A great comment by John Morgan on BNC answers the question:
Q. Is nuclear power evil?
A. For many greens, opposition to nuclear power is automatic. Nuclear power stands for war, sickness, invisible radiation, toxic waste, an apocalyptic symbol of technology gone awry.
The idea of nuclear energy as a kind of modern day evil is an indulgence we can no longer afford. It is not some mysterious malignancy. It is a mature, safe, unremarkable technology that provides carbon free electricity for many communities. The real consequences of climate change beginning around us are set to become far worse than the imagined perils of nuclear power.
It is time to set aside the mythology and theatre of anti nuclear sentiment. Nuclear power is still a core environmental issue today, but this time around, we support it as strongly as it was once opposed.
