Integral Fast Reactors are not a solution for the short term. There are currently no Integral Fast Reactors in commercial operation and the research reactor that was to be constructed by the United States was canceled in 1994. Any attempt to use IFRs to recycle all of the world’s nuclear waste would be very expensive and would not be an immediate solution – the waste would need to be stored somewhere while it waits to be used by the new reactors.
