Fusion Science and Technology 56 巻 ( 2 ) 頁： 861-866 2009年

担当区分：筆頭著者記述言語：英語掲載種別：研究論文（学術雑誌）

The research for the performance improvement of the Liquid Phase Chemical Exchange (LPCE) column has been carried out at Nagoya University in collaboration with National Institute for Fusion Science (NIFS) and Tritium Laboratory Karlsruhe (TLK). Kogel catalysts and Dixon gauze rings were mixed at a certain ratio and packed in the column in a random manner. Performance tests of tritium separation by the column using tritiated water of 26 kBq/cm3 in the electrolyzer were performed at the TLK experimental facility. An effect of axial mixing on the separative performance of the column was examined by a stage-wise model, named Channeling stage model. It was suggested by the analyses that quite a long-distance axial mixing generated in the water phase.

The research for the performance improvement of the Liquid Phase Chemical Exchange (LPCE) column has been carried out at Nagoya University with the collaboration of National Institute for Fusion Science (NIFS) and Tritium Laboratory Karlsruhe (TLK). Kogel catalysts and Dixon gauze rings were mixed at a certain ratio and packed in the column homogeneously. A stage-wise model, named Channeling stage model, was also developed to predict separative performances of the column. In order to design a LPCE column to be tested at the TLK experimental facility we examined the effect of the catalyst packed ratio and the gas-liquid ratio on the separative performance of the column. The optimal value of the catalyst packed ratio was obtained to 30 %. The specifications of the column and the operating conditions of the equipment were reported.

Effects of the gas-liquid ratio on the optimum catalyst quantity for the CECE process with a homogeneously packed LPCE column 査読有り

The effect of the gas-liquid ratio (G/L) on the optimal quantity of the catalyst was studied experimentally in a homogeneously packed bed used for a Combined Electrolysis Catalytic Exchange (CECE) process for hydrogen isotope separation. When the value of G/L was 1.7 total separation factors were relatively small and the optimal quantity of the catalyst could not be found. On the other hand, when the values of G/L were 0.9 and 0.7 the values of total separation factors have maximums and the optimal quantities of the catalyst were clearly obtained.

核融合炉トリチウム水処理システムの研究開発動向

プラズマ・核融合学会誌 83 巻 ( 6 ) 頁： 545-559 2007年6月

記述言語：日本語

核融合炉施設は核融合を起こす燃料として，放射性物質であるトリチウムガスおよび副次的に生じる高濃度トリチウム水を大量に取り扱う施設であり，施設内に設ける燃料循環システムにて処理を行い，燃料サイクルを施設内に閉じてしまうことが必要となる。したがって，核融合炉の安全確保と燃料サイクルの確立を目指す上で，トリチウム水の処理は鍵となる技術である。本報では，ITERにおけるトリチウム水処理システムの開発経緯，第一壁冷却水やブランケット冷却水の処理までを見通した核融合原型炉に向けた水処理総合システムの研究開発状況を紹介する。

Isotope separation experiments of hydrogen and deuterium are performed with two types of packed beds filled with Kogel catalysts (4.0-6.7 mm spherical, 0.8 wt% Pt deposited) and Dixon gauze rings (6 mm outer diameter, 6 mm height). One is the layered bed where layers of Kogel catalysts and that of Dixon gauze rings are filled in the column alternately. The other is the homogeneous bed where Kogel catalysts and Dixon gauze rings are mixed and filled in the column homogeneously. The separative performance of the homogeneous bed is appreciably greater than that of the layered bed, where the quantities of the catalysts are equal for both beds.
