SUBJECT:
VOGTLE ELECTRIC GENERATING PLANT - NRC INTEGRATED INSPECTION REPORT 05000424/2003004 AND 05000425/2003004
Dear Mr. Gasser:
On September 27, 2003, the US Nuclear Regulatory Commission (NRC) completed an inspection at your Vogtle Electric Generating Plant (VEGP), Units 1 and 2. The enclosed integrated inspection report documents the inspection results, which were discussed on October 3, 2003, with Mr. W. Kitchens 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.
This report documents two NRC-identified findings and one self-revealing finding of very low safety significance (Green), all of which were determined to involve violations of NRC requirements. However, because of their very low safety significance and because they were entered into your corrective action program, the NRC is treating these violations as non-cited violations (NCVs) consistent with Section VI.A.1 of the NRC Enforcement Policy. Additionally, licensee-identified violations, which were determined to be of very low safety significance, are listed in Section 4OA7 of this report. If you contest any NCV in this report, 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 Vogtle.
In accordance with 10 CFR 2.790 of the NRCs Rules of Practice, a copy of this letter, its enclosures, 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.html (the Electronic Reading Room).

SUMMARY OF FINDINGS
IR 05000424/2003-004, 05000425/2003-004; 06/29/2003 - 09/27/2003; Vogtle Electric
Generating Plant, Units 1 and 2; Licensed Operator Requalification, Maintenance Risk Assessments and Emergent Work Evaluation, and Refueling and Outage Activities.
The report covered a three-month period of inspection by resident inspectors and announced inspections by regional health physics inspectors and operations engineers. Three Green non-cited violations (NCVs) were identified. The significance of most findings is indicated by their color (Green, White, Yellow, or 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 management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described NUREG-1649, Reactor Oversight Process, Revision 3, dated July 2000.
NRC-Identified and Self-Revealing Findings
Cornerstone: Initiating Events
- Green.
A self-revealing NCV of Technical Specification (TS) 5.4.1.a was identified for failure to maintain a suitable reactor vessel vent path during reduced reactor coolant system (RCS) level conditions in accordance with plant shutdown procedures.
This finding is greater than minor because it affected the configuration control attribute of the Initiating Events Cornerstone objective, in that, the failure to maintain a suitable vent path resulted in inaccurate level indication and a perturbation in actual RCS water level. The finding was determined to be of very low safety significance because all of the equipment, procedures, and policies that are expected to be maintained in the five shutdown safety functional areas were met. The direct cause of this finding involved the cross-cutting area of Human Performance. (Section 1R20)
Cornerstone: Mitigating Systems
- Green.
An NCV of TS 5.4.1.a was identified for the failure of multiple Part 55 licensees to reactivate Reactor Operator (RO) and Senior Reactor Operator (SRO)licenses in accordance with plant administrative procedures.
This finding is greater than minor because it affected the Mitigating Systems Cornerstone objective, in that, it is associated with human performance attributes of license reactivation that affect operational safety. The finding was determined to be of very low safety significance because more than 20 percent of the reactivation records reviewed failed to meet the requirements. The direct cause of this finding involved the cross-cutting area of Human Performance. (Section 1R11)
- Green.
A NCV of 10 CFR 50.65(a)(4) was identified for failure to properly assess and manage the increase in risk of RCS level instrumentation unavailability during a Unit 2 RCS leak repair shutdown outage.
This finding was greater than minor because it affected the configuration control attribute of the Mitigating Systems Cornerstone objective, in that, it involved the availability, reliability, and capability of systems (i.e., RCS level instrumentation) that respond to initiating events (e.g., loss of RCS inventory in reduced level conditions) to prevent undesirable consequences. The finding was determined to be of very low safety significance because all of the equipment, procedures, and policies that are expected to be maintained in the five shutdown safety functional areas were met.
The direct cause of this finding involved the cross-cutting area of Human Performance. (Section 1R13)
Licensee-Identified Violations
Violations of very low safety significance, which were identified by the licensee have been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. These violations and corrective action tracking numbers are listed in Section 4OA7 of this report.
REPORT DETAILS
Summary of Plant Status
Unit 1 operated at essentially full Rated Thermal Power (RTP) until September 27, when a shutdown commenced for a planned refueling outage.

