SUBJECT:

QUAD CITIES NUCLEAR POWER STATION, UNITS 1 AND 2 - EVALUATIONS OF CHANGES, TESTS, AND EXPERIMENTS AND PERMANENT PLANT MODIFICATIONS BASELINE INSPECTION REPORT 05000254/2016008; 05000265/2016008

Dear Mr. Hanson:

On August 26, 2016, the U.S. Nuclear Regulatory Commission (NRC) completed an Evaluations of Changes, Tests, and Experiments, and Permanent Plant Modifications inspection at your Quad Cities Nuclear Power Station, Units 1 and 2. The enclosed inspection report documents the inspection results, which were discussed on August 26, 2016, with Mr. S. Darin, and other members of your staff.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations, and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

Based on the results of this inspection, one NRC-identified and one self-revealed findings of very-low safety significance were identified. Both were determined to involve violations of NRC requirements. However, because of their very-low safety significance, and because the issues were entered into your Corrective Action Program, the NRC is treating the issues as Non-Cited Violations (NCVs) in accordance with Section 2.3.2 of the NRC Enforcement Policy.

If you contest the subject or severity of the NCV, 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 III; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Quad Cities Nuclear Power Station.

In addition, if you disagree with the cross-cutting aspect assigned to any finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region III, and the NRC Resident Inspector at the Quad Cities Nuclear Power Station. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390, Public Inspections, Exemptions, Requests for Withholding, of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS)

SUMMARY

Inspection Report 05000254/2016008; 05000265/2016008; 08/08/2016 - 08/26/2016; Quad

Cities Nuclear Power Station, Units 1 and 2; Evaluations of Changes, Tests, and Experiments and Permanent Plant Modifications.

This report covers a 2-week announced baseline inspection on evaluations of changes, tests, and experiments, and permanent plant modifications. The inspection was conducted by Region III based engineering inspectors. One U.S. Nuclear Regulatory Commission (NRC) identified and one self-revealed findings of very-low safety significance were identified. Both of which were considered Non-Cited Violations (NCVs) of NRC regulations. The significance of most findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) using Inspection Manual Chapter 0609, Significance Determination Process. Cross-cutting aspects were determined using Inspection Manual Chapter 0310, Aspects within the Cross-Cutting Areas.

Findings for which the Significance Determination Process does not apply may be Green, or be assigned a severity level after NRC management review. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy, dated July 9, 2013. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 5, dated February 201

NRC-Identified

and Self-Revealed Findings Cornerstones: Initiating Events, Mitigation Systems, and Barrier Integrity

Green.

A finding of very-low safety significance (Green) and an associated NCV of Technical Specification 5.4.1.a, Procedures, was self-revealed on December 2, 2014 when procedural guidance failed to be implemented as written. Specifically, Procedure QCOA 6100-17, Revision 12, Loss of SBO [Station Black-Out Normal 13.8kV Transformer T42R-6 Feed to 4kV Bus 61 and 71, included inappropriate guidance to cross-tie Bus 61 and Bus 71. The licensees procedural guidance as written were technically infeasible and could not be implemented due to breaker interlocks caused by the digital control system interface that precluded the 4kV buses 61 and 71 from being cross-tied. The licensee entered this finding into their Corrective Action Program as Issue Report 2487426 and Issue Report 2706435 and removed the guidance to cross-tie the 4KV buses from the procedure.

The performance deficiency was determined to be more-than-minor because it was associated with the Mitigating System cornerstone attribute of design control and adversely affected the cornerstone objective of ensuring the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The finding screened as of very-low safety significance (Green) because it did not result in the loss of operability or functionality of any structure, system, or component. Specifically, using other procedural guidance, operators were able to start both station black-out diesels within the hour. The inspectors did not assign a cross-cutting aspect associated with this finding because it was not confirmed to reflect current performance. (Section 1R17.1.b.)

Green.

The inspectors identified a finding of very-low safety significance (Green) and an associated NCV of Title 10 of the Code of Federal Regulations, Part 50, Appendix B,

Criterion III, Design Control, for licensees failure to assure that quality standards for the Target Rock Relief valve accumulator were specified and included in the design documents and that deviations were identified and controlled. Specifically, Engineering

Change (EC 394119) fabricated the replacement Unit 2 Target Rock valve accumulator to American National Standard B31.1 Power Piping code requirements instead of the applicable American Society of Mechanical Engineers Boiler and Pressure Vessel Code,

Section VIII requirements, without adequate justifications. The licensee captured this issue in their Corrective Action Program as IR 02708406 to evaluate the appropriate corrective actions and revise documentation as required.

