UNITED STATES NUCLEAR REGULATORY COMMISSION REGION II 245 PEACHTREE CENTER AVENUE NE, SUITE 1200 ATLANTA, GEORGIA 30303-1257 October 28, 2011 EA-11-245 Mr. Regis T. Repko Vice President Duke Energy Carolinas, LLC McGuire Nuclear Station MG01VP/12700 Hagers Ferry Road Huntersville, NC 28078

SUBJECT:

MCGUIRE NUCLEAR STATION - NRC INTEGRATED INSPECTION REPORT AND EXERCISE OF ENFORCEMENT DISCRETION - 05000369/2011004 AND 05000370/2011004

Dear Mr. Repko:

On September 30, 2011, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your McGuire Nuclear Station Units 1 and 2. The enclosed inspection report documents the inspection results, which were discussed on October 13, 2011, with you and other members of your staff.

The inspection examined activities conducted under your licenses as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your licenses. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

The enclosed inspection report documents one NRC-identified finding of very low safety significance (Green) which was determined to involve a violation of NRC requirements.

Additionally, one licensee-identified violation, which was determined to be of very low safety significance, is listed in this report. However, because of the very low safety significance and because they were entered into your corrective action program, the NRC is treating these violations as non-cited violations (NCVs) consistent with Section 2.3.2 of the NRC Enforcement Policy. If you contest any NCV in this report, you should provide a written response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington, D.C. 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the NRC Resident Inspector at McGuire. In addition, if you disagree with the characterization of any finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region II, and the NRC Resident Inspector at McGuire.

DEC 2 The enclosed inspection report also documents one noncompliance for which the NRC is exercising enforcement discretion. The noncompliance involved a failure to ensure that fire protection features were capable of limiting fire damage so that systems necessary to achieve and maintain cold shutdown could be repaired within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The NRC is not taking enforcement action for this noncompliance because it meets the criteria of the NRCs Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues (10 CFR 50.48). In this case, the NRC concluded that: (1) Duke Energy Carolinas, LLC, entered the noncompliance into its corrective action program and implemented appropriate compensatory measures; (2) the noncompliance was not associated with a finding that the reactor oversight process significance determination process would evaluate as Red, or it would not be categorized at Severity Level I; (3) it was not willful; and (4) Duke Energy Carolinas, LLC, submitted a letter before December 31, 2005, stating its intent to transition to 10 CFR 50.48(c),

which includes approaches in National Fire Protection Association Standard 805-2000 Edition.

The NRC will refrain from including the noncompliance in the Agency Action Matrix in accordance with NRC Inspection Manual Chapter 0305, Section 11.05.b, Violations in Specified Areas of Interest Qualifying for Enforcement Discretion.

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 NRCs document system (ADAMS). ADAMS is accessible from the NRC Website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/

SUMMARY

OF FINDINGS IR05000369/2011-004, IR05000370/2011-004; 7/1/2011 - 9/30/2011; McGuire Nuclear Station; Other Activities The report covered a three month period of inspection by two resident inspectors and nine region based inspectors. One Green finding, which was determined to involve a violation of NRC requirements, 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). Cross-cutting aspects are determined using IMC 0310, Components Within The Cross-Cutting Areas. Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process.

Cornerstone: Mitigating Systems

• Green. The inspectors identified a NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, for the failure to establish acceptance criteria to determine operability in surveillance procedures used to vent the decay heat removal (ND) system in Modes 5, 6, and No-Mode in preparation for Mode 6. The issue was entered into the licensees corrective action program as PIP M-11-04745 The licensees failure to establish adequate acceptance criteria for ND venting surveillance procedures PT/1/A/4200/036 and PT/2/A/4200/036 was a performance deficiency (PD).

The PD was determined to be more than minor because if left uncorrected, the failure to establish acceptance criteria for surveillance tests which establish the basis for the ND system operability in modes 5 and 6 would have the potential to lead to a more significant safety concern in that conditions which could impact system operability could remain undetected. In addition, the finding adversely affected the equipment performance attribute of the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.

