Sorry. But perhaps you could 'holster' phrases like, 'My bet is...', 'my
belief is...', 'clearly this is...', 'my sense is....' and 'I believe...'
These are just opinions and you supply no facts or references to support
them. Your latest post is riddled with such phrases trying to cast
aspersions on the nuclear industry's financial position.

You keep asking for costs per watt. But the financing of *any* electric
power plant is not based on costs per watt, it is based on cost per
watt-hour. Plants don't sell 'watts', they sell energy. If you focus on
only the cost per watt, you do not take into consideration the capacity
factor or plant life. Both are key parameters in any financial decision.
With a nuclear plant's long life and high capacity factor compared to some
other forms of energy, it easily compensates for its higher capital costs.
One of the drawbacks with some forms of renewable is even with a low 'cost
per watt', with low capacity factors it isn't economical to operate them.
If a plant costs just $1.00 'per watt' to build and has zero fuel and O&M
costs, but only operates at 25% capacity factor over a 20 year life, then
the cost per kWh generated is already $0.05 /kWh (assuming an 8% interest
rate on the capital). Some other technology, such as a nuc can cost $2.25
per watt (with 8% interest on the capital) and have fuel & O&M costs of
$0.20 'per watt' (my earlier numbers of $173M/yr for an 850MWe plant). But
by operating at 95% capacity factor, over a 40 year life, then the cost per
kWh generated is $0.047/kWh. Less than the cheaper 'per watt' with no fuel
cost alternative.
Your whole 'cost per watt' argument is flawed. We're talking about
producing *energy*, not power. (the newsgroup is sci.energy)

Again with the 'per watt' argument. Look at it this way, a nuc is doing
well if it can get $40/MWhr on the open market. The companies operating
nucs are private, for-profit companies. They have to pay all the fees for
waste disposal, purchase fuel, pay O&M, pay off the bonds and banks, and pay
into decommissioning funds. They do this all and still pay a competitive
return to their investors. And this is in direct competition with coal.
And don't accuse them of accounting ala Enron, or govt assistance unless you
can provide some proof of such a claim. Even some of your own references
point out that renewable resources are getting govt assistance in the form
of state mandates for non-hydro renewables. But none of the reports mention
any federal assistance for nuclear.

Not germane?? I explained why I believe construction costs will be lower
than the most expensive plants built in the 80's. I supply information
about the 'recurring costs' of operating such a plant. I point out that the
supply side of the nuclear fuel cycle is fully funded by the price of the
fuel. I point out that the end-of-life costs are also being fully funded
from the plant's operating revenue.
I point out that *all* these costs are funded by private industry on a 'per
watt-hour' basis and you continue to drag up 'cost per watt' as if *that*
were the proper way to finance an *energy* source.
The 'cost per watt' is not germane. The cost per watt-hour is what matters.

Do you have some information/reference to support such a *belief*?? You
would have to extend this belief to include other countries supporting their
commercial nuclear power programs as well. Do you believe all countries
with nuclear power plants have governments that are preferentially funding
nuclear over other forms of electric generation? Your 'sense' have betrayed
you in this.

The govt's role in the nuclear industry is regulatory. They make the rules
about controlling special nuclear material and the requirements to ensure
the health and safety of the public. But they do not provide any money to
fulfill those requirements. At least not since the earliest nuclear plants
in the early 60's were built. The NRC's slice of the federal budget is used
for inspection and review of plant design/operation. Nuclear doesn't even
get the tax breaks of 'big oil' for depleted resources.

The price 'per watt' and the 'cost of energy' are *not* a direct conversion.
The lifetime and capacity factor go into it as well. Do the math for even
$5.00 per watt on a plant that operates for 60 years (a few nuclear plant
licenses *have* been extended to this length). Then the total O&M, fuel and
capital costs rises to just $0.073 / kWh (adding less than 3 cents/kWh over
the $2.25 plant's cost of $0.047/kWh)
One of the reasons that coal is such a cheap sources of electricity (besides
the obviously low fuel costs) is that many coal plants are over 50 years
old. One pair of units not far from me was placed in service in 1923. Talk
about your time-value of money, that plant definitely was worth its price.
But nucs cannot operate beyond their license (although some have had
extensions).

If it goes anything like the decommissioning funds of those plants already
shutdown, we will most likely find it *over* funded. The excesses in
decommissioning funds would suggest that the govt mandated fees are
conservatively high (which is a good thing). Why do you believe they will
be insufficient?

In the electricity sector, they compete directly today. In fact the energy
produced by nuclear has *risen* despite no plant construction being started
since TMI. With all the fees and costs they currently pay, they still
provide a healthy return to investors. Nuclear is the second largest sector
of electric generation in the US behind coal at about 20% of all electric
production. 43% of Illinois' electricity comes from nuclear. Not widely
used??

'rate at which it produces power'??? Phrases like that lead one to believe
it is you that are ignorant of the core issues. Surely you mean 'rate at
which it produces energy'. But then you would see the 'costs per watt'
argument for what it is. A red herring.
Well, we probably will never agree on this. I maintain that the 'per watt'
cost is not the proper measure of a plant's economic viability. The cost
'per watt-hour' is (bankers and investors that fund all new plants seem to
agree). I've provided you with some numbers about the cost per kWh of a
typical nuc. All you've done is state that you 'believe' the cost 'per
watt' is greater than $5. Belief is a wonderful thing.

