SUMMARY OF FINDINGS

IR 05000321/2010-002, 05000366/2010-002; 01/01/2010-03/31/2010; Edwin I. Hatch Nuclear Plant, Units 1 and 2, Event Follow-up

The report covered a three-month period of inspection by two resident inspectors, two project engineers, one reactor inspector, and four health physicists. One self-revealing Green finding 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). The cross-cutting aspect was determined using IMC 0305, Operating Reactor Assessment Program. Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review.

Cornerstone: Initiating Events

Green.

A self-revealing finding was identified for the licensee's failure to create, implement, and make available to maintenance personnel, quality processes or documents for configuration control. Specifically, the licensee failed to maintain the correct configuration of the stator water cooling (SWC) temperature control instrument loop air-operated valve, 2N43-F100, as required by licensee procedure NMP-ES-014, Air Operated Valve Program. The failure to implement adequate configuration control on the SWC temperature control instrument loop directly resulted in a Unit 2 reactor scram on June 20, 2009. The licensee has addressed this issue in their Corrective Action Program (CAP) and developed corrective actions in CR 2009106326. As part of the licensee's immediate corrective actions the Unit 2 SWC instrument loop was reconfigured to the correct alignment, and changes were made to procedure NMP-ES-014.

This performance deficiency was more than minor because it was associated with the Configuration Control attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of those events that upset plant stability. Specifically, inadequate configuration control resulted in a Unit 2 reactor scram on June 20, 2009. The significance of this finding was screened using the Phase 1 of the Significance Determination Process (SDP) in accordance with NRC Inspection Manual Chapter 0609 Attachment 4. Because the finding contributed to a reactor scram, but did not affect mitigation equipment availability, the finding screened as

Green.

This finding had a cross-cutting aspect in the Resources component of the Human Performance area, because the licensee did not provide complete, accurate and up-to-date design documentation, procedures, and work packages, and correct labeling of components. Specifically, the licensee did not implement a means of configuration control of the SWC temperature control instrument loop. (H.2(c)). (Section 4OA3.1)

RADIATION SAFETY

Cornerstones: Occupational Radiation Safety and Public Radiation Safety

2RS1 Radiological Hazard Assessment and Exposure Control

a. Inspection Scope

Radiological Hazard Assessment. The inspectors reviewed a number of radiological surveys, including those performed for airborne areas, of locations throughout the facility including the Unit 1 (U1) drywell, U1 and Unit 2 (U2) reactor buildings, and the independent spent fuel storage installation (ISFSI). The inspectors also walked down those same areas and radioactive material storage locations with a survey instrument, evaluating material condition, postings, and radiological controls. The inspectors observed jobs in radiologically risk-significant areas including high radiation areas and areas with, or with the potential for, airborne activity. The inspectors determined that the surveys were adequate in thoroughness and frequency for the identified hazards.

Instructions to Workers. During plant walk downs, the inspectors observed labeling and radiological controls on containers of radioactive material. The inspectors also reviewed radiation work permits (RWP) used for accessing high radiation areas and airborne areas, verifying that appropriate work control instructions and electronic dosimeter (ED) setpoints had been provided and to assess the communication of radiological control requirements to workers. For selected tasks, the inspectors attended pre-job briefings that reviewed RWP details with the workers. The inspectors reviewed selected ED dose and dose rate alarms, to verify workers properly responded to the alarms and that the licensee's review of the events was appropriate. Through observation of pre-job RWP briefings and health physics technician coverage of workers, the inspectors determined the licensee had established adequate means to notify workers of changing radiological conditions.

Contamination and Radioactive Material Control: The inspectors observed the release of potentially contaminated items from the radiologically controlled area (RCA) and from contaminated areas such as the drywell. The inspectors also reviewed the procedural requirements for, and equipment used to perform, the radiation surveys for release. During plant walk downs, the inspectors evaluated radioactive material storage areas and containers, including satellite RCAs, assessing material condition, posting/labeling, and control of materials/areas. In addition, the inspectors reviewed the sealed source inventory and verified labeling, storage conditions, and leak testing of selected sources.