Using IMC 0609, Appendix G, Shutdown Operations Significance Determination Process, Attachment 1, the finding was determined to be of very low safety significance (Green) because a quantitative assessment was not required based on the criteria in Attachment 1.

The finding had a cross-cutting aspect of implementation of operating experience in the Operating Experience component in the area of Problem Identification and Resolution because the licensee failed to implement operating experience from Generic Letter (GL) 2008-01 into station procedures P.2(b). (Section 4OA5.4)

One violation of very low safety significance (Green), which was identified by the licensee, has been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. This violation and corrective action tracking number are listed in Section 4OA7 of this report.

2. RADIATION SAFETY Cornerstones: Occupational Radiation Safety and Public Radiation Safety 2RS1 Radiological Hazard Assessment and Exposure Controls

a. Inspection Scope Hazard Assessment and Instructions to Workers: The inspectors observed labeling of radioactive material and postings for radiation areas, high radiation areas (HRAs), and contaminated areas established within the radiologically controlled area (RCA) of the Unit 1 and Unit 2 auxiliary buildings, and radioactive waste (radwaste) processing and storage locations. The inspectors independently measured radiation dose rates or observed licensee radiation surveys for selected RCA areas including the Independent Spent Fuel Storage Installation. The inspectors reviewed survey records for several plant areas including surveys for alpha emitters, hot particles, airborne radioactivity, gamma surveys with a range of dose rate gradients, and pre-job surveys for upcoming tasks. The inspectors also discussed changes to plant operations that could contribute to changing radiological conditions since the last inspection. The inspectors attended Enclosure

12 selected pre-job briefings and reviewed the radiation work permit (RWP) details to assess communication of radiological control requirements and current radiological conditions to workers.

Hazard Control and Work Practices: The inspectors evaluated access barrier effectiveness for selected locked high radiation area (LHRA) and very high radiation area (VHRA) locations. Changes to procedural guidance for LHRA and VHRA controls were discussed with health physics (HP) supervisors. Controls and their implementation for storage of irradiated material within the spent fuel pool were reviewed and discussed in detail. Established radiological controls (including airborne controls) were evaluated for selected tasks including fuel transfer cart maintenance and entry into LHRAs. In addition, licensee controls for areas where dose rates could change significantly as a result of refueling operations were reviewed and discussed.

Worker adherence to RWPs and HP technician (HPT) proficiency in providing job coverage was evaluated through direct observations and interviews with licensee staff.

Electronic dosimeter (ED) alarm set points and worker stay times were evaluated against area radiation survey results for fuel transfer cart maintenance. ED alarm logs were reviewed and worker response to dose and dose rate alarms was evaluated. For HRA tasks involving significant dose rates, (e.g. valve maintenance activities), the inspectors evaluated the use and placement of whole body and extremity dosimetry to monitor worker exposure.

Control of Radioactive Material: The inspectors observed surveys of material and personnel being released from the RCA using small article monitor, personnel contamination monitor, and portal monitor instruments. The inspectors reviewed the last two calibration records for selected release point survey instruments and discussed equipment sensitivity, alarm setpoints, and release program guidance with licensee staff.

The inspectors also reviewed records of leak tests on selected sealed sources and discussed nationally tracked source transactions with licensee staff.

Problem Identification and Resolution: PIPs associated with radiological hazard assessment and control were reviewed and assessed to evaluate the licensees ability to identify and resolve the issues. The inspectors also evaluated the scope of the licensees internal audit program and reviewed recent assessment results.

