プラント解体作業支援のための現場再構成モデルを用いた情報参照システムの開発

Abstract

There are many nuclear power plants(NPPs) which are approaching their operational lifespan. The need to dismantle NPPs is increasing. By using AR, workers can understand the information related to dismantling work intuitively. 3D reconstruction models of dismantle fields make it possible for workers to observe circumstances of dismantling fields without visiting the fields. In this study, an information reference system based on AR and 3D reconstruction models has been developed and evaluated. The evaluation consists of interview and questionnaire survey with 6 workers at NPP, who used this system along with a scenario. The results showed that it may be possible to reduce the time spent and mistakes in decommissioning fields. The results also showed that it is easy to refer information in dismantling fields. However, it was also found that it is difficult for workers to build reconstruction models of dismantling fields by themselves.
