Plenty of cheap fuel, and no radioactive waste.
Fusion reactors produce less radioactive waste compared to fission reactors. Fusion reactors use abundant sources such as deuterium and lithium for fuel, while fission reactors use limited sources like uranium. Fusion reactions release more energy per unit mass of fuel compared to fission reactions.
Most nuclear power plants currently operating in the US are classified as pressurized water reactors (PWRs). These reactors use water as both a coolant and moderator to generate electricity through nuclear fission. PWRs are the most common type of nuclear reactor in use worldwide.
Modern day nuclear reactors primarily use fission reactions, where the nucleus of an atom is split into smaller fragments, releasing large amounts of energy. Fission reactions are controlled in reactors to generate heat, which is used to produce electricity.
Nuclear reactors use controlled nuclear fission reactions to generate heat, which is then used to produce steam that drives turbines to generate electricity. The heat is produced in the reactor core where nuclear fuel rods containing uranium or plutonium undergo fission reactions. The reactor's cooling system helps regulate the temperature and prevent overheating.
If you mean why are all current nuclear power plants fission reactors, this is simply because the creation and control of nuclear fusion reactions on a scale and level suitable for commercial purposes are not currently well-understood. Experimental reactors can create and hold a plasma for a short period, and sometimes realise a small net gaing in energy, but none currently can run for an extended period. They are also technical challenges remaining around containment of the plasma and degradation of the plasma vessel due to neutron damage. The current wisdom among fusion researchers is that "commercial fusion power has been 50 years away for the last 50 years...."
It is very expensive, and it is hard to keep up

We use nuclear fission in nuclear reactors to tap nuclear energy.
No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
Nuclear reactors use nuclear fission.
There are two primary design styles of fission reactors to produce electricity. Pressurized, and Boiling water reactors.
In nuclear fission reactors
there is no such thing.
No, nuclear fission operates all nuclear reactors. If they are power plant reactors it is used to generate electricity.
Nuclear fission is the working principle under which the nuclear reactors operate.
Nuclear fission occurs in fission reactors, a type of nuclear reactor, and in fission bombs, more commonly knows as atomic bombs.
Uranium, plutonium or thorium (for fission reactors, by far the most common type).
