SUBJECT: CATAWBA NUCLEAR STATION - NRC INTEGRATED INSPECTION REPORT 05000413/2012002, 05000414/2012002 AND EXERCISE OF ENFORCEMENT DISCRECTION
Dear Mr. Morris:
On March 31, 2012, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Catawba Nuclear Station Units 1 and 2. The enclosed inspection report documents the inspection results which were discussed on April 10, 2012, 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 Commission's rules and regulations and with the conditions of your licenses. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel. This report documents one NRC-identified finding of very low safety significance (Green) which was determined to involve a violation of NRC requirements. However, because of the very low safety significance and because it was entered into your corrective action program, the NRC is treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2 of the NRC Enforcement Policy. If you contest the NCV, you should provide a written 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, 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 Catawba. In addition, if you disagree with the characterization of the 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 Catawba. The enclosed inspection report also documents one noncompliance for which the NRC is exercising enforcement discretion. The noncompliance involved the inoperability of both trains of control room area chilled water system (CRCWS) while Units 1 and 2 were operating at 100 percent RTP. The NRC is not taking enforcement action for this noncompliance because you requested, and the NRC granted, enforcement discretion for an additional 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to affect repairs to one train of CRCWS. You did return one train of CRCWS to service within the additional 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> allowed. Because your actions did not contribute to this violation, it will not be considered in the assessment process or NRC's Action Matrix.
DEC 2 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 Agencywide Documents Access and Management System (ADAMS).

SUMMARY OF FINDINGS
IR 05000413/2012-002, 05000414/2012-002; 1/1/2012 - 3/31/2012; Catawba Nuclear Station, Units 1 and 2; Flood Protection Measures
The report covered a three month period of inspection by two resident inspectors and four 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.
A NRC-identified non-cited violation (NCV) of 10 CFR Part 50, Appendix B, Criterion III, Design Control, was identified for the licensee's failure to implement the requirements of their modification program. Surface grading work for the nuclear service water (RN) piping replacement modification was not reviewed to ensure it did not impact the CMH-2 sump pump function to eliminate accumulated water. Licensee's corrective actions included unclogging the sump pump discharge outlet, replacing the sump pump, and extending the height of the discharge outlet. The performance deficiency was more than minor because it was associated with the Mitigating Systems cornerstone attribute of Protection Against External Factors - Flood Hazard and adversely affected the cornerstone objective in that the design modification activities affected the CMH-2 sump pump function to prevent water accumulation in the safety-related manhole structure. The inspectors determined that the finding was of very low safety significance because the accumulated water in CMH-2 did not result in the loss of operability or functionality of safety-related structures, systems, and components (SSCs). The finding was associated with the aspect of appropriate and timely corrective actions of the Corrective Action Program component in the Problem Identification and Resolution cross-cutting area in that the licensee identified in August 2011 (PIP C-11-6342) that the sump pump discharge outlet needed to be raised; however, corrective actions were not implemented that would have prevented the blockage during the grading activities. P.1(d) (Section 1R06)
REPORT DETAILS
Summary of Plant Status Unit 1 operated at or near 100 percent Rated Thermal Power (RTP) for the entire inspection period. Unit 2 operated at or near 100 percent RTP until March 10, 2012, when the unit was shut down for a refueling outage.
