SUBJECT:

QUAD CITIES NUCLEAR POWER STATION, UNITS 1 AND 2 NRC INTEGRATED INSPECTION REPORT 50-254/02-08; 50-265/02-08

Dear Mr. Skolds:

On December 28, 2002, 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 December 31, 2002, 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 Commission's 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 seven 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 NRC's Enforcement Policy.

If you contest the subject or severity of a Non-Cited Violation, 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 20555-0001, 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 February 25t Order. Phase 1 of TI 2515/148 was completed at all commercial nuclear power JO\ reactors 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 nuclear 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.aov/readina-rm/adams.html (the Public Electronic Reading Room).

Identification and Resolution of Problems, and Event Followup.

This report covers a 3-month period of baseline resident inspection and announced baseline inspections on Temporary Instruction 2515/148, radiation protection, inservice inspection, and emergency preparedness. The inspection was conducted by regional inspectors and the resident inspectors. Three Severity Level IV Non-Cited Violations (NCV) and seven Green Findings were identified. The significance of most findings is indicated by their color (Green,

White, Yellow, Red) using Inspection Manual Chapter 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 NRC's 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-ldentified and Self-Revealing Findings

Cornerstone: Initiating Events

Green.

The failure to identify the proper plant air supply prior to installing moisture separator decontamination equipment (air powered vacuum) resulted in two unexpected instrument air system transients on October 14 and 15, 2002. The work package did not contain equipment identification numbers to aid in identifying the proper air supply. In addition, the individual instructed to identify the air supply failed to perform self-checking activities that could have identified the inappropriate selection of instrument air for the equipment installation rather than service air.

This finding was more than minor because it affected the loss of instrument air initiating event frequency. The finding was of very low safety significance because the exposure time was short and all mitigating systems needed to address a loss of instrument air were available. No violation of NRC requirements occurred due to the instrument air system being non-safety-related. (Section 1R20.1)

Green.

The failure to adequately correct deficiencies in the 1B reactor recirculation motor generator voltage regulator resulted in a pump trip and power transient on December 6, 2002. On November 29 and December 3, the licensee initiated two condition reports due to the motor generator voltage regulator failing to meet acceptance criteria during tuning activities. The inspectors determined that the licensee had not adequately considered changes made to the voltage regulator during the outage and power ascension which resulted in inappropriately concluding that the failure to meet the acceptance criteria was acceptable.

This finding was determined to be more than minor because the reactor recirculation pump trip was a precursor to a significant transient. This finding was considered to be of very low safety significance since it did not: contribute to the likelihood of both a reactor trip and that mitigating equipment would not be available, contribute to the likelihood of a loss of coolant accident, increase the likelihood of a fire or flood, or increase the frequency of core damage scenarios using other plant specific analyses.

(Section 40A2.1)

Cornerstone: Mitigating Systems

Green.

A self-revealing failure occurred on October 16, 2002, when the safe shutdown makeup pump room cooler strainer became clogged with duck weed. The inspectors determined that twice per shift rounds to verify strainer operability and multiple strainer cleanings were not effective in ensuring continued operability of this equipment. In addition, control room personnel were not immediately notified of the clogged strainer via a control room alarm or a local alarm due to a system design deficiency.

This finding was more than minor because the strainer clogging impacted the operability of the safe shutdown makeup pump which can be used when responding to initiating events. In addition, the system design issues created a situation where operations personnel were unaware of equipment operability issues. This finding was of very low safety significance because the total exposure time was short, all other mitigating systems were available, and the safe shutdown makeup pump could have been recovered if needed. No violation of NRC requirements occurred due to the safe shutdown makeup only being of augmented quality per the licensee's Quality Assurance Report. (Section 1R01.2)

Green.

During the 1A stator water heat exchanger tube bundle replacement on November 11, 2002, approximately 200 gallons of water were released as the tube bundle was pulled from the heat exchanger. The water migrated to the Unit 1 emergency diesel generator room below and tripped the circulating oil pump and turbocharger lubricating oil pump rendering the diesel inoperable. The work package used to perform the work did not contain information regarding the large amounts of water that may be present in the heat exchanger. In addition, information regarding the amount of water present in the heat exchanger was not communicated to the contractors performing the work even though this information was well known by operations and maintenance personnel.

This finding was more than minor because the inadequate work instructions and poor communications resulted in a situation which impacted the operability, availability, and reliability of the emergency diesel generator. The finding was of very low safety significance since the loss of the emergency diesel generator did not result in an actual loss of safety function of a system and did not result in an actual loss of safety function of a single train for greater than the Technical Specification Allowed Outage Time. No violations of NRC requirements were identified due to the stator water heat exchanger being non-safety-related. (Section 1R20.2)

Green.

The inspectors identified a Non-Cited Violation of 10 CFR Part 50, Appendix B,

Criterion V, due to the failure to adhere to procedural requirements regarding the erection of scaffolding near safety-related equipment. On November 6, 2002, the inspectors identified numerous examples where scaffolding was in contact with residual heat removal system piping and valves.

This finding was more thari minor since multiple examples of scaffolding erection deficiencies were identified which indicated that workers routinely failed to follow scaffolding erection procedural requirements. This finding was determined to be of very low safety significance since the scaffolding did not result in an actual loss of safety function of any system. (Section 1R20.4)

Green.

A loose wire caused a condition that would have resulted in the failure of the 2B residual heat removal system to automatically start when required and would have resulted in the diversion of water from the 2A residual heat removal system if an emergency core cooling system actuation signal was received while the 2B residual heat removal system was operating in torus cooling. One Non-Cited Violation of Technical Specification 3.5.1 was identified. The licensee determined that the wire was loosened during the February 2002 refueling outage. The impact of the loose wire was not addressed until October 2002 even though unexpected equipment performance was experienced on three previous occasions.

