A friend of mine gave me this link. Does anyone know if this for real?

It is for real. Whether it will perform as hyped remains to be seen. It does not appear to be licensed yet. Toshiba has a similar nuclear "battery" the 4S reactor. Hyperion, apparently, likes to refer to it as a battery rather than a reactor and it suggests that it is a chemical device. It is, however, a nuclear reactor that produces heat from nuclear reactions. It does not produce heat by chemical reactions.wildman said:A friend of mine gave me this link.

There is plenty of U for thousands of years if we had the technology to use 100% of it instead of the 1% that current reactors use. See the recent https://www.physicsforums.com/showthread.php?t=216571"Enthalpy said:Where do you find enough uranium for everybody? Uranium deposits (known and estimated) have far less total energy contents than coal, gas and even oil. Uranium reactors are not a global solution, they may be one for a handful countries.
Enthalpy said:How do you protect the produced plutonium against theft? A government is willing to pay 10,000 people for years to build bombs. Attacking a few plants like this one is far too easy. Their plutonium contents is similar to any other reactor size. Shall users pay for 100s permanent troops to guard them? And for 10,000 police when removing spent fuel?
Don't tell me about military grade. North Korea didn't need military grade, and their 500t explosion is undesirable. Worse, nuclear engineers would know how to make efficient bombs with waste grade plutonium.
And imagine converting this plant into a dirty bomb. Dig a tunnel, put a chemical explosive, ignite, done. Those seeking surgical precision may first transport the plant where they want.

The Russian BN-600 fast breeder reactor is still operating and has support from US and EU nations.Enthalpy said:Enough uranium: Breeders are abandoned now. Every single now, though there were several attempts worldwide. And there are excellent reasons!
Yes, proliferation IS a huge risk with a breeder - or rather, is certain. Its plutonium load is directly usable for a bomb. And if you don't want to explode the full plutonium load of the bomb, then it's easy to build one.
It definitely makes a proliferation difference whether a state must produce the nuclear fuel for a bomb or can pick it from a reactor. That's the whole point of non-proliferation treaty and fuel control. North Korea, India, Pakistan, Argentina, Brazil, Libya, Iraq got the fuel from power plants for their bomb attempts.
The only breeder that wouldn't proliferate is Carlo Rubbia's thorium scheme, but it's an incomplete proof-of-concept up to now, as building the powerful accelerator needs unclear technology, so it's far even from a prototype.
Nonsense.Enthalpy said:Plutonium theft: again, states are willing to pay 10,000 people for years to get nuclear bombs. Stealing a few tonnes is easy, underground as well - or when the used reactor is being removed - and doesn't even need to go unnoticed.

Enthalpy,Enthalpy said:[
There are breeders (in Russia, yes) that use thorium as a fertile element and highly enriched uranium, or preferably plutonium, as a fissile one. However, they don't produce significantly more new fissile material than they consume Pu or 235U, so they can't take advantage of the important thorium deposits. It's rather a clever way of destroying excessive 235U or 239Pu from recycled weapons.
Enthalpy,Enthalpy said:Extracting plutonium IS easy because plutonium has distinct chemical properties. This is true from spent uranium fuel, and even easier for plutonium fuel as in a breeder. It doesn't need isotopic separation but just chemical operations. This is exactly what North Korea did, because it is easier.
Enthalpy said:
Thorium breeder: I wrote about Carlo Rubbia's scheme which does need an accelerator - this is what makes it distinct. If you pretend to know nuclear technology, you can't ignore this. Rather a matter of bad faith.
Morbius said:Although it is true that chemical separation is
comparitively less difficult than isotopic separation - it is by no means "EASY". In fact, the
chemical processes that are used to separate Plutonium will flip the valence state about 19 times.
Only Plutonium can run that gamut of valence changes.
Candyman,theCandyman said:What does that mean? I don't know much about chemical seperation.
Yes you could steal one and drive it into the middle of a city, wrap explosives around it and blow it up.Just curious though... couldn't this thing be used to make a dirty bomb?

vanesch,vanesch said:In fact, Rubbia's reactor was a solution in quest for a problem. Rubbia, brilliant as he is, was an elementary particle physicist (as I am btw, but we don't play in the same team ) and brilliant at that (Nobel prize and everything). However, he "solved" a problem that didn't need a solution: he must have thought that the principal problem of a nuclear reactor was to shut it down when it failed. He must not have heard of passive safety I guess. So his proposal does solve that: when the accelerator is stopped, the chain reaction stops. True.
vanesch,vanesch said:What is the true problem is to keep removing heat from decay of fission products just after the nuclear chain reaction stops, and to confine all that mess inside a containment building. The main problem is not to stop the reaction, the main problem is to cool, and to contain.
Well, those aspects are not influenced positively by the presence of an accelerator (and the hole that is needed in the reactor building to bring in the beam and everything).
mheslep said:It may indeed be over hyped in the media, but fatalities are not necessarily the problem from dirty bombs per the serious literature - there would likely be a severe economic loss from the cleanup. The literature commonly uses the Port of Long Beach for its scenario: Evacuation - $4 billion for 400,000 people. Temporary operation shutdown, economic losses - several hundred million $. Cleanup - $1 trillion for the cleanup if EPAs 15 mrem decontamination standard is used which likely means abandonment or demolition, $billions if a less stringent one rem standard is used. Also, Muller uses a 1500 curie attack in his TR article, a single spent fuel rod could yield 2,000,000 curies.

Yes. I wonder how the US standard compares abroad?vanesch said:So what's making this overly expensive is the severe decontamination rule.
15 mrem = 0.15 mSv = less than 1/20th of the natural background dose...
Yes, Hyperion Power Generation is a real company that was founded in 2007. It is headquartered in Denver, Colorado and has since been acquired by Gen4 Energy in 2011.
Hyperion Power Generation uses small modular reactors (SMRs) that are based on the concept of nuclear fission. These reactors use uranium hydride as fuel and are designed to be compact, safe, and efficient.
Hyperion Power Generation's SMRs are significantly smaller in size compared to traditional nuclear power plants, making them more suitable for smaller communities or remote locations. They also have a lower risk of accidents and produce less radioactive waste.
While nuclear power is not considered a renewable energy source, Hyperion Power Generation's SMRs have a longer lifespan and produce less carbon emissions compared to traditional fossil fuel power plants. However, they do produce nuclear waste that must be properly managed.
Hyperion Power Generation's SMRs are designed with safety as a top priority. The reactors use passive safety features, such as natural convection cooling, to prevent accidents. They also have multiple layers of containment and are designed to withstand natural disasters. However, as with any nuclear technology, proper safety protocols must be followed to ensure its safe operation.
