The WNISR 2025 assesses the status and trends of the international nuclear industry. On 589 pages, 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. Eighteen authors based in eleven countries have contributed to the report. The 2025 edition of the WNISR includes special chapters on Potential Newcomer Countries, Small Modular Reactors (SMRs), Russia Nuclear Interdependencies, as well as the Fukushima Status Report and the Decommissioning Status Report.

Adding an energy system perspective, the WNISR this year also contains a special focus chapter on the Challenges of Integrating Nuclear Power into the Energy System. Here, nuclear energy is being compared with a set of renewable energy technologies, concerning the underlying physical principles as well as concerning their functions in the overall energy system. Both comparisons show: the claims for the advantages of nuclear power have no foundation in the emerging new energy system. A final chapter Nuclear Power vs. Renewable Energy Deployment corroborates these more fundamental considerations with up-to-date implementation statistics. Both these final chapters have been contributed by Ruggero Schleicher-Tappeser.
