Not really. Only a handful. Most are >50miles inland, and there are only two in the US within a dangerous earthquake zone (the two reactors outside Los Angeles).

In addition, all of our "coastal" reactors (none are actually on the coast) are on the east or gulf coasts, which have very low tsunami risk factors.


Basically the LA reactors are in an unsafe area and should be scrapped, and there are a couple downriver of major dams that should also be reevaluated, safety-wise, but the vast majority of US reactors are very well situated.

glad to see nuclear energy going out. anyone ever think the whole global warming thing is a lil cheesy? i mean al gore made millions with this " green energy thing " also plants use carbon.. lol idk not trying to start something just saying i think replacing Carbon with nuclear energy was/is a bad idea..

Maybe we can all power our appliances with treadmills. I'm powering my computer with a stationary bike right now, about to run Prime95 so I better pick up the pace

I wish more articles and news headlines would specify which nuclear energy they are talking about when it comes to energy. The general public simply hears the word "nuclear" and they think radiation and death. They need to know the difference between fusion and fission.

It is a LOT safer when you look at the potential for damage a meltdown can cause. People like to talk about all the redundancies and how safe a modern reactor is but you can't account for an act of God.

If a big earthquake hits, a tsunami, tornado, etc., and you lose containment you could end up making large swaths of land unlivable. If you they can design a reactor that got rid of the component somehow then fine, but until they can I think the risk, even if small, is too great.

Anyway, solar continues to be develop, current efficiencies are very low, once they are able to get higher efficiencies solar will have a MUCH great potential, especially compared with better battery technologies that are being developed. That coupled with some wind farming, hydro-electric, and some other types of environmentally friendly and renewable energy sources that are being worked on and I think we can avoid nuclear and fossil fuels.

They can. Look up pebble bed reactors.

As usual, the luddites are trying to block funding.

Some reading:

Quote:
When the nuclear fuel increases in temperature, the rapid motion of the atoms in the fuel causes an effect known as Doppler broadening. The fuel then sees a wider range of relative neutron speeds. U238, which forms the bulk of the uranium in the reactor, is much more likely to absorb fast or epithermal neutrons at higher temperatures. [2] This reduces the number of neutrons available to cause fission, and reduces the power of the reactor. Doppler broadening therefore creates a negative feedback because as fuel temperature increases, reactor power decreases. All reactors have reactivity feedback mechanisms, but the pebble bed reactor is designed so that this effect is very strong and does not depend on any kind of machinery or moving parts. Because of this, its passive cooling, and because the pebble bed reactor is designed for higher temperatures, the pebble bed reactor can passively reduce to a safe power level in an accident scenario. This is the main passive safety feature of the pebble bed reactor, and it makes the pebble bed design (as well as other very high temperature reactors) unique from conventional light water reactors which require active safety controls.

The reactor is cooled by an inert, fireproof gas, so it cannot have a steam explosion as a light-water reactor can. The coolant has no phase transitions—it starts as a gas and remains a gas. Similarly, the moderator is solid carbon; it does not act as a coolant, move, or have phase transitions (i.e., between liquid and gas) as the light water in conventional reactors does.

A pebble-bed reactor thus can have all of its supporting machinery fail, and the reactor will not crack, melt, explode or spew hazardous wastes. It simply goes up to a designed "idle" temperature, and stays there. In that state, the reactor vessel radiates heat, but the vessel and fuel spheres remain intact and undamaged. The machinery can be repaired or the fuel can be removed. These safety features were tested (and filmed) with the German AVR reactor.[6] All the control rods were removed, and the coolant flow was halted. Afterward, the fuel balls were sampled and examined for damage and there was none.

Fail but I have faith in the Germans.

Hell if Germans can build a stealth fighter in 1944. They can build anything first.

This is something that was supposed to have happened a long time ago (if you follow German politics).
