Investigation: Radioactive leaks at Illinois nuclear plants

From Madison.com, November 17, 2018.

Radioactive waste continues to pour from Exelon’s Illinois nuclear power plants more than a decade after the discovery of chronic leaks led to national outrage, a $1.2 million government settlement and a company vow to guard against future accidents, an investigation by a government watchdog group found.

Since 2007, there have been at least 35 reported leaks, spills or other accidental releases in Illinois of water contaminated with radioactive tritium, a byproduct of nuclear power production and a carcinogen at high levels, a Better Government Association review of federal and state records shows.

No fines were issued for the accidents, all of which were self-reported by the company.

The most recent leak of 35,000 gallons (132,000 liters) occurred over two weeks in May and June at Exelon’s Braidwood plant, southwest of Chicago. The same facility was the focus of a community panic in the mid-2000s after a series of accidents stirred debate over the safety of aging nuclear plants.

A 2014 incident at Exelon’s Dresden facility in Grundy County involved the release of about 500,000 gallons (1,900,000 liters) of highly radioactive water. Contamination was later found in the plant’s sewer lines and miles away in the Morris, Illinois, sewage treatment plant.
