Effectiveness and Follow-up of Events and Notices of Enforcement Discretion.
This report covered a three-month period of inspection by resident inspectors and announced
inspections performed by regional inspectors. Inspectors identified two findings of very low
safety significance (Green). The significance of most findings is indicated by their color (i.e.,
greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual
Chapter (IMC) 0609, Significance Determination Process, dated June 2, 2011. Cross-cutting
aspects are determined using IMC 0310, Components Within Cross-Cutting Areas, dated
December 19, 2013. All violations of NRC requirements are 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 5.
Cornerstone: Mitigating Systems
  Green. The inspectors identified a finding of very low safety significance (Green) because
    NextEra did not perform adequate evaluations of safety-related residual heat removal
    (RHR) vaults. Specifically, additional technical evaluation and analysis was not adequately
    conducted on the safety-related A and B RHR concrete vaults when it was determined
    that they exceeded the quantitative limits specified in NextEra procedures. NextEra entered
    the failure to perform adequate technical evaluations on concrete structures exceeding
    American Concrete Institute (ACI) Tier II quantitative requirements into the CAP (action
    request (AR) 01929460), and planned to perform a formal technical evaluation of the A
    and B RHR vault conditions in accordance with their structural monitoring program
    procedure and the ACI 349.3R-96 standard.
    The performance deficiency was considered to be more than minor because it affected the
    protection against external factors attribute of the Mitigating Systems cornerstone and its
    objective to ensure the availability, reliability, and capability of systems that respond to
    initiating events to prevent undesirable consequences. Specifically, the inspectors
    concluded that the reliability of the structures was affected in that they exceeded the
    specified Tier II limits without the performance of further technical evaluations. The issue
    was evaluated in accordance with IMC 0609, Appendix A, The Significance Determination
    Process for Findings At-Power, and determined to be of very low safety significance
    (Green) because it did not represent an actual loss of function of at least a single train for
    greater than its Technical Specification Allowed Outage Time or two separate safety
    systems out-of-service for greater than it Technical Specification Allowed Outage Time.
    This finding is related to the cross-cutting area of Human Performance - Procedure
    Adherence, because NextEra did not follow processes, procedures, and work instructions.
    Specifically, NextEra personnel did not perform an adequate technical evaluation of two
    safety-related concrete structures that exceeded the quantitative criteria requiring such an
    evaluation [H.8]. (Section 1R12)
  Green. The inspectors identified a self-revealing finding of very low safety significance
    (Green), because NextEra did not ensure that adequate procedural guidance existed in
    ON1046.12, Operation of the Main Generator Breaker to limit the likelihood of events that
    upset plant stability. Specifically, Seabrook station experienced an automatic reactor trip
    from approximately 15 percent reactor power on April 1, 2014 when two of four reactor
                                                                                            Enclosure
 
                                                  4
  coolant pumps (RCPs) tripped on low bus voltage. The cause of the reactor trip was
  directly attributable to the main generator breaker inadvertently closing and actuating the
  main generator multi-function protective relay. NextEra entered the event into their CAP,
  and conducted a root cause evaluation to determine the root and contributing causes,
  extent of condition and extent of cause, and to identify corrective actions to prevent
  recurrence. NextEra initiated actions to revise ON1046.12 to add controls regarding the
  potential risk associated with placing the main generator breaker control in local, conducted
  briefings with Maintenance groups involved in the event, and evaluated the adequacy of
  other Operations procedures that place equipment in a configuration where protective
  features are bypassed or defeated.
  The performance deficiency was more than minor because it was associated with the
  procedure quality attribute of the Initiating Events cornerstone, and it adversely affected the
  cornerstone objective to limit the likelihood of events that upset plant stability and challenge
  critical safety functions during shutdown as well as power operations. The finding was
  evaluated under IMC 0609, Attachment 4, Phase 1 - Initial Characterization of Findings.
  The inspectors determined that the finding is of very low safety significance (Green)
  because it did not result in both a reactor trip and the loss of mitigating equipment relied
  upon to transition the plant from the onset of the trip to a stable shutdown condition. The
  finding has a cross-cutting aspect in the area of Human Performance - Work Management,
  because NextEra did not ensure that a process of planning, controlling, and executing work
  activities such that nuclear safety is the overriding priority was implemented. Specifically,
  ON1046.12, Operation of the Main Generator Breaker did not contain adequate
  procedural guidance regarding the impacts of positioning the Main Generator Selector
  Switch to local, take mitigating actions, and minimize time spent at increased risk
  configurations [H.5]. (Section 4OA3)
Other Findings
  A violation of very low safety significance that was identified by NextEra was reviewed by
  the inspectors. Corrective actions taken or planned by NextEra have been entered into
  NextEras corrective action program. This violation and corrective action tracking number
  are listed in Section 4OA7 of this report.

                                        REPORT DETAILS
Summary of Plant Status
Seabrook Unit 1 began the assessment period reducing power to begin a planned refueling
outage (OR) 16. However, at 12:26 a.m., on April 1, 2014, an unanticipated reactor trip
occurred while the plant was at approximately 15 percent reactor power. Following the reactor
trip, Unit 1 remained shutdown until April 24, 2014 when the main unit generator was
successfully synchronized with offsite power, and resumed full power operation (100 percent)
on April 28, 2014. Seabrook Unit 1 operated at essentially 100 percent power for the remainder
of the assessment period. Documents reviewed for each section of this inspection report are
listed in the Attachment.
1.      REACTOR SAFETY
        Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity
1R01 Adverse Weather Protection (71111.01 - 3 samples)
.1      Readiness for Seasonal Extreme Weather Conditions
    a. Inspection Scope
        The inspectors performed a review of NextEras readiness for the onset of seasonal high
        temperatures. The review focused on the service water cooling tower, service water
        pump house, switchyard, termination yard, and the control building. The inspectors
        reviewed the Updated Final Safety Analysis Report (UFSAR), technical specifications
        (TSs), the seasonal readiness memorandum, and the corrective action program to
        determine specific temperatures or other seasonal weather that could challenge these
        systems, and to ensure NextEra personnel had adequately prepared for these
        challenges. The inspectors reviewed station procedures, including NextEras seasonal
        weather preparation procedure and applicable operating procedures. The inspectors
        performed walkdowns of the selected systems to ensure station personnel identified
        issues that could challenge the operability of the systems during hot weather conditions.
    b. Findings
        No findings were identified.
.2      Summer Readiness of Offsite and Alternate Alternating Current (AC) Power Systems
    a. Inspection Scope
        The inspectors performed a review of plant features and procedures for the operation
        and continued availability of the offsite and alternate AC power system to evaluate
        readiness of the systems prior to seasonal high grid loading. The inspectors reviewed
        NextEras procedures affecting these areas and the communication protocols between
        the transmission system operator and NextEra. This review focused on changes to the
        established program and material condition of the offsite and alternate AC power
        equipment. The inspectors assessed whether NextEra established and implemented
        appropriate procedures and protocols to monitor and maintain availability and reliability
                                                                                          Enclosure
 
                                                6
      of both the offsite AC power system and the onsite alternate AC power system. The
      inspectors evaluated the material condition of the associated equipment by interviewing
      the responsible system manager, reviewing condition reports (CRs) and open work
      orders, and walking down portions of the offsite and AC power systems including the
      345 kilovolt (kV) termination yard, the 345 kV switchyard, and the relay room.
  b. Findings
      No findings were identified.
.3    External Flooding
  a. Inspection Scope
      During the period of June 16 to June 20, 2014, the inspectors performed an inspection of
      the external flood protection measures for Seabrook Station. The inspectors reviewed
      the Updated Final Safety Analysis Report (UFSAR), Chapter 2.4.2.2, which depicts the
      design flood levels and protection areas containing safety-related equipment to identify
      areas that may be affected by external flooding. The inspectors conducted a general
      site walkdown of the outside area of the site, fuel storage building, the control building,
      and the emergency diesel generator building to ensure that NextEra erected flood
      protection measures in accordance with design specifications. The inspectors also
      reviewed operating procedures for mitigating external flooding during severe weather to
      determine if NextEra planned or established adequate measures to protect against
      external flooding events.
  b. Findings
      No findings were identified.
1R04 Equipment Alignment
.1    Partial System Walkdowns (71111.04Q - 4 samples)
  a. Inspection Scope
      The inspectors performed partial walkdowns of the following systems:
        Containment penetration return to service on April 17, 2014
        'A' residual heal removal (RHR) return to service on April 23, 2014
        B' emergency feedwater (EFW) pump return to service on June 19, 2014
        'B' service water return to service on June 26, 2014
      The inspectors selected these systems based on their risk-significance relative to the
      reactor safety cornerstones at the time they were inspected. The inspectors reviewed
      applicable operating procedures, system diagrams, the UFSAR, TSs, work orders
      (WOs), CRs, and the impact of ongoing work activities on redundant trains of equipment
      in order to identify conditions that could have impacted system performance of their
      intended safety functions. The inspectors also performed field walkdowns of accessible
      portions of the systems to verify system components and support equipment were
                                                                                        Enclosure
 
