there is no such thing as a complex system that will never fail. Even if that failure doesn't happen for 100 years the fact is it will happen. Catastrophic floods for example can be 100 year events but they will happen. All mechanical, electrical and chemical plants have the potential for catastrophic failure and some do. Nothing lasts forever. Things wear out and things go wrong. Nothing is built perfectly.
Because of this fact and the awful result when a nuclear plant fails having them increased in number by leaps and bounds is simply madness because while we in the present may very well reap benefits without incident for awhile we will be saddling the future populations of the world with a massive catastrophe. Thinking that technology will be developed in the future to take care of it is foolhardy thinking and a clear demonstration of how we have become delusional in thinking "someone" will always be able to do something.
The climate change has really shot past what feeble attempts governments have been willing to implement to make changes. That problem of human greed and ignorance is one of the most critical problems in trying to employ and control technology that has high risk factors. They will cut corners, refuse to spend money on safety etc. and as we see even when change can be made that can have an immediate impact, like wind and solar, you get greed and ignorance that gets into power politically and puts on the brakes. You cannot risk people cutting corners or refusing to spend the money on safety if you are dealing with systems that carry a very high risk for catastrophic impact when things go wrong.
That is why I said show me a system that will never fail and an absolute never fail safe answer for the waste and I'll be on board. But all systems fail. It is a fact of engineering life. Some sooner and some later and sometimes it's people who fail in their interactions with the system or in it's construction. It is all an undeniable sad fact that we see over and over no matter whether it's a factory, a mill, a foundry, a nuclear plant, a bridge, a ship etc. and the list goes on.
