本検討では、FBRサイクル実用化戦略調査研究のフェーズIIの2年度として、昨年実施した脱硝転換工程に引き続き、低除染ペレット製造プラントのペレット成型から燃料要素組立前半までの各設備について、遠隔自動化を考慮した機器設計、ライン構成、セル内配置設計を行い、下記の成果を得た。(1)遠隔自動運転を基本とした各設備の概略構造設計およびプロセスの概念設計を行い技術的成立性を確認した。(2)トラブル時、ユニットを保守エリアまで搬送し補修する保守システムの成立性を確認した。(3)各設備の機器の故障に関する情報を検討し、プラント特性シミュレータを用いて工程毎の処理能力およびバッファ容量をパラメータに稼働率を評価した。(4)建屋内配置図について、フェーズIの配置計画を基本に、各設備の設計進捗結果を反映した見直しを行い、精度を高めた。

As 2nd fiscal year of phase II of FBR cycle utilization strategy investigation research, following on the denitration conversion process 1ast year, the apparatus design in consideration of remote automation, line composition, and the arrangement design in a cell were performed, and the following result was obtained in this examination about each equipment from pelletizing process to former part of fuel element assembling process of a low decontamination pellet manufacture plant. (1)The outline structure design of each equipment based on remote automatic operation and the conceptual design of a process were performed, and technical formation nature was checked. (2)The formation nature of a maintenance system which conveys the units to maintenance area and repairs was checked at the time of a trouble. (3)The information about failure of the units of each equipment was examined, and operating ratio was evaluated using the plant characteristic simulator which took the throughput and buffer capacity for every process as parameters. (4)About the arrangement plan of equipments in a building, reexamination the arrangement plan of phase I by reflecting the design progress result of each equipment was performed, and accuracy was raised.
