France must resort to importing electricity during a severe cold snap because 9 of its 58 reactors are shut down for various reasons. This calls into question nuclear power industry claims of being a reliable source of baseload electricity, and further shatters the myth that nuclear power in France operates without a hitch. As the Union of Concerned Scientists reported in its 2006 "Walking a Nuclear Tightrope: Unlearned Lessons of Year-plus Reactor Outages," nuclear power's un-reliability has plagued the U.S. time and time again. In a destabilized climate, such atomic outages will only increase as a safety precaution.
