A nuclear reactor uses either nuclear fission or nuclear fusion to generate electricity, while bio-reactors use the excretions of many animals to generate electricity.
This will be a hydro plant, or a series of them, not nuclear
Depends on the amount of electrical energy they (need to) generate. How much does the average nuclear plant generate ? How much does the average coal plant generate ?
Depending on the size of the submarine and whether it is peace or wartime.U-Boat. 27 -> 57Non Nuclear ~ 40Nuclear ~ 80 (more in wartime)
A typical US ballistic missile submarine has either:24 Trident II missiles, each carrying 1 to 12 warheads4 torpedo tubes with an unknown number of nuclear torpedos24 to 288 missile warheads plus nuclear torpedos154 Tomahawk cruise missiles4 torpedo tubes with an unknown number of nuclear torpedos154 missile warheads plus nuclear torpedosActual numbers for various types of submarine will vary.
305 heads work on a 350 engine
Most submarines now have a single nuclear reactor. Some smaller, coastal submarines have a single diesel.
It depends on the size and type of boat, but in general, between 90 and 130 officers and crew.
