本文比较测定了2LiF + BeF_2混合熔盐Flibe在Ar-H_2（10%）和Ar气吹扫两种不同条件下，在恒温和线性升温条件下中子辐照后的氚释放率。根据氚在Flibe中的扩散和表面上的T原子与气体组分中的H原子之间的同位素交换，分析了氚释放的实验速率。从Flibe释放的气体具有取决于Ar-H2或Ar吹扫气体的不同条件的HT与TF的不同比率的组成。在Ar-H_2吹扫和300°C条件下，中子辐照后Flibe释放的氚主要是HT。该模型能较好地模拟氩氢吹扫条件下氚的释放速率。在Ar吹扫条件下，虽然其释放后的化学形式为TF，但通过与金属表面的相互作用，其部分转变为HT。
Abstract The rate of tritium released from temperature-controlled Flibe (a mixed molten salt of 2LiF + BeF2) after neutron irradiation was determined comparatively under two different conditions of Ar-H2 (10%) or Ar gas purge at a constant or linearly elevated temperature. Experimental rates of tritium release were analyzed based on its diffusion in Flibe and isotopic exchange between T atoms on surfaces and H atoms included in gaseous components. Gas released from Flibe had compositions of various ratios of HT to TF depending on the different conditions of Ar-H2 or Ar purge gas. The major molecular species of tritium released from Flibe after neutron irradiation was HT under the condition of the Ar-H2 purge and 300°C. The rate of tritium release under the Ar-H2 purge was simulated well by the present analytical model. Although its chemical form immediately after the release was TF under the condition of Ar purge, it was changed to HT partly by interaction with metallic surfaces.
