Mr. William R. Campbell, Jr. Chief Nuclear Officer and Executive Vice President Tennessee Valley Authority 6A Lookout Place 1101 Market Street Chattanooga, TN 37402-2801
SUBJECT: BROWNS FERRY NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000259/2008003, 05000260/2008003 AND 05000296/2008003
Dear Mr. Campbell:
On June 30, 2008, the U. S. Nuclear Regulatory Commission (NRC) completed an inspection at your Browns Ferry Nuclear Plant, Units 1, 2, and 3. The enclosed inspection report documents the inspection results which were discussed, on July 2 and 17, 2008, and on August 4, 2008, with Mr. Rusty West and Mr. Steve Douglas and Mr. James Emens, respectively, and with other members of your staff. The inspection examined activities conducted under your licenses as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your licenses. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel. In addition to the routine Reactor Oversight Process baseline inspections for all three units, the inspectors continued to conduct augmented inspections on Unit 1 as delineated in NRC letters dated May 16 and December 6, 2007. These Unit 1 augmented inspections were conducted to compensate for the lack of valid data for certain Performance Indicators (PIs). These additional inspections were only considered to be an interim substitute for the invalid Unit 1 PIs until complete and accurate PI data is developed and declared valid. However, since Unit 1 startup on May 22, 2007, the PIs in the Initiating Events and Barrier Integrity cornerstones, and the Safety System Functional Failure PI of the Mitigating Systems cornerstone, have since become valid as acknowledged by the Tennessee Valley Authority letter dated January 7, 2008. Consequently, the only PIs that remained invalid, and thereby subject to the augmented baseline inspection, were the Mitigating Systems Performance Index PIs. This report documents two self-revealing and one NRC-identified findings which were determined to involve a violation of NRC requirements. However, because these three findings were of very low safety significance and were entered into your corrective action program, the NRC is treating these violations as non-cited violations (NCV) consistent with Section VI.A of the NRC Enforcement Policy. If you contest any NCV in the enclosed report, you should provide TVA 2 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 Senior Resident Inspector at the Browns Ferry Nuclear Plant. 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 NRC's document system (ADAMS).

SUMMARY OF FINDINGS
IR 05000259/2008003, 05000260/2008003 and 05000296/2008003; 04/01/2008 - 06/30/2008; Browns Ferry Nuclear Plant, Units 1, 2 and 3; Occupational and Public Radiation Safety and Other Activities.
The report covered a three-month period of routine inspections by the resident inspectors, two senior health physicists, a health physicist and a senior reactor inspector. Three Green NCVs were identified. The significance of most findings are 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 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 4, dated December 2006.
A. NRC-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
The NRC identified a Green non-cited violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for the licensee's failure to identify and correct deficiencies in watertight doors that protect the safety-related Residual Heat Removal Service Water pumps and Emergency Equipment Cooling Water pumps from external flooding. The licensee issued work orders to correct the conditions and entered the issue into their corrective action program as Problem Evaluation Reports 133891 and 134346.
This finding was more than minor because it affects the External Factors (Flood Hazard) attribute of the Mitigating Systems Cornerstone. It impacted the cornerstone objective of ensuring the availability, reliability, and operability of safety-related pumps to perform their intended safety function during a design basis flooding event. A Significance Determination Process Phase 3 analysis determined that the finding was of very low safety significance because of the low likelihood of the design basis flood. The finding was directly related to the cross-cutting aspect of procedural compliance of the work control component of the cross-cutting area of Human Performance. Mechanics were not complying with quarterly work orders and maintenance procedure to assure functionally of the watertight doors (H.4(b)). (Section 4OA5.1)
Cornerstone: Occupational Radiation Safety
- Green.
A Green, self-revealing non-cited violation of Technical Specification (TS) 5.7.1 was identified for the licensee's failure to conspicuously post, barricade, and control access to a high radiation area (HRA) with dose rates not exceeding 1.0 rem per hour at 30 centimeters from the source. On June 13, 2007, operations personnel raised Unit 1 reactor power from 25 percent rated thermal power (RTP) to 34 percent RTP, resulting in general area dose rates in the Unit 1 turbine building moisture separator room increasing to greater than 100 millirem/hour (mrem/hr), making it an HRA. But contrary to TS 5.7.1., the room was posted and controlled as a radiation area at the time of the power increase. Three individuals working in the room received electronic dosimeter dose rate alarms of 140 mrem/hr, 212 mrem/hr, and 215 mrem/hr. Once the change in radiological conditions was recognized, radiological control personnel immediately posted and controlled the work area as an HRA. The finding was entered into the licensee's corrective action program as Problem Evaluation Report 126211. This finding was more than minor because it was associated with the Occupational Radiation Safety cornerstone attribute of exposure control and it affected the associated cornerstone objective because the failure to post, barricade, and control access to an HRA did not ensure the adequate protection of worker health and safety from exposure to radiation. The finding was evaluated using the Occupational Radiation Safety Significance Determination Process and was determined to be of very low safety significance because the finding did not involve a substantial potential for overexposure and did not affect the ability to assess dose. The cause of this finding was directly related to the work activity coordination cross-cutting aspect in the work control component of the Human Performance cross-cutting area because operations and health physicists personnel failed to effectively communicate and coordinate the activities associated with the power increase (H.3(b)). (Section 2OS1)
Cornerstone: Public Radiation Safety
- Green.
A Green, self-revealing non-cited violation of 10 CFR 20.1801 was identified for the licensee's failure to secure stored radioactive material from unauthorized removal. On August 14, 2007, a shipment of "clean" scrap metal from Browns Ferry alarmed the truck monitor at a vendor recycling facility. Using a hand-held survey instrument, the vendor identified the contaminated item to be a small (4 ounces) metal can containing pipe threading compound. Subsequently, upon arrival at the site, licensee personnel retrieved the item and performed radiation surveys as necessary. The finding was entered into the licensee's corrective action program as Problem Evaluation Report 128870.
This finding was more than minor because it was associated with the Public Radiation Safety cornerstone attribute of program and process and it affected the associated cornerstone objective because the failure to secure stored radioactive material from removal did not ensure the adequate protection of public health and safety from exposure to radiation. The finding was evaluated using the Public Radiation Safety Significance Determination Process and was determined to be of very low safety significance because the failure to secure radioactive material from removal was a finding in the radioactive material control program that did not result in a public exposure exceeding 5 mrem. The cause of this finding was related to the evaluation of identified problems cross-cutting aspect in the corrective action component of the Problem Identification and Resolution cross-cutting area because evaluations performed by the licensee subsequent to previous radioactive material control events had failed to thoroughly evaluate and identify the weaknesses in the radioactive material control program (P.1(c)). (Section 2PS3)
B. Licensee-Identified Violations
None.
REPORT DETAILS
Summary of Plant Status Unit 1 operated at essentially full rated thermal power (RTP) the entire report period except for two planned downpowers. On April 19, 2008, Unit 1 reduced power to 70 percent RTP to fully withdraw a control rod, clean waterboxes, and adjust rod sequence. The unit was returned to full RTP the next day. On May 18, 2008, Unit 1 reduced power to 78 percent RTP to repair an 1B3 reactor feedwater (RFW) heater leak. The unit was returned to full power on May 22, 2008.
Unit 2 operated at essentially full power the entire report period except for several planned downpowers. On April 12, 2008, Unit 2 reduced power to 92 percent RTP for RFW heater leak repairs, and main turbine generator control valve testing. The unit was returned to full RTP the next day.

Unit 3 entered Mode 2 on May 15, 2008, achieved full RTP on May 19, 2008, and remained at full RTP throughout the rest of the report period.
