中文摘要 隨著時代的進步,在未來20年內對於電力的需求會大幅增加,核能發電目前在台灣的能源結構依然是不可或缺的一部分,它比起再生能源發電,提供較為穩定、高效率的發電模式,也不會像火力發電產生大量二氧化碳,使全球溫室效應加劇,違背未來節能減碳的趨勢,核能發電雖然有許多優點,也有最主要的缺點即是輻射污染的問題,隨著核能發電的發展,開始讓人們對於一旦核能電廠發生重大事故時的,本身結構是否安全及輻射是否可能會外洩等問題產生疑慮,在台灣,龍門電廠的採用的是進步型沸水式反應爐,有別於目前運轉中的核一廠、核二廠的沸水式反應爐和核三廠的壓水式反應爐,採用新的反應爐機組和不同的圍阻體結構設計,目前在國內對於龍門電廠鋼筋混凝土圍阻體的研究分析還不是很完善,因此本文利用有限元素軟體ABAQUS分析探討進步型沸水式反應爐之鋼筋混凝土圍阻體的極限耐壓能力,了結圍阻體內承壓的結構行為,並討論不同的結構模式及高溫的情況下,找出圍阻體承壓之極限耐壓能力及其裂縫位置。除了靜力的分析之外,並考慮到未來圍阻體會受到地震等動態負載,探求圍阻體在一些不同邊界條件的自然振動頻率,以了解其動態特性避免共振現象的發生,希望能對日後關於龍門電廠鋼筋混凝土圍阻體之研究有一參考的依據。
英文摘要 Nowadays, nuclear electricity generation is indispensable to the energy structure in Taiwan. The nuclear electricity generation can stably supply a large amount of electricity, and yet have less impact on the environmental pollution. With the increasing popularity of nuclear electricity generation, people have put more emphasis on the safety issue of the nuclear power. For the first time in Taiwan, Lungmen Nuclear Power Plant uses the Advanced Boiling Water Reactor. The type of this reactor and the structure design of its containment vessel are both different from all the other nuclear power plants in Taiwan. This study uses ABAQUS finite element analysis software to research into the ultimate pressure strength and the natural frequency of the containment vessel of Lungmen Nuclear Power Plant. By plotting a radial contour diagram and an axial contour diagram of the Reinforced Concrete Containment Vessel of Lungmen Nuclear Power Plant, we can know that the location of the maximum radial displacement is at about elevation position 2500 and the location of the maximum axial displacement is at the top slab inside in east-west direction. When internal pressure is the designed pressure, the structural behavior is still in linear elastic stage, and the temperature has a significant influence on ultimate pressure strength of containment vessel. In addition, the nature frequency of containment vessel is higher than other common RC buildings.
