Improvement and upgrading on the waste disposal FEP information database system

This year, we have improved and upgraded the waste disposal FEP information database system which has been produced at JNC until last year. In this year's improvements and upgrading, a standard graphics user interface builder was utilized instead of commercial tools limited to particular models, thus making the system commonly available for both server and client regardless of the model and enabling a reduction of the operating environment. Because of these improvements, the system is flexible with respect to future expandability (use of standard tools) and maintainability (standardized operations). Additionally, by enabling to add information about the biosphere to this system efficiently, the biosphere scenario can be handled by the same operations as the conventional groundwater scenario. From here, upgrading the window and operability toward the practical application and publication of the information through the internet (with analyzing the public views on the FEP scenario by collecting opinions from the general public in an interactive manner) have to be done. Assuming these tasks are carried out, the issues that need to be addressed in the future are to incorporate the planning of the FEP scenario and the influence diagram, their explanation, etc. and to make the influence diagram clearer and more comprehensible for the purpose of distributing the waste disposal FEP scenario development research to the general users in a comprehensive form.
