SUBJECT:
ST. LUCIE PLANT - NRC INTEGRATED INSPECTION REPORT 05000335/2013005, 05000389/2013005, 05000335/2013502 AND 05000389/2013502
Dear Mr. Nazar:
On December 31, 2013, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your St. Lucie Plant Units 1 and 2. The enclosed integrated inspection report documents the inspection results, which were discussed on January 9, 2014, with Mr. Coffey and other members of your staff.
One self-revealing finding and one NRC-identified finding of very low safety significance (Green)
were identified during this inspection. Both of these findings involved violations of NRC requirements. The NRC is treating these violations as non-cited violations (NCVs) consistent with Section 2.3.2.a of the Enforcement Policy.
If you contest these violations or significance of these NCVs, you should provide a 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 DC 20555-0001; with copies to the Regional Administrator Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the St. Lucie Plant.
If you disagree with a cross-cutting aspect assignment 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 the St. Lucie Plant.
As a result of the Safety Culture Common Language Initiative, the terminology and coding of cross-cutting aspects were revised beginning in calendar year (CY) 2014. New cross-cutting aspects identified in CY 2014 will be coded under the latest revision to Inspection Manual Chapter (IMC) 0310. Cross-cutting aspects identified in the last six months of 2013 using the previous terminology will be converted to the latest revision in accordance with the cross-reference in IMC 0310. The revised cross-cutting aspects will be evaluated for cross-cutting themes and potential substantive cross-cutting issues in accordance with IMC 0305 starting with the CY 2014 mid-cycle assessment review. In accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding, 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 the NRCs document system (ADAMS).

SUMMARY OF FINDINGS
IR 05000335/2013005, 05000389/2013005; 10/01/2013 - 12/31/2013; St. Lucie Nuclear Plant,
Units 1 & 2; Identification and Resolution of Problems, In-Plant Airborne Radioactivity Control and Mitigation The report covered a three month period of inspection by the resident inspectors, regional specialist inspectors, and a headquarters specialist inspector. The significance of inspection findings are indicated by their color (i.e., greater than Green, or Green, White, Yellow, or Red)and determined using Inspection Manual Chapter (IMC) 0609, Significance Determination Process, (SDP) dated June 2, 2011. The cross-cutting aspect was determined using IMC 0310, Components Within the Cross-Cutting Areas, dated October 28, 2011. All violations of NRC requirements were dispositioned in accordance with the NRCs Enforcement Policy dated July 9, 2013. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision
NRC-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
The inspectors identified a non-cited violation (NCV) of 10 CFR Part 50, Appendix B,
Criterion XVI, Corrective Action. Specifically, the licensee failed to identify localized corrosion on the discharge piping for the 1C auxiliary feedwater pump that exceeded the licensees acceptance criteria for minimum pipe wall thickness. The licensee entered the issue into the corrective action program (CAP) as action request (AR) 1913575. Corrective actions included replacing the degraded sections of pipe and conducting analyses to verify past operability of the degraded piping.
The performance deficiency was more than minor because if left uncorrected, it had the potential to lead to a more significant safety concern. Specifically, unmitigated corrosion of the AFW piping could result in through-wall leaks, affect structural integrity of the piping, and ultimately result in inoperability of the system. Using Table 2 of Manual Chapter 0609.04,
Significance Determination Process (SDP) Initial Characterization of Findings dated June 19, 2012; the inspectors concluded the finding affected the mitigating systems cornerstone. The inspectors evaluated the finding using IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, dated June 19, 2012. The finding was determined to be of very low safety significance (Green) since the AFW system remained operable and was able to perform its function. The inspectors determined the cause of this finding was associated with a cross cutting aspect of minimizing longstanding equipment issues in the resources component of the human performance area. Specifically, the licensee had not provided adequate resources to address longstanding Unit 1 AFW system corrosion issues H.2(a).
(Section 4OA2.4)
Cornerstone: Occupational Radiation Safety
- Green.
A self-revealing non-cited violation (NCV) of 10 CFR Part 20.1703(a) was identified for the use of respiratory protection equipment that had not been certified as safe by the National Institute for Occupational Safety and Health (NIOSH). The licensees use of respiratory protection equipment in a radiologically controlled area that had not been tested and certified by NIOSH or that had not obtained prior authorization from the NRC to use respiratory equipment not certified by NIOSH was a performance deficiency. The licensee discontinued use of the respiratory protection equipment and the issue was entered into the licensees corrective action program under action request (AR) 1719479.