This finding was more than minor since the loose wire impacted the operability, availability, reliability, and capability of the residual heat removal system. The finding was determined to be of very low risk significance since the both trains of the residual heat removal system were recoverable using simple operator actions and all remaining mitigating systems equipment were available. (Section 40A3.2)

Cornerstone: Barrier Integrity

Green.

The failure to adhere to procedure precautions and perform timely control room panel monitoring resulted in the inadvertent isolation of the reactor water cleanup system while the system was being used to remove decay heat from the Unit 1 reactor vessel. A Non-Cited Violation of Technical Specification 5.4.1 was identified.

This finding was determined to be more than minor because the isolation impacted the reactor water cleanup system's continued ability to provide cooling of the reactor fuel and fuel cladding while the Unit 1 reactor was in a shutdown condition. The finding was of very low safety significance since the isolation did not significantly degrade the licensee's ability to recover decay heat removal through the use of the reactor water cleanup or residual heat removal systems once the isolation occurred. (Section 1R20.3)

B. 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 40A7 of this report.

REPORT DETAILS

Summary of Plant Status

Unit 1 began the inspection period operating at reduced power levels due to entering coastdown. On November 5 operations personnel shut down Unit 1 and began a refueling outage. Major activities accomplished during the outage included implementation of an extended power uprate, replacement of the high pressure turbine rotor, modifications to the reactor steam dryer, installation of new condensate demineralizers, and upgrading the high and low pressure feedwater heaters. Unit 1 achieved criticality on November 25 and was synchronized the grid the following day. On December 2 the licensee began power uprate testing. During the multi-day testing evolution, an unisolable leak developed on the 1B reactor feedwater pump. Operations personnel lowered reactor power to 85 percent to complete the leak repairs. On December 6 the operators restored reactor power to 94 percent and began additional power uprate testing. Upon reaching 97 percent power, the 1B reactor recirculation pump tripped due to motor generator set overcurrent on two out of three phases. The pump trip resulted in reducing reactor power to approximately 35 percent. The licensee completed repairs to the reactor recirculation pump on December 9 and continued with the power ascension. Unit 1 achieved and maintained the maximum post-extended power uprate power level on December 11. Engineering and operations personnel completed all required power uprate testing later the same week.

Unit 2 entered the inspection period operating at the maximum achievable power level. On October 7 operations personnel lowered reactor power to approximately 80 percent to repair a leak on the 2A reactor feedwater pump suction relief valve. Unit 2 returned to its maximum power level on October 9. On November 8 and December 5, operations personnel lowered reactor power to approximately 85 percent to conduct turbine valve testing. In both cases the unit was returned to maximum power levels within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

Cornerstone: Initiating Events, Mitigating Systems, and Barrier Integrity

1R01 Adverse Weather Protection (71111

.01 )

.1 Routine Cold Weather Preparations

a.

Inspection Scone From October 29 through November 1, 2002, the inspectors assessed the station's readiness for cold weather conditions by conducting detailed inspections on the ice melt valve and the heat tracing system. The inspectors chose the ice melt valve for inspection due to its importance in preventing the freezing of water for the service water, circulating water, fire water, residual heat removal service water and emergency diesel generator service water systems. The heat tracing system was chosen because of its importance in maintaining the operability of safety-related piping exposed to extreme temperature conditions. The inspectors reviewed the Updated Safety Analysis Report, and seasonal readiness and adverse weather procedures to determine the operational requirements of the ice melt valve and heat tracing systems during cold weather conditions. The inspectors compared this information to the licensee's seasonal readiness open items list, system readiness reports, and open maintenance work requests to ensure that none of the items on these lists impacted the ability of the ice melt valve and heat tracing system to perform their intended functions. The inspectors performed a review of previously initiated condition reports related to cold weather conditions and performed a plant walkdown to ensure that the items documented in the condition reports had been appropriately corrected.

b. Findings

No findings of significance were identified.

.2 Review of Site Specific Weather Condition

a. Inspection Scope

On October 16, 2002, the safe shutdown makeup pump experienced a self-revealing failure when the room cooler service water strainer became fouled with duck weed. The safe shutdown makeup pump system is one of three high pressure systems that can be used to inject water into the reactor during accident conditions. The safe shutdown makeup pump is classified as a risk significant system under the Maintenance Rule and is credited as an injection source in the Appendix R (Fire Protection) Safe Shutdown

Analysis.

Between October 16 and November 5, 2002, the inspectors performed an in-office review of Condition Report 127679, the apparent cause evaluation, operations logs, and procedures associated with the safe shutdown makeup pump to determine past system performance and the reason for the failure. The inspectors interviewed operations, maintenance, and engineering personnel to assess the service water strainer clogging frequency during increased river debris conditions. The inspectors also conducted an inspection of the safe shutdown makeup pump room, including the room cooler and service water systems, to monitor room cooler performance.

b. Findings

The inspectors identified one Green finding due to an inadequate system design which prevented operations personnel from immediately discovering that the safe shutdown makeup pump room cooler service water strainer was clogged with duck weed.

Under normal conditions, operations personnel conducted periodic checks of the safe shutdown makeup pump room cooler service water duplex strainer. When the duplex strainer's differential pressure reached 10 psid or greater, operations personnel were required to swap duplex strainers and notify maintenance to clean the fouled strainer.

During increased river debris conditions, operations personnel were required to check the duplex strainer differential pressure twice per shift.

