SUMMARY

IR 05000382/2016002; 04/01/2016

- 06/30/2016, Waterford Steam Electric Station, Unit 3; Maintenance Effectiveness, Maintenance Risk Assessments and Emergent Work Control, Maintenance of Emergency Preparedness, and Problem Identification and Resolution

. The inspection activities described in this report were performed between April 1 and June 30, 2016 , by the resident inspectors at Waterford Steam Electric Station and inspectors from the NRC's Region IV office and other NRC offices. Four findings of very low safety significance (Green) are documented in this report. All of these findings involved violations of NRC requirements

. The significance of inspection findings is indicated by their color (Green , White, Yellow, or Red), which is determined using Inspection Manual Chapter 0609, "Significance Determination Process." Their cross-cutting aspects are determined using Inspection Manual Chapter 0310, "Aspects within the Cross-Cutting Areas." Violations of NRC requirements are dispositioned in accordance with the NRC Enforcement Policy. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process."

Cornerstone: Mitigating Systems

Green.

The inspectors identified a non-cited violation of Technical Specification 6.8 , "Procedures and Programs," associated with the licensee's failure to properly pre-plan and perform maintenance on safety-related components in accordance with EN

-DC-335, "Preventative Maintenance Basis Template." Specifically, the licensee did not follow the required preventive maintenance basis template for the safety-related cable vault and switchgear ventilation system, and was performing vibration monitoring of these components on an 18

-month frequency instead of the required 3

-month frequency

. As a result, the licensee was deviating from the industry standard preventive maintenance recommendations without documented technical bases, and the required preventive maintenance tasks on these safety-related components were not performe d. The licensee entered this condition into their corrective action program as condition report CR

-WF3-2016-02353. The licensee restored compliance by assigning the proper preventive maintenance activ i t ies for the components in this system and instituting the appropriate frequency. In addition, a maintenance scope review is being performed

. The performance deficiency was more than minor because it affected the Equipment Performance attribute of the Mitigating Systems cornerstone and its objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences

. Specifically, actions to detect, preclude and address degradation of the safety-related components were delayed

. The inspectors screen ed the finding in accordance with NRC Inspection Manual Chapter (IMC) 0609, "Significance Determination Process

." Using IMC 0609, Appendix A, "The Significance Determination Process for Findings At-Power," the inspectors determined that the finding was of very low significance (Green) because all the screening questions in Exhibit 2

- "Mitigating Systems Screening Questions" were answered 'No'.

The finding had a n Identification cross-cutting aspect in the area of Problem Identification and Resolution because individuals did not identify issues completely, accurately, and in a timely manner in accordance with the corrective action program. Specifically, during previous vibration tests, the licensee had opportunities to identify the incorrect classification of the preventive maintenance task but did not do so [P.1]. (Section 1R12)

Green.

The inspectors identified a non-cited violation of 10 CFR 50.65, "Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," section (a)(4)because the licensee did not properly assess and manage risk associated with maintenance on the dry cooling tower fans train B. Specifically, the licensee failed to adequately assess risk and take appropriate risk management actions when replacing a logic card associated with the dry cooling tower train B fans. As a result, an electrical transient occurred that caused unexpected valve movements in component cooling water and auxiliar y component cooling water train B systems, an unexpected start of the auxiliary component cooling water pump train B, and the unexpected shutdown of essential chiller train AB. The licensee entered this issue into their corrective action program as condition report C R-WF3-2016-04084. Corrective actions included reassessing the risk associated with the maintenance and identifying appropriate risk management actions to use when performing similar maintenance activities in the future

. The inspectors determined that the performance deficiency was more than minor because it was associated with the Configuration Control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences

. Specifically, the failure to take appropriate risk management actions resulted in unexpected valve movements, an unexpected start of auxiliary component cooling water pump B, and an unplanned entry in to Technical Specification 3.7.4, "Ultimate Heat Sink." The inspectors used Inspection Manual Chapter 0609, Appendix K, "Maintenance Risk Assessment and Risk Management Significance Determinatio n Process," dated May 19, 2005, Flowchart 2, "Assessment RMAs," and determined the need to calculate the incremental core damage probability to determine the significance of this issue. The Waterford probabilistic risk assessment model yielded an incremental core damage probability, or actual increase in risk during this work window, of 1.5x10

-8. In accordance with Flowchart 2 in Appendix K, because the incremental core damage probability was less than 1x10

-6, the finding screened as having very low safety significance (Green). This finding had a Procedure Adherence cross-cutting aspect in the area of Human Performance because individuals did not follow processes, procedures and work instructions

. Specifically, the licensee did not assess and manage the risk associated with the maintenance in accordance with EN

-WM-104 , "On Line Risk Assessment"

[H.8]. (Section 1R13)

Green.

