D and T mixing imbalance and inhomogeneity in an inertial confinement fusion pellet

S Kawata, K Kurawaki, K Hirota, K Fujita1999年Fusion Engineering and DesignIF 1.7出版社

AbstractThis paper shows that a 20% initial mixing inhomogeneity of deuterium (D) and tritium (T) fuels and also a 30% T reduction in a D-T pellet still give a sufficient fusion energy output in D-T inertial confinement fusion (ICF). One and two dimensional numerical simulations and estimation studies support these results. The results mean that fusion energy output and burn process are rather insensitive to the significant T reduction and to the initial inhomogeneous fuel mixing in the D-T ICF pellet.

本論文は、重水素(D)とトリチウム(T)燃料の20%の初期混合不均一性、およびD-Tペレットにおける30%のT削減があっても、慣性核融合(ICF)において十分な核融合エネルギー出力が得られることを示す。一次元および二次元の数値シミュレーションと推定研究がこれらの結果を裏付けている。これらの結果は、核融合エネルギー出力と燃焼過程が、Tの大幅な削減およびICFペレット内の初期の不均一な燃料混合に対してかなり鈍感であることを意味する。
