Proceeding of the 20th technical meeting on nuclear reactor and radiation for KURRI engineers and the 11th technical official group section 5 meeting in Kyoto University

Five presentations were given with a focus on the measures for the Fukushima Daiichi Nuclear Power Station accident. (1) 'Support activities of KURRI on the measures for the Fukushima nuclear accident': Introduction of the state of personal dispatch and support activities for radiation survey performed at evacuation centers. (2) 'New RI usage-emitting α-ray aiming at single cell': Developing state of a new cell irradiation effect observation system that can perform the localized irradiation of RI-derived He ion while targeting single cell under a microscope. (3) 'Reactivity measurement system at Kyoto University research reactor (KUR)': Explanation of the composition and performance of the system of real time display on the output, reactivity, and cooling water temperature of KUR, etc. and the introduction of that this system used in student experiments. (4) 'Introduction of GPS-linked automatic radiation measuring system, KURAMA': Introduction of a voluntarily developed vehicle-mounted type radiation measurement system that takes into account the local conditions of Fukushima (KURAMA). (5) 'Internal exposure dose evaluation of staff members dispatched to Fukushima': Indication of the methods and results of dose assessment, and report on that exposure management has been properly performed. The 3 of 5 papers presented at the entitled meeting are indexed individually. (A.O.)