A self-revealing, Green, non-cited violation of Technical Specification 6.8 , "Procedures and Programs," occurred because the licensee did not establish adequate procedures for the operation of the emergency diesel generators

. Specifically, prior to July 7, 2015, the licensee's procedure for operating the emergency diesel generator s allowed lube oil pressur e to be maintained low enough to activate a design feature of the starting air system that injects starting air into the diesel cylinders, which could damage the emergency diesel generator turbocharger

. The licensee entered this issue into thei r corrective action program as condition report CR-WF3-201 5-04459. The corrective action taken to restore compliance was to increase the procedure requirement for operating lube oil pressure from 35 psig to 45 psig.

The inspectors concluded that the performance deficiency 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

. Specifically, the procedural allowance to run the emergency diesel generator lube oil pressure at the starting air injection setpoint could have resulted in the failure of the emergency diesel generator s when they were called upon to perform their safety function

. The inspectors used NRC Inspection Manual Chapter 0609

, Appendix A, "The Significance Determination Process for Findings At-Power," to determine the significance of the finding

. T he inspectors determined that the finding required a detailed risk evaluation because it represented the loss of a system or function

. The detailed risk evaluation determined that the finding is of very low safety significance (Green)

. The senior reactor analyst estimated the increase in core damage frequency to be 4.6E

-7/year and the increase in large early release frequency to be 3.9E

-8/year. Dominant core damage sequences were medium break losses of coolant accidents and steam generator tube ruptures with associated losses of off-site power

. Core damage was mitigated by the remaining emergency diesel generator.

This finding had an Evaluation cross-cutting aspect in the area Problem Identification and Resolution, because the licensee did not thoroughly evaluate issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance

. Specifically, the licensee's previous evaluation performed for operating the emergency diesel generators with low lube oil pressures did not thoroughly evaluate the risk associated with the starting air system [P.2]. (Section 4OA2)

Cornerstone: Emergency Preparedness

Green.

The inspectors identified a non-cited violation of 10 CFR 50.54(q)(2), which requires a power reactor licensee to follow and maintain the effectiveness of the site emergency plan

. Specifically, Waterford Steam Electric Station, Unit 3, failed to conduct two proficiency drills in calendar year 2015 as required by the Site Emergency Plan, Revision 46, Section 8.1.2.4. The licensee has initiated work tracker surveillances to ensure all drills required in 2016 are performed. The issue is more than minor because the finding was associated with the Emergency Response Organization Performance attribute and adversely affected the Emergency Preparedness cornerstone objective to ensure the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency

. The finding was evaluated using Inspection Manual Chapter 0609, Appendix B, "Emergency Preparedness Significance Determination Process," dated September 23, 2014, and was determined to be of very low safety significance (Green) because it was a failure to comply with NRC requirements , was no t a risk-significant planning standard function, and was not a lost or degraded planning standard function

. The inspector s determined that the finding had a Work Management cross-cutting aspect in the area of Human Performance, because the emergency preparedness department did not properly schedule, oversee, and manage required activities

[H.5]. (Section 1EP5)

PLANT STATUS

The Waterford Seam Electric Station, Unit 3, began the inspection period at 100 percent power and maintained 100 percent power for the duration of the inspection period.

. In addition, the inspectors verified that industry operating experience had been taken into account where practicable and the licensee made appropriate adjustments as a result of the periodic evaluation.

These activities constitute d completion of two maintenance effectiveness samples , a s defined in Inspection Procedure 71111.12.

b. Findings

Introduction

. The inspectors identified a Green, non

-cited violation of Technical Specification 6.8, "Procedures and Programs," associated with the licensee's failure to properly pre

-plan and perform maintenance on safety-related components in accordance with EN-DC-335, "Preventative Maintenance Basis Template."

Description

. On April 14, 2016, licensee maintenance personnel took vibration data on the cable vault and switchgear area ventilation air handling unit, AH

-25. The purpose of the cable vault and switchgear area ventilation system is to maintain a suitable operating environment for safety-related electrical equipment, battery, and cable areas during normal plant operations and accident conditions

. The vibration measurements were taken as part of a preventive maintenance task

. When operations personnel reviewed the data, they determined that the air handling unit's vibrations, which read 0.56 inches per second (ips)had exceeded the predictive maintenance program alert and alarm limits of 0.32 ips and 0.4 ips

. Due to the increased vibrations the site performed an operability evaluation and replaced the air handling unit's outboard bearings to address the vibrations

. During a review of the maintenance program for the cable vault and switchgear area ventilation system, the inspectors noted that AH-25 was classified as a high critical component. Per the licensee's preventive maintenance template, vibration data should have been taken every 3 months

. However, the task to take vibration data was assigned a test frequency for a non

-critical component

. The inspectors identified that even though AH-25 was classified appropriately, the preventive maintenance tasks associated with that component had not been identified as suc h. As a result, the licensee was taking AH-25 vibration data every 18 months

. The vibrations exceeded the predictive maintenance alert and action limits, but the fan was not submitted to increased

-frequency testing and monitoring that otherwise would have occurred if the vibration data was taken every 3 months. Further, the inspectors identified that in January 2015, during the prior 18

-month preventive maintenance task, vibration measurements were also higher than expected

, however, the licensee did not document the issue in a condition report.