==1R11 Licensed Operator Requalification
a. Inspection Scope
Resident Observations:==
The inspectors observed operator performance during licensed operator simulator training associated with Requalification Segment 20034. The inspectors evaluated operator performance during the conduct of a simulator scenario that began with a steam generator pressure transmitter failure followed by a reactor coolant system temperature channel failure, a main feedwater piping rupture, failure of an automatic safety injection (SI) actuation signal, and ended with the failure of an automatic main steam line isolation actuation signal. The inspectors specifically assessed the following areas:
- Correct use of abnormal and emergency operating procedures including 18001-C, Primary Systems Instrumentation Malfunction; 19000-C, E-0 Reactor Trip or Safety Injection; 19010-C, E-1 Loss of Reactor or Secondary Coolant; 19020-C, E-2 Faulted Steam Generator Isolation; and 19011-C, ES-1.1 SI Termination
- Ability to identify and implement appropriate Technical Specification (TS) actions
- Ability to identify and implement appropriate reporting and emergency plan actions in accordance with procedure 91001-C, Emergency Classification and Implementing Instructions
- Clarity and formality of communications in accordance with procedure 10000-C, Conduct of Operations
- Proper control board manipulations including critical operator actions
- Quality of supervisory command and control
- Effectiveness of the post-evaluation critique Biennial Requalification Program Inspection: The inspectors reviewed documentation, interviewed licensee personnel, and observed the administration of simulator operating tests associated with the licensees operator requalification program to assess the effectiveness of the licensee in implementing requalification requirements identified in 10 CFR 55, Operators Licenses. The evaluations were also performed to determine if the licensee effectively implemented operator requalification guidelines established in NUREG-1021, Operator Licensing Examination Standards for Power Reactors, and Inspection Procedure 71111.11, Licensed Operator Requalification Program. The inspectors also reviewed and evaluated the licensees simulation facility for adequacy for use in operator licensing examinations. The inspectors observed two shift crews and one staff crew during the performance of the operating tests. Documentation reviewed included written examinations, Job Performance Measures (JPMs), simulator scenarios, licensee procedures, on-shift records, licensed operator qualification and reactivation records, watchstanding and medical records, simulator modification request records and performance test records, the feedback process, and remediation plans. Documents reviewed are listed in the Attachment.
Annual Operating Examination Results: On September 25, the licensee completed the comprehensive requalification written examinations and annual operating tests, required to be given to all licensed operators by 10 CFR 55.59(a)(2). The inspectors reviewed the overall pass/fail results of the written examinations, individual operating tests, and the crew simulator operating tests. These results were compared to the thresholds established in Manual Chapter (IMC) 0609, Significance Determination Process (SDP),
Appendix I, Operator Requalification Human Performance SDP.
b. Findings
Introduction.
A Green non-cited violation (NCV) was identified for the failure of multiple Part 55 licensees to reactivate Reactor Operator (RO) and Senior Reactor Operator (SRO) licenses in accordance with procedure 10010-C, Operator Qualification Program, Revision (Rev.) 2.
Description.
10 CFR 55.53(f) required that an operator must stand a minimum of 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> of shift functions under the direction of an operator or senior operator and in the position to which the individual will be assigned. The 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> of reactivation must include a complete tour of the plant. Procedure 10010-C, Section 3.10.2, which implements this requirement, stated that the licensed operator shall perform a comprehensive tour of the plant. As a minimum, the tour of the plant will include a walkdown of all in-plant JPM performance locations on each unit.
The inspectors compared the information contained in eleven reactivation records with vital area computer access records to verify the plant tours were performed as required.
All eleven records showed deficiencies in the area of plant tours. Four of the operators failed to tour more than 50 percent of the JPM performance locations and one operator had less than one minute outside the control building.
Analysis.
This finding is greater than minor because it affected the Mitigating Systems Cornerstone objective, in that, it is associated with human performance attributes of license reactivation that affect operational safety. The finding was evaluated using the Operator Requalification Human Performance SDP (IMC 0609, Appendix I) and determined to be of very low safety significance because more than 20 percent of the reactivation records reviewed failed to meet the requirements. The direct cause of this finding involved the cross-cutting area of Human Performance.
Enforcement.
