SUBJECT: SEABROOK STATION, UNIT NO. 1 - NRC INTEGRATED INSPECTION REPORT 05000443/2014002

Dear Mr. Walsh:

On March 31, 2014, the U. S. Nuclear Regulatory Commission (NRC) completed an inspection at Seabrook Station, Unit No. 1. The enclosed inspection report documents the inspection results, which were discussed on April 10, 2014, with you and other members of your staff.

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

This report documents one NRC-identified finding of very low safety significance (Green). This finding was determined to involve a violation of NRC requirements. However, because of the

very low safety significance, and because it was entered into your corrective action program (CAP), the NRC is treating the finding as a non-cited violation (NCV), consistent with Section 2.3.2.a of the NRC Enforcement Policy. If you cont

est the subject or severity of any NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control

Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at Seabrook Station. In addition, if you

disagree with the cross-cutting aspect assigned to the finding in this report, you should provide

a response within 30 days of the date of this inspection report, with the basis for your

disagreement, to the Regional Administrator, Region I, and the NRC Resident Inspector at

Seabrook Station.

Additionally, as we informed you in the most recent NRC integrated inspection report, cross-

cutting aspects identified in the last six months of 2013 using the previous terminology were

being converted in accordance with the cross-reference in Inspection Manual Chapter (IMC) 0310. Section 4OA5 of the enclosed report documents the conversion of these cross-cutting

K. Walsh 2

aspects which will be evaluated for cross-cutting themes and potential substantive cross-cutting issues in accordance with IMC 0305 starting with the 2014 mid-cycle assessment review. If you disagree with the cross-cutting aspect assigned, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region I, and the NRC Resident Inspector at Seabrook Station.

In accordance with Title 10 of the Code of Federal Regulations (CFR) 2.390 of the NRCs "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available

electronically for public inspection in the NRC's Public Document Room or from the Publicly

SUMMARY

IR 05000443/2014002; 01/01/2014-03/31/2014; Seabrook Station, Unit No. 1;

Operability Determinations and Functionality Assessments.

This report covered a three-month period of inspection by resident inspectors and announced inspections performed by regional inspectors. Inspectors identified one finding of very low

safety significance (Green), which was an NCV. The significance of most findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using IMC 0609, "Significance Determination Process" (SDP), 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 NRC's

Enforcement Policy, dated June 7, 2012. The NRC's program for overseeing the safe operation

of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight

Process," Revision 4.

Cornerstone: Mitigating Systems

Green. The inspectors identified an NCV of 10 CFR Part 50, Appendix B, Criterion V, "Procedures," because NextEra did not ensure adequate separation was maintained between temporary scaffolding and safety-related equipment. Specifically, six instances

of scaffolding installed in the plant were identified with less than the minimum standoff

distance to safety-related equipment specified in NextEra procedures and no corresponding engineering evaluation to support these deviations. NextEra entered this NCV into their CAP as AR 01933827 and assessed the six deviations for any impact on the associated

safety-related systems.

This performance deficiency was considered 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, NextEra did not

evaluate scaffolding installations when insufficient separation to safety-related equipment existed after procedural requirements were revised to a more restrictive value. Additionally,

it was similar to example 4.a in IMC 0612, Appendix E, "Examples of Minor Issues," which states that the issue of failing to appropriately evaluate scaffold installation as required by procedures is more than minor if the licensee routinely failed to perform engineering

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 involve the loss or degradation of equipment or function specifically designed to mitigate a seismic event. This finding has a cross-cutting aspect in the area of Problem Identification and Resolution, Evaluation, because NextEra

personnel did not perform an adequate extent of condition review after revision of their

erection of scaffold procedure. This performance deficiency directly contributed to multiple

instances of scaffold members erected within two inches of safety-related equipment without

an engineering evaluation [P.2]. (Section 1R15)

1R06 Flood Protection Measures (71111.06 - 1 sample)

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 'B'

EDG 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.

1R11 Licensed Operator Requalification Program (71111.11 - 2 samples)

.1 Quarterly Review of Licensed Operator Requalification Testing and Training

a. Inspection Scope

The inspectors observed licensed operator simulator training on January 23, 2014,

which included simulated degraded equipment and subsequent equipment failures

and initiators, which resulted in escalating degraded plant conditions that ensured implementation of emergency operating procedures by the operating crew, as well as implementation of the emergency plan. This emergency plan implementation included

classification of specific events that warranted an Alert Event Declaration. 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 control room supervisor.

Additionally, the inspectors assessed the ability of the crew and training staff to identify

and document crew performance problems.

b. Findings

No findings were identified.

