Summary
In 2007, global interest in nuclear power staged a dramatic rebound after two decades of stagnation. Driven by converging pressures — the IPCC Fourth Assessment Report cementing scientific consensus on climate change, oil prices rising toward $100 per barrel, and surging electricity demand in Asia — governments worldwide announced major nuclear expansion plans. The United States Nuclear Regulatory Commission (NRC) received its first Combined License Applications (COLs) for new commercial reactors in 28 years, the result of streamlined licensing provisions included in the Energy Policy Act of 2005. Finland’s Olkiluoto 3 — the first new reactor to break ground in Western Europe in roughly 15 years — was under active construction (started in 2005), cementing the country’s bet on nuclear as a baseload energy source.
Globally, the International Atomic Energy Agency (IAEA) reported that approximately 435 reactors in 30 countries provided around 16% of world electricity in 2007. A further 26 reactors were under construction worldwide as of year-end 2007, the highest figure since the late 1980s. China had 4 reactors under construction in 2007 and announced plans to build 30 or more additional units by 2020. India was accelerating its civil nuclear program, further enabled by a landmark U.S.–India Civil Nuclear Agreement (finalized in October 2008 following 2007 negotiations). Russia was aggressively marketing its VVER reactor design internationally and had committed to building 26 new units domestically.
The energy policy community embraced a new rhetorical frame: nuclear power as “clean energy,” a notable inversion from the 1980s–1990s environmental opposition to the technology. Proponents noted that nuclear generation produces negligible greenhouse gases during operation — estimated at 12 grams of CO₂-equivalent per kilowatt-hour over a full lifecycle, compared to roughly 820 gCO₂e/kWh for coal and 490 gCO₂e/kWh for natural gas (IPCC 2014 lifecycle figures, consistent with 2007 estimates).
Policy Drivers
United States: Energy Policy Act of 2005
The U.S. nuclear revival was structurally enabled by the Energy Policy Act of 2005, signed by President George W. Bush, which included:
- Production tax credits of 1.8 cents per kilowatt-hour for the first 6,000 MW of new nuclear capacity during the first eight years of operation.
- Federal loan guarantees for innovative energy technologies, potentially covering up to 80% of project costs.
- Streamlined NRC licensing allowing a combined construction and operating license (COL), eliminating the separate hearings that plagued 1970s–1980s projects.
Utilities and nuclear operators — including NRG Energy, Duke Energy, and Dominion Resources — submitted the first COL applications to the NRC starting in 2007. By 2009, the NRC had received 17 applications covering 26 proposed reactors, the largest pipeline since the 1970s.
European Context
Europe’s nuclear landscape in 2007 was divided. France derived approximately 78% of its electricity from nuclear power — the highest share of any large economy — and Électricité de France (EDF) announced plans to develop a next-generation European Pressurized Reactor (EPR) domestically. Finland’s Olkiluoto 3 was also an EPR design, built by French firm Areva and German consortium Siemens. The project had already encountered construction delays by 2007: originally slated for completion by 2009, cost overruns and technical challenges pushed the expected completion date to 2012 (it ultimately reached grid connection in December 2021, 12 years late). Germany, by contrast, reaffirmed its commitment to phasing out nuclear power under its Atomausstieg policy, though this position would face political reversal in 2010 before being definitively reinstated after Fukushima in 2011.
Asia: China and India
China’s nuclear expansion in 2007 was driven by acute electricity shortages and air quality crises from coal burning. With 4 units under construction and a state-backed target of 40 GW of nuclear capacity by 2020 (roughly 5–6% of expected electricity demand), China represented the single largest national commitment to new nuclear construction in the world. The Chinese program relied on a mix of domestic designs (CNP series), licensed Westinghouse AP1000 reactors, and French EPR designs — building indigenized design capacity through technology transfer.
India’s civil nuclear program operated under international sanctions until the U.S.–India nuclear deal framework was negotiated. The 2007 Singh government signed the 123 Agreement with Washington, opening India to foreign nuclear fuel and technology in exchange for IAEA safeguards on civilian facilities. This unlocked billions in potential reactor contracts for U.S., French, and Russian vendors.
Economics of the Renaissance
New nuclear power plants in 2007 were projected to cost $2,000–$3,500 per kilowatt of installed capacity, yielding a total plant cost of $3–6 billion for a typical 1,000 MW unit. These figures proved substantially optimistic: the two AP1000 reactors under construction at Vogtle, Georgia (begun 2013) ultimately cost approximately $35 billion combined, while Olkiluoto 3 rose from an original €3 billion estimate to over €11 billion. Capital cost overruns stemmed from lost construction expertise, supply-chain gaps after two decades without orders, and the regulatory demands of post-9/11 security requirements.
Uranium spot prices, which had languished below $20 per pound for much of the 1990s and early 2000s, surged to an all-time high of $136 per pound in June 2007 before retreating — reflecting speculative investment and anticipated demand from planned reactors. The price spike ironically undercut nuclear’s fuel-cost advantage narrative in the short term, though proponents argued that fuel represents a smaller share of nuclear’s total cost structure than for fossil-fuel plants.
Aftermath and Reversal
The 2007 nuclear renaissance proved fragile. On March 11, 2011, the magnitude-9.0 Tōhoku earthquake and resulting tsunami caused three reactor meltdowns at Tokyo Electric Power Company’s Fukushima Daiichi plant in Japan. The accident — the worst nuclear event since Chernobyl in 1986 — triggered a global policy reversal:
- Germany immediately shut down 8 of its 17 reactors and committed to full phase-out by 2022 (completed 2023).
- Japan shut down all 50 of its operable reactors for safety reviews; by 2013, only 2 had restarted.
- Switzerland, Belgium, and Italy announced nuclear exit plans.
- China temporarily suspended new reactor approvals pending safety reviews, though construction resumed in 2012.
Western reactor manufacturers bore acute financial consequences. Areva (later Orano) filed for state-backed restructuring in 2017 after a decade of contract losses and Olkiluoto cost overruns. Westinghouse Electric Company filed for Chapter 11 bankruptcy in March 2017, driven largely by the troubled Vogtle and V.C. Summer AP1000 projects in the United States.
Significance
The 2007 nuclear renaissance represents a pivotal case study in energy-policy optimism confronting physical and economic reality. Three forces drove the resurgence (climate, energy security, development economics) and one force reversed it (Fukushima). The episode illustrates how large-scale infrastructure decisions made under one set of policy assumptions can be upended by low-probability, high-consequence events — a lesson that continues to shape debates over nuclear’s role in twenty-first-century decarbonization.
As of 2024, a second nuclear renaissance appears underway, this time driven by tech sector electricity demand, small modular reactor (SMR) development, and net-zero commitments. The 2007 episode offers cautionary precedents on cost and timeline optimism, and its supply-chain and skills-attrition lessons are directly informing SMR developers’ approach to standardized, factory-built designs.