The finding was more than minor because it was associated with the Occupational Radiation Safety cornerstone attribute of Equipment and Instrumentation and adversely affected the cornerstone objective of protecting worker health and safety from exposure to radiation. When using non-NIOSH approved respirators in a radiologically controlled area, the potential existed to put workers in a situation that may be more hazardous than the radiological dangers that the respirator is meant to protect against (e.g. loss of air flow). The finding was determined to be of very low safety significance (Green) because it was not related to As Low As Reasonably Achievable (ALARA) planning, there was no overexposure nor potential for overexposure, and the licensees ability to assess dose was not compromised. A cross cutting aspect was not assigned because the performance characteristic was corrected and eliminated before the inspectors identified the issue and is therefore not reflective of present licensee performance.
(Section 2RS3)
Licensee Identified Violations
None
REPORT DETAILS
Summary of Plant Status
Unit 1 began the inspection period in a shutdown condition for a planned refueling outage (RFO). At the completion of the RFO, the reactor was restarted on November 7. On November 10, power was rapidly reduced from approximately 49 percent to 12 percent rated thermal power (RTP) due to a main generator digital electrohydraulic (DEH) control oil system leak. On November 12, the unit was manually tripped from approximately 90 percent RTP when another leak developed in the DEH system. The unit was restarted on November 13 and reached 100 percent RTP on November 15. On December 11, the unit was shutdown to support a planned replacement of a degrading 1A2 reactor coolant pump (RCP) seal. On December 18, the unit was restarted and reached 100 percent power on December 19. The unit was at 100 percent power for the remainder of the inspection period.
Unit 2 began the inspection period at 100 percent RTP. On November 14, the unit was manually tripped when the operators noticed lowering B steam generator water level due to an unplanned closure of a feedwater valve. The unit was restarted on November 16 and reached 100 percent RTP on November 17. On December 4, the 2B heater drain pump tripped which resulted in a downpower to 94 percent RTP. Reactor power was restored to 100 percent RTP on December 6, where it remained through the end of the inspection period.

==1R01 Adverse Weather Protection Seasonal Winter Weather Conditions
a. Inspection Scope
==
The inspectors reviewed implementation of cold weather preparations as described in procedure 0-NOP-99.06, Cold Weather Preparations. The inspectors verified conditions were met for entering the subject procedure and that equipment status was verified as directed by the procedure. The inspectors performed a walk down of the following safety-related equipment on both units that are exposed to the outside weather conditions to identify any potential adverse conditions. Action requests (ARs) were checked to ensure that the licensee was identifying and resolving weather related issues and that corrective actions from the previous cold weather season had been satisfactorily resolved.
- Unit 1 and Unit 2 emergency diesel generator (EDG) rooms
- Unit 1 and Unit 2 refueling water tank areas
- Unit 1 and Unit 2 main feed isolation valve areas
- Unit 1 and Unit 2 auxiliary feed water (AFW) pump areas

The inspectors reviewed results of the eddy current examination activities performed in the Unit 1 steam generators during refueling outage SL1-25 to verify compliance with the licensees Technical Specifications, ASME Section XI, and Nuclear Energy Institute (NEI) 97-06, Steam Generator Program Guidelines. The inspectors reviewed documentation associated with the steam generator inspections and integrity assessments as described below.
The inspectors reviewed the scope of the eddy current examinations to verify that known and potential areas of tube degradation were inspected. The inspectors also verified that inspection scope expansion criteria were implemented based on inspection results as directed by the Electric Power Research Institute (EPRI) Pressurized Water Reactor Steam Generator Examination Guidelines, Revision 7.
The inspectors compared the recent eddy current examination results with the last Condition Monitoring and Operational Assessment report to assess the licensees prediction capability for maximum tube degradation and number of tubes with indications. The inspectors verified that the licensees evaluation was conservative and that current examination results were bound by the Operational Assessment projections.
The inspectors reviewed the previous Operational Assessment to verify the licensee met the inspection frequency established in the plant Technical Specifications and had evaluated the acceptability of these steam generators to meet the tube integrity performance criteria until the next scheduled inspection.
The inspectors also compared past examination results discussed in the latest Degradation Assessment with the recent eddy current examination results to verify that any new degradation mechanisms were identified and evaluated before plant startup.
