That's really two questions,
"What are the uses of Nuclear fission reaction?" and
"What are potential uses of nuclear fission?".
See the "Related questions" below for answers to each question.
nuclear fission
Nuclear weapons
No, they rely on fission. Controlled fusion is the holy grail of nuclear power.
The Bataan nuclear power plant uses nuclear fission as the nuclear reaction to generate electricity. In nuclear fission, the nucleus of an atom is split into two smaller nuclei, releasing a large amount of energy, which is harnessed to produce electricity.
A fission nuclear power plant uses nuclear fission reactions to generate heat. In this process, the nucleus of an atom is split into smaller nuclei, releasing a large amount of energy in the form of heat. This heat is then used to produce steam, which drives turbines to generate electricity.
Nuclear fission can be used in destructive ways, such as in atomic bombs where a chain reaction is initiated to cause a powerful explosion. Additionally, nuclear fission can be used in nuclear reactors to produce energy for electricity, but if not controlled properly, accidents like meltdowns can occur, leading to environmental and health hazards.
The most popular use is of Uranium 235 isotope which is used in nuclear fission which helps create nuclear energy.
An atomic bomb uses nuclear fission at the atomiclevel to detonate several tons of explosives.
One use is in nuclear power plants to produce steam and turn turbines to generate electricity.Nuclear bombs ^.^
If you are asking which has the maximum danger, a hydrogen bomb is one type of nuclear bomb. In general, nuclear bombs can be fission (called atomic) or fusion (hydrogen) A fusion bomb is larger than an fission bomb, and actually uses a fission bomb to start the fusion reaction.
This is not correct. Assuming "Using Nuclear Energy" means using it to generate electricity in a reactor. A nuclear reactor is a power plant, that uses nuclear fission to eventually generate electricity. An atom bomb also uses nuclear fission to generate energy causing an explosion. However, due to fundamental differences between the two a nuclear reactor cannot explode like an atom bomb.
A nuclear reactor uses either nuclear fission or nuclear fusion to generate electricity, while bio-reactors use the excretions of many animals to generate electricity.
