Nuclear power is often referred to as a 'clean' power source, when using it was first being planned the scientists of the time thought that they would produce free energy too.
In fact most nuclear power stations have not covered their own costs when compared to more traditional power production.
My main concern with nuclear power is safe disposal of the waste. I'm also concerned about accidental emissions as the result of accidents.
I've just been revising for an exam about radioactive waste and have been reading a document by DEFRA written in 2004 that states that the assumption at the time was that the "remaining operational power stations will be shut down over the period from 2006 to 2035". I know Tony Blair was all for new power stations being built though (I don't know Gordon Brown's feelings about it).
I don't like the idea of more nuclear power stations being built.
So, do you think nuclear power is good?
If not, what are the alternatives?
Also, does anyone know what the plans are in their country for the future of nuclear power?

I don't have any problem with nuclear power. I have a degree in physics and understand the processes and dangers involved in nuclear reactions. Yes, we need to figure out how to deal with the waste efficiently and cleanly, but the amount of power that is produced far surpasses that from coal plants. Coal plants are extremely inefficient and dirty and produce huge amounts of pollution (although there are technologies being devised to help with this).
The reasons nuclear plants are being shut down are not for practical reasons but political. There is a perception that they are not safe and clean so people don't like them. But the reality and the science would suggest otherwise.
Nuclear plants are quite safe.

Thanks for your response. I agree that coal plants cause a lot of pollution and an alternative needs to found for those but I'm not convinced about nuclear power.
Thinking about disposal of the waste I just hope that no-one tries disposal in space until space travel is much safer as the possibility of the relase of tonnes of radioactive waste in the upper atmosphere is quite likely using current technology.

Disposal in space isn't an option and I don't think it is something they are even seriously considering. Disposal of the waste is really the only drawback of nuclear power. That being said, modern disposal is pretty safe and clean. The issue is not really how unsafe disposal is, but if all the regulations are being followed.

yes I'm strongly in favour of the research,development and efficient use of nuclear power, but only if it is handled by sane people. I, myself want to be a nuclear engineer, not only because I'm fascinated by the enormous power it has, but also because I believe that the progress of nuclear energy is one of the only ways to sustain the requirement of ever-growing need for energy in the present times.
In one of my school activities, I had put forward a concept that could prevent explosions in areas where petroleum is extracted, by the use of capacitors, to which energy can be provided by nuclear fission reaction.
If the hydrogen bomb has the strength to destroy entire life on earth, just think that how useful its energy can prove to be if we come out with something that can provide this amount of energy to sustain human needs!oh!!I'm in awe of nuclear power.Lol!

I think nuclear power is safe as long as proper safety protocols are followed.
The problems arise when shortcuts are taken during construction, and operating procedures are not followed.
Although they can be safe and a clean source of energy, when something does go wrong it makes a really big mess.
Waste disposal is a problem that really needs a solution.

I think nuclear power is a good thing but is also danger.
if I can choose, I think use more sun power is better than use more nuclear power.

Modern solar panels are EXTREMELY inefficient. There is no way (at least with current technology) to power cities with solar power.

I saw a program on the Science Channel the other week about the new solar panel technology. They are making new arrays of more efficient collecters. The result kind of looks like a sattelite dish, moves to follow the sun, and has mirrors to concentrate the rays. They can now power 5000 homes with about the same amount of space as a wind farm would occupy. I know that still isn't enough to meet our needs, but they are making good progress with the technology.