On October 16, 2002, an operator entered the safe shutdown makeup pump room, noticed that the room seemed warmer than normal, and that the room cooler was not in operation. Since the room cooler was needed to support continued operability of the safe shutdown makeup pump, control room personnel entered Technical Specification 3.7.9. Troubleshooting determined that the safe shutdown makeup pump room cooler was not operating due to the both sides of the service water duplex strainer being fouled.

The inspectors questioned various personnel to determine why operations was not immediately notified of the safe shutdown makeup pump room cooler malfunction via a local or control room alarm. The inspectors were informed that the safe shutdown makeup pump room cooler circuitry was designed without any local or control room alarm functions which could be used to notify personnel of equipment malfunctions. Due to this inadequate design, operations personnel were relying on operator rounds to ensure continued operability of the safe shutdown makeup pump and its associated support equipment.

The inspectors determined that the failure to ensure the safe shutdown makeup pump room cooler circuitry was adequately designed to warn personnel of equipment malfunctions was more than minor because it:

(1) involved the design control and protection against external factors attributes of the mitigating systems cornerstone; and
(2) affected the cornerstone objective of ensuring the operability, availability, reliability, and function of a system that responded to initiating events to prevent undesirable consequences.

The inspectors also determined that this finding should be evaluated using the significance determination process described in Inspection Manual Chapter 0609, "Significance Determination Process." The inspectors conducted a Phase 1 screening and determined that a Phase 2 evaluation was required since the strainer clogging and design inadequacy resulted in 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 since approximately 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> elapsed between the time the room cooler was last verified to be operable and the time the operator discovered the abnormally warm room.

For each significance determination process worksheet completed, the inspectors assumed that all mitigating capability was available except for the safe shutdown makeup pump. The inspectors allowed credit for recovery since the duplex strainer could have been cleaned, and the room cooler re-started, using manual actions. Using these assumptions the inspectors evaluated 22 core damage sequences. Worksheet results ranged from 8 to 18 points. The most dominant core damage sequences involved:

(1) the loss of instrument air with the residual heat removal system available for containment heat removal;
(2) a transient with the loss of the power conversion system and the automatic depressurization system available; and
(3) a loss of service water with the residual heat removal system available for containment heat removal. The inspectors concluded that the final significance determination process result for this finding was 8 points; therefore, this finding was considered to be of very low risk significance (Green)

(FIN 50-254/02-08-01; 50-265/02-08-01). The inadequate design issue did not constitute a violation of NRC requirements since the licensee's quality assurance program considered the safe shutdown makeup pump and its associated support equipment to be of augmented quality. This issue was entered into the licensee's corrective action program as Condition Report 127679.

1R05 Fire Protection

a.

Inspection Scone During the inspection period, the inspectors conducted in-plant walkdowns of the following risk-significant fire zones to identify any fire protection degradations:

  • Fire Zone 8.2.3A Unit 1 Turbine Building Control Rod Drive Pumps;
  • Fire Zone 8.2.6.A, Unit 1 Turbine Building Hallway;
  • Fire Zone 1.1.1.6, Unit Y2 Reactor Building Refuel Floor;
  • Fire Zone 8.2.6.B, Unit 1 Turbine Building Low Pressure Heater Bay;
  • Fire Zone 11.3.3, Unit 2 Reactor Building Northwest Corner Room, Core Spray;

During the walkdowns the inspectors verified that transient combustibles were controlled in accordance with the licensee's 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.

b. Findings

No findings of significance were identified.

1R08 Inservice Inspection Activities

a. Inspection Scone The inspectors conducted a review of the licensee's inservice inspection program for monitoring degradation of the reactor coolant system boundary and the risk significant piping system boundaries. Specifically, the inspectors conducted a record review of the following examinations:

WELD SYSTEM NDE TYPE 23S-S9 High Pressure Coolant Injection Ultrasonic Testing 23S-F4 High Pressure Coolant Injection Ultrasonic Testing 30C-F27 Main Steam Ultrasonic Testing 1OBD-S8 Residual Heat Removal Ultrasonic Testing CRDH Pipe-Pipe Reactor Pressure Vessel Penetrant Testing FW-1 High Pressure Coolant Injection Turbine Radiographic Testing These examinations were evaluated for compliance with the American Society of Mechanical Engineers Boiler and Pressure Vessel Code requirements. The inspectors also reviewed inservice inspection procedures, equipment certifications, personnel certifications, and NIS-2 forms for Code repairs performed during the last outage to confirm that American Society of Mechanical Engineers Code requirements were met.

A sample of inservice inspection related problems documented in the licensee's corrective action program, was also reviewed to assess conformance with 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," requirements. In addition, the inspectors determined that operating experience was correctly assessed for applicability by the inservice inspection group.

b. Findings

The licensee discovered that they had missed inspections of the control rod drive housing welds (Action Report 00113995). Further discussions of this issue with NRC staff was documented in Action Report 00132057. This issue will be an Unresolved Item pending further review of the American Society of Mechanical Engineers Code requirements (URI 50-254/02-08-02; 50-265/02-08-02).

1R11 Licensed Operator Reg ualification

a. Inspection Scope

On October 9, 2002, the inspectors observed an operations crew during a requalification examination on the simulator using Scenario 00-28, 'Torus Narrow Range Instrument Failure, Loss of Coolant Accident Inside Containment, and an Anticipated Transient Without Scram," Revision 10.

