A high porous-matrix 2D-SiCf/SiC as permeator for the efficient recovery of tritium solved in Pb–17Li with compact and efficient columns®

Luis A Sedano2001年Fusion Engineering and DesignIF 1.7出版社

AbstractThe economical recovery of tritium from the breeding materials represents a major issue in the conception of future fusion plants. The satisfactory structural compatibility of Pb–17Li with SiCf/SiC and the large hydrogen rates through it, suggest the use of a high-porosity-matrix (HPM) 2D-SiCf/SiC as permeator membrane for the recovery of tritium dissolved in Pb–17Li. Uncertainties concerning Pb–17Li with SiCf/SiC interaction are identified in order to analyze the main feasibility issues of SiCf/SiC extractors. For a wide range of operating modes the ideal recovery efficiencies of a HPM 2D-SiCf/SiC column are obtained by the numerical implementation of a general dispersion model. The comparison of the obtained efficiencies with those of the actual bubbling columns demonstrates the potential attractiveness of the proposed extractor concept.

トリチウムの経済的回収は、将来の核融合炉の設計における主要な課題である。Pb–17LiとSiCf/SiCの良好な構造的適合性、およびPb–17Liを通る高い水素透過速度は、Pb–17Li中に溶解したトリチウムを回収するための透過膜として、高多孔質マトリックス(HPM)2D-SiCf/SiCの使用を示唆している。SiCf/SiC抽出器の主な実現可能性の問題を分析するために、Pb–17LiとSiCf/SiCの相互作用に関する不確実性が特定されている。広範囲の運転モードに対して、HPM 2D-SiCf/SiCカラムの理想的な回収効率は、一般的な分散モデルの数値的実装によって得られている。得られた効率と実際の気泡塔の効率との比較は、提案された抽出器コンセプトの潜在的な有用性を示している。
