Evaporation and condensation model for a cooling system of the LiPb cold trap device

Original language description

The eutectic liquid metal LiPb is considered as one of the tritium breeders of the first fusion power reactors. The flowing liquid metal dissolves alloying elements of the structural steels and thus causes their corrosion. The proposed type of the cold trap is a device providing extraction of corrosion products from liquid metal by gravity separation, which occurs at lower temperatures than the operating conditions of LiPb in the fusion reactor blankets. The developed cold trap consists of three loops. The primary loop is designed for LiPb liquid metal flow purification. The proposed cooling of the primary loop is based on the water-steam natural convection with two basic principles; evaporation and condensation. The evaporation section supports the optimal heat transfer from the primary loop and the condenser section removes heat from the trap body to the third loop. To ensure the required conditions at all operational thermal loads the presence of the inert gas (argon) in the secondary loop is provided. However, the addition of the inert gas into the steam significantly reduces the heat and mass transfer to the condenser and consequently leads to degradation of the heat removal potential of the condensation. A 0D model is developed and applied to solve these processes. Validation of this model for the operational conditions and achieved results for the cold trap operational states are analyzed and discussed.
