Visit to the Japan Atomic Energy Agency (JAEA) Naraha Center for Remote Control Technology Development and Fukushima Daiichi NPS
On Friday, August 2, 2019, the IRID organized a site tour of the Fukushima Daiichi NPS and the JAEA Naraha Remote Technology Development Center for students who gave presentations and exhibited posters at the IRID Symposium 2019. They included undergraduates, graduate students, and students at the National Institute of Technology. The site tour is arranged yearly on the day after the symposium. This site tour also included the TEPCO Decommissioning Archive Center, which was newly opened in November 2018.
This site tour intended to promote a better understanding of R&D related to the decommissioning among those students who are expected to work on the decommissioning in the future. The site tour also aimed to provide an opportunity to visit the Fukushima Daiichi NPS and the Naraha Remote Technology Development Center to be utilized for further research activities.
