JAEA has supported to HRD of mainly Asian countries in the field of SGs and SSAC, and works closely with governmental organizations in Japan, and with the IAEA, the U.S. DOE, EC, the flame work of FNCA, APSN. This paper presents the efforts, contributions and future challenges of JAEA to HRD regarding SGs and SSAC, through international cooperation, which have been taking place for around 20 years.

The Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) provides training courses for Asian countries and the domestic concerned parties. ISCN has developed its original curriculum for these courses jointly with the Sandia National Laboratories (SNL) in the U.S. The base of the curriculum was the training course on the physical protection training course developed by SNL. In cooperation with SNL, ISCN developed the Physical Protection Exercise Field and the Virtual Reality system as tools for its original training programs. ISCN has already received over 1,200 participants from 33 countries (including Japan) to its human resources development activities (as of June 2013). In addition, ISCN expands its activities to organize workshops in order to promote understanding of the IAEA's revised recommendation on the physical protection of nuclear material, and to foster the nuclear security culture. Here, these activities of ISCN will be introduced.

The Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of the Japan Atomic Energy Agency has started its human capacity building activities, domestically and internationally, for the government officials and employees of companies of emerging nuclear power countries mainly in Asia. In this paper, I will describe the activities of ISCN on capacity building for these countries and also I will briefly describe, focusing on nuclear security, the activities of IAEA, Sandia National Laboratory of United States and the development of human capacity building support activities of neighboring countries of China and Korea. By doing this, I will describe the relationship and cooperation of ISCN with these organizations and talk about my personal views of the future development with these organizations and ISCN.

At the 2010 Washington Nuclear Security Summit, Japan committed to establish a regional center for the strengthening of nuclear security, mainly in Asia, through capacity building support including human resources training and infrastructure development assistance. In accordance with this statement, the Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) was inaugurated in December 2010 in Japan Atomic Energy Agency (JAEA). This paper describes the ISCN training activities and introduces the developing new training course on physical protection.

Risk of cataract after low-dose exposure to radiation has drawn an attention; however, its onset mechanisms remain uncertain. In recent years, based on 
experiments using human lens epithelial cells (HLEC1), it has been reported that irradiation with higher dose than 2 Gy can enhance cell proliferation (excessive proliferation), which is suspected as an important factor for dose response for cataract. In this study, to clarify the excessive proliferation for the HLEC1 cells, we developed a model for predicting colony formation after exposure using agent-based model, NetLogo. This model newly considers the premature aging and DNA damage repair processes, and was compared to the experimental probability density of colony size. The model predictions considering the premature aging was in good agreement with the experimental colony size, while we succeeded in reproducing measured cell-cycle distribution using the model accounting DNA repair process. This model analysis suggests that the premature aging of the HLEC1 cells is an important factor for determining the proliferation ability. The developed model can contribute to analyzing the underlying mechanisms for clonogenicity of the HLEC1 cells after exposure in future study.
