World Nuclear Industry Status Report 2025

The World Nuclear Industry Status Report 2025 (WNISR2025) assesses on 589 pages the status and trends of the international nuclear industry. It provides a comprehensive overview of nuclear power plant data, including information on operation, production, fleet age, construction, and decommissioning of reactors. Special focus is lent to the situation in China, France, Japan, Russia, South Korea, Ukraine, the United Kingdom, and the United States, as well as Taiwan, which completed its nuclear phaseout.

The WNISR2025 discusses the very diverse status of newbuild programs in existing nuclear nations as well as in some Potential Newcomer Countries, while the state of development of Small Modular Reactors (SMRs) is subject to a dedicated chapter.

WNISR2025 includes a special focus chapter on the Challenges of Integrating Nuclear Power into the Energy System, a compatibility analysis of nuclear energy with modern renewables-based electricity systems, complemented by a comparative analysis of Nuclear Power vs. Renewable Energy Deployment. A chapter on Russia Nuclear Interdependencies scrutinizes not only supplies from Russia but also western industries’ dependence on Russia as a client for their products and services.

The Fukushima Status Report evaluates persistent onsite/offsite challenges, 14 years after the disaster began. The Decommissioning Status Report looks at the current status of the now 218 closed nuclear power reactors. Annex 1 provides an overview by region and country of all operating nuclear programs not covered in the focus chapters.

Eighteen interdisciplinary authors based in Austria, Canada, France, Germany, Japan, Lithuania, Mexico, South Africa, Taiwan, Türkiye, and the U.S., at prestigious academic institutions like the Nagasaki University, University of British Columbia, Technical University of Berlin, the University of Johannesburg, and the University of Natural Resources and Life Sciences (BOKU), and esteemed foundations such as Bellona and Sasakawa Peace Foundations have contributed to the report, along with a data engineer, numerous proofreaders, and two artistic designers.

The foreword was provided by Letizia Magaldi, President of the Kyoto Club, Rome.