.2 Quarterly Review of Licensed Operator Performance in the Main Control Room

a. Inspection Scope

The inspectors observed general control room activities, including alarm response and control room shift turnovers, conducted on January 13, 2014, March 14, 2014 and

7

Enclosure

March 27, 2014. Additionally the inspectors observed turbine control valve testing on January 17, 2014, engineered safety features actuation system (ESFAS) relay testing

on January 27, 2014, operator response to a failed open 'B' steam generator feed

regulating bypass valve on March 14, 2014, and restoration from enclosure building

exhaust fan EAH-FN-4A testing on March 19, 2014. The inspectors observed 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, or 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 evaluat

ing 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.

b. Findings

No findings were identified.

1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13 - 5 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 station's probabilistic risk analyst to verify plant conditions

b. Findings

No findings were identified.

1R15 Operability Determinations and Functionality Assessments (71111.15 - 7 samples)

a. Inspection Scope

The inspectors reviewed operability determinations for the following degraded or non-

conforming conditions:

East and west pipe chase low temperature impact on feedwater isolation valve

operability on January 3, 2014 Operability of safety-related equipment in close proximity to temporary scaffolding on

January 16, 2014 Service water pumphouse seismic monitor non-functional following monthly testing

on January 24, 2014 Containment enclosure ventilation area seal gaps identified on January 28, 2014 'A' EDG did not trip on overspeed during return to service testing on February 14, 2014 Reactor coolant system (RCS) leakage into the RHR system on March 13, 2014 Turbine-driven EFW pump P-37B oil leak identified during testing on March 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 NextEra's 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

Introduction. The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion V, "Procedures," because NextEra did not ensure adequate separation was

maintained between temporary scaffolding and safety-related equipment. Specifically,

9

Enclosure

six instances of scaffolding installed in the plant were identified with less than the minimum standoff distance to safety-related equipment specified in NextEra procedures

and no corresponding engineering evaluation to support these deviations.

Description. 10 CFR 50, Appendix B, Criterion V, requires that activities affecting quality be prescribed by documented procedures and be accomplished in accordance with those procedures. When used in the plant, the design and installation of temporary scaffolding must be controlled to ensure that it is not installed too close to safety-related

equipment. During a seismic event, scaffolding installed too close to safety-related

equipment can come into contact with that equipment, cause damage to it, and affect its

safety function. NextEra procedures control the installation of temporary scaffolding at Seabrook by specifying a minimum separation between scaffolding and safety-related equipment, and by requiring an engineering evaluation when the minimum separation

cannot be met.

NextEra mechanical maintenance procedure, MS0599.47, "Erection of Scaffolding," Revision 2, states that members of scaffolding erected adjacent to operable safety-related equipment shall not be less than two inches unless justified by an Engineering Evaluation. MS0599.47 was revised in February 2013, and the requirement for scaffold

separation from operable safety-related equipment was changed from "...should not be

less than 2 inches and in no case less than 1/2 inch without an engineering evaluation" to

"...shall not be less than 2 inches unless justified by engineering evaluation."

While performing a plant walkdown on January 15, 2014, the inspectors identified

temporary scaffold members installed less than two inches from the 'A' Containment Building Spray (CBS) pump discharge and suction lines. The 'A' CBS pump and its

associated piping are classified as safety-related equipment and were operable at the time. The identified scaffold did not include an engineering evaluation that provided acceptance of separation of less than two inches. Subsequent plant walkdowns by

NextEra personnel identified five additional instances of scaffolding installed less than

two inches from operable safety-related equipment without an associated engineering

evaluation. NextEra personnel determined that an inadequate extent of condition review

following the February 2013 revision of MS0599.47, resulted in scaffolding being staged in the plant at less than the new, more restrictive scaffold separation requirement of two inches. Having identified multiple instances where NextEra personnel had not complied

with the separation requirement of the scaffolding procedure, the inspectors concluded

that NextEra had not been adequately controlling the design and installation of

temporary scaffolding.

NextEra entered the additional instances of inadequate separation identified during their

independent walkdowns into the CAP. All discrepancies were corrected and assessed

for any potential impact to the operability or functionality of affected systems. The

inspectors reviewed the CRs and determined that the safety function of each system

potentially impacted by temporary scaffolding, including those identified by the inspectors and NextEra, would not have been affected during a seismic event.

Analysis. The inspectors determined that not providing adequate separation between temporary scaffolding and safety-related equipment without an engineering basis was

a performance deficiency within NextEra's ability to foresee and correct. Specifically, several scaffold members were observed within two inches of safety-related equipment without an engineering evaluation as specified by current procedural requirements.

