As for Japan because it is energy security guaranty and the like, Japan continued the research and development of FBR ("Joyo", "Monju") and fuel cycle. In recent years, there are a growing interest in the long-term energy security and terrestrial environmental problem. And FBR cycle has again been observed, by the development of young country and the like. This year, reactor operation was reopened after about 14 years, "Monju" is the only prototype FBR reactor which it works as the Western Worlds, and the result of these research and developments is expected even worldwide. JAEA is carrying on international cooperation of "JAEA-CEA", "JAEA-DOE", GIF, IAEA, for the points of view "The efficient development", "Decrease of development risk", "Establishment of worldwide standard technology", "Monju" establishes to the position as base of international research and development, and JAEA makes the best endeavors to "Monju" carrying out worldwide contribution.

"Fast Reactor Cycle Technology Development (FaCT)" project has been conducted since 2006. In this project, design study and research and development (R&D) on innovative technologies for fast reactor (FR) cycle system are implemented in order to present the conceptual designs of commercial and demonstration facilities by 2015 and start operating demonstration fast reactor in 2025. The R&Ds has been stepped forward into the development stage to establish the realization of innovative technologies which bring excellent performance to fast reactor cycle system. The purpose of R&D by 2010 is to decide weather innovative technologies shall be adopted. So promoting R&D of FR, the project governance was organized. Furthermore, several possible R&D have been effectively carried out within the frameworks of international cooperation, such as GNEP, GIF, and INPRO.

In the fast reactor development, numerical simulation using analytical codes plays an important role for complementing theory and experiment. It is necessary that the engineering models and analysis methods can be flexibly changed, because the phenomina to be investigated become more complicated due to the diversity of the needs for research. And, there are large problems in combining physical propaties and engineering models in many different fields. In this study, the goal is to develop a flexible and general-purposive analysis system, in which the phisical propaties and engineering models are replesented as a programming languare or a diagams that are easily understandable for humans and executable for computers. The authors named this concept the Engineering Modeling Language(EML). This report describes the result of the investigation for latest computer technologies and software development techniques which seem to be usable for a realization of the analysis code system for nuclear engineering as an EML.
