ZOMG TOXIC WASTE WILL KILL US ALL!!! ok now we have the irrational argument out of the way lets have the rational one. Nuclear power emits far less carbon per Kwh then fossil fuel by a considerable margin, they also produce far less of other pollutants !@#$%^&*ociated with fossil fuel. They are many times more safe than the ones that have gone through melt down in the past, odds of it occuring are too low to be of significance in a modern system. The waste can be safely contained, and the cost of doing so is justified by the fact that it is still cheaper then fossil fuel, and the price of the power generation is less likely to spike like it does with oil. security and fail safes are such that they will not make a viable terrorist target. Renewables cant be used to get rid of nuclear entirely as large scale power stations are needed to input a base level into the grid to meet minimum requirement, renewable can provide a lot of energy but the output is too variable to rely on completely. for instance no wind means your wind turbines arent working, and clouds reduce output from solar arrays.
