Initiating Events, Mitigating Systems, and Barrier Integrity Evaluations of Chanqes. Tests. or Experiments and Permanent Plant Modifications (tP 71111.17)Evaluations of Chanoes. Tests. or Experiments (20 samples)a. Inspection Scope The team reviewed one safety evaluation to determine whether the change to the facility or procedures, as described in the Updated Final Safety Analysis Report (UFSAR), had been reviewed and documented in accordance with 10 CFR 50.59 requirements.

ln addition, the team evaluated whether Entergy had been required to obtain NRC approval prior to implementing the change. The team interviewed plant staff and reviewed supporting information including analyses, design change documentation, procedures, the UFSAR, the Technical Specifications (TS), and plant drawings to assess the adequacy of the safety evaluation.

The team compared the safety evaluation and supporting documents to the guidance and methods provided in Nuclear Energy Institute (NEl) 96-07, "Guidelines for 10 CFR 50.59 Evaluations," as endorsed by NRC Regulatory Guide 1.187 , "Guidance for lmplementation of 10 CFR 50.59, Changes, Tests, and Experiments," to determine the adequacy of the safety evaluation.

The team also reviewed a sample of nineteen 10 CFR 50.59 screenings for which Entergy had concluded that no safety evaluation was required.

These reviews were performed to assess whether Entergy's threshold for performing safety evaluations was consistent with 10 CFR 50.59. The sample included design changes, calculations, and procedure changes.The team reviewed the safety evaluation that Entergy had performed and approved during the time period covered by this inspection (i.e., since the last modifications inspection)not previously reviewed by NRC inspectors.

The 10 CFR 50.59 screenings were selected based on the safety significance, risk significance, and complexity of the change to the facility.In addition, the team compared Entergy's administrative procedures used to controlthe screening, preparation, review, and approval of safety evaluations to the guidance in NEI 96-07 to determine whether those procedures adequately implemented the requirements of 10 CFR 50.59. The safety evaluations and screenings reviewed by the team are listed in the Attachment.

b. Findinos No findings were identified.

.2 Permanent

Plant Modifications 2 (11 samples)Fuel Oil Storaqe Tank Liner Application Inspection Scope The team reviewed engineering change (EC) 24y'r04 that applied a spray-on protective liner to the bottom of fuel oil storage tank (FOST) TK'40-1A.

The FOST provides diesel fuel makeup to the emergency diesel generator (EDG) day tanks via the fuel oil transfer pumps (FOTPS). The liner covered the inside bottom of the tank and extended 24 inches vertically on the inside wall of the tank. Entergy applied the liner to simplify future tank bottom inspections and to facilitate effective corrosion control in the FOST as recommended by the American Petroleum Institute (APl).The team reviewed EC 24404 to verify that the design basis, licensing basis and performance capability of the EDG fuel oil system had not been degraded by the modification.

The team reviewed calculations, industry operating experience (OE), nondestructive examination (NDE) and liner inspection results, and liner product specifications to verify that the applied liner would not adversely impact EDG fuel oil quality or delivery.

The team reviewed the associated work order instructions and documentation to verify that Entergy implemented the modification as designed.

The team reviewed the associated post-modification test (PMT) results, system health and walkdown reports, fuel oil sample results, and conective action condition reports (CRs)to verify proper fuel oil system operation and to determine if there were reliability or performance issues that may have resulted from the modification.

The team performed a walkdown of the FOST, FOTPs, fuel oil day tanks, and EDGs to independently assess Entergy's configuration control and the material condition of the EDG fuel oil system.The documents reviewed are listed in the attachment.

b. Findinqs No findings were identified.

.2.2 Hiqh Pressure Coolant Iniection

Turbine Auxiliarv Oil Pump Replacement

a. Inspection Scope

The team reviewed modification EC 26967 that replaced the high pressure coolant injection (HPCI) system turbine auxiliary oil pump (AOP). The AOP automatically starts on HPCI initiation, to provide hydraulic power to the turbine stop valve and turbine control valves (which open to start the turbine) and to provide lubrication during startup until the shaft driven oil pump reaches sufficient speed to supply this function.

Entergy initiated this modification to upgrade the HPCI AOP based on mechanical seal leakage, potential pump re-build issues (availability of spare parts), and as a proactive measure in response to industry OE. Entergy determined that the replacement pump was nearly identical to the existing pump with a few differences (port size, shaft length, gasket a.Enclosure 3 material, and mounting flange reinforcement).

