“…DD also has the advantage that it can significantly reduce the probability of occupational exposure compared with ID. On the other hand, DD has drawbacks, such as difficulty in maintaining the same personnel until the completion of decommissioning, an increase in maintenance and safety management costs, and a delay in site reuse, as it takes a long time [8,9,41,44,45,79,113,116,137].…”

“…We verified that radioactive waste produced during decommissioning for F3 could cause serious damage that cannot be recovered in the future if it is not systematically managed, so this aspect was provided priority [36][37][38]63,67,[71][72][73]108,113,145,148]. For advanced decommissioning nations, such as the USA, France, and Germany, technologies to handle concrete and metal waste, which accounts for most of the dismantled waste, have reached the commercialization level [108,113], and radioactive waste is reused in various areas, including in NPPs, through the deregulation of radioactive waste [75,76]. However, their safe handling methods are not secured for some specialized waste, so the waste is temporarily stored, and studies on how to handle this are currently underway [62,138].…”

The decommissioning of nuclear power plants (NPPs) is rapidly increasing because NPPs are not only no longer profitable in many cases but are also being decommissioned due to a lack of public acceptance or political reasons in many countries, particularly in Europe, following the explosion of the Fukushima Daiichi NPP. Accordingly, a significant body of research has focused on achieving safe, environmentally sound, and sustainable decommissioning in many countries where there is demand for NPP decommissioning. In order to achieve sustainable decommissioning that restores the NPP site to its pre-NPP environmental state, it is necessary to understand the safety, technology, and cost aspects as well as having the process and strategy to systematically promote them. Although there are a limited number of countries with experience and knowledge in the management of decommissioning multiple NPPs, researchers in countries just starting NPP decommissioning need diverse research information on how to formulate a sustainable decommissioning strategy as well as related factors. In particular, a systematic review of decommissioning strategies, such as DD, ID, and ET, and the influencing factors associated with each strategy is needed from the researcher’s point of view. In this regard, this study reviews the research literature on decommissioning strategies for nuclear power plants with a sustainable perspective. A systematic method involving a meta-analysis is used. The results of this study confirm that many researchers are most interested in DD and are dealing with ID and ET at the same level, but in reality, DD and ID are being adopted at similar rates. Thus far, only three ETs have been adopted in the United States. Most countries that have adopted ID are deemed to have been influenced by political decisions.