10

Enclosure

This performance deficiency was considered more than minor because it affected the protection against external factors attribute of the Mitigating System cornerstone and its

objective to ensure the availability, reliability, and capability of systems that respond to

initiating events to prevent undesirable consequences. Specifically, NextEra did not

evaluate scaffolding installation when insufficient separation to safety-related equipment existed after procedural requirements were revised to a more restrictive value. Additionally, it was similar to example 4.a in IMC 0612, Appendix E, "Examples of Minor Issues," which states that the issue of failing to appropriately evaluate scaffold

installation as required by procedures is more than minor if the licensee routinely failed

to perform engineering 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) since it did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic event.

This finding is related to the cross-cutting area of Problem Identification and Resolution-

Evaluation, because NextEra did not thoroughly evaluate issues to ensure that

resolutions address causes and extent of conditions commensurate with their safety significance (P.2). Specifically, NextEra personnel did not perform an adequate extent of condition review after revision of their erection of scaffolding procedure. This

performance deficiency directly contributed to multiple instances of scaffolding members

erected within two inches of safety-related equipment without an engineering evaluation.

Enforcement. 10 CFR 50, Appendix B, Criterion V, requires, in part, that activities affecting quality shall be prescribed by documented procedures and shall be

accomplished in accordance with those procedures. NextEra mechanical maintenance

procedure, MS0599.47, "Erection of Scaffolding," Revision 2, states that members of

scaffolding erected adjacent to operable safety-related equipment shall not be less than

two inches from the equipment unless justifi

ed by an Engineering Evaluation. Contrary to the above, on January 15, 2014, the inspectors identified that certain activities affecting quality at Seabrook were not accomplished in accordance with documented

procedures. Specifically, following a revision of the minimum scaffolding separation

requirement in February 2013, multiple instances of scaffolding outside of the new

requirements were left uncorrected and engineering evaluations were not completed.

Installation of temporary scaffolding in the vicinity of safety-related equipment has the potential to adversely affect that equipment's performance during a seismic event because it was installed with insufficient standoff distance. After the issue was identified

by the inspectors, NextEra performed independent walkdowns of all scaffolding,

identifying five additional instances of inadequate separation distance. All identified

discrepancies were corrected or evaluated as adequate. Because this violation is of very low safety significance (Green) and NextEra entered this into their CAP (AR 01933827), this violation is being treated as an NCV consistent with the Enforcement

Policy. (NCV 05000443/2014002-01, Scaffolding Installed with Insufficient Separation to Safety Related Equipment)

1R18 Plant Modifications (71111.18 - 1 sample)

Permanent Modifications

a. Inspection Scope

The inspectors evaluated a modification that replaced the SW flow element to the 'A' EDG jacket water cooler implemented under engineering change EC280824, and

11

Enclosure

completed on February 13, 2014. The inspectors verified that the design and licensing bases, as well as the performance capability of the affected SW train and associated

components were not degraded by the modi

fication. The inspectors reviewed associated modification documents, which included topic notes, implementation work

order instructions, equivalent change revisions, applicable interface documents (for

example, drawings), and applicable post-modification testing.

b. Findings

No findings were identified.

1R19 Post-Maintenance Testing (71111.19 - 6 samples)

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.

1R22 Surveillance Testing (71111.22 - 7 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

the test results supported that equipment was capable of performing the required safety

functions. The inspectors reviewed the following surveillance tests:

Cornerstone: Emergency Preparedness

1EP4 Emergency Action Level and Emergency Plan Changes (71114.04 - 1

sample) Emergency Preparedness Drill Observation

a. Inspection Scope

NextEra implemented various changes to the Seabrook Emergency Action Levels

(EALs), Emergency Plan, and Implementing Procedures. NextEra had determined that, in accordance with 10 CFR 50.54(q)(3), any change made to the EALs, Emergency Plan, and its lower-tier implementing procedures, had not resulted in any reduction in

effectiveness of the Plan, and that the revised Plan continued to meet the standards in

50.47(b) and the requirements of 10 CFR 50, Appendix E.

The inspectors performed an in-office review of all EAL and Emergency Plan changes submitted by NextEra as required by 10 CFR 50.54(q)(5), including the changes to lower-tier emergency plan implementing procedures, to evaluate for any potential

reductions in effectiveness of the Emergency Plan. This review by the inspectors was

not documented in an NRC Safety Evaluation Report and does not constitute formal

NRC approval of the changes. Therefore, these changes remain subject to future NRC inspection in their entirety. The requirements in 10 CFR 50.54(q) were used as

reference criteria.

b. Findings

No findings were identified.

