VERMONT YANKEE NUCLEAR POWER STATION - NRC INTEGRATED INSPECTION REPORT 05000271/2004006
Dear Mr. Thayer:
On December 31, 2004, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Vermont Yankee Nuclear Power Station (VY). The enclosed report documents the inspection findings which were discussed on January 6, 2005, with Mr. W. Maguire and other members of your staff.
The inspection examined activities conducted under your license as they relate 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, the NRC has determined that a Severity Level IV violation of NRC requirements occurred. This violation is being treated as a Non-Cited Violation (NCV), consistent with Section VI.A of the Enforcement Policy. The NCV is described in the inspection report. If you 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 U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555-0001 with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, U.S.
Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the NRC Resident Inspector at the Vermont Yankee Nuclear Power Station.
In accordance with 10 CFR 2.390 of the NRC's "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

Clifford J. Anderson, Chief Projects Branch 5 Division of Reactor Projects Docket No. 50-271 License No. DPR-28 Enclosure: Inspection Report 05000271/2004006 w/Attachment: Supplemental Information
Mr. Jay
SUMMARY OF FINDINGS
IR 05000271/2004006; 10/01/04 - 12/31/04; Vermont Yankee Nuclear Power Station; Other
Activities.
This report covered a 13-week period of inspection by resident inspectors and announced inspections by a regional senior operations engineer, senior reactor engineer, reactor engineer, and a senior health physicist. One Severity Level IV non-cited violation (NCV) was identified.
The significance of most findings is indicated 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 NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 3, dated July 2000.
NRC-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
Severity Level IV. The inspectors identified a Severity Level IV NCV of 10 CFR 50.74(c) because Entergy did not notify the NRC within 30 days of the identification of a medical condition that caused a licensed senior operator to fail to meet the requirements of 10 CFR 55.21. That medical condition ultimately required the NRC to issue a conditional [restricted] license. Specifically, Entergy became aware of a medical condition in March 2004 that caused a licensed senior operator to fail to meet the requirements of 10 CFR 55.21 and for which a conditional [restricted] license was required. However, Entergy did not notify the NRC of the medical condition until five months later, in August 2004.
Entergys failure to report the medical condition to the NRC impacted the regulatory process, in that, between April and August 2004, the NRC was unaware of a medical condition that warranted issuance of a conditional [restricted] license. Because the finding impacted the regulatory process, it was dispositioned using the traditional enforcement process instead of the significance determination process. This issue has been entered into Entergys corrective actions program. (Section 4OA5)
B. Licensee Identified Findings None.

REPORT DETAILS
Summary of Plant Status
Vermont Yankee Nuclear Power Station began the inspection period with the reactor at full power operation and with the exception of minor power reductions for control rod pattern adjustments, continued at, or near, full power for the remainder of the inspection period.
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity
1R01 Adverse Weather Protection
1. Readiness for Seasonal Susceptibilities
a. Inspection Scope
(two samples)
The inspectors reviewed measures established by Entergy for cold weather operations.
The inspectors reviewed Vermont Yankee Operating Procedure (OP) 2196, Preparations for Cold Weather Operations, and its Forms 1, Cold Weather Operations Checklist, and 4, Operations Cold Weather Protection Verification Checklist, and discussed the completion of items with operations personnel to confirm the items on the checklists were either completed or appropriately tracked for completion. The inspectors walked down the intake structure, condensate storage tank, and emergency diesel generator rooms to independently verify that selected actions to prepare for cold weather operations were completed appropriately and systems were kept at temperatures to ensure operability. The inspectors also reviewed recent condition reports (CRs) related to cold weather protection to ensure proper actions were taken in response to identified issues.
Additionally, the inspectors reviewed measures established by Entergy for minimizing the impact of a tornado on the continued availability of the emergency diesel generators (EDGs). The inspectors reviewed the Individual Plant Examination of External Events (IPEEE), the Updated Final Safety Analysis Report (UFSAR), and the Vermont Yankee Topical Design Basis Document (DBD) for External Events to ensure all tornado-related vulnerabilities had been identified and appropriately addressed including the installation and maintenance of tornado vent dampers for each EDG room. The inspectors also reviewed Engineering Design Change Request (EDCR)97-407, Installation of Emergency Diesel Generator Room Tornado Dampers and NRC Information Notice 96-06, Design and Testing Deficiencies of Tornado Dampers at Nuclear Power Plants.
The inspectors performed walkdowns of the EDG rooms and tornado dampers to ensure dampers were unobstructed and to observe general physical condition. Additionally, the inspectors reviewed CRs related to the EDG tornado dampers to ensure identified problems were properly resolved (a listing of CRs reviewed is included in the attachment to this report).
b. Findings
The EDG rooms have dampers (louvers) installed to provide a pressure relief path to prevent the EDG room walls from collapsing during a design basis tornado event.
