CORE 2026 is the third annual international conference dedicated to advanced research, development, and innovation in the energy sector and beyond. This year's conference will focus on the importance of zero-power research reactors for obtaining nuclear data and refining computational codes for reactor physics, nuclear medicine and other related fields for which nuclear data are crucial. The conference also aims to showcase potential applications of the CICRR (Czech International Centre of Research

Reactors) infrastructure across academic and industrial fields. The CORE 2026 conference is a continuation of the successful SUSEN conference, which has been organized by the Research Centre Řež since 2018.
