Its called fission.
Uranium-235
It is true that a uranium nucleus splits in the nuclear fission of uranium.
If things go according to plan, the neutron encounters a fissionable atomic nucleus and then undergoes what is called neutron capture. That's the next step in the process. The presence of that neutron in the nucleus destabilizes the nucleus (more than it already is as that nucleus is radioactive and unstable anyway). In an extremely short period of time the instability results in nuclear fission. The nucleus splits.

In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).
In the nucleus of the fuel material, such as uranium-235
Uranium-235
Uranium-235
the splitting of the nucleus into smaller fragments is called fission.This was the same process used when the US dropped its atomic bombs on Hiroshima and Nagasaki during WWII back in 1945 using Uranium in one, and Plutonium in the other.

Basically, nuclear weapons are made from uranium or plutonium material and hydrogen as a chain reaction nucleus.
It is true that a uranium nucleus splits in the nuclear fission of uranium.
To set off a fission reaction (the reaction that occurs in a nuclear reactor), a person must first pump a neutron into a heavy nucleus. So if a neutron is pumped into a uranium or plutonium nucleus capable of undergoing fission, the nucleus splits in two, and releases more neutrons, which hit more nuclei, which in turn send out even more neutrons, thus setting off a chain reaction where every time a neutron hits a nucleus, the nucleus splits in two and sends out more neutrons.
1. Yes, all coals contain traces of uranium. 2. Uranium is not combustible; the "burning" of uranium in nuclear reactors is a nuclear reaction, not a reaction with oxygen.
That is nuclear fission. An example is that of a Uranium-239 atom undergoing beta decay. That is, a neutron in the nucleus ejects and electron, becoming a proton, resulting in Uranium-239 becoming Neptunium-239.