The inspectors walked-down the ISFSI facility, observing the physical condition of the casks, radiological postings, and barriers. The inspectors performed independent gamma radiation surveys of the area and reviewed gamma radiation surveys of the ISFSI facility performed by licensee personnel. Inspectors compared the independent survey results to previous surveys and against procedural and Technical Specification (TS) limits. The inspectors evaluated implementation of radiological controls, including labeling and posting, and discussed controls with health physics staff. Environmental monitoring results for direct radiation from the ISFSI were reviewed and inspectors observed the placement and physical condition of thermoluminescent dosimeters around the facility.

Radiological Hazards Control and Work Coverage. The inspectors evaluated licensee performance in controlling worker access to radiologically significant areas and monitoring jobs in-progress associated with the U1 refueling outage. Established radiological controls were evaluated for selected tasks including main steam isolation valve work, safety-relief valve work, scaffolding, and control rod drive hydraulic control unit maintenance. The inspectors evaluated the effectiveness of radiation exposure controls, including air sampling, barrier integrity, engineering controls, and postings through a review of both internal and external exposure results.

During walk downs with a radiation survey meter, the inspectors independently verified ambient radiological conditions were consistent with licensee performed surveys, RWPs, and pre-job briefings; observed the adequacy of radiological controls; and observed controls for radioactive materials stored in the spent fuel pool. The inspectors also reviewed the procedural guidance for multi- and extremity badging. Select multi-badge packets were reviewed to verify consistency with procedural and regulatory guidance. For high radiation area tasks involving significant dose rate gradients, the inspectors evaluated the use and placement of whole body and extremity dosimetry to monitor worker exposure. The inspectors also reviewed and discussed selected whole-body count analyses conducted during 2009 and the current U1 refueling outage. The inspectors reviewed RWPs for use in airborne areas, ensuring the prescribed controls were appropriate for the conditions as identified in radiological surveys and air samples. ED alarm set points and worker stay times were evaluated against area radiation survey results for drywell and refueling floor activities.

Risk-Significant High Radiation Area and Very High Radiation Area Controls. The inspectors discussed the controls and procedures for locked-high radiation areas (LHRAs) and very high radiation areas (VHRAs) with health physics supervisors and the radiation protection manager. The inspectors observed the issuance of LHRA keys and evaluated the storage, inventory, and handling of LHRA/VHRA keys. During plant walk downs, the inspectors verified the posting/locking of LHRA/VHRA areas.

Radiation Worker Performance and Radiation Protection Technician Proficiency. The inspectors observed radiation worker performance through direct observation and in the remote monitoring center. Jobs observed included main steam isolation valve work, safety-relief valve work, scaffolding, and control rod drive hydraulic control unit maintenance. These jobs were performed in high radiation, airborne, and/or contaminated areas. The inspectors also observed health physics technicians providing field coverage of jobs and providing remote coverage from the central monitoring center.

Problem Identification & Resolution. Licensee Corrective Action Program (CAP) documents associated with access control to radiologically significant areas were reviewed and assessed. This included review of selected Condition Reports (CRs) related to radworker and health physics technician performance. The inspectors evaluated the licensee's ability to identify, characterize, prioritize, and resolve the identified issues in accordance with procedure NMP-GM-002, Corrective Action Program, Ver. 9.0. The inspectors also evaluated the scope of the licensee's internal audit program and reviewed recent assessment results. Licensee CAP documents reviewed are listed in Section

2RS1 of the report Attachment.

Radiation protection activities were evaluated against the requirements of Updated Final Safety Analysis Report (UFSAR) Section 12; TS Sections 5.4 and 5.7; 10 Code of Federal Regulations (CFR) Parts 19 and 20; and approved licensee procedures. Radiological control activities for ISFSI areas were evaluated against 10 CFR Part 20, 10 CFR Part 72, and TS details. Records reviewed are listed in Section

2RS1 of the Attachment.

