Abstract:	配合TRR-II爐體改善研究計畫，對反應器爐體結構內部之實驗設施及D2O Tank內燃料組件和控制棒，受流體流動作用影響，進而產生流沖振動的可能性進行研究。本研究針對爐體內之流動、實驗設施、燃料組件和控制棒特性，找出可能產生流沖振動基本要素。我們將使用有限元素法，以數值模擬方式求解TRR-II爐體內流體流動情形，分別求出流體流經實驗設備及D2O Tank內燃料組件和控制棒的流場及壓力分佈，並以這些資料作為振動分析輸入資料，再以振動模式進行流沖振動分析，配合已知相關文獻成果，歸納找出適合的設計規範及條件，以供設計者規劃置放實驗設備及D2O Tank內燃料組件及控制棒的參考過濾準。The possibility of the flow-induced vibration of the test facilities placed inside the TRR-II reactor core and the fuel elements and control rods in the D2O tank is investigated by the present study. According to the flow conditions inside the reactor, the position of the test facilities, and the geometry of the fuel elements and the control rods, we will find out the basic elements of the flow-induced vibration. The flow field inside the reactor will be solved by the finite-element method. The velocity and pressure distributions around the test facilities and the fuel elements will be used as an input information for the vibration analysis. We will find out the screen criterion from the present results together with the previous results. 研究期間：9002 ~ 9012
