This is just another in a long list of fact free conclusions you've jumped to.
Just look at a basic guide for investors to get at least a clue.
Moody's:
Moody’s is considering taking a more negative view for those issuers seeking to build new nuclear power plants. Rationale is premised on a material increase in business and operating risk.
Citigroup: We see little if any prospect that new nuclear stations will be built in the UK by the private sector unless developers can lay off substantial elements of the three major risks. Financing guarantees, minimum power prices, and / or government-backed power off-take agreements may all be needed if stations are to be built.
Risk plays an important role in the nuclear analysis because of the history, long lead-times,
and economic and technological uncertainties involved in reactor construction and operation. The
decision to commit to a reactor that requires a long lead-time and produces a large quantity of power
creates sunk costs and results in rigidities that are vulnerable to changing economic, regulatory, or
financial conditions. Over the long construction and operation period, things can change, rendering
the initial decision uneconomic.
Regulators should not assume that ratepayers should bear the real risks of building nuclear
reactors. A decision to authorize a reactor that has the risks identified above can impose severe costs
on ratepayers, the utility, and the local economy. In addition to imposing excessive costs on
consumers, a reactor may become uneconomic during its long construction cycle due to the
development of alternative technologies, thus weakening the economy of the service area and the
financial status of the utility.45
In the regulatory context, there is a tendency to try to shift the risk to ratepayers before and
after the construction decision is made. Before the decision is made, utilities try to shift risks to
ratepayers by seeking recovery of costs before the plant is in service. After a decision is made, if
something goes wrong, the utilities will argue that they made the best decision they could at the time
and therefore should not be held accountable when things change. In a competitive marketplace,
however, they would bear the risk of their decisions, but also reap the rewards if the costs they
incurred were lower than other alternatives available.
Beyond the risk of cost overruns, marketplace and technological risk should be taken into
account in the resource planning process. Extensive assessment of the cost and availability of
alternatives should be made to ascertain whether the proposed plant is likely to be the least costly
alternative. At a minimum, the public utility commission should consider the likely technological
developments during the construction and early operation phase of the nuclear reactor, identifying
alternative technologies that could meet the need for electricity in that time frame.
A variety of mechanisms are available for incorporating risk into the decision-making
process and allocating the risk to various stakeholders. For example, commissions can put a cap on
costs, forcing utilities to bear the burden of cost overruns. The important point is to recognize the
risk and make its allocation explicit and transparent.
Figure VI-1 presents three characteristics of generation alternatives from the Lazard study
that, as we have noted, underestimates nuclear costs significantly. Nevertheless, it shows that nuclear
reactors are not the preferred option by a long shot. It shows the consumer cost, capital cost, and
the construction period. These are three key determinants of risk, as discussed above. Capital costs
are sunk costs, which render the option inflexible; long lead-times not only allow consumer costs to
escalate, but also give alternatives more time to develop, thus improving their competitiveness.
Finally, high consumer costs may reduce demand. The smaller the circle and the closer to the origin,
the lower the cost and the less risk.
The Lazard study used a construction period of 69 months for nuclear, but others have used
much longer time periods. Even with the underestimation of capital costs and the relatively short
construction period, nuclear has a unique set of characteristics that are unattractive from the risk
point of view – combining high costs, large capital outlays, and a long construction period. The coal
based alternatives present about the same risk profile as nuclear reactors. There are half a dozen
options that are clearly superior to nuclear reactors on all three risk dimensions, and the lowest risk
alternative. Efficiency is not shown because Lazard estimated only the cost, which, as we have seen,
is quite low. Efficiency would certainly have a short lead time and a low capital cost. If it were
included it would be the most attractive on all three risk dimensions. p.54