The performance deficiency was determined to be more-than-minor because it was associated with the Mitigating System cornerstone attribute of design control and adversely affected the cornerstone objective to ensure the availability, and reliability of systems that respond to initiating events to prevent undesirable consequences. The finding screened as of very-low safety significance (Green) because it did not result in the loss of operability or functionality of any affected structure, system, or components.

This finding has a cross-cutting aspect in the area of Human Performance in the area of Design Margin because the licensee failed to maintain equipment within its design margins. (Section 1R17.2.b.) [H.6]

REACTOR SAFETY

Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity

1R17 Evaluations of Changes, Tests, and Experiments and Permanent Plant Modifications

.1 Evaluation of Changes, Tests, and Experiments

a. Inspection Scope

The inspectors did not review any safety evaluation performed pursuant to Title 10 of the Code of Federal Regulations (CFR), Part 50.59 because the licensee did not perform any safety evaluation during the triennial sample period. The inspectors reviewed 19 screenings and/or applicability determinations where licensee personnel had determined that a 10 CFR 50.59 evaluation was not necessary. The inspectors reviewed these documents to determine if:

the changes, tests, and experiments performed were evaluated in accordance with 10 CFR 50.59, and that sufficient documentation existed to confirm that a license amendment was not required; the safety issue requiring the change, tests or experiment was resolved; the licensee conclusions for evaluations of changes, tests, and experiments were correct and consistent with 10 CFR 50.59; and the design and licensing basis documentation was updated to reflect the change.

The inspectors used, in part, Nuclear Energy Institute 96-07, Guidelines for 10 CFR 50.59 Implementation, Revision 1, to determine acceptability of the completed evaluations, and screenings. The Nuclear Energy Institute document was endorsed by the U.S. Nuclear Regulatory Commission in Regulatory Guide 1.187, Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments, dated November 2000. The inspectors also consulted Part 9900 of the U.S. Nuclear Regulatory Commission Inspection Manual, 10 CFR Guidance for 10 CFR 50.59, Changes, Tests, and Experiments.

The minimum sample size of 6 safety evaluations were not achieved, because the licensee did not perform any safety evaluation during the triennial sample period.

Therefore, this inspection constituted only 19 samples of screenings and/or applicability determinations as defined in Inspection Procedure 71111.17-04.

b. Findings

Failure to Provide Appropriate Operating Instructions for Aligning a Battery Charger to the Station Black-Out Diesel Generator

Introduction:

A finding of very low-safety significance (Green) and associated Non-Cited Violation (NCV) of Technical Specification 5.4.1.a, Procedures, was self-revealed on December 2, 2014 when procedural guidance failed to be implemented as written.

Specifically, Procedure QCOA 6100-17, Revision 12, Loss of SBO Normal 13.8kV Transformer T42R-6 Feed to 4kV Bus 61 and 71, included inappropriate guidance to cross-tie Bus 61 and Bus 71. The licensees procedural guidance as written was technically infeasible and could not be implemented due to breaker interlocks caused by the digital control system interface that precluded the 4kV buses 61 and 71 from being cross-tied.

Description:

Prior to August 2013, Procedure QCOA 6100-17, Loss of SBO [Station Black-Out] Normal 13.8kV Transformer T42R-6 Feed to 4kV Bus 61 and 71, provided instructions in response to a loss of normal power to the SBO buses which included a start of one of the SBO Diesel Generators to provide power to its associated bus and connecting the maintenance spare charger to provide power to the other SBO battery.

