국내 방사성폐기물 통합적 관리를 위한 폐기물 추적관리 시스템 시나리오 연구

Abstract

Currently, domestic agencies that are generating radioactive wastes, such as nuclear power plants, KAERI and KNFC, implemented their own WTS system and have been operating them. They have difficulty with integrated management of wastes from their generation to transportation to disposal site. Also, as different agencies have different waste classification criteria, it is difficult state to easily track and manage wastes from the viewpoint of acceptance and regulation. As for the Waste Tracking System of each waste generating agency, KHNP (Korea Hydro & Nuclear Power Co., Ltd.) has DREAMS (Digital Realtime Enterprise Management System). And KINS has WACID (WAste Comprehensive Information Management), and KAERI has RAWMIS (Radioactive Wastes Management Integration System). Furthermore, KNFC has MES (Manufacturing Execution System). As for the waste classification criteria, KHNP and KAERI separately classifies cotton and paper as combustible, and steel and aluminum as non-combustible, and KNFC separately classifies dry active wastes, compounds, lime sediments, etc. Also, the entire process of managing the various low and intermediate level radioactive wastes, generated by KHNP, KAERI and KNFC (solid, liquid, gas, sludge, etc.), is incomplete, and the management of information on transportation and movement is inadequate. Also, an entire process scenario from generation of radioactive wastes during the decommissioning of nuclear power plants to treatment and disposal of radioactive wastes is required. Accordingly, this paper examined the current status of the Waste Tracking Systems (WTS) in domestic and overseas, and analyzed the criteria for classifying low and intermediate level radioactive wastes of individual agencies in domestic. To build an integrated WTS, the radioactive wastes classification criteria of different agencies were integrated. Codes were assigned to each generating agency, location and transportation. The “low and intermediate level radioactive waste transportation inspection result” was referenced, and the scenario for moving radioactive wastes from the waste generator, Hanbit Nuclear Power Plant, to the acceptor, Korea Radioactive Waste Agency in Gyeongju, was prepared. Additionally, this paper presented the location of wastes in the repository and the management form of the code values resulting from the preparation of the scenario, which are the shortcomings, by preparing the WTS scenario.
