UNITED STATES NUCLEAR REGULATORY COMMISSION ary 1, 2016

SUBJECT:

INDIAN POINT NUCLEAR GENERATING - INTEGRATED INSPECTION REPORT 05000247/2015004 AND 05000286/2015004

Dear Mr. Coyle:

On December 31, 2015, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Indian Point Nuclear Generating (Indian Point), Units 2 and 3. The enclosed inspection report documents the inspection results, which were discussed on January 15, 2016, 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 Commissions rules and regulations and with the conditions of your license.

The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

Based on the results of this inspection, no violations of NRC requirements were identified.

However, a licensee-identified violation, which was determined to be of very low safety significance, is listed in this report. Because of the very low safety significance, and because it is entered into your corrective action program, the NRC is treating this finding as a non-cited violation, consistent with Section 2.3.2.a of the NRC Enforcement Policy. If you contest the non-cited violation 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, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Senior Resident Inspector at Indian Point.

In accordance with Title 10 of the Code of Federal Regulations (10 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 NRCs Public Document Room or from the Publicly Available Records component of the NRCs Agencywide Documents Access and Management System (ADAMS).

1R01 Adverse Weather Protection

.1 Readiness for Seasonal Extreme Weather Conditions

a. Inspection Scope

During the week of December 21, 2015, the inspectors performed a review of Entergys readiness for the onset of seasonal cold temperatures. The inspectors reviewed procedure OAP-048, Seasonal Weather Preparation (Units 2 and 3). The focused areas were the refueling water storage tank and condensate storage tank level instruments. The inspectors reviewed the Updated Final Safety Analysis Report (UFSAR), technical specifications (TSs), control room logs, and the CAP to determine what temperatures or other seasonal weather could challenge these systems and to ensure Entergy had adequately prepared for these challenges. The inspectors reviewed station procedures, including Entergys 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 cold weather conditions. Documents reviewed for each section of this inspection report are listed in the Attachment.

b. Findings

No findings were identified.

.2 External Flooding

a. Inspection Scope

During the week of November 2, 2015, the inspectors performed an inspection of the external flood protection measures for Indian Point. The inspectors reviewed TSs, procedures, design documents, and UFSAR, which depicted 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 walkdown of the Unit 2 turbine building and service water pump (SWP) area to ensure that Entergy could implement flood protection measures in accordance with their flood protection procedures. The inspectors also reviewed operating procedures for mitigating external flooding during severe weather to confirm that, overall, Entergy had established adequate measures to protect against external flooding events and, more specifically, that credited operator actions were adequate.

Unit 2 troubleshooting efforts on pressurizer pressure control switch on November 11, 2015 Unit 3 electrical plant start up conducted on December 17, 2015, following the plant trip on December 14, 2015

b. Findings

No findings were identified.

1R13 Maintenance Risk Assessments and Emergent Work Control

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 Entergy 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 Entergy performed risk assessments as required by Title 10 of the Code of Federal Regulations (10 CFR) 50.65(a)(4) and that the assessments were accurate and complete. When Entergy 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.

Unit 2 Emergent yellow risk due to loss of control power for 22 EDG on October 6, 2015 Emergent yellow fire risk due to unplanned maintenance on 23 SWP on November 30, 2015 Yellow risk with output breaker 7 open for planned maintenance on 345kV feeder Y94 on December 17, 2015 Unit 3 Yellow risk due to 31 EDG planned maintenance on October 19, 2015 Yellow risk due to 32 component cooling water pump planned maintenance from October 27 to October 30, 2015

b. Findings

No findings were identified.

