Abstract (English):
This article provides an analysis of the WWER-1200 and WWER-TOI sprinkler systems. The main provisions of the NPP safety system, the purpose and operation of sprinkler systems of water-cooled reactors are considered. The similarity of the systems in ensuring the reduction of pressure and temperature in the accident localization zone, reducing the concentration of radioactive aerosols and gases in the steam-air environment under the shell, preventing or limiting the release of radioactive substances beyond the protective shell is established. It is noted that the sprinkler system with the WWER-TOI reactor has high reliability of the power unit operation in emergency situations.