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity
1R01 Adverse Weather Protection
.1 Offsite and Alternate Alternating Current (AC) Power Systems Readiness
a. Inspection Scope
Prior to the summer season, inspectors reviewed electrical power design features, onsite risk and work management procedures, and corporate transmission and power supply procedures to verify appropriate operational oversight and assurance of continued availability of offsite and onsite alternate AC power systems. Inspectors verified that communication protocols existed between the transmission system operator and Browns Ferry Nuclear Plant for coordination of off-normal and emergency events affecting the plant, including event details, estimates of return-to-service times, and notifications of grid status changes. Inspectors also verified that procedures included controls to adequately monitor both offsite AC power systems (including post-trip voltages) and onsite alternate AC power systems for availability and reliability. Furthermore, inspectors interviewed onsite licensed operators and offsite transmission personnel to determine their understanding and implementation of the power monitoring and assessment process.
b. Findings
No findings of significance were identified.
.2 Readiness for Seasonal Extreme Weather Conditions (Hot Weather Preparations)
a. Inspection Scope
Prior to and during the onset of hot weather conditions, the inspectors reviewed the licensee's implementation of 0-GOI-200-3, Hot Weather Operations, including checklist Attachment 1, Hot Weather Operational Checklist. The inspectors also reviewed Browns Ferry Work Order Report PA-104 for Hot Weather Focus Areas and discussed implementation of 0-GOI-200-3 with responsible Operations personnel and management. Additionally, the inspectors conducted walkdowns of potentially affected risk significant equipment systems located in the common Residual Heat Removal Service Water (RHRSW) and Emergency Equipment Cooling Water (EECW) Rooms, and the three units Refueling and Reactor Zone Supply Fan Rooms. Furthermore, the inspectors reviewed licensee procedure 0-GOI-200-1, Attachment 14, Restoration from Freeze Protection, for verification of licensee actions to recover from cold weather conditions in preparation for hot weather conditions.
b. Findings
No findings of significance were identified.
.3 Readiness for Impending Adverse Weather Conditions
a. Inspection Scope
On April 4, a Tornado Warning for Limestone County (without a prior Watch condition), and on May 8, a Tornado Watch, and then a Tornado Warning (for an adjacent county -
Lauderdale County), were declared. For both of these events, the inspectors reviewed the licensee=s overall preparations/protection for the unexpected onset of severe weather conditions and observed the licensee's implementation of abnormal operating instruction (AOI) 100-7, Severe Weather, including parallel implementation of actions for Tornado Watch and Warning. Inspectors observed applicable contingency actions associated with Unit 3 in a refueling outage and the subsequent elevation of shutdown risk to level Orange. The inspectors also reviewed and discussed the implementation of AOI 100-7 with the responsible Unit Supervisor (US), Outage Control Center Supervisor, and shift manager (SM). Furthermore, the inspectors witnessed the licensee's execution of evacuation orders of vulnerable areas and buildings outside the power block, and the termination of work and evacuation of the turbine building and refueling floor. The inspectors also verified adequate operator staffing and their accessibility to controls and indications for those systems required for safe control of the plant.

The inspectors reviewed plant design features and measures intended to protect the plant and its safety-related equipment from internal cross-unit flooding events, as described in the Updated Final Safety Analysis Report (UFSAR), general design criteria, the internal flooding notebook, and various surveillance and alarm response procedures.
The inspectors conducted walkdowns of all units' reactor building 519' elevation reactor bulkhead airlocks (eight total) and associated corner rooms, to review flood-significant features such as door operating mechanisms and gaskets, airlock bulkhead inter-seal conditions, and door seal thresholds that might be subjected to flood conditions. Plant procedures for mitigating flooding events were also reviewed to verify that licensee actions were consistent with the plant's design basis assumptions. Furthermore, the inspectors reviewed a sampling of the licensee's corrective action documents with respect to flood-related items to verify that problems were being identified and corrected.
b. Findings
No findings of significance were identified.
1R07 Heat Sink Performance
a. Inspection Scope
The inspectors examined the licensee's implementation of biofouling controls associated with all three units' RHRSW heat exchangers. The inspectors reviewed procedures used for continuous EECW chemical injection, periodic RHRSW chemical injection, and establishment of adequate heat exchanger flow rates. The inspectors also reviewed Electric Power Research Institute (EPRI) heat exchanger performance monitoring guidelines and licensee raw water inspection records to evaluate the licensee's program for maintaining heat sinks. Furthermore, the inspectors reviewed related PERs and corrective actions to verify that the licensee was identifying issues and correcting them.
The inspectors performed walkdowns of chemical addition systems and RHRSW/EECW interfaces to verify material conditions were acceptable and physical arrangements matched procedures. The inspectors also observed operations personnel align RHRSW heat exchangers for chemical injections in accordance with procedures to minimize excessive outlet valve vibration and erosion. Furthermore, the inspectors reviewed the documented results of the last periodic raw water inspection for each RHRSW heat exchanger to verify that monitoring related to the EPRI guidance was adequate and that issues were being addressed within the CAP.
b. Findings
No findings of significance were identified.
1R11 Licensed Operator Requalification
.1 Resident Inspector Quarterly Review
a. Inspection Scope
On May 21, 2008, the inspectors observed licensed operator requalification simulator examination for two crews. Each crew received the same examination scenario: "Dual Recirculation Pump Trip with Stuck Open SRV." The inspectors specifically evaluated the following attributes related to each operating crew's performance:
- Clarity and formality of communication
- Ability to take timely action to safely control the unit
- Prioritization, interpretation, and verification of alarms
- Correct use and implementation of AOIs, and Emergency Operating Instructions (EOIs)
- Timely and appropriate Emergency Action Level declarations per Emergency Plan Implementing Procedures (EPIP)
- Control board operation and manipulation, including high-risk operator actions
- Command and Control provided by the US and SM The inspectors attended a post-examination critique to assess the effectiveness of the licensee evaluators, and to verify that licensee-identified issues were comparable to issues identified by the inspector. The inspectors also reviewed simulator physical fidelity (i.e., the degree of similarity between the simulator and the reference plant control room, such as physical location of panels, equipment, instruments, controls, labels, and related form and function).

1R20 Refueling and Other Outage Activities
.1 Unit 3 Scheduled Refueling Outage (U3C13)
a. Inspection Scope
From March 18 through May 19, 2008, the inspectors examined critical outage activities associated with the U3C13 refueling outage and Unit 3 restart to verify that they were conducted in accordance with TS, applicable procedures, and the licensee's outage risk assessment and management plans. Refueling outage activities that occurred prior to March 31 were documented in NRC inspection report (IR) 05000296/2008002. Since April 1, the inspectors reviewed and examined selected refueling outage and power ascension activities. Some of the more significant critical outage activities observed and/or examined by the inspectors, were as follows:
- Control of Hot Shutdown (Mode 3), Cold Shutdown (Mode 4), Startup (Mode 2), and Power Operation (Mode 1) conditions, including critical plant parameters
- Restoration of off-site power to backfeed Unit 3 following main generator breaker repairs
- Plant Oversight Review Committee event review and restart meetings on May 9 and 11, and the final restart approval on May 13
- Clearance tagging controls during maintenance and testing of safety-related equipment
- Reactor vessel disassembly and reassembly, and reactor cavity level controls
- 3EC standby diesel generator load acceptance test
- Unit 3 Cycle 14 Core Reload Verification Video Tape
- Control rod scram time testing
- ASME Section XI system leakage test of the reactor pressure vessel and associated piping following heatup and pressurization of Unit 3
- Reactor startup and power ascension activities per General Operating Instruction (GOI) 3-GOI-100-1A, Unit Startup, including rod withdrawal for criticality, reactor coolant system heatup, initial turbine roll, and synchronization of the main generator

- Control and management of emergent work activities Drywell and Suppression Pool Closeout On May 1 and 2, the inspectors performed an independent detailed closeout inspection of the Unit 3 Suppression Pool, including emergency core cooling system suction strainer conditions, and verification of foreign material exclusion (FME) control. The inspectors also observed and reviewed the licensee's final FME verification for hatch closure in accordance with MSI-0-064-HLT002, Opening and Closing Primary Containment Hatches.