During the inspectors review of the preventive maintenance (PM) performed on the tornado dampers the inspectors determined that the dampers are inspected, lubricated, and manually cycled open and closed every 18 months.
Although the PM applied to the dampers provides evidence that the dampers will open manually, the inspectors questioned whether manually cycling the dampers open and closed is a sufficient test to demonstrate that the dampers open within the design basis differential pressure range (0.28 to 0.35 pounds per square inch (psid)) specified in EDCR 97-407. 10 CFR 50, Appendix B, Criterion XI, Test Control, requires, in part, that testing be performed on safety-related components to demonstrate that the component will perform satisfactorily in service and that this testing be performed in accordance with written procedures that incorporate the requirements and acceptance limits contained in the applicable design documents.
In response to the inspectors questions, Entergy entered the issue into its corrective action program (CR 2004-3293). Also, Entergy developed an operability determination which demonstrated that the EDG room tornado dampers are currently able to perform their design function if called upon.
Entergy Engineering Department personnel plan to perform an engineering analysis of the current PM performed on the EDG room tornado dampers to determine if manually cycling the dampers opened and closed is a sufficient test to assure that the dampers will open within the design basis differential pressure range. Entergy is also developing an enhanced testing methodology for the EDG tornado dampers. Following completion of Entergys engineering analysis, the inspectors can determine whether the testing performed under the PM meets the requirement of 10 CFR 50, Appendix B, Criterion XI, Test Control. As a result, this issue is considered to be an unresolved item (URI):
URI 05000271/2004006-01, Adequacy of Testing for Emergency Diesel Generator Room Tornado Dampers .
1R04 Equipment Alignment
1. Complete Equipment Alignment (71111.04S)
a. Inspection Scope

The inspectors performed a complete equipment alignment inspection of the accessible portions of the high pressure coolant injection (HPCI) system. The inspectors walked down the HPCI system and compared actual equipment alignment to approved piping and instrumentation diagrams, operating procedure lineups, the Vermont Yankee UFSAR, and the Vermont Yankee design basis document (DBD). The inspectors observed valve positions, the availability of power supplies, and the general condition of selected components to verify there were no unidentified deficiencies. The inspectors also confirmed that licensee-identified equipment problems had been entered into the corrective actions program.
b. Findings
No findings of significance were identified.
2. Partial Equipment Alignments (71111.04)
a. Inspection Scope
(three samples)
The inspectors performed three partial system walkdowns of risk significant systems to verify system alignment and to identify any discrepancies that would impact system operability. Observed plant conditions were compared with the standby alignment of equipment specified in Entergys system operating procedures and drawings. The inspectors also observed valve positions, the availability of power supplies, and the general condition of selected components to verify there were no obvious deficiencies.
The inspectors verified the alignment of the following systems:
- The B train of the residual heat removal service water (RHRSW) system during planned maintenance on the A train of the RHRSW system,
- The B train of the residual heat removal (RHR) system during planned maintenance on the A train of the RHR system, and

The inspectors performed a walkdown of portions of the SW, RHRSW, and alternate cooling systems, including the intake and discharge structures and cooling tower CT 2-1 to assess the condition of these components. The inspectors reviewed the frequency of maintenance and cleaning of heat exchangers with the system engineer to ensure that these activities were scheduled and performed using trend data developed from periodic heat transfer tests and previously performed visual inspections. The inspector examined the trending of the measured data for the service water system components. The inspectors reviewed the methods and results of heat exchanger performance inspections and cleaning to ensure that the methods used were consistent with the expected degradation. The inspectors reviewed the disposition of as-found results to ensure that the as-left conditions were acceptable. The inspectors reviewed the history of system piping corrosion and discussed the macro-fouling and corrosion experience with the system engineer and discussed the limitations imposed on chemical treatment of the service water and residual heat removal service water systems.
b. Findings
No findings of significance were identified.
1R11 Licensed Operator Requalification Program
1. Quarterly Requalification Review (71111.11Q)
a. Inspection Scope
(one sample)
The inspectors observed a simulator session for one operating crew to assess the performance of the licensed operators and the ability of Entergys Training Department staff to evaluate licensed operator performance. Operating crew performance was evaluated during a scenario which involved the loss of a direct current (DC) electrical bus, recirculating pump trip and an unisolated steam leak in secondary containment.
