- EDWIN I. HATCH NUCLEAR PLANT -
DOCKET NOS. 50-321 AND 50-366
Dear Mr. Madison:
This refers to the meeting conducted on September 29, 2010, in Vidalia, GA. The purpose of the Regulatory Performance Meeting was to provide opportunities to discuss the corrective actions associated with the two White findings that were documented in NRC Inspection Reports (05000321,366/2009008, and 05000366/2010006) regarding Edwin I. Hatch Nuclear Plant with the public. The findings dealt with failure of the 1B emergency diesel generator coupling and failure to establish appropriate preventative maintenance for electrolytic capacitors.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be available electronically for public inspection in the NRC Public Document Room (PDR) or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS).
ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Should you have any questions concerning this meeting, please contact me at (404) 997-4521.
Sincerely,
/RA/

Licensee discussion of corrective actions
95002 Supplemental Inspection INSPECTION FOR ONE DEGRADED CORNERSTONE OR ANY THREE WHITE INPUTS IN A STRATEGIC PERFORMANCE AREA Provide assurance that the causes of individual and collective performance issues are understood NRC independently assess the extent of condition and the extent of cause of individual and collective performance issues NRC independently determine if safety culture components caused or contributed to the individual and collective performance issues Provide assurance that a licensees corrective actions for significant performance issues are sufficient to address the causes and prevent recurrence
95002 Supplemental Inspection INSPECTION FOR ONE DEGRADED CORNERSTONE OR ANY THREE WHITE INPUTS IN A STRATEGIC PERFORMANCE AREA
- The 95002 was completed the week of August 23, 2010
- The inspection reviewed the following White Findings:
- Failure to establish preventative maintenance (PM) to replace electrolytic capacitors
95002 Supplemental Inspection INSPECTION FOR ONE DEGRADED CORNERSTONE OR ANY THREE WHITE INPUTS IN A STRATEGIC PERFORMANCE AREA
- The NRC inspection team determined that the following inspection objectives were satisfied:
- Assurance that the root and contributing causes were understood
- Assurance that the corrective actions for the performance issues were sufficient to address the root and contributing causes and prevent recurrence
95002 Inspection Results INSPECTION FOR ONE DEGRADED CORNERSTONE OR ANY THREE WHITE INPUTS IN A STRATEGIC PERFORMANCE AREA
- The NRC inspection team performed actions to independently:
- Assess the extent of condition and the extent of cause of the issues.
- Determine if safety culture components caused or significantly contributed to the identified issues.
95002 Inspection Results INSPECTION FOR ONE DEGRADED CORNERSTONE OR ANY THREE WHITE INPUTS IN A STRATEGIC PERFORMANCE AREA
- Conclusions
- Licensees corrective actions included the following:
- Revised their PM Implementation and their Continuing Equipment Reliability Improvement plans as follows:
- Clear definition of Service Life (based on vendor recommendations, qualification testing, OE, etc).
- Guidance for including service life and relevant OE in PM templates
- Clarifying roles and responsibilities
- Condition reports initiated for exceeding service life
95002 Inspection Results INSPECTION FOR ONE DEGRADED CORNERSTONE OR ANY THREE WHITE INPUTS IN A STRATEGIC PERFORMANCE AREA
- Conclusions Contd
- Licensee adequately addressed commonality between the two findings:
- Use of vendor recommendations and operator experience (OE)
- Evaluation of service life and establishment of timely repetitive tasks for replacement of components prior to failures
- No findings were identified
Overall Assessment Impact Overall, Hatch Unit 1 performance has remained in the Licensee Response Column for CY 2010 to date.
Overall, Hatch Unit 2 performance was determined to be in the Degraded Cornerstone of the NRCs Action Matrix; however, given a successful 95002 inspection and no additional inputs, Unit 2 is projected to return to the Licensee Response Column during the 4th Qtr 2010.

NRC Findings Hatch failed to perform Preventive Maintenance on some safety related components that have a specific service life:
- 1. Components containing electrolytic capacitors and some types of relays
- 2. Diesel Generator couplings Causes Design program was not focused on future preventive maintenance.
Missed opportunities to identify & resolve service life issues.
Actions Taken
- Added resources, focused on fixing the causes.
- Determined what other equipment should have an established service life.
- Determined that equipment was performing as expected.
- Established a schedule & priorities to change out all affected components
- Fixed the Design process to ensure it focuses on future preventive maintenance.
- Improved the Corrective Action Program requirements.
- Training for the staff.
