福島第一原子力発電所事故の教訓を踏まえ地震・津波による全動力電源喪失等の重大事故を想定し、東海再処理施設における高放射性廃液、プルトニウム溶液等の崩壊熱除去、水素掃気対策について、安全確保の考え方及び具体的対策を整理した。また、安全対策の妥当性を検証するとともに、安全評価に用いたデータの検証の一例を示した。

It was based on teachings of the Fukushima Daiichi Nuclear Power Plant accident, and the view and concrete measure against security were arranged supposing major accidents, such as all the power supply loss by the earthquake and tsunami, about decay heat removal, such as highly radioactivity waste fluid in the Tokai reprocessing facility, and plutonium solution, and the measure against hydrogen exhaust gas. Moreover, while verifying the validity of safety measures, an example of verification of the data used for safety evaluation was shown.
