What particle is used to start nuclear fission?
In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
How much energy is needed to start nuclear fission reaction?
Incomplete question
What processes can be used to start a nuclear fission reaction in certain atoms?
Firing a neutron at the nucleus of the atom.
Which type of nuclear reaction is used in modern-day nuclear reactors?
Nuclear fission is used in nuclear weapons to create what some might call an atomic blast (nuclear blast). Nuclear fission used this way can also be applied in special complex designs to generate enough thermal energy (heat) to initiate a fusion reaction. This creates an even bigger nuclear blast.
Nuclear energy is an alternate energy source produced from atomic reactions?
There are two: Nuclear Fission and Nuclear Fusion. Fission is when a neutron is fired at an element with a high atomic number (usually Uranium) which then splits, releasing energy and more neutrons. this produces a chain reaction, which continues until all nuclei have been split. Fusion occurs in stars and a few experimental reactors, and happens when two forms of Hydrogen nuclei (Deuterium and Tritium) fuse into an unstable nucleus, which in turn splits again into Helium and a spare neutron. Fission can start at any temperature, but Fusion only when Hydrogen is in a plasma state.

What do you have to do to get nuclear energy?
You have to build a nuclear reactor which is an assembly of nuclear fuel and a moderator, which enables a chain fission reaction to start and continue, which releases thermal energy.

What particle is needed to begin a nuclear chain reaction?
Neutrons are the important particles of nuclear chain reactions and the reactions depend on them. The neutrons do not really start the fission, reaction, however, because the neutrons come from fission in the fuel.The material in the fuel, typically a mix of 235U and 238U, undergoes fission spontaneously. When a fission event happens, more neutrons, typically two or three, are emitted. These bounce about from atom to atom, until they cause another atom to undergo fission, releasing more neutrons to increase the rate at which atoms undergo fission.But the neutrons needed for the chain reaction are actually produced by the fuel spontaneously, and these are produce in an ongoing manner with or without critical mass. So it is not a particle that starts the chain reaction; it is the act of putting together a critical mass.
Maximam dengrus bomb between nuclear bomb or hydrogen bomb?
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.

Why are fusion reactors not yet present day reality like fission reactors?
Only beacuse of starting trouble. Any way we need billion kelvin temperature to start with for which we have to rely on fission reaction. One more important point we cannot have a controlled fusion reaction as we do so in fission ie nuclear reactor using control rods.
Why don't the pellets with uranium oxide start to react during the enrichment process?
1. The material for enrichment is the uranium hexafluoride (UF6) not uranium dioxide pellets. 2. For a nuclear fission and and a nuclear chain reaction we need thermal neutrons.
What makes up a nuclear bomb?
Depends on the type of bomb. The first nuclear weapons were fission weapons- they used a heavy metal such as Uranium or Plutonium. These metals, when compressed by explosives, would undergo nuclear fission, and break into lighter elements, releasing heat and radiation. Later, larger bombs were fusion bombs. They used a fission bomb to start the nuclear reaction, but then used that energy to FUSE light elements, such as Deuterium and Tritium into heavier elements, releasing LARGE amounts of heat and radiation.
What elements are made by a nuclear fission reaction?
The only element needed to start nuclear fission is Uranium-235, which is very slightly radioactive but when made into fuel rods and before any use in a reactor can be handled without danger.
