SUBJECT: INDIAN POINT POWER STATION - NRC EVALUATION OF CHANGES, TESTS, OR EXPERIMENTS AND PERMANENT PLANT MODIFICATIONS TEAM INSPECTION REPORT 05000247/2014007 AND 05000286/2014007
Dear Mr. Ventosa:
On June 20, 2014, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at the Indian Point Power Station, Units 2 and 3. The enclosed inspection report documents the inspection results, which were discussed on June 20, 2014, with Mr. John Dinelli, General Manager, Site Operations and other members of your staff.
The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your license. In conducting the inspection, the team reviewed selected procedures, calculations and records, observed activities, and interviewed station personnel.
This report documents one NRC-identified finding of very low safety significance (Green). The finding was determined to involve a violation of NRC requirements. However, because of the very low safety significance, and because the issue has been entered into your corrective action program, the NRC is treating this finding as a non-cited violation (NCV), consistent with Section 2.3.2 of the NRC Enforcement Policy. If you contest the NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U. S. Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at Indian Point.

SUMMARY
IR 05000247/2014007, 05000286/2014007; 06/02/2014 - 06/20/2014; Indian Point Power Station, Units 2 and 3; Evaluations of Changes, Tests, or Experiments and Permanent Plant
Modifications.
This report covers a 3-week Evaluation of Changes, Tests, or Experiments and Permanent Plant Modifications inspection conducted by four region-based engineering inspectors. The inspectors identified one finding of very low safety significance (Green), which was a non-cited violation (NCV). The significance of most findings is indicated by their color (Green, White,
Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process (SDP)," dated June 2, 2011. Cross-cutting aspects are determined using IMC 0310, "Aspects Within the Cross-Cutting Areas," dated December 19, 2013. All violations of NRC requirements are dispositioned in accordance with the NRC's Enforcement Policy dated July 9, 2013. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 5.
NRC-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
The team identified a Green non-cited violation of Title 10 Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion III, Design Control, because Entergy did not ensure the control air pressure regulator (IA-PCV-1548) for Unit 3 auxiliary boiler feedwater (ABFW) flow control valve BFD-FCV-406B was suited and designed to perform its safety-related function. Specifically, IA-PCV-1548 was not designed or qualified for use in the harsh environment area where it was located. Immediate corrective actions included evaluation of IA-PCV-1582 and BFD-FCV-406B to verify component operability. The issue was entered into the corrective action program as condition report IP3-2014-1364, to further evaluate both the extent-of-condition and the station's processes for maintaining configuration control over mechanical components installed in harsh environment areas.
The finding was more than minor because the finding was associated with the Design Control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of assuring the reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Additionally, the issue was similar to example 3.j in Appendix E of Inspection Manual Chapter 0612, in that the design control issue resulted in a reasonable doubt of operability. The team determined the finding was of very low safety significance (Green)because it was a design or qualification deficiency confirmed not to result in a loss of operability.
The finding had a cross-cutting aspect in the area of Human Performance, Design Margin (H.6), because Entergy did not maintain the operational temperature design margin for the control air pressure regulator to the ABFW flow control valve. The margin between the ABFW pump room peak environmental temperature and the design/qualified temperature of IA-PCV-1582 was not carefully guarded and changed only through a systematic and rigorous process.

1R17 Evaluations of Changes, Tests, or Experiments and Permanent Plant Modifications
.1 Evaluations of Changes, Tests, or Experiments (29 samples)
a. Inspection Scope
The team reviewed two safety evaluations to determine whether the changes to the facility or procedures, as described in the Updated Final Safety Analysis Report (UFSAR), had been reviewed and documented in accordance Title 10 of the Code of Federal Regulations (10 CFR) 50.59 requirements. In addition, the team evaluated whether Entergy had been required to obtain U.S. Nuclear Regulatory Commission (NRC) approval prior to implementing the c hanges. The team interviewed plant staff and reviewed supporting information including calculations, analyses, design change documentation, procedures, the UFSAR, Technical Specifications (TS), and plant drawings to assess the adequacy of the safety evaluations. The team compared the safety evaluations and supporting documents to the guidance and methods provided in
Nuclear Energy Institute (NEI) 96-07, "Guidelines for 10 CFR 50.59 Evaluations," Revision 1, as endorsed by NRC Regulatory Guide 1.187, "Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments," to determine the adequacy of the safety evaluations.
