SUMMARY

Inspection Report 05000247/2017003 and 05000286/2017003; 07/01/2017 - 09/30/2017; Indian Point Nuclear Generating (Indian Point), Units 2 and 3; 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. The inspectors identified one finding of very low safety significance (Green), which was a non-cited violation (NCV). 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 April 29, 2015. Cross-cutting aspects are determined using IMC 0310, "Aspects within the Cross-Cutting Areas," dated December 4, 2014. All violations of U.S. Nuclear Regulatory Commission (NRC) requirements are dispositioned in accordance with the NRC's Enforcement Policy, dated November 1, 2016. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 6.

Cornerstone: Mitigating Systems

Green.

A self-revealing Green NCV of Technical Specification (TS) 5.4.1, "Procedures," with two examples was identified when Entergy failed to implement procedures to ensure correct system alignment for the nuclear instrumentation permissive interlock, P6, and auxiliary feedwater (AFW) flow transmitter, FI-1201. Entergy promptly corrected the alignment issues and entered them into their corrective action program (CAP) as condition report (CR)-IP2-2017-02193 for the P6 permissive interlock and CR-IP2-2017-02150 for the

AFW flow transmitter.

This performance deficiency is more than minor because it affects the configuration control attribute of the Mitigating System cornerstone to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, in both cases, the instrumentation was left disabled following maintenance such that they could not perform their safety functions required by TSs. Additionally, the first example was similar to IMC 0612, Appendix E, example 2.g, because Entergy changed plant modes from Mode 5 to Mode 2 without ensuring P6 was operable. The second example was similar to IMC 0612, Appendix E, examples 5.a and 5.b, because Entergy failed to return the AFW flow transmitter to service after the refueling outage. The inspectors assigned a cross-cutting aspect in the area of Human Performance, Work Management, because both examples demonstrated a failure in the planning, control, and execution of work, and a lack of coordination between work groups to ensure quality.

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 Entergy's 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, 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.

b. Findings

No findings were identified.

1R17 Evaluation of Changes, Tests, or Experiments

a. Inspection Scope

The inspectors verified that Entergy performed screens and evaluations of changes and tests in accordance with regulatory requirements and licensee implementing guidance. The inspectors reviewed safety evaluations to evaluate if changes to the facility or procedures, as described in the UFSAR, were reviewed and documented in accordance with 10 CFR 50.59 requirements. The safety evaluations reviewed were those completed by Entergy since the last NRC triennial 71111.17 inspection. In addition, the inspectors evaluated if Entergy was required to obtain NRC approval prior to implementing the changes. The inspectors interviewed Entergy personnel and reviewed supporting information including calculations, analyses, design change documentation, procedures, the UFSAR, TSs, and plant drawings to assess the adequacy of the safety evaluations. The inspectors compared the safety evaluations and supporting documents to the guidance and methods provided in Nuclear Energy Institute (NEI) 96-07, "Guidelines for 10 CFR 50.59 Evaluations," Revision 1 (ML003771157), as endorsed by NRC Regulatory Guide 1.187, "Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments" (ML003759710), and Draft Guidance DG-1330, "Guidance for Developing Principal Design Criteria for Non-Light Water Reactors" (ML16301A307), to

determine the adequacy of the safety evaluations.

The inspectors also reviewed a sample of screenings and applicability determinations for which Entergy concluded that a safety evaluation was not required. These reviews were performed to assess whether Entergy used a threshold for performing safety evaluations that was consistent with 10 CFR 50.59 standards. The inspectors included design changes, calculations, and procedure changes in the review. The screenings and applicability determinations were selected based on the safety significance, risk significance, and complexity of the change to the facility.

In addition, the inspectors compared Entergy's implementing administrative procedures used to control the screening, preparation, review, and approval of safety evaluations to the guidance referenced above to evaluate whether those procedures adequately implemented the requirements of 10 CFR 50.59.

The inspectors verified on a sampling basis that Entergy entered significant performance issues concerning their 10 CFR 50.59 program into their CAP. The inspectors further verified that Entergy developed appropriate corrective actions to address those issues.

b. Findings

No findings were identified.

1R18 Plant Modifications

Permanent Modifications

a. Inspection Scope

b. Findings

No findings were identified.

2RS5 Radiation Monitoring Instrumentation

a. Inspection Scope

The inspectors reviewed performance in assuring the accuracy and operability of radiation monitoring instruments used to protect occupational workers during plant operations and from postulated accidents. The inspectors used the requirements in 10 CFR Part 20, regulatory guides, American National Standards Institute (ANSI) 323A-1997, "Radiation Protection Instrumentation, Test and Calibration, Portable Survey Instruments," ANSI N323D-2002, "American National Standard for Installed Radiation Protection Instrumentation," ANSI N42.14-1991, "Calibration and Use of Germanium Spectrometers for the Measurement of Gamma-Ray Emission Rates of Radionuclides," and procedures required by TSs as criteria for determining compliance.

