Large Scale 24/7 Solar Power Plant To Be Built in Nevada
RayTomes writes "The Obama administration has provided a loan guarantee of $737 million to construct the first large-scale solar power plant that stores energy and provides electricity 24 hours a day, 7 days a week."
This solar power project, a heliostat rather than a photovoltaic system, with a molten salt system to store power as heat for times when the sun isn't shining, will be constructed in Nevada and, says the article, is expected to create "600 construction jobs and 45 permanent positions."
What planet are you from? 80%? Complete fiction. Vermont Yankee is very reliable, and had, from 2003-2009, an amazing 92.6% capacity factor. Which gives an employee/Mwatt ratio closer to 1.09, which while still slightly higher than the solar plant, isn't particularly bad.
The source for my claim is an open letter from an Entergy executive, being mirrored at the website of Meredith Angwin, who runs the Yes, Vermont Yankee blog.
For more actual *facts* about VY reliability, see this posting at Yes, VY.
In general, nuclear power plants in the U.S. have had an *industry average* of over 90%. That's not a cherry picked record for an individual plant - that's the *average* capacity factor. There are certainly some things to be worried about Nuclear plants, in terms of risks and costs, but reliability just isn't one of them. Let's stick to real problems, instead of making up fake ones.
As for number of employees per MW at nuclear plants, there is probably room for improvement there, with newer designs. However, I don't see that 650 employees for 620MW seems like a particularly *bad* ratio. As mentioned above, it's less than 1.09 empl./MW, so it's in the same general ballpark as the solar plant.
You seem to have thought this out a lot though your point 4 I'd challenge.
Professors can be wrong sometimes or simply misleading.
16% of the worlds energy already comes from nuclear.
There is apparently a 230-year estimate supply extractable at today's consumption rate with current technologyat current market prices at current rates of use.

36.8 years if tomorrow every single plant was replaced with nuclear if you don't use breeder reactors.
With breeder reactors you could multiply that by something like 50-100
Long enough that it's not a significant worry.
Current market prices is also important: if you increase the price, say double it, then that dramatically increases while not significantly increasing the price of running a nuclear plant as the fuel is very cheap compared to building the reactor.
Now there's claims that it is possible to extract uranium from seawater for about 5 or 6 times the current market price which effectively sets an upper limit on the price of uranium and would supply it forever but I'll wait till I see any kind of large scale operation.
point 2 is valid though it's also true of most industry, hazardous waste can be a serious long term issue even if it's not radioactive, it just doesn't get the same media attention.
point 3 is the most significant one for much of the human race and extremely valid.