In their review of the issue, the licensee found that as part of a maintenance optimization program in 2008, they had changed the classification of the cable vault and switchgear area ventilation system from non

-critical to critical

. However, the maintenance tasks associated with these components were not updated to match the new classification

. Consequently, the licensee was deviating from established industry recommendations without documented technical bases

. The inspectors noted this practice was not in accordance with site procedure EN-DC-335, "PM Basis Template

."

When the licensee performed an extent of condition review, 15 other components in the cable vault and switchgear ventilation system were identified as having a high critical classification

. In addition to other air handling units, the list included breakers and motors in that system

. However, those components' tasks also were also given maintenance frequencies associated with non

-critical components

. Following this discovery, the licensee is performing a maintenance scope review since the preventative maintenance basis template for these 16 components, might require additional preventive maintenance tasks after they are properly classified

. For example, for air handling equipment, in addition to the vibration monitoring task, the preventative maintenance basis template requires filter clean and inspection, external visual inspection, performance monitoring, and system functional tests that might not have been performed at the right frequency or at all

.

Analysis.

The failure to pre-plan and perform preventative maintenance on safety-related components in accordance with EN

-DC-335, "Preventative Maintenance Basi s Template ," was a performance deficiency which was reasonably within the licensee's ability to foresee and correct

. The performance deficiency was more than minor, and therefore is a finding, because it affects the Equipment Performance attribute of the Mitigating Systems cornerstone and its objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences

. Specifically, by incorrectly assigning the preventive maintenance code to maintenance tasks, the licensee did not perform the specifi ed preventive maintenance and tests at the frequency required by the licensee's preventive maintenance process

. As a result, actions to detect, preclude and address degradation of the safe ty-related components were delayed

. The inspectors screen ed the finding in accordance with NRC Inspection Manual Chapter (IMC) 0609, "Significance Determination Process

." Using IMC 0609, Appendix A, "The Significance Determination Process for Findings At

-Power," Exhibit 2

- "Mitigating Systems Screening Questions," the inspectors determined that the finding was of very low significance (Green) because it did not affect the design or qualification of a mitigating structure, system and component (and the structure, system and component maintained its operability), it did not represent a loss of safety function, it did not represent an actual loss of function of at least a single train for greater than its Technical Specification outage time, and it did not represent an actual loss of function of one or more non

-Technical Specification trains of equipment designated as high safety significant in accordance with the licensee's maintenance rule program for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The finding had an Identification cross-cutting aspect in the area Problem Identification and Resolution because individuals did not identify issues completely, accurately, and in a timely manner in accordance with the corrective action program. Specifically, during previous vibration tests, the licensee had opportunities to identify the incorrect classification of the preventive maintenance task but did not do so [P.1]. Enforcement

. Technical Specification 6.8, "Procedures and Programs," Section 1.a, requires, in part, that procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2

. Appendix A to Regulatory Guide 1.33, Section 9.a, requires, in part, that "maintenance that can affect the performance of safety

-related equipment be properly pre

-planned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances." The licensee established procedure EN

-DC-335, "PM Basis Template," Revision 6, to satisfy this requirement

. EN-DC-335 , Step 5.2.6 states that Fleet Preventative Maintenance Basis Templates can deviate from established EPRl or Industry Standard Preventive Maintenance recommendations provided the technical bases for the differences are documented within the preventative maintenance template. Contrary to the above, prior to April 13, 2016, the licensee deviated from established EPRl preventive maintenance recommendations and did not provide, nor document within the preventative maintenance template, the technical bases for the differences

. Specifically, the licensee did not follow the required preventive maintenance template for the safety

-related cable vault and switchgear ventilation system, and was performing vibration monitoring of these components on an 18

-month frequency instead of the required 3

-month frequency

. As a result, actions to detect, preclude and address degradation of the fan and other system components were delayed

. The licensee entered this condition into their corrective action program as condition report CR

-WF3-2016-02353. The licensee restored compliance by properly classifying the preventive maintenance activ i t ies for the components in this system and instituting the proper frequency. In addition, the licensee will perform a maintenance scope review

. Because this violation was of very low safety significance and the licensee entered the issue into their corrective action program, this violation is treated as a non

-cited violation, consistent with Section 2.3.2 of the Enforcement Policy: NCV 05000382/2016002

-01 , "Failure to Properly Pre

-Plan and Perform Maintenance on the Cable Vault and Switchgear Ventilation System." 1 R 13 Maintenance Risk Assessments and Emergent Work Control (71111.13)

a. Inspection Scope

The inspectors reviewed two risk assessments performed by the licensee prior to changes in plant configuration and the risk management actions taken by the licensee in response to elevated risk:

On April 18, 2016, planned yellow risk due to emergency diesel generator test and circulating water system maintenance On June 1, 2016, planned yellow risk due to work in the switchyard The inspectors verified that these risk assessment s were performed timely and in accordance with the requirements of 10 CFR 50.65 (the Maintenance Rule) and plant procedures

. The inspectors reviewed the accuracy and completeness of the licensee's risk assessments and verified that the licensee implemented appropriate risk management actions based on the result of the assessments.

