The Ascó I nuclear power plant began a controlled shutdown of unit 1 this Friday to repair a faulty safety valve in the secondary circuit.

The power reduction maneuver started at nine in the morning. The objective is to address a faulty safety valve in the plant's secondary circuit. This decision was made after a test procedure identified that the valve was not correctly completing its closing action.
The Ascó-Vandellòs Nuclear Association (Anav) has determined that the intervention requires the plant to be disconnected from the electrical grid, which will occur in the coming hours. According to Anav, the incident has had no impact on workers, the public, or the environment.
The plant's manager has notified the Nuclear Safety Council of the incident, adhering to established procedures for such situations.
