SUBJECT:

NORTH ANNA POWER STATION - NRC INTEGRATED INSPECTION REPORT 05000338/2008004 AND 05000339/2008004

Dear Mr. Christian:

On September 30, 2008, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your North Anna Power Station Units 1 and 2. The enclosed integrated inspection report documents the inspection findings which were discussed on October 15, 2008, with Mr.

Larry Lane and other members of your staff.

The inspection examined activities conducted under your licenses as they related to safety and compliance with the Commissions 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, one NRC-identified finding of very low safety significance (Green) was identified. This was determined to involve a violation of NRC requirements. However, because of its very low safety significance and because it was entered into your corrective action program, the NRC is treating this finding as a non-cited violation (NCV) consistent with Section VI.A.1 of the NRC Enforcement Policy. If you wish to contest this non-cited violation, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington DC 20555-001; 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 North Anna Power Station.

VEPCO

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter, its enclosure, and your response, if any, will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the 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).

SUMMARY OF FINDINGS

IR 05000338/2008-004, 05000339/2008-004; 07/01/2008 - 09/30/2008; North Anna Power

Station, Units 1 and 2; Routine Integrated Report, Other Activities.

The report covered a 3-month period of inspection by resident inspectors and two announced inspections by regional reactor inspectors. One finding was identified and determined to be an NCV. The significance of most findings is identified by their color (Green, White, Yellow,

Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process Revision 4, dated December 2006.

NRC Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

Green.

The inspectors identified a non-cited violation of 10 CFR 50.9 for failure to provide complete and accurate information for one licensed operator on the initial license application. The facility licensee submitted a NRC Form-396 (Certification of Medical Examination by Facility Licensee) without identifying a pre-existing medical condition. The facility licensee took prompt corrective actions, which included removing the operator from license duties and submitted an NRC Form-396 requesting to have the operators license amended with the appropriate restriction. The NRC imposed a no-solo restriction on the operators license after performing a medical review of supplemental information.

Because this issue affected the NRCs ability to perform its regulatory function, it was evaluated using the traditional enforcement process. This finding is of very low safety significance because there was no evidence that the operator endangered plant operations as a result of performing licensed duties since the original issuance of his license. However, the regulatory significance was important because the incorrect information was provided under sworn statement to the NRC and impacted a licensing decision for the individual. This issue is documented in the facility licensees corrective action program as Condition Report (CR) 090083. (Section 4OA5.3)

Licensee Identified Violations

None

4OA5 Other Activities

.1 (Closed) URI 05000339/2007009-01: Lack of Procedural Guidance During Spurious

Safety Injection and Procedure Usage Flexibility Acceptability As described in Unresolved Item (URI)05000339/2007009-01, NRC inspectors identified an issue related to the adequacy of procedures, and the amount of flexibility allowed in using these procedures, for responding to a spurious Safety Injection.

Upon further review, the NRC has determined that the licensees procedures, and the

guidance for using these procedures, were adequate. This determination was made

after a review of the licensees applicable Emergency Operating Procedures (EOPs),

Westinghouse Owner Group guidelines governing the content and use of these

EOPs, the licensees response to a Westinghouse recommendation to review these

EOPs with respect to an inadvertent safety injection, and the licensees administrative

procedures governing the use of EOPs. Based on these reviews, the inspectors

determined that the URI is not a performance deficiency. This URI is closed.

.2 (Closed) URI 05000339/2007009-02: Lack of an Effective Program to Detect and

Correct Degradations in Unit 2 SSPS Cards

As described in URI 05000339/2007009-02, NRC inspectors identified an issue for the lack of an effective program to detect and correct degradations in the Unit 2 SSPS logic cards.

Upon extensive review by NRC headquarters and regional inspectors, it was determined that there was no violation of NRC Requirements. However, this issue met the threshold for generic communication to the industry in the form of an Information Notice. Based on the evaluation of the event and review of immediate and long term corrective actions, the inspectors determined that the unresolved item could be closed. This URI is closed.

.3 (Closed) URI 0500338, 339/2008002-02, Failure to Report Accurate Medical

Information on Initial Licensing Application

a. Inspection Scope

In NRC Integrated Inspection Report 05000338, 339/2008002 the inspectors identified a URI for the licensee failure to report accurate medical information on an initial licensing application in 2006. The issue was unresolved pending additional guidance from NRC medical review of information provided by the licensee. The inspectors and the NRC medical contractor conducted a review of the additional information provided by the licensee.

b. Findings

Introduction.

