Abstract: [Background] Data archiver is an important part of the molten salt reactor control rod drive mechanism (CRDM) prototype control system. It is used to store real-time parameters, alarm and other information of equipment, etc., and accumulate data for further data-based prognostics and diagnostics. [Purpose] This study aims to develop a CRDM data archiver based on PostgreSQL. [Methods] A dual-machine hot standby technique was employed to improve the performance of database and store data reliably. The control rod position retrieval tool was implemented by using Java programming. [Results] A data archiver based on PostgreSQL was developed and applied to CRDM prototype. [Conclusion] The data archiver designed based on PostgreSQL is proved to be an advanced, low cost and stable system.