Indeed. And it is great that are making progress. Existing solar panels were something like a few percent efficiency, pretty ridiculous. The new ones will be a good step, but still a VERY long way off. Wind farms are giant, even if they could power 5000 homes, it still has a long way to go. Hopefully some day!

erm.. first of all .. i think nuclear power has its own advantages and disadvantages... we can't say that nuclear power is totally useless.. but we can't say that it will do us any good either.. as it produces much radiation which is harmful to our health..well.. i think we shouldn't use nuclear power for wars or to generate electric power as we're still very unclear about the consequences it might bring.. do you agree with me? who knows.. our future generation might get threatened by such dangerous power.. .. i don't know but this is just my opinion..

yes...even I think nuclear power is useful and also very disadvantageous at times..the nclear power of a nation signifies their potential strength as a strong nation....an is a sort os safety mesaure for the nation..but it is highly dangerous for human beings....the nulear power reactors have harmful radiations which greatly affects the haemoglogin content in the blood...and ofcourse the nuclear waste is also a harmful waste to the atmosphere as the nuclear waste is a form of spent fuel ..which is very hramful to the surroundings...

i think nuclear power stations are ok as long as the disposal of radioactive materials are taken care of,. if somehow we could achieve full safe disposal of radioactive materials with 0 % risk, it would be great for the world.
i think nuclear power stations ahould not be built unless there is safe disposal, hydro energy couuld also be considered as a clean and riskfree source of energy

Hydro power is very good. Unfortunately, whenever they make a new power plant on a river, they first build a dam, which devastates and destroys the ecosystem for miles behind the dam. Sometimes, it displaces whole villages and towns of (mostly poor) people.

i think that building a dam is not always necessary, only a source of water is neede like falls. i think you need dam for very high power generation, i was talking about small power generation like 1mw to 5mw , and having more number of units

Nuclear power has actually been present in our world for quite some time. I think that like anything else in this world, everything can be abused and misused, resulting in a catastrophe. I do think that when harnessed properly, used properly and disposed of properly the idea of nuclear power is quite wonderful. It's when we abuse the idea, abuse the correct methods and ignore the truths about it that we get into trouble. But as a strict yes or no answer, yes I do think it is good. It just has it's bad points that must be addressed.

Well I don't mind the nuclear energy taking place instead of the current sources of energy as long as the waste have been disposed off perfectly and it is beneficial to both the environment and the mankind.

nuclear power is some sort of a good thing and same a bad things as we know every picture has two faces ...one bad and one good face .....nuclear power is the same you use it good you have many things electricity like etc ...you use it bad and you have bombs and radiations ....
its not the technology which is bad it is the use which is bad .....i think the use of the technology says it all ...if you use it good it will help if bad ....nothing can be of help !!!! .....

Hello,markyB21,I think if the risks of using nuclear power can ne minimized,the benefits may outweight the disadvantages.As we have limited supply of coal and oil to generate electricity,nuclear power may be one alternative for them and the cost is relatively low.With the rapid expansion of population in the world,we need to find extra source of fuel for generating electricity. We also have to keep an eye on whether those countries are using nuclear power for proper purpose.
Australia is having some discussions about developing nuclear power but the details are yet to be confirmed.

As far as the safety features of the nuclear installations are not rigged up, and all the safety procedures are followed, there is no problem in nuclear power being a prime source of power. there are regulatory authorities to look after if the powerstations are keeping the safety margins good enough, and whether these stations are adhering to the safety standards stipulated or not. This should make nuclear energy safe.

to develop country's economy,need nuclear power to product electric power,many country have lack of energy sources,so they use nuclear power as their energy,but nuclear is a radioactive element,it is bad for animals health,even human being life.and also can be polluted our envrionment.

I think nuclear power is a good thing and we need to promote it if we want to cover the ever growing demand for power infact the indian govt and several private and public enterprises in india have submited proposals to the govt regarding setting up of neuclear power stations. You may be right that they have not covered their costs but every new venture has its gestation period. Yes there are dangers of leakages and questions regarding disposal of neuclear waste are not fully answered but these should not lead to stoppage of nuclear power instead efforts should be made to address these issues. Other means of production of enery like hydro and wind energy should also be encouraged.

No nuclear power station in existence has covered it's costs in energy produced when compared to the cost of producing energy with traditional (coal, gas etc) methods.
The resources used in building them in order for them to be safe are astronomical and then the waste needs to be stored in the least corrosive materials available including copper, gold and platinum - not cheap.

