There is a bad stigma associated with nuclear energy that I just don’t understand - Nuclear less impact to the environment when compared to other energy sources. What is is the problem with nuclear? Is it the cost of maintaining these power plants ?

I went back and forth a few times with my opinion on nuclear over the years and some points I've gathered, good and bad are:

-Nuclear is indeed a low-carbon energy source.

-It's also what you would want as baseload.

-The costs of storing waste properly have been underestimated - a few years ago nuclear operators reached a deal with the German government through which they paid 23bln Euros to make the waste the government's problem. The overall sentiment is that they were let off the hook easily and the total cost will be much higher.

-Both nuclear plants and waste storage facilities are easy targets for terrorism - fortunately that didn't happen yet, but things like Stuxnet proved that it's entirely in the realm of possibility. My pet conspiracy theory is that this, not Fukushima was the reason Germany eventually accelerated its plans to phase out nuclear.

-You can reprocess spent nuclear fuel which helps both with fuel accessibility and waste management.

-It's trivially easy to use the reprocessing infrastructure to create weapons-grade plutonium.

-Nuclear is generally safe.

-That being said its mode of failure makes a large area inhospitable essentially forever. Topsoil radiation measurements usually don't give the full picture of the problem.

-Every nuclear disaster resulted in increased safety by uncovering design flaws which were a result of cutting corners, so especially in the decade after Fukushima costs went up around 24% making nuclear the single low-carbon source to become more, not less expensive.

-As it stands even China cannot deploy nuclear fast enough to compete with renewables on delivered MWh. Since 2012 wind consistently delivered more energy in China than nuclear and the gap has been widening ever since. With the cost of storage plummeting we're heading towards a future where centralised power generation may become antiquated.

----

Overall nuclear has some advantages but there aren't enough of them to break the trend of using renewables + gas and storage, which on average replace coal faster and cheaper.

It's basically a textbook example of "worse is better".

I don't agree with you and most experts don't either. Storage is a solved problem. Nuclear is a solved probem. Energy storage on the scale of 1 week+ in cases of blizzards, and other freak weather events which are only going to get worse over the next century is not viable. Nuclear is here and it's safe and it's dependable and it might be the only way to save our planet (or at least us humans, the planet would do just fine without us).

Doesn't change the fact that nuclear capacity is currently not growing nearly as fast as renewables.

Because of non-scientific ideologues. If all the pro-nuke people sabotaged solar rollouts would you say that solar was less viable, or would you blame the sabotage?

Nuclear is also quite expensive.

Who has been sabotaging nuclear reactors?

GreenPeace, for example, has been lying about nuclear power forever. All the radiation grifters on Youtube who talk about scintillations per m^3 of seawater as proof that Fukushima is killing Californians, etc.

"Concerned citizens" who demand endless studies about things we already have a good understanding of.

People who ignore the 10,000 deaths per week worldwide because of coal power but focus on the ~2 deaths from Fukushima.

Right, smear. Sabotaging the process.

Oh, smear campaigns. I though you mean people were sabotaging reactors.