The review of eddy current examination results included the disposition of potential loose part indications on the steam generator secondary side to verify that corrective actions for evaluating and retrieving loose parts were consistent with the EPRI Guidelines. The inspectors also reviewed a sample of primary-to-secondary leakage data for the last Unit 1 operating cycle to obtain reasonable assurance that operational leakage in all steam generators remained below the detection or action level thresholds during the previous operating cycle.
In addition, the inspectors reviewed a sample of site-specific Examination Technique Specification Sheets (ETSSs) to ensure that their qualification and site-specific implementation were consistent with Appendix H or I of the Electric Power Research Institute Pressurized Water Reactor Steam Generator Examination Guidelines, Revision 7. The reviewed ETSSs were selected based on plant-specific degradation mechanisms of interest to the inspectors and industry operating experience. The inspectors selected bobbin probe ETSSs qualified for detection and sizing of loose part wear in tube freespan locations, thinning in tube support plates and top-of-tubesheet, and wear at tube support plates and anti-vibration bars. The inspectors also selected rotating and array probe ETSSs for detection of circumferential and axial stress corrosion cracking on the internal and external surfaces of the tubes at the expansion transition area.
Based on the review of eddy current examination results for steam, the inspectors confirmed that no new degradation mechanisms were identified, none of the SG tubes examined met the criteria for in-situ pressure testing, and none of the indications left in service required repair.

2RS2 As Low As Reasonably Achievable (ALARA)
a. Inspection Scope
ALARA Program Status: The inspectors reviewed and discussed plant exposure history and current trends including the sites three-year rolling average (TYRA) collective exposure history for calendar year (CY) 2010 through CY 2012. Current and proposed activities to manage site collective exposure and trends regarding collective exposure were evaluated through review of previous TYRA collective exposure data and review of the licensees 5-year ALARA program implementing plan. Current ALARA program guidance and recent changes, as applicable, regarding estimating and tracking exposure were discussed and evaluated.
Radiological Work Planning: The inspectors reviewed planned work activities and their collective exposure estimates for SL1-25 and the stations applications of lessons learned from work performed during SL1-24. Work activities, exposure estimates and mitigation activities were reviewed for the following high collective exposure tasks:
reactor head work, pressurizer (PZR) heater work, reactor coolant pump (RCP) motor replacement work and balance of plant scaffold management.
For the selected tasks, the inspectors reviewed dose mitigation actions and established dose goals. During the inspection, use of remote technologies including teledosimetry and remote visual monitoring were verified as specified in RWP or procedural guidance.
Current collective dose data for selected tasks were compared with established estimates and, where applicable, changes to established estimates were discussed with responsible licensee ALARA planning representatives. The inspectors reviewed previous post-job reviews conducted for the SL1-24 and verified that the items were entered into the licensees corrective action program for evaluation.
Verification of Dose Estimates and Exposure Tracking Systems: The inspectors reviewed select ALARA work packages and discussed assumptions with responsible planning personal regarding the bases for the current estimates. The licensees on-line RWP cumulative dose data bases used to track and trend current personal and cumulative exposure data and/or to trigger additional ALARA planning activities in accordance with current procedures were reviewed and discussed. Selected work-in-progress reviews for work exceeding the dose budget for SL1-24 including modification work for the extended power uprate and adjustments to cumulative exposure estimate data were evaluated against work scope changes or unanticipated elevated dose rates.
Source Term Reduction and Control: The inspectors reviewed historical dose rate trends for shutdown chemistry, cleanup, and resultant chemistry and radiation protection trend-point data against the current SL1-25 data as well as licensees implementation and evaluation of the results of implementation of zinc injection. Licensee programs implementing noble gas and iodine mitigation strategies to minimize exposures resulting from fuel leaks were discussed with plant staff.

2RS3 In-Plant Airborne Radioactivity Control and Mitigation
a. Inspection Scope
Plant Airborne Radioactivity Controls and Mitigation: The inspectors reviewed the plants UFSAR and current SL1-25 tasks to identify potential airborne radiation areas, and associated ventilation systems and monitoring instrumentation. Selected licensee documents including TS, UFSAR, design basis documents, and procedures associated with plant airborne radioactivity controls and monitoring, and with respiratory protection program implementation were reviewed and discussed with cognizant licensee representatives.
Engineering Controls: Licensee engineering controls to control and mitigate airborne radioactivity were reviewed and discussed. The inspectors evaluated engineering controls use for radiation protection purposes, including operation of the SL1&2 Reactor Containment Building (RCB) purge and installation of temporary HEPA systems used at the Steam Generator Blowdown Treatment Facility and selected SL1-25 work activities.
