  1. introduction • ABWRmodel

  2. 上周問題 • 1.discharge coeffcient? • 2.junction 15 面積? 內徑0.200ｍ，長度2.0ｍ，面積 0.0314 m2 Passive Flooder 內徑0.1 m，長度1.7m，面積 0.0785 m2 COPS 內徑0.203 m (8 in)，長度2 m，面積0.0324 m2

  3. 結果與討論 • Fukushimacase

  4. 主系統壓力 爐心溫度 SRV opened Relocation COPS opened RPV failed

  5. 爐心水位 爐心底部水位

  6. 乾井壓力 抑壓池壓力 COPS Opened

  7. 乾井氣體溫度 下乾井氫氣濃度 PF opened

  8. 上乾井氫氣濃度 抑壓池氫氣濃度

  9. 結果與討論 • Fukushimacase junction 15 = 0.62e5 pa junction 16 = 1.013 e4 pa

  10. 水蒸氣與金屬作用及氫氣濃度之關係

  11. 水蒸氣-空氣-氫氣混合物之燃燒與爆炸條件
