New EDF alert on possible nuclear production drops linked to the heat wave

Nuclear production disturbed by the heat wave. Similarly, The French electrician group EDF issued this Monday a new message announcing possible production restrictions in its nuclear fleet. Furthermore, from Tuesday, July 1, notably on the site of its Saint-Alban power station (Isère), due to the consequences of the hot weather on the temperature of the Rhône waters. Similarly, “Due to high temperature forecasts from the Rhône. However, production restrictions are likely to affect the EDF nuclear production park from Tuesday, July 1, and more particularly the site” from the boilers “From Saint-Alban (Isère)” Related by the Rhône, EDF said on Saturday in an information message. These forecasts will be refined to «J-1»said new edf alert possible nuclear EDF.

Météo-France decided on Monday to maintain orange vigilance “heat wave” In two departments. the Rhône and Isère, as since Sunday. On Thursday. when France was facing an early heat wave, EDF had the first alert message at the point of possible production decreases, especially for the Bugey (Ain) power station. Finally, no restriction was undertaken on this site this Monday, the day potentially concerned, EDF told AFP. The activity of the power plants. which pump the water from the adjacent rivers (or at sea, if necessary) for their cooling before rejecting it warmer, is framed by heating and flowing thresholds of these watercourses not to be exceeded. These thresholds are specific to each power plant and aim to protect fauna and flora.

Respect the thermal release limits – New edf alert possible nuclear

For several years. in a context of global warming, droughts and heat waves have been leading EDF, sometimes new edf alert possible nuclear from June, to adjust its production to respect these thermal releases. If the losses are relatively low. the available power mobilized can be reduced significantly during hot episodes, according to a report by the Court of Auditors of 2023 on the adaptation to the climate change of the nuclear park.

According to the group. since 2000, the losses of nuclear production for environmental causes (high temperature and low flow of rivers) represented on average 0.3% of the annual production of the nuclear fleet. During the 2003 heat wave, production losses had reached 1.43% of EDF’s annual nuclear production. Simultaneous unavailability had reached more than 6 GW. or almost 10% of the nuclear capacity installed, according to the report of the Court of Auditors.