The inspectors evaluated crew performance in the areas of:

  • clarity and formality of communications;
  • ability to take timely and conservative actions;
  • 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-1 01 -111, "Rules and Responsibilities of On-Shift Personnel," Revision 0;
  • OP-AA-1 03-103, "Operation of Plant Equipment," Revision 0;

The inspectors verified that the crew completed the critical tasks listed in the above scenario. The inspectors also attended meetings with the licensee's evaluators to ensure that weaknesses noted by the inspectors were noticed by the evaluators and discussed with the crew.

b. Findings

No findings of significance were identified.

1R13 Maintenance Risk Assessments and Emergent Work Evaluation

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 licensee's risk assessment tool. In each case, the inspectors conducted walkdowns to ensure that redundant mitigating systems and/or barrier integrity equipment credited by the licensee's 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 Activity Assessed Week Inspected 125 Volt DC Charger Load Testing December 9, 2002 Risk Associated with Ul High Pressure Coolant Injection Out December 9, 2002 of Service Due to Emergent Work U2 Core Spray Semiannual Logic Test December 9, 2002

b. Findings

No findings of significance were identified.

1R14 Personnel Performance During Non-routine Plant Evolutions

a. Inspection Scope

On October 7, 2002, the inspectors observed control room activities associated with a Unit 2 power reduction to repair a steam leak on a reactor feedwater pump. The inspectors determined by direct observation and a review of procedural requirements that reactivity manipulations were verified by a second licensed operator, that operations personnel were complying with procedures and Technical Specifications, and that plant parameters were as expected for each operating condition.

b. Findings

No findings of significance were identified.

1R15 Operability Evaluations

a. Inspection Scone The inspectors assessed the following operability evaluations or issues associated with equipment operability:

  • Operability Evaluation for Condition Report 124350, "Certain General Electric 480 Volt Breakers not Properly Modeled in ELMS-DC Database," dated September 24, 2002;
  • Discussions Regarding a Lack of Inservice Inspections on Control Rod Drive Housing Welds During October and November 2002 (see Condition Report 132057); and
  • Operability Evaluation for Condition Report 131936, uPotential Failure of Belleville Springs in Main Steam Isolation Valves 2-0203-2B and 2-0203-2C,"

dated November 20, 2002.

The inspectors reviewed the technical adequacy of each 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-1 05, "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 Work-Arounds

Semi-Annual Review

a. Inspection Scope

The inspectors performed a semi-annual review of all operator workarounds and challenges identified as of October 10, 2002. The inspectors assessed the cumulative effects of the workarounds and challenges by performing the following:

  • The inspectors compared workaround and challenge information to the normal, abnormal, and emergency operating procedures to ensure that operations personnel maintained the ability to correctly respond to plant transients in a timely manner;
  • The inspectors utilized system knowledge, a review of plant procedures, and interviews with operations personnel to ensure that the workarounds and challenges previously identified did not adversely impact system reliability and availability, create the potential for system misoperation, or result in a workaround that impacted multiple mitigating equipment; and
  • The inspectors reviewed the equipment status tag log, degraded equipment log, temporary configuration change report, and open operability determination report for potential operator workarounds and challenges that had not been previously identified or assessed for potential impact on normal plant operation or transient response.

In addition to the above, 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.

1R17 Permanent Plant Modifications

a. Inspection Scope

In October and November 2002, the inspectors reviewed the technical adequacy of multiple modifications associated with the Unit 1 extended power uprate. A list of the specific modification packages reviewed is included in the "List of Documents Reviewed" section of this report.

The inspectors verified that modification preparation, staging, and implementation did not impair the operations department's 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 modification by verifying 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.

b. Findings

No findings of significance were identified.

1R19 Post Maintenance Testing

a. Inspection Scope

The inspectors observed and/or reviewed the following post maintenance testing activities during this inspection period:

Post Maintenance Activity Date Inspected Testing Following Modification of the 1A Standby Liquid October 18, 2002 Control Pump Testing Following Replacement of the High Pressure October 24, 2002 Coolant Injection Turning Gear Time Delay Relay For each post maintenance testing activity selected, the inspectors reviewed the Technical Specifications and Updated Final Safety Analysis Report against the maintenance work package to determine the safety function(s) that may have been affected by the maintenance. Following this review, the inspectors verified that the licensee's post maintenance test procedure adequately tested the safety function(s)affected by the maintenance, that the procedure's acceptance criteria were consistent with licensing and design basis information, and that the procedure was properly reviewed and approved. When possible, the inspectors observed the post maintenance testing activity and verified that the structure, system, or component operated as expected; test equipment, when used, was adequately calibrated and within its current calibration cycle; test equipment used was within its required range and accuracy; jumpers and lifted leads were appropriately controlled; test results were accurate, complete, and valid; test equipment was removed after testing; and any problems identified during testing were appropriately documented.

b. Findings

No findings of significance were identified.

1R20 Refueling and Outage Activities

.1 Pre-Outage Work Creates Unexpected Transients in Instrument Air System

a. Inspection Scope

The inspectors interviewed licensee personnel and reviewed work requests, condition reports, and procedures to determine the circumstances which led to two unexpected instrument air transients on October 24 and 25, 2002.

b.

Findinas The inspectors identified one Green finding due to inadequate procedures and the failure to properly self-check prior to connecting temporary plant equipment to plant air systems.

These deficiencies resulted in two separate instrument air system transients.

On October 14, 2002, a chemistry individual assisted a vendor in routing hoses for the moisture separator decontamination project by identifying the water and air connections to be used as directed by Work Order 369947, Task 09. Ten days later, the vendor directed several pipefitters to connect a decontamination skid to the air and water connections previously identified. Later the same afternoon, the vendor began using an air powered vacuum as part of the decontamination activities. Operations personnel immediately noticed abnormal fluctuations in instrument air pressure but were unaware an air powered vacuum was being used in the plant. The operators responded to the pressure fluctuations as required by procedure. However, they were unable to dispatch individuals to the field to search for the cause of the pressure fluctuations prior to the fluctuations stopping.

