Southern California Edison (SCE) has received a final Special Inspection Report from the Nuclear Regulatory Commission noting a “Greater than Green” classification for a SCE self-reported finding from 2011 at the San Onofre Nuclear Generating Station.
As the original June 11, 2012 commission Special Inspection Report noted, the deficiency was promptly corrected and addressed in 2011, before the commission inspectors arrived on site.
The finding is described in the commission report as “failure to develop a site procedure which addressed the need to conduct a cyber-security analysis of electronic devices designated for Safeguards Information (SGI) use.” SGI is information that is related to the overall security of the plant and has restricted access.
The commission evaluated this finding during a four-day security baseline inspection at the San Onofre Nuclear Generating Station on May 16, and is now classifying it as a “Greater than Green” finding, which means it is of more than very low security significance and may require additional commission inspections. Because of the rigorous nature of nuclear safety and security regulation, all findings are treated seriously. SCE did not contest the finding.
“The San Onofre Nuclear Generating Station management and employees are committed to safety, security and regulatory compliance,” said Senior Vice President and Chief Nuclear Officer Pete Dietrich. “We corrected this deficiency last year when we discovered it and have implemented best practices for information security to ensure it doesn’t happen again.”
Details on the specifics of the finding are not available due to security regulations that are established by the commission and federal law.
