对于ITER的等离子体组件，氚(T)通过CuCrZr散热器渗透到冷却剂中会引起T的安全性和回收问题。本文对氢同位素在铜材料中的渗透和滞留进行了实验研究。采用氘(D)气驱渗透（GDP）实验对其渗透率和扩散系数进行了评价。同时，通过气体吸收和随后的热解吸光谱（TDS）比较了这些Cu材料中的D保留性能。最后，证明了D通过Cu及其合金的低能量（几eV）等离子体驱动渗透（PDP）。与GDP相比，D渗透通量显著增强。
For plasma-facing components of ITER, tritium (T) transport into the coolant by permeation through CuCrZr heat sink will raise T safety and recovery issues. In the present work, hydrogen isotope permeation and retention in copper (Cu) materials have been experimentally studied. Deuterium (D) gas-driven permeation (GDP) experiments have been performed to evaluate the permeability and diffusion coefficients. Meanwhile, D retention properties in these Cu materials are compared by gas absorption and subsequent thermal desorption spectroscopy (TDS). Finally, low energy (several eV) plasma-driven permeation (PDP) of D through Cu and its alloys has been demonstrated. Significant enhancement in D permeation flux compared with that of GDP has been measured.
