Nuclear Power Plants: Ranking America's Most Vulnerable

The Daily Beast rates the vulnerability of all 65 U.S. nuclear facilities based on safety records, potential disasters and nearby populations.

After the crisis at Japan's Fukushima nuclear plant, the safety of domestic nuclear reactors is under serious scrutiny. Nuclear Regulatory Commission chairman Gregory Jaczko reassured Congress earlier this week that American nuclear reactors can survive major natural disasters, but some critics argue that U.S. reactors may be even more vulnerable than the ones in Japan. Nuclear reactors are engineered to withstand certain levels of disaster, based on projections beyond what the area has experienced. But should an unprecedented disaster take place, as with Japan, it's impossible to definitively establish whether the operating reactors in the U.S. would remain safe.

According to Biff Bradley, the director of risk assessment for the Nuclear Energy Institute, it's almost impossible to try to rank the absolute safety risk of a plant, due to the number of variables that would be involved in any sort of direct comparison. But given that some fundamental risks are obvious and plant safety records are public, relative risks can be measured. For instance, nearly half of the 104 nuclear reactors operating in the United States are close to major fault lines, including the Diablo Canyon and San Onofre plants located near California's San Andreas Fault. The Indian Point nuclear power plant in New York is less than two miles from the Pampano fault line, and sits within 50 miles of more than 17 million people.

Based on the input of more than a half-dozen experts in nuclear energy, nuclear engineering and risk assessment, The Daily Beast ranked the country's power plant sites based on three, equally weighted metrics: risk of natural disaster, safety performance assessments, and surrounding population. In other words, which nuclear power plants are located in the most dangerous physical locations, have the weakest relative operating conditions, and would affect the greatest number of people should an unforeseeable emergency occur?
