SUBJECT:
QUAD CITIES NUCLEAR POWER STATION, UNITS 1 AND 2 NRC INTEGRATED INSPECTION REPORT 50-254/03-03; 50-265/03-03
Dear Mr. Skolds:
On March 31, 2003, the U. S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Quad Cities Nuclear Power Station, Units 1 and 2. The enclosed report documents the inspection findings which were discussed on April 1, 2003, with Mr. Tulon 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, the inspectors identified four issues of very low safety significance (Green). Three of these issues were determined to involve violations of NRC requirements. However, because of their very low safety significance and because they have been entered into your corrective action program, the NRC is treating these issues as Non-Cited Violations in accordance with Section VI.A.1 of the NRCs Enforcement Policy.
If you contest the subject or severity of these Non-Cited Violations, 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 Regulation Commission, ATTN: Document Control Desk, Washington, DC 20555-001, with a copy to the Regional Administrator, U.S. Nuclear Regulatory Commission -
Region III, 801 Warrenville Road, Lisle, IL 60532-4351; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the Resident Inspector Office at the Quad Cities Nuclear Power Station.
Since the terrorist attacks on September 11, 2001, the NRC has issued two Orders (dated February 25, 2002, and January 7, 2003) and several threat advisories to licensees of commercial power reactors to strengthen licensee capabilities, improve security force readiness, and enhance access authorization. The NRC also issued Temporary Instruction 2515/148 on August 28, 2002, that provided guidance to inspectors to audit and inspect licensee implementation of the interim compensatory measures (ICMs) required by the plants during calendar year (CY) 02, and the remaining inspections are scheduled for completion in CY 03. Additionally, table-top security drills were conducted at several licensees to evaluate the impact of expanded adversary characteristics and the ICMs on licensee protection and mitigative strategies. Information gained and discrepancies identified during the audits and drills were reviewed and dispositioned by the Office of Nuclear Security and Incident Response.
For CY 03, the NRC will continue to monitor overall safeguards and security controls, and conduct inspections, and will resume force-on-force exercises at selected power plants. Should threat conditions change, the NRC may issue additional Orders, advisories, and temporary instructions to ensure adequate safety is being maintained at all commercial power reactors.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS
IR 05000254/2003-003, 05000265/2003-003; Exelon Nuclear; on 12/29/02-03/31/03, Quad
Cities Nuclear Power Station; Units 1 & 2. Fire Protection, Non-Routine Evolutions, and Event Followup.
This report covers a 3-month period of baseline resident inspection and announced baseline inspections on emergency preparedness and radiation protection. The inspection was conducted by Region III inspectors and the resident inspectors. The inspection identified four Green findings, of which three were considered Non-Cited Violations. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July 2000.
A. Inspector-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
The inspectors identified a finding involving a Non-Cited Violation for the licensees failure to maintain 80 feet of spatial separation between a flammable liquids storage cabinet and the furthest diesel fire pump as required by the Quad Cities Operating Licenses and the Fire Protection Program.
The inspectors concluded that this finding was more than minor because the improper cabinet placement and potential storage of a large amount of flammable materials could lead to a fire which could engulf both fire pumps and cause a loss of the non safety-related service water system and the circulating water system. In addition, this finding was associated with the initiating events cornerstone attribute of protecting the plant against external factors and impacted the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions. The finding was of very low safety significance based on the determination that the actual stored flammable liquids, if inadvertently ignited, would not produce sufficient radiative heat flux to damage both fire pumps at the same time. (Section 1R05.1)
- Green.
The inspectors identified a finding involving a human performance error that resulted in the loss of the safety function of the Unit 2 reactor core isolation cooling system. An individual inadvertently bumped the systems trip throttle mechanism while removing scaffolding from the area.
The inspectors determined that the finding was more than minor because it impacted the mitigating systems attributes and objectives. In particular, the finding affected the availability, reliability, and capability of the reactor core isolation cooling system, a system that responds to initiating events to prevent undesirable consequences. The finding was of very low safety significance based on the low probability of core damage for the analyzed sequences. (Section 1R14.2)
- Green.
The inspectors identified a finding involving a Non-Cited Violation on Unit 1 for the failure to properly latch the potential transformer fuse drawers for bus 14 and bus 14-1. This resulted in the fuse drawers dropping open and causing the automatic initiation and loading of the emergency diesel generator due to loss of voltage on the emergency bus. Multiple operations department procedures failed to contain instructions to ensure that the potential transformer fuse drawers for the safety-related busses were properly latched. Unit 1 was unknowingly vulnerable to a loss of voltage condition on two safety-related busses during a seismic event.
