The Chalk River Tritium Extraction Plant

W.J. Holtslander, T.E. Harrison, D.A. Spagnolo1990年Fusion Engineering and DesignIF 1.7出版社

AbstractThe Chalk River Tritium Extraction Plant for removal of tritium from heavy water is described. Tritium is present in the heavy water from research reactors in the form of DTO at a concentration in the range of 1–35 Ci/kg. It is removed by a combination of catalytic exchange to transfer the tritium from DTO to DT, followed by cryogenic distillation to separate and concentrate the tritium to T2. The tritium product is reacted with titanium and packaged for transportation and storage as titanium tritide. The plant processes heavy water at a rate of 25 kg/h and removes 80% of the tritium and 90% of the protium per pass. Catalytic exchange is carried out in the liquid phase using a proprietary wetproofed catalyst. The plant serves two roles in the Canadian fusion program: (1) it produces pure tritium for use in fusion research and development, and (2) it demonstrates on an industrial scale many of the tritium technologies that are common to the tritium systems in fusion reactors.

チョークリバー重水からのトリチウム除去プラントについて説明する。研究用重水炉からの重水中には、トリチウムがDTOの形態で1~35Ci/kgの濃度で存在する。これは、接触交換によりトリチウムをDTOからDTへ移行させ、続いて深冷蒸留によりトリチウムをT2へ分離・濃縮することで除去される。トリチウム生成物はチタンと反応させられ、チタン化物として輸送・貯蔵用に包装される。本プラントは重水を25kg/hの速度で処理し、1回の通過あたりトリチウムの80%とプロチウムの90%を除去する。接触交換は、専用の耐水性触媒を用いて液相で実施される。本プラントはカナダの核融合プログラムにおいて2つの役割を担う:(1)核融合研究開発用の純粋なトリチウムを生産すること、(2)核融合炉のトリチウムシステムに共通する多くのトリチウム技術を工業規模で実証すること。