Now you mix up two different costs. Keep them straight. Decommissioning of
plants *has* already taken place. And the funds set aside for it have been
adequate.
If you go back and read my earlier statements, you will see it is the *fuel
waste disposal* that has not taken place and so its funding level is not
proven. Two different items. I'm somewhat cynical about the waste disposal
myself since it is govt run and far behind schedule. But so far your fears
(or mine) have *not* been proven true.

A ridiculous exercise, but fine. Assume Seabrook costs $5B and it's
capacity is 1167MWe. Further assume the lifetime capacity factor is 90%.
($5.0e9 / 1.167e9) / .90 => $4.76 'per watt'. Nine Mile Point II cost
something on the order of $6.2B and has a rated output of 1205 MWe ($6.2e9
/ 1.205e9) / .90 => $5.72 'per watt'. Well, you got me there. One of the
poorest managed, most expensive plants *ever* built came in at over $5 per
watt. Not like any other industry hasn't had such a poor example to chose
from.
Even at 8% interest, Seabrook is only $0.05/kWhr. Refinance the debt at 4%
and it drops to $0.03/kWhr.

You simply refuse to believe that the price of fuel, sold by a private
manufacturer without govt assistance doesn't include all the costs of that
manufacturer's business. Do you believe fuel manufacturers don't pay the
costs associated with their capital investments from their sales revenue?
Or do you believe they receive govt assistance to manufacture fuel for use
both domestically and abroad? GNF supplies fuel for many plants in other
countries as well as here in the US. Is the govt assisting in those foreign
sales somehow? Evidence to support any such belief??
The only cost in the nuc plant life cycle that hasn't been proven in today's
market is the disposal of spent fuel. But estimates of those costs are
currently being paid. All other costs in the life cycle of the plant and
production of fuel have already been proven in today's market.

True it adds to the cost of the energy produced. As I've already shown,
with a construction cost of $2.25 per watt, it adds about $0.19/watt/yr (at
8%). And that works out to about $0.02/kWhr.
But you keep flip-flopping between the 'cost of energy' and the cost per
watt. Stick with the cost per energy.

No. Haven't you been reading anything I've said about the costs of new
construction? Seabrook fell into a very unlucky time frame. After
construction was started, many design requirements were changed due to the
TMI accident. Much of the construction costs had to be paid twice. And
although they had a *construction* permit, they did not have an *operating*
permit. So they spent considerable time (years) in public meetings fighting
with the liberal government in MA (less than 10 miles away) to get an
emergency plan approved so they could begin *operating*. The delays in
getting an operating license caused much of the large cost overruns. And
what were the interest rates like in the '80's and early '90's???
Since Seabrook, the licensing process has changed. It is much more
streamlined. Construction would not even begin today unless the plant had
an *operating* license. There is no particular reason to believe large
amounts of a new plant will have to be torn out and rebuilt after building
it the first time. The NRC has 'pre-approved' several plant designs to make
the engineering and licensing costs much lower/faster.

Gee, if it was 'to promote investment in nuclear power', then why do you
suppose it recommended *against* such construction? If it *were* biased,
don't you think it would have recommended *for* building?

No financial study, including the one I mentioned, looks at 'just the
construction cost'. The study looked at the entire life of the plant from
the first spade-full of dirt to the return to 'green field' conditions. It
included the cost to purchase fuel from private manufacturers, the payments
to fund the federal waste disposal site, decommissing funds and all the
other operating costs. It concluded that the current price to build is too
high to compete with fossil. But it concluded that if the construction cost
aspect could be lowered by ~$0.75 per watt, then it would be competitive.
The term 'stranded' refers to costs that regulated utilities are not able to
recoup when forced by legislation to sell off their generation facilities as
part of deregulation. It applies to any facility (coal/nuc/hydro/whatever)
that is forced to be sold for less than 'book value'. Since some state
legislatures passed laws requiring the sale regardless of price, utilities
have petitioned their public utility commissions for relief from such
losses. Not all the costs have been allowed and many have been 'eaten' by
the utility and its shareholders.

Most maintenance costs are already funded in the ~2 cents per kWh. The 'M'

Interesting. Although NG generation is expected to surpass nuclear, it also
expects that nuclear generation will increase (due to power up-rates and
improvements in capacity factor). Increasing nuclear generation would seem
counter to '
Figure 72 shows a chart of predicted new plant costs. It does not explain
if this is just construction or if it includes other costs. Looking at the
accompanying data, they predict nuclear capital costs of 46.15 mills per kWh
in 2010. At $0.04615 / kWh, and if the plant runs at 90% capacity factor
that is $0.35/watt/yr. For 40 years at 8%, that would mean a present value
capital cost of $4.34 'per watt'. The capital costs listed for wind are
almost as high when calculated properly on a kWh basis (35.93 mills per kWh
in 2010 and 44.34 mills per kWh in 2025). (they don't mention what capacity
factor or lifetime they assume for wind) Of course wind is much cheaper
'per watt', but it has a much lower expected life-time energy production.
This is the flaw in your 'cost per watt' fixation. Again, plants don't sell
'watts' they sell 'watt-hours'.
But it doesn't say anything about capital costs of $0.20 per watt either.
Where *did* you find such a figure? If you're going to accuse the DOE
and/or the nuclear industry of hiding costs or ridiculous claims, it would
be nice to be able to read the statements for myself.
