The ISCN of the JAEA provides effective trainings in order to strengthen nuclear security for emerging nuclear power countries in Asia to realize Japan's National Statement at the Washington Nuclear Security Summit in April 2010. As a part of these activities, the ISCN has developed the PPEF and the VR training system, which are training tools to implement experience-oriented and interactive lessons. These two facilities are mutually complemented and contribute to deeper understandings through actual practices in addition to the classroom lesson. The ISCN initiated its full-scale training from 2012 JFY, and these two facilities received more than 450 trainees or vistors from Japan and over-sea countries. This paper provides the basic concepts and outlines of these two facilities and the training programs that use them for teaching the nuclear security.

The Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN), under the Japan Atomic Energy Agency (JAEA), has been doing activities, since its establishment, that contribute to the strengthening of nuclear nonproliferation and nuclear security. ISCN is providing training courses for the purpose of capacity-building assistance through human-resource development. ISCN has a Virtual Reality (VR) System specifically for training in nuclear security. The course is specifically for trainees who have had few experiences in nuclear security. Trainees can see the nuclear physical-protection (PP) system of a nuclear power station in virtual space and learn how it works. ISCN has also been preparing another training course that will be for operators in Central Alarm Stations (CAS). Trainees will be able to brush up their skills through simulation exercises against enforced entry.

Japan is a country far away from Europe and the US. The news of the accident occurred in this country was immediately reached to countries throughout the world and the image of the explosion was repeated on TV screens. This accident aroused various discussions on nuclear policy. The responses of countries divided with the US and France maintaining the stance of promoting nuclear power and Germany and Italy clarifying its policy to withdraw from nuclear energy. This report provides information on the responses to the accident taken by the US and other states.

The 1999 JNC International Forum on the Peaceful Use of Nuclear Energy the Nuclear Fuel Cycle and Nuclear Non-Proliferation Technology, a continuation of the annual International Forum on Nuclear Non-proliferation sponsored by its predecessor organization PNC (Power Reactor and Nuclear Fuel Development Corporation), was held February 22-23, 1999 in Tokyo, Japan. About 380 people from government, industry, and academia involved in nuclear technology and issues attended the forum. A distinguished group of speakers participated in the forum sessions including highly respected technology and policy experts from France, Russia, and the United States. Session themes were: (1) Advanced Nuclear Technology for Peaceful Purposes and Nuclear Non-Proliferation, (2) Transparency Improvements in Nuclear Technology through the Disposition of Excess Nuclear Weapons Plutonium. This document provides a record of speeches and discussion which have no written documentation and summarizes presented papers as appropriate. Full papers prepared by the presenters can be found in The Proceedings of the 1999 JNC International Forum on the Peaceful Use of Nuclear Energy.

The Integrated Support Center for Nuclear nonproliferation and Nuclear Security (ISCN) under the Japan Atomic Energy Agency (JAEA) began the development of Virtual Reality (VR) training system for the purpose of teaching trainees nuclear security. ISCN set up two VR training courses by 2013. One is for teaching a nuclear security system of nuclear plants. The VR training system allows trainees to have virtual experiences visiting a nuclear plant. Through these experiences, trainees are able to learn how physical protection systems work in the plant. The course focuses on learning fundamental knowledge and is suitable for trainees having little experiences in the field of nuclear security. The other is for teaching fundamental skills corresponding to a contingency plan in a Central Alarm Station (CAS) of nuclear power plant. Computers of the VR training system deploy an intrusion scenario in a virtual space. Trainees in a group sit in front of 3-D screens and play a role play game in a virtual CAS. Through the exercise, trainees are able to learn skills necessary to the contingency case of nuclear plants. In my presentation, I will introduce the two training courses, advantages and disadvantages of the VR training system, reactions of trainees and future plans.

Capacity-building is an important area, to be continually reinforced in order to maintain the successful operation of an entity or organization. The depletion of capable human resources due to retirement, ill-health and other unavoidable conditions should be addressed. Valuable knowledge and experience should be shared in a certain way; with ease of comprehension and information retention. Virtual reality (VR) is one tool that can be used in response to the urgent need to capture knowledge and experience from relevant resources. In 2016, the Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of the Japan Atomic Energy Agency (JAEA) invested in virtual reality knowledge management technology to equip its Center of Excellence. The ISCN has developed a VR system that provides a three-dimensional computer-generated training environment, which can be explored and interacted with by an individual. Through this VR system, the participant becomes part of a virtual world, immersed within the environment. While there, the individual is able to manipulate objects or perform a series of actions. This paper describes how virtual reality is being used by the ISCN as an effective capacity-building tool. It will also describe the approach to how the knowledge and experience for a specific subject matter are conveyed through the use of virtual reality. The effectiveness of the tool has been demonstrated since its introduction through application on several occasions within the training course for the State System of Accounting for and Control of Nuclear Material (SSAC). Use of the VR tool brings benefits from zero exposure to radiation within a suitable environment for the participants' training, whilst enabling the learning of safeguards concepts and associated nuclear material verification measures.

For the reduction of the external dose of workers in the process of Fukushima Daiichi Nuclear Power Station (1F) decommissioning and to propose an effective decontamination plan, it is necessary to grasp the distribution of locally existing hotspots. A one-dimensional radiation distribution measurement system applying time-of-flight method to scintillating optical fiber has been widely applied after the 1F accident, but in a high dose rate environment such as 1F reactor building, a pile-up of signal and chance-coincidence effect of a sensor is a problem. Therefore, as an integral-type measurement method that can avoid problems such as pile-up, we propose a reverse-estimation method which measures the wavelength spectrum at the fiber edge and estimates the incident position of radiation to the fiber using the fact that the attenuation length of light depends on the wavelength.

The Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN), of the Japan Atomic Energy Agency (JAEA), has been involved in strengthening the capacity-building efforts of the Asian region. ISCN provides training courses for capacity-building through human resource development. ISCN has developed several training curriculums involving VR technology and has been using them in regular courses since 2012. For efficient development, the existence of engineers who helped with communications between software programmers and trainers of the relevant training is important. As the themes of the training become more specialized, a larger budget and more time for development may be required however the number of potential users may be reduced. Therefore, a careful feasibility study is necessary before developing the training curriculums. VR technology can make a contribution to improve the efficiency and effectiveness of training. It is important to combine the use of real equipment and/or real facilities with the use of VR technology.
