#French #NuclearPower production expected to be reduced on Wednesday

PARIS, Aug 12 (Reuters) - "Power production at France's #Bugey3 #nuclear reactor in the east of the country is expected to be reduced by 500 megawatts (MW) on Wednesday, data from operator #EDF showed on Tuesday, as high river temperatures reduce the plant's ability to intake cooling water.

"A #heatwave throughout #France has led to multiple warnings of power reductions at a number of #NuclearPlants, particularly on the #RhoneRiver in the east and the #GaronneRiver in the west.

"The #Bugey 3 reactor has a maximum capacity of 910 MW, which will be reduced to 410 MW from 2:30 p.m. (1230 GMT) to midnight on Wednesday as the reactor is required to meet environmental safety measures, EDF's data showed.

"The high water temperature warnings for the #SaintAlban plant - down river of the Bugey site - and the #Golfech site in the west were moved to August 14, but restrictions have not yet been issued.
Average temperatures in the country are expected to continue to peak throughout the week, reaching a high of 28.5 degrees Celsius (83.3°F) on Saturday, LSEG data showed.

"#NuclearPower accounts for about 70% of total French power consumption annually, but August is the main holiday season throughout the country and electricity demand is often limited."

We’re having a #heatwave...

And #NuclearPower can’t cope. Worse still, it’s actually a liability under ever more extreme climate conditions, write Karl Grossman and Harvey Wasserman

"At the core of the latest attempted 'renaissance' of nuclear power is the big lie that #AtomicReactors are an answer to #GlobalWarming. In fact, they are significant sources of heat.

"There are more than 400 nuclear power plants in the world today that fission atoms at 300 degrees Centigrade, (572 degrees Fahrenheit). More are under construction or proposed. As the International Atomic Energy Agency states, 'water-cooled reactors offer heat up to 300 degrees Celsius. These types of reactors include pressurized water reactors (PWRs), boiling-water reactors (BWRs), pressurized heavy-water reactors, and light-water-cooled graphite-moderated reactors (LWGRs).'

"Some heat is absorbed in the water—drawn from water bodies—used to cool these nuclear power plants and then returned, still with considerable heat, to #rivers or #seas.

"The heatwave going on in recent weeks in Europe, in combination with this discharge of heated water from nuclear plants, has caused #NuclearPlants there to shut down.

"Consider these headlines from recent days:

" '#France and #Switzerland shut down nuclear power plants amid scorching heatwave,' was the July 3rd headline on Euronews. As the piece explained: “To cool down, nuclear power plants pump water from local rivers or the sea, which they then release back into water bodies at a high temperature. However, Europe’s ongoing heatwave means that the water pumped by nuclear sites is already very hot, impacting the ability of nuclear plants to use it to cool down. On top of this, nuclear sites run the risk of posing a dangerous threat to local #biodiversity, by releasing water which is too hot into rivers and seas.'

"A New York Times article, also dated July 3rd, related how in Europe, 'operators shut down one of the two reactors at the #Golfech nuclear power plant in southern #France after forecasts that the #GaronneRiver, from which it draws water and then discharges it after it is used in the plant as coolant, 'could top…82 degrees Fahrenheit.' The Times continued: 'The #Beznau Nuclear Power Plant in #Switzerland, built along the #AareRiver followed suit, shutting down one of its reactors on Tuesday and the other on Wednesday.' "

The Garonne River: Bordeaux’s Lifeline

Importance and Dimensions The Garonne River, winding through the city of Bordeaux, is one of France's most important waterways. Stretching over 600 kilometres, the river originates in the Spanish Pyrenees and flows through southern France before merging with the Dordogne River to form the Gironde estuary.

Hot river water curbs output at French #NuclearPlant

By Forrest Crellin
August 2, 2024

PARIS, Aug 2 (Reuters) - "Electricity production at the #Golfech nuclear plant in southern #France was reduced by 1 gigawatt (GW) on Friday, EDF data showed, after the utility said high #WaterTemperatures on the #GaronneRiver could mean reduced output until Aug. 10.

"The restrictions are the first this year linked to high temperatures, which typically represent less than one percent of annual production.

"Nuclear output in France has been relatively consistent this year, following years of disruption caused by extended maintenance.

"EDF sometimes limits production when temperatures are near a threshold that varies depending on the nuclear plant.
On Thursday it extended a warning of possible reduced output that had been expected to end on Saturday.
EDF was not immediately available for comment.
LSEG data showed that the 28°C (82.4 Fahrenheit) temperature limit for the River Garonne that cools Golfech was breached once on July 31.

"Only one of several forecasts showed temperatures surpassing that level over the next week."

"'Dropping temperatures in France should ease the pressure and allow the plant to return to normal generation levels sooner. However, the beginning of next week has temperatures rising once again and problems could start once again,' LSEG analyst Ulrich Weber said."