The evaluation included procedural guidance, operability testing, and established configurations. In addition, plant guidance and its implementation for monitoring beta-gamma and alpha-emitting radionuclides for airborne conditions were reviewed and discussed with licensee representatives.
Use of Respiratory Protection Devices: Program guidance for issuance and use of respiratory protection devices were reviewed and discussed with responsible licensee representatives. The inspectors reviewed Total Effective Dose Equivalent (TEDE)-
ALARA evaluations for selected SL1-25 outage activities. Selected whole-body count (WBC) routine and investigative analysis results for occupational workers were reviewed and discussed. Use of respiratory protective equipment was evaluated for the workers involved in the SL1 V-4111 work activities and SL1 reactor cavity surveys. The inspectors toured selected onsite compressors available to supply breathing air for current outage activities and verified Grade D air certification for all staged compressors.
Training, fit testing, and medical qualifications for selected HP staff, licensed operators, carpenters, and emergency duty staff involved in respiratory protection activities to include SL1-25 work associated with SL1 V-4111 and SL1 reactor cavity surveys were reviewed and verified.
Self-Contained Breathing Apparatus (SCBA) for Emergency Use: The inspectors verified current status, operability and availability of select SCBA equipment maintained within the firehouse, operations support center, Unit 1 and 2 control rooms, and reactor auxiliary building (RAB). Maintenance activities for selected respiratory protective equipment, e.g., compressed gas cylinders, regulators, valves, and hose couplings, by certified vendor technicians was verified for selected SCBA units. Training, fit testing, and medical qualifications for selected HP, maintenance, I&C, and Ops staff assigned Emergency Response Organization (ERO) duties were reviewed and verified. For selected SL1 and SL2 control room operators, the inspectors discussed and verified annual hands-on SCBA training activities including donning, doffing and functionally checking SCBA equipment and availability of corrective lens.
Problem Identification and Resolution: The inspectors reviewed selected CAP documents within the areas of radiological airborne controls and respiratory protection activities. The inspectors evaluated the licensees ability to identify and resolve the issues in accordance with PI-AA-204, Condition Identification and Screening Process, and PI-AA-205, Condition Evaluation and Corrective Action. The inspectors also evaluated the scope of the licensees internal audit program and reviewed recent assessment results. Licensee CAP documents reviewed are listed in the Attachment.

Documents reviewed are listed in the
.
b. Findings
Introduction:
A self-revealing Green NCV of 10 CFR Part 20.1703(a) was identified related to the licensees use of respiratory protection equipment. Specifically, the licensee failed to use respiratory protection equipment that had been tested and certified by NIOSH to limit the intake of radioactive material as required by 10 CFR 20.1703(a).
Description:
On December 27, 2011, the licensee received a shipment of powered air-purifying respirator (PAPR) hoods with a serial number different from those in inventory.
The licensee questioned the vendor on the change in serial number and was informed that the new shipment of PAPR hoods were NIOSH-certified. At this point, the licensee recognized the PAPR hoods used previously had not been NIOSH-certified. For a period of approximately one year before December 27, 2011, licensee workers used non-NIOSH certified PAPR hoods in a radiologically controlled area (RCA) for activities associated with insulation removal and installation, reactor head support services, and decontamination. The hoods were used by the licensee to relieve heat stress in the RCA. The inspectors noted that the PAPR hoods had not undergone a NIOSH certified testing program to ensure their intrinsic safety. PAPR hoods can fail and potentially inhibit breathing with no powered air flow. Inhalation/exhalation issues, along with other potential safety hazards such as hearing damage from the fan motor and flammability of the device, would be evaluated as part of the NIOSH certification process. The inspectors noted that no injuries occurred as a direct result of the use of these respirators by licensee workers.
Analysis:
The licensees failure to use respiratory protection equipment that had been tested and certified by NIOSH to limit the intake of radioactive material as required by 10 CFR 20.1703(a) was a performance deficiency. The finding is more than minor because it is associated with the Occupational Radiation Safety cornerstone attribute of Equipment and Instrumentation and adversely affected the cornerstone objective of protecting worker health and safety from exposure to radiation. Specifically, the use of uncertified respirators in an RCA creates the potential to put workers at an occupational health and safety risk greater (e.g. loss of air flow) than the radiological dangers that the respirator is meant to protect against. The finding was assessed using Appendix C, Occupational Radiation Safety Significance Determination Process (dated August 19, 2008) of IMC-0609, Significance Determination Process. The finding was determined to be of very low safety significance (Green) because it was not an ALARA planning issue, there was no overexposure or potential for overexposure, and the licensees ability to assess dose was not compromised. A cross cutting aspect was not assigned because the performance characteristic was corrected and eliminated before the inspectors identified the issue and is therefore not reflective of present licensee performance.
