23 Basic Safety Principles Evolutionary Design (*) VVER Std Mochovce 1-2 Mochovce 3-4 Approved Basic Design Mochovce 3-4 Including EU Stress Tests Improvements st step of substantial design changes (**) 2 nd step of substantial design changes EU Stress tests safety improvement measures New design of Mochovce 3&4 is Evolutionary Design like most of the Gen-III reactors nowadays under construction, since: it is firmly based on proven and well-consolidated technology of currently-operating NPPs uses such technology as starting point for the safety upgrade that puts strong emphasis on maintaining proven design to minimize technological risks * An evolutionary design is an advanced design that achieves improvements over existing designs through small to moderate modifications, with a strong emphasis on maintaining design proveness to minimize technological risks (ref.: IAEA-Tecdoc 936) ** Based on IAEA recommendations on nuclear safety improvements (IAEA-EBP-VVER-03, Safety Issues and their Ranking for VVER-440, model 213 NPP s. April, 1996)

24 Mochovce 3&4 Key improvement features Seismic design basis: 0,15 g Additional accident preventive measures Severe accident mitigation measures Light aircraft crash protection Partial secondary containment function State of the art supervision-control and protection system Design for power up-rate (up to 535 MW gross; 111.7% of CTP) with minimal HW change Radioactive waste minimisation Large number of design changes during detailed design development Significant impact on design-procurement-construction activities

25 Mochovce Units 3&4 Accident prevention measures better plant supervision, control and protection strong reduction of accident initiators Accident prevention reduction of external hazards reduction of internal hazards
