SUMMARY

IR 05000247/2013003, 05000286/2013003; 04/01/13 - 06/30/13; Indian Point Nuclear

Generating Units 2 and 3; Maintenance Risk Assessments and Emergent Work Control,

Problem Identification and Resolution, and Follow-Up of Events and Notices of Enforcement Discretion.

This report covered a three-month period of inspection by resident inspectors and announced inspections performed by regional inspectors. The inspectors identified three findings of very low safety significance (Green), which were non-cited violations (NCVs). The significance of most findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red)and determined using Inspection Manual Chapter (IMC) 0609, Significance Determination Process, dated June 2, 2011. Cross-cutting aspects are determined using IMC 0310,

Components Within Cross-Cutting Areas, dated October 28, 2011. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy, dated January 28, 2013. The NRCs 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 Title 10 of the Code of Federal Regulations (10 CFR) 50.65(a)(4), requirements for monitoring the effectiveness of maintenance, when Entergy did not assess and manage the risk associated with reactor protection testing with Unit 3 below normal operating pressure. Specifically, on March 27, 2013, with Unit 3 just having entered Mode 3 and while raising reactor coolant system (RCS) temperature, required risk management actions were not taken regarding a reactor protection system test, and due to a problem with the test equipment, a low pressure safety injection (SI)actuated. Entergy operators took action to mitigate the SI, and the event was entered into the corrective action program (CAP) as CR-IP3-2013-2115. A root cause evaluation was initiated to determine the acceptability of conducting this test with the plant at low pressure in Mode 3 and address extent of condition.

The finding was more than minor because it was associated with the configuration control attribute of the Mitigating Systems cornerstone and affected the cornerstone objective of ensuring the availability of systems that respond to initiating events to prevent undesirable consequences. In addition, in accordance with IMC 0612, Appendix E, Example 7.f, had the risk assessment for the testing been done using Entergys risk procedure, the assessment would have determined the impairment of the low pressure SI interlocks and would have placed the plant in an administrative higher risk condition (Orange). The finding was evaluated using IMC 0609, Appendix K, Maintenance Risk Assessment and Risk Management Significance Determination Process, and determined to be of very low safety significance (Green) when the risk assessment was performed correctly with the resulting actual incremental core damage frequency deficit determined to be very small, less than 1E-6. The inspectors determined this finding had a cross-cutting aspect in Human Performance, Work Control, when Entergy personnel did not take risk insights, job site conditions such as the plant pressure, technical specification requirements, and an inaccurate pressurizer level indication into consideration when preparing for testing along with the need for contingencies. [H.3.(a)] (Section 1R13)

Green.

The inspectors identified an NCV of 10 CFR 50, Appendix B, Criterion XVI,

Corrective Action, when Entergy failed to correct a condition adverse to quality associated with the Unit 3 pressurizer safety valves (PSVs). Specifically, following valve lift setpoint failures in 2005 and 2008, Entergy did not complete a cause determination and establish corrective actions. As a result, a PSV (PCV-468) removed from Unit 3 in 2011, lifted at higher than its setpoint pressure due to spring fatigue. Following the 2011 failure, Entergy performed a cause investigation and initiated a corrective action to include spring rate testing in the inspection of the safety valves.

The finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. In accordance with IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, the finding screened to be of very low safety significance (Green), when all screening questions were answered no. The inspectors determined that no cross-cutting aspect was applicable to this performance deficiency because this finding was not indicative of current licensee performance. (Section 4OA2)

Green.

The inspectors identified an NCV of 10 CFR 50, Appendix B, Criterion V,

Procedures, when Entergy did not maintain appropriate written procedures for responding to an inadvertent SI on Unit 3 when below the normal operating RCS temperature. As a result, operators did not comply with procedure requirements when responding to an inadvertent SI event on March 27, 2013. During a review of the event by the inspectors, procedure deficiencies were identified which have the potential to lead to a more significant safety concern. Entergy personnel documented the March 27 event in their CAP as CR-IP3-2013-2115 and initiated a root cause evaluation.

