CR-100
Research Centre Řež modular pressurized-water reactor concept of 100 MWth. The developer describes 30.5 MWe in full-condensing mode or approximately 9 MWe plus 72 MW heat in cogeneration; these operating modes are not one unqualified electrical rating. The 2023 government roadmap records early design work. Separate from Energy Well; no deployment or permission is established.
