How many times have you read an article and discovered that the label on the package didn’t match the meat? Here’s an open secret from the news biz: that story’s writer may have also cringed. Writers often don’t see the headline until it runs, and we’re not always ecstatic about the angles editors choose to hook eyeballs.

Take this headline that topped a story today on China’s nuclear power sector in Technology Review magazine:

China’s losing its taste for nuclear power. That’s bad news.

Personally I’d call China’s anti-nuclear turn “sad” rather than “bad.” But what do I know? I only wrote the story!

Whatever the headline, my article shows that the same woes killing Western nukes now confront the technology in China. As the editors’ spot-on subhed puts it: ‘Once nuclear’s strongest booster, China is growing wary about its cost and safety’.

The coming downturn is hard to recognize amid a flurry of new reactor startups, and nuclear industry players worldwide have been slow to acknowledge it. It means that China’s planners may no longer count on reactor power to wean the world’s leading greenhouse gas emitter off of coal and oil. And if one big option for decarbonizing energy systems may be biting the dust, that puts more pressure on the remaining options (eg. solar panels and wind turbines) and on innovators conjuring up new options.

As for whether dropping the nuclear option is bad or sad? I’d prefer to let the readers decide. Have your own look online, or pick up Technology Review’s January 2019 Special Issue on China.

U.S. Deep-Sixes Plutonium Fuel Plant

The U.S. Department of Energy (DOE) has terminated construction of a facility designed to transform 34 metric tons of surplus military plutonium, enough for about 17,000 nuclear weapons, into fuel for nuclear power plants. The Aiken, South Carolina project began in 2007 and was at least $2.6-billion over its $4.9-billion estimated cost and still years from completion — akin to the troubled pair of Westinghouse AP1000 nuclear reactors under construction in nearby Vogtle, Georgia and another pair killed last year at South Carolina’s VC Summer plant.

Mismanagement is only half the story, however, according to Edwin Lyman, a physicist and nuclear expert at the Union of Concerned Scientists in Washington. Lyman says the plant was also plagued by safety, technology and regulatory challenges specific to handling plutonium. Trace amounts of plutonium cause lethal cancers and its 24,110-year half-life means small releases could render lands uninhabitable for generations making it an attractive material for would-be makers of ‘dirty’ bombs.

Double Milestone for Safer Reactors

Call it the world’s slowest photo finish. After several decades of engineering, construction flaws and delays, and cost overruns—a troubled birth that cost their developers dearly—the most advanced commercial reactor designs from Europe and the United States just delivered their first megawatt-hours of electricity within one day of each other. But their benefits—including safety advances such as the AP1000’s passive cooling and the EPR’s airplane-crash-proof shell—may offer too little, too late to secure future projects.

Palmetto State’s $9-bn Nuclear Boondoggle

“Public trust is at stake here, folks.” That’s how South Carolina’s top power industry regulator described the gravity of local utilities’ decision to walk away from a pair of partially-built nuclear reactors, according to Charleston’s Post and Courier. Public Service Commission chairman Swain Whitfield added that the reactors’ cancellation after $9 billion of investment — more than the state’s annual budget — “is going to shatter lives, hopes and dreams” in South Carolina. South Carolina-based Santee Cooper and SCANA’s abandonment of their pair of new reactors, announced on Monday, also have broader ramifications for the nuclear industry’s self-declared “nuclear renaissance.” The cost overruns and delays afflicting this project and a sister project in Georgia drove the reactor designer and builder Westinghouse Electric Co. into bankruptcy. Cost overruns and political concerns are also squeezing nuclear suppliers from France, South Korea, and Russia. Continue reading “Palmetto State’s $9-bn Nuclear Boondoggle”