Inspection Planning The inspectors reviewed Entergy's UFSAR, radiation protection audits, records of in-service survey instrumentation, and procedures for instrument source checks and calibrations.

Walkdowns and Observations (1 sample)

The inspectors conducted walkdowns of plant area radiation monitors and continuous air monitors. The inspectors assessed material condition of these instruments and that the monitor configurations aligned with the UFSAR. The inspectors checked the calibration and source check status of various portable radiation survey instruments and contamination detection monitors for personnel and equipment.

Calibration and Testing Program (1 sample)

For the following radiation detection instrumentation, the inspectors reviewed the current detector and electronic channel calibration, functional testing results, alarm set-points, and the use of scaling factors: laboratory analytical instruments, whole body counter, containment high-range monitors, portal monitors, personnel contamination monitors, small article monitors, portable survey instruments, area radiation monitors, electronic dosimetry, air samplers, and continuous air monitors. The inspectors reviewed the calibration standards used for portable instrument calibrations and response checks to verify that instruments were calibrated by a facility that used National Institute of Science and Technology traceable sources.

Problem Identification and Resolution (1 sample)

The inspectors verified that problems associated with radiation monitoring instrumentation (including failed calibrations) were identified at an appropriate threshold

and properly addressed in the CAP.

b. Findings

No findings were identified.

4OA1 Performance Indicator Verification

.1 Mitigating Systems Performance Index (10 samples)

a. Inspection Scope

The inspectors reviewed Entergy's submittals for the following Mitigating Systems cornerstone PIs for the period July 1, 2016, through June 30, 2017:

Unit 2 Emergency AC Power System (MS06) High Pressure Injection System (MS07) Heat Removal System (MS08) Residual Heat Removal System (MS09) Cooling Water Systems (MS10)

Unit 3 Emergency AC Power System (MS06) High Pressure Injection System (MS07) Heat Removal System (MS08) Residual Heat Removal System (MS09) Cooling Water Systems (MS10)

To determine the accuracy of the PI data reported during those periods, the inspectors used definitions and guidance contained in NEI 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 7. The inspectors also reviewed Entergy's operator narrative logs, CRs, mitigating sy stems performance index derivation reports, event reports, and NRC integrated inspection re ports to validate the accuracy of the submittals.

b. Findings

No findings were identified.

.2 Emergency Preparedness Performance Indicators (3 samples)

a. Inspection Scope

The inspectors reviewed data for the following three EP PIs:

(1) drill and exercise performance,

(2) ERO drill participation, and

(3) ANS reliability. The last NRC EP inspection at Indian Point was conducted in the third calendar quarter of 2016. Therefore, the inspectors reviewed supporting documentation from EP drills and equipment tests from the third calendar quarter of 2016 through the second calendar

quarter of 2017 to verify the accuracy of the reported PI data. The review of the PIs was conducted in accordance with NRC Inspection Procedure 71151. The acceptance criteria documented in NEI 99-02, "Regulatory Assessment Performance Indicator Guidelines," Revision 7, was used as reference criteria.

b. Findings

No findings were identified.

.3 Occupational Exposure Control Effectiveness (1 sample)

a. Inspection Scope

The inspectors reviewed Entergy submittals for the occupational radiological occurrences PI for the first quarter 2017 through the second quarter 2017. The inspectors used PI definitions and guidance contained in NEI 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 7, to determine the accuracy of the PI data reported. The inspectors reviewed electronic personal dosimetry accumulated dose alarms, dose reports, and dose assignments for any intakes that occurred during the time period reviewed to determine if there were potentially unrecognized PI occurrences. The inspectors conducted walkdowns of various locked high and very high radiation area entrances to determine the adequacy of the controls in place for these areas.

b. Findings

No findings were identified.

Occurrences (1 sample)

a. Inspection Scope

The inspectors reviewed Entergy submittals for the radiological effluent TS/Offsite Dose Calculation Manual radiological effluent occurrences PI for the first quarter 2017 through the second quarter 2017. The inspectors used PI definitions and guidance contained in NEI 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 7, to determine if the PI data was reported properly. The inspectors reviewed the public dose assessments for the PI for public radiation safety to determine if related data was accurately calculated and reported.

The inspectors reviewed the CAP database to identify any potential occurrences such as unmonitored, uncontrolled, or improperly calculated effluent releases that may have impacted offsite dose. The inspectors reviewed gaseous and liquid effluent summary data and the results of associated offsite dose calculations to determine if indicator results were accurately reported.

b. Findings

No findings were identified.

4OA2 Problem Identification and Resolution

.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 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.

b. Findings

No findings were identified.