The inspectors completed 1 sample, as described in Inspection Procedure (IP) 71124.01. The inspectors also completed the radiation protection line-item sample activities specified in IP 60855.1.

2RS5 Radiation Monitoring Instrumentation

a. Inspection Scope

Radiation Monitoring Instrumentation. During tours of the Unit 1 (U1) and Unit 2 (U2) Reactor Buildings, Spent Fuel Pool Areas, U2 Turbine Building and Radwaste Building, the inspectors observed installed radiation detection equipment including the following instrument types: Area Radiation Monitors (ARMs), Continuous Air Monitors (CAMs), Personnel Contamination Monitors (PCMs), Portal Monitors (PMs), Small Article Monitors (SAMs). The inspectors observed the physical location of the components, noted the material condition, and compared sensitivity ranges with UFSAR requirements. Select ARMs with local readouts were compared with actual radiological conditions for consistency.

In addition to equipment walk-downs, the inspectors observed functional checks and alarm set point testing of various fixed and portable detection instruments, including portable ion chambers, AMP-100s, teletectors, PCMs, PMs and small article monitors (SAMs). Select calibration records for PCMs, PMs, SAMs, portable survey instruments, air samplers, ARMs and electronic personnel dosimeters were reviewed.

The inspectors reviewed calibration records, source check data and the material condition of instruments in the licensee's radiation protection instrument issue area, including portable ion chambers, underwater survey meters, neutron survey meters and portable GM detectors. The inspectors reviewed records of portable survey instruments that failed to meet the source acceptance criteria to verify the appropriateness of corrective actions. Daily performance checks and calibration data for HP laboratory equipment used for alpha and beta counting were reviewed.

The most recent 10 CFR Part 61 analyses and Whole Body Counter Calibration were reviewed to determine if calibration and check sources were representative of the plant isotopic mix. The inspectors reviewed records for the licensee's portable survey and ARM instrument calibrator and verified measuring devices were calibrated with NIST traceable sources. The last two calibration records for the U1 low range (1D11-K622) and the U1 High-range (1D11-K621) post accident monitors were reviewed.

The inspectors reviewed performance records and calibration results for selected process and effluent radiation monitors. The inspectors verified that the channel calibration and functional tests were performed consistent with radiological effluent technical specifications and National Institute of Standards and Technology (NIST)traceable standards. During the inspection, the inspectors observed the calibration of POST-LOCA monitors 1D11-K624, 1D11-K625, and 1D11-K626.

The inspectors reviewed selected laboratory analytical instruments used for radiological analysis in the chemistry lab areas. The inspectors observed the daily performance checks of those counting instruments used in the chemistry lab areas and discussed those results with cognizant licensee representatives.

Operability and reliability of selected radiation detection instruments were reviewed against 10 CFR Part 20; TS Section 5.4, Procedures; UFSAR Chapters 11 and 12; and applicable licensee procedures. Documents reviewed during the inspection are listed in Section

2RS5 of the Attachment.

Electronic Dosimetry. The inspectors reviewed the licensee's calibration methodology for Electronic Personal Dosimeters (EPDs) that included the radioactive sources, traceable standards, and tolerance levels used during EPD calibration.

Problem Identification and Resolution. Selected Condition Reports (CRs) associated with effluent release activities and radiation protection instrumentation were reviewed and assessed. The inspectors evaluated the licensee's ability to identify, characterize, prioritize, and resolve selected issues in accordance with procedure NMP-GM-002, Corrective Action Program, Rev 9.0. The inspectors also evaluated the scope of the licensee's internal audit program and reviewed recent assessment results. Reviewed documents are listed in Section

2RS5 of the Attachment.