The team also reviewed a sample of twenty-seven 10 CFR 50.59 screenings for which Entergy had concluded that a safety evaluation was not 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 evaluations and screenings that Entergy had performed and approved during the time period covered by this inspection not previously reviewed by NRC inspectors. All safety evaluations since the last modifications inspection were reviewed, and the screenings and applicability determinations selected were 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 control the screening, preparation, review, and approval of safety evaluations to the guidance in NEI 96-07 to determine whether the procedures adequately implemented the requirements of
10 CFR 50.59. The reviewed safety evaluations and screenings are listed in the Attachment.
b. Findings
Commercial Grade Dedication of Control Air Pressure Regulator for Unit 3 Auxiliary Boiler Feedwater Flow Control Valve
Introduction:
The team identified a Green non-cited violation (NCV) of Title 10 Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion III, Design Control, because Entergy did not ensure the control air pressure regulator (IA-PCV-1548) for auxiliary boiler feedwater (ABFW) flow control valve BFD-FCV-406B was suited and designed to perform its safety-related function. Specifically, IA-PCV-1548 was not designed or qualified for use in harsh environment areas such as the Unit 3 ABFW room where it was located.
Description:
Commercial grade dedication (CGD) package S26992 and procurement evaluation (PE) 106118 were developed to certify commercially procured Masoneilan Model 78-4 air pressure regulators for use in safety-related applications. Unit 3 safety-related applications for this component included the ABFW flow control valves (FCVs) and emergency diesel generator air start valves. The procurement evaluation was performed as an item equivalency evaluation which evaluated this component as a replacement for five previous air pressure regulators which had become obsolete.
Procurement engineers reviewed CGD test report IP3 12N-0137 and dedicated 10 of the Masoneilan Model 78-4 air pressure regulators for safety-related use on June 18, 2012.
On March 11, 2013, one of these dedicated air pressure regulators was installed as a replacement for IA-PCV-1548 during the BFD-FCV-406B 12-year overhaul/rebuild activity (work order (WO) 52255242).
The team reviewed the procurement evaluation and associated third party CGD test report to verify that the design bases, licensing bases, and performance capability of the air pressure regulator had not been degraded. Six critical characteristics were identified and properly verified though testing. The team also reviewed WO 52255242 to determine whether the air pressure regulator was properly installed and tested.
TSP-011, Environmental Qualification (EQ) Program Harsh Areas and Service Conditions, Revision 10, classified the AFBP room as a harsh area, susceptible to a peak temperature of 244 degrees Fahrenheit (F) following a high energy line break (HELB) of the steam driven ABFW turbine steam supply line or exhaust line. The team noted PE 106118 and WO 52255242 specifically documented the following note to Planning and Maintenance: "This item is not approved for 'EQ' end-use applications."
The manufacturer specification sheet for Masoneilan mmodere regulators specified an ambient temperature range of -40 to +182F.
The team determined that, contrary to notations in PE 106118 and WO 52255242, the 78-4 air pressure regulator had been installed in a harsh environment area that it was not designed or qualified for. The team met with design engineers, procurement engineers, and the work planning supervisor to discuss the station's processes for maintaining configuration control over mechanical components installed in harsh environment areas. The team also questioned the potential effect on IA-PCV-1548 and BFD-FCV-406B operability. Engineers initiated condition report (CR) IP3-2014-1364 to perform a prompt operability determination (OD) and evaluate cause and extent-of-condition of this issue. The OD determined the air pressure regulator installed by WO 52255242 had not been designed and qualified for use in a harsh environment, such as the ABFW pump room. Four parts within the regulator could potentially be adversely affected by elevated room temperatures during a HELB in the ABFW pump room. Following further assessment of the ABFW room HELB temperature profile, material characteristics of the air pressure regulator parts, design of HELB isolation features within the ABFW pump room, and the associated short period of elevated temperature (< 1 minute) engineers concluded IA-PCV-1548 and BFD-FCV-406B would remain operable. In the unlikely event IA-PCV-1548 failed, engineers concluded the BFD-FCV-406B would fail open to its safety position and continuously feed the #32 steam generator (SG).
The team reviewed the OD and determined it was technically sound. The team further reviewed the resulting impact on operator response and on potential ABFP motor damage if the ABFP FCV failed open. The team concluded the FCV failure would complicate operator response during an event, but procedures provided adequate instruction for operators to safely maintain SG level. Additionally, procedures contained sufficient instruction to ensure operators did not stop and restart the ABFW motor too
frequently and overheat the motor.
