During the last years CIEMAT has been leading the activities in the European Program to develop an integral breeding blanket with advanced performances to work in a realistic DEMO scenario. This blanket is the dual coolant lithium lead (DCLL) working at a limited temperature in order to allow the use of conventional materials and technologies. The design of this blanket was finished, including the definition of the tritium extraction system and tritium simulations. Then, determined by the selection of other two concepts as driver blankets for DEMO, the focus was put on developing a novel BB still based on the DCLL concept but working at higher temperatures, thus increasing the plant net efficiency. In this work, a summary of the status of the DCLL is presented, together with some ideas for developing an advanced high temperature DCLL in the near future.

この数年間、CIEMATは、現実的なDEMOシナリオで動作する高性能の統合増殖ブランケットを開発するための欧州プログラムにおける活動を主導してきた。このブランケットは、従来材料と技術の使用を可能にするために限られた温度で動作する二重冷却材リチウム鉛(DCLL)である。このブランケットの設計は、トリチウム抽出システムの定義とトリチウムシミュレーションを含めて完了した。その後、DEMOのドライバーブランケットとして他の2つの概念が選択されたことにより、焦点は、依然としてDCLL概念に基づくが、より高温で動作し、それによってプラントの正味効率を向上させる新規BBの開発に置かれた。本稿では、DCLLの現状の概要とともに、近い将来に先進的な高温DCLLを開発するためのいくつかのアイデアを提示する。
