Naraha Remote Technology Development Center is open for various users to contribute to recovery of the coast area of Fukushima as well as the decommissioning of Fukushima Daiichi Nuclear Power Station. The center is located within a distance of 20 km from the Fukushima Daiichi station. This is the first development center funded by the Government near the Fukushima Daiichi. Many people expect that the center plays a significant role to contribute to the decommissioning of Fukushima Daiichi and recovery of Fukushima area from the hazards. The author describe details of the facility and our plan.

Japan Atomic Energy Agency (JAEA) is developing robot technologies and laser technologies, also is developing fusion technologies of robot and laser in Naraha Remote Technology Development Center. In addition to robot control technology based on measured results by laser sensing, JAEA is now developing laser technology for soundness check of concrete structure like as buildings of nuclear facilities.

In August 2015, we ran an educational program about laser technologies in Tsuruga district of Fukui prefecture and did the other about robot technologies in Tokai of Ibaraki separately. After the establishment of the Naraha remote Technology Development Center, a more advanced educational program was arranged in September 2016. It was a 10 days internship program where we focused the sensing techniques with robotic technologies. We are fighting the problems to break through the present miserable situation of Fukushima Daiichi NPPS. Countermeasure technique against water leakage for the suppression chamber is most needed. As a means of eventually sealing down, UV activating polymerization is under testing. Remote sensing for the pedestal concrete strength is also indispensable. Laser ablation technique for ICP-MS is now under preparation. And the facility has been opened for user's R&D at a low price.

For decommissioning of the Fukushima Daiichi Nuclear Power Station, installation of an optical fiber seismic vibrometer using a specially designed robotic system was demonstrated. A water tank with 4.5m diameter and5m depth was used as a demo plant of tank type critical assembly. Micro earthquake response of a water tank was detected by the optical fiber seismic vibrometer. Vibration characteristic of the window of the water tank was monitored by laser Doppler interferometer.