The inspectors also observed portions of four emergent work activities that had the potential to cause an initiating event or to affect the functional capability of mitigating systems: On April 18, 2016, emergent replacement of dry cooling tower logic cards On May 16, 2016, emergent yellow risk due to inoperability of battery bank 3B

-S On June 3, 2016, emergent work on heater drain pump B On June 23, 2016, emergent work on main feedwater regulating valve #2 The inspectors verified that the licensee appropriately developed and followed a work plan for these activities

. The inspectors verified that the licensee took precautions to minimize the impact of the work activities on unaffected structures, systems, and components

. These activities constitute d completion of six maintenance risk assessments and emergent work control inspection samples , as defined in Inspection Procedure 71111.13.

b. Findings

Introduction

. The inspectors identified a Green, non

-cited violation of 10 CFR 50.65, "Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," section (a)(4)because the licensee did not properly assess and manage risk associated with maintenance on dry cooling tower train B fans. Specifically, the licensee failed to adequately assess risk and take appropriate risk management actions when replacing a logic card associated with dry cooling tower train B fans

. As a result, an electrical transient occurred that caused unexpected valve movements in component cooling water and auxiliary component cooling water train B systems, an unexpected start of auxiliary component cooling water pump train B, and the unexpected shutdown of essential chiller AB.

Description

. On March 22, 2016, the licensee replaced a logic card associated with the dry cooling tower train B fans

. The card is electrically daisy

-chained with two other logic cards and together provide controls for component cooling water and auxiliary component cooling water flow to essential chiller train B. While inserting the card, an electrical transient occurred resulting in spurious actuation of the card and the associated daisy

-chained cards

. The actuations resulted in unexpected valve movements in component cooling water and auxiliary component cooling water train B systems, an unexpected start of auxiliary component cooling water pump train B, and the unexpected shutdown of essential chiller AB

, which was aligned to train B at the time. The licensee previously entered Technical Specification 3.7.3, "Component Cooling Water and Auxiliary Component Cooling Water Systems" for separate maintenance and remained in the applicable technical specifications until the affected equipment was restored to service

. The dry cooling tower fan logic card work alone would not have led the licensee to enter any technical specifications

. Prior to performing the work, the licensee performed a risk assessment and determined that the work was of normal risk and no additional risk management actions were needed.

The inspectors noted that licensee procedure EN

-WM-104, "On Line Risk Assessment," Revision 12, step 5.2[1](a) required that a risk assessment be performed when any system, structure, or component in its scope is taken out of service for planned or emergent maintenance activities

. Further, EN

-WM-104 provides a list of mitigating actions to consider for such elevated risk conditions

. The inspectors also noted that

.3 of EN

-WM-104 specifically directs the licensee to consider elevated risk when working on energized components that are electrically daisy

-chained. The inspectors determined that the licensee did not assess risk in accordance with EN

-WM-104 and did not apply appropriate risk mitigating actions for the dry cooling tower card maintenance

. The licensee subsequently re-assessed the risk associated with the replacement of daisy

-chained dry cooling tower logic cards and will categorize the work as high risk for future maintenance activities

. As a result, the licensee will take risk management actions for future dry cooling tower logic card maintenance to prevent impacts to the plant, including manually placing the associated component cooling wate r and auxiliary component cooling water valves in their expected position prior to the maintenance to prevent inadvertent configuration changes

. In addition, the licensee will enter Technical Specification 3.7.4, "Ultimate Heat Sink" for the work.

Analys is. The inspectors determined that the licensee's failure to properly assess and manage risk associated with maintenance on logic cards associated with the dry cooling tower train B fans was a performance deficiency

. The inspectors determined that the performance deficiency was reasonably within the licensee's ability to foresee and correct. The performance deficiency was more than minor, and therefore a finding, because it was associated with the Configuration Control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences

. Specifically, the failure to take appropriate risk management actions resulted in unexpected valve movements, an unexpected start of the auxiliary component cooling water pump train B, and an unplanned entry in Technical Specification 3.7.4, "Ultimate Heat Sink."

The inspectors used Inspection Manual Chapt er 0609, Appendix K, "Maintenance Risk Assessment and Risk Management Significance Determination Process," dated May 19, 2005, Flowchart 2, "Assessment Risk Management Actions," and determined the need to calculate the incremental core damage probability (ICDP) to determine the significance of this issue

. As a bounding assumption, the senior reactor analyst assumed that the failure of train B equipment caused a complete failure of the entire train. The analyst also assumed, based on input from the inspectors, that all risk

-significant equipment was realigned and returned to a functional status within 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />

. With these assumptions, the Waterford probabilistic risk assessment model yielded an incremental core damage probability, or actual increase in risk during this work window, of 1.5x10-8. In accordance with Flowchart 2 in Appendix K, because the incremental core damage probability was less than 1x10

-6, the finding screened as having very low safety significance (Green).

