中文摘要 | 本研究是以核能研究所『壓水式反應器比例縮小安全測試設施』(簡稱IIST)模擬 壓水式核電廠發生電廠全黑 (Station Blackout) 事故之實驗數據, 驗證 RELAP5/MOD3.1 熱流分析程式模擬 IIST 全黑事故時,整體系統長期暫態熱流現象之能力及準確性。經由相 互比對 RELAP5/MOD3.1 程式計算值與 IIST 實驗數據結果顯示: (1) 於 IIST 全黑實驗過 程中發生之蒸汽產生器二次側冷卻水燒乾;(2) 喪失蒸汽產生器二次側熱沈造成一次側壓力 上昇; 及 (3) 調壓槽頂端安全釋壓閥開啟使爐心冷卻水流失燃料棒裸露等關鍵性熱流現象 ,皆可從分析程式計算結果中獲得,且上述事件發生的時序與實驗量測值亦相近似。 |
英文摘要 | A station blackout experiment under the loss of all Alternating Current (AC) power source conducted at the INER Integral System Test (IIST) facility was analyzed using the RELAP5/MOD3.1 code. The aim of this work is to assess the capability of the RELAP5/MOD3.1 code for simulating the thermal-hydraulic behavior of the Reactor Coolant System (RCS) during the IIST station blackout transient. It is fund that the calculated results are in good agreement with the experimental data, especially in the aspect of the chronology of the major events, such as (1) steam generator secondary boil-off, (2) RCS pressurization after loss of secondary heat sink, and (3) core uncover resulting from the loss of primry coolant throungh an open pressurized safety valve. |