1R15 Operability Determinations and Functionality Assessments

a. Inspection Scope

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

Unit 2 Phase B solenoid operated valves in the isolation valve sealing water system found closed on October 5, 2015 (CR-IP2-2015-4482)

Pressurizer pressure controller unanticipated step changes on November 4 and November 6, 2015 (CR-IP2-2015-5008 and CR-IP2-2015-5028)

Pressurizer pressure controller channel defeat switch degraded on December 10, 2015 (WO 00429927). This completed a review of the operator workaround (OWA)program Unit 3 31 main boiler feed pump controller in manual was reviewed on November 2, 2015 (WO 00426460). This completed a review of the OWA program 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 Entergys evaluations to determine whether the components or systems were operable. The inspectors confirmed, where appropriate, compliance with bounding limitations associated with the evaluations.

Where compensatory measures were required to maintain operability, such as in the case of OWAs, the inspectors determined whether the measures in place would function as intended and were properly controlled by Entergy. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations.

Based on the review of the selected OWAs listed above, the inspectors verified that Entergy identified OWAs at an appropriate threshold and addressed them in a manner that effectively managed OWA-related adverse effects on operators and structure, system, and component (SSCs).

b. Findings

No findings were identified.

1R18 Plant Modifications

Temporary Modification

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.

Unit 2 Engineering Change (EC)-60486, Bypass of transfer switch EDD6 to energize 22 EDG control circuit on October 8, 2015

b. Findings

No findings were identified.

1R19 Post-Maintenance Testing

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 test results were properly reviewed and accepted and problems were appropriately documented. The inspectors also walked down the affected job site, observed the pre-job brief and post-job critique where possible, confirmed work site cleanliness was maintained, and witnessed the test or reviewed test data to verify quality control hold point were performed and checked, and that results adequately demonstrated restoration of the affected safety functions.

1R22 Surveillance Testing

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 Entergys 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:

Unit 2 2-PT-Q 027A, 21 AFW Pump, on October 23, 2015 (this sample was part of an in-depth review of the AFW system - see Inspection Report 050000247/2015003)2-PT-M021A, EDG 21 Load Test, on November 18, 2015 2-PT02M2A, Reactor Protection System Logic Train A Actuation Logic Test and Trip Actuating Device Operational Test (Greater Than 25 Percent Reactor Power) on December 21, 2015 PT-Q026D 24 SWP on December 21, 2015 Unit 3 3-PT-Q120B, 32 Auxiliary Boiler Feedwater Pump (ABFP) Quarterly Surveillance, on October 1 and October 14, 2015 (in-service test)

b. Findings

No findings were identified.

Cornerstone: Emergency Preparedness

1EP4 Emergency Action Level and Emergency Plan Changes

a. Inspection Scope

Entergy implemented various changes to the Indian Point Emergency Action Levels (EALs), Emergency Plan, and Implementing Procedures. Entergy 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 Part 50, Appendix E.

The inspectors performed an in-office review of all EAL and Emergency Plan changes submitted by Entergy 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

Training Observations

a. Inspection Scope

The inspectors observed emergency response organization (ERO) mini-scenario training evolutions on October 19 and October 26, 2015, which required the ERO duty team for the week to perform emergency event classification and protective action recommendation development. Entergy 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, as applicable, performed by the ERO duty team. The inspectors also observed the post-evolution critique for the scenario. The focus of the inspectors activities was to note any weaknesses and deficiencies in the ERO teams performance and ensure that Entergy evaluators noted the same issues and entered them into the CAP.

b. Findings

No findings were identified.

RADIATION SAFETY

Cornerstone: Public Radiation Safety and Occupational Radiation Safety

2RS8 Radioactive Solid Waste Processing and Radioactive Material Handling, Storage, and

Transportation (71124.08 - 1 sample)

a. Inspection Scope

The inspectors verified the effectiveness of Entergys programs for processing, handling, storage, and transportation of radioactive material. The inspectors used the requirements of 49 CFR 170 to 177; 10 CFR 20, 37, 61, and 71; applicable industry standards; Regulatory Guides; and procedures required by TSs as criteria for determining compliance.

