Sažetak
During design basis events (LOCA, MSLB) in containment exists possibility for additional condensation within compartments and enclosures with different electrical equipment that can result in submergence of its parts and possible malfunction. The condensation within limit switch compartments (valve actuators) and attached electrical conduits during limiting LOCA and MSLB accidents in containment was analyzed using Gothic computer code with the assumptions corresponding to the ones used to generate containment EQ profiles for thermalhydraulic EQ parameters. The outcome of the analysis is volume of the liquid within the compartment and corresponding liquid level before and after additions of bottom openings (T-drains) required to drain condensed liquid. Different compartment sizes were analyzed during different LOCA and MSLB scenarios. After addition of bottom openings maximum possible condensed liquid level can not cause actuator malfunction.
