WWER-1000 (V-412) design has been developed in accordance with the Intergovernmental Agreement on Cooperation with India. Main equipment of the reactor plant is based on V-392 design.
The reactor plant meets the requirements of up-to-date regulatory and engineering documentation. Additional requirements of the Customer which are conditioned by specific features of the plant have been taken into account in the design. The main points of these requirements are:
- extension of the range of design basis and beyond design basis accidents, application of conventional active safety systems in addition to passive safety systems;
- consideration of seismic impacts corresponding to the Kudankulam NPP site;
