If you mean used by humans, this would have been the first H-bomb test, I'm not sure of the date.
Greenhouse George test in 1950, yield 225KTon, verified feasibility by "lighting a fusion match using a fission blast furnace". Probably much less than 1KTon of yield was due to fusion.
Ivy Mike test in 1952, yield 10MTon, erased the island of eugelab in eniwetok atoll. Device was 80 foot tall, 20 foot diameter, 2 foot thick steel case containing triple steel thermos filled with cryogenic liquid deuterium/tritium and an atomic bomb at the bottom below the thermos.
In 1953 the soviets did an H-bomb test, using solid lithium-deutride fuel in the first actual thermonuclear airdrop, but it was a different design that could not yield much more than a few megatons max.
The US Castle Bravo test in 1954, yield 15MTon, on the end of a causeway at eniwetok atoll punched a hole in the outer reef. Device was first solid lithium-deutride fueled bomb using principles of Ivy Mike design. 5MTon of yield was due to a totally unanticipated effect of the Lithium-7 isotope in the lithium-deutride.
Most of the rest of the high yield Castle and 1956 Redwing tests were either done as airdrops or barge tests in lagoon or Ivy Mike crater to limit further damage to the finite atoll landmass. (how considerate)
What else can I help you with?
Which is the first step in the p-p chain of nuclear fusion?
The first step in the proton-proton chain of nuclear fusion is when two protons fuse to form deuterium, releasing a positron and a neutrino in the process.
How do nuclear fusion differ fundamentally from nuclear fission?
Nuclear fusion doesn't produce energy.
How does nuclear fusion power the sun for 10 billion years?
First, the Sun is pretty big, and there is a LOT of hydrogen. Second, nuclear fusion generates a WHOLE lot of energy.
Which do you currently use nuclear fusion or fission?
I currently use nuclear fusion.
Where does nuclear fusion occur in a nuclear plant?
Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.
What is blocking the development of thorium fusion?
Thorium is not a fissile material; the fission with neutrons is not important. Thorium was proposed a as a fertile material.Thorium is not involved in nuclear fusion.
What process produces the largest amount of energy given off by stars?
Nuclear Fusion
Is fusion chemical nuclear or mechanical?
Fusion is a nuclear reaction.
Is fusion nuclear energy or chemical energy?
Nuclear fusion produces nuclear energy
What date did the first fusion generator operate?
The first work on nuclear fusion was performed in 1933 by Ernest Rutherford. The first nuclear fusion "reactor" was built in 1947 by teams in the UK and USSR. To this day no nuclear fusion "reactor" has been able to produce more energy than had to be put into it to get the reaction started, despite many different experiments on many different designs.
What causes lesser pollution - nuclear fission or fusion?
Nuclear fusion
How do nuclear fusion differ fundamentally from nuclear fission?
Nuclear fusion doesn't produce energy.
Which is the first step in the p-p chain of nuclear fusion?
The first step in the proton-proton chain of nuclear fusion is when two protons fuse to form deuterium, releasing a positron and a neutrino in the process.
In nuclear fusion mass transforms into what?
In nuclear fusion mass transforms into energy.
Is strontium produced by nuclear fusion?
No Strontium is produced by nuclear fission not fusion.
Can americium produce nuclear fusion?
Americium was not tested to produce nuclear fusion.
Is the sun a nuclear fusion reactor?
Yes, the sun is a nuclear fusion reactor.
