老朽化し、補修対応が困難となったアナログカメラシステムの更新として、休止設備である音声通話用通信網等を再活用し、ADSLデータ通信と同種のVDSL技術を利用したデジタル通信システムを考案した。もんじゅ全域において、今後増加する解体作業や機器の運転状態確認等の他の遠隔監視ニーズに対応するカメラの追加設置や、仮設計器の測定データ送信にも低コストで柔軟に対応可能な遠隔監視システムの概要について紹介する。

As a replacement for the analog camera system which has become difficult to repair, a digital transmission system using VDSL technology was devised by reusing idle facilities such as the voice communication network. This paper presents an overview of the remote monitoring system that can flexibly respond to the installation of additional cameras for other remote monitoring needs such as decommissioning work and equipment operation status checks that will increase in the future MONJU, as well as the transmission of measurement data from temporary instruments at a low cost.
