The issue that concerns me about nuclear power isn't so much weapons (they tend to be well-guarded, and it's hard to make weapons from reactor fuel), but decomissioning.

The UK was one of the first countries to build nuclear reactors; no UK reactor has ever been fully decomissioned, and from what I can see we haven't even got a strategy - WP says they're still working out whether decomissioning should occur over a 20-year or a 100-year span. The UK's first nuclear reactor, Calder Hall, was built in the year of my birth, and decommissioning is estimated to take well into the next century; my grandchildren will have died of old age.

You can stand next to a thermonuclear bomb without a mickey-mouse suit; you can even open it up, take the components out, and render the weapon unusable, fairly easily. Nuclear reactors, not so much.

I have grandchildren under 5. Until we've proved that a reactor design can be fully decommissioned, I don't think we should build more. That's not a problem that I want to dump on their shoulders.

What sort of world will your grandchildren inherit if we don’t invest in nuclear? What happens if the mystery renewable energy storage and carbon scrubbing technologies never materialize? What happens if the climate scientists are right about the increasing droughts and floods and the knock-on effects to food supplies and so on? By comparison the risk of nuclear is negligible.
> if we don’t invest in nuclear?

That depends. The trajectory we're on is one of unrestrained economic growth. In that scenario, demand for power will only increase. Growth has many other harmful effects, including ever-greater quantities of plastic waste, and depletion of natural resources like fish stocks and rainforests.

I have no idea how to tame growth. Most governments put growth near the top of their objectives. But I think it's growth that will blight my grandchildren's lives, not a shortage of electricity.

Am I missing something? Why is decommissioning nuclear power plants the problem here? There are plenty of nuclear power plants that has been decommissioned. So this is nothing new.
In the UK, several nukes have been taken out of service; none has been "decommissioned", in the sense that the site can be re-used, people can live and work there. The first nuclear power plant in the UK was built in 1956, and the current plan is that decommissioning will be completed by 2104; I will be long gone. Until then, the site will be closed to the public.

Perhaps you know of nuclear power plants elsewhere that have been fully decommissioned. I don't, but there is an infinite number of things I don't know, and I would love to be surprised.