The inspectors completed 1 of the 1 required samples detailed in IP 71124.05. All samples have now been completed for this IP.

b. Findings

The inspectors reviewed calibration records for EPDs at the licensee's facility. The licensee's EPDs were found to be capable of measuring Deep Dose Equivalent (DDE) and Shallow Dose Equivalent (SDE). The SDE feature was disabled and not used during routine radiological monitoring. EPDs were primarily used to estimate worker exposure for DDE, but were also used as a method of controlling worker exposure for entries in High Radiation Areas in accordance with TS 5.7.1b.

The inspectors identified three different methods used to calibrate EPDs. New EPDs purchased directly from the manufacturer were calibrated to a tolerance level of +/-10%

of a known Cs-137 source traceable to a United Kingdom National Standard. Subsequent calibrations were performed by the licensee's Environmental Laboratory to respond to a tolerance level of +/- 15% of a known Cs-137 source traceable to NIST. EPDs that required repair were sent to a calibration vendor located in West Columbia, South Carolina for repair and subsequently calibrated at that facility to a tolerance level of +/-10% using an Am-241 source traceable to NIST.

Licensee procedure 60AC-HPX-017-0, Radiation Protection Instrumentation Program, required radiation survey instruments used to assign or control worker exposure be initially and subsequently calibrated to read within +/-10% of the actual calibration source dose rates using radiation sources traceable to NIST. Additionally, 10 CFR 20.1501

(b) requires licensees to ensure that instruments and equipment used for quantitative radiation measurements (e.g., dose rate and effluent monitors) are calibrated periodically for the radiation measured. Although the EPD is not generally used as a substitute for typical dose rate survey meters, it is used to initiate worker actions in lieu of a survey meter in accordance with TS 5.7.1.b which requires incorporation of the EPD into the routine instrument calibration program.

From a review of licensee records and discussions with cognizant licensee representatives, the inspectors determined that the licensee had not established a site specific standard for calibrating EPDs or compared the response of the EPDs using the different sources. The use of an Am-241 source, a low level gamma emitter was not representative of the energy ranges in the licensee's isotopic mix. In addition, the inspectors determined that the calibrations performed by the licensee's environmental laboratory were not consistent with the licensee's calibration methods for other instruments used to control worker exposure.

This item is unresolved pending NRC review of the licensee's evaluation of the EPDs response using NIST traceable sources representative of the energy spectrum of radiation fields at the licensee's facility and a review of the licensee's specific calibration method for EPDs.

4OA3 Event Follow-up

(Closed) LER 05000366/2009-003 Main Generator Runback Due to High Stator Cooling Water Temperature

a. Inspection Scope

On June 20, 2009, a Unit 2 automatic reactor scram was initiated on high reactor pressure when a main generator runback due to high stator water cooling outlet temperature occurred. The licensee identified that the cause of the main generator high stator cooling outlet temperature was due to improper set-up of the stator cooling water temperature control instrument loop. The inspectors reviewed this LER, the licensee's root cause report and associated corrective actions.

b. Findings

Introduction

A Green self-revealing finding was identified for the licensee's failure to create, implement, and make available to maintenance personnel, quality processes or documents for configuration control. Specifically, the licensee failed to maintain the correct configuration of the stator water cooling (SWC) temperature control instrument loop air-operated valve, 2N43-F100, as required by licensee procedure NMP-ES-014, Air Operated Valve Program. The failure to implement adequate configuration control on the SWC temperature control instrument loop directly resulted in a Unit 2 reactor scram on June 20, 2009. (LER 05000366/2009-003)

Description

On June 20, 2009, Unit 2 was in mode 1 at approximately 100% reactor power. Protective circuitry initiated a main generator runback due to high SWC outlet temperature. As a result, the electro-hydraulic control (EHC) processor began reducing turbine load by closing the turbine control valves and subsequently opening the turbine bypass valves. Operations personnel immediately began reducing reactor power in response to the main generator runback by reducing recirculation flow. The reactor power was reduced to approximately 66% reactor thermal power and could not be reduced any further without the insertion of control rods. As a result of turbine load reducing faster than the manual actions taken to reduce reactor power, reactor pressure began to increase. Pressure reached the setpoint to actuate the Reactor Protection System, and an automatic reactor scram was initiated due to high reactor pressure.

