[Various] Japan Nuclear Emergency - Continuous Coverage of Damage and Radiation Risks - Page 268

The whole explosion theory is a pile of .... yeah.

Nuclear power plant fuel is enriched (or purified) to 3%. Nuclear weapons fuel is enriched to something like 97%.

There is no way that power plant fuel can explode like weapons fuel. It is purposefully enriched to ONLY 3% to make it more easily controllable.

^question. Not to stray off topic, but if this was the case, why do we freak out when we hear of another country enriching low grade uranium only for nuclear power plants? Like when Iran says they are enriching it only for nuclear fuel, then it would not be possible to make a nuclear bomb out of it???

because if they are enriching for fuel, they can enrich for weapons. We don't know how much they're enriching the uranium.

According to your argument humanity does not understand garbage because they cannot get rid of it while leaving no trace.

The kind of physics involved in this is not even close to the frontlines of physics research. Understanding nuclear reactions is basic physics.

Since you seem interested in radiation here it is:

Alpha radiation: Simply a helium nucleus. Two protons, two neutrons, and no electrons. For this reason since it has a large positive charge it will stick to practically any surface it comes across without doing any significant damage. It cannot penetrate more then a piece of paper.

Beta radiation: A free electron. This has a negative charge but since it is so much lighter then an alpha particle it can travel much faster and penetrate a bit deeper then an alpha ray, it is dangerous only if a substance which releases beta rays is ingested.

Gamma radiation (also known as photon radiation): Basically a photon with a high frequency and short wavelength. Because of the nature of the photon it can penetrate extremely deep through surfaces, requiring a very very very thick wall to capture and stop it.

Neutron radiation: A free neutron. Because it is a single neutron it can move faster then an alpha ray but slower then a beta or gamma ray. Since it has no charge the only way it can be stopped is by a direct collision with the nucleus of an atom. The problem is that if a nucleus were a baseball, the electron shell of an atom would be the size of the baseball field. So much of an atom is empty space that a neutron can easily pass through. It can penetrate extremely far into a surface. But when they do get stopped and absorbed into an atom it can make that atom radioactive.

Different unstable elements will release different types of radiation.
Not to be an ass but in that case whats radioactive mean?

Politicians also tend to get riled up easily.

Ok mr nuclear scientist. How many neutron bursts did reactor 1 put out on it's meltdown and what kind of fuel you need to do that.

reactor 3 has been confirmed to be powered by plutonium as it is a MOX reactor and that is the one that is the most dangerous.

A nuclear explosion is indeed a physical impossibility.

There is not enough fuel in any of these reactors for a critical mass of U235 to form. They are only enriched to a few percent, and at those levels, you would need thousands of kilograms of fuel to collect in a favorable shape and be held there for a long enough period of time without melting through it's container, boiling off, or otherwise becoming sub-critical.

U235 is not going to separate from the other isotopes in the fuel on it's own. If it were so easy, countries wouldn't need to spend billions on the equipment needed to enrich it.

This is true, but it's no more possible for it to go critical.

Isn't this common knowledge by now? They have been saying this since day 1 and people are still like "OMG it has MOX fuel!"
