摘要

        民國九十八年於台北縣貢寮鄉興建第四核能電廠，透過鈾-235分裂反應產生能量，使水加熱成蒸汽推動發電機發電，無可避免的在核分裂的過程中會產生大量的放射性物質，若核能電廠發生嚴重事故，會使大量放射性物質釋放到外界環境，對環境及民眾造成傷害，近核四廠址80公里的海域內約有70座海底火山，比起日本，台灣核四廠在面對地震風險評估更有其必要性。
        一般在評估核電廠的地震風險會結合機率理論和統計分析，並連結核電廠各系統以組成風險評估路徑，依據階層式的判斷來評估地震對於核電廠的損壞程度，但因龐大且複雜的資料量使工程師在判讀上無法一目了然獲得元件損壞的資訊，故此報告以核電廠各系統之風險評估資料為基礎結合損壞路徑之判斷方式，設計一視覺化界面來呈現核電廠之地震損壞路徑。介面之設計以D3.js為主，透過地震等級的選擇，能展現出不同地震大小對於核電廠之受損路徑圖與風險，以顏色清楚區分系統元件為正常或損壞，色塊大小代表了風險之大小，藉由縮放功能可以反回上一階層或進入下一階層判斷作更細緻的了解，特色是能夠展示出核電廠損壞路徑的全貌，使工程師可以及時針對受損部分來進行查驗，另因D3.js具有跨平台之特性，故研發出之介面可在任何具有網路之平台上作使用，大大增加了使用的方便性。

Abstract

This project is developing a visualization tool for illustrating the risk of a nuclear power plant during different levels of seismic event. We integrated the failure logic tree and the corresponding risk of each components in the tree into one piece. Users are allowed to navigate through 8 different levels of seismic events. A zoomable rectangle grid method is used as a visualized integration outcome. In order to enhance the compatibility of our software, we decide to develop with D3.js under html structure as a web-based software which can be easily deployed to the most of platform. We also optimize the software for mobile devices to raise the mobility and productivity when working in the field. The result shows a great improvement in comprehensibility of the original data. Users can access to the data they need more efficiently and clearly. For future work, the integration of mathematical method behind the risk analysis is needed for equipping the software the ability of automated generation.
