東京電力福島第一原子力発電所事故を踏まえ、地震・津波により「もんじゅ」が全交流電源喪失(SBO)となった場合の冷却材ナトリウム自然循環による炉心冷却性について、「もんじゅ」ナトリウム自然循環予備試験結果等により解析の妥当性を確認したプラント動特性解析コード(Super-COPD)を用いて解析した。その結果、冷却材の流路が確保されている限り冷却材の自然循環によって炉心が冷却できることを明らかにした。

The core cooling capability by natural circulations at a station black-out event, induced by an earthquake and a subsequent tsunami attack, has been evaluated in detail, referring to the accident of the Fukushima Dai-ichi Nuclear Power Station of Tokyo Electric Power Company. The plant dynamics computer code: Super-COPD has been used for the evaluation, which has been verified by the analyses of the preliminary test results on the natural circulation in Monju. As a result it was concluded that the natural circulations of the coolant sodium will enable the decay heat removal of the core as far as the sodium coolant flow circuits are intact and secured.
