Here we have a completely opposite situation compared to the previous entry. Connecticut offers good wage and promises job opportunities. There will be 20 more nuclear engineers employed in the future compared to current 840. There are some other positive things like biggest per capita income in the nation and highest human development index. However, it is also the state with the highest cost of living index on our list of best states for nuclear engineers. Connecticut had two nuclear power plants, but one was decommissioned in 2004.
