高温ガス炉に従来のB$$_{4}$$C制御棒に代わりLi制御棒を利用する場合について、制御棒反応度価値とトリチウム生成量の燃焼変化を、連続エネルギーモンテカルロ燃焼計算コードMVP-BURNを用いた炉心計算を行って調べた。炉心外側にLi制御棒を装荷することで、余剰反応度を適切に抑えるとともに、トリチウム生産性能を従来の検討結果に比べて20%程度増加させることができた。

Changes in a control rod value and a production amount of tritium with burnup were examined with a continuous energy Monte Carlo code MVP-BURN for a high temperature gas cooled reactor in which B$$_{4}$$C control rods were replaced with Li control rods. It was shown that the amount of tritium production was increased about 20% from the previous study and the excess reactivity was properly controlled by installing the Li control rods into the outer region of the core.
