Finally: 'SAFE' nuclear power plants ARE on the horizon!
All life exists primarily because of 'nuclear energy.' But up until very recently I have never been a proponent of nuclear power on the surface of terra ferma as it was quite apparent it was way too dangerous and that we have no effective means to cope with the aftermath. Till now, the ONLY safe place for it is where it already exists: in space or deep within the mantle of the earth.
Early proponents of nuclear energy power plants made claims that the staggering costs of building them in the first place would be offset by their efficiency and longevity that they would still be economical. In practice this most definitely has not proven to be the case. The radioactivity erodes the metals so that they are only good for about 20 ~ 25 years and then they are even more of a nightmare to dispose of all the irradiated materials on top off all of the VERY dangerous radioactive fuel, most of which the majority of the radioactive energy still remains in these materials .
A couple of years ago Scientific American had a good article on the next generation of fissionable power plants and differ VERY significantly to all previous nuclear types. It is a slow (or fast?) neutron breeder reactor. Unlike current operational plants which are only able to utilize less than 5% of the energy in radioactive materials and then leave us with no possible realistic safe methods of disposing this very dangerous highly radioactive waste, along with all of the materials from decommissioned plants. Weapons grade materials can also be produced from this spent nuclear fuel. Alas I haven't been able to find it either online or in my collection which mostly has been donated to hospitals.
This next generation nuclear power plant utilizes OVER 95% of the radioactive energy available in the fuel: it is recycled numerous times until almost ALL of the radioactive material is depleted. Leaving very little nuclear waste in comparison which only has to be stored for a few hundred years which might be realistic, as opposed to hundreds of thousands of years or even millions of years which is totally unrealistic.
The radioactive fuel, including it's by products, can NOT be utilized to make weapons grade nuclear material in these new generation of nuclear reactors! Hardly an insignificant fact.
Also these nuclear reactors would be buried in the ground with the top open at about ground level. If a major catastrophic failure occurs, the coolant will be released into the underground installation and which will flood the entire thing which will bring about cessation of the nuclear reactions.
Thus IF the current spent radioactive material left over from previous generations of nuclear power plants that is now a nightmare with no way to realistically deal with it; IF this highly radioactive material can be used in this new generation of safe nuclear power plants we should KEEP IT and store it properly, safely and effectively and use it in these new nuclear power plants.
If not we should build big 'air cannons' which are basically steel lined wells into the earth and come up with nose cones and stabilizing fins that are easily attached to 45 gallon drums and once a day when the earth is in the right position fire them off into the sun. Only after rigorous testing and confirmation of complete safety of course.
As most that are familiar with such matters will likewise be aware of, realistic Fusion power generation which has been under development for close to a century is getting to the point that it will be possible to have fusion power plants in the foreseeable future which will bring unlimited, safe, clean power for all.
Given our present very urgent dire circumstances, ALL current resources being poured into things that are not vital priorities to our immediate survival such as space exploration and preferably nuclear weapons and everything else that is not directly related to saving life on our planet should ALL be focused on this vital cause that is already at the crisis point and is transpiring at a rate that requires nothing short of an all out global emergency that should be focused on these priorities. We are already plummeting into the endless infinite void of the abyss and we need a total and complete unified global 'mobilization' and action on a scale such as never before. For we are facing a crisis on a scale , magnitude and seriousness unlike anything humanity has EVERY faced before!
I am NOT against space exploration or other sciences. On the contrary, I firmly believe in them. But this global ecological crisis IS a matter of vital priorities. Realistically 'space exploration' is something that will take thousands of years to effectively bring about. IF we want to even be around long enough to undertake such ventures successfully, then we had better start concentrating on saving life on our home, including ourselves.
Though many in 'advanced technological societies' have the delusion that we are no longer dependant on the 'food chain' for our survival and are beyond this; we most definitely are not. Anyone that thinks that we are total and complete 'masters of our domain' only need to take into account the forces of nature that can and do wreck devastation upon us regularly with significant consequences of which we have virtually no power or control over. On the contrary it is very apparent that we are anything but. IF we want to have a home to live on, then we had better start taking MUCH better care of it NOW as we HAVE poisoned our entire world for all life including our own. This is not even taking into account the consequences of humanity's activates that are changing our climate at a rate that makes the period that the dinosaurs along with 90% of the rest of life on our planet extinct over a period of ~ 250,000 years. Scientists say this was so rapid and so radical that it was 'revolution' and not 'evolution'. The rate that life is being extinguished on our planet now from human activates makes the previous period of mass extinctions look like the 'Garden of Eden' in comparison to the rate life on our planet is becoming extinct in a VERY much shorter period of time from humanities activates. Regardless of if you take it from approximately 10,000 years ago with the advent of agriculture that allowed us to settle and stay in one place and thus begin to build up more complex civilizations with ever increasing technological complexity or if you measure it from just a few short centuries ago with the advent of the industrial revolution.
As Carl Sagan said: 'It is very likely that 1/3 to 2/3 of the worlds that life evolves to the point where it becomes sentient and self aware and unlocks the secrets of nature don't survive it. Either from poisoning their entire planet and all of it's ecosystems as we have done; or from the incredibly powerful weapons that they can and do develop and use, or both. We HAVE totally and completely poisoned our home, and most definitely have the weapons of mass destruction that can radically increase the rate of our own destruction. As most are aware if there was a nuclear war, that even for the small percentage that survived the actual attacks, that there would be very little left to survive on and everything would be poisoned and contaminated by radioactivity. The figures I have heard spoken of are that there HAVE been over 10,000 'nuclear bomb 'tests'' since the first one was set exploded less than a mere century ago! Just as if there had been a 'nuclear war!' One sixth of what used to be the largest country in the world: the USSR, is so contaminated by radioactivity that for all intents and purposes it is uninhabitable and will be fore 'eternity' on a human time scale.
The ''Genie' is out of the bottle', Pandora is out of here box and there is NO WAY to put them back in!
To borrow a phrase from 'Midnight Oil': "How can you sleep when your beds are burning?"
Though it is not as immediately or readily apparent to most as one's own home being on fire is, our ENTIRE home IS in such a crisis and needs to be dealt with as such.
We need to very rapidly alter our priorities if we are to have ANY chance whatsoever of saving some, if not ALL, life on our planet from being totally and completely extinguished in a VERY short period of time on a geological or cosmological time scale; or even a 'human' time scale for that matter at the rate that this is currently transpiring at and is accelerating at an ever increasing pace!
If humanity on our planet lasts long enough that it even merits being noted on a geological or cosmological timeline, it will likely only because of what a powerful example we are as failures and how 'NOT to do it!'
We are OUT of TIME! If we are to stand any chance at all of surviving this, we ALL need to 'mobilize' NOW on a scale unlike anything prior to this. As we have never faced a danger anywhere even close to what we are already in. If we want to leave a world where life is even possible for our children, grandchildren and future generations; then we need an all out comprehensive, multifaceted global action plan in place. Operating and acting on an 'emergency crisis' level; as that is what we are most assuredly are in!
For those that believe that there will be an apocalypse in our time, and even more for those that don't believe in it at all: we ALL need to WAKE UP and act accordingly because it IS upon us and we need to respond accordingly.
