Description
原子炉の一次回路は、小型のシステムである。
分離構造5の遮蔽構成部分のリングは、数が減少するか又は完全に除去されるので、炉心の半径方向の拘束に関して経済性及び機械的強度の点において利点が存在する。
遮蔽構成部分のリングの除去は、交換するべき構成部分の数を減少させ、実施されるべき保守作業を簡単にし、原子炉の停止時間を短縮する。
熱交換器の半径方向の位置決めは、分離構造5の最大寸法により制限されるのではなく、より小さい直径を有する、分離構造5の部分16によってのみ制限される。
熱交換器への供給は、分離構造から半径方向に離れるダクトを必要とせず、既知の解決手段において考えられているように、部分16の上方から行われるのではなく、ポンプ−交換器ユニット21に供給するダクト20の円筒状部分19と接続部分15との間において封止装置18を介して垂直方向において行なわれる。
分離構造5の下側部分14及び接続部分15のローブ形状(lobed shape,丸い突出形状)は、より多くの補助構成部分25が原子炉に設置できるように、原子炉容器2に対して、半径方向への拡張がより小さい下側部分14の部分23と接続部分15との間の幅広い自由な容積24を残す。
分離構造5の下側部分14及び接続部分15のローブ形状と、カバー26の対応するローブ形状とは、原子炉の補助構成部分25を除去することなく、分離構造5を交換することを可能にする。