Inspection Planning The inspectors conducted an in-office review of the solid radioactive waste system description in the UFSAR, the process control program, and the recent radiological effluent release report for information on the types, amounts, and processing of radioactive waste disposed. The inspectors reviewed the scope of quality assurance audits performed for this area since the last inspection.

Radioactive Material Storage The inspectors observed radioactive waste container storage areas and verified that Entergy had established a process for monitoring the impact of long-term storage of the waste.

Radioactive Waste System Walk-Down The inspectors walked down the following items and areas:

Accessible portions of liquid and solid radioactive waste processing systems to verify current system alignment and material condition Abandoned in place radioactive waste processing equipment to review the controls in place to ensure protection of personnel Changes made to the radioactive waste processing systems since the last inspection Processes for transferring radioactive waste resin and/or sludge discharges into shipping/disposal containers Current methods and procedures for dewatering waste Waste Characterization and Classification The inspectors identified radioactive waste streams and reviewed radiochemical sample analysis results to support radioactive waste characterization. The inspectors reviewed the use of scaling factors and calculations to account for difficult-to-measure radionuclides.

Shipment Preparation The inspectors reviewed the records of shipment packaging, surveying, labeling, marking, placarding, vehicle checks, emergency instructions, disposal manifest, shipping papers provided to the driver, and Entergy verification of shipment readiness.

Shipping Records The inspectors reviewed selected non-excepted package shipment records.

Identification and Resolution of Problems The inspectors assessed whether problems associated with radioactive waste processing, handling, storage, and transportation were identified at an appropriate threshold and properly addressed in Entergys CAP.

b. Findings

No findings were identified.

OTHER ACTIVITIES

4OA2 Problem Identification and Resolution

.1 Routine Review of Problem Identification and Resolution Activities

a. Inspection Scope

As required by IP 71152, Problem Identification and Resolution, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that Entergy 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 CR screening meetings. The inspectors also confirmed, on a sampling basis, that, as applicable, for identified defects and non-conformances, Entergy performed an evaluation in accordance with 10 CFR Part 21.

b. Findings

No findings were identified.

.2 Semi-Annual Trend Review

a. Inspection Scope

The inspectors performed a semi-annual review of site issues, as required by IP 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 Entergy outside of the CAP. The inspectors also reviewed Entergys CAP database for the third and fourth quarters of 2015 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 Entergys trend report for October 2015, conducted under EN-LI-121, Trending and Performance Review Process, to verify that Entergy was appropriately evaluating and trending adverse conditions in accordance with applicable procedures.

b. Findings and Observations

No findings were identified.

The inspectors noted and discussed with Entergy staff two minor adverse trends. The first trend was associated with operator use of human performance tools in the control room during off-normal but non-emergency situations. The trend was identified after observing control room activities while excess letdown was in service on Unit 3, during plant cooldown in preparation of O-ring repairs on Unit 3, during reactor coolant system fill-and-vent following those repairs, and while the Unit 2 pressurizer pressure instrumentation was malfunctioning. During each evolution, the inspectors noted that some operators had an uncertain understanding of the expected plant response, and yet proceeded on with scheduled activities instead of stopping when unsure. At no point did the operators take an inappropriate action for the current plant configuration, and therefore, this issue was determined to be of minor significance. Entergy wrote CR-IP3-2015-4782, CR-IP3-2015-4872, and CR-IP3-2015-4897 to address these observations.

The second trend was associated with adherence to fleet procedures. At Indian Point, there are procedures written and controlled by site staff; but there are also procedures written and controlled by a group assembled from the entire Entergy nuclear fleet. The inspectors identified three instances in which the fleet procedural requirements were not met. While performing a surveillance test in the Unit 3 ABFPs, Entergy did not mark critical steps in the procedure, contrary to requirements in EN-HU-106. Entergy wrote CR-IP3-2015-3700 to address this. During the planned shutdown for the Unit 3 O-ring repairs, a reactor engineer was not present in the control room, even though EN-OP-115 requires that a reactor engineer be actively engaged in a planned shutdown.

