Attachment II to WM 10-0024 Page 1 of 1 Corrective Actions Being Taken to Address the Four Examples Specified in PI&R, Corrective Action Crosscutting Theme In addition to the actions being taken to address the new crosscutting theme in Corrective Actions, WCNOC is taking corrective actions to address the following four examples identified in the reference. These actions have been documented and are being tracked in the Corrective Action Program. This list is not all inclusive.

1. A failure to establish goals and monitor the offgas radiation monitoring systems per 10 CFR 50.65 (effectiveness of maintenance).

Response: Engineering updated the scoping functions to identify specifically when the failure was a functional failure or unavailability time only. Unavailability events were reviewed and updated appropriately. Maintenance Rule lesson plans were revised to reflect expectations and responsibilities. Maintenance Rule training will be presented to appropriate engineering support incumbents. Maintenance Rule training is scheduled for completion on December 16, 2010. Reference Condition Report (CR) 24423.

2. The failure to correct an inadequate reactor vessel vent path during an outage.

Response: A corrective action plan has been created to correct the reactor head vent path. The reactor head vent plan implementation is scheduled for completion May 31, 2011. Reference CR 22501.

3. The failure to have adequate acceptance criteria for the effects of essential service water (ESW) system corrosion.

Response: The lake water systems procedures will be revised to include acceptance criteria to mitigate and manage deficiencies on an overall system basis. The due date is October 21, 2010. Reference CR 22243.

4. The use of a non-safety related power supply in a safety related system.

Response: Preventive maintenance, on a 3-month basis, was established to measure the alternating current ripple voltage at the direct current input to the annunciator power supply to the emergency diesel generators (EDG). Work requests will be written if the established limit is exceeded. The annunciator power supply will be replaced in the plant annunciator system, and in the EDGs, through configuration change package 13312. The scheduled completion date is March 24, 2011. Safety related filtering capacitors will be added to the EDGs, adjacent to the power supplies, to protect the speed switch from a failed power supply. The EDG "B" capacitor was replaced August 26, 2010 and EDG "A" capacitor replacement is scheduled for October 4, 2010.
