I fully agree that nuclear SHOULD have been part of the solution. I disagree that it should now be part of it. We have lost too much knowledge regarding nuclear power to lack of investment. We no longer have time to rebuild that to get it online. Hopefully it can become part of the solution eventually, but 10-20 years is now far too long to wait.
In fairness, the only thing many people will lack is water. It’s not an exclusive stash, but in addition to what’s in your cupboards.
You can get 10L or 25L quite cheaply. 1 should do per person, maybe with an extra for cooking. Or just grab some big bottles of water.
A hand cranked flashlight, candles and lighter are all a must anyhow, for a power cut. It might also be worth having a cheap camping stove tucked away.
Food wise. It’s just a big bag of pasta or rice, along with some cans/jars to make it pleasant to eat. Throw in some hiking snack bars and you’re sorted.