The cause of high SWC outlet temperature on the main generator was a result of improper set-up of the SWC temperature control instrument loop during the previous outage, (2R20). Air Operated Valve (AOV) 2N43-F100, which controls temperature by directing flow to the SWC heat exchangers, was on full bypass when it should have been providing flow through the heat exchanger given the system operating temperature at the time. Since Unit 1 SWC positioner is configured the same, Unit 1 was inspected to ensure that the positioner and controller were set up correctly.

During the 2R20 refueling outage on Unit 2, maintenance personnel performed preventive maintenance (PM) on the SWC temperature control instrument loop. This PM consisted of a calibration of 2N43-R310 (temperature controller), performed every 2 years and refurbishment of 2N43-F100 (actuator), performed every 12 years. AOV 2N43-F100 was a reverse design, spring return, three way valve. The proper configuration should have been "Direct" action for the temperature controller (2N43-R310) and "Reverse" action for the actuator (2N43-F100). Under a "Direct/Reverse" configuration set-up, the temperature controller (2N43-R310) would have sent maximum "open signal" to the actuator (2N43-F100). During the 2R20 PM's, the actuator (2N43-F100) was incorrectly set-up as "Direct" action. The "Direct/Direct" configuration would not allow the valve to function per design, essentially increasing the bypass flow around the heat exchanger.

Southern Nuclear Operating Company, NMP-ES-014, Air Operated Valve Program, Version 5.0, provides program requirements for all AOV's onsite. Per this program all AOV's are to be categorized as either 1, 2, or 3 based upon its contribution to safe plant operation or accident mitigation. Depending on the category this program will define the extent of design review and testing activities to be performed. Contrary to the requirements of NMP-ES-014 the licensee failed to create, implement, and make available to maintenance, quality processes or documents that would control and identify the correct configuration of the SWC temperature control instrument loop as required for CAT 3 AOV's such as 2N43-F100. The licensee has addressed this issue in their Corrective Action Program (CAP) and developed corrective actions in CR 2009106326. As part of the licensee's immediate corrective actions the Unit 2 SWC instrument loop was reconfigured to the correct alignment, and changes were made to procedure NMP-ES-014.

Analysis:

Failure to implement adequate configuration control of the SWC temperature control instrument loop as required per licensee procedure NMP-ES-014, was a performance deficiency. This performance deficiency was more than minor because it was associated with the Configuration Control attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of those events that upset plant stability. Specifically inadequate configuration control resulted in a Unit 2 reactor scram on June 20, 2009. The significance of this finding was screened using the Phase 1 of the Significance Determination Process (SDP) in accordance with NRC Inspection Manual Chapter 0609 Attachment 4. Because the finding contributed to a reactor scram, but did not affect mitigation equipment availability, the finding screened as Green.

The inspectors determined this performance deficiency was indicative of current licensee performance, in that this event occurred during the last refueling outage (2R20). Also, as indicated in the Root Cause Investigation for CR 2009106326, work packages that controlled the set-up of the SWC temperature control instrument loop have been inconsistent or incorrect since 2000. Therefore, this finding had a cross-cutting aspect in the Resources component of the Human Performance area, because the licensee failed to provide complete, accurate and up-to-date design documentation, procedures, work packages, and correct labeling of components. Specifically, the licensee failed to implement a means of configuration control of the SWC temperature control instrument loop (H.2(c)).

Enforcement

Enforcement action did not apply because the performance deficiency did not involve a violation of regulatory requirements due to it being associated with the non-safety related Main Generator Stator Water Cooling system. Because this finding did not involve a violation of regulatory requirements and had very low safety significance, it was identified as FIN 05000366/2010002-02, "Failure to implement adequate configuration control on Unit 2 main generator stator water cooling temperature control instrument loop, 2N43-F100."
