Yes, very much so. 104 reactors working in the US alone and about 400 world wide
Controlled! ...if the reactor is working properly.
You would not be able to obtain the fissile material necessary to build a working model of a nuclear power plant. You could build a model, for sure, but it would not be a working model.
There are no nuclear power plants in Australia. There is one small working nuclear reactor at the Lucas Heights research facility in Sydney.
As of end of August 2013, there are 434 working nuclear power reactors (with total rated power 370.543 Gigawatt plus 69 nuclear power reactors under construction (with total rated power 67.196 Giagawatt).
Yes
A nuclear power plant is safe if it's designed on the most advanced safety measures. Its accurate and permanent maintenance issues are essential to keep any nuclear power plant working safely. I think visitors are not allowed in Nuclear Power Plants.
Governments want scientists to work on a nuclear power plant to lessen the dependence of fossil fuels. The product of nuclear power plants are atomic energy, a clean energy alternative.
Iran's first nuclear power plant, Bushehr I, is expected to be operational in 2009. There are no current plans to complete the Bushehr II reactor, although the construction of 19 nuclear power plants is envisaged. Iran has announced that it is working on a new 360 MWe nuclear power plant to be located in Darkhoyen.
There can be potential health risks associated with working at a nuclear power station, such as radiation exposure. Workers must adhere to strict safety protocols and procedures to minimize these risks. Additionally, the nature of the job may involve working in high-pressure environments or dealing with hazardous materials, so physical and mental health considerations are important.

Nuclear fission is the working principle under which the nuclear reactors operate.
