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.

NRC Resisting Europe’s Nuclear Safety Upgrades

Nuclear power plants’ reactor pressure vessels —the massive steel jars that hold a nuclear plant’s fissioning fuel—face incessant abuse from their radioactive contents. And they must be built with extra toughness to withstand pressure and temperature swings during loss-of-cooling accidents like the one that struck Japan’s Fukushima nuclear power plant in 2011. But nuclear safety authorities have recently discovered weaknesses in several pressure vessels, and their contrasting responses suggest that the ultimate lessons from Fukushima are still sinking into international nuclear power culture. This is especially true in the United States, where the Nuclear Regulatory Commission is resisting calls to mandate tougher inspection of RPVs.

Nuclear Shutdowns Put Belgians and Britons on Blackout Alert

A bad year for nuclear power producers has Belgians and Britons shivering more vigorously as summer heat fades into fall. Multiple reactor shutdowns in both countries have heightened concern about the security of power supplies when demand spikes this winter.

In Belgium, rolling blackouts are already part of this winter’s forecast because three of the country’s largest reactors — reactors that normally provide one-quarter of Belgian electricity — are shut down. Continue reading “Nuclear Shutdowns Put Belgians and Britons on Blackout Alert”

Digging into Miami’s Turkey Point Nuclear Power Station

The Society of Environmental Journalists’ Miami conference energy tour forged forward today, pursuing better understanding of South Florida’s energy options in spite of a disinvitation by local nuclear reactor operator Florida Power & Light.
