Safety System Analysis of Nuclear Power Plant in Bangladesh

Abstract

In this paper, the safety system and safeguards of the model VVER-1000, which is a Gen-III pressurized water reactor, designed by ROASTAM and chosen to be implemented in Bangladesh, will be analyzed. Several predefined major faults have been set to demonstrate the performance in preventing the release of harmful radiation. From simulation results, it has been observed that for moderator dilution, the malfunction is neutralized within 115 sec, for turbine trip, the malfunction is neutralized within 115 sec, for loss of AC power, the malfunction is neutralized within 53 sec, for loss of coolant accident (Cold Leg), the malfunction is neutralized within 76 sec, for loss of coolant accident (Hot Leg), the malfunction is neutralized within 53 sec, for steam turbine break inside the containment, the malfunction is neutralized within 78 sec and for steam turbine break outside the containment, the malfunction is neutralized within 110 sec.