Enforcement:
10 CFR Part 20.1703 states that, If the licensee assigns or permits the use of respiratory protection equipment to limit the intake of radioactive material;
- (a) The licensee shall use only respiratory protection equipment that is tested and certified by the National Institute for Occupational Safety and Health (NIOSH) except as otherwise noted in this part, or
- (b) If the licensee wishes to use equipment that has not been tested or certified by NIOSH, or for which there is no schedule for testing or certification, the licensee shall submit an application to the NRC for authorized use of this equipment except as provided in this part. The application must include evidence that the material and performance characteristics of the equipment are capable of providing the proposed degree of protection under anticipated conditions of use. This must be demonstrated either by licensee testing or on the basis of reliable test information. Contrary to the above, for approximately a year before December 27, 2011, the licensee used respiratory protection equipment that had neither been tested and certified by NIOSH nor received authorization from the NRC to do so. Specifically, the PAPR hoods were used in a radiologically controlled area. The licensee discontinued use of the non-NIOSH certified respiratory protection equipment as part of their immediate corrective actions and the issue was entered into the licensees corrective action program under AR 1719479. Because the failure to comply with 10 CFR Part 20.1703 was of very low safety significance and has been entered into the licensees corrective action program, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 050000335, 389/2013005-01: Failure to Use Only NIOSH Certified Respiratory Protection Equipment.
2RS4 Occupational Dose Assessment
a. Inspection Scope
The inspectors evaluated current RP program activities and results associated with internal and external radiation exposure monitoring of occupational workers. The review included program guidance, equipment and changes, as applicable; quality assurance activities, results, and responses to identified issues; and individual dose results for occupational workers.
External Dosimetry: The inspectors reviewed and discussed RP program guidance for monitoring external and internal radiation exposures of occupational workers. The inspectors verified National Voluntary Laboratory Accreditation Program (NVLAP)certification data and discussed program guidance for storage, processing and results for active and passive personnel dosimeters currently in use. Comparisons between direct reading dosimeter (DRD) and thermoluminescent dosimeter (TLD) data were reviewed and discussed.
Internal Dosimetry: Program guidance, instrument detection capabilities, and select results for the internally deposited radionuclides were reviewed in detail. The inspectors reviewed routine termination and follow-up in vivo (WBC). In addition, guidance for collection and conduct of special bioassay sampling were discussed to include an event associated with individual who fell into the SL2 SFP cask pit area.
Special Dosimetric Situations: The inspectors reviewed monitoring conducted and results for special dosimetric situations. The methodology and results of monitoring occupational workers within non-uniform external dose fields were evaluated. In addition, the adequacy of dosimetry program guidance and its implementation were reviewed for shallow dose assessments and calculations for discrete radioactive particle skin contamination events. Neutron monitoring conducted in support of ISFSI loading and transport operations during 2012 and 2013 was reviewed and discussed. There have been no declarations of pregnancy by workers during the last 3 years. However, inspectors reviewed licensee procedures for monitoring declared pregnant workers. In addition, proficiency of RP staff involved in conducting skin dose assessments, neutron monitoring, and WBC equipment operations were evaluated through direct interviews, onsite observations, and review and discussions of completed records and supporting data.
Problem Identification and Resolution: The inspectors reviewed and discussed selected CAP documents associated with occupational dose assessment. The reviewed items included ARs, self-assessment, and quality assurance audit documents. The inspectors evaluated the licensees ability to identify, characterize, prioritize, and resolve identified issues in accordance with PI-AA-204, Condition Identification and Screening Process and PI-AA-205, Condition Evaluation and Corrective Action.
RP program occupational dose assessment guidance and activities were evaluated against the requirements of the UFSAR Chapter 12; TS Sections 6.11; 10 CFR Parts 19 and 20; and approved licensee procedures. Document reviewed are listed in the

2RS5 Radiation Monitoring Instrumentation
a. Inspection Scope
Walkdowns and Observations: During tours of the RAB, turbine deck, SFP areas, control room, and RCA exit points, the inspectors observed installed radiation detection equipment including the following instrument types: area radiation monitors (ARM)s, continuous air monitors, personnel contamination monitors (PCMs) (including hand and foot monitors), small article monitors (SAMs), personnel monitors (PMs), and liquid and gaseous effluent monitors. The inspectors observed the physical location of the components, noted the material condition, noted flow measurement devices, input and output of flow to monitors, and compared sensitivity ranges with UFSAR requirements.