The team performed a plant walkdown and noted Masoneilan Model 78-4 or 78-40 air pressure regulators were installed on all four of the motor driven ABFW pump FCVs. Manufacturer specifications state an ambient temperature range of -40 to +182F for both of these air pressure regulator Models. Engineers performed a more in-depth OD as part of the issue apparent cause evaluation and determined each of the 4 FCVs remained operable. Engineers informed the team CR IP3-2014-1364 would evaluate both the extent-of-condition and the station's processes for maintaining configuration control over mechanical components installed in harsh environment areas.
Analysis:
The team determined that Entergy's failure to ensure control air pressure regulator IA-PCV-1548 was designed and qualified to perform its safety-related function in the harsh environment of the Unit 3 ABFW room was a performance deficiency and a failure to meet the requirements of 10 CFR 50, Appendix B, Criterion III. Specifically, in March 2013 during a 12-year valve overhaul, Entergy installed a Masoneilan Model 78-4 air pressure regulator for safety related use in a harsh environment with a design peak temperature above the manufacturers' rating. Commercial grade dedication package S26992 did not include testing or evaluation for use in this harsh environment. The finding was more than minor because the finding was associated with the Design Control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of assuring the reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Additionally, the issue was similar to
example 3.j in Appendix E of Inspection Manual Chapter (IMC) 0612, in that the design control issue resulted in a reasonable doubt of operability.
The team evaluated the finding in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Characterization of Findings, dated June 19, 2012, for the Mitigating Systems Cornerstone, and IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated June 19, 2012. The team determined the finding was of very low safety significance (Green) because it was a design or qualification deficiency confirmed not to result in a loss of operability.
The team assigned a cross-cutting aspect associated with this finding, because the air pressure regulator was procured, commercial grade dedicated for safety-related use, and installed in the plant between June 2012 and March 2013 and was reflective of current performance. The finding had a cross-cutting aspect in the area of Human Performance, Design Margin, because Entergy did not maintain the operational temperature design margin for the ABFW FCV control air pressure regulator.
Specifically, the margin between the AFFW pump room peak EQ temperature and the design/qualified temperature of IA-PCV-1582 was not carefully guarded and changed only through a systematic and rigorous process. (H.6)
Enforcement:
Appendix B of 10 CFR 50, Criterion III, Design Control, requires in part, that design control measures shall be established to assure applicable design bases are correctly translated into specifications, procedures, and instructions. Additionally, measures shall be established for selection and review for suitability of application of materials, parts, and equipment that are essential to the safety-related functions of the structures, systems, and components. Contrary to the above, from March 11, 2013 to June 17, 2014, specifications, procedures, and work instructions were not sufficiently established to ensure control air pressure regulator IA-PCV-1582 was designed and suited for the harsh environment in which it was installed. Consequently, during performance of WO 52255242, 12-year overhaul of BFD-FCV-406B, a Masoneilan Model 78-4 air pressure regulator was installed in a harsh environment for which it was not designed or qualified. This created a reasonable doubt of the reliability and capability of BFD-FCV-406B to perform its safety function. Immediate corrective actions included evaluation of IA-PCV-1582 and BFD-FCV-406B to verify component operability.
The issue was entered into the corrective action program as CR IP3-2014-1364, to further evaluate both the extent-of-condition and the station's processes for maintaining configuration control over mechanical components installed in harsh environment areas. This violation is being treated as a NCV consistent with Section 2.3.2 of the Enforcement
Policy. (NCV 05000286/2014007-01, Deficient Design Control Results in Non-Qualified Component Installed in Harsh Environment for Unit 3 BFD-FCV-406B Actuator)

. 2.9 Modification of Unit 3 Emergency Diesel Generator Air Start Tanks and Application of Protective Coating to Internal Surfaces
a. Inspection Scope
The team reviewed nuclear engineering change EC-6665 developed to eliminate corrosion identified in the No. 31, 32 and 33 EDG starting air receivers, which had begun to foul air lines. The team also reviewed nuclear engineering change EC-9465, developed to implement the modification on the No. 33 EDG air start tank. The modification included blasting the inner tank surface to remove existing corrosion and applying a fiber-reinforced polymer coating to the internal tank surfaces, to ensure long-term integrity and corrosion protection. Application of the protective coating required the installation of a man-way in each tank to allow access to effectively apply the coating system to the internal tank surface.
