3 advantages nuclear fusion has over nuclear fission?
Nuclear fusion produces significantly more energy per reaction compared to nuclear fission. Fusion fuel sources are more abundant and easier to obtain than fission fuel sources. Fusion reactions do not produce long-lived radioactive waste like fission reactions do.
Why is a fission bomb needed as part of an hydrogen bomb?
Yes, in two or three places depending on the design used:the atomic fission bomb primarythe plutonium sparkplug rod that runs through the center for the length of the secondaryif present the uranium tamper that surrounds the secondary inside the hohlraum, if a material other than uranium (e.g. lead, tungsten) is used for the tamper then no fission happens in itIf additional stages (e.g. tertiary, quaternary,...) are present in the design, repeat numbers 2 and 3 for each additional stage to get all the places that fission is used.
Why is fusion preferred over fission?
Fusion is preferred over fission because it produces more energy with less radioactive waste and is less prone to accidents. Fusion reactions use isotopes of hydrogen, which are abundant and non-radioactive, as fuel. Additionally, fusion does not produce long-lived radioactive waste like fission reactions do.
How strong are the nuclear bombs made today compared with the atomic bombs you dropped on japan?
In very round figures modern fusion bombs have yields in the range from 200 kilotons to 400 kilotons with a small number over 1 megaton. The two fission bombs dropped on Japan were 15 kilotons & 22 kilotons respectively.
Which type of nuclear weapons is more explosive and why?
Fusion based explosives can reach higher yields than fission based explosives because there is no theoretical limit to the amount of fuel that can be used in them. Fission based explosives are limited to 500 KTon to 1 MTon yields because of the issue of premature criticality, which usually would cause a fizzle melting most of the bomb and causing dispersion of the bomb material. Fusion based explosives have been built with yields over 50 MTon. However most modern bombs are not pure fission or fusion, but are designed as some mixture optimized for the application. There are some fusion bombs built with very low yield.
Briefly how does a hydrogen bomb works and how it is different from an atom bomb?
In short A-bombs use nuclear fission, H-bombs use nuclear fusion. An atom bomb is more commonly a reference to fission bombs which release energy through nuclear fission. Fission is the the chain reaction in which unstable nuclei such as in uranium break down when hit by a neutron (from another breaking down nucleus) Hydrogen bombs on the hand use nuclear fussion is which two hydrogen nuclei are forced together to form helium and release energy. This is the reaction that occurs in stars and it more powerful. H-bombs as a result of their fuel are "cleaner" as they release energy but less nuclear fallout (radiactive material left over)
Describe three advantages nuclear fusion would have over nuclear fission.?
1. Unlike fission, during fusion tremendous amount of energy is liberated. Hence fusion of a very small mass generates large amount of energy. 2. Unlike fission the products of fusion reactions are not radio-active. Thus they are harmless and can be replaced easily. 3. Highly penetrating radiations are liberated during fission, which are highly hazardous.

Who powerfull in atomic bomb and nuclear bomb?
Atomic bombs and nuclear bombs are technically the same thing: bombs that get their energy from the atomic nucleus.However there are two different processes for getting this energy: fission and fusion. Fission splits large nuclei into smaller ones, fusion joins small nuclei into larger ones. Both release energy from atomic nuclei.Fission bombs are limited to a maximum yield of 500 KTon to 1 MTon, because if you put too much fuel in them they will be supercritical before you even want them to detonate and they will fizzle, giving negligible yield instead of the desired very high yield.Fusion bombs have no such problem and can be made with as high a yield as desired, only limited by the capacity of the delivery vehicle.However modern nuclear weapons are rarely made pure fission or fusion. They are instead made some mixture of both to meet mission requirements, delivery vehicle capability, and production costs. It has also been shown that bombs with yields over about 400 KTon rarely have practical military value, lower yield bombs do more damage per ton of yield than higher yield bombs do.
Why are thermonuclear bombs called dirty bombs?
They aren't usually. However there are 3 variant designs of fusion bombs:High yield - this is the conventional design using either depleted uranium or natural uranium for the tamper of the fusion stage(s). Over 90% of the yield is produced by fission in the tamper caused by 15 MeV fusion neutrons. As nearly all the yield is fission their fallout is roughly proportional to that of pure fission bombs of the same yield (if pure fission bombs of that yield were possible).Clean - this is a reduced fallout design that sacrifices some yield by using inert materials like lead, tungsten, iron, etc. for the tamper of the fusion stage(s). Over 95% of the yield can be produced by fusion. Total fallout would be only a tiny fraction of that of a pure fission bomb of the same yield (if pure fission bombs of that yield were possible).Dirty - this is usually referred to as an enhanced fallout bomb instead of a dirty bomb, like the clean design it sacrifices some yield. In these some or all of the uranium tamper would be replaced by materials with large neutron capture crosssections that become "activated" on absorbing a neutron. Some possible materials that have been proposed at various times are cobalt, gold, silver. 95% or more of the yield might be fusion. Total fallout would be much greater than that of a pure fission bomb of the same yield (if pure fission bombs of that yield were possible). Due to their limited military value, no country is known to have built or stockpiled any. The cobalt bomb was a common idea in fiction stories of the 1950s though, to frighten readers.The term dirty bomb has come to refer mostly to radiological weapons: a conventional explosive enclosed in hot radioisotopes that are dispersed when the explosive detonates. These have severe practicality problems and will likely kill anyone attempting to use them before they could set it up.
What is the advantage of a hydrogen bomb?
The advantage of a hydrogen bomb is its immense destructive power due to the fusion reaction it utilizes. Hydrogen bombs are significantly more powerful than atomic bombs, as they can release exponentially more energy. This makes them a potent deterrent weapon in the context of nuclear deterrence strategies.