The finding was more than minor because, if left uncorrected, the procedure deficiencies have the potential to lead to a more significant safety concern related to exceeding vessel integrity pressure limitations if a charging pump was started in solid conditions below 380°F.

In accordance with IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, the finding screened to be of very low safety significance (Green), when all screening questions were answered no. The finding was assigned a cross-cutting aspect in the area of Human Performance, Resources, because Entergy staff did not ensure that design documentation and procedures were adequate to assure nuclear safety. H.2(c) (Section 4OA3)

b. Findings

Introduction:

The inspectors identified a Green NCV of 10 CFR 50.65(a)(4) when Entergy did not assess and manage the risk associated with reactor protection testing with the plant below normal operating pressure. Risk management precautions were not assigned as required by Entergys on-line risk procedure, and due to a problem with the test equipment, a low pressure SI actuated.

Description:

On March 27, 2013, within one hour after entering Mode 3 and during heatup to normal operating pressure and temperature, Entergy initiated plant test 3-PT-M13B, Reactor Protection Logic Channel Functional Test (Monthly). The test required the four pressurizer pressure signals to be greater than 1930 psig, but with the plant at a lower pressure, directed the four pressure channels be provided with false signals using test potentiometers. Operators did not recognize that providing false pressure signals to all three engineered safety feature actuation system (ESFAS)pressure instruments made the ESFAS interlocks inoperable and the appropriate technical specification action was not entered. Also, the operators did not recognize that automatic operation of the reactor coolant power operated relief valves (PORVs) was disabled when the pressure channels were defeated. Entergy attempted a risk assessment of the testing in accordance with their procedure EN-WM-104, On Line Risk Assessment, which was in effect when the unit entered Mode 3, but the test, 3-PT-M13B, was dropped from the risk assessment after discussion with the risk analyst because the resulting higher risk orange condition was intended for at-power situations.

The effect of the test on the pressure channels, the ESFAS interlocks, and the PORVs were not reviewed with the risk analyst nor included in the resulting assessment. The risk assessment procedure specified an evaluation of plant integrated risk which would consider technical specification limitations, but this was not done when the outage group did not recognize the risk management procedure as being in effect.

When false signals were inserted into the pressure channels, plant pressure was approximately 1100 psi and being slowly increased. Precise pressurizer level indication was not available because neither the cold calibrated instrument nor the normal at-temperature calibrated instruments were accurate at the intermediate system temperature. When a test device failed following installation on the second pressure channel, the auto initiate low pressure SI logic was made-up and a SI initiated. The injection caused all injection pumps to start, letdown and charging were isolated, and a rapid filling of the pressurizer occurred challenging administrative pressurizer level limits established to assure integrity of the RCS at lower temperatures.

Entergy procedure EN-WM-104, Step 5.2(a), requires that a risk assessment be performed when any safety-related component is taken out of service for planned activities. Further, EN-WM-104, Attachment 9.2, Qualitative Risk Assessment; specifies for conditions that could cause a SI actuation or could result in a technical specification active shutdown LCO; or a loss of redundancy; that integrated risk be declared high. If the percentage of LCO time to be used is greater than 75 percent, or there was a high probability of a transient initiator, then Orange risk is assigned. Indian Point procedure IP-SMM-WM-101, On-Line Risk Assessment, Step 4.1.10, required that planned removal of technical specification equipment for more than half of the allowable outage time shall be reviewed by the operations manager prior to execution, and approved by the plant manager. The procedure states that planned removal from service of any components that cause a resulting risk color of Orange are to be reviewed by the operations manager, approved by the plant manager, and shall have a contingency plan.

Because the operators did not determine the technical specification requirements affected by the test, the test was excluded from the risk assessment, and the expected Orange risk actions were not taken.

Entergy entered the event into their CAP as CR-IP3-2013-2115. A root cause evaluation was initiated to determine the acceptability of conducting this test with the plant at low pressure in Mode 3 and address extent of condition. The inspectors conducted a review of the event including interviewing involved personnel and checking procedures.

