    Now just between me and the people who actually do know "fuck-all" about physics, it is pretty damn humorous that the metric system, which I often hear fans bragging about how you don't use fractions, is measured to the highest available accuracy.......

    By a fraction. Howbow dah?

    Well, that's a little funny. But us in SI-land at least have a definition. What I find more funny is that you in imperial land don't even have a definition. What I find funnier is that imperial units are defined in terms of the relevant SI unit. E.g. " The international avoirdupois pound is equal to exactly 453.59237 grams." Now, that's funny.

    And it doesn't matter if 0C is distilled or salt water or whatever. It's much more convenient to know that if I'm close to 0C when driving I better watch out for ice, than "thirty something". The approximate freezing point of water makes practical sense in a lot of contexts, worthy of a "special" number. (Most everyday thermometers aren't accurate to more than +/- 1C anyway (half that if you're lucky), so the exact definition in the physics lab isn't that important for most cases anyway.)

    The problem with a "cost" analysis is that you're comparing apples and oranges. If it was only a matter of cost/kWh then solar and wind would be fine and dandy. There'd be no question that that would be the way to go.

    Unfortunately running on unreliable sources like solar and wind doesn't work as our use of the grid presumes stability of delivery and being able to follow load. We're already having problems in Europe due to wind having to be dumped at negative cost on the market (i.e. they produce more wind than we can use); wind being especially problematic in that the power delivered varies as the cube of wind speed. You only get nominal power in a very narrow range of wind speeds.

    Now, of course, these aren't problems that are insurmountable, but it would take a substantial change of the grid with large scale long range interconnects (to even out differences in wind/sun) and storage (to further even out e.g. day/night). These costs are substantial, and must be factored in when talking wind/solar.

    As it stands now we have the figures already. Sweden with a hydro+nuclar mix where we've switched as much to electricity as possible we emit roughly half as much CO2 per capital as the "forerunner" Germany. If we factor in industry production we're even better of. Germany's getting rid of nuclear means in actual fact that they have tied themselves to lignite coal (the largest source of particulate pollution in Sweden is actually coal power refuse blowing here from Germany and Poland). They pay about three times as much for electricity as we do, and hence do not use it if it can be avoided. They use fossil fuel for as much as is practical. (I.e. heating their houses etc.) Same is true of the Denmark to a large extent.

    But with the current government here, they'll finish off our nuclear in short order, and we'll be changing our energy mix to the same dirty mix as Germany in short order. Don't you worry... All in the name of becoming "green". It's enough to make you bloody weep.

(We're still suffering from the technological choices made way back when, as they're not compatible with the rest of the grid).

    Now, that wouldn't be a problem as our uranium is more centrally located, and Norwegian Thorium is the same. (They also have more electricity).

There's absolutely nothing stopping the siting of a small reactor so close to the mine that transmission won't be a problem.

    Witness instead the IPCC figures. They also state that which "stormsmith" doesn't, namely that you don't get much CO2 from nuclear LCAs unless you assume that the mining and especially the enrichment centrifuges run on coal powered electricity. Now, that may be "true" today, depending on the energy mix, but since nuclear power produce electricity, and there's nothing stopping the use of nuclear electricity in either mining or enrichment, that's a bit disingenuous. By that token wind and solar emit quite a bit of CO2 as well.

    So that's a crap analysis, basing any decisions on that sort of reasoning would preclude increasing nuclear in the energy mix, even though that would substantially decrease the CO2 load from nuclear. (Same with "concrete". The reason that's CO2 intensive is heating. There's nothing in principle stopping that heat coming from nuclear or other sources as well.

    Yes, Vattenfall, which is wholly owned by the Swedish government, owns and operates nuclear power (four sites), but they also owns and operates hydroelectric plants, coal fired plants, wind parks, bio powered plants etc. That's why they're a good company to ask, as while they have nuclear in the mix, it's not dominant by any measure, like it would be if you asked the French for example.

    Yes, there's always the risk of bias, but if you exclude everyone with any connection to anything, you'll also exclude anyone who actually has any experience at all. You can't have it both ways.

And with political stability and production then of course the price would come down substantially, the ones you mention are one-offs.
