Yes, you rightly highlight the problem of ageing nuclear reactors all around the world.
How are all these old reactors going to be de-commissioned?
Where will the thousands of tons of contaminated reactor materials - let alone spent fuel rods go and be stored safely for hundreds if not thousands of years?
When accidents happen - as they invariably do, who will insure these reactors? Fukushima tells us that it is always the tax payer that bears the cost if things going wrong.
No insurer has the financial capacity to finance a serious nuclear accident.
The solution of the nuclear industry to dealing with contaminated radioactive water is. ...dilution?!?
You also highlight another interesting thing about nuclear reactors, when you talk about the old "Mini Morris" vs the modern "Aston Martin" - unlike any other energy technology nuclear energy suffers from a negative learning curve. Usually, over time, things like wind and solar energy can be installed quicker and cheaper. In stark contrast, over time, nuclear reactors have become more expensive and take longer to build.
In the past, crazy greenies would also mention that nuclear reactors could potentially be used as a weapon during times of conflict. This hypothetical scenario was often dismissed as unrealistic hyperbole ... until Russia started putting the explosives onto the Zaporizhizhia nuclear power plant in Ukraine.
Until now, nuclear energy supplies a small percentage of global energy needs. However, if it were to proliferate into a major energy source, it would not only be installed in rich technologically advanced regions, but find itself in countries that are geologically and politically less stable.
Corruption and terrorism could see nuclear material fall into the wrong hands. But then, that is only unrealistic crazy greenie anti-nuclear hyperbole!
Renewable energy today might be a far way from being perfectly sustainable, but I am fairly confident that what we see today are only the first iterations in the development of truly sustainable renewable energy.
Our highest priority must be to accelerate in that direction.
Nuclear energy is merely a distraction created by people with vested interest ...and that includes the fossil fuel industry. Nuclear energy is merely a delaying tactic for mankind to shift to sustainable energy.
