Extreme Heat Shuts Down Some Nuclear Reactors in Europe
Late on Sunday, operators shut down one of the two reactors at the Golfech Nuclear Power Plant in southern France after forecasts that the Garonne River, from which it draws water, could top 28 degrees Celsius, or roughly 82 degrees Fahrenheit.
The Beznau Nuclear Power Plant in Switzerland, near the Aare River near the country's northern border, followed suit, shutting down one of its reactors on Tuesday and the other on Wednesday.
Both plants are designed to keep their reactors at safe temperatures by cooling them with river water, which is then pumped back out at higher temperatures. Regulations in both countries require operators to reduce energy production when the rivers get too hot, in order to protect downstream environments.
The operator of the Beznau plant, Axpo, said that 'excessive warming of the already-warm river water during hot summer periods is to be prevented in order not to place additional strain on flora and fauna.' In a statement, Axpo confirmed that a limit of 25 degrees Celsius had been exceeded for several days in a row.
Other river-cooled nuclear reactors, including one at the Bugey plant in southeastern France, have reduced their power generation. Temperatures across Europe have regularly exceeded 100 degrees Fahrenheit this week, though forecasters say relief is on the way over the weekend.

Clouds Are Cool, but Have You Ever Seen One Like This?
The dramatic mass moving ashore one afternoon in Portugal this week looked like something out of a movie: dozens of people who had gathered at a beach to escape an oppressive heat wave stared up at the sky as it inched toward them. Was an alien ship about to emerge? Should someone call Jeff Goldblum? But it was a cloud that stopped people in their track — a 'roll cloud,' to be specific, which more typically form from thunderstorms. In this case, the cloud formed at the intersection of the ocean and the land as a cool, moist air mass moving over the Atlantic Ocean collided with dry, hot air over southwestern Portugal, which, like much of Europe, has been sweltering in a weeklong heat wave. The roll cloud is created by a wave in the atmosphere that causes a rising and sinking motion over adjacent areas, allowing the clouds to form and appear to roll forward. You can see that below in an aerial image, where the crest and trough of the cloud are visible and resemble an ocean wave. Sean Waugh, a severe storms expert with the National Severe Storms Laboratory who typically encounters such clouds as thunderstorms move over the Plains in the United States, compared the clouds to what happens when a rock is dropped in a pond. The cloud is just the leading edge of a ripple in the atmosphere. While the cloud in Portugal occurred in the afternoon, it was most likely a 'morning glory,' a specific type of cloud often associated with roll clouds that more commonly occurs after sunrise in the Gulf of Carpentaria in Australia. This type of roll cloud can stretch many hundreds of miles long, which is why it was seen up and down much of the central coast of Portugal. The heat wave that has swept Europe this week has led to multiple deaths and helped fuel wildfires in Greece, Turkey and Portugal. High temperatures are expected to spread east in the coming days.

Extreme Heat Shuts Down Some Nuclear Reactors in Europe
A record-breaking heat wave in Europe is warming up the river water that some nuclear power plants use for cooling, prompting operators to shut down at least three reactors at two separate sites. Late on Sunday, operators shut down one of the two reactors at the Golfech Nuclear Power Plant in southern France after forecasts that the Garonne River, from which it draws water, could top 28 degrees Celsius, or roughly 82 degrees Fahrenheit. The Beznau Nuclear Power Plant in Switzerland, near the Aare River near the country's northern border, followed suit, shutting down one of its reactors on Tuesday and the other on Wednesday.

Wildfires rage on Greek island of Crete amid deadly European heat wave
Amid a deadly heat wave across Europe, wildfires are burning in countries including Spain, Greece and Turkey. Hundreds of firefighters in Greece have been dispatched to battle a massive blaze exacerbated by high temperatures and gale-force winds. Some 230 firefighters — assisted by drones, 10 helicopters, the Greek police and emergency medical workers — were deployed to Crete after a fire broke out Wednesday, prompting evacuations across the region, according to Greek authorities.