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity 1R01 Adverse Weather Protection
a. Inspection Scope
Adverse Weather Conditions: The inspectors reviewed the licensee's severe weather actions following a tornado watch issued on February 24, 2012. This included a review of actions required by RP/0/A/5000/007, Natural Disaster and Earthquake, Enclosure 4.1, to verify that the design features and implementation of the licensee's procedures protected mitigating systems from adverse weather effects. Documents reviewed are listed in the Attachment. Flood Protection Measures - External: The inspectors reviewed the licensee's external flood protection features. The inspectors performed a walkdown of external site areas including designated Type I inlet catch basins on-site, cooling tower yard berms, and diesel generator room access curbs and seals which are designed to protect safety-related facilities from flooding during a local probable maximum precipitation event. The walkdown included observing that the steel gratings on four sides and top of the basins were intact. To the extent possible, the inspectors visually observed the basins and pipe cavities to determine that the areas were free of debris accumulation and that no significant blockage of the drains was apparent. The inspectors also observed the condition of berms and seals to verify that their physical condition had not degraded and that they were able to fulfill their designed functions. The inspectors reviewed the corrective action program documents to ascertain that the licensee was identifying issues and resolving them. Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
1R04 Equipment Alignment
a. Inspection Scope
Partial Walkdowns: The inspectors performed three partial system walkdowns during the activities listed below to assess the operability of redundant or diverse trains and components when safety-related equipment was inoperable. The inspectors performed walkdowns to identify any discrepancies that could impact the function of the system and, therefore, potentially increased risk. The inspectors reviewed applicable operating procedures and walked down system components, selected breakers, valves, and support equipment to determine if they were in the correct position to support system operation. The inspectors reviewed protected equipment sheets, maintenance plans, and system drawings to determine if the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the corrective action program. Documents reviewed are listed in the Attachment.
- Unit 2 turbine driven auxiliary feed water pump and 'B' train motor driven auxiliary feed water pump (MDCAP) while the 'A' train MDCAP was out of service
b. Findings

1R06 Flood Protection Measures
a. Inspection Scope
The inspectors entered conduit manhole (RN conduit) CMH-2 to verify that the cables were not submerged, that the cables were not damaged or degraded, and that the sump pumps were functioning properly.
b. Findings
Introduction:
A Green NRC-identified NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, was identified for the licensee's failure to implement the requirements of their modification program. Surface grading work for the RN piping replacement modification was not reviewed to ensure it did not adversely impact the CMH-2 sump pump function to eliminate accumulated water.
Description:
During a walkdown of CMH-2, the inspectors noted that the sump pump discharge pipe appeared to be buried as a result of grading work in the area following an RN piping replacement modification. The licensee removed dirt and gravel from the area where the sump pump discharge pipe exited from the manhole structure and found the discharge outlet was blocked. Further investigation revealed that the sump pump had failed due to the blocked discharge outlet and approximately three feet of water had accumulated in the bottom of the manhole up to the lowest cable penetrations and partially submerged one of the safety-related RN cables. Procedure EDM 601, Engineering Change Manual, Appendix K, Engineering Review Screen for Design Changes, required a review to determine if the modification had the potential to impact previously installed features that mitigate the effects of external flooding. The licensee recognized that grading elevations would be changed by the RN piping replacement modification, but did not identify the potential impact on the CMH-2 sump pump discharge outlet. As a result, the discharge outlet was blocked during RN pipe replacement backfill and grading activities causing failure of the sump pump which allowed water to accumulate in the manhole. Corrective actions included unclogging the sump pump discharge outlet, replacing the sump pump, and extending the height of the discharge outlet.
Analysis:
The failure to implement the requirements of the modification program to verify that the RN piping replacement activities did not affect external flood mitigation features was a PD. The PD was more than minor because it was associated with the Mitigating Systems cornerstone attribute of Protection Against External Factors - Flood Hazard and adversely affected the cornerstone objective in that the design modification activities affected the CMH-2 sump pump function to prevent water accumulation in the safety-related manhole structure. The inspectors used IMC 0609, Attachment 4, and determined that the finding was of very low safety significance because the accumulated water in CMH-2 did not result in the loss of operability or functionality of safety-related SSCs. The finding was associated with the aspect of appropriate and timely corrective actions of the Corrective Action Program component in the Problem Identification and Resolution cross-cutting area in that the licensee identified in August 2011 (PIP C-11-6342) that the sump pump discharge outlet needed to be raised; however, corrective actions were not implemented. P.1(d)
Enforcement:
10 CFR Part 50, Appendix B, Criterion III, Design Control, required, in part, that design control measures shall provide for verifying the adequacy of design such as design reviews. Procedure EDM 601 required a design review to determine if the modification had the potential to impact previously installed features that mitigate the effects of external flooding. Contrary to the above, from late 2011 to March 2012 design control measures for verifying the adequacy of design were not implemented. The licensee's design review failed to verify that the safety-related cable manhole CMH-2 sump pump water removal function would not be impacted by RN piping replacement grading activities. Because this violation was of very low safety significance and has been entered into the licensee's corrective action program as PIP C-12-1838, it is being treated as a non-cited violation consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000413/2012002-01, Safety-Related Manhole Sump Pump Discharge Outlet Blockage.