The finding was more than minor because it was associated with attributes in both the mitigating systems and initiating events cornerstones and also affected each cornerstone objective. For example, a seismic event could cause both drawers to open resulting in a loss of both busses; a scram, and the loss of two residual heat removal service water pumps. The finding was of very low safety significance primarily due to the low initiating event frequency associated with a seismically induced loss of offsite power. (Section 4OA3)
- Green.
The inspectors identified a finding on Unit 2 involving a Non-Cited Violation for the failure to reset the primary containment isolation logic after testing the low pressure coolant injection valves which caused the inoperablility of both residual heat removal loops for more than 18 days.
The inspectors determined that the failure to reset the isolation logic after testing was more than minor because it involved the configuration control, equipment performance, and human performance attributes of the mitigating systems cornerstone, and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding was of very low safety significance based on the operators abilities to recover the system during accident conditions, if required for injection, and the low probability of core damage for the analyzed sequences. (Section 4OA3)
Licensee-Identified Violations
Licensee-Identified Violations
of very low safety significance have been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the corrective action program. These violations and corrective action tracking numbers are listed in Section 4OA7 of this report.
REPORT DETAILS
Summary of Plant Status
Unit 1 began the inspection period operating at maximum achievable power. On January 5 reactor power was reduced to 80 percent for approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to recover two previously inoperable control rods. Reactor power was reduced to 68 percent between January 26 and 27 to perform a control rod pattern adjustment and install a Furmanite clamp on a leaking moisture separator drain tank flange. Toward the end of January, reactor power was reduced to 60 percent to conduct flux suppression testing on a leaking fuel bundle and conduct maintenance of multiple condensate and feedwater pumps. Following the completion of these activities, operators restored Unit 1 to full power on February 4. Additional feedwater, condensate, and reactor recirculation system maintenance, in addition to routine control rod maneuvers, were completed during February 20-24. These activities required a reduction in Unit 1 reactor power to approximately 60 percent. Operators restored Unit 1 to full power on February 25. In addition, on February 28 through March 3, a power reduction to approximately 60 percent was performed to conduct flux suppression testing to identify additional leaking fuel bundles. On March 9, operators restored Unit 1 to full power.
Unit 2 began the inspection period operating at maximum achievable power. On January 2 an operator inadvertently reset the 2A reactor recirculation scoop tube circuitry prior to nulling the potentiometer. This action increased reactor recirculation pump speed and raised reactor power to approximately 101 percent. Operators took immediate actions to reduce pump speed, reactor pressure, and reactor power to normal levels. Following the January 2 transient, Unit 2 operated at normal power levels until January 11, when operators lowered power to 66 percent for feedwater pump maintenance and continued troubleshooting of the 2A moisture separator drain tank level anomalies. Unit 2 returned to full power on January 13. Routine power reductions for turbine valve testing and/or control rod pattern adjustments were conducted on February 7, and the unit was returned to full power conditions the same day.
REACTOR SAFETY
Cornerstone: Initiating Events, Mitigating Systems, and Barrier Integrity
1R04 Equipment Alignment
.1 Partial Walkdowns
a. Inspection Scope
The inspectors performed partial walkdowns of accessible portions of trains of risk-significant mitigating systems equipment during times when the trains were of increased importance due to the redundant trains or other related equipment being unavailable.
The inspectors utilized the valve and electric breaker checklists listed at the end of this report to verify that the components were properly positioned and that support systems were lined up as needed. The inspectors also examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies. The inspectors reviewed outstanding work orders and condition reports associated with the trains to verify that those documents did not reveal issues that could affect train function. The inspectors used the information in the appropriate sections of the Updated Final Safety Analysis Report to determine the functional requirements of the systems.
The inspectors verified the alignment of the following trains:
- 2A Residual Heat Removal Service Water System on February 6, 2003;
- Unit 2 Reactor Core Isolation Cooling System on February 18-20, 2003; and
- Safe Shutdown Makeup Pump on March 11, 2003.
b. Findings
No findings of significance were identified.
.2 Complete Walkdown
a. Inspection Scope
On March 3 through 7, 2003, the inspectors performed a complete system alignment inspection of the instrument air system. This system was selected because it was considered risk-significant in the licensees probabilistic risk assessment. The inspection consisted of the following activities:
- a review of plant procedures (including selected abnormal and emergency procedures), drawings, and the Updated Final Safety Analysis Report to identify proper system alignment;
- a review of outstanding or completed temporary and permanent modifications to the system; and
- an electrical and mechanical walkdown of the system to verify proper alignment, component accessibility, availability, and current condition.
The inspectors also reviewed selected issues documented in condition reports to determine if they had been properly addressed in the licensees corrective actions program. Documents reviewed during this inspection are listed at the end of this report.
b. Findings
No findings of significance were identified.