That isn't necessarily the case. Depending on which study you look at, you will get conflicting answers. The way I have seen it, Nuclear is still the most cost effective. This is ESPECIALLY true if they plants are actually allowed to live out their full cycle instead of being shut down early. Of course they are a waste of money if they are allowed to do what they were designed for.

But they do cover their costs and most definitely would in India. Nuclear energy would be of huge benefit there because of the large population density there. Reduction of pollution due to the use of nuclear power would be extremely helpful there.

Hi markyb21,
solar radiation is between 100 - 200 watts/m², depending on where you are on the globe. Average that over 24 hours and that's back to maybe 50 watts/m² continuous. With 25% efficient solar cells and suitable storage devices, you might get an effective continuous 10 watts/m² from solar power. If you managed to plaster a suburban roof with solar cells, on that basis it might produce equivalent to 1 kwatt continuous. Roughly equal to an ordinary mains power point.
Two things to note -
1. 1 kwatt continuous is equal to 24 kwatts for 1 hour per day, or 2.4 kwatts for 10 hours per day. Or 8,760 kwatt hours per year.
2. How many power points does a house need to max out 24 hours a day to get by? A well-designed, conservatively managed home might be able to get by on that amount of electrical power - some for the fridge, some for the TV, some occasional heavy loads, some for lighting.
As for nuke power stations, I'm all in favor of them. They are essentially just glorified steam engines, without the need for coal or wood to run them. And they'll go for an awful long time on just a handful of uranium.
Sure we can manage the world on an ecologically sustainable basis, with more forests and cleaner air, and better use of sunlight. And we absolutely should, without a doubt. I'm quite passionate about those issues.
But here's a principle to consider - nuclear power is the only "clean" source of energy that we have that DOESN'T depend on the Sun.
Yes, let's develop every means we can to harness the Sun's energy.
But let's also not forget that we have absolutely no clue in the world exactly what the Sun is or how it actually works, or what it's capable of doing.
There is plenty of freely available evidence right now which shows that the Sun is actually SOLID. We're talking actual PHOTOGRAPHS here.
That's tantamount to heresy in the pseudo-religious "scientific" world. Try telling that to a bunch of astronomers or astro-physicists and they'll promptly tar and feather you for daring to threaten their comfort zone and upset the mainstream "scientific" apple cart.
But the facts are there to see, for those with eyes to see it - and if the sun is SOLID, then we can toss out any and all theories we might have about what the Sun actually is or how it works - or what it might decide to do at any time.
Suppose that humanity is forced to go underground to survive a Solar Winter or worse, a Solar Furnace? What will we do for energy then? I'd be a whole lot happier knowing that we had more options than just solar or wind power to draw on .
In the meantime, there's nothing so terrible about nuclear power. Actually a very sensible investment, I would think.

Even I don't like it!!
Because it produces the worst waste whcihc is harmful for our health .And scientists are still working on handling the nuclear waste economilcaly and safely!!
But till today no sure shot sucess.And its costly too !!
The radioactive waste can affect the people to great and long extent.
And any mishandleing happens it can cost till generations very dearly of many countries.
So I am not in favour of Nuclear power !!
We should rather go for the wind energy its more cleaner and more economical but I know nuclear power is cheaper but whats the use if it is harming the humanity!!

I think that there are many other alternatives to nuclear power that are much safer, cleaner and less expensive - but unfortunately not as much time, money, resources, or energy are spent in development. These include wind, water, and solar power. The pressure has to come from us - as citizens concerned about our environments to stop the building of nuclear power plans and encouraging other alternatives of power.

Have you read any of the other responses about this? While development is good in those areas (and there is LOTS of development in those areas), they are just not feasible on the large scale because of the massive amounts of space they require (as well as money) for very low percentage return.