Entergy engineering evaluated these differences within EC 26967 and translated the required design changes to the EC i m plementing work order (51 07 07 40) instructions.

The team reviewed EC 26967 to verify that the design basis, licensing basis and performance capability of the HPCI system had not been degraded by the modification.

The team reviewed the associated work order instructions and documentation to verify that Entergy implemented the modification as designed.

The team reviewed the associated PMT results, system health and walkdowns reports, HPCI surveillance test results, and corrective action CRs to verify proper HPCI system operation and to determine if there were reliability or performance issues that may have resulted from the modification.

On June 5, 2012, the team observed portions of the quarterly HPCI in-service test to verify proper HPCI AOP performance.

The team performed several walkdowns of the HPCI system, including control room instrumentation, to ensure that Entergy implemented the modification in accordance with design instructions and to independently assess HPCIAOP operability, Entergy's configuration control, and the material condition of the HPCI system. The documents reviewed are listed in the attachment.

b. Findinqs No findings were identified.

.2.3 Service Water Svstem Supplv Header Inspection

Port lnstallation

a. Inspection Scope

The team reviewed modification EC 30317 that installed inspection ports in the A and B service water (SW) supply headers. Entergy committed to inspect internal sections of the piping within the SW system prior to Vermont Yankee Nuclear Power Station's period of extended operation (March 21,2012).

In order to facilitate visual examinations of the internal surfaces of SW system supply headers and evaluate their condition, Entergy installed inspection ports on the A and B SW supply headers in the intake structure.

Entergy implemented the A and B SW supply header inspection port installation under associated ECs 30318 and 30319, respectively.

Entergy used the associated ECs to track installation, testing, return to service, and update of configuration documents for each separate train because the return to service was completed at different times.The team reviewed EC 30317 and EC 30318 for the A SW supply header to verify that the design basis, licensing basis and performance capability of the SW system had not been degraded by the modification.

The team reviewed the work order instructions and documentation to verify that Entergy implemented the modification as designed.

The team reviewed the associated PMT results, system health and walkdowns reports, and corrective action CRs to verify proper SW system operation and to determine if there were reliability or performance issues that may have resulted from the modification.

The team performed several walkdowns of the SW piping in the intake structure to ensure that Entergy implemented the modification in accordance with design instructions and to Enclosure b.4 independently verify that the modified SW system configuration did not adversely affect the structural integrity of the piping, pipe supports, and system pressure boundary.

The documents reviewed are listed in the attachment.

Findinos No findings were identified.

Seismic Monitor Replacement lnspection Scope The team reviewed modificationEC 21268 that replaced the seismic monitor. The function of the seismic instrumentation system is to provide timely evaluation of a seismic event. In March 2010, Entergy identified reliability concerns with the communication between the installed seismic instrumentation and the control room workstation.

Entergy determined that the installed seismic monitor was obsolete and spare parts were not available.

Modification EC 21268 replaced the installed seismic monitor with an upgraded model, upgraded the associated modems used for communication between the monitor and the control room workstation, and upgraded the control room workstation with a new computer and printer.The team reviewed EC 21268 to verify that the design basis, licensing basis and performance capability of the seismic instrumentation system had not been degraded by the modification.

The team reviewed the associated work order instructions and documentation to verify that Entergy implemented the modification as designed.

The team interviewed operators and reviewed the associated PMT results, recent functional tests, associated operating and event response procedures, and corrective action CRs to verify proper seismic instrumentation system operation and to determine if there were reliability or performance issues that may have resulted from the modification.

The team performed several walkdowns of the seismic instrumentation system, including the control room seismic monitor workstation, to independently assess seismic instrumentation system standby readiness, the seismic monitor's operating environment, and the material condition of the system. The documents reviewed are listed in the attachment.

Findinos No findings were identified.

Restoration of Fire Barrier for DG-1-1A Inspection Scope The team reviewed modification EC 33731 that sealed several open electrical conduit floor penetrations in the A' Emergency Diesel Generator (EDG) room floor fire barrier 21. The modification was performed because Entergy identified in condition report CR-WY-2011-05507 that EDG-1A electrical conduit penetrations were not sealed with Enclosure a.b..2.5 a.

5 the required fire rated material.