The next morning vendor personnel began using the same air powered vacuum. At 9:05 a.m., control room personnel received an alarm indicating that the Unit 2 backup service air valve was open. The operators discovered that the Unit 1A and Unit 1/2 instrument air compressors were continuously loaded and instrument air pressures were noted to be cycling between 91 and 98 pounds per square inch. Control room personnel dispatched several non-licensed operators and the field supervisor into the plant to observe air compressor operation and to look for possible air leaks. Operations personnel also started the Unit 2 instrument air compressor to assist in stabilizing the transient.

Approximately 2.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> after noticing the pressure fluctuations, a non-licensed operator discovered the vendor using the air powered vacuum. Additional investigation found that the vacuum had been powered using instrument air rather than service air. The non-licensed operator stopped the decontamination activities and closed the instrument air isolation valve. Instrument air pressures returned to normal.

A subsequent interview of the chemistry individual determined that an inadequate work procedure and improper self-checking contributed to connecting the air powered vacuum to the instrument air system rather than the service air system. Although Work Order 369947, Task 09, contained steps for the chemistry individual to assist in routing the hoses, specific equipment identification numbers were not provided. The chemistry individual stated that when he located the service water connection a Chicago fitting was present on the end of the line to allow the hose to be easily connected to the piping.

When looking for the air connection, the chemistry individual noticed an air valve with a Chicago fitting installed on the end of the piping. The chemistry individual immediately assumed that this was the air supply line to be used during the decontamination project.

Although the valve was properly labeled as an instrument air valve, the chemistry individual failed to check the valve tag.

The inspectors determined that connecting the air powered vacuum to the instrument air system rather than the service air system was more than minor because it:

(1) involved the configuration control attribute of the Initiating Events cornerstone; and
(2) affected the cornerstone objective of limiting the likelihood of those events that upset plant stability during power operations. The inspectors also determined that the error by the chemistry individual affected the cross-cutting area of Human Performance because, despite the inadequate procedure, the valve was properly labeled and self-checking should have been used to ensure that the proper air supply was identified.

The inspectors determined that this finding could be assessed using the significance determination process in accordance with Inspection Manual Chapter 0609, 'Significance Determination Process," because the issue was associated with degraded conditions that could concurrently influence mitigating systems equipment and an initiating event. For the Phase 1 screening, the inspectors answered "yes" to Question 2 under the Initiating Events column which required a Phase 2 evaluation to be performed.

Using the Risk-Informed Inspection Notebook for Quad Cities Nuclear Power Station, Units 1 and 2, Revision 1, dated May 1, 2002, the inspectors determined that the finding's exposure time was less than three days and that the finding increased the likelihood of a loss of instrument air. These assumptions resulted in raising the Table 1 likelihood rating for a loss of instrument air by one decade or to a point value of 3. For the loss of instrument air worksheet, the inspectors determined that all mitigating systems capability was available. This resulted in four core damage sequences between 7 points and 13 points. The most dominant sequence involved the loss of instrument air with containment heat removal and long-term venting available. The inspectors concluded that the final significance determination process result for this finding was 7 points; therefore, this finding was considered to be of very low significance (FIN 50-254/02-08-03; 50-265/02-08-03). No violation of NRC requirements was identified due to the instrument air system being non-safety-related. This issue was placed in the licensee's corrective action program via Condition Report 128977.

.2 Stator Water Heat Exchanger Work Leads to Unit 1 Diesel Inorerabilitv

a. Inspection Scone The inspectors interviewed licensee personnel and reviewed work instructions and condition reports to determine the circumstances which led to the unexpected inoperability of the Unit 1 emergency diesel generator.

b. Findings

The inspectors identified one Green finding due to the use of inadequate stator water heat exchanger work instructions and weak communications which resulted in rendering the Unit 1 emergency diesel generator inoperable.

On November 11, 2002, contractor personnel were performing work to replace the Unit 1A stator water heat exchanger tube bundle. Prior to performing this work, operations personnel had tagged out the heat exchanger for draining purposes. The contractors also established funnels and hoses for collecting the several gallons of water expected to be expelled from the heat exchanger as the tube bundle was removed. As the contractors began removing the tube bundle from the heat exchanger, a large amount of water (as much as 200 gallons) was expelled from the heat exchanger and overwhelmed the funnels and hoses. Within minutes the control room received alarms indicating a problem with the Unit 1 emergency diesel generator. A local operator reported that water from the heat exchanger had migrated into the diesel room and caused the circulating oil pump and the turbocharger lubricating oil pump to trip. Since the operators were unable to fully determine the extent of the water intrusion, the Unit 1 emergency diesel generator was declared inoperable.

Through interviews the inspectors determined that operations personnel were very aware that a large amount of water would be expelled from the stator water heat exchanger when the tube bundle was removed. In fact, the inspectors were informed that this was the reason that the out of service tagout for the stator water heat exchanger was considered an "exceptional" tagout. Operations personnel also told the inspectors that when mechanical maintenance personnel performed a stator water heat exchanger tube bundle replacement a large trough was used to catch the water. The inspectors interviewed the contractor personnel performing the heat exchanger work regarding the information provided by operations. The contractors stated that they were not made aware of the possibility for a large amount of water or that a trough had been used previously to catch the water. The inspectors also reviewed Work Order 99183182, Task 01, "Replace Tube Bundle Assembly in the 1-7401-A Stator Water Heat Exchanger," and found that the work order specifically stated that the heat exchanger would be isolated and drained.