1R07 Heat Sink Performance
a. Inspection Scope

The inspectors reviewed the system configuration associated with the test, heat load requirements, the methodology used in calculating heat exchanger performance, and the method for tracking the status of tube plugging activities via the data logger and computer processing equipment. Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
1R08 Inservice Inspection Activities
a. Inspection Scope
Non-Destructive Examination Activities and Welding Activities: The inspectors reviewed the implementation of the licensee's Inservice Inspection (ISI) Program for monitoring degradation of the reactor coolant system, steam generator tubes, risk-significant piping and components and containment systems. The inspectors reviewed non-destructive examinations (NDEs) to evaluate compliance with the applicable edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC),
Section XI (Code of record: 1998 Edition through 2000 Addenda), and to verify that indications and defects (if present) were appropriately evaluated and dispositioned in accordance with the requirements of the ASME Code, Section XI, acceptance standards.
The inspectors observed the following non-destructive examinations to evaluate compliance with the ASME Code Section XI and Section V requirements and to evaluate if any indications or defects were dispositioned in accordance with the ASME Code or an NRC-approved alternative requirement.

The inspectors reviewed records of the BMV examination to evaluate if the activities were conducted in accordance with the requirements of ASME Code Case N-729-1 and 10 CFR 50.55a(g)(6)(ii)(D). The inspectors evaluated if the required visual examination scope/coverage was achieved and any limitations were recorded in accordance with the licensee procedures. Additionally, the inspectors evaluated if the licensee's criteria for visual examination quality and instructions for resolving interference and masking issues were consistent with 10 CFR 50.55a. The licensee did not identify any relevant indications that were accepted for continued service during the bare metal visual exam. The licensee did not perform any welded repairs to vessel head penetrations since the beginning of the preceding Unit 2 refueling outage.
Boric Acid Corrosion Control (BACC) Inspection Activities: The inspectors reviewed the licensee's BACC program activities to ensure implementation with commitments made in response to NRC Generic Letter 88-05, "Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary," and applicable industry guidance documents. Specifically, the inspectors performed an on-site record review of procedures and the results of the licensee's containment walk-down inspections performed during the current spring refueling outage. The inspectors also interviewed the BACC program owner, conducted an independent walk-down of containment to evaluate compliance with licensee's BACC program requirements, and verified that degraded or non-conforming conditions, such as boric acid leaks, were properly identified and corrected in accordance with the licensee's BACC and corrective action programs. The inspectors reviewed the following condition reports and associated corrective actions related to evidence of boric acid leakage to evaluate if the corrective actions completed were consistent with the requirements of the ASME Code Section XI and 10 CFR 50, Appendix B, Criterion XVI.