                                                7
      aligned correctly and were operable. The inspectors examined the material condition of
      the components and observed operating parameters of equipment to verify that there
      were no deficiencies. The inspectors also reviewed whether NextEra staff had properly
      identified equipment issues and entered them into the corrective action program (CAP)
      for resolution with the appropriate significance characterization.
  b. Findings
      No findings were identified.
.2    Full System Walkdown (71111.04S - 1 sample)
  a. Inspection Scope
      On April 17, 2014, the inspectors performed a complete system walkdown of accessible
      portions of the service water system to verify the existing equipment lineup was correct.
      The inspectors reviewed operating procedures, surveillance tests, drawings, equipment
      line-up check-off lists, and the UFSAR to verify the system was aligned to perform its
      required safety functions. The inspectors also reviewed electrical power availability,
      component lubrication and equipment cooling, hanger and support functionality, and
      operability of support systems. The inspectors performed field walkdowns of accessible
      portions of the systems to verify system components and support equipment were
      aligned correctly and operable. The inspectors examined the material condition of the
      components and observed operating parameters of equipment to verify that there were
      no deficiencies. Additionally, the inspectors reviewed a sample of related CRs and work
      orders to ensure NextEra appropriately evaluated and resolved any deficiencies.
  b. Findings
      No findings were identified.
1R05 Fire Protection
.1    Resident Inspector Quarterly Walkdowns (71111.05Q - 5 samples)
  a. Inspection Scope
      The inspectors conducted tours of the areas listed below to assess the material
      condition and operational status of fire protection features. The inspectors verified that
      NextEra controlled combustible materials and ignition sources in accordance with
      administrative procedures. The inspectors verified that fire protection and suppression
      equipment was available for use as specified in the area pre-fire plan, and passive fire
      barriers were maintained in good material condition. The inspectors also verified that
      station personnel implemented compensatory measures for out of service (OOS),
      degraded, or inoperable fire protection equipment, as applicable, in accordance with
      procedures.
          Containment Building C-F-1-Z, C-F-2-Z, & C-F-3-Z on April 7, 2014

.2    Fire Protection - Fire Brigade Response on April 16, 2014 (71111.05A - 1 sample)
  a. Inspection Scope
      The inspectors observed and evaluated control room operator and fire brigade response
      to fire alarms within containment on April 16, 2014, that involved flames, sparks, and
      smoke associated with the terminal box for the A reactor coolant pump. The inspectors
      verified that NextEra personnel identified deficiencies and took appropriate corrective
      actions as required. The inspectors evaluated specific attributes as follows:
          Proper wearing of turnout gear and self-contained breathing apparatus
          Sufficient fire-fighting equipment brought to the scene
          Effectiveness of command and control
          Communications established between fire brigade and control room
          Propagation of the fire into other plant areas
          Smoke removal operations
          Utilization of pre-planned strategies
          Procedure adherence regarding fire alarm response, fire brigade dispatch, fire alarm
          activation, containment evacuation alarm initiation, and assessment of emergency
          plan actions
  b. Findings
      No findings were identified.
1R06 Flood Protection Measures (71111.06 - 2 samples)
.1    Internal Flooding Review
  a. Inspection Scope
      The inspectors reviewed the UFSAR, the site flooding analysis, and plant procedures to
      assess susceptibilities involving internal flooding. The inspectors also reviewed the CAP
      to determine if NextEra identified and corrected flooding problems and whether operator
      actions for coping with flooding were adequate. The inspectors also focused on the
      control building to verify the adequacy of equipment seals located below the flood line,
      floor and water penetration seals, watertight door seals, common drain lines and sumps,
      sump pumps, level alarms, control circuits, and temporary or removable flood barriers.
  b. Findings
      No findings were identified.
                                                                                        Enclosure
 
                                                9
.2    Annual Review of Cables Located in Underground Bunkers/Manholes
  a. Inspection Scope
      The inspectors conducted an inspection of two samples of underground
      bunkers/manholes subject to flooding that contain cables whose failure could affect risk-
      significant equipment. The inspectors performed walkdowns of risk-significant areas,
      specifically manholes No. 5 and No. 11, which contain safety-related cables routed to
      the service water pumphouse from essential switchgear. The inspectors verified water
      level in the sump/manhole to ensure that the cables were not submerged. The
      inspectors verified that the bunkers/manholes were dewatered in accordance with
      station procedures.
  b. Findings
      No findings were identified.
1R07 Heat Sink Performance (71111.07A - 1 sample)
  a. Inspection Scope
      The inspectors reviewed the B emergency diesel generator (EDG) jacket water heat
      exchanger to determine its readiness and availability to perform its safety functions.
      The inspectors reviewed the design basis for the component and verified NextEras
      commitments to NRC Generic Letter 89-13. The inspectors observed actual
      performance tests for the heat exchangers and/or reviewed the results of previous
      inspections of the B EDG jacket water and similar heat exchangers. The inspectors
      discussed the results of the most recent inspection with engineering staff and reviewed
      pictures of the as-found and as-left conditions. The inspectors verified that NextEra
      initiated appropriate corrective actions for identified deficiencies. The inspectors also
      verified that the number of tubes plugged within the heat exchanger did not exceed the
      maximum amount allowed.
  b. Findings
      No findings were identified.
1R08 In-service Inspection (71111.08 - 1 sample)
  a. Inspection Scope
      From April 4 to April 11, 2014 and from April 13 to April 16, 2014, the inspectors
      conducted a review of NextEras implementation of in-service inspection (ISI) program
      activities for Seabrook Unit 1. These activities monitor the reactor coolant system
      pressure boundary, risk significant piping and components and the containment to
      identify degradation, complete evaluations and make repairs or replacements as
      required. Sample selection was based on the inspection procedure objectives and risk
      priority of those pressure retaining components in systems where degradation could
      result in a significant increase in risk. The inspectors observed in-process non-

as part of Period 2 of the third 10-year interval of the Seabrook ISI Program, during
refueling outage OR16, were conducted in accordance with the requirements of the
ASME Boiler and Pressure Vessel Code Section XI, 2004 Edition, No Addenda.
Nondestructive Examination (NDE) and Welding Activities
ASME Code-Required Examinations
The inspectors reviewed the equipment calibration sheet and the inspection data sheets
from the ultrasonic testing (UT) examination of the pressurizer nozzle inner radius weld
(RC E 10 A IR). There were no recordable indications from this examination and 100
percent coverage was achieved.
The inspectors reviewed the equipment calibration sheet and inspection data sheets
from the UT examination of the pressurizer nozzle weld (RC E-10 A-NZ). There were no
recordable indications from this examination; however coverage was limited to 74
percent due to the nozzle configuration.
The inspectors reviewed the equipment calibration sheet and the inspection data sheets
from the UT examination of the Steam Generator (SG) A nozzle to pipe weld (RC E
11A 2B NZ). There were no recordable indications from this examination and 100
percent coverage was achieved.
The inspectors reviewed the equipment calibration sheet and inspection data sheets
from the UT examination of the pressurizer nozzle weld (RC E-10 2A-NZ). There were
no recordable indications from this examination; however coverage was limited to 98
percent due to the nozzle configuration.
The inspectors reviewed the equipment calibration sheet and the inspection data sheets
from the UT examination of the SG A pipe to nozzle weld inner radius (RC E 11 2A-IR).
There were no recordable indications from this examination and 100 percent coverage
was achieved.
The inspectors reviewed the equipment calibration sheet and the inspection data sheets
from the UT examination of the SG A nozzle to pipe weld inner radius (RC E-11A 2B
IR). There were no recordable indications from this examination and 98 percent
coverage was achieved.
The inspectors reviewed the equipment calibration sheets and the inspection data
sheets from the UT examination of the pressurizer nozzle weld (RC E-11 2B-NZ). There
were no recordable indications from this examination and 98 percent coverage was
achieved.
The inspectors reviewed the inspection data sheet from the bare metal visual
examination of the reactor vessel closure head (RVCH) and control rod drive mechanism
(CRDM) nozzle penetrations performed in accordance with ASME Code Case 792-1.
The inspectors reviewed certifications of the NDE technicians performing these
examinations and verified that the inspections were performed in accordance with
approved procedures and that the results were reviewed and evaluated by certified
Level III NDE personnel.