.2 Annual Sample:

Failure of Baffle Former Bolts Due to Irradiation Assisted Stress Corrosion Cracking

a. Inspection Scope

The inspectors performed an in-depth review of Entergy's corrective actions, materials testing report, and root cause evaluation associated with CR-IP2-2016-02348 for baffle former bolts found with indications of degradation during 2RFO22. This NRC inspection was performed as a follow-up to the preliminary root cause of the Unit 2 baffle former bolt failures after the materials testing of bolts removed from the reactor vessel was

completed.

Entergy discovered an unexpected number of degraded baffle former bolts through planned examinations during the Unit 2 refueling outage and reported the issue to the NRC as Event Notification 51829 on March 29, 2016, because the as-found number and location of degraded bolts represented an unanalyzed condition. Entergy staff completed corrective actions to replace all of the potentially degraded baffle former bolts on Unit 2; and during replacement activities, Entergy staff quarantined and shipped a population of removed baffle former bolts to a materials testing facility to confirm the cause of the bolt degradation.

The inspectors assessed Entergy's problem identification threshold, cause analyses, compensatory actions, and the prioritization and timeliness of Entergy's corrective actions to determine whether Entergy staff were properly identifying, characterizing, and correcting problems associated with this issue and whether the planned or completed corrective actions were appropriate. The inspectors compared the actions taken to Entergy's CAP and the requirements of 10 CFR Part 50, Appendix B. The inspectors discussed the results of the materials testing with engineering personnel to assess the root cause evaluation and to further assess the effectiveness of the implemented corrective actions.

b. Findings and Observations

No findings were identified.

Entergy staff preliminarily determined the root cause of the degraded and failed baffle former bolts was primarily due to irradiation-assisted stress corrosion cracking (IASCC)in combination with stress fatigue. IASCC is a cracking mechanism that occurs over a long period of time when susceptible metals are exposed to neutron radiation from the reactor core and stresses as part of normal design and operation. This preliminary determination was based on industry operating experience related to baffle former bolt failures in both foreign and domestic plants. Entergy staff provided a sample of baffle former bolts removed from the Unit 2 reactor vessel to a metallurgical laboratory for detailed failure analysis in order to confirm the root cause. Fractography, which is the study of a materials fracture surface, was used to determine the cause of the observed baffle former bolt failures. The fractography test report concluded that all of the cracking initiated from an intergranular (IG) mode and that the cracking propagated to failure from IG or a combination of IG and transgranular. The significant amount of IG cracking, including numerous IG initiation sites, strongly indicated IASCC was fundamental to the failures, and the portions of observed transgranular cracking were attributed to fatigue based on the crack morphology. These test results confirmed that cracking first initiated by IASCC and then propagated by cyclical/fatigue loading caused by normal and transient operational loading.

The inspectors reviewed Entergy's root cause evaluation and the fractography report of the removed Unit 2 baffle former bolt failures. The inspectors concluded that Entergy staff conducted an appropriate review to identify and confirm the causes of the degraded and failed baffle former bolts. Entergy revised their Indian Point reactor vessels internals program to perform ultrasonic inspections of 100 percent of the original baffle former bolts during each of the subsequent refueling outages as well as a general visual inspection of the baffle structure, including any replaced bolts. The inspectors noted that the re-examinations of the baffle former bolts were planned to be conducted more frequently than the recently issued industry program guidance. Based on discussions with engineering staff, the inspectors learned that Entergy cancelled its initial plans to perform a modification to convert the Unit 2 core barrel assembly from a "downflow" to an "upflow" configuration. The inspectors determined Entergy's overall response to the issue was commensurate with safety significance, was timely, and included appropriate corrective actions.

The inspectors also reviewed information from Unit 3 baffle former bolt examinations performed during its spring 2017 refueling outage and determined that Entergy had performed a technical evaluation prior to the outage that bounded the as-found conditions. This evaluation used the approach documented in Westinghouse Nuclear Safety Advisory Letter NSAL-16-1, dated July 5, 2016, to assess the impact of significantly clustered bolt failures during a design basis accident. Because the as-found Unit 3 baffle former bolt condition was analyzed and determined not to significantly degrade plant safety, the condition was not reportable.

(Closed) Unresolved Item (URI) 05000247/2016-001-01: Baffle Former Bolts with Identified Anomalies On March 29, 2016, Entergy reported to the NRC that the level of degradation of Unit 2 baffle former bolts was a condition not previously analyzed. The NRC opened a URI to determine whether there was a performance deficiency associated with the degraded baffle former bolt condition. In April and May 2016, the inspectors conducted additional inspections at Unit 2 to review the ultrasonic testing procedure and results from the examination of the baffle former bolts and to review video recordings of the reactor vessel during previous refueling outages. The inspectors conducted the inspection in this report as a follow-up to review Entergy's materials testing report of baffle former bolts removed from Unit 2 as part of the bolt replacement corrective actions and to assess the test results impact on the root cause evaluation. The inspectors also evaluated Entergy's response to the baffle former bolt examination results from Unit 3 during its spring 2017 outage. The inspectors determined that Entergy took appropriate action to confirm the root cause of the degraded baffle former bolts. The inspectors did not identify any findings during the follow-up inspections for the URI. This URI is closed.