1R05 Fire Protection
.1 Crib House Walkdown
a. Inspection Scope
The inspectors conducted a walkdown of the crib house basement and ground floor (Fire Zones 11.4.A and B) on January 8, 2003, to ensure that personnel controlled transient combustibles in accordance with procedures. The inspectors observed the condition of fire protection, fire detection, and fire suppression equipment and validated that the equipment was in working condition and free from obstructions. The inspectors reviewed the licensees compliance with previous fire protection program commitments contained in the fire hazards analysis by comparing the commitment information with actual plant configuration. The inspectors also reviewed Condition Report 140803, NRC Has Concern with the Amount of Grease in the Crib House, which was generated as a result of this inspection.
b. Findings
The inspectors identified one Green Non-Cited Violation involving the licensees failure to maintain 80 feet of spatial separation between a flammable liquids storage cabinet and the furthest diesel fire pump as required by the Quad Cities Operating Licenses and the Fire Protection Program.
Prior to inspecting the crib house, the inspectors reviewed the fire protection program commitments for Fire Zone 11.4.B contained in the Quad Cities Fire Hazards Analysis Report. The inspectors noted a commitment to maintain spatial separation between any flammable liquids cabinet and the diesel fire pumps at 25 feet for one pump and 80 feet for the other pump. Administratively, the quantity of materials stored in the cabinets was also limited to less than 25 gallons of oil and less than 10 gallons of grease.
The inspectors and the fire marshall inspected the crib house flammable liquids cabinets contents during the January 8 walkdown. The inspectors determined that the licensee was in compliance with grease and oil storage requirements. Prior compliance was questionable due to the discovery of multiple hand held grease guns and two larger grease guns, each with five gallon containers attached, inside one cabinet. The inspectors verified that neither five gallon container was full. However, the fire marshall stated that maintaining compliance with the grease and oil storage requirements had been a problem previously. The fire marshall initiated Condition Report 140803 to document this issue.
Several days later the inspectors performed an independent inspection of the crib house and determined that the distance between the storage cabinet located on the south side of the crib house and each fire pump may be inadequate. The licensee measured each distance and determined that one of the fire pumps was located within 77 feet of the flammable liquids cabinet.
The inspectors concluded that this finding was more than minor because the improper cabinet placement and storage of a large amount of flammable materials could lead to a fire which could engulf both fire pumps and cause a loss of the non-safety related service water system and the circulating water system. In addition, this finding was associated with the initiating events cornerstone attribute of protecting the plant against external factors and impacted the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions.
The inspectors evaluated this finding using Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process. The inspectors reviewed Inspection Manual Chapter 0609, Appendix F, Figure 4-1, Screening Process Phase 1, and determined that this finding did not affect crib house fire detection and manual suppression capability, automatic suppression capability, or any crib house fire barriers. However, a loss of both fire pumps could impact the automatic suppression capability elsewhere in the plant. Because the fire was postulated to occur in the crib house, a second fire in the plant requiring automatic suppression capability was not assumed. In addition, the inspectors performed fire modeling assuming a wind-free/ventilation-free condition inside the crib house. The inspectors determined that a spill of lubricating oil or grease from the cabinet (resulting in a pool of at least 3.5 feet in diameter) would not produce sufficient radiative heat flux to damage both fire pumps at the same time. Therefore, this finding was characterized as very low risk significant (Green).
Condition 3.F of Quad Cities Operating Licenses DPR-29 and DPR-30 states that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described in the Updated Final Safety Analysis Report for the facility and as approved in the Safety Evaluation Report dated July 27, 1979, with a supplement dated February 12, 1981. The Nuclear Regulatory Commissions Safety Evaluation Report dated February 12, 1981, requires that crib house flammable liquids storage cabinets be installed at least 25 feet and 80 feet away from the two fire pumps respectively to provide spatial separation and preclude a fire in the cabinet from adversely affecting the fire pumps. Contrary to the above, on January 8, 2003, the inspectors determined that the spatial separation between a flammable liquids cabinet and the second fire pump was less than 80 feet. While the failure to maintain adequate spatial separation between the cabinet and a fire pump was a violation, this violation is being treated as a Non-Cited Violation consistent with Section VI.A.1 of the NRCs Enforcement Policy (NCV 50-254/03-03-01; 50-265/03-03-01). This issue was entered into the licensees corrective action program as Condition Report 140803.
.2 Other Quarterly Walkdowns
a. Inspection Scope
During the inspection period, the inspectors conducted in-plant walkdowns of the following risk-significant fire zones to identify any fire protection degradations:
- Fire Zones 8.2.6.A and E, Unit 1 and 2 Turbine Building Ground Floor;
- Fire Zones 11.1.3 and 4, Unit 1 and 2 High Pressure Coolant Injection Room;
- Fire Zone 25.1, Laundry, Tool, and Dry Active Waste Building;
- Fire Zone11.2.1, Unit 1 Reactor Building Southwest Corner Room - 1B Core Spray; and
- Fire Zone 11.2.3, Unit 1 Reactor Building Northwest Corner Room - 1A Core Spray.
