The International Research Institute for Nuclear Decommissioning (IRID) carried out the experiments using a 20-meter wide, 12-meter high model of the No. 2 reactor's suppression chamber and torus room -- areas located below the reactor's containment vessel. IRID was established in 2013 by nuclear plant makers, power firms and government organizations to develop technology needed for the decommissioning of the Fukushima plant, which was damaged by the March 3, 2011 earthquake and tsunami. After the disaster, three of the plant's reactors suffered meltdowns in the world's most severe nuclear crisis since the 1986 Chernobyl disaster. The model is located at the Naraha Remote Technology Development Center, near the crippled Fukushima No. 1 plant. "We would like to continue testing until next summer, approximately, and use (the outcomes) in deciding methods to retrieve fuel debris," Atsufumi Yoshizawa, IRID executive director, said.