In addition to equipment walkdowns, the inspectors observed source checks and alarm setpoint testing of various portable and fixed detection instruments, including ion chambers, a telepole, GEM-5s, ARGOSTM ABs, and SAMs. Material condition of source check devices, device operation, and establishment of source check acceptance ranges were also discussed with calibration lab personnel.
Calibration and Testing: The inspectors reviewed the last two calibration records for selected ARMs, PCMs, PMs, SAMs, and containment high-range ARMs and the most recent calibration record for a whole body counter. Inspectors reviewed records of survey instrument function/source checks and observed and discussed performance of required checks with calibration lab personnel. Calibration source documentation was reviewed for the ARM high-range calibrator and the Cs-137 (J.L. Shepherd) source used for portable instrument checks. Calibration stickers on portable survey instruments were reviewed and inspections of storage areas for 'ready-to-use' equipment were completed during walkdowns. The inspectors reviewed alarm setpoint values for selected ARMs, PCMs, PMs, SAMs, and effluent monitors. The inspectors also reviewed count room QC records for germanium detectors and liquid scintillator counters.
Problem Identification and Resolution: The inspectors reviewed selected CAP documents in the area of radiological instrumentation. The inspectors evaluated the licensees ability to identify and resolve the issues in accordance with PI-AA-204, Condition Identification and Screening Process and PI-AA-205, Condition Evaluation and Corrective Action.

4OA2 Identification and Resolution of Problems
.1 Daily Review
a. Inspection Scope
As required by Inspection Procedure 71152, Identification and Resolution of Problems, and to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a screening of items entered daily into the licensees CAP. This review was accomplished by reviewing daily printed summaries of action requests and by reviewing the licensees electronic AR database.
Additionally, reactor coolant system unidentified leakage was checked on a daily basis to verify no substantive or unexplained changes.
b. Findings
No findings were identified.
.2 Semi-Annual Trend Review:
a. Inspection Scope
As required by Inspection Procedure 71152, Identification and Resolution of Problems, the inspectors performed a review of the licensees CAP and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors review was focused on repetitive equipment issues, but also considered the results of daily inspector CAP item screening discussed in section 4OA2.1, plant status reviews, plant tours, and licensee trending efforts. The inspectors review nominally considered the six month period of July 2013 through December 2013, although some examples expanded beyond those dates when the scope of the issue warranted. The inspectors evaluated the licensees administration of these selected condition reports in accordance with the CAP as specified in licensee procedures PI-AA-204, Condition Identification and Screening Process, and PI-AA-205, Condition Evaluation and Corrective Action.
b. Findings
No findings were identified.
.3 Annual Sample Review: Unit 1 AFW System Piping Degradation
a. Inspection Scope
The inspectors performed an in-depth review of ARs 1913564 and 1913575 associated with localized corrosion of Unit 1 AFW piping. Non-destructive examination (NDE)performed during the Unit 1 October 2013 RFO SL 1-25 determined that eight localized pipe areas that were previously degraded by corrosion did not meet the required minimum wall thickness criteria. The licensee completed a detailed finite element analysis that showed that the AFW system had remained operable with the degraded pipe. The inspectors reviewed the ARs in detail to determine the circumstances that allowed the AFW system piping to degrade to less than the design criteria. The inspectors verified the licensees actions were in accordance with licensee procedures, PI-AA-204, Condition Reporting and Screening Process, and PI-AA-205, Condition Evaluation and Corrective Actions.
