The purpose of this study is to analyze and evaluate the pressure, flow rate and volume flow rate of the designed dry room by computational fluid analysis and to apply the results to dry room construction and drying system design. The Korea Atomic Energy Research Institute is studying pyro-process technology as a method for recycling spent fuel and minimizing waste, which is performed in a salt environment. The salt causes corrosion, so the moisture in the air must be removed. Dry glove boxes are therefore prepared for small-scale studies, but small- and medium-scale studies require drying rooms because workers are considered access. The long-term robustness and salt corrosion performance of chemical processing equipment is verified in this room under high temperature conditions. When a problem occurs, the operator immediately goes inside and identifies the problem. Compared to the drying room in general industry, since the operator does not need to go in and out frequently, we designed a hybrid dehumidification system that combines a room with airtightness and compressed dry air. This system can maintain the ultra-low humidity by supplying compressed air without activating the dehumidifier when the operator does not go inside the room.