                                          11
Other Containment Liner Examinations
The inspectors reviewed additional UT results completed by NextEra to examine the
containment liner. NextEra performed ultrasonic thickness measurements of 51, one-
square foot area sample locations of the containment liner. These measurements were
taken from the inside of the containment at elevation -26 feet and were spaced
approximately every 6 degrees in azimuth around the containment circumference in
accessible areas. The containment liner thicknesses were measured to be nominally
0.375 inch in thickness at all locations, and no exterior or interior surface degradation of
the liner was evident.
The inspectors reviewed the visual testing (VT) procedures and the recorded inspection
results for the inspection of an anomaly on the upper dome portion of the containment
liner. The inspectors determined these inspections were conducted in accordance with
the ASME Code Section XI, Subsection IWE. An engineering evaluation of the
inspection results concluded that no observable change had occurred in the anomaly
and recommended re-inspection during the next refueling outage, OR17.
The inspectors reviewed the records of a water intrusion condition in the fuel transfer
tube vault which had been identified in 2009. One wall of the fuel transfer tube vault is
also part of the containment liner. In April 2011, NextEra staff made an entry into the
vault area and conducted an inspection of the liner condition inside the vault. Some
areas of the containment liner portion of the fuel tube vault had minor, light rust which
was removed. UT measurements of the liner thickness in 2011 verified that all
previously rusted areas on the liner were greater than 0.375 inch. Also, NextEra staff
made repairs to the non-liner portion of the vault wall which had shown signs of leakage.
Because this repair was not on the containment liner portion of the vault, no repair has
been made under the ASME Code, Section IWE in the fuel transfer vault. The
inspectors determined there were no examinations completed during OR16. An
examination was not required because the leak was stopped in 2011 and a repair was
not made to the containment liner.
Review of Originally Rejectable Indications Accepted by Evaluation
The inspectors reviewed a volumetric examination data sheet for an indication identified
during a previous (OR15) inspection of a piping weld in line SI- 0251-07-09. A flaw
evaluation completed by a qualified NDE Level III individual later determined that the
flaw was acceptable per ASME Code, Subsection XI, Table IWB-3514-2.
The inspectors reviewed the NDE report of a weld flaw detected in the J-groove weld
during the ultrasonic (UT) examination of RVCH penetration No. 57. These inspections
are required by 10 CFR 50.55(a) and Code Case N-729-1. NextEra staff performed a
manual eddy current (EC) inspection to determine if the indication was fully contained
within the weld. The EC exam showed that the indication was completely contained by
the weld material and was acceptable per the requirements of the ASME Code without
repair.
Repair/Replacement Activities
The inspectors reviewed WO package 40108170-01 for replacement and testing
activities of pressure relief valve SI-V-60, the D accumulator relief valve. The
inspectors verified that the replacement valve was successfully tested with a leak test
                                                                                    Enclosure
 
                                          12
pressure of 630.5 psig. The inspectors also reviewed the VT-2 visual examination data
sheet for SI-V-60, and the Form A of the Flanged Joint Torque Traveler for the valve.
The inspectors also reviewed the Field Work Closeout Form and the ASME Form NIS-
2A Repair/Replacement Certification Record. The inspectors determined that the
replacement was completed in accordance with ASME Section XI, Repair/Replacement
requirements.
The inspectors reviewed WO 40220458-03 associated with the shop fabrication of piping
to replace the service water pump P-41 B/D discharge piping with AL6XN piping material
per engineering change EC278717. The inspectors reviewed the ASME Section XI
Repair/Replacement Plan Traveler, the Form A Weld Traveler, and the liquid penetrant
test records to verify that the replacement piping had been fabricated in accordance with
the change document. The inspectors verified that the Repair/Replacement Plan had
been completed correctly in accordance with the ASME Section XI Code.
PWR Vessel Upper Head Penetration (VUHP) Inspection Activities
The inspectors reviewed the NextEra calculations of Effective Degradation Years (EDY)
and Re-inspection Year (RIY) for the Seabrook Unit 1 Reactor Vessel Upper Head
completed prior to OR16. Based on these calculation results, NextEra completed an
inspection of the Unit 1 VUHP J-groove welds during the OR16 refueling outage.
These calculations were performed in accordance with the requirements of 10 CFR
50.55a(g)(6)(ii)(D) and the ASME Boiler and Pressure Vessel Code Case N 729 1,
Alternative Examination Requirements for PWR Reactor Vessel Upper Heads, to
ensure the structural integrity of the reactor vessel head pressure boundary.
The inspectors reviewed visual inspection reports (Data Sheets) of the remote bare
metal visual examination of the exterior surface of Unit 1 VUHP to confirm appropriate
inspection coverage was achieved and to verify that no boric acid leakage or wastage
had occurred.
The inspectors observed the ultrasonic examination of several RVCH penetrations and
reviewed the data from the inspection of penetration No. 57 which identified a recordable
indication in the J-groove weld. The inspectors reviewed the Eddy Current (ET)
inspection data used to verify the location of the indication. This inspection verified that
the indication was enclosed within the J-groove weld and could be accepted for
continued use without repair. There were no other recordable indications detected in the
other reactor vessel upper head nozzle penetrations.
Boric Acid Corrosion Control (BACC) Inspection Activities
The inspectors reviewed the boric acid corrosion control program, which is conducted
in accordance with Seabrook Unit 1 Station procedures and NextEra procedures,
discussed the program with the boric acid program owner, and sampled photographic
inspection records of boric acid leaks found on safety significant piping and components
inside the Seabrook Unit 1 containment. The walkdowns were conducted by NextEra
personnel and were directly observed by the NRC Resident Inspectors on April 1, 2014,
during the initial containment entry for the OR16 outage. The inspectors reviewed a
sample of leaks observed and reported, the identification and documentation of non-
conforming conditions identified in the corrective action program and reviewed a sample
of boric acid evaluations completed by engineering to repair or monitor the conditions.

                                          13
The inspectors verified that potential deficiencies identified during the walkdowns were
entered into NextEras corrective action program and reviewed a sample of engineering
evaluations of the conditions reported to verify that the corrective actions were
consistent with the requirements of the NextEra procedures and 10 CFR 50, Appendix
B, Criterion XVI.
Steam Generator (SG) Tube Inspection Activities
The inspectors observed a portion of SG eddy current testing (ECT) examinations, data
evaluation, and documentation review of the final list of pluggable tubes from this
inspection.
The inspectors remotely observed a sample of the Unit 1 SG eddy current tube
examinations which were based upon Seabrook's operating experience and the
assessment of past degradation mechanisms.
The scope consisted of the following examinations:
  100 percent bobbin coil probe examination of SG 'B'
  20 percent bobbin coil probe examination of SG 'A', SG 'C', and SG 'D', including
    Outside Diameter Stress Corrosion Cracking (ODSCC) susceptible tubes, and tubes
    susceptible to tube-to-tube wear
  100 percent +Point examination of dings/dents > 5 volts on HL (including U-Bend)
    in SG 'C'
  20 percent +Point examination of dings/dents > 5 volts on HL (including U-bend)
    in SG 'A', SG 'B', and SG 'D'
  Resolution of all bobbin coil probe "I" codes
  Visual inspection of all plugs (mechanical and welded)
  Visual inspection of channel heads in all SG's
The inspectors reviewed a sample of the indications identified in the SGs during the
OR15 eddy current inspections to verify that they were consistent with the potential
degradation mechanisms that may be observed during the current OR16 inspections
as documented in SG-SGMP-13-21, Revision 3, Steam Generator Degradation
Assessment for the Seabrook OR16 Refueling Outage. The inspectors also reviewed
the Condition Monitoring and Operational Assessments from the prior outage, OR15.
The inspectors verified that the SG eddy current tube examinations were performed
in accordance with Unit 1 Technical Specifications and the Unit 1 Steam Generator
Program by reviewing the SG tube eddy current test results to verify that no in-situ
pressure testing was required, no tubes required stabilization, and no increased primary-
to-secondary leakage had occurred over the operating cycle.
The inspector also verified that the tubes that exhibited degradation and did not meet
acceptance criteria were plugged (3 tubes, due to anti-vibration bar wear) or sleeved (0
tubes) using the alternate repair criteria per Generic Letter 95-05, Voltage-Based Repair
Criteria for Westinghouse Steam Generator Tubes Affected by ODSCC during the OR16
inspection.

                                              14
      The inspectors verified that SG tubes that exhibited degradation examination screening
      criteria was in accordance with the Electric Power Research Institute (EPRI) Steam
      Generator Guidelines and flaw sizing was in accordance with EPRI examination
      technique specification sheet. During OR16, NextEra plugged three tubes in C SG due
      to anti-vibration bar wear. The total tubes plugged in all four SG's, at the completion of
      OR16, was 185.
      NextEra staff did not conduct foreign object search and retrieval (FOSAR) on the
      secondary side of the SGs during OR16, because the secondary side of the SG's were
      not opened and inspected during this outage.
      The inspectors reviewed the Westinghouse eddy current testing procedures and verified
      that NextEra completed the steam generator inspections in accordance with the
      requirements of NEI 97-06, Pressurized Water Reactor Steam Generator Examination
      Guidelines, Revision 7. The inspectors also reviewed the Westinghouse procedure
      qualification certifications and a sample of data analysts' personnel certifications. The
      inspectors reviewed a sample of eddy current qualification records for Primary and
      Secondary resolution analysts, Independent Quality Data Analysts, and Utility Level III
      Quality Data Analysts.
      Identification and Resolution of Problems
      The inspectors reviewed a sample of Seabrook Station Unit 1 condition reports, which
      identified NDE indications, deficiencies and other non-conforming conditions since the
      previous OR15 outage and during the current OR16 outage. The inspectors verified that
      nonconforming conditions were properly identified, characterized, evaluated and entered
      into the corrective action program.
  b. Findings
      No findings were identified.

.1    Quarterly Review of Licensed Operator Requalification Testing and Training
  a. Inspection Scope
      The inspectors observed licensed operator simulator training on June 25, 2014, which
      included a loss of coolant accident coincident with a loss of off-site power. The
      inspectors evaluated operator performance during the simulated event and verified
      completion of risk significant operator actions, including the use of abnormal and
      emergency operating procedures. The inspectors assessed the clarity and effectiveness
      of communications, implementation of actions in response to alarms and degrading plant
      conditions, and the oversight and direction provided by the control room supervisor. The
      inspectors verified the accuracy and timeliness of the emergency classification made by
      the shift manager and the TS action statements entered by the shift technical
      advisor. Additionally, the inspectors assessed the ability of the crew and training staff to
      identify and document crew performance problems.