Additionally, the inspectors identified that Entergy did not prepare contingency plans for high source terms during refueling outages, contrary to EN-RP-110-06. Entergy wrote CR-IP2-2015-5402 to address this issue. The inspectors did not identify any adverse consequence due to the procedure non-compliances and therefore determined the issue was of minor significance.

Based on the overall results of the semi-annual trend review, the inspectors determined that, generally, Entergy was appropriately identifying and entering issues into the CAP at a very low level, adequately evaluating the issues, and identifying adverse trends before they became more significant safety problems.

.3 Annual Sample: Deficient Thrust Restraint on 22 SWP

a. Inspection Scope

During a structural maintenance rule walkdown of the Unit 2 intake structure on June 24, 2014, Entergy observed a thrust restraint for 22 SWP, located in the SWP bay, which was sheared off at the upper clip angle connections. The SWP bay is essentially 100 percent humidity environment. This caused the severe corrosion identified on the carbon steel restraint and misalignment between the two pieces that were sheared off.

In addition, a 3/8-inch gap was identified between the thrust restraint and pump bearing plate. Entergy documented and evaluated the condition in CR-IP2-2014-3710.

The inspectors reviewed Entergys evaluation of the degraded thrust restraint and reviewed the corrective actions and extent of condition to resolve the deficient condition.

The inspectors reviewed EC 52592 that redesigned the support base plate on the ceiling and the repair activity performed per WO 386718. The 3/8-inch gap between restraint and SWP discharge thrust pad was restored to zero inches using shim plates. The inspectors reviewed Entergys Immediate Operability Determination, Drawing 9321-1006, Intake Structure Platform Framing Plan and Details, Calculation IP-CALC-14-00075, Redesign Anchorage of the Thrust Restraint for 22 Service Water Pump, and IP-CALC-14-00059, Evaluation of 22 Service Water Pump Due to Degraded Thrust Restraint.

Through these activities the inspectors assessed whether Entergy was appropriately identifying, characterizing, and correcting problems associated with the degraded thrust restraint on 22 SWP and whether the planned or completed corrective actions were appropriate. The inspectors compared the actions taken to the requirements of Entergys CAP and 10 CFR 50, Appendix B.

b. Findings and Observations

No findings were identified.

The review verified that Entergy staff adequately identified, characterized, and resolved problems related to the degraded thrust restraint on 22 SWP and that the corrective actions were appropriate. The inspectors reviewed the CR and corrective actions for the deficient thrust restraint to confirm that the Entergy process for identifying, evaluating, and repairing degraded components, including operability determinations, were appropriate to maintain Unit 2 service water system capability.

The thrust restraint is designed for 48,400 pounds of thrust force and IP-CALC-14-00075 calculation showed the new support connection was adequate to withstand the required loading due to this applied force. The 22 SWP shaft was evaluated in calculation IP-CALC-14-00059 and the pump was evaluated to be operable with a degraded thrust restraint prior to being repaired.

The inspectors verified that the degraded thrust restraint was appropriately identified and dispositioned with an adequate technical basis for assessing integrity of the service water system and the design function of the thrust restraint was adequately restored.

4OA3 Follow Up of Events and Notices of Enforcement Discretion

.1 Plant Events

a. Inspection Scope

For the plant events listed below, the inspectors reviewed and/or observed plant parameters, reviewed personnel performance, and evaluated performance of mitigating systems. The inspectors communicated the plant events to appropriate regional personnel, and compared the event details with criteria contained in Inspection Manual Chapter 0309, Reactive Inspection Decision Basis for Reactors, for consideration of potential reactive inspection activities. As applicable, the inspectors verified that Entergy made appropriate emergency classification assessments and properly reported the event in accordance with 10 CFR Parts 50.72 and 50.73. The inspectors reviewed Entergys follow-up actions related to the events to assure that Entergy implemented appropriate corrective actions commensurate with their safety significance.