13 2RS5 Radiation Monitoring Instrumentation

a. Inspection Scope Radiation Monitoring Instrumentation: The inspectors observed installed radiation detection equipment during walk-downs of the auxiliary building and the RCA exit point including area radiation monitors (ARMs), liquid and gaseous effluent monitors, personnel contamination monitors (PCMs), small article monitors (SAMs), and portal monitors (PMs). The inspectors observed the physical location of the components and noted their material condition. The inspectors also observed source checks of various portable and fixed detection instruments, including ion chambers, telepoles, PCMs, SAMs, PMs, and a whole body counter (WBC). For the portable instruments, the inspectors observed the use of a high-range calibrator and discussed periodic output value testing with the licensee. The inspectors also observed the performance of a process monitor channel operational test. The inspectors reviewed calibration records and evaluated alarm setpoint values for PCMs, PMs, effluent monitors, an ARM, a SAM, and a WBC. This included a sampling of instruments used for post-accident monitoring such as a containment high-range radiation monitor and effluent monitors for noble gas and iodine. The radioactive source used to calibrate an effluent monitor was evaluated for traceability to national standards. Calibration stickers on portable survey instruments were noted during inspection of the storage area for ready-to-use equipment. The inspectors reviewed the most recent 10 CFR 61 analysis for dry active waste to determine if calibration and check sources are representative of the plant source term.

The inspectors also reviewed countroom calibration records for a gamma spectroscopy germanium detector and a liquid scintillation detector. The inspectors reviewed effectiveness and reliability of selected radiation detection instruments against details documented in 10 CFR 20; NUREG-0737, Clarification of TMI Action Plan Requirements; UFSAR Chapters 11 and 12; and applicable licensee procedures.

Problem Identification and Resolution: The inspectors reviewed selected PIPs in the area of radiological instrumentation to evaluate the licensees ability to identify and resolve the issues.

Documents reviewed are listed in the Attachment. The inspectors completed one sample.

b. Findings No findings were identified.

2RS6 Radioactive Gaseous and Liquid Effluent Treatment

a. Inspection Scope Event and Effluent Program Reviews: The inspectors reviewed the 2009 and 2010 Annual Radiological Effluent Release Report (ARERR) documents for consistency with the requirements in the Offsite Dose Calculation Manual (ODCM) and TS details.

Routine and abnormal effluent release results and reports, as applicable, were reviewed Enclosure

14 and discussed with responsible licensee representatives. Status of the radioactive gaseous and liquid effluent processing and monitoring equipment and activities, and changes thereto, as applicable, described in the UFSAR and current ODCM were discussed with responsible staff.

Walk-Downs and Observations: The inspectors walked-down selected components of the gaseous and liquid discharge systems to ascertain material condition, configuration and alignment. Walkdowns included visual inspections of 0EMF-49, Waste Liquid Radiation Monitor; 1EMF-35, Unit Vent Particulate Radiation Monitor; 1EMF-36, Unit Vent Gaseous Radiation Monitor; and 1EMF-37, Unit Vent Iodine Radiation Monitor. To the extent practical, the inspectors observed the material condition of abandoned in place liquid waste processing equipment for indications of degradation or leakage that could constitute a possible release pathway to the environment. The inspectors also observed the collection and analysis of a liquid effluent sample from the waste monitor tank (WMT).

Sampling and Analyses: The inspector observed the preparation of the samples from the WMT for counting, administrative processing, and implementation of the liquid effluent release permit. The inspector noted independent verification of the permit results and concurrent verification of equipment manipulations performed to allow the release. The results of the chemistry count rooms inter-laboratory comparison program were reviewed and discussed with the licensee.

Dose Calculations: The inspectors discussed recent changes in reported dose values relative to previous ARERR reporting periods with an emphasis placed on Carbon-14 radionuclide source term quantities and resultant doses. The inspectors reviewed and evaluated a waste gas decay tank (WGDT) release and a liquid effluent release. The evaluations included review and discussion of set point determinations and dose calculation summaries. Dose calculations associated with potential WGDT releases were reviewed and discussed in detail. Updated results for the most recent land use census data were evaluated against assumptions used to calculate offsite dose results.

