An important exposé by Jeff Donn of the Associated Press on June 21 that shows that "radioactive tritium has leaked from three-quarters of U.S. commercial nuclear power sites, often into groundwater from corroded, buried piping." The story confirms the findings in our 2010 report, Leak First, Fix Later. Beyond Nuclear also contributed background on the story. Some leaks migrated off site and at three sites — two in Illinois and one in Minnesota — leaks have contaminated drinking wells of nearby homes, the AP report shows. Read the full AP investigation.
Appendix A of the Beyond Nuclear report "Leak First, Fix Later" lists the radioactive leak events at each of the US nuclear power plants through April 2010.
