It's not that it wears out "sooner", but it wears out before you can recoup the savings, because the technology is still much too expensive to realize any cost savings.............. If I had to buy a new car today I'd get a Jetta Turbo Diesel. 40 MPG city. I can live with that, and buy more guns with the savings. Bill T.
That's the rub...cost. Governments can be good at big things that business can't support...I mean, if you had a great idea and you would have to spend your own money (never mind where you get it from) for 20 years or so would you be willing to work on it without a paycheck? This is where I think there are good social progams...research programs.
The current technology is too expensive...but only because it is too inefficient. If you could spend the same amount, get more for your dollar, and have it last a couple of decades then OK, which is where research into materials, material properties and base research supported by a government that does not have to turn a profit on a project or starve comes in.
Also...on the diesel...since the government raised the tax on diesel I don't know if we'll see a plethora of diesel vehicles. I agree we should, I have an F250 diesel, but with the price of diesel (lower cost to refine, less waste in refining) being artifcially higher because of the government it may be a stretch. I think diesel is the right answer to offer the public to vote on with their pocketbooks.
In spite of our reactor "Knowledge" over the Soviet Russians, (Or whatever you want to call them now), we still managed to damn near melt down Three Mile Island. ........
As was well known in nuke circles and since has come out in the literature, there were by regulation supposed to be three coolant systems 100% operational at the time of Three Mile Island. The issue was there was one installed in service, one installed with being fully in service and third on order not hooked up. The operation at the time was illegal since the three systems were not operational.
Next, all the braintrust diagnosed the problem as problem A and applied solution B...thankfully the problem was B not A.
They did not want to scram the reactor initially to prevent cooling the beryllium alloy reactor shell too quickly which produces stress cracks and reduces the useful life. So...they switched over to the 2nd coolant system only to find out it was not fully operational...thence came the meltdown.
The hydrogen bubble that was the big deal...really was since at temperature hydrogen is highly reactive with the zirconium tubes the uranium is encased in so...actions that increased the bubble size increased the disaster by consuming the zirconium and allowing the uranium to pool up and increase the reaction. This one nearly got away from us.
Yes...indeed Bill, be concerned for the operators of the plants.