The inspectors evaluated the crews performance in the areas of:
- Clarity and formality of communications;
- Ability to take timely actions;
- Prioritization, interpretation, and verification of alarms;
- Procedure use;
- Control board manipulations;
- Oversight and direction from supervisors; and
- Group dynamics.
Crew performance in these areas was compared to Entergy management expectations and guidelines as presented in the following documents:
- Vermont Yankee Administrative Procedure (AP) 0151, Responsibilities and Authorities of Operations Department Personnel;
- AP 0153, Operations Department Communication and Log Maintenance; and
- Vermont Yankee DP- 0166, Operations Department Standards.
The inspectors also compared simulator configurations with actual control board configurations. For any weaknesses identified, the inspectors observed the evaluators to verify that they also noted the issues and discussed them with the crew.
b. Findings
No findings of significance were identified.
2. Biennial Operator Requalification Review (71111.11B)
a. Inspection Scope
(one sample)
The inspectors reviewed documentation of operating history since the last requalification program inspection. The inspectors also discussed facility operating events with the resident staff. Documents reviewed included NRC inspection reports and 10 condition reports to ensure that operational events were not indicative of possible training deficiencies.
The inspectors verified that documented Requalification Training Schedule changes were made to address specific events. A sample of ten training records were reviewed to verify completion of this training.
The inspectors reviewed five senior reactor operator (SRO) and five reactor operator (RO) comprehensive biennial written exams administered in November 2003. In addition, the inspectors reviewed three sets of Scenarios and job performance measures (JPMs) administered during this current exam cycle to ensure the quality of these exams met or exceeded the criteria established in NUREG 1021, Operator Licensing Examination Standards for Power Reactors, and 10 CFR 55.59. The inspectors observed the administration of operating examinations to one operating crew.
The operating examination consisted of two simulator scenarios and one set of five JPMs administered to each individual.
For the VY plant referenced simulator, the inspectors observed simulator performance during the conduct of the examinations and reviewed simulator performance tests (e.g.,
steady state performance tests, selected transient tests, selected scenario based tests, normal plant evolution tests, and core performance tests) and simulator deficiency reports to verify compliance with the requirements of 10 CFR 55.46. A listing of tests and data reviewed is included in the Attachment to this report.
The inspectors reviewed an Entergy self-assessment conducted in the 2nd quarter of 2004 regarding the simulator testing program.
Conformance with operator license conditions was verified by reviewing the following records:
- Attendance records for the most recent year training cycle;
- Six medical records (three SRO and three RO) and to verify that all records were complete, that restrictions noted by the doctor were reflected on the individuals license and that the exams were given within 24 months;
- Proficiency watch-standing and reactivation records. A sample of five licensed operator watch-standing documentation was reviewed for the current and prior quarter to verify currency and conformance with the requirements of 10 CFR 55;
- Remediation training records for the prior two years.
In regard to Entergys feedback system, the inspectors interviewed instructors, training/operations management personnel, and licensed operators for feedback regarding the implementation of the licensed operator requalification program to ensure the requalification program was meeting their needs and was responsive to their noted deficiencies/recommended changes. In addition, recent modifications to the feedwater and reactor recirculation system were reviewed to ensure that they were adequately addressed in the Requalification Training Program.
The inspectors conducted an in-office review of Entergys requalification exam results.
These results included the annual operating test only (i.e., the comprehensive written exam was administered and reviewed by NRC staff last year). The inspection assessed whether pass rates were consistent with the guidance of NRC Manual Chapter 0609, Appendix I, Operator Requalification Human Performance Significance Determination Process . The inspectors assessed the following areas:
- Crew failure rate on the dynamic simulator was less than 20 percent,
- Individual failure rate on the dynamic simulator test was less than or equal to 20 percent,
- Individual failure rate on the walk-through test was less than or equal to 20 percent,
- Individual failure rate on the comprehensive biennial written exam was less than or equal to 20 percent, and
- More than 75 percent of the individuals passed all portions of the exam.

4OA5 Other Activities
1. (Closed) Unresolved Item (URI)05000271/2004005-01, Issues Identified with the
Evaluation and Reporting of Changes in Licensed Senior Operator Medical Condition.
a. Inspection Scope
The inspectors evaluated actions taken by Entergy to evaluate the medical condition of a licensed senior reactor operator who developed a medical condition that was reportable. The inspectors reviewed the licensed senior operators medical records, American National Standards Institute (ANSI) American National Standard (ANS)-3.4-1983, American National Standard Medical Certification and Monitoring of Personnel Requiring Operator Licenses for Nuclear Power Plants; 10 CFR 50.74, Notification of Change in Operator or Senior Operator Status; 10 CFR 55.21, Medical Examinations; 10 CFR 55.23, Certification; 10 CFR 55.25, Incapacitation Because of Disability or Illness; and Entergy Nuclear Northeast Organization and Management Procedure ENN-OM-117, Medical Program Procedure. Additionally, the inspectors reviewed the reportability aspects of the licensed senior operators medical condition as delineated in 10 CFR 50.74(c) and 10 CFR 55.25. The inspectors interviewed Operations Department personnel including the licensed senior operator with the medical condition.
