Caption: San Onofre Nuclear Generating Station
The U.S. Nuclear Regulatory Commission (NRC) said it is dropping its investigation of Southern California Edison and the shut down San Onofre Nuclear Generating Station (SONGS) in California.
The dual-unit plant shut down in January 2012 for a scheduled outage when workers discovered premature wear in tubes inside the four steam generators that had been replaced during a major overhaul three years prior. SCE said in August 2013 that it would permanently shut down the plant instead of performing costly repairs.
The NRC ruled that SCE did not recognize design flaws in the generators that led to several issues. The NRC said in several letters to petitioner Friends of the Earth that suspending SCE’s operating licenses are a moot point because the utility cannot load fuel or run the steam generators since it announced the shut down.