On May 9 and 13, the inspectors performed an independent detailed closeout inspection of all Unit 3 Drywell elevations. The inspectors also reviewed and verified the licensee's conduct of 3-GOI-200-2, Drywell Closeout. Outage Risk Assessment During the Unit 3 62 day U3C13 refueling outage that ended on May 19, the inspectors verified that the licensee appropriately maintained adequate defense-in-depth measures for all critical safety functions. The inspectors also reviewed the daily U3C13 Refueling Outage Reports, including the Outage Risk Assessment Management Safety Function Status, and frequently attended the twice a day outage status meetings. These reviews were compared to the requirements in licensee procedure SPP-7.2, Outage Management, the Outage Risk Assessment Report, and TS. The inspectors' reviews and walkdowns also verified that for identified high risk significant conditions (i.e., Orange), due to equipment availability and/or system configurations, that contingency measures and RMAs were identified and implemented by the overall outage and contingency response plan. Furthermore, the inspectors frequently discussed risk conditions and designated protected equipment with Operations and outage management personnel to assess licensee awareness of actual risk conditions and mitigation strategies.
Decay Heat Removal The inspectors reviewed licensee procedures 3-OI-74, Residual Heat Removal System; 3-OI-78, Fuel Pool Cooling and Cleanup System; and 0-AOI-72-1, Alternate Decay Heat Removal (ADHR) System Failures; and conducted a main control room panel and in-plant walkdowns of system and components to verify correct system alignment. In addition, the inspectors monitored licensee work controls to ensure that outage work would not adversely impact the ability of operators to operate spent fuel pool (SFP) cooling, RHR shutdown cooling, and/or ADHR systems when these systems were required. Furthermore, the inspectors conducted several walkdowns of the ADHR system during operation with the fuel pool gates removed.
Outage Activities On a routine basis, the inspectors observed and monitored ongoing outage activities to verify that they were conducted in accordance with TS, licensee procedures, and the licensee's outage risk control plan. Some of the more significant routine inspection activities accomplished by the inspectors were as follows:

RADIATION SAFETY
Cornerstones: Occupational Radiation Safety and Public Radiation Safety 2OS1 Access Control To Radiologically Significant Areas
a. Inspection Scope
Access Controls: The inspectors reviewed and evaluated licensee guidance and its implementation for controlling and monitoring worker access to radiologically significant areas and tasks associated with Unit 1, Unit 2, and Unit 3 operations and the U3C13 refueling outage. The inspectors evaluated changes to, and adequacy of, procedural guidance; directly observed implementation of established administrative and physical radiation controls; appraised radiation worker (radworker) and health physics technician (HPT) knowledge of, and proficiency in, implementing radiation protection (RP) activities; and assessed radworker exposures to radiation and radioactive material. The inspectors directly observed controls established for radworker and HPT staff in actual or potential airborne radioactivity area, radiation area, high radiation area (HRA), and locked HRA (LHRA) locations. Established radiological controls were evaluated for selected U3C13 tasks including shielding, scaffolding, torus diving, fuel movement, control rod drive exchange, and undervessel work. Postings and physical controls established within the radiologically controlled area for access to the Unit 3 drywell, Unit 1, Unit 2, and Unit 3 reactor building and turbine building locations, and radioactive waste processing and radioactive material storage areas were evaluated directly during facility tours. The inspectors independently measured radiation dose rates during these tours. In addition, the inspectors directly observed conduct of licensee surveys and results of radiation levels, airborne radionuclide concentrations, and/or surface contamination levels for select areas and equipment associated with outage activities. Results were compared to current licensee surveys and assessed against established postings and established radiation controls. The inspectors also reviewed select radiological controls and data associated with a Unit 1 power ascension on June 13, 2007. For select tasks, the inspectors attended pre-job briefings and reviewed radiation work permit (RWP) details to assess communication of radiological control requirements to workers. Radworker adherence to select RWPs and HPT proficiency in providing job coverage were evaluated through direct observations and interviews with licensee staff. Direct reading dosimeter (DRD) equipment alarm set-points were evaluated against area radiation survey results for select outage and routine operations activities.
The inspectors walked down the Unit 1, Unit 2, and Unit 3 SFP areas to determine if appropriate controls were applied to materials and equipment stored in the pools and reactor cavity. The inspectors also reviewed the inventory of items stored in the pools. Controls and their implementation for LHRAs and for storage of irradiated material within the SFPs were reviewed and discussed in detail.
The inspectors evaluated implementation and effectiveness of licensee controls for both airborne and external radiation exposures. The inspectors reviewed and discussed selected whole-body count analyses conducted between February 8, 2008, and April 1, 2008, to evaluate implementation and effectiveness of personnel monitoring and administrative and physical controls including air sampling, barrier integrity, engineering controls, and postings for tasks having the potential for individual worker internal exposures to exceed 30 millirem committed effective dose equivalent. As Low As Reasonably Achievable (ALARA) evaluations for ongoing U3C13 activities were reviewed and discussed. Effectiveness of external radiation exposure controls were evaluated through review and discussion of individual worker dose as measured by DRD from February 1, 2007, to February 29, 2008, for select tasks. Radiation protection activities were evaluated against UFSAR, TS, and 10 CFR Parts 19 and 20 requirements. Specific assessment criteria included 10 CFR 19.12; 10 CFR 20, Subparts B, C, F, G, H, and J; TS Sections 5.4, Procedures and 5.7, High Radiation Area; and approved licensee procedures. Licensee guidance documents, records, and data reviewed within this inspection area are listed in Section 2OS1 and
4OA1 of the report Attachment.
Problem Identification and Resolution: The inspectors reviewed and assessed selected PER documents associated with access control to radiologically significant areas. The inspectors evaluated the licensee=s ability to identify, characterize, prioritize, and resolve the identified issues in accordance with procedure SPP-3.1, Corrective Action Program, Rev. 13. In addition, the inspectors reviewed self-assessments conducted related to access controls. Specific CAP documents associated with access control issues, personnel radiation monitoring, and personnel exposure events reviewed and evaluated during inspection of this program area are identified in Sections 2OS1 and
4OA1 of the report Attachment.
The inspectors completed the 21 required line-item samples described in Inspection Procedure (IP) 71121.01.
b. Findings
Introduction:
A Green, self-revealing non-cited violation (NCV) of TS 5.7.1 was identified for failure to conspicuously post, barricade, and control access to an HRA with dose rates not exceeding 1.0 rem per hour at 30 cm from the source.
Description:
On June 13, 2007, three workers were performing leak inspections in the Unit 1 moisture separator room when Operations raised reactor power from 23 percent RTP to 34 percent RTP. This power ascension caused radiation levels in the Unit 1 moisture separator room to increase from radiation area conditions to HRA conditions, with general area dose rates of approximately 150 mrem/hr. The controlling procedure for reactor startup, 1-GOI-100-1A, step 103.7, included a sign-off for radiation control (Radcon) to ensure appropriate HRA controls and postings were in place prior to exceeding 25 percent RTP. This procedure step was the corrective action from a previous similar event on Unit 3 which occurred on March 23, 2006. Radcon was notified, but the step was not signed-off prior to Operations personnel raising reactor power above 25 percent RTP.