b. Findings
Introduction:
The inspectors identified a Severity Level IV NCV of 10 CFR 50.74(c)because Entergy did not notify the NRC within 30 days of the identification of a medical condition that caused a licensed senior operator to fail to meet the requirements of 10 CFR 55.21. That medical condition ultimately required the NRC to issue a conditional
[restricted] license.
Description:
On January 12, 2004, a licensed senior reactor operator developed a medical condition that required the operator to recuperate away from work until March 2004. The inspectors review of the licensed senior operators medical records in June 2004 identified that Operations Department Management had cleared the individual to return to licensed duties in March 2004 without the Entergy Medical Examiner (i.e., the doctor responsible for the medical evaluations of licensed operators) reviewing the medical condition as required by Entergys medical program procedure.
Once prompted by the inspectors, the Entergy Medical Examiner reviewed the medical condition and on June 14, 2004, determined that the medical condition caused the operator to fail to meet the requirements of 10 CFR 55.21 and recommended that the operators license include a no solo medical restriction (i.e., would require another qualified individual to be present while performing licensed duties). This recommendation was provided to the facility medical files administrator. On July 1, 2004, the inspectors identified that the medical files administrator had not forwarded the Entergy Medical Examiners medical restriction recommendation to the operator, to Operations Department Management, or to the NRC as required by Entergys medical program procedure.
On August 5, 2004, Entergy notified the NRC via an NRC Form 396, Certification of Medical Examination by Facility Licensee, of the medical condition that caused the operator to fail to meet the requirements of 10 CFR 55.21 and recommended that the operators license include a no solo medical restriction. Based on the information provided on the NRC Form 396, the NRC issued a conditional [restricted] license on November 8, 2004.
The inspectors determined that the operator had not performed licensed duties since returning to work in March 2004 and that the issue had been entered into Entergys Corrective Actions Program as CRs 2004-2158, 2004-2218, and 2004-2229.
Analysis:
The performance deficiency associated with this finding is that Entergy did not notify the NRC within 30 days of the identification of a medical condition that caused a licensed senior reactor operator to fail to meet the requirements of 10 CFR 55.21 as required by 10 CFR 50.74(c). The NRC relies on facility licensees to evaluate medical conditions and, if warranted, to report those changes to the NRC so that the NRC can take appropriate regulatory action including issuance of a conditional [restricted] license.
The inspectors determined that Entergys failure to report the medical condition to the NRC impacted the regulatory process, in that, between April and August, 2004, the NRC was unaware of a medical condition that warranted issuance of a conditional [restricted]
license. Because the finding impacted the regulatory process, it was dispositioned using the traditional enforcement process instead of the SDP.
Enforcement:
10 CFR 50.74(c) requires, in part, that each facility licensee notify the NRC within 30 days of a permanent disability or illness as described in 10 CFR 55.25 in regards to a licensed operator or senior operator. 10 CFR 55.25 requires, in part, that if a licensed senior operator develops a permanent physical or mental condition that causes the licensed senior operator to fail to meet the requirements of 10 CFR 55.21, the facility licensee must notify the NRC within 30 days of learning of the diagnosis. For conditions for which a conditional [restricted] license is required, the facility licensee must provide medical certification on NRC Form 396, Certification of Medical Examination by Facility Licensee. Contrary to the above, Entergy did not notify the NRC within 30 days of learning of a medical condition of a licensed senior operator for which a conditional [restricted] license was required. Specifically, Entergy became aware of a medical condition on March 2004 that caused a licensed senior operator to fail to meet the requirements of 10 CFR 55.21 and for which a conditional [restricted]
license was required. Entergy did not provide the NRC Form 396 medical certification to the NRC until August 5, 2004.
Entergys failure to notify the NRC of the licensed senior operators medical condition is considered a violation of 10 CFR 50.74(c). The violation is determined to be a Severity Level IV (Supplement 1) violation. Additionally, the licensed senior operator had not been assigned or performed licensed duties since returning from medical leave in March 2004. Because the violation is a Severity Level IV and has been entered into Entergys corrective action program, this violation is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000271/2004006-02, Entergy Did Not Notify the NRC of a Licensed Senior Operators Medical Condition.
