Η επιστήμη των υλικών είναι ένας από τους κύριους μοχλούς της τεχνολογικής ανάπτυξης και της βιομηχανικής καινοτομίας. Στον πυρηνικό τομέα, η έρευνα υλικών διαδραματίζει κρίσιμο ρόλο στη βελτίωση της ασφάλειας, της αποδοτικότητας και της οικονομίας των πυρηνικών εγκαταστάσεων. Υποστηρίζει τεχνολογικές βελτιώσεις και βελτιώσεις ασφαλείας σε υφιστάμενους πυρηνικούς αντιδραστήρες και σε νέες κατασκευές. Επίσης, επιτρέπει την ανάπτυξη προηγμένων σχεδίων αντιδραστήρων (συμπεριλαμβανομένων των SMR).

Radiological and nuclear technologies are integral to modern healthcare. They play a crucial role in cancer care – from early detection and diagnosis to treatment and palliative support.

They also support the diagnosis and management of a wide range of other conditions (including cardiovascular and neurological diseases). Each year, patients throughout the EU benefit from the application of nuclear medicine in the diagnosis and treatment of cancer and other serious conditions.

Safety of SMRs, advanced and innovative nuclear reactors and fuels

Opened

Code: 40210 | Identifier Code: HORIZON-EURATOM-2026-01-02 | Programme name: 23715 | Start submission calls: 23/04/2026 | End submission calls: 15/09/2026

the Commission expects from this Topic a balanced portfolio of projects covering both LW-SMRs and AMRs with their fuel cycles. The focus on safety will also cover research and innovation needed to independently demonstrate the safety of innovative systems, critical structures for both LW-SMRs and AMRs with their fuel cycles.

Developers’ goals are systems that offer increased safety, sustainability, economic competitiveness, and also enhance fuel efficiency, minimise waste generation, foresee non-electric applications and flexibility in terms of adaptation to the energy mix with intermittent/variable sources. These innovative reactor technologies aim at including safety-by-design features. Research should also be conducted on the safety of advanced coolant technologies, reactor hybridisation and fuel designs.

This call topic contributes to the STEP objectives, as defined in the STEP Regulation.

Proposals must address disruptive knowledge, products and technologies in any area of defence interest6 from TRL 4 and above7 (e.g., Artificial Intelligence, quantum technologies, autonomous systems, robotics, advanced materials). Funding will not be provided without a clear technological objective targeting defence applications.

In 2024, 22 national websites are connected to the Platform. Additional Member States websites will be connected by the ongoing project on National Coalitions for Digital Skills and Jobs[1] by 2026. The Platform also hosts the Cyber Security Skills Academy and will host other relevant sectoral academies and initiatives.

Understanding inhabitant’s experiences of neighbourhoods to support their health and well-being

Opened

Code: 40194 | Identifier Code: HORIZON-NEB-2026-01-PARTICIPATION-03 | Programme name: 2939 | Sub-program: New European Bauhaus | Start submission calls: 05/05/2026 | End submission calls: 01/12/2026

Neighbourhoods are human-social constructs and environments. They are shaped by complex inter-connections and interdependencies of human and non-human actors in the natural and built environment they comprise.

An increasing body of research is looking at the relationship between people and the built environment, from neuro-architectural aspects of space to atmosphere and ambiance aspects in urban design and planning, influencing also the perception of beauty.

Digitalisation is also allowing to understand, map and enhance how inhabitants experience the built environment. Yet, more evidence is needed on how inhabitants react to and identify with their neighbourhoods as well as the effects of these experiences on their physical and mental health and overall well-being.

Such insights can help inform spatial planning and regeneration strategies for the green transition of neighbourhoods, including their nature-positive transformation and climate resilience, while delivering positive social and cultural impacts such as sense of community, security and belonging, or cultural identity.

Addressing homelessness through housing-led approaches aligned with the New European Bauhaus

Opened

Code: 40191 | Identifier Code: HORIZON-NEB-2026-01-PARTICIPATION-01 | Programme name: 2939 | Sub-program: New European Bauhaus | Start submission calls: 05/05/2026 | End submission calls: 01/12/2026

Social and affordable housing is being advanced in the EU, including through the Affordable Housing Initiative. Despite efforts, current policies for the green transition are failing to adequately address the housing crisis. Homelessness remains a structural challenge across Europe, with negative impacts on both individuals experiencing it (e.g. physical and mental health, social and economic conditions) and neighbourhood communities (e.g. pressure on public services, erosion of social fabric, etc.).

Research and innovation gaps in tackling homelessness range from data collection (i.e. the variety of approaches to defining, measuring and monitoring homelessness), to integrating housing-led approaches with resilience strategies for homeless populations in a climate-changing world.

Housing-led approaches cover diverse policy responses to homelessness that provide immediate and permanent access to housing, targeted prevention, and needs-based, person-centred support services across several areas of the individual’s life while giving homeless populations a high degree of choice and control.

This topic focuses on developing and/or updating housing-led approaches that apply NEB values and principles. Such approaches are expected to cover measures ranging from upstream preventive measures to those giving access to green, low-carbon, climate-resilient, health-promoting and socially inclusive housing that ensures quality of experience for homeless populations across neighbourhoods in urban, peri-urban and rural areas.