The three workers received electronic dosimeter dose rate alarms of 140 mrem/hr, 212 mrem/hr, and 215 mrem/hr, which exceeded the dose rate setpoint of 50 mrem/hr. The workers were on a RWP that did not allow access to HRAs and had been briefed on radiological conditions that would be present with the reactor at 25 percent RTP. Upon identification of the change in radiological conditions, Radcon staff immediately posted and controlled the work area as an HRA.
Analysis:
The failure to post, barricade, and control an HRA is a performance deficiency. This finding is more than minor because it is associated with the Occupational Radiation Safety cornerstone attribute of exposure control and it affected the associated cornerstone objective because the failure to post, barricade, and control access to a HRA did not ensure the adequate protection of worker health and safety from exposure to radiation. The finding was evaluated using the Occupational Radiation Safety Significance Determination Process (SDP), and was determined to be of very low safety significance (Green) because the failure to post, barricade, and control the room did not pose a substantial potential for overexposure and did not affect the licensee's ability to assess doses. Dose could be assessed because the involved individuals were monitored for exposures from external radiation fields using alarming electronic dosimeters.
The cause of this finding is directly related to the work activity coordination cross-cutting aspect in the work control component of the Human Performance cross-cutting area because operations and health physicists personnel failed to effectively communicate and coordinate the activities associated with the power increase (H.3(b)).
Enforcement:
Technical Specification 5.7.1 required that HRAs with dose rates not exceeding 1.0 rem per hour at 30 centimeters from the radiation source shall have each entryway barricaded and conspicuously posted as an HRA. In addition, access to such areas shall be controlled by a RWP that includes specification of radiation dose rates in the immediate area. Contrary to the above, on June 13, 2007, the licensee failed to barricade, conspicuously post, and control an HRA with an RWP when Operations personnel raised reactor power from 25 percent RTP to approximately 34 percent RTP while workers were in the Unit 1 turbine building moisture separator room.
The finding was documented in the licensee's CAP as PER 126211. Because this violation was of very low safety significance and was entered into the licensee's CAP, it is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 50-259/2008003-01, Failure to Conspicuously Post, Barricade, and Control Access to a High Radiation Area During Power Ascension.
2OS3 Radiation Monitoring Instrumentation and Protective Equipment
a. Inspection Scope
Radiation Monitoring Instrumentation: During tours of the Units 1, 2, and 3 reactor buildings and turbine buildings, the inspectors observed installed radiation detection equipment including the following instrument types: area radiation monitors (ARMs), continuous air monitors, personnel contamination monitors (PCMs), portal monitors, and components of the Post-Accident Sampling System (PASS). The inspectors observed the physical location of the components, noted the material condition, and compared sensitivity ranges with UFSAR requirements.
In addition to equipment walk-downs, the inspectors observed functional checks and alarm setpoint testing of various fixed and portable detection instruments. These observations included: source checks of portable ion chambers and G-M survey meters using a Shepherd calibrator, source check of a neutron rem ball, source checks of PCMs and portal monitors at the Radiologically Controlled Area exit, and response checks for portable instruments being checked out for use. In addition, the response of the PCMs and portal monitors to a 5000 dpm plant mix smear was observed. The most recent 10 CFR Part 61 analysis for dry active waste was reviewed to determine if calibration and check sources are representative of the plant source term.
The inspectors reviewed the last two calibration records for selected PCMs, portal monitors, ARMs, and continuous air monitors (CAMs). Calibration stickers on portable survey instruments were noted during inspection of storage areas for Aready-to-use@ equipment. Records of quality assurance checks for the whole body counter were also reviewed. Operability and reliability of selected radiation detection instruments were reviewed against details documented in the following: 10 CFR Part 20; NUREG-0737, Clarification of TMI Action Plan Requirements; TS Section 3; UFSAR Chapter 12; and applicable licensee procedures. Documents reviewed during the inspection are listed in Sections 2OS3 and 2PS3 of the report Attachment.
Self-Contained Breathing Apparatus (SCBA) and Protective Equipment: Selected SCBA units staged for emergency use in the Units 1 and 2 and Unit 3 control rooms and other locations were inspected for material condition, breathing air cylinder pressure, and number of units available. The inspectors also reviewed maintenance records for selected SCBA units for the past five years and certification records associated with supplied air quality.
Qualifications for individuals responsible for testing and repairing SCBA vital components were evaluated through review of training records. In addition, control room operators were interviewed to determine their knowledge of available SCBA equipment locations, including corrective lens inserts if needed, and their training on bottle change-out during a period of extended SCBA use. Respirator qualification records were reviewed for several control room operators.
Licensee activities associated with maintenance and use of respiratory protection equipment were reviewed against 10 CFR Part 20; Regulatory Guide (RG) 8.15, Acceptable Programs for Respiratory Protection; and applicable licensee procedures. Documents reviewed during the inspection are listed in Section 2OS3 of the report
.
Problem Identification and Resolution: Selected licensee PERs associated with instrumentation and protective equipment were reviewed and assessed. The inspectors evaluated the licensee=s ability to identify, characterize, prioritize, and resolve the identified issues in accordance with procedure SPP-3.1, Corrective Action Program. The inspectors also evaluated the scope of the licensee's internal audit program and reviewed recent assessment results. Documents reviewed are listed in Section 2OS3 of the report Attachment.
The inspectors completed 9 of the 9 required line-item samples detailed in IP 71121.03.
b. Findings
No findings of significance were identified. 2PS1 Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems
a. Inspection Scope
Effluent Monitoring and Radwaste Equipment: During inspector walk-downs, accessible sections of the liquid and gaseous radioactive waste (radwaste) and effluent systems were assessed for material condition and conformance with system design diagrams. The inspection included floor drain tanks, liquid waste system piping, the Liquid Radwaste Effluent Monitor (RM-90-130), Turbine Building Exhaust Monitors (RM-90-249/251), Reactor Building Exhaust Monitor (RM-90-250), Radwaste Building Vent Monitor (RM-90-252), the Main Stack Monitors (RM-90-147/148), and associated airborne effluent sample lines. The inspectors interviewed licensee staff regarding radwaste equipment configuration and effluent monitor operation.
The inspectors reviewed performance records and calibration results for selected radiation monitors and flowmeters. Recent surveillance test results for the main stack air treatment system were also reviewed. The inspectors evaluated out-of-service effluent monitors and compensatory action data for the period February 2006 - May 2008. In addition, isokinetic sample line flow rates, line-loss calculations, and ventilation flow rates for the turbine building and reactor buildings were reviewed and discussed with chemistry staff to evaluate the adequacy of airborne effluent sampling.
Installed configuration, material condition, operability, and reliability of selected effluent sampling and monitoring equipment were reviewed against details documented in the following: 10 CFR Part 20; RG 1.21, Measuring, Evaluating and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials In Liquid and Gaseous Effluents from Light-Water Cooled Nuclear Power Plants; American Nuclear Standards Institute (ANSI)-N13.1-1969, Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities; TS Section 5; the Offsite Dose Calculation Manual (ODCM); and UFSAR, Chapter 7. Documents reviewed during the inspection are listed in Section 2PS1 of the report Attachment.
Effluent Release Processing and Quality Control Activities:The inspectors reviewed selected procedures for effluent sampling, processing, and release. Recent liquid and gaseous release permits were reviewed against ODCM specifications for pre-release sampling, effluent monitor setpoints, and projected doses to the public. The inspectors also reviewed the 2006 and 2007 radioactive effluent release reports to evaluate annual doses to the public and reviewed changes to the ODCM. The inspectors directly observed the weekly collection of airborne effluent samples from the main stack. Chemistry technician proficiency in collecting, processing, and counting the samples, as well as, preparing the applicable release permits was evaluated.