Analysis:

The inspectors determined that the failure to accurately assess the risk impact of performing reactor protection logic testing at pressures below normal operating conditions, including not identifying the appropriate technical specification allowed outage times for the engineered safety features actuation interlocks, and evaluating the effects of the testing on PORV operation, was a performance deficiency that was reasonably within Entergys ability to foresee and correct and should have been prevented. The finding was more than minor because it was associated with the configuration control attribute of the Mitigating Systems cornerstone and affected the cornerstone objective of ensuring the availability of systems that respond to initiating events to prevent undesirable consequences. In addition, in accordance with IMC 0612, Appendix E, Example 7.f, had the risk assessment for the testing been done correctly, the assessment would have determined the impairment of the low pressure ESFAS interlocks and would have placed the plant in an administrative higher risk condition (Orange). In the orange condition, risk management actions such as a critical evolutions meeting and other reviews would have been required. The finding was evaluated using IMC 0609, Appendix K, Maintenance Risk Assessment and Risk Management Significance Determination Process, and determined to be of very low safety significance (Green) because the actual incremental core damage frequency deficit was determined to be very small, less than 1E-6. Key risk factors included an exposure time of less than two hours and the continued power operated relief valve manual operation capability. The inspectors determined this finding had a cross-cutting aspect in Human Performance, Work Control, when Entergy personnel did not take risk insights, job site conditions such as the plant pressure, technical specification requirements, and pressurizer level indication into consideration along with the need for contingencies when preparing for testing H.3(a).

Enforcement:

10 CFR 50.65(a)(4) requires, in part, that before performing maintenance activities, including surveillance testing, the licensee shall assess and manage the increase in risk that may result from the proposed activities. Entergy implements these requirements using their procedure EN-WM-104, On-Line Risk Assessment, which requires a critical evolution meeting and other risk management actions when an integrated risk color of Orange or higher results from a risk assessment. Contrary to the above, on March 27, prior to performing monthly surveillance test, 3-PT-M13B, Reactor Protection Logic Channel Functional Test, plant personnel ran a computer based risk assessment of the test and determined a risk color Orange, but disputed the result and did not manage the administratively required risk such as by having a critical evolution meeting as specified by their procedure. As a result, when the test was conducted, an inadvertent SI was actuated. Following the SI, operators stabilized the plant, documented the event in their CAP as CR-IP3-2013-2115, and initiated a review of activities including a root cause evaluation. Licensee Event Report (LER)

===05000286/2013-005-00 was issued regarding this event. Because this issue is of very low safety significance (Green) and Entergy entered it into their CAP (CR-IP3-2013-2115), this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy. (NCV 05000286/2013003-01, Failure to Assess and Manage Risk Associated with Reactor Testing Below Normal Operating Conditions)

.2 Annual Sample: Unit 3 Pressurizer Safety Valve, RC-PCV-468, Failed Its Setpoint Test

CR-IP3-2012-1403===

a. Inspection Scope

The inspectors performed an in-depth review of Entergys evaluation and corrective actions associated with the setpoint failure of PSV RC-PCV-468, to determine whether Entergy personnel were appropriately identifying, characterizing, and correcting problems associated with this issue, the inspectors assessed Entergys problem identification threshold; apparent cause analysis of the event; extent of condition reviews; reportability determination, and the prioritization, timeliness, and adequacy of corrective actions.

The inspectors reviewed Entergys cause evaluation and associated documentation for the event, interviewed engineering personnel, conducted a review of previous similar events to ensure appropriate characterization, and reviewed Entergys corrective action process implementation and close out documentation for the issue.

b. Findings

Introduction:

The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, when Entergy failed to identify and correct a condition adverse to quality associated with the Unit 3 PSVs. Specifically, in 2005 and in 2008, safety valves were found to have lifted outside of the technical specification acceptance band; however no investigation was done to determine the cause. As a result, in 2011, a PSV (PCV-468) lifted at higher than its setpoint pressure. Entergy initiated a cause determination and determined the problem was due to spring fatigue. A corrective action to include spring rate testing in the scope of the inspection was specified for future outages.

