Japan Atomic Energy Agency (JAEA) is developing ARKADIA (Advanced Reactor Knowledge- and AI-aided Design Integration Approach through the whole plant lifecycle) to meet the expectations for safe, economical, and sustainable carbon-free energy. The Knowledge Management System (KMS) included in ARKADIA consolidates technical information on Sodium-cooled Fast Reactor development obtained from "Monju" and other projects. Currently, several search functions are being developed in KMS. First, indexes are added to the documents. In addition, a search function has been enhanced to enable cross-search of all information registered in KMS. Furthermore, information retrieval using knowledge graphs is being developed to enhance information retrieval. This function can integrate rules, standards, interpretations, guidelines, design information, and related feasibility check information into a knowledge graph. Finally, milestones in KMS development and further enhancements are presented.
