They do. In those plasmas which don't fly apart there are other factors. In plasmas for fusion power, the plasmas are constrained by magnetic forces which keep the material in proximity.
There is also the strong nuclear force. This is a very strong force, with a very short range. If two positively charged nuclei can be forced close enough together, then the strong nuclear force, which pulls them together, will become more powerful than the electromagnetic force, which pushes them apart. Then they form one nucleus, and spit out a lot of energy, and sometimes a neutron.

Do charged nuclei repel each other in a plasma?
Yes , but they are not allowed to move apart by powerful forces containing the plasma. In man-made apparatus, this would be magnetic forces.
What is plasma the ionized gas?
Plasma is a gas where the "temperature" is so high that all the electrons have been removed from the atoms, leaving just the positively charged nuclei and free electrons. There can be no molecules in a plasma as without electrons the bare atomic nuclei repel each other.
What keeps atoms from fusing together?
It is the nulei which fuse. Nuclei are positively charged and thus repel each other. The kinetic energy of the nuclei must be very large for nuclei to be able to fuse, such as at the surface of the sun, where hydrogen nuclei fuse to form helium nuclei.
Why is extremely high pressure required to cause atomic nuclei to crash into one another stars?
The nuclei of atoms include one or more protons, which are strongly charged. It is necessary to use heat or kinetic energy, or some other energy, to overcome the charge.
Why do two objects repel each other?
anions (negatively charged objects) repel cations (positively charged objects)

Why did nuclei fuse together?
Basically because both nuclei are positively charged so repel each other.
Why do protons in an atom not separate?
Being positively charged, particles protons should repel each other but they are held together in the nuclei of atoms.

Why does nuclear fusion bring nuclei extremely close together?
Because the nuclei are all positively charged they repel each other. They are made to stick to each other when brought close enough for the strong force to take hold.

What is plasma gas?
Plasma is a state of matter different from ordinary gas. In a plasma the atoms are ionized and thus electrically charged, causing them to repel each other (significantly changing the compression/expansion properties from those of gasses) and making the plasma electrically conductive and respond to magnetic fields (which gasses do not).
Describe How the nuclear force affects the composition of a nucleus?
The strong nuclear force holds atomic nuclei together, and it must be very strong to overcome the tendency for protons to repel each other. Protons, as you'll recall, are positively charged, and like charges repel.
What do like charged ions do?
Like-charged ions repel each other. Opposite-charged ions attract each other.