Description:

On June 28, 2012, Entergy submitted LER 50-286/2012-003-00, Technical Specification Prohibited Condition Due to a Pressurizer Safety Valve Discovered Outside Its As-Found Lift Setpoint Test Acceptance Criteria. During Refueling Outage 3R16, the three PSVs were removed from Unit 3 and tested at an offsite facility. On May 1, 2012, the vendor reported that one of the three valves (RC-PCV-468) lifted at 2617 psig, outside of its as-found lift setpoint test acceptance criteria (2485 psig +/-3 percent).

Entergy entered this issue in their CAP as CR-IP3-2012-1403 and initiated an apparent cause investigation.

On October 24, 2012, the vendor performed failure analysis of the spring assembly in accordance with the applicable manufacturers (6x6 Crosby Model: HB-BP-86-E) spring datasheet and determined that the tested K-rate of the spring assembly was below the acceptance range for that particular spring. The vendor concluded that if the K-rate is low, the spring would require additional compression to obtain the desired 2485 psig set pressure. In adding this extra spring compression, it is possible for the spring-rate to become non-linear over time and the initial actuation could be high. Once the spring deflects during the initial lift, the following actuations would be lower, as in the case of PCV-468. Entergy determined that the apparent cause of this failure was lack of a replacement preventive maintenance task for the safety valves.

The inspectors reviewed the history of previous failures and determined that there were five lifts outside of the setpoint tolerance at Indian Point Unit 3 from 2000-2012. In these earlier cases, Entergy did not identify the cause of the failure. In 2000, all three of the PSVs failed the lift setpoint acceptance criteria, and a licensee-identified violation was cited by the NRC. In 2005, PSV-464 was removed during 3R13, and the as-found pressure was (2578) 3.7 percent above the acceptance pressure of 2485 psig +/-3 percent. Even though the PSV was removed in 2005, CR-IP3-2007-00679 was not generated until 2007, prior to installation of the valve during 3R14. The condition report was closed with the explanation that there was no operability concern as the currently installed PSVs were pretested. The condition report did not identify the cause of the failure nor did it specify corrective actions. In 2008, PSV-464 (Tag no RC-PCV-468),removed during 3R14, lifted at 2403 psig (-3.4 percent), below the 2485 psig +/-3 percent acceptance range. CR-IP3-2008-768 was generated to document the condition; however, no further investigation was performed.

The inspectors reviewed the operability determination for the installed safety valves in 2005 and 2008 and determined that Entergy did not account for the potential of the valve setpoint to drift during the operating cycle. NRC Information Notice 2006-24, Recent Operating Experience Associated with Pressure and Main Steam Safety/Relief Valve Lift Setpoints, states that, Setpoint drift is the result of many random variables and is usually considered a function of time since calibration and setting. The inspectors concluded that regardless of operating experience and previous failures of Unit 3 PSVs, Entergy did not perform adequate evaluations following problems in 2005 and 2008 to determine the cause of the setpoint drift.

On October 29, 2012, Entergy initiated a corrective action to revise the current and future Indian Point PSVs purchase orders to include spring rate testing in the scope of work.

Analysis:

The inspectors determined that the failure to take timely corrective action to correct a condition adverse to quality, regarding setpoint drift for Unit 3 PSVs in 2005 and 2008, was a performance deficiency that was within Entergys ability to foresee and correct and should have been prevented. Specifically, Entergy failed to resolve a potentially degraded condition associated with the setpoint drift for installed PSVs. The finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences when the test failure recurred in 2011. In accordance with IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, the finding screened to be of very low safety significance (Green), when all screening questions were answered no. The inspectors noted that the redundant valves remained capable of maintaining plant pressure below the safety limit of 2735 psi in all cases and there was no actual loss of function.

Because Entergy completed lift testing of all safety valves prior to installation in the plant, there was no immediate safety concern. The inspectors determined that no cross cutting aspect was applicable to this performance deficiency because it was not reflective of current licensee performance.

Enforcement:

10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires, in part, that measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and non-conformances are promptly identified and corrected. Contrary to the above, following safety valve lift setpoint failures in 2005 and 2008, Entergy did not promptly identify and correct a deficiency associated with spring relaxation in Unit 3 PSVs. Specifically, following the 2005 and 2008 setpoint failures for PSVs, up to and including a failure of RC-PCV-468 during testing in 2012, Entergy did not identify and correct the cause of the failures, i.e. spring assembly fatigue. Because this violation is of very low safety significance (Green) and has been entered into Entergys CAP (CR-IP3-2013-2236), it is being treated as an NCV consistent with Section 2.3.2 of the NRC Enforcement Policy.

