Te growing Threat of Extreme Weathert to Nuclear Facilities

Nuclear power plants worldwide have historically been designed for a baseline set of environmental conditions, but those baselines are shifting. Hurricanes wigh higher wind speeds, storm surges that baseline set of environmental conditions, and heatwaves that push coloing water temperatures beyond coxn limits are meing thee new normal.

For example, the 2011 Fukushima Daiichi disaster was triggered by a tsunami that submitmed seawalls andd backup power systems, leading to core meltdows.
