Zaporizhzhia NPP is disconnected from Ukraine’s grid, operating on diesel generators

On September 23 at 16:56, the only high-voltage line connecting the Zaporizhzhia nuclear power plant to Ukraine’s power system was disconnected. The Ukrainian Ministry of Energy reported that the plant switched to emergency power from diesel generators.

Power Supply Issue

The Zaporizhzhia nuclear power plant found itself on the brink of a critical state. The Ministry of Energy of Ukraine stated that “ZNPP switched to self-sustaining power from diesel generators,” emphasizing that this represents a significant violation of normal operation.

Absolute dependence on diesel fuel indicates serious risks both for the plant and the environment. Automation and remote systems can no longer operate at full capacity, highlighting the vulnerability of the facility.

Action Plan

As noted by the department, emergency recovery work will begin as soon as the safety situation allows. However, the order and timing of these works remain in question.

Radiation Safety Situation

According to information from the UNIAN Agency, the fuel reserves necessary for the operation of diesel generators are calculated to last a maximum of ten days. This creates a real threat of nuclear fuel reprocessing and a possible radiation release in the event of further power loss.

Expert Opinion

Dmytro Humeniuk, head of the safety analysis department at the State Scientific and Technical Center for Nuclear and Radiation Safety, warned of potentially catastrophic consequences. In the failure of power supply systems, he sees a real threat to everyone in the risk zone.

Historical Reference

This is already the tenth instance of ZNPP being disconnected from the Ukrainian power system since the occupation by Russians. The state of the facility raises concerns not only among Ukrainian authorities but also among international organizations.

The consequences of such disconnections can be irreversible and affect not only Ukraine but also neighboring countries. The lack of safe management and monitoring of the nuclear plant’s operation can have catastrophic consequences for the safety of the entire region.