The inspectors determined that the failure to have adequate stator water heat exchanger work instructions, and to communicate information regarding the amount of water, was more than minor because if left uncorrected the inadequate work instructions could continue to impact the availability, reliability, and capability of safety-related equipment.

The inspectors also determined that the failure to ensure adequate work instructions were in place prior to removing the tube bundle also affected the cross-cutting area of Human Performance. Despite multiple individuals being aware that large amounts of water would be expelled during this work activity, actions were not taken to communicate this information to the contractors performing the work.

The Unit 1 emergency diesel generator was normally credited as an emergency power supply for Unit 1 equipment. At Quad Cities the Unit 1 emergency diesel generator was also credited as an emergency power source for common equipment such as the standby gas treatment and control room emergency ventilation systems. When this event occurred, Unit 1 was shut down for a refueling outage. The inspectors reviewed Inspection Manual Chapter 0609, Appendix G, "Shutdown Operations Significance Determination Process," Table 1 for a boiling water reactor in refueling operations with reactor vessel level greater than 23 feet. The inspectors determined that the significance determination process did not apply since the Unit Y emergency diesel generator remained available to address accident situations while Unit 1 was shut down. In regards to Unit 2, the inspectors determined that this issue could be assessed using the At Power Significance Determination Process in accordance with Inspection Manual Chapter 0609, "Significance Determination Process," because the issue was associated with the operability, availability, reliability, or function of a system or train in a mitigating system.

The inspectors performed a Phase 1 screening and determined that this issue was of very low risk significance (Green) since the finding did not represent an actual loss of safety function of a system or an actual loss of safety function of a single train for greater than its Technical Specification Allowed Outage Time (FIN 50-265/02-08-04). No violations of NRC requirements were identified due to the stator water heat exchanger being non-safety related. This issue was included in the licensee's corrective action program as Condition Report 130694.

.3 Untimely Actions Result in Isolation of Decay Heat Removal System

a. Inspection Scope

The inspectors interviewed operations personnel and reviewed condition reports and procedures to determine the circumstances that led to an inadvertent isolation of the reactor water cleanup system while operating in the decay heat removal mode.

b. Findinas This self-revealing event led to the identification of one Green finding and a Non-Cited Violation for the failure to adequately implement QCOP 1200-15, "Operation of Decay Heat Removal Mode of RWCU [Reactor Water Cleanup) System," to ensure that the reactor water cleanup system did not isolate while being used to remove decay heat from the Unit 1 reactor vessel.

On November 24, 2002, operations personnel conducted hydrostatic testing on the Unit 1 reactor vessel. Upon completion of this test, operations personnel continued to remove decay heat from the reactor vessel using the reactor water cleanup system rather than the shutdown cooling mode of the residual heat removal system. At approximately 2:00 p.m., operations personnel made a control room log entry indicating that the reactor water cleanup system high temperature alarm and system isolation setpoints were set at 140 degrees as directed by QCOP 1200-13, "RWCU System High Temperature Isolation Setpoint Adjustment." Nine hours later the reactor water cleanup system isolated while operations personnel were attempting to adjust reactor building closed cooling water system temperature to maintain reactor vessel water temperature within the specified temperature band. Operations personnel were able to restart one of the reactor water cleanup pumps within eight minutes. Heatup of the reactor vessel water was minimal due to the low amount of decay heat present.

The inspectors reviewed QCOP 1200-15 and determined that Step D.2 contained a precaution warning that the reactor water cleanup system would isolate at 140 degrees if the reactor building closed cooling water heat removal capabilities were exceeded. The inspectors determined that operator error and a failure to perform adequate control room panel monitoring resulted in the failure to control reactor building closed cooling water temperature and prevent the reactor water cleanup system isolation. The inspectors determined that this issue was more than minor because it:

(1) involved the human performance attribute of the barrier integrity cornerstone; and
(2) affected the cornerstone objective of providing reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events. The inspectors also determined that the operator's error affected the cross-cutting area of Human Performance.

The inspectors determined that this issue could be assessed using the significance determination process since it 'was associated with maintaining the integrity of fuel cladding. Since Unit 1 was shut down when this event occurred, the inspectors reviewed Inspection Manual Chapter 0609, Appendix G, "Shutdown Operations Significance Determination Process," Table 1 for a boiling water reactor in cold shutdown or refueling operation with a time to boil of greater than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and reactor coolant system level less than 23 feet above the top of the flange. Page T-21 of Table 1 required two residual heat removal shutdown cooling subsystems to be operable with one subsystem in operation.

This statement was being met by operating the reactor water cleanup system in the decay heat removal mode. The inspectors referred to Page T-22 of Table 1 and determined that the inadvertent isolation of the reactor water cleanup system while in the decay heat removal mode of operation was of very low risk significance (Green).

Specifically, the isolation did not significantly degrade the licensee's ability to recover decay heat removal once it was lost since the reactor water cleanup system was easily recoverable and either residual heat removal shutdown cooling subsystem could have been started to remove decay heat.

Technical Specification 5.4.1 requires that written procedures be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Section 3.c of Regulatory Guide 1.33 requires instructions for changing modes of operation for the shutdown cooling system. Contrary to the above, on November 24, 2002, operations personnel failed to properly implement QCOP 1200-15 to prevent a reactor water cleanup system isolation which resulted in changing modes of operation for the shutdown cooling system. This violation is being treated as a Non-Cited Violation consistent with Section VI.A.1 of the NRC's Enforcement Policy (NCV 50-254/02-08-05). This issue was entered into the licensee's corrective action program as Condition Report 133054.