.3 Annual Sample:

Water Intrusion into 480VAC Bus Ducts (1 sample)

a. Inspection Scope

The inspectors performed an in-depth review of Entergy's evaluations and corrective actions associated with condition report CR-IP2-2013-01748, for water intrusion into the EDG 480VAC bus ducts. Specifically, a small roof leak in the underground electrical cable tunnel resulted in water dripping into the 480VAC bus ducts during occasional periods of heavy rain.

The inspectors assessed Entergy's problem identification threshold, problem analysis, extent of condition reviews, compensatory actions, and the prioritization and timeliness of Entergy's 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 50, Appendix B. The inspectors performed field walkdowns and interviewed engineering personnel to assess the reasonableness of the planned corrective actions and to evaluate the extent of any on-going bus duct degradation problems. The inspectors observed portions of Entergy's visual inspections and reviewed recent insulation and bus bar connection inspection results. In addition, the inspectors reviewed Entergy's bus duct preventive maintenance program, routine bus duct inspection and testing, selected bus duct test results, and bus duct inspection schedules.

b. Findings

No findings were identified.

On May 8, 2013, during a routine walkdown in the electrical cable tunnel, the inspectors identified a roof leak dripping water into an EDG bus duct. The inspectors concluded that Entergy staff were also aware of the leak because plastic sheeting had been recently taped in-place to provide temporary protection to other cables and conduit in the area of the leak. In response to the inspector's observations, Entergy initiated condition report CR-IP2-2013-01748, performed detailed visual inspections and an engineering assessment to evaluate the impact of the water intrusion, and scheduled repairs to stop the leak.

Entergy's technical review determined that, although the installed bus ducts were rated for indoor conditions, they were suitable for use in either dry or occasionally wet environmental conditions. Entergy's determination was based on a comparison of the design characteristics for indoor and outdoor bus ducts. Both indoor and outdoor ducts were ventilated (e.g., louvered openings top and bottom) and used the same insulated bus bars, insulation, and splice configurations. The primary difference between indoor and outdoor ducts was that for indoor applications, the bus duct housing was bonderized enameled steel, while outdoor applications used galvanized painted steel housing. In addition, Entergy's visual inspections on the interior and exterior of the bus ducts at the wetted locations showed only minor surface corrosion of the bus duct housing, with no pitting or flaking, and no degradation on the bus bar surfaces, insulation, or splice connections. Therefore, Entergy concluded that occasional wetting of the ducts was within the design characteristics of the installed indoor ducts. Although the inspectors noted that the vendor specifications for indoor bus ducts did not specifically discuss environmental conditions, such as occasional wetting, the inspectors concluded that Entergy's assessments were reasonable, based on visual inspections, recent test results, and comparison of design characteristics.

The inspectors identified a weakness in the implementation of Entergy's CAP.

Specifically, Entergy personnel were aware of the leak but had not initiated a condition report. In addition, the last two maintenance rule structural monitoring inspections, performed in 2004 and 2008, also identified roof leaks, but condition reports were not initiated. The electrical tunnel was an underground safety-related structure, and the leak was located at a seismic joint approximately 12 feet below grade. Based on interviews with Entergy's staff, the inspectors determined that the tunnel's design drawings and specifications showed the seismic joint to be sealed with an elastomer material, and did not specify any allowable leakage or leakage limits. Therefore, the inspectors concluded that the joint sealant had sufficiently degraded to allow ground water leakage through the tunnel roof, and therefore constituted a non-conforming condition to the tunnel's structural design specifications (e.g., a condition adverse to quality). The inspectors determined that not identifying a condition adverse to quality was a violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action.

The inspectors also identified a weakness in the implementation of Entergy's corrective actions. Specifically, the small roof leak had existed in the electrical tunnel since 1999.