In addition, the inspectors reviewed selected abnormal release data and resultant dose calculations for Calendar Years (CYs) 2009 and 2010.

Effluent process and monitoring activities were evaluated against details and requirements documented in the UFSAR Sections 11 and 12; Selected Licensee Commitment Section 16, TS Sections 5.4.1, 5.5, and 5.6; the ODCM; 10 CFR 20; 10 CFR 50, Appendix I; and approved licensee procedures. In addition, ODCM and UFSAR changes since the last onsite inspection were reviewed against the guidance in NUREG-1301 and Regulatory Guide (RG) 1.109, RG 1.21, and RG 4.1.

Ground Water Protection Implementation: The licensees implementation of the Industry Ground Water Protection Initiative was reviewed for changes since the last inspection.

Groundwater sampling results obtained since the last inspection were reviewed.

Licensee response, evaluation, and follow-up to spills and leaks since the last inspection were reviewed in detail.

Enclosure

15 Problem Identification and Resolution: The inspectors reviewed selected PIPs in the areas of effluent processing and groundwater protection to evaluate the licensees ability to identify, characterize, prioritize, and resolve the identified issues.

Documents reviewed are listed in the Attachment. The inspectors completed one sample.

b. Findings No findings were identified.

2RS7 Radiological Environmental Monitoring Program (REMP)

a. Inspection Scope REMP Status and Results: The inspectors reviewed and discussed recent and proposed changes applicable to Radiological Environmental and Meteorological Monitoring program activities detailed in the UFSAR, and ODCM. Environmental monitoring sample results presented in the Annual Radiological Environmental Operating Report (AREOR) documents issued for CYs 2009 and 2010 were reviewed and discussed. REMP vendor laboratory cross-check program results and select procedural guidance for collection, processing and analysis of airborne particulate and iodine, and broadleaf vegetation were reviewed and discussed with knowledgeable personnel. Detection level sensitivities as documented within the AREOR for selected environmental media analyzed by the offsite environmental laboratory were reviewed.

The AREOR environmental measurement results were reviewed for consistency with licensee ARERR data and evaluated for radionuclide concentration trends. Licensee actions for missed airborne monitoring samples were reviewed and discussed in detail.

Site Inspection: The inspectors observed and discussed implementation of selected REMP monitoring and sample collection activities for atmospheric particulates and iodine, and observed locations of direct radiation measurements, and broadleaf vegetation samples sites as specified in the current ODCM and applicable procedures.

The inspectors observed equipment material condition and evaluated operability, including a review of flow rates and total sample volume results for the weekly airborne particulate filter and iodine cartridge change-outs at seven atmospheric sampling stations. Justification for changing a site air monitoring station was reviewed against ODCM criteria. In addition, the inspectors discussed broadleaf vegetation and surface water sampling for selected ODCM locations. Monitoring and impact of licensee routine releases on offsite doses based on meteorological dispersion parameters and gardens locations identified in the most current land use census were reviewed in detail.

Material condition and placement of selected environmental thermo-luminescent dosimeters were observed. Actions for missed samples including compensatory measures and/or availability of replacement equipment were discussed with vendor technicians and knowledgeable licensee staff. In addition, sample pump calibration and maintenance records for the installed environmental air monitoring equipment were reviewed.

Enclosure

16 The inspectors toured the primary meteorological tower and compared local data readouts with control room data. The inspectors observed the physical condition of the tower and associated instruments and discussed equipment operability, maintenance history, and backup power supplies with responsible licensee staff. For the meteorological measurements of wind speed, wind direction, and temperature, the inspectors reviewed applicable meteorological tower instrumentation semi-annual calibration records and evaluated meteorological measurement data recovery for CYs 2009 and 2010.

The inspectors discussed previous leaks and spills, corrective actions, and reviewed monitoring results associated with the conventional waste water (WC) initial holdup pond, liquid waste recycle trench, and the reactor make-up water storage tank.

