The World Nuclear Industry Status Report 2015 Summary

Core Content

The World Nuclear Industry Status Report 2015 provides a comprehensive analysis of the global nuclear power industry, including its operational status, construction trends, and comparative performance with renewable energy sources. The report highlights the stagnation and challenges faced by the nuclear sector, as well as the rapid development of renewable energy technologies and their increasing role in the global energy mix.

Main Points and Key Insights

1. Global Nuclear Industry Status

• Number of Operating Reactors: 391 reactors are currently operating globally, down from 438 in 2002.
• Installed Capacity: Total installed nuclear capacity reached 337 GW, a 5 GW increase from the previous year but still lower than the 2010 peak of 368 GW.
• Nuclear Share in Electricity Mix: Nuclear power accounts for 10.8% of global electricity generation, down from a peak of 17.6% in 1996.
• Nuclear Share in Primary Energy: Nuclear contributes 4.4% to global commercial primary energy production, the lowest since 1984.
• Nuclear Power in Japan: In 2014, no reactors operated in Japan, with 40 reactors classified as being in Long-Term Outage (LTO).
• Nuclear Power in the U.S.: 33 reactors have operated for over 40 years, and about 75% have received license extensions to a maximum of 60 years.
• Nuclear Power in France: Only 10-year extensions are granted, and there is no guarantee that all reactors will pass 40-year safety reviews.
• Nuclear Power in China: China is the largest contributor to new nuclear construction, with 42 reactors under construction as of July 2015.

2. Construction Trends

• Construction Starts: In 2014, only 3 reactors began construction, compared to 15 in 2010 and 10 in 2013.
• Construction Delays: At least 47 reactors worldwide are delayed, with many delayed by 2–9 years.
• Average Construction Time: The average time since construction started for the 62 reactors under construction is 7.6 years.
• Longest Construction Projects:
  • Watts Bar-2 (U.S.): Construction began in 1972, now over 40 years.
  • Olkiluoto-3 (Finland): Construction began in 2005, and its owner has stopped announcing startup dates.
  • Kudankulam-2 and PFBR (India): Construction started in 2004 and 2009, respectively.
  • Khmelnitski-3 and -4 (Ukraine): Construction started in 1986 and 1987, and is approaching the 30-year mark.
• Countries with Construction Delays: 10 out of 14 countries with ongoing nuclear construction have experienced delays, with most delays lasting over a year.

3. Generation III+ Reactors

• Delayed Projects: 18 reactors of Generation III+ design are under construction, with 16 delayed by 2–9 years.
• Causes of Delays: Include design issues, labor shortages, quality control problems, supply chain disruptions, poor planning, and financial constraints.
• Modularization: While intended to reduce costs and complexity, modular design has shifted quality issues to module factories rather than construction sites.
• EPR and AP1000: The EPR (European Pressurized Reactor) and AP1000 (Westinghouse) have both experienced significant delays and cost overruns.
• Cost Increases: By 2013, the projected costs of Generation III reactors had increased eightfold compared to initial estimates.

4. Advanced Reactors (SMR)

• SMR Development: The concept of Small Modular Reactors (SMR) has been around for decades, with multiple designs proposed.
• Progress:
  • U.S.: No SMR licensing applications have been submitted to the Nuclear Regulatory Commission.
  • Russia: The Floating Point Unit design was licensed in 2002, but construction has been repeatedly delayed.
  • South Korea: The SMART design has been under development for 20 years, but no units have been sold.
  • China: One high-temperature gas-cooled reactor is under construction.
  • South Africa: The Pebble Bed Modular Reactor was abandoned in 2010 after $1 billion in public spending.

5. Fukushima Status

• Fukushima Daiichi and Daini: Ten reactors at these sites are considered permanently closed.
• Fukushima Units 1–4: These units were offline for over 3 years after the 2011 disaster, with Unit 3 still not fully operational.
• Contamination and Evacuation Zones: Detailed maps and data are provided on radioactive contamination levels and evacuation zones.

6. Nuclear vs. Renewable Energy

• Renewable Growth: Renewable energy sources, particularly solar PV and wind, have seen dramatic growth in terms of capacity and generation.
• Renewable vs. Nuclear: In 2014, the world added 694 TWh of wind and 185 TWh of solar PV, both exceeding the 147 TWh added by nuclear.
• Renewables Outperforming Nuclear: In the UK, renewables (including hydropower) overtook nuclear in electricity generation.
• Population Impact: Eight countries (including China, Germany, Japan, and the U.S.) now generate more electricity from non-hydro renewables than from nuclear, representing over 3 billion people or 45% of the global population.

7. Future Outlook

• Decommissioning Trends: As nuclear fleets age, the rate of decommissioning is increasing, and new build is struggling to keep pace.
• Lifetime Projections:
  • If all reactors are shut down at 40 years, 19 units would be shut down by 2020, with 1.5 GW added capacity.
  • By 2030, 188 units (178 GW) would need to be replaced—five times the number of startups in the past decade.
• Thermonuclear Alternatives: The idea of a thorium-based nuclear value chain is still in the future, with 20 years to reach a viable solution.

Conclusion

The report concludes that the global nuclear renaissance remains a pipe dream, with Generation III+ reactors failing to deliver on cost, safety, and construction timelines. In contrast, renewables are gaining momentum and outperforming nuclear in efficiency, scalability, and cost-effectiveness. The nuclear industry continues to be outpaced by innovative energy solutions, suggesting that the future of energy may lie more in renewables than in nuclear.
