Outline of International Nuclear Human Resource Development Program (Instructor Training Program: ITP), which is sponsored by MEXT, for Asian ten countries by JAEA will be reported. ITP consists of three major activities, i.e. Instructor Training Course, Follow-up Training Course and Nuclear Safety seminars. 16 years training activity from 1996 at JAEA and Asian countries has developed around 160 of instructors and more than 2,000 of trainees in Asian countries.

Actinides (Th, U, Np, Pu, Am, Cm) are important nuclides for the analysis of radioactive wastes from nuclear facilities. In order to achieve simple and rapid analysis of actinides, capillary electrophoresis-laser-induced fluorescent detection method (CE-LIF) is one of the potential candidates. In this study, new emissive probes of uranium suitable for CE-LIF were developed. The detection and separation of uranyl ions were examined using several new emissive complexing probes, each of which possessed a fluorophore and a different chelating moiety. Using acyclic tetradentate probes, the highly sensitive fluorescent detection of uranyl ions was successfully achieved. The detection limit of mid-ppt levels was determined.

For decommission of uranium handling facilities, it is important to characterize the details of the facilities, which are the distribution of nuclide, the existence of hazardous waste and so on. The report mainly shows the character of distribution of uranium and its isotopes.

The computational technique using the ray of two energies emitted from 
U progeny nuclide (
Pa) was developed to determine uranium quantity in heterogeneous waste. In this study, the relative error and detection limit evaluation results using the simulated wastes are reported.

Use of Rock-like oxide (ROX) fuel is proposed for the purpose of reduction of plutonium amount in the case of gradually stopping nuclear power generation without introducing fast breeder reactors. In this study, the mass flow and repository of three scenarios that is once-through, Pu-thermal and ROX, was analysed. As the result, amount and attractiveness as nuclear weapon of Pu was decreased in the ROX scenario in comparison with the once-through scenario, although the repository size was not reduced.

The characteristics of fast reactor safety is that it has passive safety function such as natural circulation heat removal. Hence, it is necessary to evaluate the reliability of the passive safety function and to estimate probability of the functional failure in order to perform level 1 PSA on a plant. This paper reports sensitivity analysis and failure probability evaluation in 2011 to construct failure probability evaluation methodology on natural circulation decay heat removal.
