The first segment of the foundation slab is a circular concrete structure, a concrete ring, more than 50 metres in diameter, with a radial width of 13 metres and a height of nearly 3 metres.  Due to its size, it cannot be constructed as a single structure, so it is being built in several bays along the circumference. The concreting for the first such circular bay began on the evening of 30 July 2026. 

Another important phase is starting in the construction of Paks II Nuclear Power Plant: on 18 March the construction of the Unit 6 excavation pit to the design level began. During this, nearly half a million cubic meters of soil will be removed from the 150-meter-wide and 190-meter-long excavation pit to reach the depth of 23 meters during the excavation. Thirty units of machinery were deployed to start the works and the process will last until the end of 2026.

The ceremony of the first concrete pouring of Unit 5 took place in Paks and the new Paks nuclear power plant is now considered under construction according to the IAEA's terminology.

The forging of the reactor vessel for unit six began in one of Europe's largest automated forging plants in St. Petersburg, Russia. The production is taking place in accordance with the strictest EU and Hungarian regulations, during which the reactor vessel undergoes extremely strict, with around 700 quality checks in the process.

This happened in 2024 in the Paks II project.

Deepening of the excavation pit is continuing for the planned Unit 5 – Péter Szijjártó announced.

The Paks II. project has reached a new milestone with the arrival of one of the most important long-lead item.

Testing the crane is in the port of the nuclear power plant in preparation for receiving the core catcher.

The soil consolidation works are in progress on the site of the new units.

The pit excavation was completed up to the ground water level on the site of unit 6.
