Omissions and Statistics.
You think I didn't read the paper? The study admitted to a very low sample size with a variety of issues that interfered with the final costs of each plant.
Also from the same paper:
'If we examined the cost of construction for a coal or wind plant, we would expect to find similar cost increases'
But the study did not examine the cost of construction of either. You're lying about making a valid comparison. The grid integration costs for wind would be huge for the simple reason that supplying the dispatchable power (often in the form of pumped hydro or natural gas) incurs much higher capital costs than nuclear.

Discounting and waste
Fretting about several thousand tons of spent fuel is innumeracy at its finest. Anyone who understands the very basics of discounting can see why.
Stick the dry storage casks in a parking lot. Check on them in another 100 years an reseal if necissary. Chances are in several hundred years at the very latest we'll strip out the actinides for fuel anyways, in addition to the xenon and platinum group fission products.
Geologic repositories are misdirection solutions to a nonproblem. They arent necissary and never were.On So says a new report posted 2 years, 5 months ago 44 Responses
Makes the flowers grow
In comparing costs of wind to costs of nuclear, you're being incredibly disingenuous. You're taking the worst experiences reactor cost overruns in a heavily regulated environment prone to disruption and capital mismanagement with low expected reactor lifetimes and comparing them to the best anticipated scenarios for wind. You're anticipating a ridiculously high interest rate and very long build times, and yet with wind you're anticipating everything working smoothly, that supply chain disruptions will fix themselves where for some reason they wont with nuclear power.
And still not factoring in additional infrastructure cost for dispatchable storage to counter winds behavior as a negative load rather than a base supply.
Experience with massive nuclear infrastructure projects in France shows nothing of the 8-11 cents per kw/hour that you're inventing, and yet wind shows no sign of being less expensive baseload than nuclear anywhere.
In short... you're lying; Cooking the books for a desired outcome.On So says a new report posted 2 years, 5 months ago 44 Responses
No leukemia/spent fuel link
Every onsite lot for dry casks is a repository, and good enough for centuries to come. Geologic repositories are a waste of time and money.
And where in the New Scientist article (not exactly lacking in sensationalism) are there any links for anything related to leukemia caused by spent fuel or even mine tailings. The most there is mention of is nominally highe rate of lung cancer by uranium miners... not necissarily caused by what we normally define as nuclear waste unless you consider granite a nuclear waste also with it feeding radon into unventilated basements.On So says a new report posted 2 years, 5 months ago 44 Responses
Leukemia and waste?
Could you post a cite to something that isn't sensationalism? I've seen no epidemilogical studies linking spent fuel or nuclear waste to luekemia.
The only thing that has direct correlation in nuclear power production is when Chernobyl blew in an area with iodine deficient children with no stay indoors orders; A thyroid cancer spike. But this isn't indicated in any studies from spent fuel or more generic nuclear waste.

With the assumptions that drive nuclear power end costs to some 10 cents per kw/hr, you end up easily driving wind to 20. They have the same top heavy capital cost requirement except that you get more KW more reliably from nuclear power and have to spend less on dispatchable power subtitutes (peaking natural gas or pumped hydro systems) along with plant operating lifetimes at least 2-3 times as long.

People who decry discounting never seem to see their prophosies of doom come to pass.
On a side note for the mark versus the dollar... Such a currency collapse is impossible. The Weimar republic owed their debts not in marks but in foreign denominated currency.

Here we could also do it this way. Build a lot for storing nuclear waste. Put some cash in an account that pays interest on paying the upkeep for it.

Many people choose to just disbelieve it. It doesnt make it go away. Economic growth is here to stay, and discounting allways makes sense because its simply the concept that its better to plan for today first, then tomarrow, and then the day after.
If you try to plan for jan 17th 2571 before planning for tomarrow, theres no hope for you.
As for the rest of these doomsday scenarios of immenent population decline and economic collapse; Well some people beleive the darndest things.On Join me for some navel gazing! posted 2 years, 8 months ago 69 Responses
Indeed a poor analogy.
I could go on, but hopefully you get the point. There's no analogy here.
True enough. CO kills millions every year while spent fuel hasn't killed anyone.On Join me for some navel gazing! posted 2 years, 8 months ago 69 ResponsesThe nuclear waste issue
So, you and others have now provided additonal information that the fuel enrichment cycle only consumes 1 to 4% of the net output.
This half truth is incredibly misleading, especially when all the diffusion plants are due to be decomissioned within the next ten years.As for the nuclear waste issue: This has been solved years ago. Its as simple as sealing it in a concrete cask in an above ground lot. Theres no shortage of space for it and discounting does wonders for the storage cost. In 100 to 200 years we revisit the storage casks, reseal or recycle the material depending on the market conditions of the future.On Join me for some navel gazing! posted 2 years, 8 months ago 69 Responses
Enrichment is still a minor cost.
If you do the math with those numbers and factor in the plant in the report is over 3,000 MW, you come up with a figure of roughly .9 TWh, compared to the annual output they list of 23 TWh. This is almost a 4% net loss in the output of the plant just for the enrichment process, not counting construction of the facility or any of the other life cycle costs.
And its nearly inconsequential. You could make up for that loss just by raising the temperature a hundred degrees or switching to centrifuge enrichment. All modern enrichment facilities under construction are centrifuge plants for this very reason.Even still with diffusion enrichment it only represents half the cost of the fuel.
Modern gas centrifuge plants require only about 50 kWh per SWU, and provide 65% of the enriched uranium globally today anyways.
The notion that nuclear power is in any way an energy sink is profoundly flawed.On Join me for some navel gazing! posted 2 years, 8 months ago 69 Responses
