US Plans "Disposable" Nuclear Batteries 297
holy_calamity writes "A US government program is in the works to design small nuclear reactors for use by developing countries. The work continues despite fears about security and nuclear proliferation. Plans include having reactors supplied with fuel by the US and other trusted nations, or to build reactors with their whole lifetime of fuel packaged securely inside — like a giant non-user replaceable radioactive battery.'

And Toshiba's not the only game in town as far as micro-reactors go. Why would the government spend a boatload to develop something that already exists commercially? Why not just allow countries to select the best commercial design that fits them and ease the regulatory barriers to permit easier US fueling of self-contained sub-50 megawatt reactors? Seems like the AEC is just caught flatfooted in response to new technology, that's all -- no need to develop anything, just rework the regulations to take into account new technologies.

It has been happening anyway and really is not related to devices like this. We don't have to worry about the Iranians wanting them either. Iran would also most likely be able to do something as good or better by this point since nuclear power research in the USA stalled long ago and is far behind the South African (pebble bed), Chinese and Russian technology that is available to the Iranians.

The power consumption of devices is really important to me. For idealistic reasons I buy devices featuring high energy efficiency. Plus there is an economic dimension: In my country one kWh costs around $0.31 and one gallon is aroung $7.5. I must admit that the current dollar/euro ratio inflates these prices, but even if the exchange ratio was 1.30 the numbers would still look rather high. But even when I give preference to low-power devices I have no doubt that anything saved by me (and the western world in general) will be compensated by higher demand in emerging markets.
Btw: A high share of the prices mentioned above go into subvention of biofuel, wind- and solar-power. But even with high subventions the market share of regenerative energies is around 5% over here. In my very greenish opinion the best way to archive sustainability is the following: Tax energy consumption, but use the money coming from it for something else than subvention. This will make sure that demand is reduced on the customer side. On the production side legislation should regulate: Install a emission trading system like in Europe (but better) and sign international treaties like the Kyoto protocol. Producers could still use coal plants, but the economic benefit would strongly favor other sources of energy. I strongly believe that any other system will result in billions spend in nonsense.

the obvious solution, is to not use a pump that requires a seal, or to design a seal that doesn't react to liquid sodium.
but it caused an unshielded test reactor to melt down, albeit in a desert, but it was the worst atomic accident that the government doesn't want people to remember.

David Roodman, from the CGD, attempts to adjust the aid numbers by including subjective factors PDF formatted document:
* Quality of recipient governance as well as poverty;
* Penalizing tying of aid;
* Handling reverse flows (debt service) in a consistent way;
* Penalizes project proliferation (overloading recipient governments with the administrative burden of many small aid projects);
* and rewards tax policies that encourage private charitable giving to developing countries.
In doing so, the results (using 2002 data, which was latest available at that time) produced:"
With all due respect, your link uses the above factors to skew the numbers. The fact that they openly admit the numbers are subjective destroys their usefulness. I could skew the numbers any way I liked if you let me pick the variables.
"but those studies invariably count things like immigrants sending money home to their family"
Why wouldn't that be counted? Dismissing that out of hand is just as irresponsible as using "subjective" numbers to skew the data.
"As far as real aid goes, 90% of the money genuinely donated by generous Americans never makes it out of the country"
I'd like to see your source for this, if one exists.
"This meme is simply not true"
Well, if that is so you haven't proven it. If you thought a "reassessment" using "subjective" numbers was enough to do that, you need to "reassess" your thought process.
