I think that Nuclear power plants are poorly represented in Civ. 1. They do not melt down that often. Some countries use nuclear power quite effectively and very safely. But in civ, I seem to get a meltdown every five years or so. 2. Even if they do meld down, it isn't like an atom bomb going off! When Chernobyl melted down, it didn't kill half the population of Ukraine! I think that it would be better just to make a nuclear power plant cost more due to its increased productivity, vise the all to frequent melt down.
