Akkuyu. Installation of the protective shell of the Akkuyu NPP Unit 1 in Turkey is nearing completion. The sixth tier of the internal containment (IEC) was mounted, which is one of the main elements of the NPP safety system. “The installation operation was performed flawlessly: our builders, installers, slingers, construction crane operators once again confirmed the highest level of their professional skills. Installing a multi-ton structure with a tolerance of 1 centimeter is a very difficult task,” said Anastasia Zoteeva, Akkuyu Nuclear Director General. The sixth tier of the IEC is a metal structure consisting of 30 blocks. The total mass of the tier is 224 tons, the diameter is 44 meters. By the end of 2022, it is planned to install a containment dome at the first power unit and start commissioning.
