Iran post threat with it secret facility of producing nuclear bomb. Currently Iran is on the way to build enrichment facilities. From the facilities, their secretly build nuclear weapons. American and European officials believe Tehran is planning to build nuclear weapons. Iran's leadership says that its goal in developing a nuclear program is to generate electricity without dipping into the oil supply it prefers to sell abroad and provide fuel for medical reactors. The actual reason behind this nuclear bomb is:

• Iran scared of the fact that 5 out of 9 world's nuclear power are nearby or on its border
• Iran adopt nuclear hedging (protection security) by maintaining nuclear weapon as option to remain with nuclear treaty or agreement.
• attempt to become more self-reliant in arms and technology facing Iraq which has chemical weapon and nuclear weapon program.

Myself believe that Iran just trying to survive from nuclear threat from the border countries such as Iraq. The middle east country continuously post nation threat and create most of political issued by launching missile against them self. In order to survive, Iran choose by developing nuclear weapon. It is understanding if Iran just want to protect itself from being nuclear victims. However, their act toward nuclear weapons is not a correct ways in gained a solutions. This can lead more disasters than the solutions. Hence, nuclear bomb should NOT be a SOLUTION! Even Washington against Iran for developing secret facilities for preparing nuclear bomb. It is a fear to world security. Therefore, I against the Iran for nuclear weapons! Nuclear weapon does not solve anything but it can create WAR.. WAR..WAR people. Who knows maybe it can lead to WORLD WAR III..

Comparison Of Fossil Fuel and Nuclear Power 1:00 PM

There are lots of resources in generating energy to power up our daily live. The increase in the demand of energy has put a lots of challenges to fulfill the required needs in the century. Lots of consideration and comparison has been done to gain knowledge in generating energy. The table below are premised on the assumption facilities run with reasonable attention to environmental protection so far as routine operation and concern of waste management.

** Question has been raise about the effect of krypton- 85from extensive reprocessing necessary for a breeder reactor system  on  cloud formation and hence potential climate change. However krypton- 85 can be removed from exhaust gases by cyrogenic cooling.

Largest Explosions In Modern History 3:30 PM

First time when I've heard about nuclear is when someone mention nuclear bomb. And that phrase "nuclear" poked my interest to look into few largest most destructive explosion ever recorded in human history.

• Simple math and facts (in tons of TNT)
• Little Boy – 13 to 18 kilotons (exploded at Hiroshima during World War II)
• Fat Man – about 21 kilotons (exploded at Nagasaki during World War II)
• Tsar bomb – 50 megatons (most powerful nuclear bomb ever detonated). A three-stage H-bomb uses a fission bomb primary to compress a thermonuclear secondary, as in most H-bombs, and then uses energy from the resulting explosion to compress a much larger additional thermonuclear stage. It compromise of 3-stages which resulted most powerful nuclear explosion man ever made. 
• Krakatoa -  this one is not man made of course! But the explosion is considered to be the loudest sound ever heard in modern history (heard over 4,000 km away). The eruption was equivalent to 200 megatons of TNT. The volcano exploded in 1883, it killed more than 40,000 people.

Apparently mother nature rocks! Don't you think so? Here's a video of Tsar Bomb explosion.
