It should be remembered, of course, that ocean-going nuclear power plants have been built and proven extensively across the world, going back 50 years. Yes, I know the Russians don't exactly the same glowing safety record as say, the US does. They have not had quite the financial resources, politica...

A poorly designed containment dome, a weakened containment dome, malfeasance, sufficient pressure... there are a host of choices. Sufficient pressure? It's engineered to withstand the pressure - the maximum possible pressure it could encounter. Do you have any idea of how systems like this are engi...

No, for starters stainless steel is merely corrosion resistant it is not corrosion proof. Further it is significantly weaker then carbon steel. It would not be corroded through by the boric acid solution involved. The core gets too hot, pressure builds up, breaks the pressure vessel, radioactive st...

So, what are we left with? One non-event which showed how well Western reactors prevent meltdowns, and a number of accidental leakages (I believe the leakages have been getting less frequent per plant as time goes on). The number of deaths due to accidental leakages is tiny compared to the number o...

So, your girlfriend/boyfriend thought π≈3

So, your girlfriend/boyfriend thinks, somehow, π≈3.19.

Is this acceptable in a relationship, or not?

I think it's pretty bad, next they'll be revealed as a raptor sympathiser.

It's a social issue more than anything else. Nuclear power in Australia is entirely dependent on who wins the next election - it's unfortunate that the two parties I am considering voting for don't support it, because on most other fronts their environmental credentials are reasonably sound. Curren...

Of course it's viable. It's been proven viable across the world for decades.

Renewable energy systems get plenty of subsidies and money in the US, and I think fossils do too. It's not just something exceptional that nuclear gets.

Re: Pi's Utopia

You just killed literature in general, pretty much everything except Maths in fact. Congratulations, Society has collapsed due to lack of education. Let me try and clear this little debate up. If it works, then you can teach it as something that works. If it doesn't work, if it can't be shown scien...

A fair portion of the cost of Yucca Mountain is paid for by the energy companies, and by extension by the consumers of the nuclear-generated electricity. The costs of such a waste facility make up a tiny portion of the overall cost to the consumer of nuclear-generated electricity. A fair portion of ...

In the sense that it goes a good way towards immobilising the heavy metals and stuff in the ash, and tying these materials up in a form where they can't be dispersed into the environment, I think that's certainly far from the worst thing we could be doing with the ash. Some of you might be intereste...

Of course Coal comes out ahead economically, it always has. Coal is cheaper than just about anything else you can consider. And it kills far, far more people than just about any other energy source you care to name. The fly ash from burning the coal contains enough Uranium (and Thorium, plus Radium,...

The main problem I have with nuclear energy is that it still isnt renewable. There's one little objection that I have to "renewable" energy. The entropy of any isolated system, not at equilibrium, tends to increase, reaching a maximum at equilibrium. It follows that, by any sensible liter...

Nuclear energy

This is certainly a serious-business topic, so I figured we might have a thread on it. As a scientist, I contend that nuclear energy has a proven history worldwide as a safe, sustainable source of energy of low environmental intensity, which can readily provide scalable baseload energy needs, and i ...

A Troxler gauge, or moisture/density gauge normally contains a sealed, encapsulated source of about perhaps 7 milliCuries of Caesium-137, and sometimes maybe about 40 milliCuries of a Am-241:Be neutron source - again, a sealed encapsulated source. Media spin aside, how do we get from this - even 50 ...

Natural Fulgerite, of course, is extremely rare, so i can understand why you might want to make it yourself. But Trinitite isn't as rare, it's far more interesting, and prettier, too.
