The modern, smaller-scale reactors are going to prove quite valuable. Efficient, safe and economical, CO2 free sources of energy are quite welcome additions to our power resources. Nuclear power has been pretty safe for the most part. The USN has a very admirable track record operating quite a few reactors. Newer reactors and possibly the advent of Thorium fueled reactors will give us lots of choices in the near future.

And as soon as Fusion happens, we can all rest easy.