The Vermont Yankee Fire Hazard Analysis (FHA) and Safe Shutdown Capability Analysis (SSCA) require these floor openings to be sealed with 3-hour fire rated material to mitigate the hazard presented by an EDG room fire.Penetrations through these barriers, including conduit and piping, need to be sealed or closed to provide a fire resistance rating at least equal to that of the fire barrier itself.The team assessed if the modification was consistent with requirements in the design and licensing bases. The team conducted interviews with the responsible engineer and performed a walkdown of the area and fire barriers affected by this modification.

The team reviewed calculations and the associated technical evaluation to assess whether the modification was consistent with design assumptions.

Additionally, the team reviewed the Fire Protection Engineering Evaluation to verify the material used to seal the open penetrations met the minimum required three hour fire rating. The team verified the requirement for de-rating cable ampacity for cables routed through fire barriers was evaluated in Entergy's analysis and cable ampacity was not adversely affected.

The team also verified that affected plant design drawings and calculations were properly updated. The documents reviewed are listed in the attachment.

b. Findinos No findings were identified.

.2.6 RHR Shutdown Coolinq Inboard lsolation

Valve Motor Maqnesium Rotor Replacement a. lnspection Scope The team reviewed modification EC 23301 that replaced the motor for motor operated valve (MOV) V10-18, residual heat removal (RHR) shutdown cooling inboard isolation valve. The seismically qualified and safety-related V10-18 motor is located in the containment structure and is credited to close the valve for primary containment and reactor vessel isolation actuation signals. The modification was initiated because Entergy had identified motor degradation during the RF028 refueling outage inspection and determined that motor replacement was required.

During RFO29, the motor was replaced with an equivalent motor that was refurbished and certified by a qualified vendor that met the quality assurance program requirements of 10 CFR Part 50, Appendix B.The team reviewed the modification to verify that the design and licensing bases of the RHR valve had not been degraded by the motor change. The team conducted interviews with the engineering staff and reviewed the design modification package to ensure that the replacement motor had similar electrical characteristics of the previously installed motor. The team verified that the impact of the change was adequately evaluated for power consumption, cable protection, voltage drop, and overload condition protection and short circuit protection requirements.

The team also verified that affected plant design drawings and calculations were properly updated. Finally, the team reviewed post maintenance testing to determine if the motor and valve would operate as Enclosure 6 required and to verify that the replacement motor did not affect the minimum closing rate for the valve as specified in the W Updated Final Safety Analysis Report (UFSAR). The documents reviewed are listed in the attachment.

b. Findinss No findings were identified.

.2.7 Replacement

of Large Power Cables Inspection Scope The team reviewed modification EC 13130 that replaced two large power cables, each cable consisting of three single conductors (350 MCM), feeding 4160V Bus 4 from the'A' Diesel Generator, DG-1-1A. The diesel generators and auxiliary systems provide class 1E electrical power to the emergency buses in a loss-of-normal power (LNP)condition or a loss-of-coolant accident (LOCA) coincident with LNP/degraded grid voltage at the emergency buses. The modification was performed as a result of analysis of an identified damaged condensate pump motor cable (condition report CR-WY-2008-02929), which determined that it had reached end of life. Entergy determined that the diesel generator cables were installed approximately the same time as the damaged condensate pump motor cable. Although equipment run-time and environment conditions were not similar, Entergy conservatively decided to replace all4l(/ cables as equipment became available.

The team reviewed the modification to verify it was consistent with design and licensing bases requirements.

The team reviewed the replacement cable properties, such as cable insulation ratings, cable current carrying capacity, cable resistance and reactance, and reviewed the associated short circuit calculation to ensure that changes were adequately incorporated into the design analysis and bounded by the current design.The team verified that seismic loading of existing raceways was not affected by this modification.

The team conducted interviews with the engineering staff and performed a walkdown of the affected components.

The team reviewed the implementing work order to ensure that it was consistent with the change package, and to ensure that proper post maintenance testing was performed and that the documented results were acceptable.

The team also verified that affected plant design drawings and calculations were properly updated. The documents reviewed are listed in the attachment.

Findinqs No findings were identified.

.2.8 RCIC MOV V1 3-30 Motor Replacement

Inspection Scope The team reviewed modification EC17858 that replaced the motorfor MOV V13-30, reactor core isolation cooling (RCIC) system test return valve to the condensate storage Enclosure a.b.a.

7 tank (CST). The modification was performed to resolve a 60VDC ground concern associated with the valve motor circuitry.

