A special report by the International Energy Agency (IEA), The Role of Critical Minerals in Clean Energy Transitions, released on 5 May, is a comprehensive global study on the central importance of minerals such as copper, lithium, nickel, cobalt and rare earth elements in a secure and rapid transformation of the global energy sector. The 287-page report recommends six key areas of action for policy makers to ensure that critical minerals are available to accelerate the transition to clean energy, rather than becoming a bottleneck.

A mismatch between the world's climate ambitions and the availability of critical minerals could mean a slower and more expensive energy transition, according to a new report from the International Energy Agency (IEA). The Paris-based organisation describes its special report, The Role of Critical Minerals in Clean Energy Transitions, as the most comprehensive global study to date on the importance of minerals such as copper, lithium, nickel, cobalt and rare earth elements in a secure and rapid transformation of the global energy sector.

Russia’s nuclear fuel manufacturer Tvel has completed a second phase of accident-tolerant fuel (ATF) testing by irradiation in the MIR research reactor at the Research Institute of Atomic Reactors (NIIAR) in Dimitrovgrad, southeastern Siberia.

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.

A team at Idaho National Laboratory (INL) in the USA in collaboration with groups at Argonne and Oak Ridge national laboratories, as well as industry consultants and international partners, has for the first time in 30 years had a new material, Alloy 617, accepted into the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code.

Alloy 617 - a combination of nickel, chromium, cobalt and molybdenum - has been approved by the American Society of Mechanical Engineers (ASME) for inclusion in its Boiler and Pressure Vessel Code. This means the alloy, which was developed by Idaho National Laboratory (INL), can be used in proposed molten salt, high-temperature, gas-cooled or sodium reactors. It is the first new material to be added to the Code in 30 years.

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.
