Bay Zoltán Nonprofit Ltd. for Applied Research participates in the project Fracture mechanics testing of irradiated RPV steels by means of sub-sized specimens (FRACTESUS).

By 2050, the EU aims to have more than 80 % of its energy coming from renewable sources, with electricity providing for half of the final energy demand. To achieve this ambitious goal, the energy mix will include nuclear power – existing nuclear power plants and future nuclear systems. The EU-funded FRACTESUS project will address the safety and operability of nuclear systems. Since this relies on the integrity of structural material, the project will work to establish the foundation of small specimen fracture toughness validation and demonstration. The project’s goal is to join European and international efforts to achieve a change in code and standards and address the various national regulatory authority concerns.