TS 5.4.1.a requires written procedures be established, implemented and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978, Administrative Procedures. The license requirements given in 10 CFR 55.53(f), Conditions of a Licenses, stated, in part, that the licensee has completed a complete tour of the plant. Data Sheet 2 of procedure 10010-C, Operator Qualification Program, Rev. 2,Section III, stated that the operator must perform a comprehensive tour of the plant including the turbine building, auxiliary building, control building and outside areas. The tour will include a walkdown of all in-plant JPM performance locations on both units. Contrary to the above, the licensee failed to ensure that all Part 55 licensees reactivating met the requirements of procedure 10010-C, Operator Qualification Program, Rev 2. Because the finding is of very low safety significance and has been entered in the licensee corrective action program as CR 2003002132, this violation is being treated as an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000424, 425/2003004-01, Failure to Reactivate Part 55 Licenses in Accordance with Procedure.
==1R13 Maintenance Risk Assessments and Emergent Work Evaluation
a. Inspection Scope
==
The inspectors reviewed the following ten risk significant and emergent maintenance work orders (MWOs) to verify plant risk was properly assessed by the licensee prior to conducting the activities. The inspectors reviewed risk assessments and risk management controls implemented for these activities to verify they were completed in accordance with procedure 00354-C, Maintenance Scheduling, and 10 CFR 50.65(a)(4).
The inspectors also reviewed the CR database to verify that maintenance risk assessment problems were being identified at the appropriate level, entered into the corrective action program, and appropriately resolved.

b. Findings
Introduction.
A Green NCV of 10 CFR 50.65(a)(4) was identified for failure to properly assess and manage the increase in risk of RCS level instrumentation unavailability during a Unit 2 RCS leak repair shutdown outage.
Description.
On August 10, with the unit in cold shutdown, the inspectors reviewed the adequacy of the risk assessment performed to support Unit 2 RCS draindown from 15 percent pressurizer level to one foot below the top of the reactor head. The licensee had calculated the overall plant risk during the evolution to be Low Moderate, (i.e.,
Yellow risk condition) using their Outage Risk Assessment and Management (ORAM)computerized qualitative risk assessment tool. This risk assessment assumed that RCS narrow range level, RCS wide range level, and the RCS sightglass would be available for monitoring vessel water level. Prior to the draindown, the licensee decided not to place the RCS narrow range level in service because vessel water level was not planned to be lowered into the operating range of the instrument. Shortly after reaching the desired level, the RCS wide range instrument was found to be erratic and was not considered reliable for use. Since the RCS narrow range level had not been placed in service, the remaining reliable vessel level indication was from the RCS sightglass.
When the inspectors questioned how the unavailable RCS narrow and wide range level instruments affected the overall plant risk profile, the operators maintained that the plant was still in a Yellow risk condition.
The inspectors discussed the risk assessment with the licensees risk analyst and found that he had not been contacted to discuss the potential impact of the RCS level instrumentation issues on the ORAM risk profile. The inspectors learned that with any one of the three instruments unavailable, ORAM would have reported the overall risk profile as High Moderate and Questionable Risk, (i.e., Orange risk condition).
Therefore, during the period of August 10-11, while either the narrow or wide range level instrument was unavailable, the actual plant risk condition had been Orange versus Yellow. The licensee requires a formal contingency plan to be developed and approved by management for Orange risk conditions. Since the initial risk condition was Yellow, no formal contingency plan had been developed. The inspectors determined that adequate RCS level monitoring capability was still available via the RCS sightglass and Reactor Vessel Level Indication System (RVLIS).
Analysis.
The failure to properly assess risk following changes to planned availability of RCS level instrumentation was greater than minor because it affected the configuration control attribute of the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events (such as a loss of RCS inventory in reduced level conditions). The finding was evaluated using IMC 0609, Appendix G, Shutdown Operations SDP, checklist PWR Cold Shutdown and Refueling Operation RCS Open and Refueling Cavity < 23', and determined to be of very low safety significance because all of the equipment, procedures, and policies that are expected to be maintained in the five shutdown safety functional areas were met.
The direct cause of this finding involved the cross-cutting area of Human Performance.
Enforcement.