Licensee monitoring and proposed testing activities for associated buried piping for the WC holdup pond were discussed with responsible licensee representatives. Proposed changes to the licensee groundwater monitoring program based on recent investigations of groundwater intrusion into the ground water drainage A, B, and C sumps were discussed in detail. Current status and completeness of the licensees 10 CFR 50.75(g) decommissioning files were reviewed and discussed.

Procedural guidance, program implementation, quantitative analysis sensitivities, and environmental monitoring results were reviewed against 10 CFR 20; 10 CFR 50, and Appendix I; TS Sections 5.4.1 Procedures, 5.5 Programs and Manuals, and 5.6 Reporting Requirements; ODCM, Rev. 51 & 52; RG 4.15, Quality Assurance for Radiological Monitoring Programs (Normal Operation) - Effluent Streams and the Environment; and the Branch Technical Position, An Acceptable Radiological Environmental Monitoring Program - 1979.

.2 Selected Issue Follow-Up Inspection

a. Inspection Scope The inspectors selected PIP M-11-2532 associated with the failure to open the Unit 2 sight glass isolation valve during reactor coolant system draindown on March 25, 2011.

The inspectors reviewed the report to determine whether the licensee identified the full extent of the issue, performed an appropriate evaluation, and specified and prioritized appropriate corrective actions. The inspectors evaluated the licensee documents against the requirements of the licensees corrective action program and implementing procedures, and 10 CFR 50, Appendix B. Documents reviewed are listed in the Attachment.

b. Findings No findings were identified.

4OA3 Follow-up of Events and Notices of Enforcement Discretion

.1 Event Follow-Up

a. Inspection Scope The inspectors reviewed the licensees actions associated with the earthquake that occurred on August 23, 2011. The inspectors observed plant parameters for mitigating systems, evaluated performance of systems and operators, and confirmed proper classification and reporting of the event.

b. Findings No findings were identified.

.2 (Closed) Licensee Event Report (LER) 05000370/2010-002-00 and -01, Unit 2 Nuclear Service Water System A Train Past Inoperable Due to Failed Strainer Differential Pressure Instrument On September 15, 2010, the licensee identified an anomaly during the performance of a periodic high flow flush test on the A Train RN standby nuclear service water pond (SNSWP) header. While performing the test, the 2A RN strainer differential pressure (dP) instrument showed an unexpected decrease in flow as RN system flow was being increased. The licensees investigation showed that a leaking fitting on the low pressure side of the dP instrument caused differential pressure to drop below zero at high system flow. The licensee determined that the causes of the dP instrument failure were improper reassembly of an impulse line fitting during a preventative maintenance activity and an inadequate post-maintenance test. A subsequent evaluation determined that operability of the 2A RN strainer could not be assured for the period from July 24, 2010, until September 15, 2010, which exceeded TS Limiting Condition for Operation (LCO) 3.7.7 allowed outage time for a single inoperable RN train. The inspectors reviewed the Enclosure

19 LER, the licensees root cause analysis, and corrective action documents to verify accuracy of the LER and that the corrective actions were appropriate. No additional findings were identified. This LER is in the licensees corrective action program as PIP M-10-5982. The enforcement aspects of the event are discussed in Section 4OA7.

.3 (Closed) LER 05000369/2011-001-01, Shutdown of Two Units Due to Entry into LCO 3.0.3 Caused By the Inoperability of All Four Trains of the Nuclear Service Water System Due to Strainer Macro-Fouling The inspectors reviewed the subject LER revision and PIP M-11-00329 to verify the LER accuracy and appropriateness of corrective actions. The supplement to this LER provided additional details by the licensee regarding the dates of vulnerability of the RN system macro-fouling. Based on the licensees subsequent evaluation of the environmental, fish behavior patterns, and operational conditions in the area of the RN intake structure and suction strainers, the licensee believed the fish macro-fouling conditions existed no earlier than January 7, 2011, which decreased the period of vulnerability to a strainer fouling event from that which was initially believed to exist.

