The Chinshan Nuclear Power Plant, which consists of two BWR units and was owned by Taiwan Power Company (TPC), has an electrical output of 636 MWe for each unit. Unit No. 1 and Unit No. 2 were licensed till December 2018 and July 2019, respectively. According to regulations of decommissioning in Taiwan, decontamination and dismantling of a NPP should be completed within 25 years. Therefore, TPC had started compiling the decommissioning plans (DP, 17 chapters) with INER, national engineering companies and international consultants since 2012. The DP of Chinshan NPP has been approved by the regulator, Atomic Energy Council (AEC), in the end of June, 2017. There are 17 chapters in the decommissioning plans, which deal with all aspects of safety-related considerations during the decommissioning period, such as spent fuel management, waste management, personnel/workers planning, schedules/working items, environmental management and monitoring. Those items are discussed in detail in this paper in accordance with the approved DP. The implementation of decommissioning will be started while the Environmental Impact Assessment (EIA) is still under approval by EPA, which is expected to be completed in the end of 2018 or the mid of 2019. Once the decommissioning be started, all dismantling, decontamination, management teams, and preparation would be kicked off simultaneously in a very short period of time. In this paper, the planning assumptions, strategies from INER and TPC, management of radioactive waste, conversion of Turbine Building and detailed description of turbine-generator set are discussed. For the Turbine Building dismantling, inventories of equipment, cutting technology determination, storage logistics, container options and radwaste treatment and reduction would be important factors to be evaluated in the beginning. Afterwards, WBS (work breakdown structure) would be determined and be the basis for working bids, construction of a new storage warehouse, an incinerator and a super high pressure compactor. This preliminary engineering planning would be applied in the decommissioning of Chinshan NPP for the first time and be duplicated in Kuosheng NPP and Maanshan NPP in Taiwan as well. (authors)