- C-11-03283, Active boron leakage
- C-11-08112, 2NV205 leaking from plug on body of valve
- C-11-08940, Active boron leak, excessive boron buildup The inspectors reviewed the following licensee evaluations of reactor coolant system components with boric acid deposits to evaluate if degraded components were documented in the corrective action program. The inspectors also evaluated the corrective actions for any degraded reactor coolant system components against the component ASME Code Section XI and other licensee committed documents:

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: During facility tours, the inspectors observed labeled radioactive material, postings for radiation areas and high radiation areas (HRAs), in the radiologically controlled area (RCA), radioactive materials control tent, Independent Spent Fuel Storage Installation, Unit 2 Containment, and other storage locations. Inspectors also observed and evaluated labels on selected containers in those selected locations. The inspectors reviewed survey records for several plant areas including surveys for alpha emitters, hot particles, airborne radioactivity, gamma surveys within areas of high dose rate gradients, and pre-job surveys for upcoming tasks. Inspectors independently surveyed areas in the plant and compared results to radiological conditions and postings in the plant. Inspectors also reviewed air sample records and observed work in potential airborne areas to assess the location of air monitors. This included the activities associated with Unit 2 'D' nuclear coolant pump (NCP) Seal Work, bullet nose repair, and SG work platforms. The inspectors discussed changes to plant operations that could contribute to changing radiological conditions since the last inspection. Inspectors attended pre-job briefings for selected outage tasks and reviewed radiation work permits (RWP) details to assess communication of radiological control requirements and current radiological conditions to workers to include radiography, steam generator eddy current testing, 2D NCP Seal Work, and bullet nose repair activities. RWPs for work in airborne areas were also reviewed to assess airborne radioactive controls and monitoring to include 2D NCP Seal Work, Conoseal Assembly and Removal, bullet nose repair, and S/G work platforms. Hazard Control and Work Practices: The inspectors evaluated access barrier effectiveness including key control for selected Unit 1 and Unit 2 locked HRA (LHRA), and very HRA (VHRA) locations. Changes to procedural guidance for LHRA and VHRA controls were discussed with Radiation Protection (RP) supervisors and Control Room Operators. Controls and their implementation for storage of irradiated material within the spent fuel pool (SFP) were reviewed and discussed the SFP Reactor Engineer. Areas where dose rates could change significantly as a result of plant shutdown and refueling operations were also discussed.
Occupational workers' adherence to selected RWPs and RP technician (RPT) proficiency in providing job coverage were evaluated through direct observations and interviews with licensee staff of selected activities. Electronic dosimeter (ED) alarm set points and worker stay times were evaluated against area radiation survey results for jobs in upper and lower containment, lower annulus, and the Auxiliary Building. ED alarm logs were reviewed and worker response to dose and dose rate alarms for selected work activities was evaluated. RPT coverage and actions at the Unit 2 lower and upper containment single point of accesses (SPAs) were reviewed and discussed in detail.
Control of Radioactive Material: The inspectors observed the release of potentially contaminated materials and personnel from the RCA and SPAs with the use of small article monitors, personnel contamination monitors, and portal monitor instruments. The inspectors discussed equipment sensitivity, alarm setpoints, and release program guidance with licensee staff. In addition, the inspectors reviewed controls for hand surveying large tools and equipment for release from the RCA and SPAs. The inspectors compared recent 10 CFR Part 61 results for the Dry Active Waste radwaste stream with radionuclides used in calibration sources to evaluate the appropriateness and accuracy of release survey instrumentation. The inspectors also reviewed source inventory and discussed leak tests for selected sealed sources and discussed nationally tracked source transactions with RP staff. Problem Identification and Resolution: The inspectors reviewed selected PIPs associated with radiological hazard assessment and control. The reviewed items included selected PIPs, self-assessments, and quality assurance audit documents. The inspectors evaluated the licensee's ability to identify and resolve the issues in accordance with procedure NSD 208, Problem Investigation Program, Revision (Rev.) 33.
RP activities were evaluated against the requirements of UFSAR Chapter 12; TS Section 5.7; 10 CFR Parts 19 and 20; and approved licensee procedures. Licensee programs for monitoring materials and personnel released from the RCA and SPA were evaluated against 10 CFR Part 20, and IE Circular 81-07, Control of Radioactively Contaminated Material. Documents reviewed are listed in the Attachment. The inspectors completed all specified line-items detailed in Inspection Procedure (IP) 71124.01 (sample size of 1).
b. Findings
No findings were identified.
