U.S. Nuclear Agency Hid Concerns, Hailed Safety Record as Fukushima Melted

Fukushima Daiichi Units 1 to 4 were General Electric Mark I Boiling Water Reactors. The U.S. has 23 still-operating Mark Is, as well as an additional 8 Mark IIs of very similar design.

As reported by NBC News's Bill Dedman, the U.S. Nuclear Regulatory Commission's (NRC) Office of Public Affairs defended its own image, as well as that of the nuclear power industry, as its top priority during the first days of the fast-breaking Fukushima Daiichi nuclear catastrophe three years ago. As revealed by internal NRC emails obtained via the Freedom of Information Act (FOIA), NRC went so far as to attack Dedman's own reporting at the time, when he used a little known NRC report published in 2010 to rank the seismic risk at atomic reactors across the U.S. The confusion created by NRC's attack on Dedman's reporting dissuaded other news outlets, including the New York Times, from mentioning NRC's ranking of seismic risks -- of which Entergy Nuclear's twin reactor Indian Point nuclear power plant on the Hudson River near New York City had the worst ranking in the U.S. 21 million people live or work within 50 miles of Indian Point. In 2008, seismologists at Columbia University warned about previously unknown earthquake fault lines near Indian Point.
