The standard hydrogen bomb is a Teller-Ulam design which utilizes a Fission-Fusion-Fission sequence.
The primary is a fission device, likely boosted with tritium, not too different from the Fat Man implosion bomb used over Nagasaki; although it is much more efficient. The minimum critical mass for Pu-239 is about 25 pounds (11kg).
The secondary is a fusion-fission device, utilizing the x-ray radiation from the primary to compress & heat a light element. At the center of this is a hollow tube of Pu-239. As the secondary compresses, the Pu-239 tube (aka "spark plug") compresses as well and achieves criticality giving a fission reaction. This may require another 25 pounds (~11kg) of Pu-239.
So a rough estimate is about 50lbs (~22kg) for both fission processes. However, there are ways to create a super-critical mass using less material through the use of neutron reflectors, tritium boosting, neutron-initiators and other methods that are not common knowledge.
Nations that possess nuclear weapons don't give precise details for reasons of national security, so an exact answer to your question would require a security clearance of some sort, and a need to know.
So the best answer to your question is not much more than 50 pounds, or 11kg per weapon, probably a lot less.
What else can I help you with?
Is there plutonium in a hydrogen bomb?
Yes, a hydrogen bomb uses a process called nuclear fusion that requires a small amount of plutonium to initiate. Plutonium is used in the primary stage of a hydrogen bomb to generate the high temperatures and pressures needed for fusion to occur.
How much plutonium was USED in little boy?
The Little Boy atomic bomb used about 64 kilograms (141 pounds) of highly-enriched uranium-235, not plutonium. Plutonium was used in the Fat Man bomb, which used about 6.2 kilograms (13.6 pounds) of plutonium.
What is the difference between nuclear bomb and plutonium bomb?
A nuclear bomb is any bomb with any nuclear or atomic material inside it, while a plutonium bomb is a specific type of nuclear bomb. Plutonium could be the nuclear material inside the bomb, and if it is, it's a plutonium bomb.
How much plutonium used in nuclear bomb?
In the Nagasaki bomb, about 14 pounds. Design criteria on later weapons is classified.
How much plutonium is in an average atomic bomb?
ugh there was 10000kgs in fatman aka 100 sticks
Is hydrogen converted into plutonium in a hydrogen bomb?
No.
What is a uranium bomb?
A uranium bomb is an atomic bomb fueled by uranium-235A plutonium bomb is an atomic bomb fueled by plutonium-239A composite bomb is an atomic bomb fueled by both uranium-235 and plutonium-239A wet bomb is a hydrogen bomb fueled by liquefied deuterium/tritiumA dry bomb is a hydrogen bomb fueled by solid lithium deuteride
Is the nuclear bomb the best bomb?
No, in terms of destruction the hydrogen bomb is the strongest, but if you mean killing the plutonium bomb is the one that does the most killing.
When was the hydrogen bomb dropped?
A hydrogen bomb was not dropped on Japan. It was dropped years later as a test and to determine how it acted in comparison to the plutonium and uranium bombs.
Is there plutonium in a hydrogen bomb?
Yes, a hydrogen bomb uses a process called nuclear fusion that requires a small amount of plutonium to initiate. Plutonium is used in the primary stage of a hydrogen bomb to generate the high temperatures and pressures needed for fusion to occur.
What is the name of a artificial atomic element discovered after the first hydrogen bomb explosion in 1953?
Plutonium
How do you make a atomic bomb on Doodle God?
plutonium + weapon
Was the 'Able' bomb at Bikini plutonium?
Yes, a bomb with plutonium.
How much plutonium was USED in little boy?
The Little Boy atomic bomb used about 64 kilograms (141 pounds) of highly-enriched uranium-235, not plutonium. Plutonium was used in the Fat Man bomb, which used about 6.2 kilograms (13.6 pounds) of plutonium.

Does transmutation help in making a hydrogen bomb?
Transmutation occurs when a fusion bomb (H-bomb) detonates: The Primary (A-bomb/fission) converts a heavy element like plutonium or uranium into lighter elements, such as strontium, etc... The Secondary (H-bomb/fusion part) converts a light element into heavier elements, like Hydrogen into Helium.
How much plutonium would be needed to build a standard hydrogen bomb?
The first plutonium fission bomb used 6.2 kilograms of plutonium.The first stage of a hydrogen bomb is a fission bomb. By using better explosives to compress the plutonium and tritium gas boosting it is probably possible to use 2 kilograms to 3 kilograms of plutonium here.Each fusion stage uses a plutonium "sparkplug" rod that runs the length of that stage to initiate fusion. The exact dimensions (and thus the weight) of plutonium used here is classified Top Secret Restricted Data. It is possible that these "sparkplugs" may even be hollow tubes (to allow neutrons a free path the entire length), which might eliminate more than 90% of the weight of a solid rod while improving its performance.As a "ballpark guess" without reliable data to base it on, each stage of a modern hydrogen bomb (both the fission first stage and all fusion stages) probably uses less than 3 kilograms of plutonium.A standard two stage hydrogen bomb would then use less than 6 kilograms of plutonium and a three stage hydrogen bomb (the largest size ever built) would then use less than 9 kilograms of plutonium.