During the walkdowns the inspectors verified that transient combustibles were controlled in accordance with the licensees procedures. The inspectors observed the physical condition of fire suppression devices and passive fire protection equipment such as fire doors, barriers, and penetration seals. The inspectors observed the condition and location of fire extinguishers, hoses, and telephones against the Pre-Fire Plan zone maps. The physical condition of passive fire protection features such as fire doors, fire dampers, fire barriers, fire zone penetration seals, and fire retardant structural steel coatings were also inspected to verify proper installation and physical condition. The inspectors also reviewed Condition Report 138737 which was initiated based on the inspection results.
b. Findings
No findings of significance were identified.
.3 Annual Fire Drill Inspection
a. Inspection Scope
On March 18, 2003, the inspectors observed a fire brigade drill on the third floor of the Unit 2 reactor building. This fire drill was chosen due to the fire hazard location and its importance to safety. The inspectors observed that protective clothing was properly donned; self-contained breathing apparatus equipment was properly worn and used; fire hose lines were capable of reaching the necessary fire hazard locations; the fire area was entered in a controlled manner; sufficient fire fighting equipment was brought to the scene; fire brigade leaders fire fighting directions were thorough, clear, and effective; fire fighting pre-planned strategies were utilized; and the licensee pre-planned drill scenario was followed, and the drill objectives acceptance criteria were met.
b. Findings
No findings of significance were identified.
1R07 Heat Sink
a. Inspection Scope
On January 13, 2003, the inspectors observed engineering and operations personnel complete performance testing on the 1A residual heat removal heat exchanger. This heat exchanger was chosen for inspection due to its high safety significance and risk significance. During the testing observation the inspectors verified that the acceptance criteria and test results considered differences between test and design basis conditions because testing at the design heat removal rate was not practical. The inspectors also performed independent calculations using the licensees test results to confirm that the results considered possible uncertainties and that the heat exchanger remained capable of performing its safety function.
b. Findings
No findings of significance were identified.
1R11 Licensed Operator Requalification
a. Inspection Scope
On February 10, 2003, the inspectors observed an operating crew during simulator training on Scenario LOCT-3001-EPU, Raise Power with Recircs, Reactor Feedpump Flow Transmitter Failure, and Loss of Stator Water Cooling.
The inspectors evaluated crew performance in the areas of:
- clarity and formality of communications;
- ability to take timely actions in the safe direction;
- prioritization, interpretation, and verification of alarms;
- procedure use;
- control board manipulations;
- oversight and direction from supervisors; and
- group dynamics.
Crew performance in these areas was compared to licensee management expectations and guidelines as presented in the following documents:
- OP-AA-101-111, Rules and Responsibilities of On-Shift Personnel, Revision 0;
- OP-AA-103-102, Watchstanding Practices, Revision 0;
- OP-AA-103-103, Operation of Plant Equipment, Revision 0;
- OP-AA-103-104, Reactivity Management Controls, Revision 0; and
- OP-AA-104-101, Communications, Revision 0.
The inspectors verified that the crew completed the tasks listed in the above simulator guide. The inspectors also compared simulator configurations with actual control board configurations. For any weaknesses identified, the inspectors observed the licensee evaluators to verify that they also noted the issues and discussed them in the critique at the end of the session.
b. Findings
No findings of significance were identified.
1R12 Maintenance Effectiveness
a. Inspection Scope
The inspectors reviewed the licensees handling of performance issues and the associated implementation of the Maintenance Rule (10 CFR 50.65) to evaluate maintenance effectiveness for the selected systems. The following systems were selected based on being designated as risk significant under the Maintenance Rule, being in increased monitoring (Maintenance Rule category a(1)) group, or due to an inspector identified issue or problem that potentially impacted system work practices, reliability, or common cause failures:
- Unit 1 250 Volt Direct Current Battery Charging System;
- Instrument Air System; and
- Core Spray System.
The inspectors review included examination of the licensees categorization of specific issues, evaluation of the performance criteria, appropriate work practices, identification of common cause errors, extent of condition, and trending of key parameters.
Additionally, the inspectors reviewed the licensees implementation of the maintenance rule requirements, including a review of scoping, goal setting, performance monitoring, short-term and long-term corrective actions, functional failure determinations associated with the condition reports reviewed, and current equipment performance status.
b. Findings
No findings of significance were identified.