.2    Quarterly Review of Licensed Operator Performance in the Main Control Room
  a. Inspection Scope
      The inspectors observed licensed operator performance in the main control room during
      plant shutdown in preparation for a planned refueling outage (OR16), and observed
      operations staff event response to a reactor trip and transition to Mode 3 on April 1,
      2014. Additionally, inspectors observed containment fire response on April 16, 2014;
      initial reactor coolant system (RCS) draindown and heatup activities on April 4 and 21,
      2014; approach to criticality and transition to Mode 2 on April 23, 2014; control room
      turnover on June 10, 2014; and RCS boration and turbine control system reboot on
      June 12, 2014. The inspectors observed applicable test performance to verify that
      procedure use, crew communications, and coordination of activities between work
      groups similarly met established expectations and standards.
  b. Findings
      No findings were identified.
1R12 Maintenance Effectiveness (71111.12 - 2 samples)
  a. Inspection Scope
      The inspectors reviewed the samples listed below to assess the effectiveness of
      maintenance activities on structure, system, and component (SSC) performance and
      reliability. The inspectors reviewed system health reports, CAP documents,
      maintenance WOs, and maintenance rule (MR) basis documents to ensure that
      NextEra was identifying and properly evaluating performance problems within the scope
      of the MR. For each sample selected, the inspectors verified that the SSC was properly
      scoped into the MR in accordance with 10 CFR 50.65 and verified that the (a)(2)
      performance criteria established by NextEra staff was reasonable. As applicable, for
      SSCs classified as (a)(1), the inspectors assessed the adequacy of goals and corrective
      actions to return these SSCs to (a)(2). Additionally, the inspectors ensured that NextEra
      staff was identifying and addressing common cause failures that occurred within and
      across MR system boundaries.

          Structures monitoring program - RHR vaults on May 23, 2014
  b. Findings
      Introduction: The inspectors identified a finding of very low safety significance (Green)
      because NextEra did not perform adequate evaluations of safety-related RHR vaults.
      Specifically, additional technical evaluation and analysis was not adequately conducted
      on the safety-related A and B RHR concrete vaults when it was determined that they
      exceeded the quantitative limits specified in NextEra procedures.

Description: NextEras Engineering Department Standard 36180, Structural Monitoring
Program provides guidance for the conduct of the structural condition monitoring
program to meet the requirements of 10CFR 50.65, the Maintenance Rule. The
procedure provides a systematic approach for evaluation of plant structures to provide
reasonable assurance that those structures are capable of fulfilling their intended safety
function. This is accomplished, in part, by periodic reviews of the condition of plant
structures via systematic walkdowns. Additionally, NextEras structural monitoring
program commits to the requirements specified in the American Concrete Institute
standard ACI 349.3R-96, Evaluation of Existing Nuclear Safety Related Concrete
Structures for the evaluation of conditions identified in safety-related concrete
structures. This commitment was formally implemented by procedure revision on
July 29, 2013.
NextEras structural monitoring program procedure states that measurable
discontinuities exceeding specified ACI Tier II quantitative limits shall be considered
unacceptable and in need of further technical evaluation and that further evaluation
should consider the use of other inspection, testing or analytical tools to obtain condition
and functional information of the structures in question.
While performing a plant walkdown on May 23, 2014, the inspectors identified several
instances of concrete conditions in the A and B RHR vaults that exceeded the
quantitative Tier II criteria specified in NextEras procedure. These conditions included:
spalling greater than 20 millimeter (mm) in depth, passive cracks greater than 1 mm,
and staining of an undefined source on concrete surfaces. The load bearing walls of
the RHR vaults are approximately 30 inches thick and are reinforced with number
8 vertical reinforcing bars spaced at 12 inches each face and number 9 horizontal
reinforcing bars spaced at 9 inches each face.
The inspectors reviewed NextEras routine structures monitoring program walkdown
evaluations conducted on the A RHR vault on October 10, 2013 and the B RHR vault
on March 25, 2014. The inspectors noted that NextEra personnel had identified the
conditions, but had not conducted adequate technical evaluation of those conditions.
Specifically, NextEras analysis of the conditions in the RHR vaults relied largely on
engineering judgment and did not use any other inspection, testing or analytical tools to
obtain additional condition and functional information of the two vaults.
The inspectors consulted with regional specialists, reviewed a subsequent licensee
evaluation of the RHR vaults, and concluded that the RHR vaults remain operable and
have reasonable assurance of structural integrity. This conclusion is based on the
significant reduction in crack width below the concrete cover, and the absence of
degradation or distress in the concrete surrounding the cracks. The observed cracks
do not show any indications that they are alkali-silica reaction (ASR) related/induced
cracks Rather, the cracking is more likely due to shrinkage and/or settlement-induced
stress relief. Additional engineering review and analysis is warranted to more clearly
identify and understand the cause(s) of the observed cracking in the RHR vaults.
NextEra entered the failure to perform adequate technical evaluations on concrete
structures exceeding Tier II quantitative requirements into the Corrective Action Program
(AR 01929460), and planned to perform a formal technical evaluation of the A and B
RHR vault conditions in accordance with their structural monitoring program procedure
and the ACI 349.3R-96 standard.

                                                  17
      Analysis: The inspectors determined that NextEras failure to perform an adequate
      technical evaluation of conditions identified in the A and B RHR vaults that exceeded
      the Tier II quantitative criteria in the structures monitoring program procedure was a
      performance deficiency within NextEras ability to foresee and correct. The performance
      deficiency was considered to be more than minor because it affected the protection
      against external factors attribute of the Mitigating Systems cornerstone and its objective
      to ensure the availability, reliability, and capability of systems that respond to initiating
      events to prevent undesirable consequences. Specifically, the inspectors concluded that
      the reliability of the structures was affected in that they exceeded the specified Tier II
      limits without the performance of further technical evaluations. The issue was evaluated
      in accordance with IMC 0609, Appendix A, The Significance Determination Process
      for Findings At-Power, and determined to be of very low safety significance (Green)
      because it did not represent an actual loss of function of at least a single train for greater
      than its TS Allowed Outage Time or two separate safety systems out-of-service for
      greater than its TS Allowed Outage Time. This finding is related to the cross-cutting
      area of Human Performance - Procedure Adherence, because NextEra did not follow
      processes, procedures, and work instructions. Specifically, NextEra personnel did not
      perform an adequate technical evaluation of two safety-related concrete structures that
      exceeded the quantitative criteria requiring such an evaluation [H.8].
      Enforcement: Enforcement action does not apply because the performance deficiency
      did not involve a violation of a regulatory requirement. (FIN 05000443/2014003-01,
      Inadequate Technical Evaluation of Safety-Related Structures)
1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13 - 6 samples)
  a. Inspection Scope
      The inspectors reviewed station evaluation and management of plant risk for the
      maintenance and emergent work activities listed below to verify that NextEra performed
      the appropriate risk assessments prior to removing equipment for work. The inspectors
      selected these activities based on potential risk significance relative to the reactor safety
      cornerstones. As applicable for each activity, the inspectors verified that NextEra
      personnel performed risk assessments as required by 10 CFR 50.65(a)(4) and that the
      assessments were accurate and complete. When NextEra performed emergent work,
      the inspectors verified that operations personnel promptly assessed and managed plant
      risk. The inspectors reviewed the scope of maintenance work and discussed the results
      of the assessment with the stations probabilistic risk analyst to verify plant conditions
      were consistent with the risk assessment. The inspectors also reviewed the TS
      requirements and inspected portions of redundant safety systems, when applicable, to
      verify risk analysis assumptions were valid and applicable requirements were met.

1R15 Operability Determinations and Functionality Assessments (71111.15 - 4 samples)
  a. Inspection Scope
      The inspectors reviewed operability determinations for the following degraded or non-
      conforming conditions:
          A EFW past operability due to oil leak identified on March 19, 2014
          Vital inverter EDE-1B increased DC input amps on May 25, 2014
          RCP undervoltage (UV) time delay relays out of tolerance on June 9, 2014
          Seat leakage on 1-MS-V-393 on June 19, 2014
      The inspectors selected these issues based on the risk significance of the associated
      components and systems. The inspectors evaluated the technical adequacy of the
      operability determinations to assess whether TS operability was properly justified and
      the subject component or system remained available such that no unrecognized
      increase in risk occurred. The inspectors compared the operability and design criteria
      in the appropriate sections of the TSs and UFSAR to NextEras evaluations to determine
      whether the components or systems were operable. Where compensatory measures
      were required to maintain operability, the inspectors determined whether the measures
      in place would function as intended and were properly controlled by NextEra. The
      inspectors determined, where appropriate, compliance with bounding limitations
      associated with the evaluations.
  b. Findings
      No findings were identified.
1R18 Plant Modifications (71111.18 - 1 sample)
      Temporary Modifications
  a. Inspection Scope
      The inspectors reviewed the temporary modifications listed below to determine whether
      the modifications affected the safety functions of systems that are important to safety.
      The inspectors reviewed 10 CFR 50.59 documentation and post-modification testing
      results, and conducted field walkdowns of the modifications to verify that the temporary
      modifications did not degrade the design bases, licensing bases, and performance
      capability of the affected systems. In addition, the inspectors reviewed modification
      documents associated with the upgrade, including associated engineering changes,
      correspondence with the vendor, industry operating experience, environmental and
      seismic qualifications, as well as the 10 CFR 50.59 documentation and post-modification
      testing results, as applicable.

  a. Inspection Scope
      The inspectors reviewed the post-maintenance tests for the maintenance activities
      listed below to verify that procedures and test activities ensured system operability
      and functional capability. The inspectors reviewed the test procedure to verify that the
      procedure adequately tested the safety functions that may have been affected by the
      maintenance activity, that the acceptance criteria in the procedure was consistent with
      the information in the applicable licensing basis and/or design basis documents, and
      that the procedure had been properly reviewed and approved. The inspectors also
      witnessed the test or reviewed test data to verify that the test results adequately
      demonstrated restoration of the affected safety functions.

