[en] At present, radwastes of KAERI are managed under various divisions according to their generation characteristics and final disposal of radwastes of KAERI will be begun from 2015. So, effective management plan for KAERI radwastes is needed. As a short term management plan, classification and management of radwaste according to new category for radwaste, wrapping up treatment of radwaste generated from Seoul research reactor decommissioning and operation of WCP and management division were suggested. And as a mid term management plan, setting up disposal priority considering management division and radioactivity concentration of radwaste and enlargement of deposit for final disposal, and setting up disposal system for Ki-Jang research reactor were suggested. Finally, as a long term management plan, minimization and effective management of radwaste generated from decommissioning of nuclear fuel cycle facilities and operation of disposal system for intermediate level radwaste were suggested. The results of this study will be applied for preparation of foundation of effective final disposal plan for radwaste at KAERI and meeting national policy for radwaste and increasing public acceptance for KAERI.
