Fast reactors-Fast reactors get their name from the fact that the neutrons released in the fission reaction are not slowed down as in a thermal reactor. Fast reactors contain a minimum of moderating material.A major advantage of this design stems from the fact that more neutrons are emitted during high-energy fission than during low-energy fission. Another important advantage follows from this total destruction of heavy atoms. A fast reactor produces much less long-lived radioactive waste than thermal reactors and ability to produce more fuel than it uses. However, today the vast majority of nuclear power is produced by thermal reactors.

-Safety features in design and operation of fast reactors are mostly similar to those of thermal reactors. Differences are relatively small, tend to favor fast reactors and the engineering solutions are in hand.Waste management is much easier with fast reactors because almost all of the long-lived nuclear waste products associated with thermal reactors are split by the fast neutrons. The radioactive materials remaining are of concern for less than 500 years.In fission reactors using uranium, the process of “burning” nuclear fuel involves production and consumption of plutonium. In a thermal reactor, perhaps 30% of the useful energy comes from fissioning of plutonium. A fast reactor, on the other hand, derives almost all of its energy from plutonium.If fast reactors have such a large fuel economy advantage over thermal reactors, why are there not more fast reactors in use today. First, uranium is so inexpensive today that there is little incentive to use it more fuel efficiently, and storage of the unused uranium and other nuclear waste is manageable in the short term. Second, thermal reactors were first to be introduced commercially and have been continually improved

In the absence of hydroelectric resources: yes. Hydropower is by far the most important renewable. Hydro and nuclear power each produce about 15 percent of global electricity.
Many countries still have tremendous hydro potential. But in some countries—like Germany andUK—they face a choice between fossil fuels and nuclear energy. Germany can keep nuclear energy or become ever more dependent on Russian gas.
The lowest per capita emitters in Europe—Sweden, Switzerland, and France—all have a combination: France is predominantly nuclear, Switzerland is predominantly hydro, and Sweden is about 50-50.

The Malaysia Nuclear Agency (MNA) is a Malaysian nuclear technology research facility located in Bangi, Selangor.
Recently, MINT has been re-branded as Malaysia Nuclear Agency (Agensi Nuklear Malaysia).
Malaysia Nuclear Agency (Nuclear Malaysia) has a role to introduce and promote the application of nuclear science and technology for national development.
Established in 19 September 1972, Malaysian Nuclear Agency was then known as Centre for Application of Nuclear Malaysia (CRANE) before it was formally named as Tun Ismail Atomic Research Centre (PUSPATI).
In June 1983, PUSPATI was placed under the patronage of Prime Minister Department and was called Nuclear Energy Unit (UTN). It was then placed under Ministry of Science, Technology and Environment in October 1990. In August 1994, its name was changed to Malaysian Institute for Nuclear Technology Research (MINT).
On 28 September 2006, following its restructuring, MINT was given a new identity,which is Malaysian Nuclear Agency (Nuclear Malaysia). Its strategic location, near higher learning institutions, besides its close proximity to the National Administration Centre, Putrajaya, and the Multimedia Super Corridor, Cyberjaya, has stimulated Nuclear Malaysia to meet its aspirations.
The rebranding followed mass restructuring of its organisation departments, human resource, and the re-alignment of its core business towards establishing nuclear power in Malaysia as an alternative form of renewable energy.

Malaysian Prime Minister at COP15
However , like many leaders of developing countries, Datuk Seri Najib Tun Razak left the Danish capital, partially satisfied with the outcome of the United Nations Climate Change Conference (COP15) which ended Friday 18th December
The Prime Minster of Malaysia, Najib Razak, delivered Malaysia's proposal to reduce its CO2 emission's to 40 per cent by the year 2020 compared with its 2005 levels, subject to assistance from developed countries. Copenhagen, Denmark. 17/12/2009.
Prime Minster of Malaysia Najib Razak had delivered Malaysia stand to reduce its carbon dioxide emission to 40 per cent by the year 2020 compared to 2005 levels subject to assistance from developed countries.
In his speech at the United Nations Climate Change Conference 2009 at Copenhagen on 17th December, Najib said the cut was conditional upon receiving transfer of technology and adequate financing from the developed world.
United Nations data shows Malaysia's carbon emissions in 2006 stood at 187 million tonnes or 7.2 tonnes from each Malaysian.
However , like many leaders of developing countries, Datuk Seri Najib Tun Razak left the Danish capital, partially satisfied with the outcome of the United Nations Climate Change Conference (COP15) which ended Friday 18th December
The prime minister said although there was greater political commitments shown by leaders of developed nations, including United States president Barack Obama, it had not reached a level to fully address the main issues.