1R20 Refueling and Other Outage Activities (71111.20 - 1 sample)
  a. Inspection Scope
      The inspectors reviewed the stations work schedule and outage risk plan for the
      maintenance and refueling outage (OR16), which was conducted April 1 to 22, 2014.
      The inspectors reviewed NextEras development and implementation of outage plans
      and schedules to verify that risk, industry experience, previous site-specific problems,
      and defense-in-depth were considered. During the outage, the inspectors observed
      and evaluated the following outage activities:
          Shutdown and cooldown operations, and transition to Mode 5 and entry into RHR
          operations
          Configuration management, including maintenance of defense-in-depth,

1R22 Surveillance Testing (71111.22 - 9 samples)
  a. Inspection Scope
      The inspectors observed performance of surveillance tests and/or reviewed test data of
      selected risk-significant SSCs to assess whether test results satisfied TSs, the UFSAR,
      and NextEra procedure requirements. The inspectors verified that test acceptance
      criteria were clear, tests demonstrated operational readiness and were consistent with
      design documentation, test instrumentation had current calibrations and the range and
      accuracy for the application, tests were performed as written, and applicable test
      prerequisites were satisfied. Upon test completion, the inspectors considered whether

2.    RADIATION SAFETY
      Cornerstone: Occupational Radiation Safety
2RS1 Radiological Hazard Assessment and Exposure Controls (71124.01 - 1 sample)
  a. Inspection Scope
      During April 14 to 17, 2014, the inspectors reviewed NextEra performance in assessing
      the radiological hazards and exposure control for OR16. The inspectors used the
      requirements in 10 CFR Part 20 and guidance in Regulatory Guide (RG) 8.38 Control
      of Access to High and Very High Radiation Areas for Nuclear Plants, TSs, and NextEra
      procedures required by TSs as criteria for determining compliance.
      Radiological Hazard Assessment
      The inspectors reviewed the last two radiological surveys from the primary channel
      heads in the four steam generators and from the reactor cavity. The inspectors
      evaluated whether the thoroughness and frequency of the surveys were appropriate
      for the given radiological hazard.
      The inspectors selected the following radiologically-significant work activities:
          Steam Generator Eddy Current Testing and Tube Plugging
          Reactor Cavity Work during OR16, Includes Reactor Head Lift/Set
          Replace Reactor Head O-ring
      The inspectors evaluated whether continuous air monitors (CAMs) were located in areas
      that were representative of actual work areas. The inspectors evaluated the NextEra
      program for monitoring levels of loose surface contamination in areas of the plant.
      The inspectors reviewed several radiation work permits (RWP) used to access locked
      high radiation areas (LHRA) and evaluated if the specified work control instructions and
      control barriers were consistent with TS requirements for LHRA.
      The inspectors observed the Access Control Point location where NextEra monitors
      material leaving the radiological control area and inspected the methods used for
      control, survey, and release of these materials. The inspectors observed the
      performance of personnel surveying and releasing material for unrestricted use and
      evaluated whether the work was performed in accordance with plant procedures.
      The inspectors assessed whether the radiation monitoring instrumentation used for
      equipment release and personnel contamination surveys had appropriate sensitivity
      for the contamination present.
      The inspectors evaluated the adequacy of radiological controls, required surveys,
      radiation protection job coverage, and contamination controls. The inspectors evaluated
                                                                                        Enclosure
 
                                          22
NextEras use of electronic personal dosimeters (EPDs) in high noise areas that were
also high radiation areas (HRAs).
The inspectors assessed whether radiation monitoring devices were placed on the
individuals body consistent with NextEra procedures. The inspectors assessed whether
the dosimeter was placed in the location of highest expected dose or that NextEra
properly implemented an NRC-approved method of determining effective dose
equivalent. The inspectors reviewed the application of dosimetry to effectively monitor
exposure to personnel in high-radiation work areas with significant dose rate gradients.
Instructions to Workers
The inspectors reviewed several RWPs for work within airborne radioactivity areas with
the potential for individual worker internal exposures.
For these RWPs, the inspectors evaluated airborne radioactive controls and monitoring,
including potential for significant airborne levels. The inspectors assessed applicable
containment barrier integrity and the operation of temporary high-efficiency particulate
air ventilation systems.
Radiological Hazards Control and Work Coverage
The inspectors discussed with first-line health physics supervisors the controls in place
for special areas that have the potential to become very high radiation areas (VHRAs)
during certain plant operations. The inspectors assessed whether these plant
operations require communication beforehand with the health physics group, so as to
allow corresponding timely actions to properly control and monitor the radiation hazards.
Radiation Worker Performance
The inspectors observed the performance of radiation workers with respect to stated
radiation protection (RP) work requirements. The inspectors assessed whether workers
were aware of the radiological conditions in their workplace and the RWP controls/limits
in place, and whether their behavior reflected the level of radiological hazards present.
RP Technician Proficiency
The inspectors observed the performance of the RP technicians with respect to
controlling radiation work. The inspectors evaluated whether technicians were aware of
the radiological conditions in their workplace and the RWP controls/limits, and whether
their behavior was consistent with their training and qualifications with respect to the
radiological hazards and work activities.
The inspectors reviewed two radiological problem reports since the last inspection that
attributed the cause of the event to RP technician error. The inspectors evaluated
whether there was an observable pattern traceable to a similar cause. The inspectors
assessed whether this perspective matched the corrective action approach taken by
NextEra to resolve the reported problems.

2RS2 Occupational ALARA Planning and Controls (71124.02 - 1 sample)
  a. Inspection Scope
    During April 14 to 17, 2014, the inspectors assessed performance with respect to
    maintaining occupational individual and collective radiation exposures as low as is
    reasonably achievable (ALARA) for OR16. The inspectors used the requirements in
    10 CFR Part 20, RG 8.8 - Information Relevant to Ensuring that Occupational Radiation
    Exposures at Nuclear Power Plants will be As Low As Is Reasonably Achievable, RG
    8.10 - Operating Philosophy for Maintaining Occupational Radiation Exposure As Low as
    Is Reasonably Achievable, TSs, and NextEra procedures required by TSs as criteria for
    determining compliance.
    Radiological Work Planning
    The inspectors selected the following work activities that had the highest exposure
    significance.
        Pre-Job ALARA Review 14-02 OR16 Steam Generator Eddy Current Testing and
        Tube Plugging
        Pre-Job ALARA Review 14-03 OR16 In Service Inspection
        Pre-Job ALARA Review 14-07 OR16 Fuel Handling Project
        Pre-Job ALARA Review 14-09 OR16 RCP Seal Replacement
        Pre-Job ALARA Review 14-10 OR16 Scaffolding
        Pre-Job ALARA Review 14-13 Replace Reactor Ventillation Ducting Under Vessel
        with New Design
    The inspectors reviewed the ALARA work activity evaluations, exposure estimates,
    and exposure reduction requirements. The inspectors determined whether NextEra
    reasonably grouped the radiological work into work activities, based on historical
    precedence and industry standards. The inspectors compared the results achieved
    (actual dose) with the intended dose for these work activities. The inspectors compared
    the person-hour estimates provided by maintenance planning and other groups to the
    RP group actual person-hours for the work activity, and evaluated the accuracy of these
    time estimates. The inspectors assessed the reasons for any inconsistencies between
    intended and actual work activity doses.
    Verification of Dose Estimates and Exposure Tracking Systems
    The inspectors reviewed the assumptions and basis for the collective dose estimates for
    routine operations and the refueling outage. The inspectors reviewed applicable
    procedures to determine the methodology for estimating exposures from specific work
    activities and for department and station collective dose goals.
    The inspectors evaluated whether the licensee had established measures to track, trend,
    and to reduce occupational doses for ongoing work activities. The inspectors assessed
                                                                                      Enclosure
 