Quality Control (QC) activities regarding gamma spectroscopy and beta-emitter detection were discussed with count room technicians and Chemistry supervision. The inspectors reviewed daily QC data logs for selected gamma spectroscopy and liquid scintillation equipment and reviewed licensee procedural guidance for count room QC. In addition, results of the 2006 and 2007 radiochemistry cross-check program were reviewed. Observed task evolutions, count room activities, and offsite dose results were evaluated against details in the following: 10 CFR Part 20, Appendix I to 10 CFR Part 50; ODCM; RG 1.21; RG 4.15, Quality Assurance for Radiological Monitoring Programs (Normal Operations) - Effluent Streams and the Environment; and TS Section 5. Procedures and records reviewed during the inspection are listed in Section 2PS1 of the report Attachment. Groundwater Monitoring: The inspectors discussed current and future programs for onsite groundwater monitoring with licensee staff, including number and placement of monitoring wells and identification of plant systems with the most potential for contaminated leakage. The inspectors also reviewed procedural guidance for identifying and assessing onsite spills and leaks of contaminated fluids. In addition, the inspectors reviewed records of historical contaminated spills retained for decommissioning purposes as required by 10 CFR Part 50.75(g). The site had a series of wells that were installed as part of the pre-operational monitoring program. Of these wells, well number 6 was sampled routinely by grab sampling until the late 1970s at which time an automatic composite sampler was installed. In 1980-1981 eleven groundwater monitoring wells were installed for the Low Level Radioactive Waste disposal facility. TVA added six regional monitoring wells circa 1984 around the site. In 2000 three additional wells were added. In 2006 as part of a site hydrology study 34 geoprobe wells were installed. Most of these wells have been routinely sampled for tritium, the results have been used to narrow down the number of wells that need to be sampled, and the frequency of sampling is being reduced.
Analyses are performed for tritium and, for selected samples, hard-to-detect radionuclides. To date, tritium has been the only radionuclide identified in the well samples. One of the wells shows slightly elevated levels of tritium (approximately 4325 picocuries per liter (pCi/L)) due to historical spills and leakage. No levels exceeding the EPA drinking water limit of 20,000 pCi/L (corresponding to 4 millirem per year to a member of the public) have been identified in the onsite or offsite environs. Problem Identification and Resolution: Selected PERs associated with effluent release activities were reviewed and assessed. The inspectors evaluated the licensee's ability to identify, characterize, prioritize, and resolve selected issues in accordance with procedure SPP-3.1, Corrective Action Program. The inspectors also evaluated the scope of the licensee's internal audit program and reviewed recent assessment results. Reviewed documents are listed in Section 2PS1 of the report Attachment. The inspectors completed 3 of the 3 required line-item samples for IP 71122.01.
b. Findings

a. Inspection Scope
REMP Implementation: Inspectors reviewed and discussed with licensee representatives the results published in the Browns Ferry Annual Radiological Environmental Operating report for 2006 and 2007. The inspectors observed the collection and preparation of weekly particulate and radioiodine samples by licensee personnel and assessed material condition of four air-sampling stations along with the collocated thermoluminescent dosimeters (TLDs) to evaluate procedural compliance. The inspectors assessed the calibration status of each air-sampling pump. The inspectors also verified the placement of collection station locations against the sectors specified in the ODCM using a handheld global positioning system (GPS). The inspectors discussed with licensee representatives the procedures, methods, and equipment used to perform vegetation and sediment sampling. The inspectors reviewed and discussed with licensee representatives the procedures used to calibrate and determine the lower limit of detection (LLD) for environmental sample gamma spectroscopy analysis. REMP guidance, implementation, and results were reviewed against ODCM guidance and applicable procedures listed in Section 2PS3 of the report Attachment. Meteorological Monitoring Program: The inspectors reviewed the operability of the meteorological monitoring equipment and operator access to meteorological data. Current meteorological monitoring equipment performance, calibration and data recovery were reviewed. The inspectors interviewed licensee technicians responsible for equipment maintenance and surveillance concerning equipment performance, reliability, and routine inspections. Inspectors verified the availability of meteorological data on the plant computers. Meteorological instrument operation, calibration, and maintenance were reviewed against FSAR, Chapter 2; NRC Safety Guide 23, Onsite Meteorological Programs-1972; and applicable licensee procedures. Section 2PS3 of the report Attachment lists the documents reviewed. Unrestricted Release of Materials from the Radiologically Controlled Area (RCA): Radiation protection activities associated with radioactive material control and the unconditional release of materials from the RCA were reviewed and evaluated. The inspectors observed surveys of personnel and material exiting the RCA. The inspectors reviewed calibration records for three small article monitors. Types of sources used for checks and minimum detectable activities were discussed with an instrument technician. Additional efforts taken to reduce the background radiation and therefore increase the sensitivity of the monitors were discussed with health physics technicians, their supervisors and the Radiation Protection Manager.
The inspectors verified that radiation detection sensitivities were consistent with NRC guidance in IE Circular 81-07 and IE Information Notice 85-92. Section 2PS3 of the report Attachment lists the documents reviewed. Problem Identification and Resolution: Licensee CAP issues associated with environmental monitoring, meteorological monitoring, and release of materials were reviewed and discussed with cognizant licensee representatives. The inspectors assessed the licensee's ability to identify, characterize, prioritize, and resolve the identified issues in accordance with licensee procedure SPP-3.1, Corrective Action Program. Section 2PS3 of the report attachment lists the documents reviewed. The inspectors completed 10 of 10 required line-item samples for IP 71122.03.
b. Findings
Introduction:
A Green self-revealing NCV of 10 CFR 20.1801 was identified for failure to secure stored radioactive material from unauthorized removal.
Description:
On August 14, 2007, a shipment of "clean" scrap metal from Browns Ferry alarmed the truck monitor at a vendor recycling facility. Using a hand-held survey instrument, the vendor identified the contaminated item to be a small (4 oz) metal can containing pipe threading compound. Upon arrival at the site, licensee personnel retrieved the item and performed radiation surveys as necessary. Surveys determined the contaminated can read 6000 counts per minute on contact with a frisker, and 0.5 milliroentgen per hour (mR/hr) on contact and 0.1 mR/hr at 30 centimeters with an ion chamber. No other items contaminated with licensed material were identified. The licensee initiated a "B" level PER, 128870, to review this event and evaluate the root and common causes for this event and previous similar events. In developing a timeline for the event, it was determined that the pipe threading compound was received by the licensee on May 24, 2005; became contaminated during use sometime after that date; was removed from a contamination zone; was removed from the RCA; and inappropriately discarded into a scrap metal bin located at the low-level modifications facility sometime between July 24, 2007 and August 14, 2007. There was no way to identify the specific use, time of use, or individual(s) who used/discarded the particular can in question. Although unable to determine how this specific item was released from the RCA, the barrier analysis performed by the root cause analysis team identified a number of weak barriers and a failed barrier. The root cause was determined to be that processes and procedures governing control and transportation of potentially contaminated materials between RCAs and non-RCAs were not robust enough. The root cause team also concluded that the processes and controls for radioactive material control (including physical barriers) were not adequate. Self-assessment BFN-RP-07-003 of the radioactive material control program, completed shortly after this event, found that PER corrective actions generated due to plant events and previous self-assessments had been ineffective in resolving long standing radioactive material control problems. Based on discussion of PER 128870, self-assessment BFN-RP-003, and the radioactive material control program with cognizant licensee personnel, the inspectors learned that previous evaluations and self-assessments/audits had failed to thoroughly evaluate and identify all of the weaknesses in the radioactive material control program.
Analysis:
The failure to secure radioactive material from unauthorized removal is a performance deficiency. This finding is more than minor because it is associated with the Public Radiation Safety cornerstone attribute of program and process and it affected the associated cornerstone objective because the failure to secure stored radioactive material from removal did not ensure the adequate protection of public health and safety from exposure to radiation in that contaminated material was inappropriate released to the public domain. The finding was evaluated using the Public Radiation Safety SDP, and was determined to be of very low safety significance (Green) because the failure to secure radioactive material (contaminated can containing pipe threading compound) from removal was a finding in the radioactive material control program that did not result in a public exposure exceeding 5 mrem.