1R13 Maintenance Risk and Emergent Work
a. Inspection Scope
The inspectors reviewed the documents listed in the List of Documents Reviewed section of this report to determine if the risk associated with the activities listed below agreed with the results provided by the licensees risk assessment tool. In each case, the inspectors conducted walkdowns to ensure that redundant mitigating systems and/or barrier integrity equipment credited by the licensees risk assessment remained available. When compensatory actions were required, the inspectors conducted plant inspections to validate that the compensatory actions were appropriately implemented.
The inspectors also discussed emergent work activities with the shift manager and work week manager to ensure that these additional activities did not change the risk assessment results.
Maintenance Activities Assessed Date Inspected 1B Residual Heat Removal Heat Exchanger, 1/2 Emergency Week of January 13 Diesel Generator, Unit 2 Station Blackout Diesel Generator, and 2A Residual Heat Removal Heat Exchanger Unit 1 Load Drop to Identify Failed Fuel, 1B and 1C Week of January 31 Feedwater Pump Maintenance, and 1B and 1D Condensate Pump Maintenance 2C Residual Heat Removal Service Water Room Cooler Week of February 3 Tube Bundle Replacement and Maintenance on the Residual Heat Removal System Unit 2 Reactor Water Cleanup and High Pressure Coolant Week of February 17 Injection System Maintenance, Unit 1 Power Reduction for 1B Reactor Recirculation Pump Troubleshooting, Feedwater Pump Maintenance, and Condensate Pump Maintenance Unit 2 Reactor Core Isolation Cooling System Maintenance, Week of March 10 Unit 2B Core Spray Maintenance, 1/2 A Standby Gas Treatment System Maintenance, and Unit 1 Drywell Air Monitors Emergent Maintenance Safe Shutdown Makeup Pump Maintenance, Unit 1A Core Week of March 17 Spray Maintenance, Unit 2A Electrohydraulic Control System Maintenance, and Unit 2 High Pressure Coolant Injection Surveillance Testing
b. Findings
No findings of significance were identified.
1R14 Non-Routine Evolutions
.1 Unit 2 Reactor Power Increase During Reset of 2A Reactor Recirculation Motor
Generator Scoop Tube
a. Inspection Scope
During the week of January 13, 2003, the inspectors reviewed procedures, control room log entries, maintenance work orders, and interviewed licensee personnel to determine the circumstances that led to an inadvertent reset of the 2A reactor recirculation motor generator set scoop tube and a resultant power increase. The inspectors also reviewed Unit 2 thermal limit calculations, Technical Specifications, previous NRC guidance, and the Unit 2 operating license to verify that safety limits were not exceeded and the power increase was not excessive.
b. Findings
No findings of significance were identified.
.2 Unit 2 Reactor Core Isolation Cooling Rendered Inoperable During Scaffold
Disassembly
a. Inspection Scope
During the week of March 23, 2003, the inspectors reviewed procedures and operator log entries, and interviewed licensee personnel to determine the circumstances that led to the inadvertent inoperable condition of the Unit 2 reactor core isolation cooling system. The inspectors also reviewed Technical Specifications, the Updated Final Safety Analysis Report, and relevant station procedures.
b. Inspection Findings The inspectors identified one Green finding involving a human performance error that resulted in the loss of the safety function of the Unit 2 reactor core isolation cooling system.
On March 22, 2003, mechanical maintenance personnel inadvertently bumped the Unit 2 reactor core isolation cooling systems trip throttle linkage causing the trip throttle valve to close. This rendered the reactor core isolation cooling system inoperable. The control room received an annunciator indicating that the trip throttle valve was in the closed position. Operations personnel were dispatched and verified that the trip throttle valve was closed. The inspectors verified that the appropriate Technical Specification was entered and the operating crew initiated the proper tracking report for system inoperability. Later that morning operations personnel reset the trip throttle mechanism and returned the reactor core isolation cooling system to an operable status.
Interviews conducted with mechanical maintenance personnel revealed that the trip throttle mechanism was inadvertently bumped during the removal of scaffold from above the reactor core isolation cooling throttle valve. The scaffold was being disassembled after maintenance activities were conducted on the reactor core isolation cooling system. The inspectors verified that operations personnel appropriately reset the trip throttle valve and returned the system to its standby operational condition. Condition Report 150278 was initiated to document the human performance circumstance and initiate corrective actions to prevent future occurrences.
The inspectors determined that the finding was more than minor because it impacted the mitigating systems attributes and objectives. In particular, the finding affected the availability, reliability, and capability of the reactor core isolation cooling system, a system that responds to initiating events to prevent undesirable consequences.
The inspectors determined that this finding should be evaluated using the Significance Determination Process described in Inspection Manual Chapter 0609, Significance Determination Process, because the finding was associated with the availability, reliability, and capability of a mitigating system. The inspectors conducted a Phase 1 screening and determined that a Phase 2 evaluation was required because the finding represented an actual loss of safety function of a system.
