I agree that it's a problem. The latter, obviously. Either option is better than endangering 50,000 lives with a nuclear accident. No option is perfect. The noise is incessant, and the scenery is destroyed.
Nukes are pretty ugly too.
Evacuation sirens are plenty noisy. Many residents do not like the asthetics of them. They are also very maintenance-intensive, much more so than other forms of energy. Poor windmill maintenance is bad, but poor nuke maintenance can be a calamity. Even less so.
