Abstract

　原子炉において、入口ノズル（４４）及び出口ノズル（４５）を有する原子炉容器（４１）内に炉心槽（４６）を配置し、この炉心槽（４６）内に炉心（５３）を配置する一方、原子炉容器（４１）と炉心槽（４６）の底部により下部プレナム（５８）を区画すると共に、原子炉容器（４１）と炉心槽（４６）の側壁によりダウンカマー部（５９）を区画し、下部プレナム（５８）にリング形状をなす上部リング（６５）及び下部リング（６９）とこの各リング（６５，６９）の内側に放射状をなす複数のスポーク（６４，６８）からなる整流部材（６１）を設けることで、圧力容器内に導入された冷却材を下部プレナムから炉心に対して径方向及び周方向に均一に供給することで熱交換効率の向上を図る。
