You can bring up the idea of the cold war and the fear of the spread of communist governments. The fear was that if governments that were hostile towards the United States obtained nuclear weapons then we would no longer have the strategic advantage. This fear led to the Cuban Missile Crisis when the Soviet Union supplied Cuba with weaponry that could reach the United States.

Russians do not know how to use nuclear weapons
A looming concern was that neither the long-distance telephone plant, nor the basic military command and control network would survive a nuclear attack.
Nuclear threats are a real cause for concern. It seems that North Korea is making some real headway in their nuclear technology and is getting closer to mounting a nuclear bomb to a missile. This is great cause for concern since North Korea is constantly talking about a nuclear assault on the United States.

concern with international crises and the threat of nuclear war.
A leak of contaminated water.
Concern 1. Nuclear meltdown. If correct maintenance is not observed, the core may overheat and eventually melt. This will cause the escape of radiation. Concern 2. Disposal of contaminated equipment and fuel rods. These are very hazardous and environmentally unsound. Concern 3. The waste products from a nuclear power plant can be used to create weapons of mass destruction, and therefore must be disposed of properly.