The cause of this finding is related to the evaluation of identified problems cross-cutting aspect in the corrective action component of the Problem Identification and Resolution cross-cutting area because evaluations performed by the licensee subsequent to previous radioactive material control events had failed to thoroughly evaluate and identify the weaknesses in the radioactive material control program. P.1(c)
Enforcement:
10 CFR 20.1801 requires that the licensee secure licensed materials stored in controlled or unrestricted areas from unauthorized removal or access.
Contrary to the above, the licensee failed to secure licensed material from unauthorized removal in that a can of pipe threading compound that was contaminated with licensed material was identified on August 14, 2007 at a vendor recycling facility by a truck monitor.
The finding was documented in the licensee's CAP as PER 128870. Because this violation was of very low safety significance and was entered into the licensee's CAP, it is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 50-259, 260, 296/2008003-02, Failure to Secure Stored Radioactive Material from Unauthorized Removal.

.2 Cornerstone:
Occupational Radiation Safety Occupational Exposure Control Effectiveness
a. Inspection Scope
The inspectors sampled licensee data for the PI listed below. To verify the accuracy of the PI data reported during the period reviewed, PI definitions and guidance contained in NEI 99-02 was used to verify the basis for each data element. The inspectors reviewed results from February 2007 through February 2008. For this period, the inspectors reviewed electronic dosimeter alarm logs and assessed CAP records to determine whether HRA, very HRA, or unintended radiation exposures had occurred. The inspectors also reviewed licensee procedural guidance for collecting and documenting PI data. In addition, the inspectors reviewed selected personnel contamination event data and internal dose assessment results. Report Section 2OS1 contains additional details regarding the inspection of controls for exposure significant areas. Documents reviewed are listed in Sections 2OS1 and
4OA1 of the report Attachment.

b. Findings
No findings of significance were identified.
.3 Cornerstone: Public Radiation Safety
Radiological Control Effluent Release Occurrences The inspectors reviewed the Radiological Control Effluent Release Occurrences PI results of Units 1, 2, and 3 for the Public Radiation Safety Cornerstone from April 2007 through April 2008. For this period, the inspectors reviewed cumulative and projected doses to the public and selected PERs related to Radiological Effluent Technical Specifications (RETS)/ODCM issues. The inspectors also reviewed licensee procedural guidance for collecting and documenting PI data. Licensee records were reviewed against guidance contained in NEI 99-02,and the NEI Frequently Asked Questions (FAQ) list. Documents reviewed are listed in section
4OA1 of the report Attachment.
b. Findings
No findings of significance were identified.
4OA2 Identification and Resolution of Problems
.1 Routine Review of Problem Evaluation Reports
a. Inspection Scope
The inspectors performed a daily screening of all PERs entered into the licensee's CAP. The inspectors followed NRC Inspection Procedure 71152, Identification and Resolution of Problems, in order to help identify repetitive equipment failures or specific human performance issues for follow-up.
b. Findings and Observations
No findings of significance were identified.
.2 Semiannual Trend Review
a. Inspection Scope
As required by Inspection Procedure 71152, the inspectors performed a review of the licensee's CAP and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors' review included the results from daily screening of individual PERs (see Section 4OA2.1 above), licensee trend reports and trending efforts, and independent searches of the PER database and WO history. The review also included issues, documented outside the normal CAP, in system health reports, corrective maintenance WOs, component status reports, site monthly meeting reports and maintenance rule assessments. The inspectors' review nominally considered the six-month period of January 2008 through June 2008, although some PER database and WO searches expanded beyond these dates. Furthermore, the inspectors verified that adverse or negative trends identified in the licensee's PERs, periodic reports and trending efforts were entered into the CAP. In particular, the inspectors reviewed the licensee's Integrated Trend Review (ITR) program and the implementation of the program. Inspectors also interviewed the appropriate licensee management.
b. Findings and Observations
No findings of significance were identified.
As documented in the Brown's Ferry Turn-Around Plan, trend reviews were conducted each quarter. The intent of this review was to identify the top organizational issues, both at the department and site level, and to report on the progress being made to resolve them. The inspectors determined that the licensee's trending program, in general, has shown improvement from previous inspection reports. The ITR Meeting was scheduled in the plan of the day (POD) well in advance and departments were actively participating in the process. It was also noted that a new Performance Improvement Department Procedure (PIDP-11) had been issued during this period, to provide additional guidance on conducting trending.
The inspectors noted two observations with the trending program. First, some departmental trends that were continuing from previous ITRs relied on existing PERs without conducting a thorough evaluation to determine if the existing PERs were adequate to correct the problem. Secondly, some trend PERs were not assigned priorities and/or causal analysis levels that were effective in addressing the adverse trend. These observations are described in greater detail below:
- Some trends were identified during the ITR process as continuing from previous reports with reliance on existing PERs to reverse the trend. It was not apparent that adequate evaluation was being conducted to ensure that the existing PER corrective actions were being effective, that these actions were timely enough or that criteria was being established where additional actions were needed (i.e., when an additional PER would be required).
- Some trend PERs were not assigned priorities and/or causal analysis levels that were effective in addressing the adverse trend. For example several trend PERs were written on the work management process (PERs 138297, 140600, 140738, and 145505) which were all assigned as Level C with no causal analysis required. Subsequently, a Level A PER was initiated on the work management process based on Nuclear Safety Review Board review. PERs categorized as Level C without any causal evaluation included Engineering not using department performance indicators or department clock resets to monitor performance; inadequate oversight of Engineering products by management; and, inadequate use of self-assessments to improve performance. The inspectors also conducted an independent review to identify potential negative trends. This review noted that several parameters were experiencing negative trends including human performance, industrial safety, corrective/elective maintenance backlogs, deferred/late preventive maintenances (PMs), PMs in grace period, cause analysis quality and PER backlog. The licensee acknowledged these trends and has put action plans in place to address them.
.3 Focused Annual Sample Review - Browns Ferry's Organizational Effectiveness
a. Inspection Scope
The inspectors reviewed the specific corrective actions associated with B level PER 132649, Fundamentals of Engineering, in accordance with the guidelines and requirements of SPP 3.1, Corrective Action Program. This PER originally dealt with a Self-Assessment Area for Improvement (AFI) in Engineering on shortfalls in management escalation of important issues, monitoring of training effectiveness and addressing staffing shortfalls which have resulted in a plant trip, program and training ineffectiveness, and staffing shortfalls. The PER problem description was subsequently changed to address the broader issue of Browns Ferry's Organizational Effectiveness at identifying and correcting performance shortfalls over the past 24 months associated with the numerous Unit 1, 2 and 3 reactor scrams, and the 2007 Mid-cycle Self-Assessment.
b. Findings and Observations
No findings of significance were identified.
Seven other PERs were closed to PER 132649. However, some of the issues in these seven PERs were not specifically addressed by PER 132649, nor were previous similar events for each of the conditions evaluated. Only four of the seven closed PERs were referenced in PER 132649. In particular, the original condition described in PER 132649, on Engineering Department training effectiveness and staffing shortfalls, was not addressed by the broader PER. Additionally, some of the other PER conditions closed to PER 132649 that were not directly addressed, included on-line maintenance risk management (PER 133019), weaknesses in the work control process (PER 134677), poor industrial safety performance (PER 132659) and management of changes in the work force (PER 132660).