The inspectors used the risk-informed inspection notebook for Quad Cities Nuclear Power Station, Units 1 and 2, Revision 1, dated May 2, 2002, to complete the Phase 2 evaluation. The inspectors determined that the exposure time was less than 3 days.
For each worksheet the inspectors assumed that all mitigating capability was available except for the reactor core isolation cooling system. This resulted in 10 core damage sequences ranging between 9 and 17 points. The most dominate core damage sequences involved:
- (1) the loss of the power conversion system with high pressure coolant injection, safe shutdown makeup pump, and the low pressure injection systems available; and
- (2) a loss of offsite power with the high pressure coolant injection, safe shutdown makeup pump, and the low pressure injection systems available. The inspectors concluded that the final significance determination process result for this finding was 9 points; therefore, the finding was considered to be of very low safety significance (Green) (FIN 50-265/03-03-02).
1R15 Operability Evaluations
a. Inspection Scope
The inspectors assessed the following operability evaluations:
- Operability Evaluation for Condition Report 138067, Heat Tracing on Torus Sample Lines not Sufficient Under Worst Case Accident Conditions, dated January 8 and March 18, 2003;
- Operability Evaluation for Condition Report 140006, Torque Wrench Used to Torque Control Rod Drive Piston Tube Nut Broken During Calibration, dated January 23, 2003;
- Operability Evaluation for Condition Report 139884, A 125 Volt Direct Current Ground Has Been Identified and Isolated to the Unit 2 3E Power Operated Relief Valve Limit Switch (SW1) Circuit, dated January 23, 2003; and
- Operability Evaluation for Condition Report 143666, White Residue Found on 480 Volt Breaker Auxiliary Contacts, dated March 7, 2003.
The inspectors reviewed the technical adequacy of the evaluation against the Technical Specifications, the Updated Final Safety Analysis Report, and other design information; determined whether compensatory measures, if needed, were taken; and determined whether the evaluations were consistent with the requirements of LS-AA-105, Operability Determination Process, Revision 0.
In addition, the inspectors reviewed selected issues that the licensee entered into its corrective action program to verify that identified problems were being entered into the program with the appropriate characterization and significance.
b. Findings
No findings of significance were identified.
1R16 Operator Workarounds
a. Inspection Scope
The inspectors assessed the following operator workaround:
Operator Workaround Reviewed Date 02-017 OC, Safe Shutdown Makeup Pump Cooler Troubles November 26, 2002 The inspectors reviewed the operator workaround to assess any potential effect on the functionality of mitigating systems. The inspectors reviewed the technical adequacy of the licensees workaround documentation against the Updated Final Safety Analysis Report and other design information to assess whether the workaround conflicted with any design basis information. Lastly, the inspectors compared the information in abnormal or emergency operating procedures to the workaround information to ensure that the operators maintained the ability to implement important procedures.
b. Findings
No findings of significance were identified.
1R17 Permanent Plant Modifications
a. Inspection Scope
During the inspection period, the inspectors reviewed the following permanent plant modifications by conducting the activities listed below:
Modification Reviewed Date Design Change Package 340578 - Install Patch Plate Under January 16 Residual Heat Removal Service Water Pipe Support Design Change Package 337160 - Installation of Drain Path February 14 from Unit 1 Station Blackout Diesel Air Compressor Crankcases The inspectors verified that modification preparation, staging, and implementation did not impair the operations departments ability to complete emergency and abnormal operating procedure actions when required, to monitor key safety functions, or to respond to a loss of key safety functions. The inspectors reviewed the design adequacy of the modifications by verifying one or more of the following:
- energy requirements were able to be supplied by supporting systems under accident and event conditions;
- replacement components were compatible with physical interfaces;
- replacement component properties met functional requirements under event and accident conditions;
- replacement components were environmentally and seismically qualified;
- sequence changes remained bounded by the accident analyses and loading on support systems was acceptable;
- structures, systems, and components response times were sufficient to serve accident and event functional requirements assumed by the design analyses;
- control signals were appropriate under accident and event conditions; and
- affected operations procedures were revised and training needs were evaluated in accordance with station administrative procedures.
The inspectors also verified that the post modification testing demonstrated system operability by verifying no unintended system interactions occurred, system performance characteristics met the design basis, and post-modification testing results met all acceptance criteria.

4OA3 Event Follow-up
.1 (Closed) Licensee Event Report 50-254/02-002: Automatic Initiation and Loading of
Emergency Diesel Generator due to Loss of Voltage to Emergency Bus as a Result of Door to Potential Fuse Drawer Falling Open.