10 CFR 50.65(a)(4) requires, in part, that before performing maintenance activities (including, but not limited to surveillances, post-maintenance testing, and corrective and preventive maintenance), the licensee shall assess and manage the increase in risk that may result from proposed maintenance. Contrary to the above, the licensee failed to perform an adequate risk assessment on August 10, 2003, when RCS narrow and wide range level instrumentation was not available during reduced level conditions of a RCS leak repair outage. The failure to perform an adequate risk assessment resulted in the licensee inappropriately assigning an overall Yellow risk condition for Unit 2 when actual plant conditions warranted an Orange risk condition.
Because the finding is of very low safety significance and has been entered into the licensees corrective action program as CR 2003002188, this violation is being treated as a NCV in accordance with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000425/2003004-02, Failure to Assess Increase in Risk of Unavailable RCS Level Instrumentation During Leak Repair Outage.
==1R14 Operator Performance During Non-Routine Plant Evolutions
a. Inspection Scope
==
For the five non-routine plant evolutions described below, the inspectors reviewed the operating crews performance, reviewed operator logs, control board indications, and plant computer data to verify that operator response was in accordance with the associated plant procedures.
- August 8, Unit 2 shutdown in accordance with procedure 12004-C, Power Operation
- August 15, Unit 2 reactor startup in accordance with procedure 12003-C, Reactor Startup
- August 29, Unit 2 shutdown in accordance with procedure 12004-C, Power Operation
- September 3, Unit 2 reactor startup in accordance with procedure 12003-C, Reactor Startup
- September 27, Unit 1 shutdown in accordance with procedure 12004-C, Power Operation
b. Findings
No findings of significance were identified.
==1R17 Permanent Plant Modifications
a. Inspection Scope
==
The inspectors reviewed Design Change Package (DCP) No. 00-VAN0020-00, Modification to EDG ESF Ventilation Dampers, and DCP 03-V2N0022, Install Canopy Seal Clamp Assembly on Penetration 77, and observed portions of the modification implementations to verify they met the requirements of procedure 58007-C, Design Change Packages. The review was conducted to verify that the modifications did not degrade the system design bases, licensing bases, or performance capability and that plant risk was not increased unnecessarily during implementation of the modifications.
Documents reviewed are listed in the Attachment.
b. Findings
No findings of significance were identified.
==1R19 Post-Maintenance Testing
a. Inspection Scope
==
The inspectors either observed post-maintenance testing or reviewed the test results for the following seven maintenance activities to verify that the testing met the requirements of procedure 29401-C, Work Order Functional Tests, for ensuring equipment operability and functional capability was restored. The inspectors also reviewed the test procedures to verify the acceptance criteria was sufficient to meet the TS operability requirements.

- 2A MDAFW pump mini-flow valve repair (MWO 20302560)
b. Findings
No findings of significance were identified.
==1R20 Refueling and Outage Activities
a. Inspection Scope
==
On August 7, and again on August 29, the licensee initiated a cold shutdown on Unit 2 to investigate and repair RCS leaks. During the outages, the inspectors monitored licensee controls over the outage activities listed below. Documents reviewed are listed in the Attachment.
- Pre-outage risk assessment plan
- Controls associated with shutdown cooling, reactivity management, reduced inventory activities, electrical power alignments, and containment integrity and closure
- Reactor mode changes
- Reactor heatup and repressurization
- Reactor startup activities
b. Findings
Introduction.
A Green self-revealing NCV was identified for failure to maintain a suitable reactor vessel vent path which resulted in inaccurate reactor vessel water level indication and lower than expected reactor vessel level.
Description.
On August 31, with the unit in cold shutdown, temporary RCS level instrumentation and vent hoses were installed to support RCS draindown to one foot below the top of the reactor vessel head. On September 1, following the draindown, during disassembly of a Conoseal on the reactor vessel head, the operators observed an approximately eight inch drop in vessel level as indicated by both the RCS sightglass and RCS wide range level instrument, and a vessel level increase on RVLIS. The licensee walked down the reactor vessel head vent equipment and found an approximately three foot loop seal in the vent hose near the reactor vessel head connection. The licensee was unable to determine when this loop seal formed. The vent hose had been inspected several times during the draindown and no loop seals were noted. The licensee also questioned whether the disc in reactor vessel head vent valve 2-1201-U4-086 was stuck to its seat. The valve relies on spring force to lift and keep the disc off the valve seat. The licensee mechanically agitated the valve to provide additional assurance that the valve was unseated.