1EP6 Drill Evaluation (71114.06 - 2

samples) .1 Emergency Preparedness Drill Observation

a. Inspection Scope

activities. The inspectors observed emergency response operations in the simulator and technical support center to determine whether the event classification and notification

activities were performed in accordance with procedures. The inspectors also attended

the individual facility drill critique to compare inspector observations with those identified

by NextEra staff, to evaluate NextEra's critique and to verify whether NextEra staff was

properly identifying weaknesses and entering them into the CAP.

b. Findings

.2 Emergency Preparedness Training Observations

a. Inspection Scope

The inspectors observed a simulator training evolution for Unit 1 licensed operators on January 23, 2014, which involved simulated emergency plan implementation by an operations crew. NextEra planned for this evolution to be evaluated and included in

performance indicator data regarding drill and exercise performance. The inspectors

observed event classification and notification activities performed by the crew. The inspectors also attended the post-evolution critique for the scenario. The focus of the

inspectors' activities was to note any weaknesses and deficiencies in the crew's performance and ensure that NextEra evaluators noted the same issues and entered them into the CAP.

b. Findings

No findings were identified.

2. RADIATION SAFETY

Cornerstone: Public Radiation Safety

2RS1 Radiological Hazard Assessment and Exposure Controls (71124.01)

a. Inspection Scope

From March 4 to March 8, 2014, the inspectors reviewed NextEra's performance in assessing the radiological hazards and exposure control in the workplace. 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 the NextEra procedures required by TSs, as criteria for determining

compliance.

Inspection Planning

The inspectors reviewed 2013 NextEra performance indicators for the occupational

exposure cornerstone for Seabrook Nuclear Station. The inspectors reviewed the

results of radiation protection program audits. The inspectors reviewed any reports of operational occurrences related to occupational radiation safety since the last inspection.

14

Enclosure

Radiological Hazard Assessment

The inspectors determined if there have been changes to plant operations since the last

inspection that may result in significant new radiological hazards. The inspectors

evaluated whether NextEra assessed the potential impact of these changes and has

implemented periodic monitoring, as appropriate, to detect and quantify the radiological hazard.

The inspectors reviewed the last two radiological surveys from the Fuel Transfer Canal

and Letdown Line in the Demineralizer Alley. The inspectors evaluated whether the

thoroughness and frequency of the surveys were appropriate for the given new radiological hazard.

The inspectors conducted walk-downs and independent radiation measurements in the

facility, including radioactive waste processing, storage, and handling areas to evaluate

material and radiological conditions.

The inspectors reviewed one risk-significant wo

rk activity that involved exposure to radiation. This activity was the initial entry, survey and decontamination of the fuel

transfer canal following the second dry spent fuel storage cask loading campaign. For

this work activity, the inspectors assessed whether the pre-work surveys performed were

appropriate to identify and quantify the radiological hazard and to establish adequate protective measures. The inspectors ev

aluated the radiological survey program to determine if radiological hazards were properly identified (e.g., discrete radioactive hot

particles, transuranics and hard to detect nuclides in air samples, transient dose rates

and large gradients in radiation dose rates).

The inspectors observed work in potential airborne radioactivity areas, and evaluated whether the air samples from the fuel transfer canal

air sample locations were representative of the breathing air zone and were properly evaluated.

Instructions to Workers

The inspectors selected three

containers of radioactive materials and assessed whether the containers were labeled and controlled in accordance with 10 CFR Part 20

requirements.

The inspectors reviewed the following radiation work permits (RWP) used to access high radiation areas (HRA) and evaluated if the specified work control instructions and control barriers were consistent with TS requirements for HRA.

RWP 14-0015 High Integrity Container/Liner Shipping Preparation to include Capping, Weighing and Transfer to Waste Processing Building, January 1, 2014 RWP 14-0022 Inspect CS Valves inside Letdown Valve Room at Power, January 15, 2014 RWP 14-0027 Primary Auxiliary Building Demineralizer Alley Work/Entry, December 31, 2013 RWP 14-0058 Fuel Storage Building Transfer Canal Radiation Protection Survey, Decontamination and Maintenance Support Activities, March 2, 2014

15

Enclosure

For these RWPs, the inspectors assessed whether allowable stay-times or permissible dose for radiologically significant work under each RWP were clearly identified. The

inspectors evaluated whether electronic personnel dosimeter (EPD) alarm set-points were in conformance with survey indications and plant procedural requirements.

The inspectors reviewed two

occurrences where a worker's EPD malfunctioned or alarmed. The inspectors evaluated whether workers responded appropriately. The inspectors assessed whether the issue was included in the corrective action program and whether compensatory dose evaluations were conducted as appropriate.