On November 13, 2002, maintenance personnel were performing cubicle modifications on safety-related bus 14-1 as part of the Unit 1 refueling outage. The modifications required the individuals to remove the sealing flange between cubicles 8 and 9 by pounding out six rivets using a punch and hammer. As the individuals were removing the second rivet, the force exerted by the punch and hammer on cubicle 9 caused the potential transformer fuse drawer for bus 14-1 to fall open. As the drawer fell open, bus 14-1 experienced a loss of voltage condition which resulted in an automatic start of the Unit 1 emergency diesel generator.
The licensee determined that the drawer fell open because it was not completely latched following previous work activities. The licensee interviewed several operations personnel and determined that the operations department was unaware of the proper methods for securing the drawers and ensuring the drawer was latched. In addition, operations department procedures which manipulated the fuse drawers did not contain instructions for ensuring that the drawers were properly latched. An extent of condition review determined that the bus 14 drawer was also improperly latched.
The inspectors determined that the failure to properly latch the fuse drawers for bus 14 and bus 14-1 was more than minor because this finding was associated with attributes in both the initiating events and mitigating systems cornerstones and also affected each cornerstone objective. For example, a seismic event could have exerted enough force to open both drawers which would have caused the loss of both busses. The loss of bus 14 would have resulted in a reactor scram on low reactor water level due to the loss of two condensate pumps and a subsequent loss of feedwater pumps. The loss of bus 14 would have also caused a loss of one circulating water pump and two residual heat removal service water pumps (mitigating systems equipment). The loss of bus 14-1 would have caused the Unit 1 emergency diesel generator to start. However, the Division II residual heat removal pumps and a core spray pump would not have loaded onto the bus until the undervoltage condition was cleared by reclosing the drawer. Therefore, this mitigating systems equipment would have also been temporarily unavailable.
From a shutdown perspective, this finding was of low risk significance because Unit 1 was not at power and adequate mitigating systems equipment was available to respond to a shutdown event. Because the licensee was unable to determine the actual time the drawers became improperly latched, the inspectors were also required to evaluate this finding using the At Power Significance Determination Process. The inspectors conducted a Phase 1 screening and determined that a Phase 2 evaluation was needed because this finding contributed to both the likelihood of a reactor trip and the likelihood that mitigating equipment or functions would not be available. However, Step 2.5 of Inspection Manual Chapter 0609 stated that the Phase 2 evaluation worksheets did not include external initiating event information. Because of this, a risk analyst was required to perform a Phase 3 evaluation to estimate the increase in risk due to possible external event initiators.
The regional senior reactor analyst determined that this findings risk significance was below the 1E-6 threshold and of very low safety significance (Green) primarily because of the low initiating event frequency associated with a seismically induced loss of offsite power. The analyst concluded that the initiating event of concern would be that activity that could result in the potential fuse drawer falling open (i.e., seismic event). This was found to be consistent with the licensees risk determination, as documented in Licensee Event Report 50-254/02-002.
Criterion V to 10 CFR Part 50, Appendix B, requires that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstance. These instructions, procedures, and drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Contrary to the above, as of November 13, 2002, multiple operations department procedures failed to contain instructions to ensure that the potential transformer fuse drawers for the safety-related busses were properly latched. As a result, the licensee was unknowingly vulnerable to a loss of voltage condition on two safety-related busses during a seismic event. Although the failure to have procedures appropriate to the circumstance was considered a violation of NRC requirements, this violation is being treated as a Non-Cited Violation consistent with Section VI.A.1 of the NRCs Enforcement Policy (NCV 50-254/03-03-03).
This issue was entered into the licensees corrective action program as Condition Report 131373.
.2 (Closed) Licensee Event Report 50-265/03-001: Low Pressure Coolant Injection was
Inoperable for Both Heat Removal Loops Due to Inadequate Procedure Review.
On January 9, 2003, during the completion of QCOS 1000-09, RHR [residual heat removal] Power Operated Valve Test, operations personnel, without operator action, observed the low pressure coolant injection system injection valve 2-1001-29A unexpectedly go to a full-closed position after being stroke-timed open. Troubleshooting identified that relay 10A-K63A was energized causing the valve to automatically close after being opened. This was contrary to the expected deenergized condition. The relay would only be energized if the residual heat removal system were in the shutdown cooling mode of operation and a Group II primary containment isolation signal was received. Also, operating personnel identified that the 10A-K63B relay was in an energized condition. Again, this was not as expected for the existing plant conditions.
As a result, the A and B low pressure coolant injection system injection valves would not open automatically upon initiation of the low pressure coolant injection system injection signal. The proper Technical Specification Limiting Conditions for Operation were entered upon discovery that the residual heat removal low pressure coolant injection mode was inoperable.
