Researchers at Russia’s NRNU MEPhI (National Research University - Moscow Power Engineering Institute) are investigating the accumulation of helium and deuterium in promising "smart" W-Cr-Y alloys for use in thermonuclear reactors. The results of the study were published in the Journal of Nuclear Materials. The interaction of plasma with the inner wall of a fusion reactor are a major obstacle to achieving fusion energy, explained Zori Arutyunyan, Candidate of Physical & Mathematical Sciences, and Junior Researcher at MEPhI’s Department of Plasma Physics.

Rosatom fuel company TVEL and the Troitsk Institute of Innovative & Thermonuclear Research (TRINITI) have developed a technology to decontaminate radiation-contaminated metal equipment using ozone baths. TVEL says it is much more efficient than foreign counterparts, and makes it possible to significantly reduce time needed to treat secondary liquid radwaste.

The AA Bochvar Research Institute of Inorganic Materials (VNIINM), a subsidiary of Russian nuclear fuel manufacturer TVEL, has successfully developed the technology and manufactured experimental fuel pellets from uranium disilicide for light water reactors. The move is part of a programme for the development of so-called accident-tolerant fuel (ATF).

Each of the three combined TVS-2M fuel assemblies, designed for Russia’s VVER-1000 power reactors, contains 12 experimental fuel rods. Six of them have their cladding made of chromium-nickel alloy, and the other six have a standard zirconium alloy cladding with chromium coating.
The fuel was loaded into the 950-MW plant during a scheduled maintenance and refuelling and the plant has now returned to service.

Advanced fuel assemblies have begun an operational trial at Russia's Rostov nuclear power plant. Fuel manufacturer TVEL said if successful they would provide a higher level of performance and safety. "Fuel irradiation in a commercial reactor is an important step for the further commercialisation of this product," said Natalia Nikipelova, president of TVEL, adding: "It is symbolic that this milestone is achieved when TVEL celebrates its 25th anniversary."

OECD experts foresee that accident tolerant fuels (ATF) will dominate the nuclear fuel market within 10 to 20 years. This is a very short timeframe by the standards of the nuclear industry, where reactor research and preparation alone can take up to a decade, writes Natalia Nikipelova, president of Russian nuclear fuel manufacturer TVEL. Such an optimistic forecast means that ATF is a product very much anticipated by the market. After all, ensuring nuclear safety - that there will be no serious consequences even in the event of incidents as grave as Fukushima - is a crucial step towards increasing public acceptance of nuclear energy. And, as we all know, where there is demand, supply will follow.

The first experimental ATF fuel assemblies were loaded into the reactor in January 2019 and a first round of testing was completed in October the same year.
Tvel said each fuel assembly contains 24 fuel elements with four different combinations of cladding and fuel matrix materials, while fuel pellets were made of traditional uranium dioxide, and uranium-molybdenum alloy with increased density and thermal conductivity.
Zirconium alloy with a chromium coating and chromium-nickel alloy were used as rod cladding material, the state-owned company said.

The Research Institute of Atomic Reactors (NIIAR) in Dimitrovgrad, in the Ulyanovsk region of Russia, has completed the second cycle of irradiation of the experimental fuel assemblies with VVER and pressurised water reactor fuel rods in the MIR research reactor. This marks the latest milestone in the development of Russian accident tolerant fuel, state nuclear corporation Rosatom announced today.

The first Russian-made nuclear fuel assemblies with experimental accident-tolerant fuel (ATF) rods for commercial reactors have been manufactured and passed acceptance inspection at Novosibirsk Chemical Concentrates Plant, a fabrication facility of Rosatom’s fuel manufacturer subsidiary TVEL. The ATF rods are to be loaded into one of the VVER-1000 units at the Rostov nuclear power plant in western Russia in the first quarter of 2020, TVEL said yesterday.
