摘要：
Hydrogen Inventory Simulations for Plasma facing components (HISP) 是一个开源的模拟工具，用于建模磁约束聚变装置中等离子体面对组件（PFCs）中氢同位素库存的演变。其目标是通过演示研究描述在ITER中氚（T）去除策略的效率。HISP将等离子体代码的输出转换为沿ITER第一壁（FW）和分离器的时空平均输入，使用FESTIM进行1D H传输模型。测试了三种场景，包括DT操作和不同T去除方法。通常，DT操作在10天的DT脉冲后会使FW和分离器组件中的T总量约为35克。几乎80%的总T库存存在于分离器中的共沉积硼层中。烘焙被证明是分离器中最有效的T去除方法，可使钨的T库存减少约88%，硼的T库存减少约30%。T去除还评估了等离子体 glow discharge conditioning（GDC）和低功率氘化物（DD）脉冲。由于烘焙的高去除效率，测试场景中包含GDC和DD脉冲并未显著改变最终的T库存值，这些值在FW和分离器之间变化分别小于2%和10%。
英文摘要：
Hydrogen Inventory Simulations for Plasma facing components (HISP) is an open-source simulation tool to model the evolution of hydrogen (H) isotopes inventory in plasma-facing-components (PFCs) of magnetic confinement fusion devices. The objective was to produce a demonstrative study describing the efficiency of tritium (T) removal strategies in ITER. HISP transforms plasma code outputs to spatial-averaged inputs along ITER's first wall (FW) and divertor for 1D H transport models using FESTIM. Exposure conditions were tested in three scenarios that included DT operation and varied T removal methods. Generally, DT operation resulted in $\approx$ \SI{35}{g} of T in FW and divertor components after 10 days of DT pulses. Almost \SI{80}{\%} of the total T inventory resided in co-deposited boron layers in the divertor. Baking proved to be the most effective T removal method in the divertor, decreasing T inventory by almost \SI{88}{\%} for tungsten and almost \SI{30}{\%} for boron. T removal was also evaluated from Glow Discharge Conditioning (GDC) - with a peak efficiency of \SI{23}{\%} in the tungsten FW - and low power deuterium (DD) pulses - with a peak efficiency of \SI{13}{\%} in the entire divertor. Due to the high removal efficiency of baking, inclusion of GDC and DD pulses in the tested scenarios did not meaningfully change final T inventory values, which varied by less than \SI{2}{\%} in the FW and \SI{10}{\%} in the divertor between scenarios.