.4 Scaffold In Contact With Plant Equipment

a. Inspection Scope

The inspectors conducted periodic tours of plant facilities and identified multiple examples of outage related scaffolding that was in contact with plant equipment. The inspectors reviewed scaffolding erection procedures to determine if the scaffolding was constructed in accordance with procedural requirements.

b. Findings

The inspectors identified one Green Non-Cited Violation due to the failure to follow procedural requirements regarding the clearances required when erecting scaffolding near the residual heat removal system.

During a walkdown of the residual heat removal system on November 6, 2002, the inspectors identified that scaffolding was in contact with safety-related piping and valves.

The inspectors also identified two other examples of scaffolding erection deficiencies concerning the Unit 1 torus shell and the Unit 1 reactor recirculation motor generator sets.

The inspectors reviewed Procedure MA-AA-796-024, "Scaffold Installation, Inspection, and Removal," Revision 1, and determined that scaffolding inspectors were required to verify that scaffolding was not supported by, in contact with or connected to safety-related equipment. The inspectors notified licensee personnel each time they identified an example of deficient scaffold erection. The inspectors noted that the licensee took timely action to address each scaffold erection issue. However, condition reports were not written for any of the inspector-identified issues. After several discussions regarding scaffold erection deficiencies during the resident inspectors' weekly management debrief, the licensee initiated Condition Report 131690 on November 14, 2002, to document the inspector-identified issues and to determine whether a common cause existed.

The licensee reviewed each scaffolding example and concluded that the equipment impacted remained operable. Therefore, each example was considered minor.

However, in accordance with Inspection Manual Chapter 0612, Appendix B, "Issue Dispositioning Screening," and Appendix E, "Example of Minor Issues," Example 4.a., the inspectors determined that the improper scaffolding erection was more than minor because the number of examples identified demonstrated that workers routinely failed to follow Procedure MA-AA-796-024.

The inspectors determined that this finding could be assessed using the significance determination process. The inspectors determined that this finding was of very low safety significance (Green) since the scaffolding erection deficiencies did not result in a loss of function per Generic Letter 91-18, did not represent an actual loss of safety function of a system, did not represent an actual loss of safety function of a single train for greater than its Technical Specification Allowed Outage Time, did not represent an actual loss of safety function of one or more non-Technical Specification trains of equipment designated as risk significant per 10 CFR Part 50.65 for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and did not screen as potentially risk significant due to a seismic, fire, flooding, or severe weather initiating event.

Criterion V, "Instructions, Procedures, and Drawings," of 10 CFR Part 50, Appendix B, requires that activities affecting quality be performed in accordance with procedures.

Scaffold installation was considered an activity affecting quality and was governed by Procedure MA-AA-796-024. Contrary to the above, on November 6, 2002, the inspectors identified that the licensee failed to implement Procedure MA-AA-796-024 when erecting scaffolding near the residual heat removal system. This violation is being treated as a Non-Cited Violation consistent with Section Vl.A.1 of the NRC Enforcement Policy (NCV 50-254/02-08-06). This issue was entered in the licensee's corrective action program as Condition Report 131690.

.5 General Outage Observations

a. Inspection Scope

The inspectors observed control room activities associated with the shutdown of Unit 1 for a scheduled refueling outage including removing equipment from service, inserting control rods, completing mode specific surveillance testing, and monitoring reactor coolant temperature. The inspectors attended daily outage meetings, reviewed outage control center and control room operator logs, and conducted daily control room tours to ensure that shutdown safety was maintained throughout the outage, reactor coolant system instrumentation provided accurate information, the decay heat removal systems were functioning properly, and inventory and reactivity controls were maintained. The inspectors conducted periodic observations of outage related work activities to ensure that work activities were performed in accordance with plant procedures. The inspectors performed tours of the turbine building, reactor building, and drywell to verify that procedural requirements regarding fire protection, foreign material exclusion, and the storage of equipment near safety-related structures, systems, and components were maintained.

b. Findings

No findings of significance were identified.

1R22 Surveillance Testing

a. Inspection Scope

The inspectors observed surveillance testing activities and/or reviewed completed surveillance test packages for the tests listed below:

0COS 6600-49, "Division 1 ECCS Automatic Actuation Test;"

  • COS 6600-50, "Division 2 ECCS Automatic Actuation Test;" and
  • QOS 6500-03, "Bus 14-1 Undervoltage Test."

The inspectors verified that the structures, systems, and components tested were capable of performing their intended safety function by comparing the surveillance procedure acceptance criteria and results to design basis information contained in Technical Specifications, the Updated Final Safety Analysis Report, and licensee procedures. The inspectors verified that the test was performed as written, the test data was complete and met the requirements of the procedure, and the test equipment range and accuracy was consistent with the application by observing the performance of the surveillance test. Following test completion, the inspectors conducted a walkdown of the test area to verify that the test equipment had been removed and that the system was returned to its normal standby configuration.

b. Findings

No findings of significance were identified.

1R23 Temporary Plant Modifications

a. Inspection Scope

The inspectors reviewed documentation for the following temporary configuration changes:

  • Installation of a temporary pump in the Unit 1 drywell equipment drain sump, and

The inspectors assessed the acceptability of each temporary configuration change by comparing 10 CFR 50.59 screening and evaluation information against the Updated Final Safety Analysis Report and Technical Specifications. The comparisons were performed to ensure that the new configurations remained consistent with design basis information.

