Nuclear Regulatory Commission to hold meeting in Carlsbad on decommissioning of San Onofre

CARLSBAD, Calif. - A public meeting on the decommissioning of the San Onofre Nuclear Generating Station in northern San Diego County will be held by the Nuclear Regulatory Commission in Carlsbad Thursday night.

The 6 p.m. hearing at the Omni La Costa Resort and Spa will delve into issues brought about by the decision of Southern California Edison – the plant's operator and majority-owner -- to shutter the two reactors.

The NRC's technical staff is scheduled to deliver a 45-minute presentation on the decommissioning process and regulations and will then take questions from the public.

Troubles at the plant, which delivered 20 percent of its power to San Diego Gas & Electric, began in January 2012 when a small, non-injury leak was discovered in one of the two reactors. The other unit was shut down for maintenance at the time.

A subsequent investigation by Edison revealed excessive wearing of pressure tubes caused by vibrations in massive steam generators manufactured by Mitsubishi Heavy Industries of Japan and installed in 2010 and 2011.

The NRC on Monday cited Edison for the failure. The utility is taking legal action against Mitsubishi.

Rosemead-based SCE announced in early June that it would retire both reactors after a plan to restart the unit where no leak occurred ran into opposition.

 

According to the NRC, the doors to the hearing room will open at 5 p.m. to allow for security screening. The hotel is located at 2100 Costa del Mar Road.
