The dummy fuel is designed to be an exact replica of nuclear fuel in design, weight and dimensions, and its loading is key to checking systems for loading the real fuel as well as confirming readiness for the next stage of commissioning operations.
The dummy fuel does not contain any nuclear materials and its loading precedes the cold and hot running tests of reactor plant equipment during the commissioning process for new units, before the reactor starts up.

The loading of the fuel dummies was carried out under the supervision of Turkey’s Nuclear Regulatory Authority.
Sergei Butckikh, CEO of Akkuyu Nuclear, said: “The completion of loading of dummy fuel assemblies at Akkuyu NPP Unit 1 is a full rehearsal for loading nuclear fuel. Using the dummies, we work out procedures for handling nuclear fuel in conditions as close to operational as possible, and confirm the readiness of equipment and personnel for the next pre-launch stage.”
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 aim was for the commissioning of the first power unit of the nuclear power plant to 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. The first steam generators were shipped to the site – for unit 1 – in August 2020. Nuclear fuel was delivered to the site in April 2023. The aim is for unit 1 to begin supplying Turkey’s energy system during 2026.
When the 4,800 MWe plant is completed, it is expected to meet about 10% of Turkey’s electricity needs.

Turkey has plans for a second nuclear power plant, at Sinop, and has also been in talks with China about plans for a third plant, in the Thrace region in the country’s northwest.
The country is also developing plans for small modular reactors, with the aim of adding 5 GWe of capacity by 2050 – which would mean the equivalent of at least 16 individual SMRs.
