The reflector in a nuclear weapon core is made of a material which can reflect neutrons from fission in the core back into the core, instead of wasting them. A tamper can permit a smaller mass of nuclear fuel (an unreflected subcritical mass of nuclear material can quickly become critical if a reflector is used). Depending on the material, they can also have a neutron-moderation effect. The tamper in many nuclear weapons is also the reflector.

What is the difference between an hydrogen bomb and a nuclear bomb?
The term atomic bomb, nuclear bomb, and hydrogen bomb are confused/confusing. Atomic bomb and nuclear bomb are generic and basically mean any bomb powered by atomic/nuclear energy fission or fusion. Hydrogen bomb specifically means a bomb powered by fusion. Some specific variants, using correct terminology are:Fission bomb, a bomb fueled by uranium and/or plutoniumFusion bomb, a bomb fueled by hydrogen isotopes (however most fusion bombs 90% of their yield is actually still due to fission of uranium-238 in the radiation casing surrounding the fusion fuel assembly.)Boosted fission bomb, a fission bomb with a hollow sealed core filled with tritium gas. When the fission bomb is detonated the temperature/pressure ignites tritium fusion in the gas, which produces an intense flash of high energy neutrons causing additional fission in the (now vapor) fissile core material, boosting the yield.Neutron bomb, a fusion bomb using a neutron transparent material for the radiation casing instead of uranium-238. A neutron bomb typically has only 10% the yield of a similar design standard fusion bomb but has much less fallout, but kills by prompt neutron radiation instead of blast and fire.etc.
How is an atomic bomb triggered by nuclear fission?
You mean what triggers the fission chain reaction? The atomic bomb that was dropped on hiroshima was a gun style fission bomb that used a uranium-235 core. The core consisted of two hemispheres of U-235 on each side of a tube, with an explosive that would push them together. When they collide, they reach the critical mass for an uncontrolled chain reaction and nuclei start to split and release neutrons which will collide with other nuclei and split them as well. The explosive used to trigger the reaction is triggered by a detonator.
How is nuclear fusion used in an atomic bomb?
fusion can be used in several ways:external electronic neutron sources, uses a miniaturized particle accelerator with tritium gas to produce a burst of neutrons to initiate fission at the best time for desired yieldboosting, injects a controlled amount of deuterium and/or tritium gas into a hollow core, when the device is detonated this undergoes fusion producing a large burst of neutrons increasing the fission efficiency; this permits either a reduction in amount of fissile material required or an increase in yield or both; this also permits dial-a-yield bombs having selectable variable yieldstaged fusion, a bomb permitting unlimited theoretical yield; also commonly called the hydrogen bomb
What is layer of lead around the core of a nuclear reactor?
The layer of lead around the core of a nuclear reactor is known as the reflector. It helps to reflect neutrons back into the core, increasing the number available for fission reactions. This contributes to the overall efficiency and effectiveness of the reactor.
How hot is the atomic bomb?
The core of an atomic bomb explosion can reach temperatures of several millions of degrees Celsius, similar to the temperature at the center of the sun. This extreme heat is generated by the rapid release of energy from nuclear fission or fusion reactions.
What type of bomb did us bomb japan with?
Two atomic bombs, a gun-triggered uranium fission bomb, and a plutonium-core trigger fission bomb.
What is the procedure to make atomic bomb?
Uranium or plutonium is enriched to create to create a core capable of nuclear fusion and fission.
What is a booster bomb?
A boosted fission bomb is a bomb with a hollow core filled with tritium gas (sometimes deuterium or a mix of both is used). Shortly after the bomb is fired, the fission heat causes fusion in the gas filling. Neutrons from the fusion cause more fission in the core, boosting the fission fuel efficiency and thus the yield.Sometimes boosting is used for "dial a yield" bombs. By varying the amount of gas in the core (supplied by a canister of gas outside the core) it is possible to get different yields from the same bomb.

What energy is found in a nuclear bomb?
That depends on the type of bomb. An uranium- or plutonium-based bomb operates by splitting the atoms apart, releasing vast amounts of energy in the process. This is known as atomic fission. A hydrogen bomb works by forcing the individual atoms together to form heavier elements such as helium, which releases even more energy. (And with less radiation, too!) This is called atomic fusion, and is how stars like our sun generate their power. (Modern fusion bombs also have a small fission bomb at their core, to generate the high heat needed to start the fusion process.)

Is the atomic bomb the most powerful bomb in the World?
No. The hydrogen bomb is the most powerful bomb in the world. The first atomic bombs split atoms of Uranium and/or Plutonium. Later development in theory and technology have made the Hydrogen bomb possible. This is in fact a 'normal' atomic bomb with a core of hydrogen. When the Atomic bomb goes off, this create an immense pressure on the hydrogen. This pressure (and heat) causes a fusion reaction of Hydrogen atoms. A 'relatively' small atomic bomb can trigger a quite large payload of hydrogen fusion material. Further developments of this massive destructive weapon has been to implement yet another core with radioactive material filled with more hydrogen. This inner core get super compressed by the first explosions, something of which drastically adds to the speed of material being consumed. Explosion being amplified tenfold. All such powerful devices are named 'nuclear' devices or nuclear bombs. Some are mostly a fission bomb, and others are mostly a fusion bomb. The fusion bombs are more powerful than fission bombs alone when comparing size and weight of 'stuff that go boom' Both fission and fusion bombs are considered atomic bombs, and their kind is among the most powerful devices known to man today. In theory, it should be possible to make an Antimatter payload. Something like a few grams could rival the energy released by the most powerful bombs today.
What was the nuclear core of the atomic bomb?
fissile material: highly enriched uranium or plutonium
Does a hydrogen bomb contain uranium?
Yes, a Thermonuclear Weapon (or Hydrogen Bomb) contains a core of Plutonium-239 and Uranium-235. A hydrogen bomb (thermonuclear fusion device) is triggered by a conventional thermonuclear fission bomb, and therefore has a core of fissionable materials such as U-235 and Pu-239. The fission device acting as a trigger is in turn triggered by conventional chemical explosives.

What is the difference between a atomic bomb and a nuclear core?
An atomic bomb is a complete deliverable bomb, including all nonnuclear components. The nuclear core is a rather small part, typically between 2 to 3 inches in diameter that contains the fissile fuel that when made supercritical by conventional explosives in the bomb fissions and provides the energy to drive the actual nuclear explosion.
