Building Reliable Houses for LLW – Development of Low-Level Radioactive Waste Container

Published：2024-04-02  13:39

【Technical Introduction】
Following the nuclear-free homeland policy, all of the nuclear power plants in Taiwan will step into the decommissioning phase by the end of 2025. Besides, the dismantling of Taiwan Research Reactor (TRR) vessel was started in 2021. In order to safely and effectively store those massive low-level radioactive wastes (LLWs) generated during the decommissioning of these nuclear facilities, dedicated containers need to be developed and implemented. To fit the requirement, NARI had developed two types of LLW containers, INER-LRW-C1 and INER-LRW-C2 LLW containers (C1 and C2 containers). The usage permits of C1 and C2 containers were granted in 2020.

Development of C2 Container

【Project Planning/Technology Application】
C1 and C2 containers were developed for the purpose of storing dry and solid LLWs produced during the decommissioning of the nuclear facilities in Taiwan. C1 containers have been used to store the dismantled reactor vessel wastes of TRR. In the near future, the LLWs coming from the internals of reactor vessel being segmented under the water will be stored in C2 containers. Adopting the containers developed in-house will significantly reduce the decommissioning cost and operational risk.


C1 Containers Storing the Dismantling Wastes of TRR Reactor Vessel

【Future Plan】
C1 and C2 container technical transfer and authorization will be utilized to team up NARI and domestic vendors to gain the market share of the LLW containers in Taiwan. It is estimated that the market share in the field of domestic nuclear decommissioning and operation costs about several billion NTD. Through this way, NARI and domestic vendors can share the benefit that C1 and C2 containers bring in.