This finding had a Procedure Adherence cross-cutting aspect in the area of Human Performance, because individuals did not follow processes, procedures and work instructions

. Specifically, the licensee did not assess and manage the risk associated with the maintenance in accordance with Procedure EN-WM-104 [H.8]. Enforcement

. Title 10 CFR 50.65, "Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," section a(4), states, in part, that before performing maintenance activities (including but not limited to surveillance, post

-maintenance testing, and corrective and preventive maintenance), the licensee shall assess and manage the increase in risk that may result from the proposed maintenance activities.

Contrary to the above, on March 22, 2016, the licensee failed to properly assess and manage the increase in risk that resulted from a proposed maintenance activity

. Specifically, the licensee failed to assess the risk and take appropriate risk management actions when replacing a logic card associated with the dry cooling tower train B fans

. As a result, an electrical transient associated with replacing the card caused unexpected valve movements in the component cooling water an d auxiliary component cooling water train B systems, an unexpected start of auxiliary component cooling water pump train B , and the unexpected shutdown of essential chiller AB.

The licensee entered this issue into their corrective action program as condition report CR-WF3-2016-04084. Corrective actions included reassessing the risk associated with the maintenance and identifying appropriate risk management actions to use when performing similar maintenance activities in the future

. Future risk management actions will be requiring operators to manual ly position valve that could be affected and entering Technical Specification 3.7.4

. Because the licensee has entered the issue into their corrective action program and the finding is of very low safety significance, this violation is being treated as a non

-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy:

NCV 05000382/2016002

b. Findings

Introduction

. The inspectors identified a Green non

-cited violation of 10 CFR 50.54(q)(2) for the licensee's failure to follow all the requirements of the site emergency plan in calendar year 2015

. Specifically, the licensee failed to conduct two proficiency drills during 2015 as required by the plan.

Description

. The inspector s reviewed drill and exercise evaluation reports for licensee drills conducted between January 1, 2015, and March 31, 2016. The inspector s compared the drills described in the evaluation reports with the requirements of the Waterford Steam Electric Station, Unit 3, Emergency Plan, Revision 46, Section 8.1.2.4, to verify that all drills required by the emergency plan had been completed

. The inspector s identified that no 2015 evaluation reports existed for an on

-site medical drill responding to a contaminated and injured worker or for a health physics drill

. The inspector s subsequently interviewed the emergency preparedness manager and emergency preparedness staff to determine whether the drills had been conducted.

The licensee stated that an on

-site medical drill was scheduled in September 2015; however, the drill was stopped before the participants could demonstrate the ability to stabilize the (simulated) patient and address their contaminati on. A second medical drill was scheduled for the fourth quarter 2015, but was not held because the refueling outage went longer than anticipated

. After the outage, personnel were not available, either as drill controllers or as participants

. A medical drill was subsequently held in January 2016, but did not meet the 2015 annual requirement

. Additionally, the licensee failed to identify that a health physics drill was not scheduled for calendar year 2015, and the licensee staff did not recognize that a drill was required

. Therefore, the inspector s concluded that the required drills had not been performed and the licensee had not followed the requirements of Emergency Plan, Revision 46, Section 8.1.2.4.

Analysis.

The failure to follow the requirements of the approved site emergency plan is a performance deficiency within the licensee's ability to foresee and correct

. The issue is more than minor because the finding adversely affected the Emergency Preparedness cornerstone objective and was associated with the Emergency Response Organization Performance attribute. The finding impacted the cornerstone objective because adequate measures to protect the health and safety of the public may not be taken if required on

-site proficiency drills are not performed

. The finding was evaluated using Inspection Manual Chapter 0609, Appendix B, "Emergency Preparedness Significance Determination Process," dated September 23, 2014. The finding was determined to be of very low safety significance (Green) because it was a failure to comply with NRC requirements of 10 CFR 50.54(q)(2), was not a risk-significant planning standard function, and was not a lost or degraded planning standard function

. The function was not lost because some of the required proficiency drills were performed

.

The inspector s determined that the finding had a Work Management cross

-cutting aspect in the area of Human Performance, because the emergency preparedness department did not properly schedule, oversee, and manage required activities

. The inspector s determined that the failure to conduct the required drills was also associated, in part, with the unavailability of staff during a plant outage that was unexpectedly extended [H.5].

