- EDF has taken precautionary measures at the Flamanville nuclear facility in response to the approaching Storm Goretti.
- The company disconnected production units 1 and 3 from the grid after reducing their power output.
- According to the company, these actions were taken in strict adherence to established protocols designed to address severe weather forecasts.
- The shutdown is a standard safety procedure intended to ensure the integrity of the facility and the stability of the power grid during high-wind events.
Quick Summary
EDF has initiated a shutdown of specific production units at the Flamanville nuclear power plant. This decision was made in anticipation of Storm Goretti, a weather system expected to impact the region.
The utility company disconnected units 1 and 3 from the electrical grid. Prior to disconnection, the power output of these units was reduced. The company stated that these measures were taken "conformément aux procédures prévues pour faire face aux prévisions météorologiques annoncées" (in accordance with planned procedures to deal with announced weather forecasts).
The operation is a preventative safety measure. It ensures that the facility remains secure during the storm. It also protects the wider electrical infrastructure from potential fluctuations caused by severe weather.
Operational Response to Weather Conditions
The Flamanville nuclear facility has adjusted its operations in response to the incoming storm. EDF confirmed that specific production units were taken offline.
The decision to stop production was not sudden. It followed a standard protocol triggered by weather forecasts. The company reduced power levels before fully disconnecting the units.
This approach is designed to maintain grid stability. It also ensures the physical safety of the plant infrastructure against high winds and heavy rain associated with Storm Goretti.

Technical Details of the Shutdown
The shutdown affected two specific units at the site. Unit 1 and Unit 3 were the specific assets involved in this operation.
The process involved two distinct steps:
- First, the power output was reduced.
- Second, the units were disconnected from the production network.
- Finally, the units entered a safe standby state suitable for the weather conditions.
These steps are routine for nuclear facilities located in areas prone to severe weather events. The goal is to minimize risk while maintaining the ability to return to service quickly once conditions improve.
Safety Protocols and Procedures
Safety is the primary driver for these operational changes. EDF adheres to strict guidelines when severe weather is predicted.
The procedures mentioned by the company cover various scenarios. These include:
- Pre-emptive power reduction
- Disconnection from the national grid
- Securing on-site equipment
By following these steps, the facility avoids potential damage from grid instability. It also prevents any strain on the reactors during the storm. The facility remains monitored closely during the weather event.
Context of Storm Goretti 🌪️
Storm Goretti represents a significant weather event for the region. Meteorological forecasts prompted the Flamanville operators to act.
Nuclear power plants are critical infrastructure. Consequently, they operate with an abundance of caution. When high winds or flooding are possible, operators prefer to secure assets rather than risk operational anomalies.
The shutdown of Unit 1 and Unit 3 demonstrates this cautious approach. It ensures that human error or mechanical stress is minimized during the storm.
Conclusion
EDF has successfully implemented safety measures at the Flamanville site. The disconnection of production units 1 and 3 was executed as planned.
The facility is now in a secure state to weather Storm Goretti. The actions taken reflect standard industry practice for protecting nuclear infrastructure during extreme weather. Operations will likely resume once the storm has passed and safety checks are completed.
Frequently Asked Questions
