A level 3 probabilistic risk assessment (PRA) is an offsite consequence analysis for a severe accident and estimates the frequency and severity of the consequences to the public. Probabilistic accident consequence assessment models and computer codes are an integral part of level 3 PRA of nuclear power plants. Our research group has developed a level 3 PRA code, OSCAAR. In this theme, researches on the probabilistic accident consequence assessment for health effects and economic consequence are conducted considering site-dependent on metrological, population, agricultural and economic data by using OSCAAR. | ||||||

Experimental nuclear physics programs dedicated to exotic nuclei such as neutron-rich, proton-rich and super-heavy nuclei will be promoted. Challenge to find a new phenomenon in nuclear structure, nuclear reaction and fission processes will be highly encouraged. Experiments will be carrieod out using JAEA facility and also other facilities inside and outside Japan to produce exotic nuclei and unique states in nuclei.

A successful candidate will theoretically study spin- and thermal-transport properties using some numerical techniques such as density functional theory, density matrix renormalization group method, quantum Monte Carlo method and so on. Thermoelectric materials, primarily related to spin Seebeck effect, and radiation-proof devices will be also important subjects of candidate. | ||||||

Scattering power of protons against neutrons remarkably depends on relative direction of spins of the protons and neutrons. We have developed a dyanamic nuclear polarization system for the proton polarization of composite materials, and then carried out polarized neutron scattering study to determine detailed structure of the materials. We will extend this technique named spin contrast variation to deterimine nano-scale bulk and surface structures using small-angle scattering diffractometers and reflectrometers at the neutron facilities, JRR-3 and J-PARC. | ||||||

The decommissioning of a nuclear facility is a long term project. The transfer of knowledge and education to the next generation is a crucial issue. It is necessary to systemize of knowledge based on the knowledge engineering method such as ontology. Concretely speaking, we collect a large amount of explicit knowledge regarding decommissioning such as domestic and foreign information, instruments information and know-how, and arrange it. On the other hand, we try to translate personal tacit knowledge collected by interview to explicit knowledge as possible. After these, we can use whole knowledge of decommissioning organized and systematized, and study advanced knowledge engineering method available for education and succession. | ||||||

Towards the planned removal of fuel debris from the TEPCO Fukushima Daiichi Nuclear Power Plants in 2021, reduction of radiation doses to workers and countermeasures against the spreading of radioactive contaminations are essential. For the purpose, three-dimensional visualization (mapping) of dose rates and radionuclide distributions are required as well as the real time monitoring of dose rates in the reactor building. So far, developments on radiation measurement techniques in the Fukushima Daiichi NPPs are in progress, and results obtained from these developments are to be visualized by the proposed R&Ds. Especially, developments of the algorithm for the three-dimensional image reconstruction is to be performed. |
