Reactor Internal Parts of the 1st Unit of Akkuyu NPP Have Been Placed

All reactor internal parts of the 1st unit of Akkuyu Nuclear Power Plant (NGP) were placed in the design position by AKKUYU NÜKLEER A.Ş. experts to check their compliance with the requirements for safe and secure operation of the equipment.

Many large-sized equipment, especially the reactor core shaft containing the reactor core, were placed in the reactor building using the pole crane of the 1st unit. This equipment includes a baffle designed to separate the fuel bundles and limit the impact of neutron beams on the reactor vessel, and a block of protective tubes that secure the fuel bundles in their designed positions.

In the final stage of the assembly, the lidded upper block was assembled for the sealing of the main connector of the reactor, as well as for the subsequent installation of control and protection systems and in-reactor monitoring sensors. Having checked the compatibility of the main parts of the reactor, which weighs more than 600 tons in the assembled form, has a length of 19,3 meters and a diameter of 4,8 meters, experts confirmed that the actual dimensions of the equipment meet the design requirements.

Making a statement on the subject, AKKUYU NUCLEAR A.Ş. First Deputy General Director and NPP Construction Works Director Sergey Butckikh noted:

The many years of professional experience of Rosatom employees ensure that technically complex operations are carried out in the shortest possible time. This situation is confirmed by the implementation of large-scale projects around the world. The process of assembling the reactor for control is one of the most important stages in the construction of a power unit. This process is necessary to verify that the installed reactor meets all technical requirements. Each stage is an important part of the multi-stage commissioning process of the 1st unit of Akkuyu NPP. The reactor is tested twice before being loaded with nuclear fuel. We have completed the first installation test. This will be followed by the installation of fuel assembly simulators to simulate the configuration of the core. The second installation test will be carried out just before the cold-hot water circulation of the reactor plant.