Analysis.
The inspectors determined that the RCS level response was indicative of a slightly positive pressure in the reactor head area that was relieved when the Conoseal was breached. It was calculated that actual vessel level was approximately one foot lower than that indicated by the licensees level instrumentation. The inspectors concluded that the licensee had failed to ensure that the reactor vessel head was properly vented during periods of the draindown evolution. This finding is greater than minor because it affected the configuration control attribute of the Initiating Events Cornerstone objective, in that, the failure to maintain a suitable vent path resulted in inaccurate level indication and a perturbation in actual RCS water level. The finding was evaluated using IMC 0609, Appendix G, Shutdown Operations SDP, checklist PWR Cold Shutdown and Refueling Operation RCS Open and Refueling Cavity < 23', and determined to be of very low safety significance because all of the equipment, procedures, and policies that are expected to be maintained in the five shutdown safety functional areas were met. The direct cause of this finding involved the cross-cutting area of Human Performance.
Enforcement.
TS 5.4.1.a requires that written procedures be implemented covering the activities listed in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978, which includes procedures for draining the reactor coolant system. Procedure 12006-C, Unit Cooldown to Cold Shutdown, Revision 60, Section D4.4.7, requires installation of a suitable vent rig at the reactor vessel head vent without any loop seals to establish a vent path from the reactor vessel head to the vent rig isolation valve. Contrary to the above, the licensee failed to take adequate precautions to ensure a suitable vent path was maintained during the RCS draindown and provide accurate vessel level indication.
Because the finding was of very low safety significance and has been entered into the licensees corrective action program as CR 2003002398, this violation is being treated as a NCV in accordance with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000425/2003004-03, Failure to Provide a Suitable Reactor Vessel Vent Results in Inaccurate Reactor Vessel Level Indication.
==1R22 Surveillance Testing
a. Inspection Scope
==
The inspectors reviewed the following six surveillance test procedures and either observed the testing or reviewed test results to verify that testing was conducted in accordance with the procedures and that the acceptance criteria adequately demonstrated that the equipment was operable. This review included two inservice tests (IST) (i.e., surveillance procedures 14803-2 and 14805-1). Additionally, the inspectors reviewed the CR database to verify that the licensee had adequately identified and implemented appropriate corrective actions for surveillance test problems.
- 14980B-1, Diesel Generator Operability Test (1B, fast start)
- 14803-2, CCW Pumps and Check Valves IST and Response Time Tests (Train A)
- 14980B-2, Diesel Generator Operability Test (2B, slow start)
- 14410-2, Control Rod Operability Test
- 14805-1, Residual Heat Removal Pump and Check Valve IST and Response Time Tests (1B RHR pump)
- 28210-C, Main Steamline Code Safety Valve Setpoint Verification (Unit 1)
b. Findings
No findings of significance were identified.
1REP Equipment Availability, Reliability, and Functional Capability (Pilot Procedure)
a. Inspection Scope
Operability Evaluations: The inspectors reviewed the following five evaluations to verify that they met the requirements of procedure 00150-C, Condition Reporting and Tracking System. This scope included a review of the technical adequacy of the evaluations, the adequacy of compensatory measures, and the impact on continued plant operation.
- Unit 2 NSCW fan 2 high vibration (CR 2003001786)
- 2A EDG room fire sprinkler system degradation (CR 2003002039)
- 2A MDAFW pump mini-flow valve failure to open (CR 2003002176)
- Unit 2 containment cooler coating degradation (CR 2003002151)
- Unit 2 RVLIS transmitter leakage inside containment (CR 2003002266)
Operator Work-Arounds: The inspectors assessed the cumulative effects of operator workarounds, i.e., abnormal plant configurations and conditions requiring operator compensation, on the operators ability to effect a correct and timely response to plant transients and events. The inspectors periodically reviewed the Unit 1 and Unit 2 control room logs, caution tag log, abnormal configuration log, MWOs, and the clearance and tagging database, to identify any abnormal configurations. For any abnormal configuration identified, the inspectors evaluated whether they would be considered operator workarounds and could increase the likelihood of an initiating event or could affect multiple mitigating systems.
