Safety Breaches Seen Plaguing U.S. Reactors in Report

Almost one-in-six U.S. nuclear reactors experienced safety breaches last year due in part to poor oversight by federal regulators, according to the Union of Concerned Scientists.

Incidents including a cooling water leak and unusual wear on steam generator tubes were reported at 16 units owned by companies including Entergy Corp. and Edison International, the Cambridge, Massachusetts-based environmental group said in its third annual report on reactor safety released today.
