NEL provides support for the safer operation of nuclear power plants in Japan by keeping our eyes on the world and incorporating the latest technologies and knowledge.
State-of-the-art technologies continue to advance day by day. In order to provide comprehensive support for nuclear power plants, it is essential to gather information with a broad perspective. In order to keep abreast of the latest technological trends, we have information sources around the world and actively interact with them. We exchange information with overseas organizations on a regular basis, participate in international conferences and symposia, and propose to domestic electric utilities the technical information we have obtained and how to utilize it. We also offer high value-added services, such as capturing superior world-class technologies through overseas exchanges and developing our own technologies.
Examination and formulation of codes/standards
With our extensive experience in Japan and the latest technology and information from overseas, we are involved in the study and formulation of codes and standards. We are also actively involved in establishing rules for education and training in various fields related to nuclear power plants, based on our experience in developing codes/standards.
Non-Destructive Examination (NDE)
While incorporating the latest knowledge from overseas, we are contributing to the reliable inspection of nuclear power plants by supporting the development of the standards for Performance Demonstration of Ultrasonic Testing Systems, one of the qualification methods for nondestructive examination (NDE), training guidelines for ultrasonic inspectors, Japan Electric Association Codes and Guidelines for ultrasonic testing and eddy current testing, and Japan Society of Mechanical Engineers Standards for in-service inspection of nuclear power plants.
Plant Life Management
We are contributing to the establishment of the standard by serving as the organizer of the subcommittee of the Atomic Energy Society of Japan (AESJ) in the formulation of the "Implementation Standard for Aging Management for Nuclear Power Plants," which is used as a reference for nuclear operators in performing ageing management technical evaluation of their nuclear power plants. The "Summary Sheet of Ageing Phenomena” developed as part of the development of the AESJ Standard will serve as the guide for maintenance activities at all nuclear power plants, and is the culmination of our plant life management work.
Probabilistic Risk Assessment
We conduct probabilistic risk assessments (PRAs), which are effective in quantitatively identifying the characteristics and vulnerabilities of nuclear facilities, and utilize risk information, including information obtained from PRAs. In addition, we are greatly contributing to the formulation of the AESJ PRA standards (at power, shutdown, external event (earthquakes and tsunamis) PRA, etc.), which are used as a reference in preparing an application for the review of plant safety improvement measures, as a member of the AESJ Standards Committee.
Fuel Management/Core Physics
We are contributing to the high reliability of nuclear safety by supporting the formulation of safe and effective Japan Electric Association Codes and Guidelines for the inspection and management of fuel and core, which are the key elements of nuclear power generation, while incorporating the latest knowledge at home and abroad.
Decommissioning
In order to promote the optimized decommissioning of nuclear reactor facilities, which are expected to increase in the future, we are involved with the formulation of the Atomic Energy Society of Japan Standards related to decommissioning. We participate in the Decommissioning Subcommittee and work with the Subcommittee members to achieve the optimized implementation of decommissioning based on our reliable knowledge building on our business experience in safety assessment and residual radioactivity survey.

Activities
Collaboration with the IAEA for Educational Program
On February 10, 2016, NEL donated our training core simulator, Micro-Physics Simulator TM Lite Edition, to the IAEA at the IAEA headquarters in Austria. This donation is intended to contribute to the global development of nuclear education/training through collaboration between NEL and IAEA.
The license agreement for this donation was signed at the IAEA headquarters in Austria, and the contents of the license agreement are posted on the IAEA website. The IAEA maintains a wide range of training simulators, and NEL simulator has been added to this collection of training simulators. The IAEA maintains a variety of training simulators, and this simulator has been added to this collection. The IAEA collection of training simulators, including NEL simulator, are available to nuclear organizations in the world free of charge. Human resource development in the nuclear field is an important theme for any country. Personnel involved in nuclear energy need to have knowledge in various fields (physics, thermal-hydraulics, materials, etc.), and efficient education is required to acquire this knowledge. It is expected that education/training utilizing simulators, which faithfully simulate the behavior of an actual nuclear power plant, can bring about high educational effects. NEL has been working on the development of training simulators, and has delivered the Micro-Physics Simulator TM (paid version), which is an enhanced version of the simulator, to the educational institutions and nuclear related organizations in Japan and overseas, and the Micro-Physics Simulator TM has been highly evaluated. In addition, NEL offers comprehensive nuclear training services, including the development of educational materials for simulator training and the dispatch of training instructors for giving the lecture.
