Refuting James Hansen’s claims about nuclear power and climate change

The nuclear power industry has essentially priced itself out of the market for new power plants because of its 1) negative learning curve and 2) inability to avoid massive delays and cost overruns in market economies. This is doubly problematic because the competition — renewable power, electricity storage, and energy efficiency — have seen steady, stunning price drops for a long time.

the IEA and many others have concluded that new renewable energy will play a far bigger role in the transition.

Why James Hansen Is Wrong About Nuclear Power, Climate Progress BY JOE ROMM JAN 7, 2016 CLIMATOLOGIST JAMES HANSEN ARGUED LAST MONTH, “NUCLEAR POWER PAVES THE ONLY VIABLE PATH FORWARD ON CLIMATE CHANGE.” HE IS WRONG.

As the Nuclear Energy Agency (NEA) and International Energy Agency (IEA) explained in a major report last year, in the best-case scenario, nuclear power can play a modest, but important, role in avoiding catastrophic global warming if it can solve its various nagging problems — particularly high construction cost — without sacrificing safety.

Hansen and a handful of other climate scientists I also greatly respect — Ken Caldeira, Tom Wigley, and Kerry Emanuel — present a mostly handwaving argument in which new nuclear power achieves and sustains an unprecedented growth rate for decades. The one quantitative “illustrative scenario” they propose — “a total requirement of 115 reactors per year to 2050 to entirely decarbonise the global electricity system” — is far beyond what the world ever sustained during the nuclear heyday of the 1970s, and far beyond what the overwhelming majority of energy experts, including those sympathetic to the industry, think is plausible.

They ignore the core issues: The nuclear power industry has essentially priced itself out of the market for new power plants because of its 1) negative learning curve and 2) inability to avoid massive delays and cost overruns in market economies. This is doubly problematic because the competition — renewable power, electricity storage, and energy efficiency — have seen steady, stunning price drops for a long time.

Hansen et al also continue the myth that somehow nuclear power is being held back by environmental opposition, rather than its own marketplace failures, a point I will return to later.

Those interested in what new nuclear power can and cannot plausibly contribute to stopping global warming should start with the most objective, independent, and comprehensive analysis done in recent years — the 2015 “Technology Roadmap” from the IEA and NEA. Those agencies’ bottom is line is that, if the industry gets its act together — a big IF, given recent history — new nuclear power can play an important but limited role. This just happens to be what I’ve been arguing consistently on Climate Progress for a long, long time.

The IEA is the international body responsible for energy analysis, and one of the few independent agencies in the world with a sophisticated enough energy and economic model to credibly examine in detail the role of various low carbon technologies in a 2°C scenario (2DS) aimed at averting catastrophic climate change. ………

A key reason new reactors are inherently so expensive is that they must be designed to survive almost any imaginable risk, including major disasters and human error. Even the most unlikely threats must be planned for and eliminated when the possible result of a disaster is the poisoning of thousands of people, the long-term contamination of large areas of land, and $100 billion in damages.

No wonder very few new plants have been ordered and built in the past two decades in countries with market economies, such as the United States. And that was before the 2011 Fukushima nuclear disaster. “Japan’s embattled utility Tokyo Electric Power Co now expects the compensation costs after the Fukushima nuclear disaster to be more than $57 billion,” Agence France-Pressewrote last year. That doesn’t even include the cost of decommissioning the reactors or “cleaning up the mess from the disaster.”………..

Nuclear power remains a highly subsidized energy source that benefits from a myriad of favorable policies in this country, including taxpayer-backed disaster insurance and loan guarantees.

Should we keep working on next-generation technology? Of course. The Department of Energy and others have been working to develop small modular reactors that could start to ramp up production in 2030 and beyond. Constructed in factories, these reactors would cost $3-5 billion each. Ideally, they would be much safer than the large reactors. Yet because they are smaller and generate much less electricity, it’s not clear that their cost per kilowatt hour of delivering electricity would be much lower than current nuclear plants.

Sober climate hawks need to remember the reality that the price of nuclear power has been headed up for decades. Equally problemmatic for nukes, the price of the zero-carbon competition to nuclear power has been headed down for decades, a trend that continues even now as explained in a November DOE report, “Revolution…Now The Future Arrives for Five Clean Energy Technologies.”

The good news is that, even in the worst-case scenario, where nukes continue to price themselves out of the low-carbon market, renewables could, in theory, do the job by themselves, as Stanford’s Mark Jacobson explains.

Bottom Line: If the world is able to put itself on the 2°C path in the coming years, and if the nuclear industry can resolve a variety of issues and avoid a major disaster, then nuclear power can make a modest but important contribution. At the same time, the IEA and many others have concluded that new renewable energy will play a far bigger role in the transition. http://thinkprogress.org/climate/2016/01/07/3736243/nuclear-power-climate-change/