2RS2 Occupational ALARA (As Low As Reasonably Achievable) Planning and Controls
a. Inspection Scope
Work Planning and Exposure Tracking: The inspectors reviewed exposure estimate planning for selected work activities. ALARA planning packages were reviewed for the following high collective exposure tasks: SG primary side work; reactor head disassembly and re-assembly; and shielding installation and removal. For the selected tasks, the inspectors reviewed established dose goals and discussed assumptions regarding the bases for the current estimates with responsible ALARA planners. The inspectors evaluated the incorporation of exposure reduction initiatives and operating experience, including historical post-job reviews, into RWP requirements. Day-to-day collective dose data for the selected tasks were compared with established dose estimates and evaluated against procedural criteria (trigger points) for additional ALARA review. Where applicable, changes to established estimates were discussed with ALARA planners and evaluated against work scope changes or unanticipated elevated dose rates. The inspectors also reviewed and discussed the minutes from ALARA Committee meetings held in 2011. Source Term Reduction and Control: The inspectors reviewed the collective exposure three-year rolling average from 2008 - 2010. The inspectors reviewed historical dose rate trends for reactor coolant system piping and compared them to current outage data. Source term reduction initiatives such as crudburst/cleanup, zinc injection, fuel cleaning, and the use of temporary shielding were reviewed and discussed with Chemistry and RP staff. Radiation Worker Performance: The inspectors observed radiation worker performance via remote monitoring during primary side SG activities including manway removal and nozzle dam installation. Radiation worker and RPT performance was also observed and evaluated in Section 2RS1. Problem Identification and Resolution: The inspectors reviewed and discussed selected Corrective Action Program documents associated with ALARA program implementation. The inspectors evaluated the licensee's ability to identify and resolve the issues in accordance with NSD 208, Problem Investigation Program, Rev. 33. The inspectors also evaluated the scope and frequency of the licensee's self-assessment program and reviewed recent assessment results. ALARA program activities were evaluated against the requirements of UFSAR Section 12, TS Section 5.4, 10 CFR Parts 19 and 20, and approved licensee procedures. Documents reviewed are listed in the Attachment. The inspectors completed all specified line-items in IP 71124.02 (sample size of 1).
b. Findings
No findings were identified.
OTHER ACTIVITIES
4OA1 Performance Indicator Verification
a. Inspection Scope
The inspectors sampled licensee data to confirm the accuracy of reported performance indicator (PI) data for the eight indicators during periods listed below.

(Closed) Licensee Event Report (LER) 05000413/2011-003-00, Technical Specification Required Shutdown of Unit 1 and 2 and Associated Technical Specification Violation Involving Notice of Enforcement Discretion Due to Two Inoperable Trains of the Control Room Area Chilled Water System (CRACWS) (NOED 11-2-004)
a. Inspection Scope
In NRC Integrated Inspection Report 05000413, 414/2011005, a URI was opened for the issuance of NOED 11-2-004. The inspectors reviewed the associated LER, root cause evaluation, and corrective actions to determine if any performance deficiencies contributed to the need for the NOED. Documents reviewed are listed in the
.
b. Findings
Description:
On December 15, 2011, CRACWS train B unexpectedly tripped while CRACWS train A was out of service for scheduled maintenance. TS LCO 3.7.11, Condition "E" required immediate entry into TS LCO 3.0.3. The licensee was granted a NOED from compliance with TS LCO 3.0.3 to allow the units to remain in MODE 3 for an additional 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to return the train A of CRACWS to service. The inspectors concluded that the loss of CRACWS train B was due to a random shutdown of a digital controller which was not a result of licensee performance. This condition was determined to be of very low safety significance because the licensee had alternate means of providing cooling to maintain control room habitability during the NOED period.
Enforcement:
TS 3.0.3 required in part that the units be placed in Mode 3 within 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />, Mode 4 within 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />, and Mode 5 within 37 hours4.282407e-4 days <br />0.0103 hours <br />6.117725e-5 weeks <br />1.40785e-5 months <br />. Contrary to the above, the times specified by TS 3.0.3 were not met. However, because no performance deficiency was identified, no enforcement action is warranted for this violation of NRC requirements in accordance with the NRC's Enforcement Policy. Further, because licensee actions did not contribute to this violation, it will not be considered in the assessment process or the NRC's Action Matrix.
4OA5 Other Activities
.1 Quarterly Resident Inspector Observations of Security Personnel and Activities
