The greatest threat posed by a nuclear (fission) power plant is:?

March 11th, 2012

Question by Red O: The greatest threat posed by a nuclear (fission) power plant is:?
The greatest threat posed by a nuclear (fission) power plant is:
a.Release of radioactive isotopes when the molten core reaches the water table.
b.Fish kills resulting from use of local rivers for cooling.
c.Having the core melt, ultimately reaching China.
d.Thermonuclear detonation.

Best answer:

Answer by Scott K
In my opinion the wording isn’t very good but I would chose A.
B is not a large concern.. all it does is vent hot water which can disrupt ecosystems but is hardly as dangerous as a meltdown.
C talks about a core meltdown (which is the most dangerous thing), like what happened at Chernobyl. But it would certainly not keep going and reach China. The biggest danger is the airborn radioactivity from a meltdown. The first answer does the best to address this danger.
D does not occur. There is no chance of a detonation from a power plant. It does not use weapons grade material.

Why do spacecrafts not use nuclear fission for power?

March 2nd, 2012

Question by : Why do spacecrafts not use nuclear fission for power?
Couldn’t nuclear energy greatly increase the speed and power of a space craft?
@anonymous – what does mass have to do with anything if your are in a no gravity environment? Mass in terms of weight is only an issue in environments with gravity. A space craft using nuclear energy would need to be kept in space at all times obviously.

Nuclear fallout at all levels, old outdated plant leaks or Fukushima IS CANCER kevin d. blanch

February 24th, 2012

The existing plants in the United States are grossly inadequate, how can we keep building more when we cannot take care of the ones we have

ploaded by MsMilkytheclown on Sep 20, 2011 Fairewinds Introduces a Japanese Language Edition and Identifies Safety Problems in all Reactors Designed Like Fukushima vimeo.com Gundersen expresses concerns that the nuclear industry and the Nuclear Regulatory Commission are not addressing major safety issues that have become evident since Fukushima. These issues include serious design flaws in the BWR Mark 1 containment, fundamental flaws in the Boiling Water Reactor vessel design, and problems with detonation shockwaves. The NRC and the nuclear industry are using a flawed cost benefit computer code that underestimates the value of human life and minimize property damages after an accident, which has the effect of justifying continued operation of reactors without safety modifications. Also, Fairewinds announces the launch of the Japanese language version of its site, Fairewinds.jp. sidenote: I edited out a couple of minutes to stay under the 15 minute upload mark.

Q&A: Can you you control a nuclear fission reaction to power a spacecraft?

February 15th, 2012

Question by : Can you you control a nuclear fission reaction to power a spacecraft?
Is it possible to contain a nuclear fission reaction (or better yet, fusion reaction) and direct the thrust from the reaction out the back of a spaceship in order to power it at 0.5 G’s?

Best answer:

Answer by Starrysky
http://settlement.arc.nasa.gov/teacher/lessons/contributed/thomas/Adv.prop/advprop.html for NERVA atomic rocket engine, others. Pretty scary if it pollutes or goes wild.
There are plans to use nuclear engines for low thrust for a very long time on space probes. An early ion rocket has been employed on a comet probe. But to achieve 0.5G will take much more mass and shielding than has been attempted or even planned so far.

How would the nuclear power plant explosion in Japan be different from the one in Chernobyl?

February 10th, 2012

Question by Leopard Gecko 2.0: How would the nuclear power plant explosion in Japan be different from the one in Chernobyl?
Also, If the nuclear power plant in Japan is already experiencing explosions why has it not been blown to pieces yet?

Best answer:

Answer by Alex
Because the explosions, while contaminated with radiation, were not core explosions like what happened in Chernobyl.

That one blew huge chunks of the core fuel all over the place.

Japan is facing not an explosion hazard so much as a meltdown risk.

What is a viable alternative to nuclear power generation?

February 1st, 2012

Question by Swtf: What is a viable alternative to nuclear power generation?
Following Japan’s nuclear problems environmental groups are baying even more for ‘nuclear power generation’ banishment.
Do they have an alternative power source?
Wood?
Coal?
There are problems with these sources as well.

Best answer:

Answer by dawa
there are many alternatives, but the technology has to improve a lot. for example. thermal and solar are one of the best option available for generating clean energy. Hydroelectric power is also one of the cleanest form of energy production, except if don’t consider its effect to the surrounding land and habitats. Another interesting form of energy production can be in a form of Pizeo electric power.. although this technology has to go a long way, but it can be a good option, especially in a populated area and if we prefer local energy production.

How does the balance of power shift if Iran becomes a nuclear power?

January 31st, 2012

Question by Mad Max: How does the balance of power shift if Iran becomes a nuclear power?
It seems to me that it is inevitable that Iran becomes a nuclear power. Bush was unable to stop North Korea, and didn’t stop Iran. Obama is unlikely to go to war in order to stop Iran, and even Israel is unlikely to at this point because the reactors now have nuclear fuel in them.

Once Iran becomes a nuclear power, what other countries will become nuclear powers, and how will this affect the long term strategic interests of the US? How will it change the balance of power in the world?

Best answer:

Answer by Oldwhiteguy2earth
The concern is not so much the balance of power as much as it is the sworn goal of Iran to wipe Israel off the face of the map. Since Muslims will be rewarded in Heaven, someone in the Iranian hierarchy could possibly light up the Middle East without regard for the consequences.

Why does nuclear fission AND fusion release energy?

January 27th, 2012

Question by : Why does nuclear fission AND fusion release energy?
The Sun undergoes nuclear fusion, combining hydrogen to form helium and so on, but it also releases light energy in the process. Nuclear fission (splitting the atom), however, also releases light and heat energy. How does this work? I would think that nuclear fusion would take IN energy in order to fuse together the nucleuses of atoms. And then when an atom splits, energy would be released because energy is stored to keep the bond between nuclear particles. So why would both processes release energy?

Best answer:

Answer by Roger S
In both cases the mass of the objects after the reaction is less than before the reaction. The lost mass has been converted into energy in the form of electromagnetic waves.
