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を用いて解析評価した。その結果、冷却材の流路が確保されている限り、冷却材ナトリウム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 capability of natural circulation for core cooling has been evaluated in detail for a station blackout (SBO) event induced by an earthquake and a subsequent tsunami hit. The evaluation was prompted by the accident at the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Company. The plant dynamics computer code Super-COPD was used for the evaluation, which has been validated by analyses of preliminary test results on the natural circulation in Monju. As a result, it was concluded that natural circulation of the sodium coolant will enable the decay heat from the core to be removed under such an SBO condition.