Unit 2 reactor manual trip as the result of an electrical malfunction in the 24 motor control center and subsequent loss of power to rod control that caused dropped control rods on December 5, 2015 Unit 3 reactor trip caused by a main generator trip as the result of a 345 kV electrical system disturbance on December 14, 2015

b. Findings

No findings were identified.

.2 (Closed) Licensee Event Report (LER) 05000286/2015-005-00: Automatic Reactor Trip

Due to a Turbine-Generator Trip Caused by the Trip of 345 kV Main Generator Output Breaker 3 Due to a Failure of South Ring Bus 345 kV Breaker 5 On June 15, 2015, Unit 3 tripped from 100 percent power after the ROs opened main generator output breaker 1 at the request of Con Edison. The output of Unit 3 feeds in to the south ring bus in the Buchanan 345 kV substation between breakers 1 and 3.

With breaker 1 open, the power produced by Unit 3 flows through only breaker 3. In this configuration, the amount of power flowing through breaker 5 is also increased. When the ROs opened breaker 1, phase C on breaker 5 faulted to ground. Breaker 3 opened as designed in response to the fault. With both breaker 1 and breaker 3 open, the turbine and subsequently the reactor tripped as designed.

The inspectors reviewed Entergys post-transient evaluation and apparent cause evaluation to verify the accuracy of the LER. The inspectors also reviewed Entergys corrective actions for the trip, which included tracking Con Edisons replacement of breaker 5, and comparing the preventive maintenance performed on similar Entergy-owned breakers to the industry standards. The inspectors did not identify any new issues during the review of the LER. This LER is closed.

.3 (Closed) LER 05000286/2015-007-00: Manual Reactor Trip Due to Decreasing Steam

Generator Water Level Caused by a Mis-Wired Circuit Board in the Main Feedwater Pump Speed Control System On July 8, 2015, operators initiated a manual reactor trip in response to decreasing steam generator levels. 31 condensate pump tripped due to overcurrent caused by a windings short, lowering suction pressure available to the main boiler feedwater pumps.

Entergy determined that an incorrectly wired track and hold circuit in the 31 main boiler feedwater pump speed controller caused the pump to remain at minimum speed, the recirculation valve to open, and the discharge valve to close, resulting in insufficient feedwater for the power level. The inspectors reviewed Entergy's evaluation of the event and corrective actions documented in CR-IP3-2015-3795. The inspectors did not identify any performance deficiencies during review of the LER. This LER is closed.

4OA5 Other Activities

.1 IP 92702, Follow Up on Traditional Enforcement Actions Including Violations,

Deviations, Confirmatory Action Letters, Confirmatory Orders, and Alternate Dispute Resolution Confirmatory Orders

a. Inspection Scope

During the week of September 21, 2015, the inspectors performed an onsite review of Entergys records related to corrective actions taken in response to a Severity Level (SL) III Notice of Violation (NOV) issued to Indian Point on March 16, 2015. The NOV, involving a failure to provide accurate and complete information to the NRC on an operators license renewal application and meet the requirements of 10 CFR 50.9 and 10 CFR Part 55, is described in NRC Inspection Report 05000247 and 05000286/2015008 and is publically available in the NRCs Agencywide Document Access and Management System, accession number ML15075A328. The objectives of the inspection were to determine that adequate corrective actions have been implemented for the SL III NOV, root causes have been identified, generic implications have been addressed, and that Entergys programs and practices have been appropriately enhanced to prevent recurrence. The inspectors reviewed CRs, procedures, and relevant references to the NOV. The inspectors also interviewed management and staff personnel who participated in the CAP evaluation of the violations. The inspection criteria used during the inspection included the inspection guidance contained in IP 92702 and the performance attributes listed in Table 1 of IP 71152.

b. Findings

No findings were identified.

