Abstract
【解決手段】低圧及び高圧でも原子炉系統に非常炉心冷却水の注入が可能にする。低圧の窒素が充填され非常炉心冷却水が収容されて、原子炉容器に非常冷却水注入管によって連結された安全注入タンクと、高圧水蒸気が収容されて、前記高圧水蒸気が排出される安全弁管が装着された加圧器及び高圧の前記加圧器と低圧の前記安全注入タンクが圧力平衡になるように、前記安全注入タンクの上部と前記加圧器の上部を連結して選択的に開閉される圧力平衡管を含む。原子炉系統が加圧される事故時には、前記非常炉心冷却水が高圧の前記原子炉容器に注入可能になるように、前記圧力平衡管の開放によって前記安全注入タンクが低圧から高圧に変更されるように構成する。また、電源完全喪失事故時にも、バッテリー供給非常電源によって駆動する弁を適用して高圧の安全注入タンクによる非常炉心冷却水注入が可能である。