During that 14 year period, eight condition reports, five of which were NRC identified, had been initiated and subsequently closed out, but no physical work to repair or mitigate the leak had been planned, scheduled, or performed. The inspectors determined that not correcting a condition adverse to quality during a 14-year period was a violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action.

The inspectors determined that these issues were minor because the actual impact of the water intrusion was determined to not adversely affect the bus ducts ability to perform its design function. Entergy entered these issues into their CAP as CR-IP2-2013-02913.

.4 Semi-Annual Trend Review (1 sample)

a. Inspection Scope

The inspectors performed a semi-annual review of Indian Point 2 and 3 issues, as required by Inspection Procedure 71152, Problem Identification and Resolution, to identify trends that might indicate the existence of more significant safety issues. The inspectors considered repetitive or closely-related issues that may have been documented by Entergy outside of the corrective action program, such as in the Entergy First Quarter 2013 Trend Report dated May 13, 2013, the Top Ten Equipment Problems list, system health reports, and maintenance or CAP backlogs. The inspectors reviewed the IPEC Management Review Meeting package dated May 9, 2013, and selected Plant Health Committee meeting packages for trends not identified in the CAP. The inspectors also reviewed Entergys CAP database for the first and second quarters of 2013 to assess condition reports written in various subject areas (equipment problems, human performance issues, etc.), as well as individual issues identified during the daily condition report review (Section 4OA2.1), to verify that Entergy personnel were appropriately evaluating, trending, and reporting adverse conditions in accordance with applicable procedures.

b. Findings and Observations

No findings were identified.

No trends were identified that indicated a potentially safety significant issue. Entergy actively identified trends and addressed the trends within the CAP. The inspectors evaluated a sampling of problem reports used by Entergy in their first quarter 2013 trend report and screened problem reports from the second quarter to determine whether issues were appropriately considered as emerging or adverse trends. For identified problems, the inspectors verified that the issues were addressed within the CAP at the appropriate significance level. Examples of trends being monitored by Entergy included procedure use and adherence in maintenance, housekeeping, and problems with document control. A monitored trend associated with problems with static inverters was being addressed in the Entergy maintenance rule program. For these licensee-identified trends, the inspectors verified that Entergy had established actions to mitigate the problems and prevent recurrence.

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 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 Entergys follow-up actions related to the events to assure that Entergy implemented appropriate corrective actions commensurate with their safety significance.

Unit 3

March 27, 2013; automatic actuation of SI and engineered safety features during reactor protection system functional testing

b. Findings

Introduction:

The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion V, Procedures, when Entergy did not maintain appropriate written procedures for responding to an inadvertent SI on Unit 3 when below the normal operating conditions RCS temperature.

Description:

On March 27, 2013, during performance of a surveillance test, a malfunctioning instrument test signal lead caused an inadvertent SI actuation. The reactor was not operating at the time of the event. A plant heatup was in progress in accordance with Procedure 3-POP-1.1, Plant Heatup from Cold Shutdown Condition, with reactor coolant temperature at approximately 389°F.

When the SI actuated, operators appropriately entered 3-E-0, Reactor Trip or Safety Injection, but were immediately challenged by conflicts between guidance in the heatup procedure and guidance in the emergency operating procedure. The heatup procedure, 3-POP-1.1, directed operators in event of a SI, to determine the SI was invalid in the sense that actual initiation conditions were not met; then stop all high head SI pumps and enter emergency operating procedures. Emergency Procedure 3-E-0, contrary to 3-POP-1.1, provided the Westinghouse Owners Group response strategy of:

1) determining all coolant injection functioned as designed, 2) formally evaluating numerous criteria to determine whether an accident (loss of coolant, steam line break, steam generator tube rupture) was in progress and then, 3) with RCS pressure greater than 1700 psi and stable or rising, transition to emergency procedure ES-1.1, Safety Injection Termination.