The licensee implemented a procedure revision to Procedure QCOA 6100-17, Revision 12, which instructed operations personnel to cross-tie 4kV bus 61 and 71 in the event of a loss of normal 13.8kV power. The licensee performed this procedure change as an enhancement to provide additional margin for the time critical action of aligning a battery charger to the SBO Diesel Generator batteries within one hour as this action was considered challenging to complete within one hour. This cross-tie would energize the battery chargers for both SBO Diesel Generators and ensure that the batteries remained charged to support the availability of the SBO Diesel Generators. The procedure provided instructions to start one of the SBO Diesel Generators and actions from inside and outside the control room to attempt to cross-tie both SBO buses (Bus 61 and Bus 71). In September 2015, during a planned maintenance activity when the 13.8kV bus was taken out of service for maintenance, it was self-revealed that breaker interlocks prevented 4kV bus 61 and 71 from being cross-tied. Specifically, operations staff attempted to cross-tie 4kV bus 61 and 71, as instructed by the procedure, when the 13.8kV bus was out of service; however, the operations staff discovered that the cross-tie breaker would not close. Based on operators knowledge of plant equipment and their training, the Operators were able to start both SBO Diesel Generators within an hour using other procedural guidance. Subsequent investigation by the licensee revealed that breaker interlocks in the digital control system for the SBO Diesel Generator precluded the cross-tie of 4kV bus 61 and 71. The licensee initiated Assignment Report (AR) 2487426 and AR 2706435 to document this issue with the procedure. The licensees immediate corrective action included revising the procedure to remove the guidance to cross-tie 4kV Bus 61 and 71.

Analysis:

The inspectors determined that the failure to provide appropriate instructions to ensure that a battery charger to each SBO Diesel Generator was aligned within an hour, in the event of loss of power to SBO buses, was contrary to the requirements of Technical Specification 5.4.1.a, Procedure, and was a Performance Deficiency.

Specifically, Procedure QCOA 6100-17 provided inappropriate steps to cross-tie buses 61 and 71 which were not feasible due to breaker interlocks that precluded the cross-tie of buses 61 and 71. As a result, these procedural steps could further complicate the already challenging time-critical action of aligning a battery charger to the SBO Diesel Generator battery within one hour.

The performance deficiency was determined to be more-than-minor because the finding was associated with the Mitigating Systems cornerstone attribute of procedure quality and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, this performance deficiency challenged the ability of the operators to restore power to the SBO Diesel Generator batteries within one hour, and, consequently, could have challenged the availability, reliability, and capability of the SBO Diesel Generators in the event of a loss of the 13.8 kV bus.

In accordance with Inspection Manual Chapter (IMC) 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, Table 2 the inspectors determined the finding affected the Mitigating Systems cornerstone. As a result, the inspectors determined the finding could be evaluated using Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 2 for the Mitigating Systems cornerstone. The finding screened as having very-low safety significance (i.e., Green) because it did not result in the loss of operability or functionality of any structure, system, or component. Specifically, per the operators knowledge and training, the licensee was able to use other procedural guidance that started both SBO Diesel Generators within one hour.

The inspectors did not identify a cross-cutting aspect associated with this finding because the finding was not representative of current performance. Specifically, the inappropriate procedural steps to cross-tie buses 61 and 71 were added in August 2013.

Enforcement:

Technical Specification Section 5.4.1.a Procedures, requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978.

Regulatory Guide 1.33, Appendix A, Section 6, addresses Procedures for Combating Emergencies and Other Significant Events and Section 6.c, addresses Loss of Electrical Power (and/or degraded power sources). Procedure QCOA 6100-17, Loss of SBO Normal 13.8kV Transformer T42R-6 Feed to 4kV Bus 61 and 71, was the implementing procedure to response to loss of electrical power to the SBO buses.

Contrary to the above, from August 14, 2013, until September 16, 2015, the licensee failed to maintain a written procedure covering loss of electrical power (and/or degraded power sources). Specifically, the licensee failed to maintain Procedure QCOA 6100-17, Loss of SBO Normal 13.8kV Transformer T42R-6 Feed to 4kV Bus 61 and 71, such that it provided appropriate guidance on how to align a battery charger to each SBO diesel generator battery within an hour from the loss of power event to these buses.

This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy because it was of very low safety significance and was entered into the licensees Corrective Action Program (CAP) as Issue Report 2487426 and 2706435.

The licensees immediate corrective action included revising the procedure to remove the guidance to cross-tie 4kV Bus 61 and 71. (NCV 05000254/2016008-01; 05000265/

2016008-01, Failure to Provide Appropriate Operating Instructions for Aligning a Battery Charger to the Station Black-Out Diesel Generator).

