which type of storage facility is assumed to be safe for long-term storage of nuclear waste products
Radioactive waste The ongoing controversy over high-level radioactive waste disposal is a major constraint on the nuclear powerâ€™s global expansion.[39] Most scientists agree[40] that the main proposed long-term solution is deep geological burial, either in a mine or a deep borehole. However, almost six decades after commercial nuclear energy began, no government has succeeded in opening such a repository for civilian high-level nuclear waste,[39] although Finland is in the advanced stage of the construction of such facility, the Onkalo spent nuclear fuel repository. Reprocessing or recycling spent nuclear fuel options already available or under active development still generate waste and so are not a total solution, but can reduce the sheer quantity of waste, and there are many such active programs worldwide. Deep geological burial remains the only responsible way to deal with high-level nuclear waste.[41] The Morris Operation is currently the only de facto high-level radioactive waste storage site in the United States.
