Nuclear UCS Myths and Facts About The Dresden Water Leak Imm Sampling of monitoring wells at Dresden "was discontinued in 1993."
Absolutely Not True. Sampling of wells and other collection points has been continuous at Dresden since the station began operating and has never been stopped or suspended. Sampling of a limited number of wells ended in late 2003, but that involved only a quarter of the 96 wells and sample points in use at the site. Using language such as "reportedly discontinued" and "UCS has been told that... " does not absolve the Union of Concerned Scientists from spreading inaccurate information.
"Had the [June 27, 2004] earthquake not prompted a Absolutely Not True. Dozens of other monitoring wells and look, the leaks may have continued undetected for many locations around the site are monitored on a continuous schedule years."
and would have picked up any leakage during 2004. The well where the leak was detected was sampled at the end of July as part of routine checks following the June 27 earthquake. Had the earthquake not occurred, the leak would have been detected in other scheduled checks over the next several months, probably as early as August.
"The worst news is that Dresden's owners discontinued Absolutely Not True. Again, Dresden has never discontinued a sampling program in 1993 and the NRC allowed them its sampling program, which has received continuous oversight to do it."

Equipment problems compounded the leak Absolutely Not True. Other than the pipe itself, there have been no equipment problems associated with the leak. UCS is referring to valves that were closed on either side of the leak when it was discovered. The valves functioned as designed and helped eliminate 95% of the leak a few days after it was discovered. Almost all of the remaining leakage was collected, treated and recycled into the plant. Any residual tritium water leakage will be eliminated by Oct. 19.
"Consolidated Edison, the former owner of the Dresden Absolutely Not True. Not to pile on in pointing out UCS nuclear station..."
inaccuracies, but Consolidated Edison, a New York utility, never owned Dresden. Dresden was built and operated by Commonwealth Edison of Chicago until 2000, when Exelon was formed.
