Modern submarines are powered by a nuclear reactor. Others are powered by diesel engines while they are on the surface and batteries while they are submerged. The older ones that were powered by diesel and batteries had their limitations. While they were on the surface running on diesel engines they left a trail of exhaust smoke which gave away their position. When they were submerged and running on batteries they could only last so long and then they had to come to the surface, run the diesel engines and recharge the batteries. The submarines that are run by nuclear power do not have to resurface for a very, very long time.
The world's first atomic powered submarine was the USS Nautilus.

new subs are nuclear powered
The USS Nautilus (SSN-571) was the world's first operational nuclear-powered submarine.
A nuclear powered submarine can remain submerged for as long as it has fuel rods and supplies for the crew.
Most people would use the abbreviation 'sub.' The US Navy uses the prefix SS to indicate a submarine. If it is SSN, it would indicate a Nuclear Powered submarine and SSBN would be a ballistic missile nuclear powered sub.