For work activities that could suddenly increase radiological conditions, the inspectors assessed the NextEra means to inform workers of these changes.

Contamination and Radioactive Material Control

The inspectors reviewed NextEra's criteria for the survey and release of potentially contaminated material. The inspectors evaluated whether there was sufficient procedural guidance on alarm response.

The inspectors reviewed NextEra's procedures and records to verify that the radiation

detection instrumentation was used at an appropriate sensitivity level. The inspectors

selected six sealed sources from the NextEra inventory records and reviewed whether the sources were accounted for and were tested for loose surface contamination.

The inspectors evaluated whether any recent transactions involving nationally tracked sources were reported in accordance with 10 CFR Part 20 requirements.

Radiological Hazards Control and Work Coverage

The inspectors evaluated ambient radiological conditions and performed independent

radiation measurements during walk-downs of the facility. The inspectors assessed

whether the conditions were consistent with applicable posted surveys, RWPs, and

associated worker briefings.

The inspectors examined NextEra physical and programmatic controls for highly

activated or contaminated materials stored within spent fuel and other storage pools.

The inspectors assessed whether appropriate controls were in place to preclude

inadvertent removal of these materials from the pool.

The inspectors examined the posting and physical controls for selected HRAs, locked

high radiation area (LHRA) and very high radiation areas (VHRA) to verify conformance

with the occupational performance indicator.

Risk-Significant HRA and VHRA Controls

The inspectors discussed with the

Radiation Protection Manager

(RPM) the controls and procedures for high-risk HRAs and VHRAs. The inspectors assessed whether any

changes to NextEra relevant procedures reduce the effectiveness of worker protection.

16

Enclosure

The inspectors evaluated NextEra controls for VHRAs and areas with the potential to become a VHRA to ensure that an individual was not able to gain unauthorized access

to these areas.

Problem Identification and Resolution

The inspectors evaluated whether problems associated with radiation monitoring and exposure control were being identified by NextEra at an appropriate threshold and were

properly addressed for resolution in the licensee's corrective action program. The

inspectors assessed the appropriateness of the corrective actions for problems

documented by NextEra that involve radiation monitoring and exposure controls. The inspectors assessed NextEra processes for applying operating experience to their plant. b. Findings

No findings were identified.

2RS2 Occupational ALARA Planning and Controls (71124.02)

a. Inspection Scope

The inspectors assessed performance with respect to maintaining occupational

individual and collective radiation exposures as low as is reasonably achievable (ALARA). 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.

Inspection Planning

The inspectors reviewed information regarding Seabrook's collective dose history,

current exposure trends, and ongoing or planned activities in order to assess current performance and exposure challenges. The inspectors reviewed the plant's three year rolling average collective radiation exposure.

The inspectors compared the site-specific trends in collective exposures against the industry average values and from similar nuclear power plants. In addition, the inspectors reviewed any changes in the radioactive source term by reviewing the trend in average contact dose rate with reactor coolant piping and steam generator primary

channel head space and manways. The inspectors reviewed site-specific procedures

associated with maintaining occupational exposures ALARA, which included a review of

processes used to estimate and track exposures from specific work activities.

Radiological Work Planning

The inspectors assessed whether NextEra planning identified appropriate dose

reduction techniques; considered alternate dose reduction features; and estimated

reasonable dose goals. The inspectors evaluated whether NextEra's ALARA assessment had taken into account decreased worker efficiency from use of respiratory protective devices and/or heat stress mitigation equipment. The inspectors determined

17

Enclosure

whether NextEra work planning considered the use of remote technologies as a means to reduce dose and the use of dose reduction insights from industry operating

experience and plant-specific lessons learned. The inspectors assessed the integration

of ALARA requirements into work procedure and RWP documents.

Source Term Reduction and Control

The inspectors used licensee records to determine the historical trends and current

status of plant source term known to contribute to elevated facility collective dose. The

inspectors assessed whether the licensee had developed contingency plans for

expected changes in the source term as the

result of changes in plant fuel performance issues or changes in plant primary chemistry.

Problem Identification and Resolution

The inspectors evaluated whether problems associated with ALARA planning and controls are being identified by the licensee at an appropriate threshold and were properly addressed for resolution in the licensee's corrective action program. The

inspectors assessed NextEra's process for applying operating experience to their plant.

b. Findings

No findings were identified.