Enforcement

. Title 10 of the Code of Federal Regulations 50.54(q)(2), states, in part, that a power reactor licensee shall follow and maintain in effect, an emergency plan that meets the requirements of Appendix E to Part 50 and the standards of 10 CFR 50.47(b). The Waterford Steam Electric Station, Unit 3 , Emergency Plan, Revision 46, Sections 8.1.2.4(4) and 8.1.2.4(6) requires that Waterford annually conduct a medical emergency drill and two semiannual health physics drills

. Contrary to the above, between January 1 and December 31, 2015, Waterford failed to follow an emergency plan meeting the requirements of Appendix E to Part 50, and the standards of 10 CFR 50.47(b). Specifically, the licensee failed to conduct a medical emergency drill and one semiannual health physics drill during calendar year 2015 as required by the Waterford Steam Electric Station, Unit 3, Emergency Plan, Revision 46. The licensee entered these issues into their corrective action program as condition reports CR-WF 3-2015-0641 1, CR-WF 3-2016-02619, and CR-WF 3-2016-02644. The licensee established work tracker system surveillances to ensure these drills are appropriately performed in 2016

. Because this violation was of very low safety significance and the licensee entered the issue into their corrective action program, thi s violation is treated as a non

-cited violation, consistent with Section 2.3.2.a of the Enforcement Policy: NCV 000382/2016002

-03, "Failure to Perform Drills Required by the Site Emergency Plan."

. Specifically, the inspectors noted four examples of plant adverse conditions where operability was evaluated incorrectly

. In all instances , inspector intervention was required for the licensee to expand the initially lacking technical assessment and ultimately produce an acceptable statement that concluded operability

. The examples included the following conditions:

CR-WF3-2016-02353 - The cable vault and switchgear area ventilation air handling unit was identified as having elevated vibrations; however, the licensee used acceptance criteria for pump vibrations to justify operability.

CR-WF3-2016-2736 - During an emergency diesel generator train B work window, the licensee identified several relay base connections that were loose

. The licensee did not provide sufficient technical justification for concluding the train A emergency diesel generator was operable and not impacted by this condition.

CR-WF3-2016-3429 - The auxiliary component cooling water pump B was declared inoperable due to rising outboard motor bearing temperatures

. The licensee did not provide sufficient technical justification to declare the pump operable based on lube oil bearing temperature limits

.

CR-WF3-2016-00736 - The reactor coolant pump 2A motor space heater was energized while the pump was running

. The licensee documented an operability evaluation for when the plant was in Mode 6, however, the plant was in Mode 1

.

In each instance, the inspectors ensured that the licensee corrected the condition and subsequently evaluated the technical issues with the technical rigor that was required to justify operability

. The inspectors discussed this trend with the licensee

. The licensee entered this issue into the corrective action program as condition report CR

. The inspectors assessed the licensee's problem identification threshold, cause analyses, extent of condition reviews and corrective actions

. The inspectors verified that the licensee appropriately prioritized the planned corrective actions and that these actions were adequate to ensure the resolution of issues that had been previously identified with the corrective action program

. In addition, the inspectors verified that condition reports were initiated in a timely manner, and were classified appropriately.

These activities constitute d completion of one annual follow-up sample as defined i n Inspection Procedure 71152.

b. Findings

Introduction

. A self-revealing, Green, non

-cited violation of Technical Specification 6.8 , "Procedures and Programs,"

occurred because the licensee did not establish adequate procedures for the operation of the emergency diesel generator s. Specifically, prior to July 7, 2015, the licensee's procedure for operating the emergency diesel generators allowed lube oil pressure to be maintained low enough to activate a design feature of the starting air system that injects starting air into the diesel cylinders, which could damage the emergency diesel generator turbocharger.

Description

. On July 7, 2015, the licensee started emergency diesel generator A in the emergency mode for testing following maintenance related to the emergency diesel generator sequencer. After operating for 31 minutes, the low lube oil pressure alarm actuated and the standby lube oil pump started

. Operators found the engine lube oil pressure low, starting air system low pressure, and standby lube oil pump running annunciators locked in on the local panel

. Operators then manually shutdown emergency diesel generator A. On July 8, 2015, operators started emergency diesel generator A in the test mode and fully loaded the diesel

. After 58 minutes, emergency diesel generator A tripped due to a failure of the turbocharger thrust bearing

. The licensee replaced the turbocharger for emergency diesel generator A and returned it to service on July 12, 2015.

The licensee found that the thrust bearing sensor for emergency diesel generator A had scorch marks and its eutectic cap wiped off, indicating contact with the thrust bearing due to thrust bearing movemen t. The licensee also found excessive clearances and cracking associated with the turbocharger thrust bearing, consistent with excessive axial loading. The licensee also found that the starting air system for the emergency diesel generators includes logic to inject starting air if there is an emergency mode start and subsequently, the diesel speed drops below 280 rpm

, or engine lube oil pressure decrease s to the low lube oil setpoint of 35 +5/

-0 psig. Following the event, the licensee concluded that the guidance in the emergency diesel generator operating procedure, OP 002, "Emergency Diesel Generator," was inappropriate

. Although the emergency diesel generators are normally operated with a lube oil pressure of approximately 50 psig, the operating procedure allowed the emergency diesel generator to be operated at any lube oil pressure greater than 35 psig

. After an emergency start, the starting air system will inject to an operating emergency diesel generator upon receipt of a low lube oil pressure signal, which could actuate at up to 40 psig. The OP-009-002 operating lube oil pressure value would allow the diesel to be normally operated at a lube oil pressure low enough to inject starting air into the running diesel, resulting in damage to the turbocharger. The inspectors noted that this vulnerability only existed in the event of an emergency start of the diesel, which occurs upon receipt of a safety

-injection actuation signal, combined with a loss of off-site power and an actual low lube oil pressure condition

.