.3 Annual Sample:

Reactor Vessel Head O-ring Leaks

a. Inspection Scope

The inspectors performed an in-depth review of Entergy's evaluation and corrective actions associated with repeated reactor coolant system (RCS) leakage through the reactor vessel head O-rings. The inspectors reviewed CRs and corrective actions associated with the eight reactor vessel head O-rings leaks that had occurred at Indian Point since 2003. Specifically, the inspectors reviewed the corrective actions to verify they were addressing the identified conditions adverse to quality. The inspectors reviewed Entergy's maintenance history records and causal analyses.

The inspectors assessed Entergy's problem identification threshold, cause analyses, extent of condition reviews, compensatory actions, and the prioritization and timeliness of corrective actions to determine whether Entergy was appropriately identifying, characterizing, and correcting problems associated with this issue and whether the planned or completed corrective actions were appropriate. The inspectors compared the actions taken to the requirements of Entergy's CAP and 10 CFR Part 50, Appendix B.

In addition, the inspectors performed field walkdowns and interviewed engineering personnel to assess the effectiveness of the implemented corrective actions.

b. Findings and Observations

No findings were identified.

The reactor pressure vessel (RPV) is designed to be sealed by two large diameter (different size), concentric, circular, silver-coated, stainless steel gasket O-rings. These O-rings are seated in machined grooves between the RPV head and the vessel. Two new O-rings are routinely installed each outage when the RPV head is bolted closed. The inner O-ring normally maintains the pressure seal for the RCS boundary. The outer O-ring is a pre-installed redundant spare that is designed to be used if the inner O-ring leaks. Leakage through the inner O-ring can be identified via a leakoff line between the inner and outer O-rings. The operators can place the outer O-ring in service by closing the leakoff line. This transfers the RCS boundary sealing surface to the outer O-ring. TS 3.4.13, "RCS Operational Leakage," establishes limits for the leak rate for identified and unidentified RCS leakage. Leakage through the RPV O-rings is not classified as "pressure boundary leakage" under TS 1.1, "Definitions," because the leakage is past a mechanical joint (gasket) and not through a "non-isolable fault in an RCS component body, pipe wall or vessel wall." Leakage through the O-rings into containment would be measured and compared to the limits in TS 3.4.13.

The inspectors reviewed CRs and corrective actions associated with the eight reactor vessel head O-rings leaks that occurred since 2003, when a design change to the O-rings occurred. Leakage through the O-rings prior to the design change may have been in part caused by the original design. In each case when both the inner and outer O-rings leaked, Entergy identified and monitored the leakage at a very low level and took prudent, conservative action to shut down the plant before approaching the TS limit to effect repairs and identify causal factors that potentially led to the leakage. Corrective actions since the design change have been primarily focused on revisions to procedures and processes. Changes to procedures 2-REF-002-GEN and 3-REF-002-GEN included new instructions to manually clean and dry the vessel flange seating surface prior to landing the head instead of relying on the underwater flange-cleaning machine. Additional revisions directed the use of a "star" pattern when torqueing the O-ring retainer clips, use of a feeler gauge to verify the O-ring was centered in the groove, performance of a second verification, and ensuring an O-ring handling rig was used for installation. Corrective actions also incl uded replacement of the O-rings with new O-rings during the next opportunity. The most recent corrective actions were implemented to prevent changes in residual heat removal flow from disrupting the O-ring seal surfaces prior to final bolting of the RPV head.

Corrective actions to address the various causal factors over the years have not been completely effective at preventing recurrence of the issue. This is acceptable per Entergy's CAP because each leak is characterized as a condition adverse to quality, vice a significant condition adverse to quality. Entergy has the ability to monitor for leakage and take actions to maintain compliance with their TS. Leakage through the O-rings has not challenged the limits of TS 3.4.13. Both Units 2 and 3 are currently operating on the outer O-rings with no measurable leakage.

In review of all the corrective actions taken since 2003, the inspectors noted that Entergy had not taken detailed depth measurements of the RPV flange seating surface degradation since 2015, when surface defects identified were small. These surface defects had been noted again during the May 2017 outage to repair the leaking O-rings.

However, this degradation had been visually assessed to be minor in nature and the replacement O-ring was evaluated as being capable of deforming to seal these minor defects. Entergy is presently planning to conduct laser measurement and mapping of these defects during the next refueling outage on each unit.