Indian Point Unit 3 uses administrative controls to prevent over-pressurization of the RCS when temperature is between 330°F and 380°F. The basis for low temperature over-pressure (LTOP) Technical Specification 3.4.12 states that administrative controls in the Technical Requirements Manual are used to limit the potential for exceeding fracture toughness (10 CFR 50, Appendix G) limits when greater than the LTOP arming temperature (i.e., >330°F) but below the minimum temperature at which the RCS safety valves can provide overpressure protection. The technical specification basis further states these controls may include operating with a bubble in the pressurizer and/or otherwise limiting activities when reactor coolant temperature is in the specified range (between 330°F and 380°F).

Operators appropriately entered the emergency operating procedures following the SI actuation, rather than first performing the event diagnostic and response actions directed by the plant operating procedure. However, based on knowledge and training, the operators recognized that the heatup procedure directed specific actions to stop SI pumps on an invalid actuation in the brittle fracture region of plant operation. This operational area, defined at temperatures <380°F, was administratively controlled by the heatup procedure as <400°F RCS temperature. Emergency Operating Procedure Users Guide Step 4.4.18 allowed for parallel usage of sub-tier procedures such as plant operating procedures, but only if they did not interfere with the actions called for in the emergency procedures.

Two senior reactor operators conferred with the operations manager and agreed that it was appropriate and necessary to stop high head SI pumps prior to filling the pressurizer to preclude filling the RCS solid and challenging vessel pressure / temperature limits.

Six minutes into the event, after confirming the signal was invalid, and immediately prior to Step 11 of 3-E-0 which would start a high pressure charging pump, the crew stopped all high head SI pumps. Then, in Step 18 of 3-E-0, which determined if SI flow should be terminated, the crew took exception to the procedure requirement for RCS pressure greater than 1700 psig and proceeded to 3-ES-1.1, Safety Injection Termination, even though RCS pressure was being maintained less than 1700 psig. The conflicting procedural guidance contributed to the operators taking action in conflict with the controlling procedure, 3-E-0, to address what they perceived to be a challenge to pressure limits. The operators were not aware that at the existing RCS temperature, which remained above 380°F throughout the event, vessel integrity was not a concern and 3-E-0 could have been implemented as designed without exceeding fracture toughness limits. Entergy personnel documented the March 27 event in the CAP as CR-IP3-2013-2115 and initiated a root cause evaluation. The inspectors interviewed operations personnel involved in the event, engineering personnel knowledgeable in fracture toughness limitations at Indian Point, and operations training personnel.

Operator understanding of, and training on, the Unit 3 Combined Heatup / Overpressure Protection System Curve (3-Graph-RCS-1F) further contributed to the control room operators sense of urgency for stopping SI. Through interviews, inspectors determined that operators understood the upper pressure / temperature limit on this curve to relate to Appendix G brittle fracture limits. The operators did not appear to understand that the limits above 380°F were based on different considerations than those shown for temperature below 380°F. Reviews of documents after the event revealed problems and inconsistencies with procedural guidance on RCS pressure / temperature limits. Unit 3 Technical Requirements Manual TRO 3.4.A established pressurizer level controls when between 330°F and 411°F for brittle fracture protection, although the upper limit was actually 380°F. The combined pressure temperature graph (3-Graph-RCS-1F) showed a steam generator tube sheet differential pressure limit of 1550 psid, when the supporting analysis shows the limit was 1700 psid.

Analysis:

The inspectors determined that the failure to maintain appropriate written procedures for responding to a SI system actuation when in MODE 3 at low RCS temperature was a performance deficiency that was reasonably within Entergys ability to foresee and correct and should have been prevented. This finding was more than minor because, if left uncorrected, the procedure deficiencies have the potential to lead to a more significant safety concern related to exceeding vessel integrity pressure limitations if a charging pump was started in solid conditions below 380°F. In accordance with IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, the finding screened to be of very low safety significance (Green), when all screening questions were answered no. The finding was assigned a cross-cutting aspect in the area of Human Performance, Resources, because Entergy staff did not ensure that design documentation and procedures were adequate to assure nuclear safety. H.2(c)

Enforcement:

