The proponents of nuclear don't understand that it isn't a silver bullet

It isn't a bullet at all, it is just the best solution that is currently available.

Also, I do like the fact that rather than comparing different power sources you instead decided to nitpick on reasons why nuclear isn't perfect. I didn't say it was perfect, I said:

they are out to make a perfect utopia at any cost, and will accept nothing short of that.

You are kind off proving me right...

finite resource which could power the world for at most 200 years

We have had powered human flight for about 1 century. Our airplanes seem to have improved a bit in this time...

200 years of millions of people not dying from coal power and switching to something better in a century or two sounds really freaking good to me. Also we haven't done exploration for uranium resources for a long time because we are aware of easily accessible locations that are enough for 200 years... with improved technologies we would also be able to access locations which aren't easily accessible. So we most certainly would be able to keep nuclear going for more than 200 years.

How exactly is saving our planet now with the means at our disposal and later switching to something even better, a demerit?

perpetuates commodity based fuel sources that lead to wars

You do realize that rare earth metals needed for pretty much all modern technologies, including your computer, solar panels etc... 'perpetuates commodity based resources that lead to wars'?

Again, not a perfect world. We can either save the world now or wait for a perfect utopia while half the world drowns... or invades inland to escape the rising oceans.

massive fresh water consumption for cooling

Pressurized water reactors keep the boiler water separate from the reactor, which allows this water to be kept free of radioactivity.

Also nuclear plants can be used in conjunction with desalination plants, which would give us more fresh water than we have now.

large up-front investment

But much lower long term costs...

long construction time

Ok, this one is true, which is why we should start building them as soon as possible so they are finished faster, not prevent them from being built at all, which is what opponents like yourself are calling for.

Nuclear plants also work longer than others.

By the way, what does this have to do with:

brings along many of the issues with fossil fuels. Namely:

Because I thought this list would be about that, yet you went off on a tangent.

centralized power generation leads to increased distribution losses

And yet it provides much more power to people than wind and solar at the same monetary price... and a lower price in terms of lives lost.
