There are alternative nuclear technology that are safe and can sustain for a very long time, see this company called http://www.terrapower.com they have the concept called travelling wave reactor which works by processing u238 instead of u235 which is used in conventional nuclear technology

Interesting technology! Suddenly all the nuclear waste from regular enrichment process is useful as fuel. Given the energy to waste ratio of this technology may be its even possible to dump the waste on moon :-) But its still in conceptual stage and can be more than a decade away.

Is fusion a better answer? Or solar, wind, wave power?

Praveen Baratam, Maven - 2 years ago Edit
@Barney - Fusion is a future possibility. We can discuss it when it becomes a reality. Coming to rest of the available choices, it will be a mix and match and the overall goal should be to lessen our energy consumption. In short energy should become much more expensive to encourage sensible consumption. Reduced energy needs will reduce our impact on the Environment.

Mining a radio active material is highly risky and unsafe .My opinion is yes it is a risky operation but we do have many techniques to make the mining most safe as possible, i think large amount of energy @ that risk is good .so what do you think about it .....should we start more radio active mining or to stop the existing mines in ???

Can we afford to stop mining Uranium? What alternatives do we have other than Coal? Is mining and burning coal safer? More practical agenda would be to make Uranium mines even more safe for workers as well as surrounding populations. But can governments actually enforce these policies?

@ Sravan-A question on mining, in the 1980's there were a series of mines opened in the upstate in the mountain range in South Carolina, now the companies are pushing for the use of Sodium Cyanide pooling to get the remaining basically dust, out of each mine. I feel this is unsafe, and incredibly ill advised, is that just my natural reaction at the word Cyanide?

TerraPower Nuclear Technology as discussed earlier has tremendous potential and is a fourth generation nuclear reactor technology.

Its a form of Breeder Reactor that not only produces fissile material from abundant fertile material (U238) but also burns it in the same cycle with out requiring any reprocessing.

Advantages:

1. Technology cannot be exploited to build nuclear weapons.
2. Far more abundant and readily available raw material.
3. Requires no human interference to manage the reactor.
4. Breeder bed reprocessing not required.

May be nuclear power will one day emerge as the panacea to this ailing energy hungry world!

India and many other countries are facing acute power shortages for decades now and there are very few alternatives to coal for affordable energy. I doubt if even coal is affordable anymore. But the real question is what do developing countries have with them, to trade with these research firms, for cheap access to these technologies when they are ready?

Praneeth Baratam, Evangelist - 5 years ago Edit
@Praveen, I think developing countries like India and China definitely have a lot to trade with the companies like Terrapower. Firstly, since these are breeding technologies needing diplomatic, financial and land to conduct their research which in my opinion, developing countries have in required amounts. Its easier to earn diplomatic and popular support in such countries given some lack of awareness among common public (it depends on how the political community drives it).

And China is leaving no stones unturned. It already has Molten Salt Reactor research going on in full scale.

China is totalitarian and can pretty much pursue anything that the communist party deems appropriate. Where as India has a sensitive situation at hand. Abysmal research budget, unstable political climate, gullible citizens who can be led to believe anything by warring political parties, etc. almost lock the policymakers in a stalemate. There is nothing that India can give to these efforts and we will have to cough up heavy premiums when these technologies ultimately mature.

US Geological Survey (USGS) says that India had 30% worlds Thorium reserves.This can be effectively utilized to produce the the energy.If this is implemented effectively then India can play a good role in generating energy from thorium and set an example to the rest of the world

Liquid Fluoride Thorium Reactor (LFTR pronounced "Lifter")
One comment
 
Praneeth Baratam, Evangelist - 5 years ago Edit
India is definitely making a stride in the right direction. Apparently, India has been perfecting a technology called AHWR (Advanced Heavy Water Reactor, using Thorium as its fuel) at the BARC (Baba Atomic Research Center) over the last decade and their efforts are ready to bear fruit. A AHWR is being planned to be constructed in Maharashtra or Tamil Nadu by 2016. While this may not be as safe as a LFTR (Liquid Flouride Thorium Reactor), it is a giant leap for India toward energy independence.

Liquid Fluoride Thorium Reactors (LFTR) - Safe & Cheap

LFTR was also invented by Alvin M. Weinberg, who pioneered Light Water Reactor (most common nuclear reactor) and has much better safety profile than any other civilian nuclear power technology. The greatest advantage with Thorium is that it is abundant, has better chemical and physical properties and yields more usable power than Uranium.

Mr. Weinberg as head of Oak Ridge National Laboratory, USA, demonstrated in the 1970s that LFTR is a much better technology for power generation while LWR is complicated and unsafe.

This is one thing that our former President and Scientist APJ Abdul Kalam has been talking for many many years in India, http://articles.timesofindia.indiatimes.com/2007-04-27/europe/27879135_1_energy-independence-thorium-nuclear-power http://www.rediff.com/news/2006/mar/08prez.htm

Mr. Kalam's vision for Thorium fuel seems to be hinging over Fast Breeder Reactors, which are dangerous. They require reprocessing of highly radioactive breeder bed to recover U233 for further use. The goal should be to develop Once Through Thorium Fuel Cycle where Thorium is burnt in-situ.

Nuclear power is the use of sustained nuclear fission to generate heat and electricity. All the countries in the worlds are racing to use nuclear energy to generate power including India. World did not forgot the Chernobyl Disaster in 1986. After many nuclear disasters post Chernobyl disaster world realized that we cannot prevent any nuclear accident to happen and the recent Tsunami which created a scare among the international. This accident resulted in stopping of nuclear reactors that were affected by the accident. After one year the reactor was again started but was welcomed with the protests across Japan stating that cost of lives is greater than cost of economy.

While nuclear power is projected as cleaner than Coal powered plants there are many issues related to nuclear waste disposal, safety and national security. Given the current state of affairs, nuclear power can prove to be a very expensive alternative to coal in developing countries.

While renewable power sources are being investigated its a fact that they are unreliable and cannot just replace all sources of power. We need to dedicate resources for R&D in Nuclear Power Technology as coal even if its acceptable for now is suicide in the long run.

We need to understand the implication of nuclear accident in India which is most densely populated and it may prove too costly to handle any accident. Recent protest by the locals near Kalpakkam nuclear plant only shows the pain people living there are showing. Let’s support the movement and say no to nuclear energy and Government should consider more other options which are safer and cleaner.

From human capability wise we might be at same level as the primitive human who controlled fire, we are trying to control and mend nuclear power without having all the capability to handle it when a disaster happens. Even today with all advancement controlling fire is no easy job for human.

If this technology is fallen into the hands of terrorists, it will result in unimaginable disaster. Never know how many can be affected by it and future of thse will be unimaginable.

Nuclear technology is too complex to handle unless it is state sponsored terrorism. What extremists might want is a grip on nuclear war heads. R&D in nuclear technology is important and should not be interfered with.

Rightly said Praveen, extremists want nuclear warhead and not fundamental science, R&D on nuclear technology is a necessary for our country.
