5 billion years
A star becomes a white dwarf when it exhausts its nuclear fuel and can no longer produce energy through fusion reactions. Gravity causes the core to collapse while the outer layers are expelled into space, leaving behind a dense, Earth-sized remnant known as a white dwarf.
No, the sun is not eternal. It is estimated to have a lifespan of about 10 billion years, with roughly 5 billion years remaining until it exhausts its nuclear fuel and turns into a red giant before ultimately fading away.
The sun is currently considered to be in the middle of its life cycle. It is about 4.6 billion years old and is expected to shine for another 5 billion years before it exhausts its nuclear fuel and undergoes significant changes.
A star shines due to nuclear fusion in its core, where hydrogen atoms combine to form helium, releasing energy in the process. This energy radiates outwards, providing the star with heat and light. This process can last for billions of years until the star exhausts its nuclear fuel.
The sun shines due to nuclear fusion in its core, where hydrogen nuclei fuse to form helium. This process provides the sun with the energy needed to shine, and it is estimated that the sun will continue to shine for another 5 billion years before it exhausts its hydrogen fuel and transitions to the next stage of its life cycle.
The used fuel in a nuclear power plant is the nuclear fuel being discharged from the nuclear reactor after being irradiated during reactor operation. It is usually composed of trans-uranium heavy elements, a wide variety of fission products (that resulted from the nuclear fission processes in the nuclear reactor) and products of radioactive decay (produced before and after fuel discharge from the nuclear reactor).
This takes around 6.000.000 years but it could take longer depending on the amount of nuclear fuel spilt.
Nuclear fuel remains dangerously radioactive for thousands of years after it is no longer useful in a commercial reactor.

When a star exhausts its nuclear fuel and can no longer undergo fusion, it will undergo significant changes depending on its mass. A low to medium-mass star, like the Sun, will expand into a red giant and eventually shed its outer layers, forming a planetary nebula, while the core will collapse into a white dwarf. More massive stars will explode in a supernova, leaving behind a neutron star or a black hole, depending on their remaining mass.

Plutonium can no longer be used as a source of energy in nuclear reactors due to its high rate of radioactive decay, which makes it less effective as a fuel. Additionally, the use of plutonium raises safety concerns and proliferation risks, leading to a shift towards alternative nuclear fuel sources.
my studys have shown it will explode in about 12.5 years. sincerly, Dr. Brown of the university of sun studys

As far as distance, nuclear powered submarines can go around the world four times on their nuclear fuel. As far as "before they need re-supply", I don't know but I am guessing it is a minimum of 40-60 days, maybe longer.
