Description
本発明は、冷却材喪失事故時に、触媒式水素の再結合により原子炉内の閉じ込め器内の水素を受動的に除去する、改良されたシステムに関する。
従来の水冷却式原子炉は、冷却材喪失事故(「LOCA」)による閉じ込めの完全性に対する脅威を最少限にするように設計されている。LOCAは2つの異なる問題を生じさせ得る。第一に、原子炉の冷却材回路の破損は、熱湯と蒸気との、閉じ込め雰囲気への噴出につながる。閉じ込め器から熱を除去するシステムが採用されない限り、閉じ込め器内の圧力および温度は閉じ込め器の設計限度を超えて上昇し得る。第二に、冷却材の喪失だけでなく緊急冷却材の冷却システムへの注入の失敗を含む深刻なLOCAにおいて、結果として起こる燃料温度上昇は、主要システム内の残留蒸気と、燃料シージング内のジルコニウムとの間の高温反応につながる。深刻な場合には、燃料シージングの完全な酸化が起こり得る。反応は発熱を伴い、水素を生成する。反応により生成された水素は、蒸気と共に主要システムの破損箇所から閉じ込め雰囲気に逃れる。深刻な事故においては、水素の質量放出比率は1秒当たり1キログラムのオーダーであり得る。水素濃度を自己発火限度未満に保つシステムが採用されない限り、潜在的に爆発性のガス混合物が、原子炉内の閉じ込め器内で生成され得る。
本発明の一局面によると、閉じ込め壁内に、原子炉コアおよび該原子炉コアと関連する冷却材ラインを有する水冷却式原子炉における、該冷却材ラインの破損により引き起こされる冷却材喪失事故において生成される水素を、閉じ込め雰囲気から除去するシステムであって、対流の交換における上昇気流路と下流気流路とを該閉じ込め器内に確立する手段であって、該上昇気流路は該冷却材ラインの領域に設けられ且つ該破損箇所からの水素を運ぶために有効であり、該下降気流路は該閉じ込め壁に隣接する領域にある、手段と、該上昇気流路を該冷却材ラインの下流にダクトで送り、該運ばれた水素を該ダクトで送られた上昇気流路に有効に閉じ込める手段と、該運ばれた水素を該ダクトで送られた上昇気流内の酸素と再結合する、該ダクトで送られた上昇気流路内に設けられた触媒式水素再結合装置とを含むシステムが提供される。
図1に、本発明を広い概念で表現した模式図を示す。概して参照符号10で示される原子炉ビルディングは、閉じ込め壁12を含む。外壁14は閉じ込め壁12を囲み、最上部16と最下部18とで開放され、自然対流力により外部の冷却空気が流れ込み得る外部環状領域20を提供する。閉じ込め壁12は鋼鉄または他の熱伝導性金属で形成され得、他方外壁14は典型的にはコンクリートで形成される。鋼鉄およびコンクリートによる構造を図1に示すが、本発明は他の原子炉の設計と関連して使用され得る。
冷却材喪失事故の場合に、触媒式水素再結合を用いて原子炉内の閉じ込め器内部の水素を受動的に除去する、改良されたシステム。閉じ込め器内に設けられたバッフル壁(26)は、対流の交換により閉じ込め器内に上昇気流路と下降気流路とを確立するために用いられる。上昇気流は、冷却材の領域(22)を通過して、破損箇所から水素を運ぶために有効であり、下降気流路は、閉じ込め壁(12)に隣接する領域(28)内にある。冷却材ラインの下流にある上昇気流路はダクトで送られて、運ばれた水素をダクトで送られた上昇気流路に閉じ込める。触媒式水素再結合装置は、上記運ばれた水素と上記ダクトで送られた上昇気流中の酸素を再結合するために、ダクトで送られた上昇気流路内に設けられている。
