In Taiwan, there are six operating nuclear power plants that annually produce {approximately}6,000 drums of low-level radioactive waste (LLW). Some of these LLW drums are stored temporarily on an off-island, Lan-Yu. The current plan for safe disposal of LLW calls for its emplacement in a below-ground concrete vault (BGCV). As Taiwan is densely populated, it is reasonable to develop such an LLW repository on some off-islands. Since some radioactive nuclides will eventually release to the biosphere after disposal, the radiological assessment of the repository should be made before its development. Recently, Kim et al. employed a simplified probabilistic risk analysis method to evaluate the safety of a land-buried LLW repository with the disposal of one batch of waste only. The purpose of this study is to assess the radiological impact of a BGCV repository on an off-island. The authors extend Kim et al.'s model with an additional layer of concrete barrier and a changing of the disposed numbers.