                                              24
    whether dose threshold criteria were established to prompt additional ALARA planning
    and controls.
    The inspectors evaluated the licensees method of adjusting exposure estimates, or
    re-planning work, when unexpected changes in scope or emergent work were
    encountered. The inspectors assessed whether adjustments to exposure estimates
    were based on sound RP and ALARA principles or if they were just adjusted to account
    for failures to plan/control the work.
    Radiation Worker Performance
    The inspectors observed radiation worker and RP technician performance during work
    activities being performed in radiation areas, airborne radioactivity areas, and LHRAs.
    The inspectors evaluated whether workers demonstrated the ALARA philosophy in
    practice and whether there were any procedure or RWP compliance issues.
  b. Findings
    No findings were identified.
2RS3 In-Plant Airborne Radioactivity Control and Mitigation (71124.03)
  a. Inspection Scope
    During April 14 to 17, 2014, the inspectors verified whether in-plant airborne
    concentrations were being controlled consistent with ALARA principles and the use
    of respiratory protection devices on-site did not pose an undue risk to the wearer.
    The inspectors used the requirements in 10 CFR Part 20, the guidance in RG 8.15
    Acceptable Programs for Respiratory Protection, RG 8.25 Air Sampling in the
    Workplace, NUREG-0041 Manual of Respiratory Protection Against Airborne
    Radioactive Material, TSs, and NextEra procedures required by TSs as criteria for
    determining compliance.
    Inspection Planning
    The inspectors reviewed the Updated Final Safety Analysis Report to identify areas of
    the plant designed as potential airborne radiation areas and any associated ventilation
    systems or airborne monitoring instrumentation. This review included instruments used
    to identify changing airborne radiological conditions. The inspectors reviewed the
    respiratory protection program and a description of the types of respiratory protection
    devices used. The inspectors reviewed the procedures for maintenance, inspection, and
    use of respiratory protection equipment including self-contained breathing apparatus, as
    well as, procedures for air quality maintenance. The inspectors reviewed reported
    performance indicators to identify any related to unintended dose resulting from intakes
    of radioactive material.
    Engineering Controls
    The inspectors reviewed the licensees use of permanent and temporary ventilation to
    determine whether the licensee uses ventilation systems as part of its engineering
    controls to control airborne radioactivity. The inspectors reviewed procedural guidance
                                                                                      Enclosure
 
                                              25
    for use of installed plant systems to reduce dose and assessed whether the systems are
    used during high-risk activities.
    The inspectors selected two temporary ventilation system used to support work in
    contaminated areas. The inspectors assessed whether the use of these systems was
    consistent with NextEra procedural guidance and ALARA. The inspectors assessed
    whether the licensee had established threshold criteria for evaluating levels of airborne
    beta-emitting and alpha-emitting radionuclides.
    Use of Respiratory Protection Devices
    The inspectors selected two work activities where respiratory protection devices were
    used to limit the intake of radioactive materials, and assessed whether the licensee
    performed an engineering evaluation concluding that the use of respirators is not
    required based on ALARA. The inspectors also evaluated whether the licensee had
    established means (such as routine bioassay) to determine if the level of protection
    provided by the respiratory protection devices during use was at least as good as that
    assumed in the licensees work controls and dose assessment.
    The inspectors assessed whether respiratory protection devices used to limit the intake
    of radioactive materials was certified by the National Institute for Occupational Safety
    and Health/Mine Safety and Health Administration (NIOSH/MSHA) or have been
    approved by the NRC. The inspectors evaluated whether the devices were used
    consistent with their NIOSH/MSHA certification or NRC approval.
    Problem Identification and Resolution
    The inspectors evaluated whether problems associated with the control and mitigation
    of in-plant airborne radioactivity were being identified by the licensee at an appropriate
    threshold and were properly addressed for resolution in the licensee corrective action
    program. The inspectors assessed whether the corrective actions were appropriate for
    a selected sample of problems involving airborne radioactivity and were appropriately
    documented by the licensee.
  b. Findings
    No findings were identified.
2RS4 Occupational Dose Assessment (71124.04)
  a. Inspection Scope
    During April 14 to 17, 2014, the inspectors verified that occupational dose is
    appropriately monitored, assessed and reported by NextEra. The inspectors used the
    requirements in 10 CFR Part 20, the guidance in RG 8.13 - Instructions Concerning
    Prenatal Radiation Exposures, RG 8.36 - Radiation Dose to Embryo Fetus, RG 8.40 -
    Methods for Measuring Effective Dose Equivalent from External Exposure, TSs, and the
    licensees procedures required by TSs as criteria for determining compliance.

                                        26
Inspection Planning
The inspectors reviewed the results of NextEra RP program audits related to internal
and external dosimetry. The inspectors reviewed the most recent National Voluntary
Laboratory Accreditation Program (NVLAP) report on the principal dosimetry used to
establish dose of legal record.
A review was conducted of NextEra procedures associated with dosimetry operations,
including issuance/use of external dosimetry, and assessments of external and internal
dose for radiological incidents. The inspectors evaluated whether NextEra had
established procedural requirements for determining when external dosimetry and
internal dose assessments are required.
External Dosimetry
The inspectors evaluated whether the NextEra dosimetry vendor is NVLAP accredited
and if the approved irradiation test categories for each type of personnel dosimeter used
are consistent with the types and energies of the radiation present.
The inspectors evaluated the onsite storage of dosimeters before issuance, during use,
and before processing/reading. The inspectors also reviewed the guidance provided to
radiation workers with respect to use of dosimeters.
The inspectors assessed the use of EPDs to determine if NextEra uses a correction
factor to address the response of the EPD as compared to the dosimeter of legal record
for situations when the EPD is used to assign dose.
The inspectors reviewed three dosimetry occurrence reports or corrective action
program documents for adverse trends related to EPDs. The inspectors assessed
whether NextEra had identified any adverse trends and implemented appropriate
corrective actions.
Internal Dosimetry
Routine Bioassay (In Vivo)
The inspectors reviewed procedures used to assess the dose from internally deposited
radionuclides using whole body count (WBC) equipment. The inspectors evaluated
whether the procedures addressed methods for differentiating between internal and
external contamination, the release of contaminated individuals, determining the route of
intake and the assignment of dose.
The inspectors reviewed the whole body count process to determine if the frequency of
measurements was consistent with the biological half-life of the radionuclides available
for intake.
The inspectors reviewed NextEra evaluation for use of its portal radiation monitors as a
passive monitoring system. The inspectors assessed if instrument minimum detectable
activities were adequate to determine the potential for internally deposited radionuclides
sufficient to prompt an investigation.

                                          27
Special Bioassay (In Vitro)
There were no internal dose assessments obtained using In Vitro results for the
inspectors to review, i.e., no urinalysis or fecal sample results.
The inspectors reviewed the vendor laboratory quality assurance program and assessed
whether the laboratory participated in an industry recognized cross-check program
including whether out-of-tolerance results were reviewed, evaluated and resolved
appropriately.
Internal Dose Assessment - Airborne Monitoring
NextEras had not performed any internal dose assessments using airborne/derived air
concentration monitoring during the period reviewed.
Special Dosimetric Situations
Declared Pregnant Workers
The inspectors assessed whether NextEra informs workers of the risks of radiation
exposure to the embryo/fetus, the regulatory aspects of declaring a pregnancy, and the
specific process to be used for voluntarily declaring a pregnancy.
The inspectors reviewed the records of one individual who had declared pregnancy
during the current assessment period and evaluated whether the NextEras radiological
monitoring program (internal and external) for declared pregnant workers is technically
adequate to assess the dose to the embryo/fetus. The inspectors reviewed exposure
results and monitoring controls that were implemented for declared pregnant workers
during the inspection period.
Dosimeter Placement and Assessment of Effective Dose Equivalent for External
Exposures
The inspectors reviewed the NextEra methodology for monitoring external dose in non-
uniform radiation fields where large dose gradients exist. The inspectors evaluated the
NextEra criteria for determining when alternate monitoring, such as use of multi-badging,
is to be implemented. The inspectors reviewed selected dose assessments performed
using multi-badging to evaluate whether the assessment was performed consistent with
procedures and dosimetric standards.
Shallow Dose Equivalent
The inspectors reviewed one dose assessments for shallow dose equivalent for
adequacy. The inspectors evaluated the NextEra method for calculating shallow dose
equivalent from distributed skin contamination.
Neutron Dose Assessment
The inspectors evaluated the NextEras neutron dosimetry program, including dosimeter
types and radiation survey instrumentation.
                                                                                Enclosure
 
                                                28
    The inspectors reviewed neutron exposure occurrences and assessed whether
    (a) dosimetry and instrumentation was appropriate for the expected neutron spectra,
    (b) there was sufficient sensitivity for low dose and/or dose rate measurement, and
    (c) neutron dosimetry and neutron detection instruments were properly calibrated. The
    inspectors also assessed whether interference by gamma radiation had been accounted
    for in the calibration.
    Assigning Dose of Record
    For the special dosimetric situations reviewed in this section, the inspectors assessed
    how NextEra assigns dose of record for total effective dose equivalent, shallow dose
    equivalent, and lens dose equivalent. This included an assessment of external and
    internal monitoring results, supplementary information on individual exposures, and
    radiation surveys when dose assignment was based on these techniques.
    Problem Identification and Resolution
    The inspectors assessed whether problems associated with occupational dose
    assessment were being identified by NextEra at an appropriate threshold and are
    properly addressed for resolution in the licensee corrective action program. The
    inspectors assessed the appropriateness of the corrective actions for a selected sample
    of problems documented by the licensee involving occupational dose assessment.
  b. Findings
    No findings were identified.

