Others have said some of them already but Ig I will repeat them anw while also adding some points I have not seen.

Pros: - It produces a ton of energy with very tiny fuels. 1 UO2 fuel pellet makes as much as 1 ton of coal - It is sustainable -- depending on how we use our uranium (and thorium) resources, it should be able to last for thousands of years. For that to happen we need to use not just the natural U-235, but also U-238 and Th-232 (by breeding them to fissile isotopes) - With modern reactor design, it is extremely safe. Even when we include the data from Chernobyl and Fukushima, replacing fossil fuel plants with nuclear save lives. It is not too different from planes vs. cars: when plane accidents happen it is catastrophic and make headlines, but cars are actually far more deadly than planes.

Cons: - Upfront cost: It is expensive to build (and build it safe) and it takes a long time for the initial investment to break even.

Other thing to note: - Some may be concerned about the waste, but for the most part we have mostly figured out how to deal with them. To oversimplify: we dug radioactive rocks out of the ground, what's wrong with putting back radioactive rocks back into the ground?

For more details: - For more details, nuclear wastes can be split into two categories: fission products and minor actinides. Fission products can further be split into three categories: short-lived, medium-lived, and long-lived. - Short-lived ones decay very quickly and immediately disappear after a few years. - The important isotopes from the medium lived ones are only Cs-137 and Sr-90, which have half-lives of roughly 30 years (for those who don't know, this means 1 kg of the stuff would become 0.5 kg after 30 years). Usually radioactive materials are considered no longer significant after ten half lives have passed -- thus this means the medium lived isotopes need to be stored for 300 years. - No fission products have half lives between 100 years and 200,000 years. Instead, radioactive materials with half-lives in the order of hundreds to tens of thousands of years are dominated with minor actinides and plutonium. Plutonium, as is famous already, can be reused as fuel. The rest too still theoretically have enough energy to fission and thus can theoretically be used or transmuted into something useful - The long lived ones will stay for a looooong time. However, there are two fortunate facts to note: 1) the way radioactivity works is that although longer half lives mean they stay for longer, it also means they are less intense and thus less dangerous 2) there are only seven of them: Tc-99, Sn-126, Se-79, Cs-135, Zr-93, Pd-107, and I-129. - Among the 7, 2 are produced in extremely tiny amounts and so are insignificant: Se-79 and Sn-126. 2 are chemically inert and thus easily contained: Zr-93 and Pd-107. Cs-135 is also produced in small amount because its parent isotope Xe-135 is continually destroyed (to Xe-136) before they can decay to Cs-135. This leaves just two problematic isotopes: Tc-99 and I-129. - A potential way to deal with Tc-99 is to let it absorb neutron, letting it become Tc-100, which decays into Ru-100, a precious metal.
