The inevitable increases of food production and energy consumption with an increase in world population become main causes of an increase of nitrate load to the environment. Although nitrogen is essential for the growth of animal and plant as a constituent element of protein, excessive nitrate load to the environment contaminates groundwater resources used as drinking water and leads to seriously adverse effects on the health of man and livestock. In order to clarify the problem of nitrate contamination of groundwater and search a new trend of technology development from the viewpoint of environmental remediation and protection, the present paper has reviewed adverse effects of nitrate on human health, the actual state of nitrogen cycle, several kinds of nitrate sources, treatment methods for reducing nitrate level, etc.

This presentation provides a concise overview of knowledge and experience gained from the activities for environmental remediation after the Fukushima Daiichi (1F) accident to establish the technical basis for strategic, off-site response to nuclear incidents. It reflects JAEA's key role in the research associated with both remediation of contaminated areas and also the natural contamination migration processes in non-remediated areas. This presentation also provides a perspective on the future actions required to remediate all areas outside the 1F site, where continuing R&D is essential to facilitate return of residents to the most contaminated zones from the standpoint of environmental chemistry and radiochemistry with special emphasis on associated waste management.

The Japan Atomic Energy Agency, JAEA, as Japan's sole comprehensive research and development institute in the field of nuclear science, has been missioned to deploy technical support for post-accident environmental remediation and decommissioning of the disabled Fukushima Daiichi Nuclear Power Station. Immediately after the 2011 nuclear accident, JAEA launched the environmental decontamination pilot project to examine the applicability of various environmental decontamination technologies, radiation measurement for a wide range of areas including both contaminated areas within the Fukushima prefecture (car-borne radiation surveys) and also the entire land of Japan (air-borne monitoring technologies). In addition to these "off-site" activities, JAEA stepped up research and development in 2015 to support "on-site" decommissioning of the crippled nuclear reactors and contaminated power station site. JAEA's R&D charge covers a wide range of differing technologies and disciplines needed for decommissioning. Techniques range from remote control technology development for dismantling jobs and workers' safety under inaccessibly high radiation environments, analysis and characterization of radioactive waste and fuel debris generated by the accident, to fundamental research for accident scenario analysis and innovative radiation detecting technology development. In addition, JAEA has built specialist infrastructure devoted to these tasks. The decommissioning of the post-accident nuclear power station site and environmental remediation will be a long lasting endeavor, projected to take 30 to 40 years to complete, and therefore, development of human resources is essential. JAEA's R&D sites could serve as a platform for domestic and international human resource development through training and education within our R&D facilities, which importantly, would contribute to knowledge and technology transfer to future nuclear generations.

Japan Atomic Energy Agency (JAEA), as a designated public institution in the "Disaster Countermeasures Basic Law", has been carried out research and development relating to the accident of TEPCO Fukushima Daiichi Nuclear Power Station (1F) such as radiation measurement, and sent experts. In this presentation, current status of decommissioning, establishment of organization and research institutes, and out-line of research and development are briefly introduced. Recent topics of research results of JAEA are reported.
