Union of Concerned Scientists Acknowledges Importance of Nuclear Power in Carbon Emission Reduction

“The world needs a mix of renewable power sources, including one that can carry on producing power when the others can’t—the sun doesn’t always shine and the wind doesn’t always blow,” British journalist Jonathan Gornall writes in an opinion piece posted Wednesday on the Asia Times website. Gornall argues that the residents of Suffolk County in the United Kingdom would be better served by the expansion of the Sizewell nuclear power plant than by leaving a wooded area untouched.

“Given the scale and urgency of the climate challenge, we do not have the luxury of excluding nuclear from the tools at our disposal,” the leaders of the International Energy Agency and the International Atomic Energy Agency wrote in an op-ed article posted on the CNN website last Friday.

Fatih Birol, executive director of the IAE, and Rafael Mariano Grossi, director general of the IAEA, said that the COVID-19 crisis not only delivered an unprecedented shock to the world economy, it also underscored the scale of the climate challenge the world faces: Even in the current deep recession, global carbon emissions remain unsustainable.

Following U.K. Prime Minister Boris Johnson’s recent restatement of the United Kingdom’s commitment to nuclear power, BBC News chief environment correspondent, Justin Rowlatt, wrote an article aimed at separating fact from fiction regarding the safety and benefits of nuclear energy.

Among his points, Rowlatt defended the use of nuclear power to combat climate change, examined the data behind deaths from radiation exposure directly caused by the Chernobyl and Fukushima accidents, and explained that exposure to low levels of radiation is not a major health risk.

With special precautions in place due to the COVID-19 pandemic, the International Atomic Energy Agency commenced its week-long 64th General Conference yesterday with a plenary session that included remarks from Rafael Mariano Grossi, the agency’s director general.

“The latest IAEA annual projections show that nuclear power will continue to play a key role in the world’s low-carbon energy mix, with global nuclear electrical capacity seen nearly doubling by 2050 in our high-case scenario,” Grossi said, referring to a recently released agency report. “Climate change mitigation remains a key potential driver for maintaining and expanding the use of nuclear power.”

The IAEA conference runs through September 25.

Nuclear energy is faced with a number of challenges in a changing energy landscape, driven by the need to reduce carbon emissions to mitigate climate change. Renewable energy technologies are being considered as the solution to climate change and are increasingly being deployed across the world. However, renewable energy sources, particularly solar and wind, are highly variable, and deployment of these technologies has resulted in significant perturbances in the energy market, raising questions about grid stability and the adaptability of other sources to compete in a changing marketplace that prioritizes renewables. Nuclear plants, well suited for baseload operation, have demonstrated technical capability and flexibility to respond to the fluctuating demand; however, they have also discovered that the economics of such operating mode are not necessarily optimal to their financial security. On the other hand, despite contributing to the carbon emissions, the low cost of abundantly available natural gas and resultant low-cost electricity have exacerbated the economic pressure on nuclear technologies, raising questions about their survival and role in future energy systems¹.

With the Democratic Convention now under way, it is good to remember that all the leading climate scientists say that we cannot address climate change without significant nuclear power, Jim Conca noted in his opinion column on the Forbes blog site. Supporting nuclear power - or not - is a clear signal about how serious a candidate is about climate change and supporting science over mere activism, Conca said.

Dear reader:

Let’s face it. The U.S. nuclear manufacturing and supply chain is not what it once was. In the 1960s and ’70s, America was the dominant player in the global nuclear industry. Under the auspices of Atoms for Peace, U.S. companies successfully provided reactor systems and associated services to countries across the world and held significant sway over the course of future nuclear development in the international arena. America was at the top of its nuclear game.

Assuming the world takes seriously the recommendations of the Intergovernmental Panel on Climate Change, U.S. nuclear exports could be worth between $1.3 trillion and $1.9 trillion over the next 30 years, according to a new report by market research and analysis firm UxC.

Dear reader:

Welcome to the inaugural edition of the new Nuclear News! What you are seeing is truly the product of a team effort, led by our Director of Publications John Fabian and veteran Editor-in-Chief Rick Mi­chal, to fundamentally reimagine the way we bring you news and insights from the wide world of nu­clear science and technology. Nuclear News has always been the flagship publication of the American Nuclear Society, but in recent decades our visual format has gotten a little, well . . . long in the tooth.

In an entertaining “alternate history” article from The Economist posted online on July 4, a turning point in human history may have occurred on March 6, 1974. That was the day that French prime minister Pierre Messmer made an announcement that “may have saved the world from a dangerous rise in temperatures—an obscure phenomenon known in scientific circles as ‘global warming,’” noted the article. The article, What if nuclear power had taken off in the 1970s? gives a fictional account of what might have happened around the world had nuclear energy been more widely accepted decades ago.
