Currently, many nuclear power plants have adopted dry storage to resolve the problem of insufficient storage capacity of spent fuel pools. According to statistics of the Atomic Energy Council, Taiwan, as of the end of December 2018, 24 countries around the world have set up dry storage facilities, including the United States, Canada, and Germany. There are currently 131 dry storage facilities in use, and another 9 are under construction, or waiting to begin operations. This shows that dry storage is already widely used and mature as a spent fuel storage technology in the international arena.
It has been 30 years since the first dry storage facility in the United States began operations in 1986, and it has been approved to operate until 2046, for a total of 60 years, which shows that dry storage is reliable.
Currently, countries around the world that have adopted outdoor open-air storage include the United States, South Korea, and China. Countries that have adopted both indoor and outdoor storage include Spain, Canada, Lithuania, South Africa, and Japan. Countries that have adopted indoor storage include the United Kingdom, Czech Republic, Hungary, Germany, Switzerland, Bulgaria, Belgium, and Slovenia.