4. OTHER ACTIVITIES

4OA1 Performance Indicator Verification (71151)

Unplanned Scrams, Unplanned Power Changes, and Unplanned Scrams with

Complications (3 samples)

a. Inspection Scope

The inspectors reviewed NextEra's submittals for the following Initiating Events Cornerstone performance indicators for the period of January 1, 2013 through

December 31, 2013.

Unplanned scrams per 7000 critical hours Unplanned scrams with complications Unplanned power changes per 7000 critical hours

To determine the accuracy of the performance indicator data reported during those

periods, inspectors used definitions and guidance contained in Nuclear Energy Institute

(NEI) Document 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 6. The inspectors reviewed NextEra's operator narrative logs, event reports, and NRC integrated inspection reports to validate the accuracy of the submittals.

b. Findings

Enclosure

4OA2 Problem Identification and Resolution (71152 - 2 samples)

.1 Routine Review of Problem Identification and Resolution Activities

a. Inspection Scope

As required by Inspection Procedure 71152, "Problem Identification and Resolution," the

inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that NextEra entered issues into the CAP at an appropriate

threshold, gave adequate attention to timely corrective actions, and identified and

addressed adverse trends. In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the CAP and periodically attended

condition report screening meetings.

b. Findings

No findings were identified.

.2 Annual Sample: Increasing Frequency of Leaks in Service Water Piping in the Vicinity of Installation/Fabrication Welds

a. Inspection Scope

During the period January 27 to January 31, 2014, inspectors reviewed a root cause

evaluation (RCE AR 16379222) completed by NextEra staff for a service water pipe leak

that occurred in August 2013. This problem was described in a licensee event report submitted to the NRC dated December 23, 2013. The inspectors determined the effectiveness of actions by NextEra staff to identify, characterize, correct and prevent

reoccurrence of SW system leaks.

The inspectors assessed problem identification threshold, apparent cause analysis,

extent of condition reviews, and timeliness of corrective actions. The inspectors reviewed documents listed in the Attachment to this report and interviewed NextEra engineering personnel to assess the effectiveness of the planned, scheduled, and

completed corrective actions to resolve the identified deficiency.

The inspectors reviewed non-destructive test procedures, procedure qualifications including test personnel qualifications to determine compliance with the applicable American Society of Mechanical Engineers codes and standards. Also, the inspectors

reviewed system health reports, work orders, procurement documents, drawings and

photographs to determine if the nonconforming condition was appropriately identified,

documented, characterized and entered into NextEra's corrective action process.

The inspectors reviewed root cause evaluation AR 16379222 and interviewed members of the evaluation team. The inspectors interviewed the qualified non-destructive test

examiner to evaluate the ultrasonic test method used. Test results were reviewed with

the test examiner to assess the remaining wall thickness for continued operation without

encroaching on minimum wall requirements.

19

Enclosure

b. Findings and Observations

No findings were identified. The root cause evaluation and corrective actions were

reasonable, appropriate and timely.

NextEra's root cause evaluation addressed a history of SW degradation (corrosion/ erosion) resulting in wall thinning and pressure boundary penetration and leakage. The areas where wall thinning and leakage occurred was determined to be associated with

the loss of protective coating and/or liner failure at fabrication/installation welds which

typically results in turbulent fluid flow. This turbulent flow was particularly aggressive in

the attack of base metals and protective coatings at these weld locations and configuration changes. The inspectors assessed the root cause determination, results of the extent of condition investigation of other locations within the SW system and other

fluid (circulating water) systems with similar piping materials, operating parameters and

configurations.

The inspectors noted that examination using ultrasonic testing was performed at selected locations with known change in flow patterns and velocity changes. The results

of this testing identified areas exhibiting variable wear rates. An evaluation of these test

results was made to determine pipe structural and pressure retaining integrity.

The inspectors visually examined several portions of previous SW pipe and fittings that had been removed from the SW system in prior outages due to identified leaks. The removed samples provided confirmatory evidence of corrosive/erosive attack from turbulent flow at root locations of field welds, configuration changes and pipe to fitting

intersections. These locations revealed characteristic "pin hole" leaks at weld locations

and a general "wastage" of pipe and fitting interior diameters. These locations were evaluated for compliance with minimum wall thickness requirements. Those locations which were identified as active "leaks" at weld locations or, where areas exhibiting loss

of wall thickness and were encroaching on minimum wall requirements, were

dispositioned for repair/replacement in the CAP.

