| Summary: | 碩士 === 國立交通大學 === 產業安全與防災學程碩士班 === 92 === This dissertation addresses the investigation of Fire Modeling on the safety related switchgear room in the nuclear power plant. The field model Fire Dynamics Simulators (FDS) is applied to simulate the characteristics of temperature variation in the area of switchgear room A and room B. The design criteria for the safety of property is founded on that whether the temperature in the vicinity of two meter above the floor is higher than 40℃. The result reveals that under the safety design basis of nuclear plant specifying the three hours fire resistive rating for walls, floors, and ceilings and sufficient ceiling space for accumulating high temperature smoke.Provided that the smoke removal system and the sprinkler system in the roomA are failure simultaneously, the smoke removal system in the room B will be employed to remove the smoke coming from the room A, which will keep the temperature near the .region of two meter height lower than 40℃ to assure the equipment normal operation in the room B. Summarizing the results above, it indicates that the function of the sprinkler system and the smoke removal system definitely have sound effects on the fire suppression, and it also provides the developing track of the fire in the scene of a fire, which gives a lot of aids in the related aspects of drafting an emergency operating procedure for fire accident to bring the reactor to a safety shutdown.