The inspectors determined that procedural inadequacies resulting from problem identification and resolution deficiencies contributed to the failure to maintain the residual heat removal low pressure coolant injection system in its proper standby condition. On December 18, 2002, operations personnel performed surveillance QCOS 1600-44, Unit 2 Primary Containment Isolation Group II Partial Isolation Test at Power. During the surveillance, relays 10A-K63A and 10A-K63B were verified to be in an energized state for surveillance completion, however, there was no procedural direction to reset the isolation signal, thereby allowing the relays to remain in an energized state. A similar event was documented in 1995 (Licensee Event Report 265/95-003) that initiated procedural corrective actions. Those corrective actions were not carried forward in subsequent procedure revisions.
The inspectors determined that the failure to adequately reset the isolation signals after testing was more than minor because it: involved the configuration control, equipment performance, and human performance attributes of the mitigating systems cornerstone; and
- (2) affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.
The inspectors determined that this finding should be evaluated using the Significance Determination Process described in Inspection Manual Chapter 0609, Significance Determination Process, because the finding was associated with the availability of a mitigating system. The inspectors conducted a Phase 1 screening and determined that a Phase 2 evaluation was required because the energized state of the relays resulted in an actual loss of the safety function of a system. Also the finding resulted in a loss of a safety function of the system for greater than the Technical Specification Allowed Outage Time.
The inspectors used the risk-informed inspection notebook for Quad Cities Nuclear Power Station, Units 1 and 2, Revision 1, dated May 2, 2002, to complete the Phase 2 evaluation. The inspectors determined that the exposure time was between 3 and 30 days. For each worksheet the inspectors assumed that all mitigating capability was available except for both residual heat removal subsystems. The inspectors allowed credit for recovery because the residual heat removal system could be restored by resetting the primary containment isolation by depressing the containment reset buttons on the control room panel. This resulted in 12 core damage sequences ranging between 10 and 15 points. The most dominate core damage sequences involved:
- (1) the loss of the power conversion system with high pressure injection equipment and core spray system available;
- (2) a medium break loss of coolant accident with the core spray system available;
- (3) a large break loss of coolant accident with the core spray system available; and
- (4) a loss of offsite power with the high pressure injection systems and core spray system available. The inspectors concluded that the final significance determination process result for this finding was 10 points; therefore, this finding was considered to be of very low risk significance (Green).
Criterion V to 10 CFR Part 50, Appendix B, requires that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstance. These instructions, procedures, and drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Contrary to the above, as of May 5, 2000, QCOS 1600-44 failed to contain instructions to ensure that the primary containment isolation logic was reset for residual heat removal low pressure coolant injection system injection valves 2-1001-29A and 2-1001-29B. As a result, from December 18, 2002, until January 9, 2003, the residual heat removal low pressure coolant injection system would not automatically inject as designed if required during certain accident conditions. Although the failure to have procedures appropriate to the circumstance was considered a violation of NRC requirements, this violation is being treated as a Non-Cited Violation consistent with Section VI.A.1 of the NRCs Enforcement Policy (NCV 50-265/03-03-04). This issue was entered into the licensees corrective action program as Condition Report 138696.
3. (Unresolved Item) Failure of ATWS-RPT Breaker to Open as Designed During Plant Shutdown: On July 12, 2002, during the performance of QCOP 0202-34, Unit 2 Reactor Recirculation System Shutdown, the exciter field breaker (ATWS-RPT) failed to open when required. The failure of the breaker to open electronically kept the trip coil in an energized state and resulted in the trip coil burning. An operator responded to the failure and pressed the manual trip button. The operator was unsuccessful in his attempt to trip open the breaker. Finally the operator mechanically agitated the breaker and it immediately went to the open position.
The breaker was removed from its cubicle, quarantined, and transferred to the vendor for further analysis to determine the cause of failure. Based on visual and functional inspections no defects were noted. Also the breaker was mechanically and electrically cycled and the failure could not be repeated.
Further information is needed regarding maintenance practices from the vendor to determine if a maintenance deficiency occurred. Therefore, this is considered to be an Unresolved Item (URI 50-254/03-03-05; 50-265/03-03-05) pending further review of breaker maintenance practices.
4OA6 Meetings
.1 Exit Meeting

- Access Control and Liquid and Gaseous Effluents with Mr. T. Tulon on February 14, 2003.
4OA7 Licensee-Identified Violation
The following violation of very low significance was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section VI of the NRC Enforcement Manual, NUREG-1600, for being dispositioned as a Non-Cited Violation:
Technical Specification 5.5.2 states in part, Integrated leak test requirements for the process sampling system occur at 24 month intervals. Contrary to this requirement, the licensee failed to complete leak test requirements for the high radiation sample system, which is considered the sites process sampling system, at 24 month intervals. The licensee entered the issue into the corrective action program (Condition Report 149403).
The inspectors determined the safety significance of this issue to be of very low safety significance (Green) because upon discovery a leak test was performed and satisfactory results were achieved.
