Nuclear power plants & nuclear sites

Nuclear sites are among the most closely guarded places in Europe — and among the most closely watched. Operator security, police or military guards, the regulator and the crisis centre each hold part of the picture. Meridian brings perimeter alarms, access control, drone sightings and the positions of guards onto one map, inside the operator’s own environment.

The challenge

01
Drones over nuclear sites
Today
In February 2025 a drone struck the shelter over Chernobyl’s destroyed reactor. In November 2025 up to five drones flew over the Doel plant near Antwerp for about an hour. Operations were unaffected, but the sighting passed from the operator to the police and the National Crisis Centre, each with its own records.
With Meridian
Drone sightings, guard positions and camera views come together on one map shared by operator, police and defence — each with its own layers — so a sighting is followed from the first report to the last known position.
02
Insider threats inside the fence
Today
In August 2014 someone deliberately drained the turbine oil at Doel 4, keeping the reactor offline for months. Five years later, investigators were still searching for the person responsible.
With Meridian
Badges, work orders, camera images and alarms are linked into one timeline under purpose-bound, logged access — so an unusual pattern inside the fence stands out, and an investigation starts from a complete record.
03
Many guardians, one regulator
Today
Since July 2025 soldiers have helped guard Doel and Tihange, with the federal police in charge. The operator, the guards, the nuclear regulator FANC and the National Crisis Centre each keep their own records.
With Meridian
Operator security, police and defence work from one shared picture, each with its own role and layers, and every alarm, decision and query is recorded inside the operator’s environment — evidence the regulator can inspect.

Electricity & connected data

The grid went dark. The explanation took months.

At 12:33 on 28 April 2025, continental Spain and Portugal lost power. Reconstructing the event required evidence from across the electricity system. For a Belgian operator such as ELIA, the lesson is about connecting operational context without confusing it with grid control.

Airports & critical sites

The drone is in the air. The pilot is on the ground.

A year after the first drone alarms over Belgian bases and airports, nobody has been identified. Detecting a drone is only half the problem. The other half is getting from a sighting to a person.
