Abstract

 

The Great East Japan Earthquake on March 11, 2011 generated a series of large tsunami that resulted serious damage to the Fukushima Daiichi Nuclear Power Plant (FDNPP) and radioactive substances were discharged inside buildings of the FDNPP and to the environment. We are now developing remote radiation monitoring methods in high dose-rate fields in the buildings, besides the contaminated environment. In these measurements, we need evaluation technology of 2D/3D distribution of radioactivity in and around the buildings of the FDNPP. Furthermore, it is necessary that radiation-hard detectors that can measure remotely the shapes and nuclide distributions of residual debris inside the reactor pressure vessel and primary containment vessel. In this presentation, I will talk our research and development on this subject.

 

 

CV

 

Dr. Tatsuo Torii, Head of the Remote System and Sensing Technology Division, Collaborative Laboratories for Advanced Decommissioning Science (CLADS), Japan Atomic Energy Agency (JAEA). He is a researcher of radiation measurement and atmospheric electricity. He has engaged in research on environmental radiation and radiation measurement. So far, he has researched generation mechanism of energetic radiation in thunderclouds and has been doing R&D of the advanced radiation detectors. After the accident in Fukushima Daiichi nuclear power plant in 2011, aerial monitoring and the R&D of remote sensing technology, such as using autonomous unmanned aerial systems, were carried out. Doctor of Engineering (Osaka Univ.)