This information further supported the basis for the NRCs previous determination that this issue was of very low safety significance (Green) as originally documented in NRC Inspection Report 05000369, 370/2011-002 as a Non-Cited Violation (NCV) of 10 CFR 50, Appendix B, Criterion XVI, for inadequate corrective actions to prevent macro-fouling of the RN pump suction strainers. No new findings were identified. Documents reviewed are listed in the Attachment.

4OA5 Other Activities

.1 Quarterly Resident Inspector Observations of Security Personnel and Activities: 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. These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status review and inspection activities.

b. Findings

Introduction:

The NRC-identified a noncompliance of 10 CFR 50, Appendix R, Section III.G for failure to ensure that fire protection features were capable of limiting fire damage so that systems necessary to achieve and maintain cold shutdown could be repaired Enclosure

20 within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. This noncompliance was applicable to fires in fire area (FA) 14 (733 Aux Building) and FA 20 (Unit 2 Cable Room). The NRC is not taking any enforcement action for this noncompliance because it meets the criteria of the NRCs Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues.

==

Description:==

This issue was previously documented in NRC Inspection Report (IR) 05000369, 370/2000009 pending further review. As described in IR 05000369, 370/2000009, cables associated with Unit 1 Volume Control Tank (VCT) outlet valves 1NV141A and 1NV142B, and Unit 2 VCT outlet valves 2NV141A and 2NV142B, could be damaged as a result of a fire in FA 14. The power and control cables for both Unit 2 VCT outlet valves were also unprotected and could be damaged as a result of a fire in FA 20. These valves were arranged in series to ensure the VCT was isolated during a safety injection. As a result, spurious closure of a VCT outlet valve would damage the running charging pump due to loss of suction. A subsequent total loss of offsite power would result in automatic starting of the opposite train charging pump with the VCT isolated, damaging the second charging pump. During the baseline triennial fire protection inspection in 2009, the inspectors reviewed the URI, associated evaluations, and corrective actions by the licensee. As discussed in IR 05000369, 370/2009007, a charging pump was needed to achieve and maintain cold shutdown in the event of a fire in FA 14 or FA 20 because the SSF standby makeup pump does not have sufficient flow capacity to make up for the contraction of RCS coolant associated with RCS cooldown and meet the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> requirement. The licensee entered this issue into their CAP as PIPs M-00-04481 and M-09-05990, and established compensatory measures consisting of hourly fire watches in FA 14 and FA 20. The licensee plans to evaluate additional potential corrective actions and plant modifications as part of their transition to NFPA 805 in accordance with 10 CFR 50.48(c).

Analysis: The failure to ensure that fire protection features were capable of limiting fire damage so that systems necessary to achieve and maintain cold shutdown can be repaired within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, as required by 10 CFR Part 50, Appendix R, Section III.G., was a PD. The PD was more than minor because it was associated with the protection against external factors (i.e., fire) attribute and adversely affected the Mitigating Systems cornerstone objective because there would be insufficient make up capacity associated with RCS cooldown. The inspectors assessed the finding using the Fire Protection Phase 1 Worksheet contained in NRC Inspection Manual Chapter 0609, Appendix F, , and concluded that the finding was of very low safety significance (Green), because it only affected the ability to reach and maintain cold shutdown conditions. A cross-cutting aspect was not assigned because the finding did not represent current licensee performance.