10 CFR 50, Appendix B, Criterion V, states, in part, that activities affecting quality shall be prescribed by documented procedures of a type appropriate to the circumstances and shall be accomplished in accordance with these procedures, and the procedures shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Entergy accomplishes this requirement using procedures that include emergency procedure 3-E-0, Reactor Trip or Safety Injection; operating procedure 3-POP-1.1, Plant Heatup from Cold Shutdown; the Unit 3 Technical Requirements Manual; and 3-GRAPH-RCS-1F, Unit 3 Combined Heatup / Overpressure Protection System Curve. Contrary to the above, as of March 27, Entergy failed to maintain prescribed procedures appropriate to the circumstances for managing overpressure protection at low temperatures in operating Mode 3. Specifically, at temperatures below 380°F, emergency operating procedure 3-E-0 required actions that could challenge overpressure protection when a charging pump was started with all SI pumps running, 3-POP-1.1 directed placing all SI pumps in trip pull out at temperatures higher than required for overpressure protection, and both the Technical Requirements manual and 3-GRAPH-RCS-1F inappropriately limited the operators use of safety systems at temperatures greater than 380°F in conflict with emergency procedure requirements. Because this violation was of very low safety significance (Green) and has been entered into Entergys CAP (CR-IP3-2013-2115), this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy.

.2 (Closed) LER 05000286/2012-003-00 and LER 05000286/2012-003-01: Technical

Specification Prohibited Condition Due to a Pressurizer Safety Valve Discovered Outside Its As-Found Lift Setpoint Test Acceptance Criteria

On May 1, 2012, Entergy engineering personnel were notified by Wyle laboratories that one of three PSVs (RC-PCV-468) was outside its as-found lift setpoint acceptance criterion (2411-2559 psig). The as-found set pressure testing acceptance criterion for operability is 2485 psig +/- 3 percent. The safety valve lifted at 2617 psig which is 5.3 percent above the 2485 psig set pressure. Technical Specification 3.4.10 (Pressurizer Safety Valves) requires three PSVs to be operable with lift settings set at greater than 2460 psig and less than 2510 psig, and Technical Specification 3.4.10, condition A (one PSV inoperable), requires in action a.1, to restore an inoperable valve to operable status in 15 minutes. Entergy staff entered this issue into their CAP as CR-IP3-2012-01403.

The corrective actions were to disassemble and inspect valve PC-PCV-468 to determine the cause of the failure and to develop an inspection and repair plan.

Subsequently, Entergy evaluated a potential contributing cause associated with the PSV to be spring fatigue and submitted supplemental LER (50-286/2012-003-001) to include information acquired through their evaluation, and captured in the CAP in CR-IP3-2012-01403. The corrective actions included replacement of the spring for RC-PCV-468 and inspection of the spring rate on the remainder of the two safety valves. Additionally, Entergy will revise the inspection and repair plan to include safety valve disassembly and complete spring assembly inspection that includes spring measurements, inspecting overall spring condition, and performing a spring-rate test every 10 years or when directed by engineering. The inspectors identified one violation during the review of this LER and the supplement which is documented in Section 4OA2 of this report. These LERs are closed.

.3 (Closed) Licensee Event Report (LER) 05000286/2013-005-00: Automatic Actuation of

Engineered Safety Features During Reactor Protection System Functional Testing

On March 27, 2013, while in Mode 3 during recovery from the Unit 3 refueling outage, an inadvertent SI occurred during reactor protection logic testing. The actuation was caused when a jumper installed in a pressurizer pressure channel failed due to an internal fault after the low pressure SI block feature had been disabled by the false high pressure signals installed for the test. NRC inspectors responded to the control room during the event and observed the operators activities. Plant operators responded to the SI using emergency operating procedures and stopped the actuation. A root cause was done following the event and a number of issues were identified. The inspectors reviewed the LER and verified that the defective test lead had been removed from service and that Entergy test procedure 3-PT-M13B, being performed when the actuation occurred, had been revised to prevent a recurrence. The inspectors identified two violations during the review of this LER, which are documented in Sections 1R13 and 4OA3 of this report. The LER is closed.

4OA6 Meetings, Including Exit

On July 17, 2013, the inspectors presented the inspection results to Mr. John Ventosa, Site Vice President, and other members of the Entergy staff. The inspectors verified that no proprietary information was retained by the inspectors or documented in this report.