In their review of the event, the inspectors also noted that the information regarding the design for injecting starting air at low lube oil pressures was available to the licensee in the design drawings for the emergency diesel generators

. Additionally, the vendor manual for operation of the emergency diesel generators indicated that normal operating pressure should be maintained at 50 psi g, and that control and alarm functions occurred at 35 psi g.

The licensee had a previous opportunity to identify the inadequacy of the emergency diesel generator operating procedure and the potential failure of the emergency diesel generators due to low lube oil pressures

. On January 20, 2014, the pressure regulating valves for emergency diesel generator B were replaced

. Following the replacement, normal operating lube oil pressure for emergency diesel generator B dropped from 55 psig to 38 psig

. Similar work on emergency diesel generator A in 2010 caused lube oil pressures to drop from 58 to 50 psig. Concerns regarding operating with the lowered lube oil pressures were evaluated in an apparent cause analysis as part of CR

-WF3-2014-05092, however the licensee did not recognize the potential for starting air injection into an operating emergency diesel generator during the evaluation.

Analysis.

The failure to establish adequate procedures for the operation of the emergency diesel generators was a performance deficiency

. The inspectors determined that the performance deficiency was reasonably within the licensee's ability to foresee and correct

. The inspectors concluded that the performance deficiency was more than minor, and therefore a finding, 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

. Specifically, the procedural allowance to run the emergency diesel generator lube oil pressure at the starting air injection setpoint and could have resulted in the failure of the emergency diesel generators at any time they were called upon to perform their safety function.

The inspectors used NRC Inspection Manual Chapter 0609, Attachment 4, "Initial Characterization of Findings," to evaluate the finding for its impact on the Mitigating Systems cornerstone

. The initial screening directed the inspectors to use Appendix A, "The Significance Determination Process for Findings At

-Power," to determine the significance of the finding

. Using Exhibit 2, "Mitigating Systems Screening Questions," the inspectors determined that the finding required a detailed risk evaluation because it represented the loss of a system or function. I n order to perform the detailed risk evaluation, the senior reactor analyst made the following assumptions:

The air start motors could have engaged and damaged the emergency diesel generator at any time the emergency diesel generator experienced a demand in the emergency mode

. As a result, the exposure time was one year.

When the air start motor engaged, the emergency diesel generator would be damaged and the emergency diesel generator would fail to run.

The configuration and design of the diesels were such that common cause was possible on the opposite emergency diesel generator

. As a result, the analyst set the basic event for emergency diesel generator A to TRUE.

The damage to the emergency diesel generator turbocharger would occur upon initiation of a safety injection signal followed by a loss of off

-site power

. A large break loss of coolant accident, a medium break loss of coolant accident, a steam generator tube rupture, an interfacing system loss of coolant accident, and a main feed line break were the only initiators analyzed because they would be the only initiators of significance in the Waterford SPAR model which would lead to a safety injection signal

. A main steam line break was not analyzed as this was not a risk dominant initiator for the station.

The temporary emergency diesel generators were partially credited in this analysis

. The analyst assumed these temporary emergency diesel generators were available 44 percent of the time, based on their availability in calendar year 2015, which was assumed to be representative of the time that the diesels were typically hooked up and available

. If the temporary diesel generators were not hooked up, the analyst assumed that station management would have the opportunity to decide to install the generators

. This implementation of the temporary diesel generators was represented by a human error probability basic event

. Version 8.16 of the Waterford SPAR model run on Version 8.1.4 of SPAHIRE was used to estimate the increase in core damage frequency

. This version of the SPAR model was changed to make a more accurate estimate

. The following changes were made:

The analyst updated the model to include the possibility of a consequential loss of off-site power after a large break loss of coolant accident, a medium break loss of coolant accident, a steam generator tube rupture, an interfacing system loss of coolant accident, or a main feed line break occurred

. The analyst used a template event in the SPAR library of events for the basic event parameter estimation

. The basic event mean value was 2.00E

-2 in a Constrained Non

-Informative distribution.

The analyst updated the SPAR model to remove a conservative error in the modelling of the safety injection system minimum flow logic such that the logic accurately modelled the plant configuration

. Fault tree HPR

-MNFLW was removed from the fault trees of CSR (containment spray recirculation) and HPR (high pressure recirculation) as the minimum flow logic was already correctly modelled in the train specific fault trees.

