This is hard to compute. The 22 kiloton MK-III Fatman had 6.2 kilograms but of this only a little over 700 grams fissioned. For 1 kiloton you would need roughly 33 grams to fission. But how much more you would need to get the bomb to work reliably depends on too many tricky design details (most classified) to tell. Assuming the same material efficiency as the MK-III, a total of roughly 282 grams would be needed. However this amount is so far below criticality that a superefficient implosion assembly system would be required as well as gas boosting to get that small a yield.
I would guess, without access to classified information, that a basic pure fission 1 kiloton bomb would need between 2.5 kilogram to 5 kilogram of plutonium to fission the roughly 33 grams needed for that yield.
Material efficiency becomes real bad below about about 10 kilotons unless gas boosting is used. Even the MK-IIIs material efficiency of about 10% is low by today's standards, but the figure is still a good starting point, especially as it is not classified.
What else can I help you with?
What is the smallest possible size for a nuclear bomb?
The smallest possible size for a nuclear bomb is typically around 1 kiloton, which is equivalent to the explosive power of 1,000 tons of TNT.
How many kilograms in a kiloton?
There are 1,000 kilograms in a kiloton. A kiloton is equivalent to 1,000 metric tons.
How much weight does a kiloton of TNT equal?
A Kiloton of TNT is not really a measure of weight but of explosive force. A kiloton of TNT would would weigh 1000 metric tons or about 2.2 Million pounds. But a kiloton of water, feathers, bricks.. would also weigh 2.2 Million pounds. A kiloton of TNT has the energy of 4.2 × 1012 joules or 4 Billion BTU's which would be enough energy to raise the temperature of 2 Million tons of Water 1 degree F.
How much is a kiloton of gold worth?
1 Kiloton would be 1000 metric tons or 1000 x 32150746 troy oz or 32150746000 troy oz. If gold traded at $1300 per oz total value of 1 Kiloton of Gold would be 41.796 TRILLION dollars or about 2.45 times the total US National Debt.
How many pounds in 1000 kilotons?
2,000,000 pounds A kiloton is 2000000 pounds I think kilo means 1000 and there are 2000 pounds in a ton so just do the math 1000x2000 and you should have your pounds. CORRECTION!!!!!!!!!!!!! there are exactly 41,887,829.815127 pounds in 1 kiloton. That's roughly 42 million. NO! NO NO Well to be honest 1 metric ton is 1000 kilos witch is 2204lbs 1 kiloton is 1000 metric tons so 1 kiloton is 2.204 million lbs so 10 kilotons is 22.04 million lbs give or take a buick

What is the Plutonium isotope composition of a nuclear bomb?
Typically, a nuclear bomb would use plutonium-239 as the primary isotope for fission. Plutonium-239 is preferred due to its high fissionability and ease of obtaining through processing in nuclear reactors. Small amounts of other plutonium isotopes, such as plutonium-240, may also be present due to the manufacturing process, but the majority would be plutonium-239.
What is the exponential notation for kiloton?
A kiloton could be described as 1 x 103 tons.
How much does a gallon of plutonium weigh?
1 plutonium (solid) gallon = 71,337 kg
What were the bombs filled with that America had dropped on Japan?
There were a great many bombs dropped on Japan, mainly high explosive bombs, and incendiary bombs. The bomb used on Hiroshima was a atomic bomb holding 115 lbs of Uranium 235 (less than 1% of that was used in the explosion). The bomb dropped on Nagasaki was a Plutonium bomb, holding about 13.6 lbs of Plutonium. (about 20% of that was used up in the explosion)
