The reactor cavity and Primary room Heat Transfer System (PHTS) cells of FBR are designated as water prohibited area to prevent sodium-water reaction phenomena.
In Monju, fluorocarbon is used as a refrigerant instead of water refrigerants for Reactor Building (R/B) Heating, Ventilation, and Air Conditioning (HVAC).
R/B HVAC chiller system using fluorocarbon is characteristic equipment for FBR, and there is no example in light water reactors.
In this study, we evaluated the running performance of R/B HVAC Chiller System by using about 20 years Plant data as an Evaluation of “Monju” Research Plan.