.2 Permanent Plant Modifications

a. Inspection Scope

The inspectors reviewed 15 permanent plant modifications that had been installed in the plant during the last 3 years. This review included in-plant walkdowns for portions of EC 385177, 1B-RHRSW Piping Replacement for Piping Installation, and EC 401167, Upgrade Unit 2 Secondary Containment Interlock Doors 2-0020-152 and 2-0030-119, and the 250 Vdc battery room. The modifications were selected based upon risk significance, safety significance, and complexity. The inspectors reviewed the modifications selected to determine if:

the supporting design and licensing basis documentation was updated; the changes were in accordance with the specified design requirements; the procedures and training plans affected by the modification have been adequately updated; the test documentation as required by the applicable test programs has been updated; and post-modification testing adequately verified system operability and/or functionality.

The inspectors also used applicable industry standards to evaluate acceptability of the modifications. The list of modifications and other documents reviewed by the inspectors is included as an Attachment to this report.

This inspection constituted 15 permanent plant modification samples as defined in Inspection Procedure 71111.17-04.

b. Findings

Failure to Evaluate the Target Rock Relief Valve Accumulator per American Society of Mechanical Engineers Code

Introduction:

The inspectors identified a finding of very-low safety significance (Green),and an associated NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the licensees failure to assure that quality standards for the Target Rock Relief valve accumulator were specified and included in the design documents and that deviations were identified and controlled. Specifically, Engineering Change (EC 394119) fabricated the replacement Unit 2 Target Rock valve accumulator to American National Standard (ANSI) B31.1 Power Piping code requirements instead of the applicable American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section VIII, requirements, without adequate justifications.

Description:

Previous Component Design Basis Inspection identified that a critical parameter in calculation NUC-60, "Air Accumulator System Analysis to Ensure Operability in loss of coolant accident for 1(2)-0203-3AB at Quad Cities, was not correct. This error impacted the margin available in the number of strokes which the accumulator can support. One of the adjustable parameters in this calculation was the size of accumulator. In order to resolve this issue, the licensee replaced the existing accumulators in both units, which resulted in increasing the capacity and adding margin to the system. The replacement accumulators were fabricated using piping material capped at both ends per design modification EC 392761 (accumulator 1-0203-3AB, Unit 1) and EC 394119 (accumulator 2-0203-3AB, Unit 2). The original accumulators were 4 inches in diameter. Replacement for Unit 1 was a 4 inch diameter accumulator, however, the replacement Unit 2 accumulator size was increased to 8 inches due to seismic qualification of the piping which required the accumulator to be shorter in length.

Based on the information provided by the licensee, the existed accumulators were fabricated under specification K-2202, which required the drywell air piping to the target rock valve operator to be classified, constructed, and tested per ANSI B31.1, 1973 code.

In reviewing EC 394119, which had referenced the ANSI B31.1 code edition 1967, the inspectors noted the following:

According to Subsection 100.1.3.B of the 1967 as well as 1973 editions of B31.1, this code did not apply to economizers, heaters, tanks, nuclear reactor vessels and other pressure vessels covered by Sections of the ASME Boiler and Pressure Vessel Code.

The licensee indicated that the general code of construction was ASME Section VIII, 1965, when applicable. Per Section U-1.d(5) in the 1965 and 1968 editions of ASME Section VIII, vessels having an inside diameter not exceeding 6 inches were not within jurisdiction of this division of Section VIII.

Based on the above, since the original as well as the Unit 1 replacement were all less than 6 inches in diameter, they were exempt from the ASME Section VIII requirements and therefore could be fabricated per ANSI B31.1 requirements.

However, when the licensee increased the Unit 2 replacement accumulator size from 4 inch to 8 inch diameter, the exemption was no longer applicable and therefore the accumulator needed to meet the ASME Section VIII requirements.

Design Consideration Summary Section 4.1.7 in EC 394119 incorrectly stated that the accumulator was exempt from ASME Section VIII requirements due to its size.

