The Bugey and Saint-Alban sites could reduce their production due to the heat.

The nuclear reactors at the Bugey (Ain) and Saint-Alban (Isère) power station could reduce their production this weekend, due to the expected high temperatures and the warming of the waters of the Rhône.

PRETENDING NUCLEAR IS NOT INTERMITTENT IS POINTLESS – REPORTS EVERY YEAR SINCE 2015 IN FRANCE 

This report highlights how nuclear energy systems are becoming more intermittent due to the planet’s warming and increasing CO2 levels.

Here’s an analysis of the key points:

1. Impact of High Temperatures on Nuclear Power Production: The report discusses how nuclear power production at the Bugey and Saint-Alban sites in France may be reduced due to expected high temperatures. High temperatures can have several adverse effects on nuclear power plants, such as reducing the efficiency of cooling systems and potentially exceeding safety thresholds.
2. Warming Waters of the Rhône River: The report also mentions that the warming of the Rhône River’s waters is a contributing factor. Nuclear power plants often use nearby bodies of water for cooling purposes. As the planet warms, these water sources may become warmer, making it more challenging to cool the reactors effectively. This can lead to production restrictions and reduced output.
3. Environmental Constraints and Low Demand: The report mentions previous instances in July and August when the Bugey nuclear reactor had to be shut down due to a combination of “environmental constraints and low demand for electricity.” This suggests that the intermittency of nuclear energy is not solely related to climate conditions but also demand fluctuations.
4. Specific Thresholds for Cooling Water: The report explains that nuclear power plants have specific temperature rise and flow thresholds for the water they use for cooling. These thresholds are in place to protect the local fauna and flora. However, exceptionally high temperatures, as expected with climate change, can bring the cooling water close to or exceed these limits, necessitating production adjustments.
5. EDF’s Response to Climate Change: EDF, the company operating these nuclear power plants, has been adjusting its production to respect thermal discharge limits in response to climate change, droughts, and heat waves. This adaptation reflects the broader trend in the energy industry as it grapples with the consequences of global warming.
6. Long-term Climate Trends: The report mentions that EDF has observed restrictions on production increasing by 0.3% per year for around twenty years due to climatic reasons. This illustrates the gradual and long-term impact of climate change on the operability of nuclear power plants.
