中国氦冷固态TBM对ITER环向场线圈能量沉积的影响

Influence research on energy deposition in TFC of CN HCCB TBM for ITER

基于国际热核实验堆(ITER)的Alite模型和中国氦冷固态陶瓷试验包层模块(CN HCCB TBM),对装载了CN HCCB TBM后ITER装置的环向场线圈(TFC)的能量沉积的分布和CN HCCB TBM对能量沉积的影响进行了计算分析。结果表明,放入CN HCCB TBM会使TFC能量沉积减小了3%左右,不会使TFC能量沉积情况恶化;TFC能量沉积主要位于内侧的14个扇区,TFC包壳和超导材料的功率密度的最大值低于限值,满足要求。

Based on Alite model of ITER and CN HCCB TBM, research of influence on the energy deposition of TFC caused by CN HCCB TBM is carried out. The calculation is carried out by MCNP code, and a mesh-based weight window is used to reduce variance. The analysis indicates that installing CN HCCB TBM could reduce the energy deposition in TFC by 3%; most of the energy deposition is local in the 1-14 sectors of inner-side; the power density peak is located in the ninth sector and the required limits satisfied.