The inspectors identified a Green (Severity Level IV) NCV of 10 CFR 50.9 for failure to provide complete and accurate information for one licensed operator on his initial license application.

Description.

The NRCs requirements related to the conduct and documentation of medical examinations for operators are contained in Subpart C, Medical Requirements, of 10 CFR Part 55, Operators Licenses. Specifically, Section 55.21, Medical examination, requires every operator to be examined by a physician when he or she first applies for a license. The physician must determine whether the operator meets the requirements of section 55.33(a)(1), i.e., the operators medical condition and general health will not adversely affect the performance of assigned operator duties or cause operational errors that endanger public health and safety.

Every time an operator applies for a license pursuant to Section 55.31, How to apply, or Section 55.57, Renewal of licenses, an authorized representative of the facility licensee must complete and sign NRC Form-396, Certification of Medical Examination by Facility Licensee, attesting, pursuant to Section 55.23, Certification, that a physician has conducted the required medical examination and determined that the operators medical condition and general health meet the requirements of Section 55.33(a)(1). The facility licensee must also certify which industry standard (i.e., the 1983 or 1996 version of ANSI/ANS-3.4, Medical Certification and Monitoring of Personnel Requiring Operator Licenses for Nuclear Power Plants, or other NRC approved methods) was used in making the fitness determination.

The ANSI standards describe a number of specific operator health requirements and disqualifying conditions. If an operators health does not meet the minimum standards, the facility licensee must request a conditional license in accordance with Section 55.23(b) by submitting the appropriate medical evidence with NRC Form-396.

Pursuant to Section 55.33, Disposition of an initial application, and Section 55.57, as applicable, the Commission will review the license application based on the facility licensees certification and include any conditions in the license that might be necessary based on the supporting medical evidence.

While reviewing medical records, the inspectors discovered that an individual, who was issued an operator license in 2006, had a pre-existing medical condition since 1999 that had not been reported on their original license application. The information submitted would have allowed the NRC to evaluate/disposition the operators initial application as required by 10 CFR 55.33, Disposition of an initial application.

Analysis.

The inspectors determined that the licensees failure to provide complete and accurate information to the NRC, which resulted in an incorrect licensing action, is a performance deficiency because the licensee is expected to comply with 10 CFR 50.9 and it was within the licensees ability to foresee and prevent. Because a violation of 10 CFR 50.9 is considered to be a violation that can potentially impede or impact the regulatory process, the violation was dispositioned using the traditional enforcement process. The finding was more than minor because information was provided to the NRC signed under oath by the Site Vice President and erroneously impacted an NRC licensing decision. There was no evidence that the operator endangered plant operations as a result of the pre-existing medical condition while performing licensed duties since the original license was issued on July 24, 2006.

Inspectors determined that this issue did not meet the criteria for assignment of a cross-cutting aspect.

Enforcement.

10 CFR 50.9 states, in part, Information provided to the Commission by an applicant for a license or by a licensee or information required by statute or by the Commissions regulations, orders, or license conditions to be maintained by the applicant or the licensee shall be complete and accurate in all material respects. 10 CFR 55.23 requires that an authorized representative of the facility licensee shall certify the medical fitness of an applicant by completing and signing a NRC Form-396. NRC Form-396, when signed by an authorized representative of the facility licensee, certifies that a physician conducted a medical examination of the applicant as required in 10 CFR 55.21, and the guidance contained in ANSI/ANS 3.4-1983 was followed in conducting the examination and making the determination of medical qualification.

Contrary to this, on May 5, 2006, a senior licensee representative submitted NRC Form-396 for one individual applying for a reactor operator license that certified that the applicant met the medical requirements of ANSI/ANS 3.4-1983 and that the applicant would not require any restrictions to his license. In fact, the applicant had a pre-existing medical condition which required a no-solo restriction on the operators license in order to meet the medical standards. This information was material to the NRC because the NRC relied on this certification to determine whether the applicant met the requirements to operate the controls of a nuclear power plant pursuant to 10 CFR Part 55. The finding is not suitable for SDP evaluation, but has been reviewed by NRC management and is determined to be a green finding of very low safety significance. Because the failure to provide the information requesting appropriate restrictions on the operators license was of very low safety significance and has been entered into the corrective action program under CR090083, this violation is being treated as a Severity Level IV NCV consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000338, 339/2008004-01, Failure to Provide Complete and Accurate Medical Information to the NRC Which Impacted a Licensing Decision.

The licensee took prompt corrective actions and removed the individual from licensed duties. The licensee entered this issue into their corrective action program under CR090083.
