Concreting completed for the containment dome of Akkuyu unit 1

12 November 2024

Concreting of the outer containment dome of the first unit at Turkey's Akkuyu nuclear power plant took 104 days, with 3511 cubic metres of high-strength self-compacting concrete mix poured.



Two tower cranes, six concreting booms and 34 mixer trucks were used during the work on the first of the four VVER-1200 units being constructed at the site.

The metal dome for the building was lifted into place in two stages in August and September.

Following the concreting, the dome has a thickness of 1.5 metres.

Installation de la turbine pour le 1er réacteur.

Turbine installed at Turkey's Akkuyu unit 1

17 December 2024

Turbine installation has been completed at the first unit of Turkey's Akkuyu nuclear power plant, paving the way for pre-launch tests and then cold-hot testing of the reactor unit.

The past year has seen all the main equipment installed in the reactor and preparations for pre-launch tests with dummy nuclear fuel are under way. Last month concreting of the outer containment dome was completed.

Alparslan Bayraktar, Turkish Minister of Energy and Natural Resources, said: "We need nuclear energy to meet Turkey’s growing energy demand and achieve the goal of zero emissions by 2053. The Akkuyu NPP project is one of the largest projects in our country ... Turkey and Russia are working on this project as a single team with all stakeholders."

Alexey Likhachev, director general of Rosatom, said: "2024 has become a year of not only serious challenges but also great achievements for the Akkuyu NPP. We have witnessed one of the key events at the site - the completion of the turbine installation. This is a necessary step on the long road to launching the power unit. We will continue to make every effort to ensure that the first nuclear power unit starts operating in Turkey in the near future. It will provide millions of consumers with stable low-carbon energy."

In a report on the event, Russia's Tass news agency quoted Likhachev as saying that the progress on the turbine for the first unit at Akkuyu had been achieved despite problems caused by the impact of sanctions on supplier agreements with Germany's Siemens. This had led to a change in the supply chain: "We leveraged our competitive advantage because no other organisation has the experience we do in integrating elements of international projects ... we turned to our Chinese friends, who extended a helping hand to us," Tass reported Likhachev as saying.

The background

Akkuyu, in the southern Mersin province, is Turkey's first nuclear power plant. Rosatom is building four VVER-1200 reactors, under a so-called BOO (build-own-operate) model. According to the terms of the 2010 Intergovernmental Agreement between the Russian Federation and the Republic of Turkey, the commissioning of the first power unit of the nuclear power plant must take place within seven years from receipt of all permits for the construction of the unit.

The licence for the construction of the first unit was issued in 2018, with construction work beginning that year. Nuclear fuel was delivered to the site in April 2023. Turkey's Nuclear Regulatory Agency issued permission for the first unit to be commissioned in December, and in February it was announced that the reactor compartment had been prepared for controlled assembly of the reactor - and the generator stator had also been installed in its pre-design position.

The aim is for unit 1 to begin supplying Turkey's energy system in 2025. When the 4800 MWe plant is completed, it is expected to meet about 10% of Turkey's electricity needs, with the aim that all four units will be operational by the end of 2028.

Final assembly under way for Akkuyu 4’s reactor vessel

Friday, 22 August 2025

Fabrication of the control assembly for the reactor vessel has begun for the fourth unit at the Akkuyu nuclear power plant in Turkey. Rosatom said it will be the 250th nuclear reactor manufactured in Russia.

La première tranche de la centrale nucléaire d'Akkuyu est terminée

26/09/2025,

Les travaux majeurs de la première unité de la centrale nucléaire d’Akkuyu, située dans la province de Mersin, sont désormais achevés. Selon Anton Dedusenko, président du conseil d’administration de la société Akkuyu Nuclear JSC, les systèmes et composants sont actuellement testés pour garantir leur conformité aux standards internationaux.

Lors de la Semaine atomique mondiale à Moscou, Dedusenko a précisé que les quatre réacteurs du site étaient construits simultanément. La priorité actuelle est la mise en service du premier réacteur, désormais en phase de pré-mise en service, impliquant une batterie de tests complets.

Le responsable a souligné que les infrastructures hydrauliques et électriques essentielles à l’alimentation des réacteurs sont presque terminées. Ces installations, véritables "systèmes nerveux" de la centrale, devraient être pleinement opérationnelles d’ici la fin 2025.
Vers la fourniture du premier kilowatt atomique turc
La mise en service d’une unité nucléaire suit un protocole strict et progressif. "Les systèmes et composants sont contrôlés pour garantir leur conformité aux critères de sûreté nucléaire", a indiqué Dedusenko. Ces étapes visent à assurer un fonctionnement fiable et sécurisé pour plusieurs décennies.

Le premier kilowatt atomique pourrait être injecté dans le réseau national turc dès 2025. Les retards précédents, liés à des livraisons d’équipements électriques en provenance de Chine, ont été surmontés, permettant à l’équipe de maintenir le calendrier global du projet.

Cette avancée conforte la Türkiye dans sa volonté d’assurer une indépendance énergétique durable tout en confirmant sa place dans le cercle restreint des puissances nucléaires mondiales.

Les entreprises turques émergent sur la scène nucléaire mondiale
Au-delà de l’ingénierie, le projet Akkuyu représente un tremplin pour les entreprises turques. D’après Dedusenko, la part de localisation, initialement estimée à 4 milliards de dollars, atteint désormais 11 milliards, incluant les retombées fiscales versées à la Türkiye.

Environ 2 000 entreprises locales participent au projet, fournissant matériaux, équipements et services. Plusieurs d’entre elles, après avoir modernisé leurs processus pour répondre aux exigences nucléaires, exportent désormais leur savoir-faire.

Türkiye’s Akkuyu Nuclear Plant nears commissioning of first reactor, eyes 2026 start
.................
Next steps in Akkuyu: fuel loading, power generation
Butckikh explained that the next phase will involve verifying the operation of certain equipment units and safety systems before moving forward with fuel loading.

"After verifying the operation of certain equipment units and safety systems, we will proceed with loading fresh nuclear fuel, physically starting up the plant, and reaching the minimum controllable power level," he said.

He added that once the reactor reaches nominal power, the turbine will be activated, operating modes will be tested, and the plant will transition into commercial electricity production.
