Power levels are the percent of licensed thermal power that each plant reported to the Nuclear Regulatory Commission for the morning of each day. Zero percent usually means the reactor is shut down for refueling or maintenance. This is not a safety rating. For emergencies near a plant, follow your local emergency management agency.