Maintenance Effectiveness: The inspectors reviewed the following two equipment problems and associated licensee CRs to evaluate the effectiveness of the licensees handling of equipment performance problems and to verify the licensees maintenance efforts met the requirements of 10 CFR 50.65 (the Maintenance Rule) and procedure 50028-C, Engineering Maintenance Rule Implementation. The reviews included adequacy of the licensees failure characterization, establishment of performance criteria or 50.65 (a)
- (1) performance goals, and adequacy of corrective actions.

Through procedure reviews, direct observation of established controls, and interviews with workers, the inspectors evaluated the adequacy of established physical and administrative controls including postings; barricades; procedural guidance; Radiation Work Permits (RWPs); and key controls, as applicable, for High Radiation Areas (HRA),
Locked High Radiation Areas (LHRA), and Very High Radiation Areas (VHRA) locations such as Unit 2 entry into bio-shield at power. The inspectors performed independent confirmatory radiation surveys in selected Auxiliary Building (AB) elevations near the filter vault areas and the Spent Fuel Pool Building. The results of those surveys were compared to current licensee survey documentation. For reviewed tasks, RWP established electronic dosimeter (ED) set points were reviewed for consistency with expected work area dose rates. The inspectors attended pre-job briefings for two at power containment entries conducted during the July 29-30, 2003 period, and assessed the adequacy of information provided to the workers. During tours of the Unit 1 (U1)and Unit 2 (U2) AB areas, the inspectors reviewed implementation of LHRA key controls for selected locations and lift equipment used to remove barriers/shields to waste processing filters and tanks located in the C level filter mezzanines. Controls for access to highly radioactive irradiated materials stored in the spent fuel pool were assessed and discussed with Radiation Protection supervision.
Radiation worker performance with respect to procedural guidance and HPT proficiency were assessed based on interviews and work observations. Knowledge of expected response to ED dose and dose rate alarms was assessed through worker interviews.
Proficiency of HPT staff was evaluated through observation of initial coverage during at power containment entries and conduct of surveys associated with release of materials from the RCA.
The effectiveness of licensee radiation controls were reviewed through review and discussion of selected personnel exposure and contamination event data. Access Control Alarm Reports from January 1 through July 9, 2003, were reviewed to assess the adequacy of ED alarm set-points and guidance provided in five applicable RWPs.
In addition, the maximum worker total effective dose equivalent data for calendar year (CY) 2002 and year-to-date 2003 were reviewed. Occupational exposure data associated with potential radioactive material intakes were reviewed and assessed independently for routine and investigative whole-body count analyses conducted from July 1, 2002, through July 9, 2003. In particular, the inspectors reviewed and assessed worker doses and radiological controls for waste monitor holdup tank maintenance activities conducted April 9, 2003, in accordance with RWP 03-0127, Rev. 1.

Also, the most recent land use census, maximally exposed nearest resident, and applicable dose calculation assumptions were discussed with responsible licensee staff.
License procedures and activities related to environmental monitoring were evaluated for consistency with TS and ODCM details. The inspectors compared NRC GPS determined sampler locations with licensee data, ODCM specifications, and the Annual Radiological Environmental Operating Report details. Documents reviewed are listed in the Attachment.
Meteorological Monitoring Program: The licensees meteorological monitoring program guidance and its implementation was reviewed and evaluated. On July 30, 2003, inspectors toured the meteorological tower and its supporting instrumentation. The inspectors observed the physical condition of the equipment. The inspectors compared system generated data with qualitative observations of wind direction and speed. The inspectors assessed system reliability and data recovery. Meteorological tower siting was evaluated based on near field obstructions, ground cover, proximity to the plant, and distance from terrain that could affect the representativeness of the measurements.
The inspectors reviewed the calibrations and discussed out-of-service sensors for selected meteorological tower instrument sensors used during the previous two years.
License procedures and activities related to meteorological monitoring were evaluated for consistency with Technical Requirements (TR) Manual Section 13.3.3, ODCM, USFAR Section 2.3.3, Onsite Meteorological Measurements Program, and ANS/ANSI 3.11-2000, Determining Meteorological Information at Nuclear Facilities.

