Abstract
Various engineers from different generations are concerned in geological disposal project of high-level radioactive waste (HLW) over long time. It requires to manage information to ensure the traceability of the decision making process and the inheritance of technique involved in project management.
We developed an Expert system available on the Web to manage inheritable knowledge related to procedure, know-how and the notice of investigation techniques for deep geological environment. This report provides an overview of Expert system and the one of contents regarding hydrochemical modeling and the updating method in Literature survey stage ~ Detail investigation stage of geological disposal project.
