Nuclear Energy: Assuring Energy, Health and Food May 06 - 10, 2024 Escola de Guerra Naval (EGN) | Rio de Janeiro - RJ


INAC 2024 serves as an intellectual platform for a profound exploration of nuclear energy's multifaceted sides, particularly its role as a catalyst for industrial growth, employment generation, and socio-economic advancement. Additionally, the conference aims to highlight the invaluable contributions of nuclear science and technology to environmental sustainability in regions and nations where these resources are deployed.

INAC 2024 encompasses three distinct yet interconnected technical meetings: the XXIII Meeting on Nuclear Reactor Physics and Thermal Hydraulics (XXIII ENFIR), the XVI Meeting on Nuclear Applications (XVI ENAN), and the VIII Meeting on Nuclear Industry (VIII ENIN). Additionally, we are delighted to present the tenth edition of the Junior Poster Technical Sessions, specially designed for undergraduate students from various colleges and universities. This platform allows them to share their invaluable research findings, nurtured under the guidance of esteemed nuclear researchers from Brazilian Institutions.

Complementing the conference program, Expo INAC 2024, our renowned technical and commercial exhibition, will run parallel to INAC 2024 itself. This presents an invaluable opportunity to network with delegates, strengthen ties with existing partners, forge new relationships, display products and services, unveil innovative solutions, and explore international collaborations that can form the basis of lasting alliances.

We extend our sincere gratitude to all contributors who have played a role in the publication of the Proceedings – the authors, the diligent board of referees, and the dedicated editorial committee. We would also like to commend the Chairs and Co-Chairs of the technical meetings for their unwavering commitment to ensuring the success and technical excellence of INAC, the largest nuclear event in South America.

We acknowledge, with deep appreciation, the support of our sponsors, government agencies, industries, and institutions, both past and present, whose direct and indirect contributions have been instrumental in ensuring the triumph of this event.

ABEN and the INAC 2024 Organizing Committee recognize that the true essence of this meeting lies in your participation. We thank you in advance for sharing your valuable time with us and extend our warmest wishes for an enriching and enjoyable experience during your visit to Rio de Janeiro, RJ.

We cordially invite you to be our honored guests at INAC 2024!
