You can't delete the post, but you could edit out the offensive parts. If you do that, I will remove most of post 175. Or we can just leave that in the past and move on.
Sadly, there is no edit button, just report! It seems 2 day old posts can't be edited. I've reported myself to the moderators and asked them just to delete that post.
I do find the concept of using nuclear to produce diesel fuel interesting, and would like to discuss that further.
Great, although I'm not a chemist. I only collect the papers I find most interesting, but I have good reasons to accept that this is possible.
Regarding breeder reactors, I am not an expert, so even if you could convince me it is OK, that is not what science is about. It is not about persuading the uninformed. It is about persuading those who understand the science well. That is why I mention the study by leading scientists warning about breeder reactors.
My problem with that is I'm not convinced they
are leading scientists because of the paragraph about nuclear explosions. In a world where any group of people can form an online group and co-write a paper together, one has to be very careful about sources. The fact that they said a melt down could cause a nuclear-explosion triggered my alarm bells! They're
not credible! I'm highly suspicious of that article now. I have met many nuclear engineers online, and they would laugh that suggestion out of the room. Sorry, but the entire paper should be thrown out of court as inadmissible evidence. Suggesting a nuclear power plant could cause a nuclear explosion is an outright lie against the laws of physics, a scandalous lie.
So what's the real difference between low- and high-enriched uranium? Why couldn't low-enriched uranium create an explosion that's just not quite as severe as its high-enriched equivalent? For that, we must turn to another term that is frequently mentioned but infrequently understood, and that's critical mass. The term simply means that there's enough fissile material present to sustain a chain reaction, and a supercritical mass is where enough material is present for the fission rate to increase.
Although mass is obviously an important factor here - hence the name - it's possible to alter the point of criticality by varying other attributes of the material, including shape and density.
A nuclear weapon is designed to release all its energy in one incredibly destructive blast, which means the material wants to be as densely packed with fissile material as possible, and the material should be packed into as homogeneous a sphere as possible.
That's absolutely nothing like the design of reactor cores, which is meant to produce a steady, controlled release of energy, and even the sort of energy buildup needed to produce a meltdown can't ever attain the speed and intensity needed for an explosive nuclear energy release. T
he geometric arrangement of uranium-235 in a nuclear reactor is just fundamentally not conducive to the spherical arrangement needed for an explosive chain reaction, and the amount of non-fissile uranium-238 in reactor-grade uranium also stops any runaway reactions dead in their tracks.
Why A Nuclear Reactor Will Never Become A Bomb
Summation:
1. Uranium is not a natural explosive.
2. Reactor fuels are 30-90 times too dilute in fissionable isotopes to make a bomb.
3. It is impossible for any power plant reactor to experience a nuclear explosion.
4. Walt Disney's "ping pong balls" demonstration of a chain reaction only works for bombs.
Nuclear Chain Reaction | Bomb Grade Uranium | Natural Uranium
To prove it is viable, that is the case one needs to refute. Finding someone on the Internet you can convince is not the same as making a case that would pass peer review.
I'm not sure what you mean here: the paper you cite is simply not credible precisely because it claimed that a nuclear power plant can cause a nuclear explosion. I will not convince those authors of anything, because they're either:-
1. intentionally lying,
2. or don't understand the science enough themselves for their opinion to matter in the first place!
All I can tell you is that the human race already has 400 breeder reactor years (reactors multiplied by the number of years they were run) experience with breeder reactors. Some of them are not my favourite configurations, but they are being built. Here's my quick summary of what's happening in the 2 main categories of breeder reactor. Don't feel you have to read all the wiki's, just read slowly through my descriptions and summaries to get the big picture.
Breeder reactors burn the longer lived
actinides in nuclear waste, eventually burning the nuclear waste down to the
fission products which only stay
hot for 300 years.
Breeder reactor - Wikipedia
We have over 400 reactor years experience with the fast-reactor category alone, and some nations already have them in operation.
Fast Neutron Reactors | FBR - World Nuclear Association
There are two main categories of breeder reactor.
CATEGORY ONE: Fast Neutron reactors.
Fast-neutron reactor - Wikipedia
Russia had the old BN-350, and then built the Bn-600. Note: the Japanese paid Russia a billion for the technical specs on their old BN-600, and “The operation of the reactor is an international study in progress; Russia, France, Japan, and the United Kingdom currently participate.”
BN-600 reactor - Wikipedia
They just opened the BN-800 (and sold the plans to China).
BN-800 reactor - Wikipedia
They are building 11 new normal reactors over the next few years, including 2 whopping great BN-1200 breeder reactors! They already have plans to retrofit the fuel supply to burn nuclear waste from other plants.
Russia to build 11 new nuclear reactors by 2030
G.E. have the PRISM ready for commercial prototype testing (as the original proof-of-concept testing was done decades ago in the EBR2). They are basically ready to deploy in the first country that will let them.
PRISM (reactor) - Wikipedia
China will mass produce breeder nukes cheaper than coal in just 5 years!
China seriously looking at supercritical water cooled reactors – they could be low cost enough to get China to stop building new coal starting in 2025 | NextBigFuture.com
CATEGORY TWO: Thermal (slow neutron) reactors run hotter
My favourite thermal reactor is the Liquid Fluoride Thorium Reactor which CANNOT 'melt down', as it is already a liquid! See China's plans!
China-U.S. Nuclear Collaboration, Though Controversial, Moves Ahead
Watch this 5 minute video if you have time. It cannot melt down, already a liquid, it produces enough heat to run fertiliser, mining, smelting, desalination and other industrial process
and produce electricity as a side-product!
ENOUGH FUEL?
America has enough nuclear waste to run her for 1,000 years and this has been estimated to be worth $30 TRILLION dollars!
The Integral Fast Reactor – Summary for Policy Makers
The United Kingdom has enough waste to run her for 500 years.
New generation of nuclear reactors could consume radioactive waste as fuel
When we finally run out of today’s nuclear waste to burn in 500 years my guess is we might not even need fission reactors any more, as we might have 24 hour reliable baseload space-based solar or even fusion power by then. But if we do still need to use IFR’s and LFTR’s, what then? Uranium from seawater is 'renewable' in the sense that erosion constantly tops up the uranium particles floating in the ocean, 3 times faster than we could use it. It will last us a billion years.
WASTE? Once the actinides are burned out, the fission products only stay 'hot' for 300 years. Just vitrify it into waterproof ceramic blocks, and store in carpark depth bunkers. Done. Trivial. Not an issue!
