Not to mention that since these countries will be using fuel from an international pool, there is no reason why that fuel can't be used in Gen IV reactors located in other countries. Sweden for example has sent some "spent" fuel to France for use in the Phenix reactors (I forget which one of the two).

This creates a problem though. If they can turn the energy tools in to weapons, well then you can end up having nuclear arms in the hands of people who would use them out of spite, ignorance, etc

These countries will be subject to stringent control through the IAEA safeguards program. Which means this: any hint of an enrichment facility being constructed, and the country is completely cut off from any outside help, be it nuclear physics education or uranium trading etc.

An enrichment facility capable of producing anything remotely usable for weapons is a hell of a lot harder to build than a facility used for creating nuclear fuel. The whole point of this is to keep these countries from building enrichment facilities at all.

"Beta-rays" means electrons and positrons. These are light charged particles. Neutrons are heavy and neutral.

That being said, being in a high neutron flux for any length of time can be harmful to a human.

Of course this is handled with shielding. And I believe in any serious fusion reactor breeder blankets (not sure which material) are put in place, which absorb neutrons to generate lithium. Lithium is required for the D-T reaction.
Since I'm no expert in fusion I'm sure someone else can give a more precise answer.

Submission + - Swedish nuclear ban lifted (nuclearpoweryesplease.org) 1

DrKnark writes: After 30 years (since the public vote in 1980) the ban on nuclear power in Sweden has been lifted. The decision means a maximum of 10 reactors in Sweden will be allowed, meaning old ones have to be shut down to start a new reactor. No government funds will be allowed to be used to subsidize any nuclear power endeavors.
However, the opposing parties have promised to reverse the decision if they gain power in the September election.

Submission + - Problem Solving: Street Smart or Book Smart ? (businessinsider.com)

abhijitkar1962 writes: Martin Zwilling tells us to be street smart rather than book smart while attempting to solve problems. Where as Rockt, quoting Aristotle and also making it clear how frustrating is it for a book smart to watch street smart people easily adapting to challenging situations, insists that ideally it should a combination of both, at optimum level.

Submission + - AMD Drives Cost Out of Pro Graphics Cards (hothardware.com) 2

MojoKid writes: "Workstation "pro" graphics cards are validated versions of standard desktop graphics cards but with specialized drivers for compatibility with the latest 3D rendering and CAD tools on the market. Typically these cards sell for a massive premium over their desktop counterparts but with very little, if any, difference in hardware. AMD has bolstered their ATI lineup with five different FirePro models recently at various price points and performance levels. In addition to the top of the line V8800, the new lineup consists of the high-end V7800, the mid-range V5800, an entry-level V4800, and the almost ridiculously affordable V3800. This detailed review covers performance and features of three of the more affordable cards in the FirePro lineup. It's safe to say that AMD is driving cost out of pro graphics finally and in some cases, prices have actually hit parity with standard desktop models."

Submission + - Thailand shuts down 43,000 more websites (bangkokpost.com)

An anonymous reader writes: Bangkok Post reports that the Thai government has now shut down over 43,000 websites deemed defamatory to the royal institution. Thai ISP's are warned to cooperate 'voluntarily' or lose their license. This is in addition to 17,000+ that were recently blocked for 'national security', including both Facebook and Twitter accounts.

Submission + - Being Wrong is What Makes Humans Smart 2

Hugh Pickens writes: "Kathryn Schulz has an interesting article in the Boston Globe about how the more scientists understand about cognitive functioning, the more it becomes clear that our capacity to make mistakes is utterly inextricable from what makes the human brain so swift, adaptable, and intelligent and recognize that human fallibility is part and parcel of humans' brilliance. Neuroscientists increasingly think that inductive reasoning undergirds virtually all of human cognition — the decisions you make every day, as well as how you learned almost everything you know about the world and that we use inductive reasoning to learn language, organize the world into meaningful categories, and grasp the relationship between cause and effect in the physical, biological, and psychological realms. "The distinctive thing about inductive reasoning is that it generates conclusions that aren’t necessarily true. They are, instead, probabilistically true — which means they are possibly false," writes Schulz. "Because we reason inductively, we will sometimes get things wrong." Schulz recommends that we respond to the mistakes (or putative mistakes) of those around us with empathy and generosity and demand that our business and political leaders acknowledge and redress their errors rather than ignoring or denying them. "Once we recognize that we do not err out of laziness, stupidity, or evil intent, we can liberate ourselves from the impossible burden of trying to be permanently right. We can take seriously the proposition that we could be in error, without deeming ourselves idiotic or unworthy.""

Comment Re:Fusion Reactor... Crisis?! (Score 1) 470

I just want to make a semi-related comment on this topic. Because of the natural content of radioactive isotopes in coal, coal fired plants actually release significant amounts of radioactive material into the atmosphere during normal operation. Not to mention the other nasty stuff that comes from them. Obviously with nuclear the dangerous stuff is kept contained and in solid form.

"These products emit low-level radiation. But because of regulatory differences, coal-fired power plants are allowed to release quantities of radioactive material that would provoke enormous public outcry if such amounts were released from nuclear facilities" - Radioactivity from burning coal - Brief Article

The sources talking about the relative amounts I have found seem to be biased either one way or the other, but this quote is certainly relevant. There is a fear of anything nuclear, but radiation from other sources seem to be accepted.

Mod me off-topic if you like :)

Just a few corrections. "Huge tokamak reactors" have been built before and are currently operated (see for example Joint European Torus).
Secondly, you say that as if both confinement techniques require tokamaks. This is not so. Inertial confinement makes use of lasers for the confinement, and requires no tokamak. I am not saying this is better, just that it has very different requirements.
