Research in nuclear emergency preparedness information technology. Studies on the standardization of nuclear emergency preparedness data collection and transfer have been conducted, and a nationwide nuclear emergency preparedness resources management system has been established and efforts are constantly made to improve it. Development of a nuclear emergency preparedness information system, innovative modularization of nuclear emergency preparedness plan, automation of response process, visualization of organization and command and auxiliary scientific decision-making have led to the integration of routine management with emergency response, which has also helped enhance nuclear emergency preparedness response capabilities and organizational efficiency.

Research in nuclear emergency preparedness medical treatment technology. Research on the technology of diagnosis and treatment for acute radiation injuries has been carried out, and guidelines for diagnosis, treatment and rescue for acute radiation injuries have been developed. Key technical and promotional application research in unexpected nuclear radiation events has resulted in the development of methods for rapid biological dose assessment for nuclear radiation accidents applicable for the general public, which has helped optimize non-myeloablative stem cells and mesenchymal stem cells (MSC) combined transplantation treatment for severe and extremely severe bone marrow acute radiation patients. A number of breakthroughs in the treatment of radiation diseases have been achieved, leading to a reduction of casualties of nuclear radiation accidents to the maximum extent. With primary and clinical research on the treatment of radiation injuries by use of mesenchymal stem cells, a new therapy using transplantation of combined MSC and hematopoietic stem cells for severe radiation sickness has been created. The research achievement “Establishment and Application to Treat Radiation Diseases by Using Somatic Stem Cells” won a first prize for national science and technology improvement. A “three-level handling and four-level treatment” systemized nuclear emergency medical rescue capabilities development model has been developed by China's military medical research organizations.

Research in public risk communication and psychological assistance. Research in mass psychological assistance techniques under circumstances of unexpected event (accident) has been conducted, and relevant psychological intervention models have been established, and countermeasures, criteria and implementation guidelines have been proposed. In view of the characteristics of nuclear radiation, Q&A publications in relation to nuclear accident protection and applied books on medical countermeasures in case of nuclear and radiological accidents geared toward the public have been compiled.

Innovative research in nuclear emergency environmental meteorology. A numerical prediction system of China's meteorological environmental emergency response is being developed and improved. Following the upgrading of the meteorological service system for nuclear and hazardous chemicals leakage and improvement of atmospheric dispersion modeling by way of technology import and self-reliant R&D, the global mode resolution has been enhanced to 30km from about 85km, and medium-scale model resolution has been enhanced to 10km from 15km, realizing a more detailed and precise simulation and prediction of pollutant dispersion.

VIII. International Cooperation and Exchanges in the Field of Nuclear Emergency Preparedness

As a member state of the International Atomic Energy Agency (IAEA), China has always been, along with the other members, dedicated to promoting the development of an international nuclear safety emergency system and the sharing of achievements resulting from the peaceful use of nuclear energy, and unswervingly supports and facilitates international cooperation and exchange in the field of nuclear emergency preparedness. China has launched multi-level and all-round cooperation in respect of nuclear emergency preparedness with international organizations, including the IAEA, and is stepping up collaboration and exchange in the field of nuclear emergencies with relevant countries.
