Preparations underway for decommissioning of Kursk 1&2
08 May, 2024
Specialists from ODITs-RBMK and Kursk NPP continue to prepare for the decommissioning units 1&2 at Russia’s Kursk NPP. The NPP comprises four ageing RBMK-1000 units, two of which are now closed down. The station's units were connected to the grid in 1976, 1979, 1983 and 1985. In 1994-2009, all units underwent thorough technical modernisation. Unit 1 was closed in 2021 and unit 2 in January 2024.

Tomsk Polytechnic develops new method to obtain ceramic composites for nuclear energy
08 May, 2024
A new way to synthesise high-strength composites based on MAX phases for the aerospace industry and nuclear energy has been developed by scientists from the Engineering School of Nuclear Technologies at the Tomsk Polytechnic University (TPU). MAX phases are a large family of materials with more than 150 different compositions that have been extensively investigated during the last 25 years. They present a layered structure and a unique combination of properties, bridging the gap between metallic and ceramic properties. However, despite their excellent oxidation resistance up to 1400°C under corrosive environment, good damage and radiation tolerance, thermal shock resistance, and self-crack healing, their application has been limited by three main factors: the complexity of this large family of materials; unavailability of highly pure commercial powders; and the extensive time needed to license products in strategic fields such as nuclear or aviation.

UKAEA signs agreement with CVŘ to test STEP components
08 May, 2024
The UK Atomic Energy Authority (UKAEA) and Czech Republic research organisation Centrum výzkumu Řež (CVŘ), have signed a multi-year use of facility agreement. This will enable unique testing of High Temperature Superconducting (HTS) tapes, critical for the development of the UK’s prototype fusion energy powerplant, the Spherical Tokamak for Energy Production (STEP). These tapes are intended to confine STEP’s fusion plasma, a superheated gas of hydrogen isotopes, in a tokamak. Under intense heat – 150m degrees celsius, ten times hotter than the core of the sun – and pressure, the isotopes fuse into helium, releasing energy as neutrons.

South Bruce signs hosting agreement with NWMO
08 May, 2024
Canada’s Municipality of South Bruce Council has endorsed the Hosting Agreement between the Municipality and the Nuclear Waste Management Organisation (NWMO). Mayor Mark Goetz and CAO Leanne Martin signed the agreement on behalf of the Municipality following a vote in the Council. The area is one of two potential host sites for a deep geologic repository selected in a process launched by the NWMO in 2010. The Township of Ignace signed a hosting agreement with the NWMO in March.

08 May, 2024
Painting of the inside of the cooling tower at unit 1 of Russia’s Kursk-II NPP, which began in September 2023 and has now been completed. Inside, the coating serves as additional protection for hydrophobic concrete from excessive moisture and has a uniform light colour.

Kazatomprom releases quarterly update
08 May, 2024
Kazakhstan’s national atomic company Kazatomprom has reported a slight year-on-year increase in its first quarter uranium production. Production for the quarter was 5077 tU (100% basis), up from 4744 tU for the same period in 2023, a year-on-year increase of 7%. However, Kazatomprom emphasised that its production guidance for 2024 of 21,000-22,500 tU (100% basis) remains unchanged while noting that "sanctions pressure due to the Russian-Ukrainian conflict and limited access to some key materials are not known". As a result, “annual production volumes may differ from internal expectations".

Doosan Enerbility to supply feeder pipes for Cernavoda NPP
07 May, 2024
South Korea’s Doosan Enerbility has signed a contract with Canada’s Candu Energy to produce and supply feeder pipes for unit 1 of Romania’s Cernavoda NPP. This is the fifth order for feeder pipes, following those for NPPs in China and Canada. Feeder pipes are an important part of a pressurised heavy water reactor (PHWR). They are pipes through which coolant flows to control reactor temperature. Under this contract, Doosan Enerbility will supply a total of 1,520 feeder pipes to Candu Energy by 2027.