    Part 190 Environmental Radiation Protection Standards for Nuclear Power Operations,
    NUREG 0737 Clarification of Three Mile Island Corrective Action Requirements,
    TSs/Offsite Dose Calculation Manual (ODCM), applicable industry standards, and
    NextEras procedures required by TSs as criteria for determining compliance.
    Inspection Planning
    The inspector reviewed the Seabrook Station UFSAR to identify radiation instruments
    associated with monitoring area radiation, airborne radioactivity, process streams,
    effluents, materials/articles, and workers. Additionally, the inspectors reviewed the
    associated TS requirements for post-accident monitoring instrumentation. The
    inspectors reviewed a listing of in-service survey instrumentation including: air

samplers, small article monitors, radiation monitoring instruments, personnel
contamination monitors, portal monitors, and whole-body counters. The inspectors
assessed whether an adequate number and type of instruments were available to
support operations. The inspectors reviewed NextEra and third-party evaluation reports
of the radiation monitoring program since the last inspection. The inspectors reviewed
procedures that govern instrument source checks and calibrations, including instruments
used for monitoring transient high radiological conditions and instruments used for
underwater radiation surveys.
Walkdowns and Observations
The inspectors walked down four effluent radiation monitoring systems, including
RM6454, Storm Drain Liquid Effluent Monitor; RM6509, Liquid Waste Test Tank
Discharge Effluent Monitor; RM6528-1, Plant Vent Wide Range Gas Monitor Effluent
Monitor; and RM6526-1, Containment Air Particulate Monitor. The inspectors assessed
whether the effluent/process monitor configurations align with what is described in the
UFSAR and the ODCM.
The inspectors selected five portable survey instruments in use or available for issuance
and assessed calibration and source check stickers for currency, as well as, instrument
material condition and operability.
The inspectors observed NextEra staff performance in conducting source checks for the
following types of portable survey instruments: MGPI Telepole, Eberline AMP-100 Area
Radiation Monitor, Ludlum 44-9 GM Frisker, Eberline RM-14 Pancake Frisker and
Eberline RO-2A Ion Chamber. The inspectors assessed whether high-range
instruments are source checked on all appropriate scales.
The inspectors walked down five area radiation monitors (ARMs) and four CAMs to
determine their adequacy and operability. The inspectors compared the ARM response
(via local readout or remote control room indications) with actual area radiological
conditions for consistency.
The inspectors selected the Argos 4AB personnel alpha/beta contamination monitor, the
GEM-5 gamma portal monitors, the CHRONOS-4 large article monitor, and the SAM-12
small article monitor located at the health physics (HP) Control Point, and evaluated
whether the periodic source checks were performed in accordance with the
manufacturers recommendations and NextEra procedures.

calibration sources were used, the sources were verified by comparison with the primary
calibration source; and (d) NextEra channel calibrations encompassed the instruments
alarm set-point range.
Laboratory Instrumentation
The inspectors assessed laboratory analytical instruments used for radiological analyses
to determine whether daily performance checks and calibration data indicate that the
frequency of the calibrations is adequate and there were no indications of degraded
performance. The inspectors assessed whether appropriate corrective actions were
implemented in response to indications of degraded performance.
Whole Body Counter (WBC)
The inspectors reviewed calibration records for the WBC and the methods and sources
used to perform functional checks on the WBC before daily use and assessed whether
calibration and check sources were appropriate and align with the plants radionuclide
mix and that appropriate calibration phantoms were used.
Portal Monitors, Personnel Contamination Monitors, and SAMs
The inspectors selected one of each type of these instruments and verified that the
alarm set-point values are reasonable to ensure that licensed material is not released
from the site. The inspectors reviewed calibration documentation for each instrument
selected and reviewed the calibration methods to determine consistency with the
manufacturers recommendations.
Portable Survey Instruments, ARMs, Electronic Dosimetry, and Air Samplers/CAMs

survey instruments and ARMs, the inspectors reviewed detector measurement geometry
and calibration methods and reviewed the use of its instrument calibrator as applicable.
Instrument Calibrator
The inspectors reviewed the current radiation output values for the licensees portable
survey and ARM instrument calibrator units. The inspectors assessed that the licensee
had verified calibrator output over the range of the exposure rates/dose rates using an
ion chamber/electrometer. The inspectors verified that the measuring devices had been
calibrated by a facility using NIST traceable methods and were properly applied by the
licensee in performing radiation survey instrument calibrations.
Calibration and Check Sources
The inspectors reviewed the NextEras waste stream characterization per 10 CFR Part
61, Licensing Requirements for Land Disposal of Radioactive Waste, to assess
whether calibration sources used were representative of the types and energies of
radiation encountered in the plant.

      Procedure 71152, Problem Identification and Resolution, to identify trends that might
      indicate the existence of more significant safety issues. In this review, the inspectors
      included repetitive or closely-related issues that may have been documented by NextEra
      outside of the CAP, such as trend reports, performance indicators, major equipment
      problem lists, system health reports, MR assessments, and maintenance or CAP
      backlogs. The inspectors also reviewed NextEras CAP database for the first and
      second quarters of 2014 to assess CRs written in various subject areas (equipment
      problems, human performance issues, etc.), as well as individual issues identified during
      the NRCs daily CR review (Section 4OA2.1). The inspectors reviewed NextEras
      quarterly trend report for the first quarter of 2014, conducted under PI-AA-207-1000,
      Station Self-Evaluation and Trending, Revision 1, to verify that NextEra personnel were
      appropriately evaluating and trending adverse conditions in accordance with applicable
      procedures.
  b. Findings and Observations
      No findings were identified.
      In general, the inspectors did not identify significant issues with the content and
      utilization of the station trending report, including any identified adverse trends, potential
      adverse trends, or management awareness areas. As a result, the inspectors evaluated
      a sample of departments that are required to provide input into the quarterly trend
      reports, which included operations, maintenance and engineering departments. This
      review included a sample of issues and events that occurred over the course of the past
      two quarters to objectively determine whether issues were appropriately considered or
      ruled as emerging or adverse trends, and in some cases, verified the appropriate
      disposition of resolved trends. The inspectors verified that these issues were addressed
      within the scope of the corrective action program, or through department review and
      documentation in the quarterly trend report for overall assessment.
      For example, the inspectors noted that consistent with the issue identified in Section
      4OA3.3, regarding the surveillance test failure, NextEra had identified that a critical
      warm-up period identified in manufacturer documents was not translated to applicable
      surveillance procedures. While this was a dated issue from several years ago, this
      aspect of design interface weaknesses was identified by electrical maintenance following
      the implementation of a design change for protective relays. However, while not
      identified specifically as a trend, the issue of appropriately ensuring design interface
      documents are appropriately revised or updated is being addressed through the
      corrective action program for the issue referenced later in this report.

                                              33
    Another example identified by the inspectors involved the use of the CAP (versus the
    trend report) to address trends in the use of the RCS Leak Rate Program. Operations
    personnel coordinated the use of the CAP and the Training Department to ensure the
    differences seen in the calculation of identified RCS leak rate were well understood by
    the control room operators, but required some potential training due to some
    weaknesses identified in this area.
4OA3 Follow-Up of Events and Notices of Enforcement Discretion (71153 - 3 samples)
.1  (Closed) Licensee Event Report (LER) 05000443/2013-001: Failure to Enter Technical
    Specification Following Discovery of SW Leak
    As documented in NRC Inspection Report, 50-443/2013-005, the inspectors
    dispositioned a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V,
    Instructions, Procedures, and Drawings, and an associated violation of technical
    specification (TS) 3.7.4, because NextEra did not follow the requirements of station
    procedure EN-AA-203-1001, Operability Determinations/ Functionality Assessments.
    Specifically, NextEra did not properly evaluate and document an adequate basis for
    operability, when relevant information was available that would have challenged the
    reasonable expectation of operability threshold for a service water (SW) through-wall
    leak that degraded incrementally from weepage on August 7, 2013, to a significantly
    larger leak on August 28, 2013. NextEra completed a temporary non-code repair of the
    flaw with the installation of a weldolet on September 1, 2013, following NRC review and
    approval of a relief request. Additionally, during refueling outage OR16, in April 2014,
    NextEra removed the temporary weldolet and installed a new piping segment to
    complete the restoration of the section of degraded piping that had developed a leak in
    August 2013. Extent of condition inspections and liner repairs were also completed for
    similar piping configurations to the degraded piping segment that were inaccessible
    during power operation. Moreover, the subject LER was submitted by NextEra when
    they had concluded, on October 30, 2013, following a review of the actions taken for the
    SW leak in question, that the plant had operated in a condition prohibited by technical
    specifications for 24 days, from August 8, 2013 to September 1, 2013. The inspector
    reviewed several extent of condition inspections, evaluations and repairs, the actual
    degraded pipe restoration activity (See Section 1R19 for the final acceptance leak test),
    and verified the adequacy of NextEras additional corrective actions for the performance
    issues that contributed to the identified TS violation. These actions included: (1)
    mentoring of individuals on documentation requirements for prompt operability
    determinations, (2) procedure revisions to ensure additional barriers are in place for
    future engineering evaluations regarding field information, assumptions and supervisory
    reviews, (3) corrective action program requirements were reinforced, and (4) a case
    study of this service water leak issue was identified to reinforce the relative issues to
    station personnel.
    As a result of this inspection, no additional findings or violations of NRC requirements
    were identified. This LER is closed.

