The edge transport modelling of $1\mathit{GW}$1GW$1\mathit{GW}$ EU-DEMO burning plasma is performed by SOLPS-ITER transport code with kinetic neutrals and full drifts and currents switched on. The efficiency of Ar and Ne as a divertor radiant is compared for such a condition. It is found from simulations that both Ar and Ne are suitable to reduce the target heat loads below $5\mathit{MW}/m^2$5MW/m2$5\mathit{MW}/m^2$, and to achieve similar profiles at the OMP and along targets, however, Ne seeding rate should be 4.5 times bigger than that of Ar. Analysis of impurity transport results in that Ar is better compressed in divertor than Ne. With both radiants up to 70% of power flux to the computational domain is irradiated, core $Z_{\mathit{eff}}$Zeff$Z_{\mathit{eff}}$ does not exceed 2.5, core radiation is negligible (less than 8.5% of income power), neutral deuterium pressure in the private flux region is 20 Pa. However, the electron temperature along targets does not reduce below 15 eV in the far scrape-off layer, which may cause high level of tungsten sputtering.

SOLPS-ITER EU-DEMO 建模与漂移和动力学中性

边缘传输建模$1\mathit{GW}$1GW$1\mathit{GW}$EU-DEMO 燃烧等离子体由 SOLPS-ITER 传输代码执行，具有动力学中性和全漂移和电流开启。在这种情况下，比较了 Ar 和 Ne 作为偏滤器辐射的效率。从模拟中发现，Ar 和 Ne 都适合将目标热负荷降低到以下$5\mathit{兆瓦}/{米}^2$5兆瓦/米2$5\mathit{MW}/m^2$，并且为了在 OMP 和沿目标实现类似的剖面，然而，Ne 播种率应该是 Ar 的 4.5 倍。杂质传输分析结果表明，Ar 在偏滤器中的压缩比 Ne 更好。两个辐射点都有高达 70% 的功率通量被辐射到计算域，核心$Z_{\mathit{效果}}$Z效果$Z_{\mathit{eff}}$不超过 2.5，核心辐射可忽略不计（小于收入功率的 8.5%），私人通量区域中的中性氘压力为 20 Pa。但是，沿目标的电子温度在远刮除中不会降低到 15 eV 以下层，这可能会导致高水平的钨溅射。