Enforcement: McGuire Unit 1 Operating License Condition 2.C.(4) and Unit 2 Operating License Condition 2.C.(4) required the licensee to implement and maintain in effect all provisions of the approved Fire Protection Program as described in the Final Safety Analysis Report, as updated, for the facility and as approved in the NRC Safety Evaluation Report dated March 1978, and Supplements 2, 5, and 6 dated March 1979, April 1981, and February 1983, respectively, and the NRC Safety Evaluation Report dated May 15, 1989. The licensees approved fire protection program committed to 10 Enclosure

21 CFR 50, Appendix R,Section III.G.Section III.G specified that fire protection features shall be capable of limiting fire damage so that systems necessary to achieve and maintain cold shutdown from either the control room or emergency shutdown stations can be repaired within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Contrary to the above, since the Safety Evaluation Report issued in 1978, the licensee failed to have fire protection features capable of limiting fire damage so that systems necessary to achieve and maintain cold shutdown conditions could be repaired within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. These conditions have existed since original plant construction and were applicable to both Unit 1 and Unit 2. The NRC is exercising enforcement discretion for this nonconformance in accordance with the NRC Enforcement Policy, Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues (10 CFR 50.48), because the licensee documented their commitment to adopt NFPA 805 and change their fire protection licensing basis to comply with 10 CFR 50.48(c) prior to December 31, 2005, and it was likely this issue would have been identified and addressed during the licensees transition to NFPA 805, it was entered into the licensees corrective action program, immediate corrective action and compensatory measures were taken, it was not likely to have been previously identified by routine licensee efforts, it was not willful, and it was not associated with a finding of high safety significance (Red).

.3 (Closed) NRC Temporary Instruction (TI) 2515/179 - Verification of Licensee Responses to NRC Requirement for Inventories of Materials Tracked in the National Source Tracking System (NSTS) Pursuant to Title 10, Code of Federal Regulations, Part 20.2207 (10 CFR 20.2207)

a. Inspection Scope The inspectors reviewed the licensees source inventory records and identified a source (contained in a shielded calibration system) that met the criteria for reporting to the NSTS. The inspectors determined the presence of the source by radiation measurement using a portable radiation survey instrument. The inspectors reviewed the physical condition of the source container and discussed container locking mechanisms with the licensee. The inspectors reviewed source transaction records and information obtained from the NSTS database. Documents reviewed are listed in the Attachment.

.4 (Closed) NRC TI 2515/177, Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems (NRC Generic Letter (GL) 2008-01)

a. Inspection Scope The inspectors reviewed the implementation of the licensees actions in response to GL 2008-01, Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems. The systems reviewed included the Enclosure

22 emergency core cooling system (ECCS), decay heat removal system (ND), and containment spray system (NS). The inspectors reviewed the following:

• the licensing basis to verify that actions to address gas accumulation were consistent with the operability requirements of the subject systems

• the design of the subject systems to verify that actions taken to address gas accumulation were appropriate given the specifics of the functions, configurations, and capabilities of these systems

• the design and operation of the ND system to determine if flashing in ND suction lines would challenge system operability

• selected analyses performed by the licensee to verify that methodologies for predicting gas void accumulation, movement, and impact were appropriate

• testing implemented by the licensee to address gas accumulation in subject systems

• test procedures and completed test results to verify that test procedures were appropriate to detect gas accumulations that could challenge subject systems

• the specified testing frequencies to verify that the testing intervals had appropriately taken historical gas accumulation events as well as susceptibility to gas accumulation into account

• the test programs and processes to verify that they were sensitive to pre-cursors to gas accumulation

• corrective actions associated with gas accumulation in subject systems to verify that identified issues were being appropriately identified and corrected

• locations of selected vent valve installations to verify that the locations selected were appropriate based on piping configuration and pipe slopes The inspectors also walked down selected systems to verify that the reviews and design verifications conducted by the licensee had drawn appropriate conclusions with respect to piping configurations and pipe slope which could be result susceptible to gas accumulation. Documents reviewed are listed in the Attachment.

b. Findings

Introduction:

The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, for the failure to establish acceptance criteria to determine operability in surveillance procedures used to vent the ND system in Modes 5, 6, and No-Mode in preparation for Mode 6.

