4 of the 10 oldest U.S. reactors are located on the Great Lakes shore (as are Canada's 4 oldest reactors)In a photo essay focused on the ten oldest operating atomic reactors in the United States, National Geographic reports on findings by Nuclear Regulatory Commission inspectors revealing weaknesses to seismic and fire risks post-Fukushima. Not mentioned is the fact that four of the ten oldest reactors -- Nine Mile Point Unit 1, NY; R.E. Ginna, NY; Point Beach Unit 1, WI; and Palisades, MI -- are located on the shoreline of the Great Lakes, 20% of the world's surface fresh water, drinking water supply for 40 million people downstream in the U.S., Canada, and numerous Native American First Nations. Four more of the ten oldest U.S. reactors -- Dresden Units 2 and 3, IL; Monticello, MN; and Quad Cities Unit 1, IL -- are located just outside, or not very far from, the Great Lakes watershed, in terms of the potential for airborne fallout from a catastrophic radioactivity release, as clearly shown by the widespread contamination downwind and downstream of the Fukushima Daiichi nuclear catastrophe. (Not mentioned in the article is the fact that four of Canada's oldest reactors -- four units at Pickering A nuclear power plant just east of Toronto -- also are located on Lake Ontario's shore.) All 10 atomic reactors mentioned in the National Geographic article have already had 20 year license extensions rubberstamped by the NRC.
