Report Details Summary of Plant Status - Units 2 and 3 At the time of this inspection, the two units continued to be permanently shut down. The primary focus at the San Onofre Nuclear Generating Station (SONGS) facility during the inspection period was associated with decommissioning planning and security modifications to support the change in plant conditions. The licensee also prepared schedules and developed required submittals associated with future decommissioning activities. The licensee continued to drain fluids from various plant systems and abandon systems no longer required to be operable. All systems needed for the safe storage of spent fuel were appropriately maintained.

1 Self-Assessments, Audits, and Corrective Actions (40801)

1.1 Inspection Scope The inspector conducted document reviews and interviews with plant personnel to assess the licensees performance as it related to the following areas:

• Administrative procedures prescribed actions for the identification, evaluation, and resolution of problems;

• Licensee procedures prescribed thresholds for the performance of self-assessments, audits, and surveillances;

• Licensee management reviewed self-assessments, audits, and corrective actions to remain knowledgeable of plant performance; and

• Issues or problems were identified and corrected in accordance with the licensees corrective action program (CAP) through a sampling of select issues.

The inspector reviewed CAP documents on a weekly basis to determine: if a sufficiently low threshold for problem identification existed; the quality of follow-up evaluations including extent of condition; and if the licensee assigned timely and appropriate prioritization for issue resolution commensurate with the significance of the issue.

Issues that were repetitive and those with the potential for safety or regulatory consequence were evaluated further to assess apparent and/or common cause and significance.

1.2 Observations and Findings The inspector determined that issues were identified by the licensee at an appropriate threshold within various functional areas of the site and entered into the CAP. Issues were effectively screened, prioritized, and evaluated commensurate with safety significance. The scope and depth of evaluations were adequate in that the evaluations reviewed addressed the significance of issues and assigned appropriate corrective actions.

2 Decommissioning Performance and Status Review (71801)

2.1 Inspection Scope The inspector evaluated whether the licensee was conducting decommissioning activities in accordance with license and regulatory requirements. The inspector conducted document reviews, observations, and interviews with plant personnel to assess the licensees performance as it related to the following areas:

• Status of decommissioning through the observation of licensee meetings that planned, reviewed, assessed, and scheduled the conduct of facility decommissioning;

• Whether licensee activities were in accordance with license conditions and docketed commitments;

• Operability and functionality of systems necessary for safe decommissioning was assessed through control room and plant walkdowns including the following systems:

radioactive effluent monitoring, spent fuel pool cooling, level and temperature control, radiation protection monitors and alarms, equipment important to emergency preparedness, and equipment that provided normal and standby electrical power;

• Operator logs and data taking for normal facility operations, surveillances, maintenance and verification that data out of specification was appropriately dispositioned and resolved;

• Assessed ongoing in-plant work activities to ensure work activities were evaluated for risk in accordance with 10 CFR 50.65(a)(4), operational work risk assessments were performed and operations shift turnovers appropriately communicated pertinent plant status;

• Verified appropriate plant staffing was maintained and that appropriate management oversight of licensee and supplemental activities were performed;

• Verified pre-job briefs were conducted for facility operations including maintenance, surveillance, operations, and decommissioning activities;

• Verified that system isolations, boundaries and abandonment plans for saltwater cooling, emergency core cooling, component cooling water, and electrical distribution systems ensured proper control of systems important to safe shutdown and did not adversely affect the overall plant configuration;

• Performed frequent plant tours to assess field conditions and decommissioning abandonment activities;