Description:

Surveillance procedures PT/1/A/4200/036, Rev 10 (Unit 1) and PT/2/A/4200/036, Rev 10 (Unit 2), Periodic Venting of ND System, were used to ensure ND system suction piping and interconnected piping was water solid by venting piping using accessible high point vents. The procedure was used in Modes 5, 6, and No-Mode in preparation for Mode 6. The ND system was required to be operable in Modes 5 and 6. Operators performed this procedure by venting accessible high points and verifying a solid water condition in the piping. If gas was detected, the procedure called for recording the gas vent time duration. The procedure was considered satisfactory as long as the as-left condition of the system was water solid. No acceptance criteria was contained in the procedure to determine if the amount of gas vented represented Enclosure

23 operability impact on the ND system and no provision was contained in the procedure to enter the corrective action program to determine if such operability impacts existed, or could reoccur following venting.

Operating experience provided by GL 2008-01 stated that surveillance requirements procedures should ensure that gas has not affected system operability and will not likely accumulate in sufficient quantity to jeopardize system operability before the next surveillance. Therefore, the inspectors determined that the licensees surveillance procedures PT/1(2)/A/4200/036 were inadequate in that they failed to establish a basis for system operability relative to gas accumulation in the ND system.

Analysis: The licensees failure to establish adequate acceptance criteria for ND venting surveillance procedures PT/1/A/4200/036 and PT/2/A/4200/036 which are used to maintain continued operability and performance capability of the system in Modes 5 and 6 was a PD. The PD was determined to be more than minor because if left uncorrected, the failure to establish acceptance criteria for surveillance tests, which established the basis for the ND system operability in modes 5 and 6, would have the potential to lead to a more significant safety concern in that conditions which impact system operability could remain undetected. In addition, the finding adversely affected the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences in that gas intrusion could result in a loss of decay heat removal capability. Using IMC 0609, Appendix G, Shutdown Operations Significance Determination Process, Attachment 1, Phase 1, the finding was determined to be of very low safety significance (Green) because a quantitative assessment was not required based on the criteria in Attachment 1. The finding had a cross-cutting aspect of implementation of operating experience in the Operating Experience component in the area of Problem Identification and Resolution because the licensee failed to implement operating experience from GL 2008-01 into station procedures P.2(b).

Enforcement: 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, required, in part, that instructions, procedures or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Contrary to the above, as of June 30, 2011, the licensee failed to include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished.

Specifically, procedures PT/1(2)/A/4200/036, Periodic Venting of ND System, provided no acceptance criteria to determine if the amount of gas vented represented operability impacts on the ND system and no provision was contained in the procedure to enter the corrective action program to determine if such operability impacts existed, or could reoccur following venting. Because this violation was determined to be of very low safety significance and has been entered into the licensees corrective action program as PIP M-11-04745, it is being treated as an NCV consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000369, 370/2011004-01, Failure to Establish Adequate ND Venting Procedures.

Enclosure

24 4OA6 Meetings, Including Exit On October 13, 2011, the resident inspectors presented the inspection results to Mr.

Regis T. Repko and other members of his staff. The inspectors confirmed that proprietary information was not provided or examined during the inspection.

4OA7 Licensee-Identified Violations The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as an NCV.

• 10 CFR 50, Appendix B, Criterion V, required, in part, that procedures for performing maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances.

This requirement included written procedures for post-maintenance testing of the RN system. Contrary to the above, written procedures for post-maintenance testing of the RN system were not appropriate to the circumstances. On July 24, 2010, following maintenance on the 2A RN strainer dP instrument loop, the licensee failed to include adequate post-maintenance instructions which would have included testing the 2A RN strainer dP instrument loop during high flow conditions experienced on the RN SNSWP supply and return header. This violation was determined not to be greater than very low safety significance (Green) because it did not represent a loss of safety function of the 2A RN train. This condition was placed in the licensees corrective action program as PIP M-10-05982.
