Fourth-generation reactors and nuclear-waste recycling
Researchers aim to produce safe nuclear fuel that can be 80 percent recycled, compared to the current 1 percent; these fourth generation nuclear power systems can lead to a reduction of the amount of high-level, long-lived nuclear waste to a tenth of what it is today, while energy output can increase hundredfold.
“If it is possible to recycle as much as we think, at least 80 per cent of nuclear waste will be possible to recycle,” says Christian Ekberg. “This would also mean that eight times as much of the remaining waste could be included in the final repository, since heat generation is reduced. In addition, the amount of long-lived nuclides in residual waste is reduced, which results in a significantly shorter storage period. However, it is important to remember that the final repository is still an important part of the fuel cycle.”
