On May 28th there was a chlorine leak at the Oyster Creek Nuclear Power Plant and luckily there were no injuries. See: http://www.app.com/story/news/local/southern-ocean-county/lacey/2014/05/28/oyster-creek-chlorine-leak/9676877/
The US nuclear power industry has one of the best safety records in the world with strict oversight, strong industry initiatives to continuously improve safety and performance, and an excellent track record in safety. However, even in the well-run plants, there is always the possibility of undetected problems and human failure to adhere to procedures. For this reason, the use of potentially hazardous materials such as chlorine need to be carefully considered. Not only are there hazards at the plants, there are hazards to the public from transport and use of chlorine. An article in Environmental Health News, “Special report: Chlorine accidents rupture life for workers, townspeople”, notes that the US Department of Transportation and the US Department of Labor’s Occupational Safety and Health Administration have documented the high risks of chlorine. See http://www.environmentalhealthnews.org/ehs/news/2011/chlorine-accidents/.
We can do better! Much safer alternatives to chlorine exist for power plants.