KUALA LUMPUR, Aug 31 — The government is searching for a public relations agency to help build public support for nuclear power, as part of a plan to make the country ready for an alternative energy source by 2013.
The Holmes Report, a New York-based publication that serves the public relations community, reported this week that the Malaysia Nuclear Power Corporation (MNPC), a government body formed in January to spearhead the deployment of nuclear energy, is understood to have shortlisted three firms for the sensitive project.
“It is understood that a formal pitch is yet to take place. A source involved in the process said that fees had not been confirmed, but were expected to be in the seven-figure range,” the report said.
The invitation for an international public relations effort to boost support for nuclear energy could spark controversy after the recent row over reports that Putrajaya paid RM58 million to FBC Media to burnish its international image on various international broadcast channels.
British media regulator Office of Communications (Ofcom) is probing programmes made by FBC Media for the British Broadcasting Corporation (BBC)
It is understood Putrajaya has now ended its contract with FBC Media after an exposé revealed Malaysian leaders routinely appeared in paid-for interviews on global television programmes on CNBC.
The Malaysian Insider understands that the Prime Minister’s Office (PMO) terminated FBC Media’s contract earlier this month, just months after another public relations firm, APCO Worldwide from the United States, met an ignominious end for alleged links to Israel.
Global broadcasters, including CNN and CNBC, have been scrambling to contain any potential fallout after allegations of impropriety surfaced following the exposé by whistleblower Sarawak Report.
The latest plans to launch a publicity campaign for nuclear power also comes in the midst of public concern about nuclear safety, spurred by the ongoing crisis at the nuclear plant in Fukushima, Japan.
According to briefing notes obtained by the Holmes Report, public relations counsel is being sought to ensure that stakeholders are able to make an informed decision about the proposed plan by that date.
“The bottomline: Malaysia has to be nuclear-ready and get [the] mandate of the public by 2013, when the government will make the final decision and reveal the site,” reads the brief, according to the report.
The Holmes Report also said boosting public support for nuclear power to above 50 per cent is a priority, along with managing concerns and issues.
“The brief indicates a substantial research component that will assess public opinion regarding nuclear energy and use these findings to devise a strategy to improve perceptions and support. The appointment is for an initial 24-month period, to be renewed on a yearly basis thereafter,” it said.
Energy, Green Technology and Water Minister Datuk Seri Peter Chin had said in December 2010 that Malaysia plans to build two nuclear power plants that will generate 1,000MW each, with the first plant ready for operation in 2021 and the second plant a year later, as part of the overall long-term plan to balance energy supply.
“Hopefully, by 2013 or 2014, we will able to finish evaluating this. As for calling of tenders, we hope it will be done by 2016,” he told state-news agency Bernama in an interview then.
He said Malaysia was heavily reliant on gas and coal for its electricity supply and it was government policy to reduce dependence on fossil fuel. Gas accounted for 64 per cent of the country’s energy generation while the remainder came from coal.
The country is running out of gas, and a new hydropower project will only provide sufficient power for East Malaysia, and not the remainder of the country.
Besides, Chin said, other sources of energy such as biomass and wind were too minimal while solar was a good potential but the technology was still very expensive.

The fundamental mistake we made was to lump nuclear energy along with nuclear weapons. Everything nuclear was evil. Much of the environmental movement continues to make that mistake. When I left Greenpeace in 1986 I still opposed nuclear energy.
But as climate change emerged it was necessary to rethink energy production. Today, 87 percent of all energy used is fossil fuel energy. To replace that with renewables—intermittent energy like solar and wind power—is mathematically impossible.
But nuclear energy could do it: unlike solar and wind power, it is sustainable economically and in terms of providing continuous power.

This is the thing that's came to people's head when said about NUCLEAR :
SUPER WEAPON RADIOACTIVE
BOMB EVIL
WAR HEAD NUCLEAR MISSILE
this is what u get from Movies or Games..
but have you heard about this :
carbon-emission-free electricity
CLEAN ENERGY
REDUCE POLLUTION
stop global warming
LETS LEARN MORE ABOUT NUCLEAR!
Nuclear energy is one of the many natural resources that we know how to turn into heat and electricity. It is, by far, the most energy-dense of all these natural resources, meaning we can extract more heat and electricity from a given amount of it than from an equivalent amount of anything else. As an example, consider a chunk of coal and chunk of natural (unenriched) uranium, both weighing the same (1 kg) and both mined and isolated straight out of the earth. If we could suck all the energy out of the coal, it would run a 100W light-bulb for about 4 days. With the uranium, we could run the bulb for about 180 years. That’s just using the good kind of uranium, too. If we used a fast reactor and sucked all the energy from the not-so-good atoms in the same block of uranium, the light bulb could burn for 24,000 years. This kind of energy density eliminates huge amounts of the environmental footprint required to use less dense fuels, such as huge coal mines, massive gas and oil fields, trainloads of fuel shipments, and expansive wind or solar farms. Oh, and nuclear reactors do this all without releasing any pollutants into the environment!

Wow. So why do we still use coal, or anything else for that matter?
When nuclear energy hit the streets in the 1940s (after being developed as a weapon), it was infamously claimed that electricity would be too cheap to meter. Obviously that hasn’t happened. Why not?
The reactors that we have designed and built so far to split atoms and release the energy are mostly large, complicated, and expensive. Once built, reactor operation costs very little (buying a few tonnes of uranium every 4 years is much cheaper than buying weekly trainloads of coal). But the way modern investor-return markets work, high capital costs matter more than the big picture. The high cost of constructing nuclear reactors has caused much financial trouble for nuclear energy, even though the long-term economics looks good.
As you learn more about nuclear energy, you will find that there are good solutions and answers to all of the concerns. It’s a known technology capable of producing 24/7 carbon-emission-free electricity in magnitudes not only able to displace fossil fueled power generators but also to power the transition from gas to electric vehicles with fuel reserves that can last humanity well into the tens of thousands of years (with breeding, of course). It stands tall in a room with king coal, foreign oil, and the intermittent renewables, and has good responses to harsh criticism. While certainly not perfect, nuclear fission is capable of responsibly providing us with a large chunk of the energy we need.

Nuclear plants have a high capital cost but a very low operating cost. There is a lot of risk up front but once the plant is running, over the 60-80 year lifespan it more than pays for itself. In Germany, brown coal costs 2.4 euro cents per kilowatt hour, nuclear costs 2.5 cents.
The anti-nuclear folks are trying to scare the public into thinking their electricity rates will go up if we build nuclear. That is comical as the wind and solar they champion costs between 3 and 20 times more than nuclear.