Finally, the inspectors also noted that procedure EN-HU-106, "Procedure and Work Instruction Use and Adherence," states that technical procedures should be designated "continuous use" if the activity is complex or is performed infrequently to ensure that the procedural steps are performed as written in stepwise sequence. Although the reactor vessel head O-ring replacement and head installation are complex activities typically performed only once per cycle, the governing procedures are designated as "reference use." EH-HU-106 also defines a "continuous use" procedure, "for complex or infrequent work activities for which consequences of an improper action could have immediate, possibly irreversible impact on safety, production or reliability." Though the usage designation of 2-REF-GEN-002 and 3-REF-GEN-002 has not been identified as causal to any of the leaks, inspectors determined that Entergy should further evaluate the categorization of the RPV head installation procedure to ensure it meets their requirements and expectations and ensures that previous corrective actions continue to be implemented as intended.

.4 Annual Sample:

EDG Voltage Control/Corrective Actions for Automatic Voltage Regulator (AVR) Cards

a. Inspection Scope

The inspectors performed an in-depth review of Entergy's apparent cause analysis and corrective actions associated with CR-IP2-2016-01260 and CR-IP3-2016-01370. Specifically, on March 7 and 10, 2016, Unit 2 experienced a loss of vital bus power during a refueling outage. These events were caused by a degraded AVR card on the 23 EDG. A review of past operating experience identified a 10 CFR 50.21 report from 2007 that had identified the potential for a solder joint on the AVR card to degrade and result in the loss of automatic voltage control. Entergy had not taken the remedial actions recommended in the 10 CFR 50.21 report (ML072750470) prior to the failures.

After experiencing the loss of vital bus on Unit 2, Entergy implemented the recommended corrective actions for both units. The inspectors reviewed the

effectiveness of the implementation of the corrective actions in this inspection.

The inspectors assessed Entergy's problem identification threshold, cause analyses, extent of condition reviews, compensatory actions, and the prioritization and timeliness of Entergy corrective actions to determine whether Entergy was appropriately identifying, characterizing, and correcting problems associated with this issue, and whether the planned or completed corrective actions were appropriate. The inspectors compared the actions taken to the requirements of Entergy's CAP and 10 CFR Part 50, Appendix B. In addition, the inspectors performed field walkdowns and interviewed engineering personnel to assess the effectiveness of the implemented corrective actions.

b. Findings and Observations

No findings were identified.

On March 7, 2016, Unit 2 experienced a loss of vital bus when 23 EDG failed to run during a surveillance test. This failure was initially attributed to failed overcurrent trip relays which were replaced. Subsequently, on March 10, 2016, a second loss of the 23 EDG occurred which resulted in a loss of power to all vital buses and a loss of shutdown cooling. The preliminary causal analysis indicated that the trip was caused by a degraded solder joint on the AVR card resulting in a loss of voltage control for the 23 EDG generator and an over-current condition. After analysis in the laboratory, Entergy determined that they had failed to take recommended remedial actions from a

10 CFR 50.21 report (ML072750470) from 2007 to identify and remediate the degraded solder joint prior to failure. This event was initially documented in URI 05000247/2016001-06, 23 Emergency Diesel Generator Automatic Voltage Regulator Failure. The inspectors subsequently documented a Green NCV,05000247/2016003-02, Missed Inspections on Automatic Voltage Regulator Cards Results in 23 Emergency Diesel Generator Failure to Run. In October 2016, the inspectors identified that Entergy had not promptly remediated the same conditions on the Unit 3 EDG AVR cards and previously documented this issue under NCV 05000286/2016003-03, Untimely Corrective Actions to Address Degraded Automatic Voltage Regulator Card (on the Unit 3 EDGs). The results of the inspections indicated that the L1 magnetic amplifier solder joints on the AVR cards were degraded for both units.

Entergy submitted Licensee Event Report (LER) 05000247/2016-002-00, Automatic Actuation of Emergency Diesel Generators Due to 480 VAC Bus Undervoltage Condition and Loss of Residual Heat Removal While in Cold Shutdown, by IPEC Letter NL-17-030 dated May 6, 2016. This LER reported that the failure of the 23 EDG on March 10, 2016, was caused by the degraded solder joint on the AVR card but did not reach a conclusion regarding the failure of the 23 EDG on March 7, 2016. Further analysis resulted in the determination that both failures (March 7 and 10, 2016) were most likely the result of a degraded solder joint on the AVR card. On February 28, 2017, Entergy revised LER 05000247/2016-002-01, Automatic Actuation of Emergency Diesel Generators Due to 480 VAC Bus Undervoltage Condition and Loss of Residual Heat Removal While in Cold Shutdown, by IPEC Letter NL-17-030 dated February 28, 2017, to reflect this analysis.

The inspectors determined that Entergy had completed all required remedial actions specified by the vendor on both units. The AVR cards for all EDGs were either replaced or repaired. A preventive maintenance requirement was established to inspect the AVR card solder joints at the period recommended by the vendor for solder joint degradation. Entergy also reviewed the applicability of this operating experience by conducting a thorough extent of condition assessment for AVRs on other generating assets such as the Appendix R diesels and the main generators.