b. Findings and Observations
The inspectors concluded that corrosion of the Unit 1 AFW system has been a longstanding equipment issue that has not been properly addressed. In December 2011, AR 1711863 documented two corrosion cells on the 1C AFW pump discharge piping that were characterized as being more advanced than just minor corrosion. The AR was screened by the operations shift manager as requiring a Mode 3 hold. The Mode 3 hold would ensure the issue was evaluated and resolved prior to restarting the unit. However, administratively, the Mode 3 hold was not put in place and the corroded pipe areas were not fully evaluated prior to restarting the unit. The failure to assign a Mode 3 hold on AR 1711863 was later documented in the CAP as AR 1931323. In September 2012, AR 1808061 was initiated documenting that the rust spots on the 1C AFW piping referenced in AR 1711863 appeared to be further degraded and need to be evaluated. In October 2012, two additional corrosion cells were identified on the same 1C AFW pump discharge piping (AR 1815147). In January 2013, most of the corrosion on the 1C AFW pump discharge piping was removed and engineering personnel measured the depth of the pits in the corroded areas using a pit depth gauge (micrometer). The maximum pit depth found was 0.11 inches. Subtracting 0.11 inches from a nominal wall thickness of 0.337 inches, engineering calculated a pipe wall thickness of 0.227 inches (minimum wall is 0.205 inches). The licensee did not recoat the piping to prevent additional degradation until July 2013. In August 2013, the inspectors identified corrosion on the 1C AFW pump discharge piping to 1A steam generator that had not been previously identified by the licensee (AR 1894701). During the RFO, several localized areas of the degraded AFW pipe documented above were determined to be less than the calculated minimum wall criteria. The regulatory significance of this issue is documented below.
Introduction:
The inspectors identified a Green non-cited violation (NCV) of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, for the licensees failure to identify localized corrosion on the discharge piping for the 1C auxiliary feedwater pump that exceeded the licensees acceptance criteria for minimum pipe wall thickness.
Description:
In August 2013, the inspectors identified an area of localized corrosion on the 1C AFW pump discharge piping to 1A steam generator that had not been previously identified by the licensee in their CAP. In response to the inspectors observations, the licensee entered AR 1894701 into the CAP for further evaluation. Licensee procedure PI-AA-204, Condition Identification and Screening Process, defines, in part, a condition adverse to quality (CAQ) as a deficiency or non-conformance that has the potential to affect the operability or functionality of safety related systems. PI-AA-204, section 4.2, states in part, that the CAP database shall be used to document and track CAQ.
Engineering performed an initial visual examination of the corroded area and determined that the corrosion appeared to be surface corrosion with little or no wastage of metal pipe. This determination was based on the fact that the corrosion cell appeared similar to previously identified corrosion cells that did not exceed the licensees acceptance criteria for minimum wall thickness. A corrective action plan was initiated to inspect and recoat the pipe during the fall 2013 refueling outage (RFO). The licensee completed NDE during the RFO and identified that the localized area had a wall thickness of 0.087 inches that was less than the licensee calculated pipe minimum wall thickness acceptance criteria of 0.205 inches. The licensees minimum wall thickness calculation used the design formulas of ASME Section III and also included the interactions of pressure stress and longitudinal bending stresses. The calculation assumes uniform wall reduction of the pipe run. Localized pipe degradation that exceeds minimum wall thickness may be shown to be acceptable with further analysis to characterize the flaw and its impact on the pipes structural integrity.
During the RFO, ARs 1913564 and 1913575 were initiated by the licensee to address several examples of unsatisfactory NDE results for degraded unit 1 AFW system piping.
The NDEs determined that eight localized pipe areas, including the one identified by the inspector, had wall thicknesses less than the licensees calculated minimum allowed wall thickness. The inspectors reviewed the corrective action program for issues related to AFW piping corrosion and determined that the licensee had opportunities in 2011, 2012, and 2013 to address the corrosion issues. Corrective actions included replacement of several sections of degraded AFW pipe. The licensee also completed a detailed finite element analysis that showed the AFW system would have remained operable with the degraded pipe. The conclusion of the analysis, which only applies to the as-found condition of the degraded AFW piping, showed that the degraded pipe would meet ASME Code allowed minimal wall requirements. Any further degradation would require another detailed evaluation. The licensee also completed a common cause analysis of AFW system equipment issues including problems with corrosion that may result in additional corrective actions.
Analysis:
The licensees failure to identify corrosion on the 1C AFW pump discharge piping that exceeded pipe minimum wall thickness acceptance criteria in the CAP was a performance deficiency. The finding is more than minor because if left uncorrected, the performance deficiency has the potential to lead to a more significant safety concern.
Specifically, unmitigated corrosion of the AFW piping would result in through-wall leaks, affect structural integrity of the piping, and ultimately result in inoperability of the system.