Entergys apparent cause evaluation (IP2-2014-4202) appropriately identified the apparent and contributing causes that resulted in the failure to provide accurate and complete information to the NRC on an operators license renewal application. Entergy performed a review of the extent of condition that ensured that necessary medical conditions are being identified and reported to the NRC. The inspectors corroborated this conclusion by sampling ten operators medical records during this inspection.

Entergys corrective actions included procedure changes and training of the necessary personnel. Entergy initiated CR-IP2-2015-00740 to ensure the adequacy of their corrective actions. The inspectors determined that adequate corrective actions had been taken to identify and report restricting medical conditions to the NRC to preclude recurrence.

.2 IP 92723, Follow Up on Inspection for Three or More Severity Level IV Traditional

Enforcement Violations in the Same Area in a 12-Month Period

a. Inspection Scope

The inspectors performed a review to assess Entergys evaluation of two SL IV violations and one SL III violation that occurred within the area of impeding the regulatory process from July 1, 2014, to July 1, 2015. The SL IV violations were documented in NRC inspection reports as:

(1) Non-cited violation (NCV)05000247/2014403-05 and NCV 05000286/2014403-05, involving a security-related reporting issue, and
(2) NCV 05000286/2015002-03, involving a failure to provide complete information in a report submitted per 10 CFR 50.73, Licensee Event Reports. The SL III violation was documented as enforcement action 14-180 in NRC Inspection Report 05000286/2015008 and is described in 4OA5.1.a.

The inspection objectives were to:

Provide assurance that the causes of multiple traditional enforcement violations are understood by Entergy.

Provide assurance that the extent of condition and extent of causes of multiple traditional enforcement violations are identified.

Provide assurance that Entergys corrective actions to traditional enforcement violations are sufficient to address the causes.

The inspectors reviewed the cause evaluation associated with each of the issues and the common cause analysis (CCA), CR-IP2-2015-04272, Indian Points IP 92723 Inspection Over-Arching Document. Additionally, the inspectors reviewed Entergys Pre-Inspection Assessment Worksheet and Snapshot Self-Assessment. The inspectors reviewed corrective actions to address the identified causes. Additionally, the inspectors held discussions with Entergy to ensure that the causes were understood and corrective actions were appropriate to address the causes.

b. Assessment

(1) Determine that Entergys Evaluation Identifies How Each of the Issues was Identified, How Long Each Issue Existed, and Prior Opportunities for Identification The inspectors determined that Entergys evaluation addressed how each of the issues was identified, how long they existed, and prior opportunities for identification.

Each issue was individually evaluated through Entergys CAP. Additionally, Entergy performed a collective evaluation for the two SL IV violations and one SL III violation through a pre-NRC inspection self-assessment.

(2) Determine that the Group of Traditional Violations Received an Evaluation at an Appropriate Level of Detail Using a Systematic Method(s) to Identify Cause(s)

The inspectors determined that the SL IV and SL III violations were reviewed collectively using a systematic process to identify any common causes. The inspectors also determined this review contained an appropriate level of detail. The inspectors verified that each violation was adequately evaluated in accordance with Entergys CAP requirements. Entergys CCA did not identify a clear common cause between the two SL IV violations and the SL III violation but identified three human performance aspects as apparent causes.

(3) Determine that the Evaluation Included a Consideration of How Prior Occurrences in the Same Traditional Enforcement Area (Willfulness, Regulatory Process, or Consequences) were Addressed by Entergy Entergy included additional SL IV violations from the previous five years in the area of impeding the regulatory process, which broadened the scope of their CCA. The inspectors noted that Entergys evaluation included a consideration of how prior occurrences in the area of impeding the regulatory process were addressed.