Upon identification of the concern, while acknowledging incorrect application of the size exemption, the licensee contended that a later version of the ASME code provided an additional exemption that could be applied in this case. Specifically, the licensee referred to the 1989 edition of the Section VIII code, subsection U-1 (c)(5) that excludes the following components from within the scope of this division: piping components, such as pipe flanges, bolting, gaskets, valves expansion joints, fittings, and the pressure containing parts of other components, such as strainers and devices which serve such purposes as mixing, separating, snubbing, distributing, and metering flow, provided that pressure containing parts and components are generally recognized as piping components or accessories. The inspectors did not agree with the licensees interpretation that the accumulator would be a part of the category describe under the exemption and further noted that using a later edition would require the licensee to perform a code reconciliation.

Based on the above, the inspectors concluded that the licensees determination that the ASME Section VIII requirements were not applicable was not justified. The inspectors reviewed and discussed the additional information provided by the licensee during a conference call with the licensee and reiterated their position that the Engineering Change (EC 394119) failed to verify that the design specification and codes for the original 4 inch accumulator were still applicable and valid for the replacement 8 inch accumulator.

The licensee entered this issue into their CAP as Issue Report 02708406 to evaluate the appropriate corrective actions and revise documentations as required.

Analysis:

The inspectors determined the licensees failure to evaluate the Target Rock Relief valve accumulator per ASME Section VIII requirements was contrary to 10 CFR Part 50, Appendix B, Criterion III, Design Control, and was a performance deficiency. Specifically, the licensee failed to recognize that the size exemption under ASME Section VIII no longer applied to the replacement 8-inch diameter accumulator for Unit 2. EC 394119 also failed to verify that the original 4-inch design specification was still valid for the replacement accumulator and hence failed to provide justification as to why the 8 inch replacement did not need to meet the ASME Section VIII code requirement.

The performance deficiency was determined to be more than minor because it was associated with the Mitigating System cornerstone attribute of design control and adversely affected the cornerstone objective to ensure the availability and reliability of a system that responds to initiating events to prevent undesirable consequences.

Specifically, the licensees failure to evaluate the design for the replacement 8 inch diameter accumulator per the ASME Section VIII requirements, or to ensure that the design specification for the original 4 inch accumulator was not affected and would still apply to the replacement 8 inch accumulator did not ensure that the replacement 8 inch accumulator was fabricated correctly per the applicable codes.

In accordance with IMC 0609, Significance Determination Process, IMC 0609.04

, Initial Characterization of Findings, Table 2, the inspectors determined the finding affected the Mitigating Systems cornerstone because it affected the Automatic Depressurization System, a system used for long term heat removal. As a result, the inspectors determined the finding could be evaluated using Appendix A, The SDP for Findings At-Power, Exhibit 2, for the Mitigating Systems cornerstone screening questions. The inspectors answered Yes to Question 1 because the finding did not result in the loss of operability or functionality of any affected structure, system, or component. Specifically, weld Non-Destructive Examinations and the leak tests performed during and after the installation provide reasonable assurance for operability of the system. The finding screened as having very-low safety significance (Green).

The finding screened as having very-low safety significance (Green).

The inspectors determined this finding had an associated cross-cutting aspect, Design Margins (IMC 0310, Item H.6), in the Human Performance cross-cutting area because of the licensees failure to maintain equipment within its design margins. Specifically, the licensee failed to verify that the design margin was maintained by application of appropriate quality requirements when the accumulator size was increased.

Enforcement:

Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, requires, in part, that measures shall be established to assure applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures and instructions. These measures shall include provisions to assure that appropriate quality standards are specified and that deviations from such standards are controlled.

Contrary to the above, in April 2014, the licensee failed to assure that the applicable quality standards were translated into specification K-2202 for the Target Rock Relief valve replacement accumulator approved in Revision 001 of EC 394119. Specifically, the licensee did not incorportate the applicable design basis standard (ASME Boiler and Pressure Vessel code,Section VIII) for fabrication of the accumulator vessel into the design specification K-2202. Consequently, the licensee fabricated the accumulator in accordance with the incorrect standard (ANIS B31.1 piping code).

This was not an immediate safety concern because weld Non-Destructive Examinations and the leak tests performed during and after the installation provided reasonable assurance for operability of the system. This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy because it was a very-low safety-significant and was entered into the licensees CAP as Issue Report 02708406 with the action to evaluate the appropriate corrective actions and revise documentation as required. (NCV 05000254/2016008-002; 05000265/2016008-002, Failure to Evaluate the Target Rock Relief Valve Accumulator per ASME Code.)
