Severe storms and tornadoes moving through the U.S. Southeast dealt a severe blow to the Tennessee Valley Authority [on April 27], causing three nuclear reactors in Alabama to shut and knocking out 11 high-voltage power lines, the utility and regulators said. All three units at TVA's 3,274-megawatt Browns Ferry nuclear plant in Alabama tripped about 5:30 EDT after losing outside power to the plant, a spokesman for the U.S. Nuclear Regulatory Commission said. A TVA spokeswoman said the station's backup power systems, including diesel generators, started and operated as designed. External power was restored quickly to the plant but diesel generators remained running Wednesday evening, she said. The Browns Ferry units are among 23 U.S. reactors that are similar in design to the crippled Fukushima Daiichi nuclear plant in Japan where backup generators were swept away in the tsunami that followed the massive earthquake on March 11.

Note: And what might have happened if one of those tornadoes happened to hit a nuclear power plant?
