This issue is also related to water shortage and drought-read the article on this relationship.

Already, wind energy can produce electricity for less than five cents per kWh, and concentrated solar power can produce energy for 11-12 cents per kWh—even at night—and these costs are decreasing. Alternatives do not produce nuclear waste, and they do not face the same extensive safety, regulatory, and construction costs and delays that nuclear does.

Excellent! You seldom hear these important issues brought up. We don't have answers to nuclear energy's problems yet.

We have one to solve meltdown and needed water. Check out Pebble Bed reactors. Uses graphite encased uranium tablets (making it harder to retrieve spent fuel for weapons and lowers the radiation damage of spent fuel). It uses the fuel to heat an inert gas (free of contamination in the event of a leak) in turn expands creating pressure. The pressurized gas is used to turn a turbine and then is cooled for reuse.

No water is needed to cool the pressure vessel. The pressure vessel with the inert gas is incapable of heating to super critical temperatures.

Fossil fuel puts money in the hands of people who do not seek to better humanity. Don't cry for their loss.

P.S.: Nuclear energy is the most powerful of the alternates. Solar, wind, tidal, and bio-fuel can barely hold a candle to the sheer amount of electricity that is generated by one Nuke plant.

They may be more expensive for one unit. However the same amount of cash invested into x units of the other "possibilities" does not yield the same power generation.

RD thanks for your comments-more understanding of the options and risks by the public is critical if this is the way we're going. Did you see the clip about the recent river contamination in France? Are you able to state confidently that there will be no catastophic accidents ever, and no proliferation towards expanded nuclear weaponry by more nations? I am willing to change my mind but does this wonderful benefit you forsee really truly outweigh the potentioal risk? I want to see that one answered clearly and I don't see how it can be. Until then, I am against this coming worldwide nuclear renaissace, no matter what THAT costs, including using a bike and candles.

China has one, south africa is building two (Peb. Reactors). MIT and Berkley Profs attended an actual coolant shut down at the one in China.

If the reactor was a standard type (rods submersed in water in a pressure vessel) and was unable to shut down when there was a lack of coolant. The entire thing would meltdown. (The fuel becoming so hot that it melts the pressure vessel and vents contamination).

Of course we will always have storage issues (something I am not afraid to admit) however the risk, when approached with respect to the damaging nature of the materials in question, and the safety of all people involved, can be mitigated.

Preventing development of other nuclear powers is hop...

Just thought about number 8 for a second. A mature technology, It will not get any cheaper.

If it is a mature technology, why are there dozens of "types" of reactors that have been developed. Fast Breeders, Standard Pressure Vessel in four generations of improvement, liquid sodium, and of course the before mentioned Pebble Bed type. There are dozens more I cannot recall from memory alone.

Of the Standard type, all US reactors are first gen. all other gens have been built by colleges, yes... educational institutions are the driving force behind nuclear technology.

As for number 10, the subsidies, is simply a red herring. A nuclear reactor (other than naval) has not been constructed in near...

thanks for your points. I respond to logic and reason and you are speaking from that angle. If I put a personal wind turbine and solar panels on my home, yes I could farm here just fine. Please help me understand why solar, wind, and other alternative energies aren't better overall given the risk you admit.

History has shown repeatedly that we innovate and practically give our technology away for producers in other countries to turn around and exploit us. Nuclear is no exception. You are preaching to the choir.

Given budget constraints, aren't subsidies given to nuclear in effect taken away from alternatives?

Thanks.

IRT subsidies, the lions share goes to nuke plants when they are being constructed. They generate enough income for employ and spare parts.

But then again one hasn't been built in decades.

Things like wind and solar are great, but not very feasible in land vs efficiency. I've been a city dweller much of my natural life. Without a steady flow of electricity, living within a city would become nigh impossible in this day and age. People have forgoten how to farm, how to hunt, how to butcher meat (not me, kind of a survivalist in a suit). The cost and size of a "natural" power generation facility to power the city I am dwelling in is staggering, and it remains that way even if you manage to ge...

Nuclear is very safe. Opposition is mostly irrational and fear-based.

Thankfully our State has just Today approved 2 new nuclear site constructions. They should be functional app. in 2017. Too bad they didn't start this 10 yrs. ago. :~( However, I believe the safeguards and scientific advances over these years have made nuclear power safer and more functional.

Nothing ventured, nothing gained. It's time to 'venture'.

Sweet pioneering spirit, where have you been?

Festering in a grave of commercialism my friend.

Sorry I didn't finish this conversation, a death in the family has kept me away. I'll do more research, but the bottom line for me is there's got to be a better way, and we ought to find it. The river closing in France is just the beginning of the news we'll hear.

Over seventy percent of the energy generated in France is Nuclear.

I don't believe there is anyone on the planet who can know with certainty that the rewards of nuclear energy outweighs the potential catastrophic risks. I predict a nuclear plant sometime in the future will indeed have such an accident. Hope you aren't anywhere near it.
