Searching for effective pathways for the production of proton- and neutron-rich isotopes through an optimal combination of reaction mechanism and energy is one of the main driving forces behind experimental and theoretical nuclear reaction studies as well as for practical applications in nuclear transmutation of radioactive waste. We report on a study on incomplete fusion induced by deuteron, which contains one proton and one neutron with a weak binding energy and is easily broken up. This reaction study was achieved by measuring directly the cross sections for both proton and deuteron for $$^{107}$$Pd at 50 MeV/u via inverse kinematics technique. The results provide direct experimental evidence for the onset of a cross-section enhancement at high energy, indicating the potential of incomplete fusion induced by loosely-bound nuclei for creating proton-rich isotopes and nuclear transmutation of radioactive waste.

JAEA was assigned as a designated public institution under the Disaster Countermeasures Basic Act and under the Armed Attack Situations Response Act. Based on these Acts, the JAEA has the responsibility of providing technical support to the national government and/or local governments in case of disaster responses or response in the event of a military attack, etc. In order to fulfill the tasks, the JAEA has established the Emergency Action Plan and the Civil Protection Action Plan. In case of a nuclear emergency, NEAT dispatches specialists of JAEA, supplies the national government and local governments with emergency equipment and materials, and gives technical advice and information. In normal time, NEAT provides various exercises and training courses concerning nuclear disaster prevention to those personnel taking an active part in emergency response institutions of the national and local governments, police, fire fighters, self-defense forces, etc. in addition to the JAEA itself. The NEAT also researches nuclear disaster preparedness and response, and cooperates with international organizations. In the FY2013, the NEAT accomplished the following tasks: (1) Technical support activities as a designated public institution in cooperation with the national and local governments, etc. (2) Human resource development, exercise and training of nuclear emergency response personnel for the national and local governments, etc. (3) Researches on nuclear disaster preparedness and response, and sending useful information (4) International contributions to Asian countries on nuclear disaster preparedness and response in collaboration with the international organizations

When a nuclear emergency occurs in Japan, the Japan Atomic Energy Agency (JAEA) has the responsibility of providing technical support to the National government, local governments, police, fire stations and nuclear operators etc., because the JAEA has been designated as the Designated Public Institution under the Basic Act on Disaster Control Measures and the Act on Response to Armed Attack Situations, etc.. The Nuclear Emergency Assistance and Training Center (NEAT) of JAEA provides a comprehensive range of technical support activities to an Off-Site Center in case of a nuclear emergency. Specifically, NEAT gives technical advice and information, dispatches specialists as required, and supplies the National Government and local governments with emergency equipments and materials. NEAT provides various exercise and training courses concerning nuclear disaster prevention to those personnel taking an active part in emergency response organizations at normal times. The tasks of NEAT, with its past experiences as a designated public institution including the responses to TEPCO's Fukushima Accident, have been shifted to technical supports to the national government for strengthening its abilities to emergency responses; the NEAT therefore focused on maintenance and operation of its functions, and strengthening its response abilities in cooperation with the national government. This annual report summarized these activities of JAEA/NEAT in the fiscal year 2012.

North Korea carried out the third nuclear test in February 2013. Due to the request of the Ministry of Education, Culture, Sports, Science and Technology (MEXT), Nuclear Emergency Assistance and Training Center (NEAT) and Nuclear Science and Engineering Directorate (NSED) of JAEA predicted the atmospheric dispersion of radionuclide by WSPEEDI-II for the purpose of contributing to the environmental monitoring plan. From February 12 to 22, they provided daily reports on the prediction to the MEXT and the Ministry of Defense. MEXT has published these reports on the website. Since April 2012, NEAT and NSED had prepared to predict by the framework for the prediction around the clock during 10months until February 2013. This report described this experience and pointed issues out on this system.

This work evaluated the dynamic traffic flow of evacuees' cars during the evacuation drill with family car conducted in the Ibaraki Prefecture Comprehensive Nuclear Disaster Exercise 2010. The opinion survey was also conducted to participants to get the data of choice of measures for evacuation. Consideration based on the survey of this drill revealed important outcomes as follows. (1) The evacuation routes should be chosen more than one per one residential district from the roads including low capacity road to ease traffic congestion and to secure substitute route. (2) Taking into account traffic control and guiding at the intersections on the evacuation routes by policemen and staffs is very important to make the vehicles of evacuees running smoothly. (3) Considering of the capacity and the gate size of the parking of reception center is very important to make the stream of vehicles smooth when Reception centers are chosen. (4) Considering of the effect from experiments of participants is important for the opinion surveys to get the choice of measures of evacuation. (5) The opinion surveys about evacuation from nuclear disaster should be done in the wide area including the outside of the evacuation zone.

The International Search and Consequence Management Workshop (ISCM-WS) that was organized by the U.S. Department of Energy (DOE) took place from May 17th to May 20th, 2010. The Aim of this Workshop is to build and enhance the global capacity to prevent and respond to nuclear and radiological emergencies, and it directly supports the aims of global initiative to combat nuclear terrorism. DOE brought together 92 officials from 26 countries and 3 officials from IAEA in this Workshop. DOE introduced two matters in USA, First is response against nuclear and radiological terrorisms and second is technology, systems, activity for consequence management. This review report summarized the observation in the ISCM-WS including activity of DOE/NNSA's Search Response Team and activity of consequence management.

"Drill of evacuation with family car", "Drill of evacuation for the disabled with family car", and "Evacuation drill from the large enclosure" had been conducted in the National Comprehensive Nuclear Disaster Exercise on December 21st and 22nd, 2009 in Ibaraki Prefecture. This work evaluated the dynamic traffic flow of evacuees' cars during the evacuation drill using three kinds of data, i.e. questionnaire for the participants in the evacuation drill, GPS tracking data of vehicles of evacuees, and photographies shot from the air and ground. The fluctuations of traffic volume influenced by traffic controls for the outside of evacuation zone was evaluated using the traffic volume data which were provided by Ibaraki prefecture. The opinion survey was also conducted to participants of evacuation drill for three purposes, to get the data of choice of measures for evacuation, to find out problems of evacuation for the disabled, to find out problems of evacuation from the large enclosure.
