Abstract

　現時点以降におけるキセノン振動を予測する。このため、原子炉の出力分布の軸方向出力偏差をＡＯｐ、キセノン分布に基づく出力分布の軸方向出力偏差をＡＯｘ、ヨウ素分布に基づく出力分布の軸方向出力偏差をＡＯｉとして、パラメータＤＡＯｐｘ（＝ＡＯｐ－ＡＯｘ）及びパラメータＤＡＯｉｘ（＝ＡＯｉ－ＡＯｘ）を、キセノン振動の角周波数を用いた三角関数の関係式で記述する。次に、前記パラメータＤＡＯｐｘ、ＤＡＯｉｘの初期値に対する位相を求める（ステップＳ１０１）。そして、求めた位相、及びこの位相から求めた前記関係式の係数を用いて表される前記パラメータＤＡＯｐｘをＸ座標に、前記パラメータＤＡＯｉｘをＹ座標にする。これによって得られた軌跡を用いて現時点以降の軌跡を予測し（ステップＳ１０２）、キセノン振動を消滅させるタイミングを予測する（ステップＳ１０３）。
