They are not going good here.

Only roughly 30% of nuclear plants are working. It is because of extremely long downtime for overhaulling. I heared 50% of their lifetime will be spent for overhauling and repairing.

They are not absolutely different from unlimited energy source. I doubt they are economically efficienct as well.

At least very stable as long as working.

The oldest plants are now being scrapped. All the workload will require 50 years to be scrapped safe and clean according to the plant's report. This happened in the United States and Russia, and is happening in Japan, and will soon happen all the countries that possess nuclear plants.

I hope renewable energy can be prominent choices for stable energy sources soon. And geothermal will be a choice in the near future if it happens.
