Construction delays speak more of bad project management than bad conceptualisation.
There is a track record of performance of nuclear power facilities. Ontario Hydro operated power plants seem to have performed very well for almost 50 years. There is the three mile island failure and the chernobul failure. However, these can both be traced to an instance of human carelessness or willful lack of adherence to specifications.
There is no track record of performance of windmills. Thngs could go wrong with them. For example, how long do the mechanical components of each windmill last? That is, with the enormous and complex rotation stresses and associated residual magentic fields created in the metal components, how long will they continue to operate before cracks appear and catostrophic failure occurs. What would happen if an enormous wind propeller snapped off and flew through the air and how would the remaining components react to the imbalance should that occur? Would a propeller designed to operate with three blades become dangerously unstable if one of the blades became disoriented or dislodged?
To understand where I am coming from, here are two scientific experiments you can conduct with simple and available items:
1. Take the front wheel off your bicycle spin it fast and hold it by the axle (the part that bolts to the front forks of your bicycle); do you feel a force and strain in your arms? Stand in a canoe and do the same thing; did you get wet?
2. Another experiment would be to stand next to your house and spin around in circles holding an extended hockey stick until you get dizzy and feel the grip of your hand slipping. Then let go of the stick and watch what it does to your windows. Compare the size and weight of the icehockey stick to that of a wind propeller blade.
I would prefer having a properly built and operated nuclear power plant next door than a windmill farm. While the chance of radiation leak is zilch, the unknown instance of when a propeller blade may dislodge and fly through my house, bedroom, bed and me or if a destabilised tower might come crashing down would create a great deal of stress for me that would be about as dangerous to my health and wellbeing as a radiation leak. The stress is 100% likely and the radiation leak is 0.000000001% likely.

Here's some info to add to the discussion of nuclear power costs.
According to a recent article by Julio Godoy, construction costs for nuclear plants are very risky to finance, and can rise substantially over the long construction period needed. Construction delays present additional risk, as has happened with the Finland plant that Jon mentioned, with a projected delay of three years and cost to build increase of 2.3 billion Euros so far. Nuclear power plants take at least 60 months to build; wind plants 18 months. The costs of constructing a new nuclear power plant range between 2,500 to 3,500 euros (3,420 US dollars) per kilowatt hour; no comparison figure given for wind. Full life cycle costs were not presented.
ENERGY: Nuclear Does Not Make Economic Sense Say Studies
By Julio Godoy
BERLIN, Feb 12, 2010 (IPS) - The enormous technical and financial risks involved in the construction and operation of new nuclear power plants make them prohibitive for private investors, rebutting the thesis of a renaissance in nuclear energy, say several independent European studies.
