India’s first fast breeder reactor to generate power 2015-16

[OrionHunter]

And that is sufficient to make 30 Nuclear bomb each reactor or fuel our nuclear sub or Aircraft career. 10 reactor means 300 Nuclear bomb fissile materials per year from Fast breeder reactor per year. This is simply great.

How many bombs can one make with the available fissile material?

The minimum mass of fissile material that can sustain a nuclear chain reaction is called a critical mass and depends on the density, shape, and type of fissile material, as well as the effectiveness of any surrounding material (called a reflector or tamper) at reflecting neutrons back into the fissioning mass. Critical masses in spherical geometry for weapon-grade materials are as follows:
Uranium-235 Plutonium-239

Bare sphere: 56 kg 11 kg
Thick Tamper: 15 kg 5 kg

The critical mass of compressed fissile material decreases as the inverse square of the density achieved. Since critical mass decreases rapidly as density increases, the implosion technique can make do with substantially less nuclear material than the gun-assembly method.

The "Fat Man" atomic bomb that destroyed Nagasaki in 1945 used 6.2 kilograms of plutonium and produced an explosive yield of 21-23 kilotons [a 1987 reassessment of the Japanese bombings placed the yield at 21 Kt]. Until January 1994, the Department of Energy (DOE) estimated that 8 kilograms would typically be needed to make a small nuclear weapon. Subsequently, however, DOE reduced the estimate of the amount of plutonium needed to 4 kilograms.

Some US scientists believe that 1 kilogram of plutonium will suffice.

Exactly,

That is why I have taken the figure of 5 KG of Fissile material per bomb. With boosted fission, the yield can be increased substantially. Our hydrogen bomb was ignited by boosted fission.

Fast breeder is an unique technology which generates more fuel than it consumes.

Great thing

Sad that present day Indians could not salvage the unlimited nuclear fusion energy technology blueprints from their ancient Vedic Hindu ancestors... All burnt in one of the wars of the Mahabharata.

Don't worry we have enough for you and world. another non-productive post from sr member.

why most of poster talk non-sense in age to Sci & technology.

nonsense... nuclear power is 50's technology... obsolete and dangerous.

while elon musk has been demonstrating potentially decentralized electricity through the tesla "powerwall", here is indian establishment in its plodding ways doing what shouldn't be done.

the indian power crisis is a political one, to be solved mostly politically and not technologically... there are many useless structures that consume electricity... the 500,000+ temples and the hundreds of thousands of prayer houses of other religions, degree colleges, private banks, the software industry, stock brokings etc... these must be shut down or taxed heavily.

isn't fukushima enough example??