PER132651 was written as a result of the 2007 mid-cycle self-assessment and dealt with repeat events caused by ineffective cause analysis and corrective action, and with the timeliness of corrective action plans and actions. [Note, it was one of the PERs specifically addressed and referenced by PER 132649.] Numerous previous PERs written during the last two years have identified weaknesses with the CAP. However no rigorous evaluation was conducted on why actions from these PERs were ineffective in improving the program. The licensee initiated PER 147684 to review this condition and implement appropriate corrective actions.
Several actions were extended without a formal extension request. Action 21 of PER 132649 was originally due January 31, 2008, and was formally extended to February 29, 2008. However, review of the PER on March 5 showed the due date as March 7, 2008 and the action currently shows a due date of June 17, 2008. No extension request was submitted for these changes. Additional examples of due date extensions without extension requests were actions 22, 23, 24 and 25. The licensee initiated PER 147685 to review this condition and implement appropriate corrective actions. Two actions in PER 132649 were not properly designated. One corrective action to prevent recurrence (CATPR), Action 40, was to re-perform the employee survey to identify changes in perceptions and to use the new station performance metrics to evaluate progress toward industry performance expectations. This action was an evaluation of the effectiveness of the other corrective actions and was not a true CATPR. The other CATPR, Action 41, was to develop a turn around plan. The development of the turn around plan, in of itself was not a CATPR. As a result, the turn around plan actions could be extended, changed or deleted without additional Corrective Action Review Board (CARB) review which was the licensee's practice for a CATPR. Thus, specific actions in the turn around plan which might be actions to prevent recurrence, i.e., CATPRs, could be extended, changed or deleted without their normal CARB review. The licensee initiated PER 147686 to review these conditions and implement appropriate actions. One of the actions (Action 29) in PER 132649, was to issue a PER on any CAP metric (i.e., performance indicator) that was red for three months. This action was closed on January 31, 2008. To date, the only red CAP indicators that have had PERs written were the indicators for A and B PERs greater than 1 year old and the overall backlog of open PERs. Other CAP indicators that were currently red include Apparent Cause Evaluation quality and percentage of effectiveness reviews that determine actions have been effective. No PERs have been submitted on these other red CAP PIs. The licensee initiated PER 147687 to review this condition and implement appropriate corrective actions.
.4 Focused Annual Sample Review - Turnaround Plan Equipment Reliability
a. Inspection Scope
In February 2008, the licensee instituted the Turnaround Plan to Excellence for the Browns Ferry Nuclear Plant. One of the major focus areas of this Plan was "Equipment Reliability." In the area of Equipment Reliability, the inspectors specifically reviewed the licensee's corrective action plans to address the principal aspects of "Top Equipment Priorities for System Health" and "Equipment Reliability Longterm Improvement." The inspectors also reviewed the most recent Plant Health Report and various System Health Report Cards (e.g., RHRSW/EECW), and attended several Plant Health Meetings. As part of these plant health and system reviews, the inspector reviewed the applicable program guidance of BP-254, Plant Health Committee and Conduct of Action Teams, and NEDP-12, System, Component and Program Health, Equipment Failure Trending. Furthermore, the inspectors interviewed responsible system engineers, Engineering Department management, Outage and Non-outage Work Control management, Corporate Systems and Component management, and Turnaround Plan management.
b. Findings and Observations
No findings of significance were identified.
The inspectors identified a number of observations which are described below:
- All the Top Equipment Priorities for System Health action plans were complete except for action #9 and #10. Action #9 for providing site wide communication on the top equipment issues was overdue since June 13, 2008. However, communication action plans were in progress. Action #10 for executing the actual work to resolve the numerous top equipment issues was the responsibility of the appropriate department managers (e.g., Engineering, Maintenance, Modifications, etc.) in accordance with specific schedules. The "First Round" of top equipment issues coded as T/A by the Turnaround Plan were scheduled to be implemented during the next two refueling outages (U1C7 and U2C15) and next two fiscal years.
Essentially all of the outage related T/A top equipment issues were appropriately scheduled for the next Unit 1 and 2 refueling outages. However, only about half of the non-outage related T/A top equipment issues had definitive schedules for executing work within this and the next fiscal year. Of these unscheduled non-outage T/A equipment issues, almost all were associated with EDG reliability improvement. Due to the number and complexity of EDG reliability issues, the licensee just recently in July assigned a project manager to specifically coordinate execution of these issues
- Only about half of the Equipment Reliability Longterm Improvement actions plans were complete. Actions #1, 2, 5, 10 and 11 were still incomplete, some of which were overdue or needed significant revision. The first two action plans involved establishing a Plant Health Subcommittee by June 4, 2008, to accelerate System Health scrubs and assist the Plant Health Committee by identifying and escalating important issues. However, this subcommittee was never established. The licensee intends on revising/eliminating these actions. The development of long range action plans for improving important systems and components was due July 18, 2008. However, little had been accomplished to date, and the licensee was planning to revise their action plan approach and schedule. Action #10 for extracting the identification of critical spare issues was overdue since June 3, 2008. This action was still in progress.
- The verification of EECW flow through RHR room coolers per SI-3.2.4, EECW Check Valve Test, and 0-TI-54, EECW System Operational Flush, only measured the combined EECW flow for both RHR pump room coolers in a division. This measurement was made at the common EECW discharge header while both RHR room coolers were aligned in parallel. The EECW flow rate for individual RHR pump room coolers was not being measured, evaluated or trended to ensure adequate EECW flow. The licensee initiated PER 148300 to address this issue.
- There was no integrated project plan or schedule for addressing the numerous RHRSW/EECW system equipment reliability issues (e.g., motor replacement, power cable replacement, pump shaft replacement, RHR Hx service water outlet valve and inlet check valve replacement/repair, 2B and 2D RHR Hx floating head replacement, RHRSW/EECW sump pump leakage, etc.) to ensure maximum optimization of system unavailability and reliability. To date, the B3 EECW and A2 RHRSW pumps have exceeded their Maintenance Rule unavailability performance criteria and been entered into MR (a)(1) status, and the B2 RHRSW pump was at 75% of its unavailability performance criteria. The 1B, 2B, and 2D RHR Hx's have already exceeded their unavailability performance criteria and were also in MR (a)(1) status. Currently, the licensee continues to rely on their routine work control and scheduling processes to balance reliability and unavailability of future work.
- The Browns Ferry Equipment Reliability Indicator (ERI) indices for Units 2 and 3 have not shown any sustained improvement over the past three and half years. The ERI index for Units 2 and 3 have remained within a band of 59 to 71 (out of 100) since 2006. In addition, the first Unit 1 ERI index since restart was reported as 68 for the first quarter of 2008. The overall ERI indices for Units 2 and 3, have been oscillating around the Yellow/White threshold of 65 since 2006. Although, the licensee did not initiate a comprehensive PER to address their ineffectiveness at generating sustained improvement in overall plant equipment reliability performance, they did initiate individual PERs to develop recovery plans for the specific ERI sub-indicators that had turned Red.
Furthermore, the licensee initiated PER 148702 to specifically improve the System Health/Plant Health Program.
- The number of systems identified by the system health process as Red and Yellow had been at 38 since September 2007. Following the most recent Unit 3 refueling outage (i.e., U3C13), the number of Red and Yellow systems improved to 34. However, the Plant Health Report issued in July indicated the number had increased back to 36 with a significant increase in the number of red systems from four to seven. A significant contributor to the persistent number of Red and Yellow systems was the backlog and increased age of S2 coded work orders [S2 code is for system issues that could lead to MR functional failure or exceed unavailability criteria; are needed to resolve a Red or Yellow condition; represent a degraded/non-conforming condition; have a significant impact on reactivity management, etc.]. The number of S2 coded work orders has increased from 330 to 375 since March 2008. The excessive backlog of these higher priority WO's and the station's difficulty in working them off was a significant contributor to the persistently high number of important systems that need system health improvement. The licensee was aware of these program issues and had initiated PER 148700 to address the impact of large backlogs on equipment reliability and the lack of effectively managing priority work.
