (INL) said on 24 August that Battelle Energy Alliance (BEA) had initiated contract negotiations with a team led by Bechtel National Inc (BNI) to support the design and build phase of the Versatile Test Reactor (VTR). The BNI team also includes TerraPower and GE Hitachi Nuclear Energy.

Russian state nuclear corporation Rosatom will help Kazakhstan decommission the BN-350 fast neutron reactor at the shutdown Aktau nuclear site on the eastern shores of the Caspian Sea, according to state news agency Ria Novosti.

Ria Novosti said decommissioning of the 350-MW Soviet-era liquid metal fast breeder reactor, also known as Shevchenko and Mangystau, will happen in three stages. The first will involve transferring the reactor installation to safe storage for 10 years. The second and third stages will ensure long-term safe storage for 50 years followed by the dismantling of equipment, buildings and structures, and final management of radioactive waste.

The BN-350 was among the world’s first fast neutron reactors when it began commercial operation in 1973. It was permanently shut down in 1999 and spent fuel removed.

The dismantling of the Ulysse experimental reactor at the French Alternative Energies and Atomic Energy Commission's (CEA's) Saclay site near Paris has been completed. The low-power reactor, which was shut down in 2007, was mainly operated for teaching and continuing education purposes by the National Institute of Nuclear Science and Technology.
