Key Takeaways
- 43% of respondents in the 2023 Nuclear Energy Institute (NEI) survey selected “sustainable energy/fuel cycle” as the leading priority for nuclear communications
- 1.5x increase in nuclear sector recycling capacity by 2030 is projected in the OECD/NEA's 2020 report scenario for expanding recycling and related fuel-cycle infrastructure (global recycling capacity expansion factor)
- 1.3 gCO2e/kWh is the lower bound for nuclear life-cycle emissions cited within IPCC AR6 (life-cycle mitigation chapter comparison)
- 2.1% of global electricity generation in 2022 came from nuclear power (share of generation used in IEA tracking)
- 2.7% of electricity generation in the United States was provided by nuclear in 2023 (US EIA data, annual share)
- EU ETS verified emissions reporting: power-sector installations reported regulated CO2 emissions totals used in the European Commission’s verified emissions dataset (nuclear plants fall under the EU ETS regime for specified activities)
- 1.6% of global GHG emissions were attributed to the energy sector in the IPCC AR6 WG3 context for mitigation scenarios (baseline reference used for sector framing of decarbonization), relevant for comparing nuclear lifecycle emissions
- In the European Commission’s taxonomy, nuclear energy is included as a transitional activity for eligible conditions (including radiation protection and waste management requirements), with a 2022 formal Delegated Act establishing criteria
- NEA/IAEA: The planned number of geological disposal facilities in operation is expected to increase to dozens globally by mid-century per the NEA/IAEA “status and trends” assessment (disposal facility deployment metric)
- The IAEA reports that 160 countries have reported on radioactive waste inventories (including spent fuel and operational wastes) as part of its Radioactive Waste Management (RWM) program information exchange
- 8.9% of global nuclear spent fuel is reprocessed in a year based on OECD/NEA historical reprocessing volumes vs. total arisings (reprocessing fraction metric in NEA data summaries)
- 2022: Nuclear power generated 2,532 TWh of electricity globally (IEA electricity data)
- 2023: Nuclear power generation in the US was 772.0 TWh (US EIA annual net generation)
- Cooling water withdrawal for nuclear plants is often reported in the US as on the order of hundreds to thousands of cubic meters per MWh depending on cooling technology (reported range compiled in USGS water use assessments)
- IEA reports that the global nuclear fleet’s average availability has been about 80% over recent years (fleet utilization metric cited in IEA nuclear energy updates)
Nuclear sustainability priorities are rising alongside low life cycle emissions, recycling plans, and stronger waste management.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
