Records Show 56 Safety Violations at U.S. Nuclear Power Plants in Past 4 Years
Mishandled Radioactive Material and Failing Backup Generators Among the Violations

()...Among the litany of violations at U.S. nuclear power plants are missing or mishandled nuclear material, inadequate emergency plans, faulty backup power generators, corroded cooling pipes and even marijuana use inside a nuclear plant, according to an ABC News review of four years of Nuclear Regulatory Commission safety records.
(... )And perhaps most troubling of all, critics say, the commission has failed to correct the violations in a timely fashion.
"The Nuclear Regulatory Commission has very good safety regulations but they have very bad enforcement of those regulations," said David Lochbaum, a nuclear scientist with the nonprofit Union of Concerned Scientists.
There are 104 U.S. nuclear power plants.
Lochbaum and the Union of Concerned Scientists found 14 "near misses" at nuclear plants in 2010. And there were 56 serious violations at nuclear power plants from 2007 to 2011, according the ABC News review of NRC records.
At the Dresden Nuclear Power Plant in Illinois, for instance, which is located within 50 miles of the 7 million people who live in and around Chicago, nuclear material went missing in 2007. The Nuclear Regulatory Commission fined the operator -- Exelon Corp. -- after discovering the facility had failed to "keep complete records showing the inventory [and] disposal of all special nuclear material in its possession."
As a result, two fuel pellets and equipment with nuclear material could not be accounted for.
Two years later, federal regulators cited Dresden for allowing unlicensed operators to work with radioactive control rods. The workers allowed three control rods to be moved out of the core. When alarms went off, workers initially ignored them.
"This event is disturbing," Lochbaum of the Union of Concerned Scientists said. "In August 1997, the NRC issued information … about a reactivity mismanagement problem at Exelon's Zion nuclear plant," which was retired the following year.
"It was an epoch event in the industry in that other plants owners noted it and took steps to address [the issue]. Yet, a decade later, Exelon's Dresden plant experiences an eerily similar repetition of the control-room operator problems."