.5 Annual Sample:

Measuring and Testing Equipment (M&TE) Program

a. Inspection Scope

The inspectors examined the facilities for the M&TE, the automated tool inventory control and tracking system, and the process for checking out and checking in M&TE. The inspectors reviewed the fleet and site procedures as well as CRs relating to M&TE, including a root cause evaluation from 2014 which was revised as recent as 2016. The inspectors interviewed employees about the M&TE program. The inspectors reviewed a sample of equipment as well as components for consistency with the M&TE program.

The inspectors verified that Entergy's FSAR commitments relative to the control of M&TE are in accordance with regulatory requirements and are being met. Additionally, the inspectors verified that Entergy has addressed criteria and responsibility for determination of calibration frequency, a method of identification of each device and its calibration status, and a method for documenting M&TE calibration history.

b. Findings and Observations

No findings were identified.

The inspectors generally found that Entergy demonstrated adequate commitment to M&TE implementation and oversight, individual contributors followed M&TE program procedures, and fleet and site written guidance provided clear guidance. Inspectors also generally found that the program had clearly defined roles, responsibilities, and accountability for program implementation.

4OA3 Follow Up of Events and Notices of Enforcement Discretion

.1 Plant Events

a. Inspection Scope

For the plant event listed below, the inspectors reviewed and/or observed plant parameters, reviewed personnel performance, and evaluated performance of mitigating systems. The inspectors communicated the plant event to appropriate regional personnel and compared the event details with criteria contained in IMC 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 50.72 and 50.73. The inspectors reviewed Entergy's follow-up actions related to the event to assure that Entergy implemented appropriate corrective actions commensurate with their safety significance.

Unit 3 Excessive bonnet leakage from chemical volume control system valve on June 11, 2017 (Event Notification 52801)

b. Findings

Introduction.

A self-revealing Green NCV of TS 5.4.1 with two examples was identified because Entergy did not implement procedures to ensure correct system alignment for the nuclear instrumentation permissive interlock, P6, and AFW flow transmitter, FI-1201.

Description.

Entergy failed to properly restore some instrumentation functions to service following the completion of surveillance testing or troubleshooting as required. This has resulted in some instrumentation safety functions not being readily available when required. Two recent self-revealing exam ples of components being improperly restored to service were analyzed by NRC inspectors.

Example 1: Nuclear Instrumentation Permissive Interlock, P6

On June 27, 2017, while Unit 2 was in Mode 3, Instrumentation and Control (I&C)technicians performed 2-PT-V63A, Reactor Protection System Logic Train 'A' Partial Function Test. This testing procedure is required to conform to standards as set forth in Section 5.4.1 of the Indian Point Unit 2 TSs, specifically complying with Regulatory Guide 1.33, Revision 2. This test involved verification of the P6 permissive interlock setpoint, which enables the reactor operators to manually block the source range

high-flux trip when intermediate range channels are greater than 10

-10 amps. The operators can then manually de-energize source range instruments in order to continue raising power above the source range high flux trip setpoint on the source range monitors once reactor power is high enough to use the intermediate range monitors and overlap has been verified. The manual block of the high source range reactor trip is procedurally required during reactor start up. The block setpoint overlaps with the intermediate range detector lower range of 2.5 x 10

-11 amps and is meant to ensure verification of intermediate range detector operability prior to raising power. The safety function of the P6 permissive interlock is to automatically re-engage the source range high-flux trip automatically if power subsequently decreases below the intermediate range detector lower range after it has been manually blocked.

Upon completing the work in Mode 3, the technicians left the P6 permissive interlock disabled. The reactor protection system (RPS) switch lineup to re-enable the P6 permissive circuit was not completed prior to entry into Mode 2 resulting in a tripped state of both channels of the P6 permissive interlock during the subsequent startup. On June 28, 2017, while in Mode 2 during reactor startup, when power was raised above the

P6 permissive enabled setpoint (1 x 10

-10 amps), the source range trip permissive interlock failed to activate resulting in the inability of the operators to manually block the source range instruments. The operators reinserted the control rods to bring the unit back to Mode 3. Upon identification of the misaligned switches, operators declared the P6 permissive inoperable and entered the issue into the CAP as CR-IP2-2017-02193.

Entergy subsequently enabled the P6 permissive switches, completed the reactor startup, and performed an extent-of-condition evaluation, which verified that no other RPS logic switches were misaligned.

Example 2: AFW Flow Transmitter, FI-1201 On March 6, 2017, I&C technicians performed maintenance and testing on the 22 SG AFW flow indicator (FI-1201). During this maintenance activity, isolation of the high and low isolation valves and opening of the equalizing valve to relieve pressure was required. The transmitter was then restored to service with the exception of filling and venting.

