摘要

火災自古至今，對人類安全影響至大，輕則造成財務的損失，重則奪去人命。
一般火場中，吸入濃煙致死比例，更高達火災總死亡人數的四成以上本研究主要係針對龍門電廠控制室所在之樓層，模擬當控制室內發生火災時，若無法即時撲滅其濃煙對整個樓層的影響，本研究依據國際防火協會所制定的使用手冊NFPA與SFPE所提供之相關參數如熱釋放速率、煙塵的參數等，並根據外界已發表論文中實驗數據設計電纜燃燒速率曲線，並比較於不同燃燒模式情形下，探討其火源燃燒材質設定為PVC (Polyvinyl chloride)下濃煙的濃度比例之差距。
本研究係以火災模擬軟體FDS (Fire Dynamics Simulator)進行模擬火災現場變化情況，其觀察於不同燃燒模式下濃煙下降速度，並計算濃煙中一氧化碳、二氧化碳濃度與火場的溫度於不同地點、不同高度之溫度變化。

Due to the fact that NPP (Nuclear power plant) is more and more important in a national security after the disaster at Fukushima Nuclear Power plant, the level of security of NPP is higher than the usual factories or other kinds of power plants.
Except the risk of nuclear reactor, the most dangerous problem of NPP is cause by fire. Because that the major source of fire is the electrical cable and because no matter what we use to transport electric power or digital signals, we must have to use cable. Especially in the control room, there are a lot of switches and cables to control the nuclear reactor or other equipments to make sure that all situations will be under proper control.
The FDS (Fire Dynamics Simulator) software was used in this study to simulate the situation. The FDS was developed by NIST (Nation Institute of Standards and Technology) to simulate the short circuit problem leading to fire at the main control room. In addition, the properties of the shielding of cable was specified in accordance with the data obtain from the hand book published by Nation Fire Protection Association (NFPA) to determine out the concentration of burning of the shielding materials resulting in smokes like carbon monoxide and carbon dioxide, together with the temperature profile of the main control room.
