| Research Abstract |
Recently importance of nuclear energy has been recognized again due to serious concerns of global warming and energy security. It is one of the critical issues to verify safety capability of ageing nuclear power plants subjected to big earthquake. In this research, we develop a simulator of quantitatively predicting actual function limit of nuclear power plants.
In this research, a Boiled Water Reactor (BWR) model that is offered by Tokyo Electric Power Company and Hitachi, Ltd. is considered. The finite element model contains 200 million DOE The system that seismic analyses and visualizations for large scale models are performed efficiently on the Earth Simulator was developed.
Furthermore,
1. Development of a method by which to incorporate a set of linear multipoint constraints (MPC) into the Balancing Domain Decomposition method
2. Development of tools to support the simulation of assembly structures with MPC
3. Introduction of moving boundary condition to the program of incompressible flow analysis
4. Introduction of thermal analysis to the program of incompressible flow analysis
5. Improvement of the explicit dynamics solver for elastic stress analysis
6. Development of a method for a numerical analysis of brittle fractures
7. Research and development of an iterative partitioned coupling algorithm
8. Development of coupled analysis engine with coupler
were done. Development of the system that supports design and development of BWR was completed.