During this time, the root valves were tagged out and the source of water was isolated, preventing proper filling and venting. The I&C supervisor discussed the restoration of the transmitter with the operations shift manager, and it was agreed that operations would complete restoration of the transmitter when the tag-out was removed. I&C noted this and marked "N/A" for the steps required to return the transmitter to service, which is permitted by procedure. However, the procedure also specifies that a second knowledgeable individual must agree with the steps or sections marked "N/A" and initial and date each step or section prior to considering the document complete. The I&C supervisor did not obtain the shift manager's initials prior to considering the document complete and, ultimately, Operations did not restore the transmitter to service by filling and venting.

On June 26, 2017, while in Mode 3 immediately after manually tripping the reactor, operators received an alarm that there was no flow from FI-1201. After immediate verification to determine feed flow, Entergy determined this alarm was due to instrument failure. Upon further investigation, Entergy determined that FI-1201 was not filled and vented, resulting in inoperability.

Analysis.

Failing to correctly align plant instrumentation per plant procedures following maintenance is a performance deficiency because it was reasonably within Entergy's ability to foresee and correct and should have been prevented. The performance deficiency is more than minor because it affects the configuration control attribute of the Mitigating System cornerstone to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage).

Specifically, in both cases, the instrumentation was left disabled following maintenance such that they could not perform their safety functions required by TSs.

Additionally, the first example was similar to IMC 0612, Appendix E, example 2.g, because Entergy changed plant modes from Mode 5 to Mode 2 without ensuring P6 was

operable per TS 3.3.1, "RPS Instrumentation," which was in violation of TS 3.0.4. NRC inspectors determined this example is of very low safety significance (Green) using IMC 0609, Appendix A, "Mitigating Systems - Mi tigating SSCs and Functionality," because it did not involve a deficiency in the design or qualification of the SSC, did not represent the loss of function, did not exceed the TS allowed outage time, and did not represent loss of function for one or more non-TS trains of equipment designed as high safety significance.

The second example was similar to IMC 0612, Appendix E, examples 5.a and 5.b, because Entergy failed to return the AFW flow transmitter to service after the refueling outage and resulted in a violation of TS 3.3.3, "Post Accident Monitoring Instrumentation." NRC inspectors determined this example is also of very low safety significance (Green) using IMC 0609, Appendix A, "Mitigating Systems - Mitigating SSCs and Functionality," because it did not involve a deficiency in the design or qualification of the SSC, did not represent the loss of function, and did not represent loss of function for one or more non-TS trains of equipment designed as high safety significance. Specifically, though the flow indicator did exceed its TS allowed outage time, it did not result in loss of function or operability of the safety-related AFW system.

This finding had a cross-cutting aspect in the area of Human Performance, Work Management, because each example exhibited a failure in the planning, control, and execution of work and a lack of coordination between work groups that would have prevented the performance deficiency. Specifically, the work process should ensure individuals are aware of plant status, the nuclear safety risks associated with work in the field, and other parallel station activities [H.5].

Unit 2 TS 5.4.1, "Procedures," requires, in part, that written procedures shall be implemented covering listed activities, in Regulatory Guide 1.33, Appendix A, Revision 2. Section 3 of Appendix A to Regulatory Guide 1.33 specifies, in part, that instructions including energizing, filling, venting, and changing modes of operation should be prepared and appropriate for the reactor protection and AFW systems. 2-PT-V63A, "Reactor Protection Logic Train 'A' Partial Function Test," and 2-PT-V63B, "Reactor Protection Logic Train 'B' Partial Function Test," are the implementing procedures for surveillance testing as required by TS 3.3.1. 2-PC-EM8A, "Auxiliary Feedwater Flow Instruments," Revision 5, is the procedure for calibrating the component as required by TS 3.3.3, "Post Accident Monitoring." OAP-019, "Component Verification and System Status Control," Revision 7, is the procedure which specifies configuration control of plant components.

Contrary to the above, Entergy did not properly implement the procedures used to calibrate and align these instruments. Specifically, Entergy failed to properly implement procedures to calibrate and align the RPS logic system, P6 permissive interlock, which rendered the interlock inoperable from June 26, 2017, to June 27, 2017, and the AFW flow transmitter, which rendered it inoperable from March 6, 2017, to June 26, 2017.

Upon discovery of each inoperability, Entergy corrected the system configuration and entered the issues into their CAP as CR-IP2-2017-02193 and CR-IP2-2017-02150, respectively.

This violation is very low safety significance (Green) and is being treated as an NCV, consistent with Section 2.3.2.a of the Enforcement Policy. (NCV 05000247/2017-003-01, Component Misalignments Following Scheduled Maintenance)

.2 (Closed) LER 05000247/2016-004-00:

Unanalyzed Condition Due to Degraded Reactor Baffle Former Bolts

In March 2016, Entergy performed examinations of the Unit 2 reactor vessel internal components during 2RFO22 as part of scheduled license renewal activities and discovered a greater than expected amount of degraded baffle former bolts through visual and ultrasonic examinations. Entergy determined that the number and location of baffle former bolts did not meet the acceptance criteria provided in the pre-outage bolt pattern analysis to support plant startup, and as a result, Entergy reported this as an unanalyzed condition to the NRC as Event Notification 51829 on March 29, 2016. The inspectors performed inspections documented in Section

4OA2 of this report and in Section 4OA2 of NRC Inspection Report 05000247/2016002 (ML17089A245) as a follow-up to the event.

