Using nuclear installations requires the most adroit skills and protective "armor" for workers.

That is why it is important to maintain a skills level in being around such edifices containing nuclear objects.

For, it is likely that nuclear reactions will be part of creating electricity for storage in batteries as a practical source of energy, but in contradistinction to the carbon based energy sources.  As another source, perhaps rising to become the primary source of energy, it will be processed and stored as an electrical power source--it is hoped. 

So, with the promise of nuclear power becoming a major source in creating electricity, it is important to keep current in the methods of handling objects that are used in creating nuclear reactions.

My opinion.
