Analysis of Beyond Design Basis Accident in a Small Modular Reactor

Sammanfattning

The aim of this thesis is to investigate Beyond Design Basis Accident of Small Modular Reactor in a Nuclear Powerplant. As the energy industry seeks innovative solutions for reduction of carbon emissions, nuclear solutions have gained attention as considerable alternatives. However, ensuring the safety of these systems is a tough challenge. By modeling and analyzing nuclear reactor behaviour with Symbolic Nuclear Analysis Package and MELCOR programs, this thesis provides insights into Beyond Design Basis Accidents for a Nuclear Powerplant. The research results in determination of the amount of released radionuclides into the containment in case of a station blackout scenario and also the estimated evacuation time for the crew of the Nuclear Powerplant.
