dc.description.abstract-translatedToday‘s nuclear renaissance relies on modern Generation III+ and SMR reactors, which place high demands on safety. As a result, there is increasing pressure to upgrade older reactors, such as the VVER-1000 at the Temelín Nuclear Power Plant. One of the planned safety improvements is a new rapid depressurization system for the primary circuit in the event of a severe core meltdown accident. This system directs steam through piping into the containment. The system is shown in Figure 1. The condensed water that fills the system is slowly cooled because of heat loss to the surroundings through the outer walls. The temperature of the water is crucial for ensuring the operability of the valves that open the system immediately at the start of a core meltdown accident. The main task is to find out the temperature in these valves and determine the thermodynamics of the designed system for four diSerent conditions, representing four diSerent regimes in the primary circuit (Figure 2). This study is focused on obtaining values of temperatures from thermodynamics simulations from the CFD software Ansys Fluent.en
