In the reactor building of the unit No. 1 of the Akku NPP in Mersin, the installation of the system of prelimination of the protective membrane (SPZO).
The company “Aka Nuclear” reported that this is part of the hermetic fence, which creates a reliable protective barrier insulating the internal protective shell of the reactor building from the external environment.
The high -tech system gives additional strength to the concrete structures of the reactor building using the junction of the beams of steel ropes.
SPZO is an important component of the security system of the protective shell (content), which is designed for extreme loads and their combinations.
The shell withstands the internal pressure of 5 kg/cm2, the external effect of the shock wave that creates a pressure of 30 kPa, and the falling large airliner.
“The system of prelimination increases the safety, sustainability, techniques of the reactor building and the nuclear power plant as a whole,” said the First Deputy General Director of Akkui Nuclear JSC, director of the nuclear power plant under construction Sergey Butsky.
He noted that the work was carried out in compliance with all technical requirements
“Akkui NPP specialists begin to start the acceptance tests of all elements to determine their strength. In addition, in the near future, the system of prelimination of the protective shell of Block No. 1 will be checked for tightness and density. All Russian modern water-watering energy reactors They have a system of internal and external protective hermetic shells, ”Butsky added.