Entergy identified within condition report, CR-WY-2009-02680, that an electricalground associated with the 250 VDC supply panel (DC-2) had been traced to the motor for the valve. The RCIC system performs a function to supply makeup water to the reactor vessel to maintain sufficient inventory.

This ensures that adequate core cooling is provided following a reactor vessel isolation event accompanied by a loss of feedwater, or following a loss of all auxiliary power. The RCIC test return valve is normally closed and if opened for system testing, automatically closes on a RCIC system initiation to allow full injection flowrate back to the vessel.During the review of the EC to replace the motor, the team also reviewed the associated operability evaluation performed by Entergy to address the degraded ground condition.

This included review of the interim compensatory measures established by Entergy at the time to ensure the valve remained closed to ensure rated RCIC flow to the reactor upon an initiation signal.The team reviewed the modification to verify that the design and licensing bases of the valve had not been degraded by the motor change. The team conducted interviews with the engineering staff and reviewed the design modification package to ensure that the replacement motor had similar electrical characteristics to the previously installed motor.The team verified that the impact of the change was adequately addressed for power consumption, voltage drop, cable protection, and overload condition and short circuit protection requirements.

The team also verified that affected plant design drawings and calculations were properly updated. Finally, the team reviewed post maintenance testing results to verify the motor and valve would operate as required.

The documents reviewed are listed in the attachment.

b. Findinss No findings were identified.

.2.9 Replacement

of the C RHRSW Pump Rotatins Assemblv.

P-8-1C

a. Inspection Scope

The team reviewed modification EC 15733 which replaced the'C' residual heat removal service water (RHRSW) pump rotating assembly.

The modification was performed to replace the carbon steel pump rotating assembly with microbiologically influenced corrosion (MlC) resistant materialto assist in improving pump performance and overall reliability.

The RHRSW pump performance had previously shown some deterioration due to corrosion attack from MIC due to exposure to raw river water. Entergy had determined that the new RHRSW rotating assembly had an associated maximum horsepower which exceeded the previously installed coupled motor nameplate horsepower rating. The team reviewed the increase in horsepower rating to ensure Entergy had appropriately revised calculations associated with diesel generator loading and the increased heat load added to the emergency core cooling system (ECCS)corner rooms. The team reviewed the calculations to ensure that design and licensing bases requirements associated with the equipment were maintained.

8 The team reviewed affected procedures such as alarm response sheets which were impacted due to the potentialfor higher operating RHRSW pump motor cunents to ensure they were adequately revised. The team reviewed the post modification pump test results to ensure that pump performance remained above the minimum required flowrate and pressure established in design calculations.

Additionally the team reviewed the associated in-service testing results to ensure the pump performed within established acceptance criteria.

The team reviewed the replacement pump rotating assembly minimum flow requirements to ensure that operational procedures ensured this minimum flow requirement would be maintained during RHRSW pump operation.

The team reviewed post modification testing to ensure that the assumed increase in motor electrical loading had been conservative.

The team reviewed the implementing work order for the modification to ensure that the replacement pump assembly had been installed consistent with the engineering change assumptions.

The team performed a walkdown of the pump to ensure the installed configuration was consistent with the EC requirements.

Additionally, the 10 CFR 50.59 screening determination associated with this modification was also reviewed as described in section 1R17

.1 of this report. The documents

reviewed are listed in the attachment.

b. Findinqs No findings were identified

.2.10 Vent Valve Installation

in 'A' RHR Torus Suction Line lnspection Scope The team reviewed modification EC 13969 that installed an air vent valve in the 'A' RHR torus suction line. This modification was performed to allow for venting air that can be entrained in the inverted U piping configuration between the torus and the pump suction isolation valve. A single isolation, locked closed and capped vent valve was installed as part of the 'A' RHR to torus suction piping pressure boundary.The team reviewed Entergy's method used to installthe vent assembly to ensure the welding procedures and pressure testing were in accordance with code requirements.

The team reviewed the process requirements contained within the design package to ensure installation of the valve using the hot tap procedure was consistent with engineering requirements.

The team reviewed the structural calculation associated with the change to ensure the new branch line and valve were adequately evaluated for loading conditions and pipe stresses remained within code requirements.

The team reviewed affected procedures and drawings to ensure they were adequately revised to reflect the modification.

The team performed a walkdown to ensure the installed valve configuration was consistent with the engineering change package. Additionally, the 10 CFR 50.59 screening determination associated with this modification was also reviewed as described in section 1R17.1 of this report. The documents reviewed are listed in the attachment.