The inspectors determined that this issue received appropriate management attention as indicated by the corrective action that was taken to perform a temporary leak repair by

the installation of a weldolet encapsulating the leak location. At the next outage, (OR16) the weldolet will be removed and replaced with a more suitable "flush patch". The patch

will be coated internally with a corrosion/erosion resistant material. The inspectors

discussed the licensee plans to systematically remove and replace the SW piping with a base metal that is significantly more resistant to erosion/corrosion attack. The inspectors examined numerous lengths of pipe and fittings which were staged for

replacement in the plant during the April 2014 refueling outage and subsequent outages.

.3 Annual Sample: Review of Activities Associated with Alkali Silica Reaction Affected

Structures

a. Inspection Scope

March 12 to 13, NRC inspectors from Region I and a structural engineer from the

Division of License Renewal, NRR, wit

nessed testing conducted at the Ferguson Structural Engineering Laboratory (FSEL) at the University of Texas - Austin. The testing was conducted in support of the Seabrook Alkali-Silica Reaction (ASR)

20

Enclosure

Integrated Corrective Action Plan. Specifically, the inspectors witnessed load testing of the control beam for reinforcement anchorage (lap-splice) capacity. The testing was

performed in accordance with MPR Project 0326-0063, Procedure 5-7, "Structural

Testing of Shear and Anchorage Specimens," Revision 1.

The inspectors also reviewed the results of the December 2013, Combined Crack Indexing (CCI) measurements and the supporting engineering analysis. Proprietary data sheets and associated evaluations were made available for inspector review.

Additionally, the inspectors' review included discussions with the responsible Seabrook engineers, as well as petrography specialists consulting for the University of Texas Ferguson Structural Engineering Laboratory

Lastly, the inspectors reviewed NextEra's

revised Prompt Operability Determinations (PODs) that address additional Seabrook structures identified as being affected by ASR

via the Phase 3 ASR walkdown program.

b. Findings and Observations

The inspectors identified no findings.

Review of CCI and Crack Width Measurements

The inspectors examined the December

2013 CCI measurement results documented in Foreign Print (FP) 100847 and FP 100848, dated January 30, 2014. As documented in

these NextEra reports, there are 32 areas currently being monitored for ASR progression

using the CCI and crack width methodology. As of December 2013, 26 of the 32 areas

have been monitored on a six-month basis for approximately two years. Based upon the data collected to date, NextEra has concluded the following: 1) the data suggests a slow increasing trend in CCI and crack width over the past two years; 2) at 14 interior ASR

locations, the horizontal and vertical CCI data indicates an overall upward trend (an

average increase of 0.04 mm/m, with a measurement tolerance of 0.05 mm); 3) at nine

exterior locations, the horizontal and vertical CCI data indicates no significant change

over the two-year period; 4) the six floor/ceiling/roof locations indicate flat to upward trends early in the period, but no change later in the two-year period; and, 5) some fluctuation in the measured CCI and crack width values have been observed. The

fluctuations may be attributed to thermal effects, cyclic or constant moisture exposure,

measurement device accuracy, or the condition of the measured surfaces as impacted by cleaning/preparation and weathering effects. Independent inspector review of CCI and crack width measurement data and photographs of selected areas confirmed NextEra's conclusions. As stated in FP 100847 and FP 100848, NextEra will continue

the six-month data collection to comply with the Structures Monitoring Program and

validate these observed ASR progression trends.

Review of Operability Determinations

Based on the result of recent Phase 3 walkdowns, NextEra identified six additional areas

with CCI > 1.0 millimeter per meter (mm/m). In accordance with the Seabrook

Structures Monitoring Program (SMP), NextEra staff completed evaluations of the

affected structures to assess the potential impact of ASR on continued operability. The six additional areas identified with a CCI value greater than 1.0 mm/m were: cooling tower exterior (elevation 25', reference CTE-02); primary auxiliary building (PAB)

21

Enclosure

penetration area (elevation -26', reference MF105-01); west pipe chase (elevation 12', reference MF202-02); and three areas in elec

trical manholes (below grade elevations, reference CI-W03-Wall, CI-W05-Wall, and CI-W11-Wall). The structural evaluations

were documented as Supplement IV and V to FP 100716, "Seabrook Station: Impact of

ASR on Concrete Structures and Attachments," and utilized the same design capacity

versus calculated demand margin analysis approach as the previously completed POD's (reference Section 9.1, NRC Inspection Report 05000443/2012010). Inspector review of the six additional ASR-affected area PODs concluded that the impacted structures have

adequate strength margin available and are fully capable of performing their safety

functions.

