Three Mile Island Radiation Leak


Three Mile Island nuclear plantA radiation leak has been reported at the Three Mile Island Nuclear Plant near Harrisburg, Pennsylvania. Yes, despite the meltdown at this plant 30 years ago, portions are still functional today.

Apparently, an Exelon maintenance crew was performing maintenance work in the Unit 1 reactor building when a radiation alarm sounded. Workers were cutting a large number of pipes at the time. Unit 1 has been shut down for several weeks to overhaul new steam generators and other equipment.

Twenty employees were treated for radiation exposure. Original reports indicated over 100 workers needed to be decontaminated.

Exelon does not know the cause, but believes the incident does not pose an occupational threat, nor a threat to public health and safety. The cause of the leak is under investigation by the Nuclear Regulatory Commission and the entire plant is now shut down.

Even if this event really is not a threat to public health, it reveals that radiation dangers from nuclear power still exist, despite efforts to improve safety systems following the 1986 Chernobyl nuclear accident.