.2    (Closed) Licensee Event Report (LER) 05000443/2014-001: Reactor Trip Due to Delay
      in Bus Transfer Resulting in Reactor Coolant Pump (RCP) Loop Low Flow
  a. Inspection Scope
      On April 1, 2014, at 00:26 while operating at approximately 15 percent power following
      turbine shutdown and removal of the main generator from service, Seabrook station
      experienced an automatic reactor trip on reactor coolant two loop loss of flow. The loss
      of flow was the result of the unexpected closure of the main generator breaker (MGB) B
      phase which caused the 345kV Bus 6 to de-energize and isolate the MGB. All buses
      transferred to the reserve auxiliary transformers as designed; however, a slight delay in
      the automatic transfer for bus 1 resulted in two RCPs tripping. The RCPs tripping
      resulted in an automatic reactor trip due to reactor coolant loop low flow. The
      emergency feedwater system actuated on low steam generator level, and all plant
      equipment functioned as expected. NextEra personnel completed a root cause
      evaluation to determine the cause of the reactor trip. Corrective actions include: revising
      procedures to add controls regarding the potential risk, ensure the use of guarded
      equipment controls, and minimizing the time spent with the main generator breaker in
      local.
      The inspectors reviewed LER 2014-001-00 and associated corrective actions and
      identified a performance deficiency that was characterized as more than minor and is
      documented below. This LER is closed.
  b. Findings
      Introduction. The inspectors identified a Green self-revealing finding, because NextEra
      did not ensure that adequate procedural guidance existed in ON1046.12, Operation of
      the Main Generator Breaker to limit the likelihood of events that upset plant stability.
      Specifically, Seabrook station experienced an automatic reactor trip from approximately
      15 percent reactor power on April 1, 2014 when two of four reactor coolant pumps
      (RCPs) tripped on low bus voltage. The cause of the reactor trip was directly attributable
      to the main generator breaker inadvertently closing and actuating the main generator
      multi-function protective relay.
      Description. At midnight on April 1, 2014, with reactor power at approximately
      15 percent, the station turbine generator was shutdown and the main generator breaker
      was opened in preparation for the start of a scheduled refueling outage. The Main
      Generator Breaker Selector Switch was subsequently aligned to local in preparation for
      scheduled main turbine overspeed testing. At 12:26 a.m., the main generator breaker
      B phase unexpectedly closed, actuating the main generator multi-function protective
      relay. As a result of the protective relay actuation, 13.8kV buses 1, 2, 3, 4, 5, and 6
      automatically transferred from the UATs to the Reserve Auxiliary Transformers (RATs).
      However, buses 1 and 5 experienced a delayed transfer from the UATs to the RATs
      based on residual bus voltage, and the two RCPs powered from buses 1 and 5 tripped
      on low bus voltage as designed. The delayed transfer of buses 1 and 5 was due to a
      combination of the delay introduced by the B pole remaining closed and initiating an out
      of synchronization condition, and the more restrictive dead band reset of the newer style
      synchronization check relays that were installed on buses 1 and 5. The subsequent loss
      of reactor coolant flow caused an automatic reactor protection system (RPS) actuation
      and reactor trip on loop low flow.
                                                                                          Enclosure
 
                                          35
NextEra determined that the cause of the B main generator breaker pole unexpected
closure was from the combination of an air leak from a stuck open pressure reducer
valve in the main generator B pole control cabinet, and inadvertent contact with the B
pole local closure push button inside the B pole control cabinet during an investigation
of the air leak by an operator. NextEra determined that the root cause for the event was
inadequate procedural guidance contained in ON1046.12, Operation of the Main
Generator Breaker to communicate the impacts of positioning the Main Generator
Selector Switch to local, take mitigating actions, and minimize time spent at increased
risk configurations. Specifically, ON1046.12 contained no cautions, notes or
prerequisites to ensure that licensee personnel were aware of the potential risk
associated with the Main Generator Selector Switch being placed in local. Specifically,
with the switch in local, the main generator breaker pole disagreement protective
features that would have auto-opened the pole upon inadvertent closure were disabled.
As a result of the lack of procedural information, licensee personnel did not implement
controls in accordance with OP-AA-102-1003, Guarded Equipment, or take measures
to minimize the time spent in the risk significant configuration. NextEra noted that
procedures used for controlling similar evolutions contain additional cautions and notes
that identify the increased risk configuration.
NextEra entered the event into their CAP (AR 01953543), and conducted a root cause
evaluation to determine the root and contributing causes, extent of condition and extent
of cause, and to identify corrective actions to prevent recurrence. NextEra initiated
actions to revise ON1046.12 to add controls to communicate the potential risk
associated with placing the main generator breaker control in local, conducted briefings
with Maintenance groups involved in the event, and evaluated the adequacy of other
Operations procedures that place equipment in a configuration where protective features
are bypassed or defeated. The inspectors reviewed the root cause evaluation and
associated documentation, and determined that NextEra adequately identified the root
and contributing causes and implemented appropriate corrective actions to prevent
recurrence.
Analysis. The inspectors determined that the inadequate procedural guidance contained
in ON1046.12, Operation of the Main Generator Breaker was a performance deficiency
that was within NextEras ability to foresee and correct. The performance deficiency was
more than minor because it was associated with the procedure quality attribute of the
Initiating Events cornerstone, and it adversely affected the cornerstone objective to limit
the likelihood of events that upset plant stability and challenge critical safety functions
during shutdown as well as power operations. The finding was evaluated under IMC
0609, Attachment 4, Phase 1 - Initial Characterization of Findings. The inspectors
determined that the finding is of very low safety significance (Green) because it did not
result both in a reactor trip and the loss of mitigating equipment relied upon to transition
the plant from the onset of the trip to a stable shutdown condition. The finding has a
cross-cutting aspect in the area of Human Performance - Work Management, because
NextEra did not ensure that a process of planning, controlling, and executing work
activities such that nuclear safety is the overriding priority was implemented (H.5).
Specifically, ON1046.12, Operation of the Main Generator Breaker did not contain
adequate procedural guidance regarding the impacts of positioning the Main Generator
Selector Switch to local, take mitigating actions, and minimize time spent at increased
risk configurations [H.5].

    Enforcement. Enforcement action does not apply because the performance deficiency
    did not involve a violation of a regulatory requirement. (FIN 05000443/2014003-02,

.3  (Closed) Licensee Event Report (LER) 05000443/2014-002: Reactor Coolant Pump
    Undervoltage Time Delay Relay Exceeds Acceptance
    On April 6, 2014, during a refueling outage, routine RPS surveillance testing identified
    that three of four reactor coolant pump (RCP) undervoltage (UV) reactor trip channels
    exceeded the TS channel response time acceptance criteria of 1.5 seconds for the RCP
    UV reactor trip function. NextEra determined that since this condition involved multiple
    similar components, there is evidence indicating that this condition may have arisen over
    time and three channels of RCP UV were concurrently inoperable. This resulted in the
    plant operating in a condition prohibited by TSs for approximately seventeen months.
    NextEra personnel initiated a root cause evaluation to determine the cause of the
    violation and determine appropriate corrective actions, replaced one relay, and adjusted
    the remaining relays to acceptable response times.
    The inspectors reviewed LER 2014-002-00 and associated corrective actions and
    dispositioned the issue as a licensee identified violation of regulatory requirements. The
    enforcement aspects of this issue are discussed in Section 4OA7. This LER is closed.
4OA6 Meetings, Including Exit
    On July 10, 2014, the inspectors presented the inspection results to Mr. Dean Curtland,
    Site vice President, and other members of the Seabrook Station staff. The inspectors
    verified that no proprietary information was retained by the inspectors or documented in
    this report.
4OA7 Licensee-Identified Violation
    The following violation of very low safety significance (Green) was identified by NextEra
    and is a violation of NRC requirements which meets the criteria of the NRC Enforcement
    Policy for being dispositioned as an NCV.
        Technical Specification (TS) Surveillance Requirement 4.3.1.2 requires verification of
        the response time of each reactor trip function every 18 months. During the 18
        month surveillance testing of the RCP UV channels conducted on April 6, 2014,
        three of the four RCP UV relays exceeded their allowable maximum response time,
        resulting in their associated UV reactor trip channels exceeding the limit of 1.5
        seconds. NextEra determined that the three channels were inoperable. TS 3.3.1,
        Reactor Trip System Instrumentation, requires four channels of RCP UV
        instrumentation to be operable in Mode 1. With three RCP UV channels inoperable
        in Mode 1, the plant is required to initiate a shutdown within one hour in accordance
        with TS 3.0.3. NextEra determined that this condition existed from the time the
        relays were last calibrated in OR15 (September 20, 2012) until the plant entered
        OR16 (April 1, 2014). Contrary to TS 3.0.3, Seabrook station operated in Mode 1
        with three of four RCP UV channels inoperable for approximately 17 months without
        taking the required TS actions. NextEra entered this issue into the CAP as AR
        01964167 and performed a detailed analysis of the impact of the increased channel
                                                                                        Enclosure
 
                                            37
      response time. NextEra, in consultation with Westinghouse, determined that the
      safety function of the RCP UV trip channel (prevention of departure from nucleate
      boiling) was maintained throughout the period of inoperability. NextEra planned to
      develop a maintenance procedure to allow for on-line re-calibration of the RCP
      UV relays. The inspectors determined that the finding was of very low safety
      significance (Green) in accordance with IMC 0609, Appendix A, Determining the
      Significance of Reactor Inspection Findings for At-Power Situations because the
      deficiency did not affect a single RPS trip signal to initiate a reactor scram and the
      function of other redundant trips or diverse methods of reactor shutdown, did not
      involve control manipulations that unintentionally added positive reactivity, and did
      not result in a mismanagement of reactivity by operators.