The team reviewed the modification of the No. 33 EDG air start tank to determine whether the design bases, licensing bases, and performance capability of the EDG starting air system is not compromised. In addition, the team evaluated whether Entergy had been required to obtain NRC approval prior to implementing the change. The team reviewed drawing changes prepared and issued with the modification package for the tank, the support structure, and interfacing systems. The team reviewed the air tank volume calculation (IP-CALC-08-00068) to verify tank volume had not inadvertently been reduced below design requirements when the protective coating was added to the inside of the tank. The team also reviewed the seismic qualification anchorage evaluation (IP-CALC-08-00067) to verify the tank remained seismically qualified following addition of the new man way. The team interviewed engineers, reviewed maintenance work orders that installed and tested the modification, and performed a post-installation field walkdown to verify the modification was properly implemented in accordance with American Society of Mechanical EngineersSection VIII Code for Unfired Pressure Vessels. The documents reviewed are listed in the Attachment.

.2.10 Install Internal Pipe Mechanical Seals in the Unit 3 Service Water System Line #409
a. Inspection Scope
The team reviewed a nuclear engineering change EC-24032 that installed internal pipe mechanical seals at pipe weld joints in the 24 inch service water system line #409. The mechanical seals were installed in the 409 line from the service water pumps discharge manifold to the weld-o-let (installed under modification EC-19340) on the 18 foot elevation of the primary auxiliary building. The mechanical seals were designed to provide protection for the weld seams from corrosion and protect the cement lining from erosion as a result of Service Water flow. This modification, EC-24032, was worked in tandem with modification EC-19340 since EC-19340 installed two access points at a horizontal section of pipe over the discharge canal and in a vertical section of pipe in the "room with the rock." The new access points provided the means to access the buried portion of Service Water pipe line #409 for installation of approximately 57 internal pipe mechanical seals at circumferential welds. The modification identified that in order to maintain adequate SW hydraulic performance, the maximum number of installed mechanical seals was 115.
The team reviewed the modification to verify that the design basis, licensing bases and performance capability on the service water system had not been degraded by the modification. The team interviewed engineering staff and reviewed drawings, technical evaluations, and calculations associated with the modification to confirm that the system would function in accordance with the design assumptions. In addition, the team examined representative samples of the mechanical seal including the rubber sleeve and seal assembly (retaining band and wedges) and determined the seal was not part of the service water system pressure boundary. The sole function of the seal assembly was to provide a waterproof barrier to protect the weld seam locations inside of the pipe from further degradation. The team also reviewed WO 249668, which installed the modification (37 seals) in March 2011. No welding was required to install this modification. In addition, the team reviewed procedures and design basis documentation to verify that they were properly updated. The documents reviewed are listed in the Attachment.

.2.14 Unit 2 Main Steam Safety Valves Modification
a. Inspection Scope
Unit 2 has 20 main steam safety valves (MSSVs), designed to lift and relieve steam to
mitigate main steam system pressure increases during transients such as a turbine load reject or a reactor trip. Three MSSVs failed periodic in-service testing between March 2010 and March 2012. Failure analysis identified spindle wear and formation of wear-steps on the valve spindle as the most likely cause of MSSV binding, which caused the valves to lift above the maximum pressure permitted by TS. The manufacturer recommended machining the valve sleeve and installing bronze wear-sleeves in the inner diameter of the spring-washers (upper & lower) and adjusting bolts. Station engineers developed a nuclear engineering change (EC-39376 and EC-39377)
consistent with the manufacturer-recommended corrective action address MSSV spindle wear. WOs 338180 and 326508 were performed to implement and test the modification on 7 of 20 MSSVs during the March 2014 refueling outage (2R21). Modification of the remaining 13 MSSVs was planned for performance during normal scheduled preventive maintenance opportunities in the next two refueling outages (2R22 and 2R23).
The team reviewed the design modification to verify that the design bases, licensing bases and performance capability of the MSSVs and main steam system had not been degraded by the modification. The team verified that the design specifications of the modified MSSV were equivalent or improved from the original MSSVs. The team interviewed design engineers and reviewed technical evaluations, purchase specifications, drawings, maintenance records, maintenance procedures, and post-modification testing results to verify that the MSSV modification was appropriately implemented. In addition, the team review ed corrective action documents to determine if there were reliability or performance issues that may have resulted from the modification. Finally, the team walked down main steam piping and the seven modified MSSVs to assess the material condition and standby configuration. The documents reviewed are listed in the Attachment.
