==Dear Mr. Gatlin:==
==Dear Mr. Gatlin:==
On March 31, 2011, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Virgil C. Summer Nuclear Station. The enclosed inspection report documents the inspection results, which were discussed on April 12, 2011, with you and other members of your staff. The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel. Based on the results of this inspection, no findings of significance were identified. However, one licensee-identified violation which was determined to be of very low safety significance (Green) is listed in this report. Because of the very low safety significance and because it was entered into your corrective action program, the NRC is treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2 of the NRC's Enforcement Policy. If you contest the NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the United States Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001, with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Virgil C. Summer Nuclear Station.

The inspectors evaluated two equipment issues described in the CRs listed below to verify the licensee's effectiveness with the corresponding preventive or corrective maintenance associated with structures, systems, and components (SSCs). The inspectors reviewed Maintenance Rule (MR) implementation to verify that component and equipment failures were identified, entered, and scoped within the MR program. Selected SSCs were reviewed to verify proper categorization and classification in accordance with 10 CFR 50.65. The inspectors examined the licensee's 10 CFR 50.65(a)(1) corrective action plans to determine if the licensee was identifying issues related to the MR at an appropriate threshold and that corrective actions were established and effective. The inspectors' review also evaluated if maintenance preventable functional failures (MPFFs) or other MR findings existed that the licensee had not identified. The inspectors reviewed the licensee's controlling procedures, i.e., engineering services procedure (ES)-514, Rev. 5, "Maintenance Rule Implementation," and station administrative procedure (SAP)-0157, Rev. 0A, "Maintenance Rule Program," to verify consistency with the MR requirements.

The inspectors conducted more in-depth reviews of the two issues listed below to evaluate the effectiveness of the licensee's corrective actions for important safety issues. 1) Operating Experience Smart Sample (OpESS) FY 2010-01, "Recent Inspection Experience for Components Installed Beyond Vendor Recommended Service Life" The inspectors performed searches of the licensee's corrective action database for the previous 5 years to identify aging concerns that were similar to those listed in OpESS FY 2010-01. From the results of this search, inspectors selected CR-08-01513 and performed an in-depth review of the associated corrective actions, with a focus on procedures for establishing shelf life criteria and preventive maintenance for components. CR-08-01513 discussed a past Part 21 detailing the life expectancy of electrolytic capacitors found in several Woodward diesel generator components, evaluated the impact on installed Woodward components, and listed several necessary corrective actions. The inspectors assessed whether the issue was properly identified; documented accurately and completely; adequately considered extent of condition; and identified appropriate and timely corrective actions. Inspectors also selected four sets each containing a Woodward 2301a governor and a DRU (Digital Reference Unit), examining the applicable procurement procedures, purchase orders, refurbishment documentation and shelf life criteria. Documents reviewed by the inspectors included:

The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section 2.3.2 of the NRC Enforcement Policy, for being dispositioned as an NCV.
The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section 2.3.2 of the NRC Enforcement Policy, for being dispositioned as an NCV.
* 10CFR 55.25 states "If, during the term of the license, the licensee develops a permanent physical or mental condition that causes the licensee to fail to meet the requirements of § 55.21 of this part, the facility licensee shall notify the Commission, within 30 days of learning of the diagnosis, in accordance with § 50.74(c). For conditions for which a conditional license (as described in §55.33(b) of this part) is requested, the facility licensee shall provide medical certification on Form NRC 396 to the Commission (as described in § 55.23 of this part)."  Contrary to this, the licensee identified that they did not notify the Commission within 30 days after a licensed operator was diagnosed with a permanent physical medical condition as required by 10 CFR 55.25. This was identified in the licensee's CAP as CR 11-00304 and 11-00031. This finding was of very low safety significance because the licensed operator performs non-licensed shift technical advisor duties and has been inactive during the time in question.

.2 Annual Sample Review

a. Inspection Scope

The inspectors conducted more in-depth reviews of the two issues listed below to evaluate the effectiveness of the licensee's corrective actions for important safety issues. 1) Operating Experience Smart Sample (OpESS) FY 2010-01, "Recent Inspection Experience for Components Installed Beyond Vendor Recommended Service Life" The inspectors performed searches of the licensee's corrective action database for the previous 5 years to identify aging concerns that were similar to those listed in OpESS FY 2010-01. From the results of this search, inspectors selected CR-08-01513 and performed an in-depth review of the associated corrective actions, with a focus on procedures for establishing shelf life criteria and preventive maintenance for components.

CR-08-01513 discussed a past Part 21 detailing the life expectancy of electrolytic capacitors found in several Woodward diesel generator components, evaluated the impact on installed Woodward components, and listed several necessary corrective actions. The inspectors assessed whether the issue was properly identified; documented accurately and completely; adequately considered extent of condition; and identified appropriate and timely corrective actions. Inspectors also selected four sets each containing a Woodward 2301a governor and a DRU (Digital Reference Unit), examining the applicable procurement procedures, purchase orders, refurbishment documentation and shelf life criteria. Documents reviewed by the inspectors included:

  • CR-08-01513, Evaluate age of capacitors for Woodward Governor electronic controls
  • CR-08-03760, OE26873, Evaluate DG erratic KW output event at Cooper Nuclear Station for applicability to VC Summer

b. Findings

No findings were identified.

4OA5 Other Activities

Quarterly Resident Inspector Observations of Security Personnel and Activities

a. Inspection Scope

During the inspection period, the inspectors conducted observations of security force personnel and activities to ensure that the activities were consistent with licensee security procedures and regulatory requirements relating to nuclear plant security.

These observations took place during both normal and off-normal plant working hours.

These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status review and inspection activities.

b. Findings

No findings were identified.

4OA6 Meetings, Including Exit

Quarterly Resident Inspector Exit Meeting On April 12, 2011, the resident inspectors presented the integrated inspection results to Mr. Thomas Gatlin and other members of the licensee staff. The licensee acknowledged the results of these inspections. The inspectors confirmed that inspection activities discussed in this report did not contain proprietary material.

4OA7 Licensee-Identified Violations

The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section 2.3.2 of the NRC Enforcement Policy, for being dispositioned as an NCV.

  • 10CFR 55.25 states "If, during the term of the license, the licensee develops a permanent physical or mental condition that causes the licensee to fail to meet the requirements of § 55.21 of this part, the facility licensee shall notify the Commission, within 30 days of learning of the diagnosis, in accordance with § 50.74(c). For conditions for which a conditional license (as described in §55.33(b) of this part) is requested, the facility licensee shall provide medical certification on Form NRC 396 to the Commission (as described in § 55.23 of this part)." Contrary to this, the licensee identified that they did not notify the Commission within 30 days after a licensed operator was diagnosed with a permanent physical medical condition as required by 10 CFR 55.25. This was identified in the licensee's CAP as CR 11-00304 and 11-00031. This finding was of very low safety significance because the licensed operator performs non-licensed shift technical advisor duties and has been inactive during the time in question.
