Several countries are moving full speed ahead on next-gen nuclear reactors that can use reprocessed spent nuclear fuel. The US is not one of them, even though it has vast (and expensive to store) stockpiles of spent fuel being warehoused.
Will nuclear energy be a major source of power in the coming decades? Many countries think so and are planning for it. But the US lags way behind, even as its stockpiles of spent fuel grows ever higher.
Are there risks in reusing spent fuel? Yes. But there are risks in storing it too. Unless you think that renewables can handle all the load for power generation in the coming years as oil gets more expensive and coal not politically or ethically possible, then, like it or not, nuclear power will play a major role.
