核燃料溶液の臨界事故で放射線分解ガスボイドによる激しい出力振動が生じる場合を対象とし、事故発生後の経過時間とその時刻までに添加された反応度などの関数として、核分裂により生じるエネルギーを表す式を、準定常法に基づいて導出した。実験値及び準定常法で得られたデータと比較し、実験値をよく再現することを確認した。

For the criticality accident with intense oscillation in power due to radiolytic gas void in nuclear fuel solution, an equation has been derived based on pseudo-steady state method, by which equation the fission-energy is expressed as a function of elapsed time and inserted reactivity. It has been confirmed that the results obtained by using the equation show better agreement to experimental data than those obtained by pseudo-steady state method.