- The "Road to Green" for almost all Red and Yellow systems in the Plant Health report were flagged as having inadequate corrective action plans to meet their goal of improving system health color by September 30, 2008. The licensee has not developed revised goals or action plans to improve their "Road to Green" performance. In addition, approximately one fourth of the 38 Red and Yellow systems had no specific date for a projected return to either White or Green. For those Red and Yellow systems that did have projected dates, these dates did not reflect the future impact of existing S2 WO's that were continuing to age and would exceed the 24 and 48 week thresholds. The licensee was aware of these program issues.
- As part of the Turnaround Plan, it was recognized that very few systems have long range improvement plans. PER 132638 had been initiated previously in October 2007 to address the lack of ownership and accountability for long range planning and asset management. Equipment Reliability Longterm Improvement is an integral part of the Turnaround Plan. However, the corrective actions of PER 132638 had not been updated to reflect subsequent changes by Corporate and site Project management in their proposed and ongoing actions.
- The last critical component failure trend report was completed in July 2007. However, this report did not initiate any PERs for adverse trends. Although, individual PERs were routinely issued for each critical component failure, no thresholds were established for initiating PERs to address potential adverse trends. There were several systems (e.g., Radiation Monitoring, 480V Reactor Motor Operated Valve Boards) with numerous critical component failures that might have warranted further evaluation as an adverse trend. The licensee intended to address these issues in the next critical component trend report due this year.
4OA5 Other Activities
.1 (Closed) Unresolved Item (URI) 05000259, 260, 296/2007007-03, Degraded Flood Protection Doors for the Intake Cooling Structure
During the component design bases inspection conducted November 13, 2007, to December 14, 2007, an URI was identified concerning inadequate maintenance of watertight protection doors. This URI was initially discussed in NRC Inspection Report 05000259, 260, 296/2007007 dated January 25, 2008.
Introduction:
The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for the licensee's failure to identify and correct deficiencies in watertight doors that protect safety-related pumps from external flooding.
Description:
The RHRSW and EECW pumps are housed in the A, B, C, and D rooms of the intake cooling structure. Each room is protected from external flooding by a watertight door. UFSAR Section 12.2.7.1.2 states, in part, that the doors protect the pumps from the probable maximum flood (PMF). The UFSAR also specifies that the watertight doors are to be inspected periodically. The licensee uses Maintenance Procedure, MPI-0-260-DRS001, Inspection and Maintenance of Doors, Section 7.8, "Chalk Test and Seal Adjustment - Watertight/Flood Doors" on a quarterly basis for maintaining the functionality of the doors.
On November 20, 2007, the inspection team observed closed watertight doors with gaps up to 1/2 inch between the door seal and door frame. The licensee's subsequent evaluation determined that three of the four doors would not provide adequate protection for the RHRSW and EECW pumps during a flood. The licensee initiated work orders to repair the doors and PERs 133899 and 134346. The inspectors reviewed WO 07-717987-000 (completed September 26, 2007) which was the most recently completed quarterly inspection of the doors. The WO directed the performance of quarterly door inspections in accordance with Section 7.8 of Procedure MPI-0-260-DRS001. The work order documented all four doors were functional, although Door D had missing components (gear covers and two dog arms). The inspectors determined that based on the severity of the degradation in the door seals and the short duration between the September 2007 inspection and the discovery of the conditions on November 20, 2007, the degradation had existed at the time of the September 2007 inspection. Thus, the inspectors concluded that the inspection performed in September 2007 was inadequate.
Analysis:
Brown Ferry's failure to identify and correct the degraded watertight doors that protect safety-related pumps during an external flooding event is a performance deficiency. This finding is more than minor because it affects the External Factors (Flood Hazard) attribute of the Mitigating Systems Cornerstone. It impacts the cornerstone objective of ensuring the availability, reliability, and operability of RHRSW and EECW pumps to perform their intended safety function during a design basis flooding event. In accordance with the SDP Phase 3 analysis was performed to determine the finding's significance because the finding involved the degradation of equipment designed to mitigate a flooding event and it was risk significant due to external initiating event core damage sequences. Using information from the licensee's river group concerning probability of flooding, input from the UFSAR describing the design basis flood, and records of discussions held before the Advisory Committee on Reactor Safeguards on October 9, 1985, a conservative estimate for the design basis flood was set to about E-3. Conditional Core Damage Probabilities (CCDPs) were calculated for cases where the B and D Rooms were flooded, and for the A, B, and D Rooms flooded. The initiating event frequency was multiplied by the CCDPs in sensitivity calculations, to obtain an idea of the risk using the bounding assumptions. The Core Damage Frequencies(CDFs) were assumed to be the same as the Large Early Release Frequencies, because the dominant sequences involved loss of containment heat removal at a Mark 1 BWR. The most limiting result for the change in CDF due to the condition was at the Green to White threshold. Because this was the upper bound and this evaluation contained a large degree of conservatisms, the CDF was determined to be below the Green to White threshold. Thus, the finding was determined to be of very low safety significance, Green, because of the low likelihood of the design basis flood.
The finding was directly related to the cross-cutting aspect of procedural compliance of the work control component of the cross-cutting area of Human Performance.
Mechanics were not complying with quarterly work orders and a maintenance procedure to assure functionally of the watertight doors (H.4(b)).
Enforcement:
10 CFR 50, Appendix B, Criterion XVI, Corrective Action, states, in part that measures shall be established to assure that conditions adverse to quality are promptly identified and corrected. Contrary to the above, conditions adverse to quality were not promptly identified and corrected, in that, gaps in the door seals for three doors which provide protection to safety-related pumps, were not identified during door inspections prior to their discovery by the NRC on November 20, 2007. Because this finding is of very low safety significance (Green) and because it was entered into the licensee's corrective action program as PER 133899 and 134346, this violation is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000259, 260 and 296/2008003-03, Failure to Identify and Correct Deficiencies in Degraded Flood Protection Doors.
.2 Quarterly Resident Inspector Observations of Security Personnel and Activities
a. Inspection Scope
During the inspection period, the inspectors conducted observations of security force personnel and activities to ensure that the activities were consistent with licensee security procedures and regulatory requirements relating to nuclear plant security.
These observations took place during both normal and off-normal plant working hours.
b. Findings
No findings of significance were identified.
.3 Independent Spent Fuel Storage Installation (ISFSI)
a. Inspection Scope
ISFSI Radiological Controls: 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 select casks, and reviewed gamma and neutron radiation surveys of the ISFSI facility performed by licensee personnel. Inspectors also compared the independent survey results to previous surveys and against procedural and TS limits. The inspectors evaluated implementation of radiological controls, including labeling and posting, and discussed controls with RP 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. ALARA planning for, and a self-assessment of, the most recent dry cask storage campaign were reviewed. Radiological control activities for ISFSI areas were evaluated against 10 CFR Part 20, 10 CFR Part 72, and TS details. Documents reviewed are listed in section
4OA5 of the report Attachment.
The inspectors completed the RP line-item sample activities specified in IP 60855.1.
b. Findings
No findings of significance were identified.
4OA6 Management Meetings
Exit Meeting Summary
On July 2, 2008, and the resident inspectors presented the integrated inspection results to Mr. Rusty West, and other members of his staff, who acknowledged the findings. During a conference call on July 17, 2008, the finding in Section 4OA5.2 was discussed with Mr. Steve Douglas and members of your staff. On August 4, 2008, the findings were re-exited with Mr. James Emens. The inspectors confirmed that proprietary information was not provided or examined during the inspection period.
