Uranium 235 Plutonium
Uranium 235 or Plutonium 239
Uranium. Most current power reactors use Uranium enriched to 3% Uranium-235.
I think you mean Uranium /U/.
Presuming you mean fuel that is burned, coal, oil and gas come from underground mines and wells. Some experimental or small scale stations burn rubbish or biomass such as elephant grass grown for the purpose. Nuclear stations don't burn anything, but their raw material is often called fuel. This is often uranium, which is also mined.
Uranium is enriched in the isotope uranium-235, producing uranium-238 as waste.
all mass was created in the big bang It is often found near or around volcanoes. The element of sulphur was created during nuclear fusion in a star like our Sun.
As often as they need to.
No, Uranium is a rare-ish element whose radioactive isotope is often used in nuclear reactors. ingestion of radioactive elements can result in death
Synthetic elements are those elements that are not naturally occurring on earth, but rather have been synthesized in a nuclear reactor. They are often radioactive with short halflifes.
Power turbines are driven by steam. Steam can be raised by thermal, nuclear or geothermal processes. Wind and water can also drive a generator. The auxiliaries for a power station (which I think is what this question is asking) are typically powered by step down transformers within the power station. In nuclear power stations there are often standby-critical supplies which are driven by gas turbines or diesel generators.
