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.
