NRA Approves Decommissioning Plans for Kansai EP’s Ohi-1 and-2

At a regular meeting on December 11, the Nuclear Regulation Authority of Japan (NRA) approved decommissioning plans for the Ohi-1 and -2 Nuclear Power Plants (NPPs, PWRs, 1,175MW each), owned and operated by the Kansai Electric Power Co., Inc. (Kansai EP). Having accepted applications from the power utility in November 2018, the NRA decided to open its examinations of the decommissioning plans to the public from the viewpoint of ensuring transparency, just as it does for compatibility examinations under the new regulatory standards. It has already carried out five public examinations since December 2018, asking the operator for explanations. Among other things, the NRA found that internal standards, systems and the like are sufficient to ensure that decommissioning work would not aff...more

JAEA Holds International Forum on Peaceful Use of Nuclear Energy, Nuclear Non-Proliferation and Nuclear Security

On December 4, the International Forum on Peaceful Use of Nuclear Energy, Nuclear Non-Proliferation and Nuclear Security, sponsored by the Japan Atomic Energy Agency (JAEA), was held in Tokyo. Through two panel discussions with domestic and overseas experts, specialists and governmental personnel, participants discussed future challenges and countermeasures in the areas of nonproliferation and security. According to the Japan Atomic Energy Commission’s report of September 2011, nuclear security is defined as “prevention, detection and response to any criminal or other intentional act against nuclear or other radioactive materials, or their related facilities or activities, including their transport.” Since the 9-11 terrorist attacks in the United States in 2001, people have been increas...more

NRA Issues Draft Review Report: Onagawa-2 Meets New Regulatory Standards

On November 27, the Nuclear Regulation Authority (NRA) of Japan issued a draft review report on its examination of the Onagawa-2 (BWR, 825MW), owned and operated by the Tohoku Electric Power Co., for compatibility with the new regulatory standards. The report will be officially finalized after being referred to the Japan Atomic Energy Commission (JAEC) and the Ministry of Economy, Trade and Industry (METI), and is opened to the public for comments. An application to the NRA for a compatibility examination of Onagawa-2 was filed in December 2013. Based on geological characteristics, as well as the fact that the Onagawa-2 unit had experienced a major earthquake, the NRA carried out its examination cautiously, especially vis-à-vis the evaluation of geological features, seismic motion an...more

RIKEN Unveils Transportable Compact Neutron Source System

On November 26, Japan’s RIKEN made a demonstration of its RIKEN Accelerator-Driven Compact Neutron Source System (RANS-II) to the press. The system will be used in a wide range of areas, including the diagnosis of the deterioration of concrete infrastructure and the analysis of raw materials and products at factories. Currently, neutron sources used for industrial purposes include the Japan Proton Accelerator Research Center (J-PARC) and the Japan Research Reactor No. 3 (JRR-3). In cooperation with industry, RIKEN has been working to develop a transportable neutron source system. In 2013, it succeeded in visualizing internal steel corrosion nondestructively using a compact neutron-driven system (RANS). Later, in 2016, it developed technology to see internal damage in concrete, and two y...more
