Swedish government approves final disposal site plan to store spent nuclear fuel for 100,000 years
The Swedish government has approved a plan to build an encapsulation facility required for the disposal of spent nuclear fuel and a final disposal site for spent nuclear fuel. In Sweden, the government, Swedish Nuclear Fuel and Waste Management Company (SKB), universities, research institutes, etc. have been conducting research on the disposal of nuclear fuel for more than 40 years, and at this final disposal site, spent nuclear fuel will be radioactive. It will be stored until 100,000 years after it decays.

Swedish government was approved, Oskarshamn and spent nuclear fuel enclosed facility to be built in the city, Esutohanmaru is spent nuclear fuel final disposal site to be built in Forsmark of the city.
In Sweden, we have been conducting research on the disposal of spent nuclear fuel for more than 40 years since the 1970s when we started operating nuclear power plants, and it is harmful with three things: 'copper storage container', 'bentonite that hardens the surroundings', and 'rock'. We have developed a method called 'KBS-3' that protects people and the environment from heavy radiation.
The final disposal site this time will also be built according to this 'KBS-3', and the final disposal site will consist of 500 tunnels dug at a depth of 500m. The total length of the tunnel is 60 km, the plane area is 3 to 4 square kilometers, and 12,000 tons of spent nuclear fuel will be stored in 6000 copper storage containers until 100,000 years after the radioactivity decays.
According to the announcement, 'KBS-3' was evaluated by the Swedish Radiation Safety Authority as 'the best technology for final disposal', and the country with such advanced nuclear waste management is 'KBS-' as well as Sweden. It is said that it is only Finland that uses '3'.
In addition, this step is only 'approved by the government', and in the future, the land environment court will establish the conditions of the facility, and the Swedish Radiation Safety Authority will decide the permit conditions based on the Nuclear Activity Law. It is said that the construction will start after all are approved. In addition, the construction itself will take about 10 years, so it will be 70 years after the final disposal site is completed and the storage of spent nuclear fuel will begin.
