The talk describes the investigations on high-Ni, high-Mn and low-Cu weld metals from the decommissioned Barsebäck 2 boiling water reactor (BWR) reactor pressure vessel (RPV). The reactor pressure vessel head (RPVH) weld and axial and circumferential beltline welds of the Barsebäck 2 RPV have been studied. The investigations includ...

The CoE NOMATEN team (NCBJ + VTT) on March 13-15, 2024 visited companies in the Gdańsk Pomerania region that implement numerous energy projects, including nuclear energy, solutions in the field of renewable energy sources and a sustainable energy system in the country and in Europe. Another on-site visit of CoE NOMATEN directly to production plants was aimed at presenting the research and design capabilities of the NOMATEN Center and encouraging companies to implement joint research and implementation projects in the field of energy solutions and material technologies.

Microstructural stability of multi-component systems under extreme environment represents one of most challenging issues not only in multi-scale materials modelling but also for developing reliable and advanced engineering components for nuclear material applications. Recently, compositionally complex alloys (CCAs) are designed as novel radiation-resistant materials for future fusion power plants while...

The development of chemical reactions that can be performed in living systems (i.e. cells, model organisms) has long held unique fascination in the field of chemical biology. A bio-orthogonal reaction is characterized by the reaction of two functionalities, which will react under mild physiological conditions and are inert towards the biological environment.

CoE NOMATEN continues to implement scientific workshops in the field of advanced materials. This time, together with Łukasiewicz – Institute of Aviation, we will implement a workshop and meeting on research of materials used in the energy industry and aerospace sector at which we will discuss joint research, technological and infrastructural opportunities in this area. One of the goals of the meeting will also be to discuss joint R&D activities and projects for the development of the energy sector in Poland. CoE NOMATEN and NCBJ will present their research infrastructure, which will be used in cooperation between our Institutes.

Body-centered-cubic (BCC) high entropy alloys show exceptional strengths up to 1900K [1]. Fundamental understanding of the mechanisms that control strengthening is necessary to formulate a theory that enables screening over the immense compositional HEA space [2]. Supported by experimental findings in NbTaTiV and CrMoNbV alloys [3], we show with theory [4] that edge dislocations can

Faced with major societal challenges (ecological crisis, energy crisis), it is essential to better understand the behaviour of materials in order to improve the lifespan of nuclear reactors as well as their safety. The properties of materials are... 

CoE NOMATEN 2024 started with a workshop with industrial companies, where the Centre's competencies and research capabilities were discussed and the research infrastructure at NOMATEN was presented. One of the objectives of the meeting was also to discuss the possibility of cooperation with companies in the modernisation of the MARIA research reactor at the NCBJ and conducting joint research and projects for the development of the energy sector in Poland.

Hydrodynamics can play a critical role in the degradation of materials, often defining the rates and mechanisms by which metals corrode. To improve the understanding of the relationship between fluid flow and corrosion, precise and well characterised experimental techniques are required. The application...

Atom probe tomography (APT) is a unique analysis technique providing chemical analysis with near atomic resolution in 3D. Here, recent APT research on nuclear materials performed at Chalmers University will be presented. Zirconium alloys are used as fuel claddings in nuclear reactors and undergo degradation due to corrosion, hydrogen pick-up and irradiation damage. Using APT...
