Submarines are powered by diesel fuel (in the past) or more recently by nuclear reactors. Nuclear reactors provide advantages in range and in noise produced.
there are no bad things about the nuclear power reactors

In nuclear reactors
Nuclear reactors provide electric power without using oil or coal, so to that extent they do conserve these resources
No, at least not for power reactors
There are currently (year 2013) 31 countries having nuclear power reactors. The rest are not having nuclear power.
No, they don't. All Pakistan nuclear power reactors are imported from outside.
No substitute for nuclear power reactors especially if there is no available fossil fuel.
No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
France (having 58 nuclear power reactors and one under construction) with around 80% of its electricity is produced by nuclear power.
Sweden currently has 3 active nuclear power plants with 10 reactors.