Control Beam Testing Observations

The inspectors witnessed the performance of load testing of the first control beam (a

specimen that has not undergone ASR aging). The beam (A-7, reinforcement

anchorage control specimen) was tested in accordance with MPR Project 0326-0063, Procedure 5-7, "Structural Testing of Shear and Anchorage Specimens," Revision 1, on March 13, 2014. Beam failure occurred at a load of approximately 251,000 pounds, as

compared to the estimated failure load of 214,000 pounds. The failure load was slightly

higher than the estimated design capacity, but within the accuracy of the design

calculations. No test anomalies were identified. The results of the control beam test will

be used to compare subsequent ASR-affected specimen tests to evaluate the impact of ASR degradation on structural performance. The inspectors observed proper procedural adherence, good test coordination and proper communications and safety practices

exhibited by the testing staff, supervisory

personnel and quality assurance overseers. The inspectors verified proper testing preparations and quality control oversight as

specified by MPR Project 0326-0063, Procedure 5-6, "General Preparation of Test Facilities and Specimens," Revision 2, and MPR Procedure 0326-0062-46, "Procedure for In-process Inspections of FSEL Reinforcement Anchorage Test Setup for Seabrook

Station," Revision 0.

Initial Test Specimen ASR Expansion Results

NextEra and the UT-Austin FSEL staff have observed in the large-scale test specimens that the X- and Y-direction deep pin expansion measurements (comparable to the Seabrook vertical and horizontal wall surface CCI measurements) do not appear to

correlate with the through-wall (e.g., out-of-plane, or Z-direction) deep pin expansion

measurements after the initial phase of ASR expansion. X- and Y-direction expansion appears to plateau while the Z-direction expansion continues to trend upward (increase). All large-scale reinforcement anchorage and shear specimens have demonstrated this

expansion trend. The Z-direction expansion in the test specimens has been observed to

be 10 times greater than the X- and Y- expansions after approximately one year.

The preliminary implication of these test specimen expansion measurement trends is that the X- and Y- expansion measurement methods (CCI and crack width) currently used for monitoring the progression of ASR on Seabrook Station structure surfaces (per

the Structures Monitoring Program) may not provide alone, an adequate means to

monitor (1) ASR progression and (2) by inference (pending the completion of the testing

program), the ASR impact on the affected building's structural performance. The validation of the use of the CCI and crack width measurements for monitoring the structural impact of ASR has been an objective of the large specimen testing program.

22

Enclosure

In considering these initial test program results, NextEra staff initiated an Action Report

(No. 01952162) to address this issue. In addition to evaluating the future impact of using

CCI to monitor ASR progression on affected structures, NextEra staff conducted a

preliminary assessment of this test data for impact to their PODs completed for ASR-

affected Seabrook structures. NextEra staff concluded this initial test program data does not adversely impact the POD margins analyses, principally because the PODs are not dependent upon measured CCI values for assessing the level of ASR degradation.

Instead, those structures demonstrating the most significant ASR progression (as

assumed by CCI and crack width measurements of >1.0 mm/m and >1.0 mm,

respectively) were evaluated using conservative and bounding degradation values derived from published research and testing data developed from non-reinforced concrete specimens. At the close of the inspection period, NextEra staff had initiated

actions to re-evaluate the use of CCI and crack width for the SMP and to re-evaluate

their methods for monitoring and assessing ASR progression of test specimens in order

to correlate test data to Seabrook Station.

NextEra staff communicated with the inspectors their plans to fabricate an additional

large-scale test specimen to instrument with strain gages and allow ASR progression in

order to validate the use of strain gages for through-wall (Z-direction) expansion

monitoring. The purpose of this activity is to validate the use of one or more strain gage

designs that can subsequently be installed in Seabrook structures to accurately monitor through-wall expansion. In addition, NextEra staff described plans to increase the core sampling of control and ASR-affected large scale test specimens in order to more

accurately measure ASR impact on concrete compressive and tensile strength and

modulus of elasticity. NextEra staff further communicated plans to conduct petrographic

examination of through-wall core samples from the test specimens. This additional concrete material property testing and data collection is intended to be used to support the correlation of testing program structural performance data to Seabrook structures

(along with additional, but not yet defined, core sampling of Seabrook ASR-affected

structures).

In summary, the inspectors concluded that the PODs completed for ASR-affected Seabrook structures remain unaffected by the X-,Y- and Z-direction expansion data measured, to date, in the test specimens. Actions planned by NextEra to assess the

adequacy of the SMP structural evaluation criteria and modify the ASR testing program were viewed appropriate by the inspectors and the Seabrook ASR Issue Technical

Team, at this time. As stated above, the PODs use bounding assumptions not dependent on the degree of expansion measured. Additional inspections are planned by the NRC to evaluate NextEra's ongoing corrective actions to resolve the non-

conformance related to ASR-affected structures at the Seabrook Station.