The inspectors also reviewed piping analyses specific to Indian Point to verify assumptions made in the safety significance assessment of the as-found baffle former bolt condition at Unit 2. The inspectors did not identify any findings or violations of NRC requirements during the revi ew of this LER. This LER is closed.

.3 (Closed) LER 05000247/2017-002-00:

Auxiliary Feedwater Flow Indication Inoperable for Longer Than the Allowed Technical Specification Completion Time Due to Failure to Complete Restoration Following Calibration On June 26, 2017, following a reactor trip, Entergy identified that the 22 SG AFW flow indicator (FI-1201) was inoperable. The flow indicator is used for post-accident monitoring to ensure adequate heat removal via the SG. The direct cause was due to I&C technicians tagging out the root valves, isolating the source of water, and thus preventing proper filling and venting of the transmitter (FI-1201). The apparent cause was poor communications. The status of the transmitter and the need to be filled and vented following tag-out removal was not logged or turned over to the on-coming operations shift in accordance with procedures. The inspectors reviewed Entergy's actions and reportability criteria associated with LER 05000274/2017-002-00, which was submitted to the NRC on August 24, 2017. The enforcement aspects of this issue are discussed in Section 4OA3.1 of this report. The inspectors did not identify any other issues during the review of the LER. This LER is closed.

.4 (Closed) LER 05000247/2017-003-00:

Technical Specification Violation of Section 3.3.1 RPS Instrumentation On June 27, 2017, during reactor startup, power was raised from Mode 3 to Mode 2 and above the P6 (intermediate range neutron flux) interlock with the P6 switches in the wrong position. The P6 interlock is used to block the source range high-flux trip when power level is above 10

-10 amps in the intermediate range detectors. The direct cause was due to I&C technicians not restoring test permissive intermediate range switches 1/N35D and 1/N36D to their proper position during surveillance testing as required by procedure. The apparent cause was poor communications. The responsible supervisor and maintenance leadership did not provide sufficient oversight or guidance, and the test procedure 2-PT-V063A is not aligned with writer's guide best practices. The inspectors reviewed Entergy's actions and reportability criteria associated with LER 05000274/2017-003-00, which was submitted to the NRC on August 24, 2017. The enforcement aspects of this issue are discussed in Section 4OA3.1 of this report. The inspectors did not identify any other issues during the review of the LER. This LER is

===closed.

.1 Institute of Nuclear Power Operations (INPO) Operations Program Accreditation Report Review

a. Inspection Scope

The inspectors reviewed the final report for the INPO Operations Training Programs Accreditation of Units 2 and 3 conducted in July 2017. The inspectors reviewed the

report to ensure that any issues identified were consistent with NRC perspectives of Entergy performance and to determine if INPO identified any significant safety issues that required further NRC follow-up.

b. Findings

No findings were identified.

.2 (Discussed) VIO 05000247/2016003-07:

Inadequate Control of Floor Drains to Minimize Groundwater Contamination (EA-16-193)

On February 16, 2017, Entergy replied to Notice of Violation 05000247/2016003-07, Inadequate Control of Floor Drains to Minimize Groundwater Contamination. The corrective actions identified by Entergy included repairing the floor drain system and fuel storage building (FSB) sump pump 28 and inspecting and cleaning the floor drain systems in Units 2 and 3. Additionally, Entergy tested and placed in service recovery well 1 (RW-1) in the area of highest groundwater tritium concentration. Review of Entergy documentation indicates repairs to the FSB sump pump 28 were completed; however, the backflow inhibitor valve, present in the original drawings for the sump but never installed, has still not been installed. This activity is scheduled for the fourth quarter 2017. Also not scheduled until the fourth quarter 2017 is the installation of a permanent sealant in the FSB subfloor, which was the location for two of the 2016 groundwater leaks. Regarding inspection of the floor drains, Entergy records indicate that sixteen identified drains have not been examined due to a lack of access; and two floor drains could not be located in Unit 2. In Unit 3, seven identified drains have not been examined due to a lack of access; and one floor drain could not be located.

Preventive maintenance activities have been created to periodically clean the floor drains, with a specified frequency of six years, which puts the next cleaning beyond the announced plant shutdown date. This item remains open pending completion of the backflow valve and FSB subfloor modifications, and the inspections for all remaining floor drains in the radiological controlled area at Units 2 and 3 (excluding those in the

containment).

4OA6 Meetings, Including Exit

On October 20, 2017, the inspectors presented the inspection results to Mr. Anthony Vitale, Site Vice President, and other members of Entergy's staff. The inspectors verified that no proprietary information was retained by the inspectors or documented in

this report.