Using Table 2 of Manual Chapter 0609.04, Significance Determination Process (SDP)
Initial Characterization of Findings dated June 19, 2012; the inspectors concluded the finding affected the mitigating systems cornerstone. The inspectors evaluated the finding using IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, dated June 19, 2012. The finding was determined to be of very low safety significance (Green) because all screening questions were answered No. The inspectors determined the cause of this finding was associated with a cross cutting aspect of minimizing longstanding equipment issues in the resources component of the human performance area. Specifically, the licensee had not provided adequate resources to address longstanding Unit 1 AFW system corrosion issues H.2(a)
Enforcement:
Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion XVI, Corrective Action, requires, in part, that measures shall be established to assure that conditions adverse to quality such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected. Licensee procedure PI-AA-204, Condition Identification and Screening Process, defines, in part, a condition adverse to quality as a deficiency or non-conformance that has the potential to affect the operability or functionality of safety related systems. PI-AA-204, section 4.2, states in part, that the CAP database shall be used to document and track condition adverse to quality. Contrary to the above, prior to NRC inspector identification in August 2013, the licensee failed to identify a condition adverse to quality. Specifically, the licensee failed to identify corrosion on the 1C AFW pump discharge piping to 1A steam generator that did not meet the licensees acceptance criteria for minimum wall thickness. Corrective actions taken included replacement of several sections of degraded AFW pipe and a detailed finite element analysis that showed the AFW system would have remained operable with the degraded pipe. Because this finding was of very low safety significance and was entered into the licensees corrective action program as AR 1913575, this violation is being treated as a non-cited violation (NCV) consistent with Section 2.3.2 of the Enforcement Policy: NCV 05000335/2013005-02, Failure to Identify and Implement Appropriate Corrective Actions for AFW System Corrosion.
4OA3 Follow-up of Events and Notice of Enforcement Discretion
Personnel Performance During Unplanned Plant Operations
.1 Unit 1 Manually Tripped Due to Digital Electric-Hydraulic Leak
a. Inspection Scope
On November 12, 2013, Unit 1 was operating at approximately 90 percent RTP when a hydraulic fluid leak developed from a fitting for the digital electrohydraulic (DEH) system associated with the turbine generator. Control room operators initiated a manual reactor trip since the continued loss of hydraulic fluid would result in an automatic turbine trip and a reactor trip.
The inspectors were notified of the reactor trip and responded to the plant to assess plant conditions, determine if any complications occurred during the trip and reactor plant shutdown. The inspectors toured the Unit 1 turbine building and observed Unit 1 control room activities following the shutdown to hot standby. The inspectors reviewed control room chronological logs, control room indications, post trip procedures, and interviewed control room operators to verify that operating restrictions and procedural requirements were met. The inspectors observed control room operator communications, procedure place keeping, and control room annunciator responses by the reactor operators at the control boards. The inspectors reviewed documentation and operator actions associated with licensee procedures 1-EOP-01, Standard Post Trip Actions, and 1-EOP-02, Reactor Trip Recovery. On November 13, the reactor was restarted subsequent to completing DEH system repairs. The inspectors observed the synchronization of the main generator to the electrical grid and portions of the power ascension.
b. Findings
No findings were identified.
.2 Unit 2 Manually Tripped Due to Loss of Feed to B Steam Generator
a. Inspection Scope
On November 14, 2013, Unit 2 was operating at approximately 100 percent RTP when the control room operators noticed a lowering B steam generator water level. The operators initiated a manual reactor trip when the B steam generator water level reached 50 percent as indicated on the narrow range water level instruments. Further reduction of water level to 35 percent would have resulted in an automatic reactor trip.
The inspectors were notified of the reactor trip and responded to the plant to assess plant conditions, determine if any complications occurred during the trip and reactor plant shutdown. The inspector observed Unit 2 control room activities following the shutdown to hot standby. The inspector reviewed control room chronological logs, control room indications, post trip procedures, and interviewed control room operators to verify that operating restrictions and procedural requirements were met. The inspector observed control room operator communications, procedure place keeping, and control room annunciator responses by the reactor operators at the control boards. The inspector reviewed documentation and operator actions associated with licensee procedures 2-EOP-01, Standard Post Trip Actions, and 2-EOP-02, Reactor Trip Recovery. The licensee determined that moisture intrusion into a MFIV relay box caused degradation of the relays that resulted in a B steam generator MFIV closing and lowering steam generator water level. On November 16, the reactor was restarted subsequent to replacement of several relays and sealing of the MFIV relay box. The inspectors observed portions of the restart activities.
b. Findings
No findings were identified.
4OA5 Other Activities
