Okay, so remember how we talked about nuclear power before? Well, sometimes we need that nuclear energy to power things other than just big power plants. That's where nuclear auxiliary power systems come in.
You can think of nuclear auxiliary power systems like little power plants that are designed to help run things like submarines, aircraft carriers, and even spacecrafts. These systems use a small amount of nuclear fuel to produce electricity that can be used to power all sorts of different equipment.
Now, when we're talking about nuclear auxiliary power systems, there are a few different types that you might hear about. One common type is a radioisotope thermoelectric generator, or RTG for short. An RTG works kind of like a big battery and can keep producing electricity for a really long time, even in harsh environments like space.
Another type of nuclear auxiliary power system is called a pressurized water reactor, or PWR. This is a bit more complicated, but basically, it uses nuclear fuel to produce steam, which then spins a turbine to generate electricity.
There are also other types of nuclear auxiliary power systems out there, but no matter what type it is, they all have to be very carefully designed and operated to make sure that they're safe and reliable.
So, in summary, nuclear auxiliary power systems are like little power plants that use nuclear energy to produce electricity for all sorts of different equipment. There are different types of these systems, but they're all designed to be very safe and reliable.
