I may be biased by living in San Diego, but the "civilian" oversight of nuclear energy has failed. We have a nuclear power plant here 60 miles from downtown which is bogged down in endless hearings and oversight. Taking the safety issues seriously is great, but it's obvious the government teams lack the expertise and will to actually help get the reactor running again or decide to shut it down permanently.
Meanwhile there are 3+ perfectly fine nuclear reactors running on aircraft carriers and subs docked right at downtown San Diego all the time. No one seems to mind and no one seems to worry.
Whether that's justified or not doesn't really matter. The Navy can and does build new nuclear power plants and generally has the trust of the public to do that. The DOE does not. These are the results: the military has effective nuclear power, the civilians do not.