The analyst estimated the increase in core damage frequency to be 4.6E

-7/year (Green). Dominant core damage sequences were medium break losses of coolant accidents and steam generator tube ruptures with associated losses of off

-site power

. Core damage was mitigated by the remaining emergency diesel generator s. External Events

. To identify the external event loss of off

-site power initiators, the analyst reviewed the "Waterford 3 Individual Plant Examination of External Events (IPEEE)," dated July 28, 1995

. First, the analyst considered external events whose occurrence during the degraded condition could have resulted in an increase in core damage frequency

. Because the probability of these external events combined with the low probability of an event which included initiation of a safety injection signal followed by a loss of off

-site power would be very low, the analyst qualitatively screened out this combination of events as insignificant

. Next, the analyst reviewed external events for those that could cause an initiation of a safety injection signal followed by a loss of off-site power. The analyst concluded that the only plausible external event of significance which could result in this scenario was a seismic event which causes a rupture of reactor coolant system piping

. The analyst considered the low seismicity of the area and the high fragility of the reactor coolant system piping to qualitatively screen out this seismic initiator

. As a result, the analyst concluded external events were not a significant contributor to increases in core damage frequency for this performance deficiency.

Large Early Release Frequency

. The analyst used Manual Chapter 0609, Appendix H, "Containment Integrity Significance Determination Process," to estimate in the increase in large early release frequency

. The analyst assumed the finding was one that would affect both core damage frequency and large early release frequency

. Using Appendix H, only interfacing system losses of coolant accidents and steam generator tube ruptures were determined to have significant potential impact on large early release frequency. Any increase in core damage frequency resulting from interfacing system losses of coolant accidents are predominantly driven by operator actions to diagnose and isolate the leak and therefore the analyst qualitatively screened out these sequences. The increase in large early release frequency was estimated by multiplying the increase in core damage frequency from steam generator tube ruptures for the performance deficiency (estimated to be 3.9E

-8/year) by a large early release factor for steam generator tube ruptures obtained from Appendix H of Manual Chapter 0609 (with value of 1.0)

. As a result the increase in large early release frequency was estimated to be 3.9E-8/year (Green)

.

The inspectors concluded that the finding had an Evaluation cross-cutting aspect in the area of Problem Identification and Resolution because the licensee did not thoroughly evaluate issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance

. Specifically, the licensee's previous evaluation performed for operating the emergency diesel generators with low lube oil pressures did not thoroughly evaluate the risk associated with the starting air [P.2].

Enforcement

. Technical Specification 6.8, "Procedures and Programs," Section 1.a, requires, in part, that procedures shall be established, implemented and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2

. Section 3.s.(2)(a) of Regulatory Guide 1.33, Revision 2, Appendix A, recommends, in part, that instructions be established for operating the on

-site emergency power sources (e.g., diesel generators, batteries)

.

Contrary to the above, prior to July 8, 2015, the licensee did not establish appropriate instructions for operating the on-site emergency power sources

. Specifically, licensee procedure OP 002, "Emergency Diesel Generator," Revision 326 and prior, allowed maintaining emergency diesel generator lube oil pressure low enough to cause the starting air system to automatically inject into the emergency diesel generator cylinders while operating, resulting in damage to the associated emergency diesel generator turbocharger and failure of the emergency diesel generator

. The licensee entered this condition into their corrective action program as condition report CR

-WF3-2015-04459. The corrective actions taken to restore compliance was to increase the procedure OP-009-002 requirement for lube oil pressure from 35 psig to 45 psig.

Because this violation was of very low safety significance and the licensee entered the issue into their corrective action program, this violation is treated as a non

-cited violation, consistent with Section 2.3.2 of the Enforcement Policy: NCV 05000382/2016002

-04, "Failure to Account for Starting Air Design Features in Emergency Diesel Operating Procedures."

4OA 3 Follow-up of Events and Notices of Enforcement Discretion (71153)

.1 (Closed) Licensee Event Report 05000382/2015

00, "Both Emergency Diesel Generators Declared Inoperable

." On August 26, 2015, the licensee declared emergency diesel generator trains A and B inoperable

. Emergency diesel generator A was declared inoperable at 1: 11 a.m. due to the failure of a current transformer during a surveillance run resulting in a generator differential trip

. Per Technical Specification 3.8.1.1, "A.C. Sources," the licensee started emergency diesel generator B to determine extent of condition for the train A failure. At 7: 40 a.m., emergency diesel generator B was declared inoperable due to its room air intake dampers not opening

. The licensee entered Technical Specification 3.8.1.1 condition F, which required one emergency diesel generator be restored operable within two hours or the plant be in hot standby within six hours. The licensee took action to open the emergency diesel generator B room air intake dampers and restor ed emergency diesel generator B to an operable status at 10

01 a.m. In their review of the events, the inspectors did not note any performance deficiencies

. This licensee event report is closed.