4OA2 Identification and Resolution of Problems
a. Inspection Scope
The inspectors reviewed two issues to evaluate the effectiveness of the licensees corrective actions for important safety issues documented in CRs 2002002065 and 2003001731. The condition reports were associated with Agastat timing relays setpoint drifting and a degraded fire penetration. Specifically, the inspectors assessed whether the issues were identified in a timely manner; documented accurately and completely; properly classified and prioritized; adequately considered extent of condition, generic implications, common cause, and previous occurrences; adequately identified root causes; and, identified appropriate corrective actions to prevent recurrence. Also, the inspectors assessed whether the issues were processed in accordance with procedure 00150-C, Condition Reporting and Tracking System, and procedure 00058-C, Root Cause Determination. Documents reviewed are listed in the Attachment.
b. Findings and Observations
No findings of significance associated with the two reviewed issues were identified.
CR 2002002065 - The inspectors determined that the licensee missed an opportunity to utilize industry operating experience (OE) in identifying Agastat relay reliability issues and vendor relay replacement recommendations. Specifically, industry OE, EPRI Report TR-102067, Maintenance and Application Guide for Control Relays and Timers, contained recommended maintenance practices and information that may have led the licensee to replace Agastat relays prior to the relays experiencing setpoint drifting problems. In addition, the inspectors reviewed two CRs (2001000640 and 2001001854)written the previous year that questioned the use of Agastat relays that were beyond their vendor recommended replacement schedule. Again, the inspectors determined that the licensee had missed an opportunity to establish a program to replace Agastat relays prior to the relays having setpoint drifting problems.
CR 2003001731 - The inspectors identified that the licensee was unaware of the need to maintain a fire watch until the silicone foam used to fill and repair a fire penetration boundary was cured for 24-hours. This information is contained in the industry nuclear network as OE 10017 (LER 280-99002) and 10283 (LER 317-98011). The inspectors learned that the licensee considers these types of OE items to be lower tier or low significant OE items, which are distributed via email and are not formally tracked or addressed. The licensee changed procedure 00432-C, Penetration Seal Control, to require fire watches to be maintained until the 24-hour cure time has elapsed.
4OA4 Cross Cutting Aspects of Findings
Section 1R11 describes a finding for failure of operators reactivating their licenses to perform comprehensive tours of all of the required plant areas. The direct cause of this finding involved the cross-cutting area of Human Performance.
Section 1R13 describes a finding for failure to properly assess the increase in risk following the unavailability of RCS level instrumentation during a shutdown outage. The direct cause of this finding involved the cross-cutting area of Human Performance.
Section 1R20 describes a finding for failure to take adequate precautions to ensure a suitable vent path was maintained during an RCS draindown. The direct cause of this finding involved the cross-cutting area of Human Performance.
4OA6 Meetings, Including Exit
On October 3, 2003, the resident inspectors presented the inspection results to Mr. W. Kitchens and other members of his staff, who acknowledged the findings. The inspectors confirmed that proprietary information was not provided or examined during the inspection.
4OA7 Licensee Identified Violations
The following violations of very low safety significance were identified by the licensee and are violations of NRC requirements which meet the criteria of Section VI.A.1 of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as NCVs.
- TS 5.4.1.a requires written procedures to be established and implemented for the applicable procedures recommended in RG 1.33, Rev. 2, Appendix A, February 1978.
Appendix A, specifies that procedures be developed for limiting personnel exposure.
On April 9, 2003, licensee personnel failed to follow guidance for posting and monitoring potential worker exposures for airborne radioactive material conditions associated with U 1 waste holdup tank maintenance activities. As a result, several individuals received unplanned intakes of airborne radioactive materials. This issue was reviewed and documented in Event Report 1-2003-001. This violation is of very low safety significance because doses for the affected individuals were significantly less that regulatory limits.
- TS 5.4.1.c requires written procedures for quality assurance of the effluent monitoring instrumentation to be maintained and implemented. On March 5, 2002, the calibration procedure for count room germanium detectors used to quantitatively determine radionuclide concentrations in effluents was not properly implemented. As a result, from March 5, 2002, until March 20, 2003, three germanium detectors were out of calibration for the charcoal cartridge geometry and the ability to quantitatively analyze for radioactive iodine released in routine airborne effluents was degraded. This event is documented in CR 2003000732. This violation is of very low safety significance because there were no operational events which would have resulted in measurable releases of radioactive iodines during the specified period.