Entergys self-assessment of their CCA reviewed six previous SL IV traditional enforcement violations within the area of impeding the regulatory process which had occurred at Indian Point between September 1, 2010, and September 25, 2015, checking for repeat or similar problems and identified three human performance aspects as apparent causes. These aspects were identified as work practices, inattention to details, and misjudgment - mindset. Entergy also assessed the causes for individual violations. The CCA also considered operational experience regarding failure to make required reports to the NRC from other sites. The inspectors reviewed the previous SL IV violations to determine if they were due to a more fundamental concern involving weaknesses in Entergys CAP. The inspectors did not identify any commonality among the SL IV violations that suggested a fundamental weakness with Entergys CAP, and determined that evaluation of prior occurrences in the same traditional enforcement were adequately evaluated and addressed by Entergy.

(4) Determine that the Evaluation Addresses the Extent of the Condition and the Extent of Cause of the Problem The inspectors reviewed the individual CAP items for each of the SL IV and SL III violations, as well as the self-assessment. Entergy included a review of recent 10 CFR 50.59 evaluations and performance indicator data to verify that all required NRC reporting criteria were met. The inspectors determined that Entergys CAP process, augmented by the CCA, adequately addressed the extent of condition and the extent of cause in accordance with the procedural requirements for the individual violations, as well as collectively.
(5) Determine that Appropriate Corrective Action(s) are Specified for Each Cause Identified for the Group of Violations or That There Is an Evaluation Indicating That No Actions Are Necessary The inspectors noted that appropriate corrective actions were specified for the causes identified for each of the SL IV and SL III violations. Entergys CCA identified human performance as a common element in the SL IV and SL III violations considered in the CCA and addressed this through process and procedure changes, training for affected staff, and communication to Entergy personnel. The inspectors reviewed the corrective actions and identified no deficiencies.
(6) Determine that the Corrective Actions Have Been Prioritized with Consideration of the Regulatory Compliance The inspectors determined that corrective actions were adequately prioritized with consideration of regulatory compliance. Procedure EN-LI-102, Corrective Action Program, provided guidance for prioritizing corrective actions. A sample review conducted by the inspectors indicated that corrective actions were appropriately prioritized.
(7) Determine that a Schedule Has Been Established for Implementing and Completing the Corrective Actions The inspectors noted that a schedule was established for implementing and completing the corrective actions. Procedure EN-LI-102 provided guidance for establishing due dates for corrective actions. The inspectors conducted a sample review of completed and planned corrective actions and did not identify any discrepancies.
(8) Determine that Measures of Success Have Been Developed for Determining the Effectiveness of the Corrective Actions to Prevent Recurrence Measures of success were developed for determining the effectiveness of the corrective actions to prevent recurrence. Entergys CCA defined specific measures of success for the corrective actions addressing the SL IV and SL III violations. The specific measures of success focused on making all required reports.

c. Findings

No findings were identified.

4OA6 Meetings, Including Exit

On January 15, 2015, the inspectors presented the inspection results to Mr. Larry Coyle, Site Vice President, and other members of Entergy. The inspectors verified that no proprietary information was retained by the inspectors or documented in this report.

4OA7 Licensee-Identified Violations

The following violation of very low safety significance (Green) was identified by Entergy and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as an NCV. This issue was identified and documented in Entergys CAP as CR-IP2-2015-01985 and HQ-2015-00526, based on a previously identified NRC finding at another Entergy facility.

From 2010 to 2014, Indian Point made four shipments of radioactive material that contained category two levels of radioactive material quantity of concern but did not implement a transportation security plan for these shipments, which is contrary to the requirements of 49 CFR 172, Subpart I, Safety and Security Plans. This performance deficiency adversely affected the Public Radiation Safety cornerstone attribute of Program and Process based on inadequate procedures associated with the transportation of radioactive materials. This issue was documented in Entergys CAP as CR-IP2-2015-01985 and HQ-2015-00526. Corrective actions included revision of procedure EN-RW-106 and selection of a vendor to regularly review the federal register for regulatory changes that can impact plant operations.