The inspectors observed installation and testing of the temporary modifications when applicable; verified that the modifications were installed as directed; the modifications operated as expected; modification testing adequately demonstrated continued system operability, availability, and reliability, and that operation of the modifications did not impact the operability of any interfacing systems. The inspectors also reviewed condition reports initiated during or following temporary modification installation to ensure that problems encountered during installation were appropriately resolved.

b. Findings

No findings of significance were identified.

a. Inspection Scope

The inspectors conducted walkdowns of the radiologically protected area to verify the adequacy of radiation area boundaries and postings including high and locked high radiation areas in the Unit 1 and 2 Reactor Buildings including the Unit I Drywell, and the Turbine Building. Confirmatory radiation measurements were taken to verify that these areas and selected radiation areas were properly posted and controlled in accordance with 10 CFR Part 20, licensee procedures, and Technical Specifications. The inspectors walked down areas having the potential for airborne activity and verified the adequacy of the licensee's continuous air monitoring systems and contamination controls. Selected radiation work permits (RWPs) for radiologically significant work being conducted during the refueling outage (Q1 RI 7) were reviewed for protective clothing requirements and electronic dosimetry alarm set points for both dose rate and accumulated dose.

b. Findinas No findings of significance were identified.

.2 Job-In-Progress Reviews

a. Inspection Scope

The inspectors observed work occurring on the refueling floor including diving and refueling operations. Work progress was observed in the reactor building, drywell, low pressure heater bay and the turbine building. RWP requirements and the As-Low-As-Reasonably-Achievable (ALARA) briefing packages for selected jobs were reviewed to assess their adequacy and to determine if job controls were implemented as intended.

The inspectors determined if dosimetry placement, alarm set points, job site radiological surveys, radiological exposure estimates, contamination controls, airborne monitoring for radioactive materials, and postings were adequate given the jobs' radiological conditions.

b. Findings

No findings of significance were identified.

20S2 ALARA Planning and Controls (71121.02)

.1 Inspection Planning

a. Inspection Scope

The inspectors reviewed the plant's exposure history and trends, its three year rolling average dose and the impact of source term on radiological exposure under outage conditions, in order to assess radiological challenges for the current outage. The licensee's processes to estimate and track radiological exposure were discussed with radiation protection management to determine if the licensee's practices were appropriate.

b. Findings

No findings of significance were identified.

.2 Radiological Work Planning

a. Inspection Scope

The inspectors reviewed the station's processes for radiological work planning and scheduling, and evaluated the dose projection methodologies and practices implemented for the Q1 R1 7 refueling outage, to verify that the technical bases for outage dose estimates were adequate. Specifically, the inspectors reviewed radiologically significant RWP/ALARA planning packages to verify that person-hour estimates, job history files, lessons learned, and industry experiences were utilized in the ALARA planning process.

The inspectors also reviewed total effective dose equivalent ALARA evaluations to assess the licensee's analysis of evolutions involving potential airborne activity for the use of respiratory protection equipment. The inspectors also attended ALARA committee meetings and shift turnovers to further assess inter-departmental coordination and ownership in the-radiological work/ALARA planning and scheduling processes.

b. Findings

No findings of significance were identified.

.3 Job Site Inspection and ALARA Control

a. Inspection Scope

The inspectors reviewed jobs being performed in areas of elevated dose rates, examined exposure estimates and work sites, and evaluated selected RWP's along with the associated ALARA briefing packages to verify that worker radiological exposure was minimized. Protective clothing requirements, dosimeter use including radiotelemetry dosimetry, and electronic dosimeter alarm set points were evaluated for consistency with RWP packages. The use of engineering controls were also reviewed to verify that worker exposures were maintained ALARA.

The inspectors attended selected pre-job ALARA and work control briefings, and observed portions of work evolutions directly and by using the licensee's remote closed circuit monitoring system in order to verify that adequate work controls were in place to maintain worker exposures ALARA. During job site walkdowns, radworkers and supervisors were observed to determine if low dose waiting areas were being used appropriately, and to evaluate the effectiveness of job supervision including equipment staging, use of shielding, availability of tools, and work crew size.

b. Findings

No findings of significance were identified.

.4 Radiation Dose Estimates and Exposure Tracking Systems

a. Inspection Scope

b. Findings

No findings of significance were identified.

.5 Identification and Resolution of Problems

a. Inspection Scope

The inspectors evaluated the effectiveness of the station's problem identification and resolution processes to identify, characterize and prioritize problems, and to develop and implement corrective actions. The evaluation included review of:

(1) the results of a focus area self-assessment of the ALARA Planning and Control Program performed during 2002;
(2) a Nuclear Oversight continuous assessment report along with field observation reports of the radiation protection program (access control and ALARA programs) that were completed in calendar years 2001 and 2002; and
(3) the licensee's condition report (CR) database and individual CRs related to the access control and ALARA programs for years 2001 and 2002.

The licensee's corrective action program for radiation protection issues was evaluated to verify that problems were appropriately prioritized and resolved in a timely manner, commensurate with their importance based on safety and risk. This evaluation included procedure and documentation reviews, discussions of the program with cognizant licensee personnel, and observing management meetings in which CRs were evaluated.

2PS2 Radioactive Material Processing and Transportation (71122.02)

.1 Walkdown of Radioactive Waste Systems

a. Inspection Scope

The inspectors reviewed the liquid and solid radioactive waste system description in the Final Safety Analysis Report and the most recent information regarding the types and amounts of radioactive waste generated and disposed. The inspectors performed walkdowns of the liquid and solid radwaste processing systems to verify that the systems agreed with the descriptions in the Final Safety Analysis Report and the Process Control Program, and to assess the material condition and operability of the systems. The inspectors reviewed the current processes for transferring waste resins into shipping containers to determine if appropriate waste stream mixing and/or sampling procedures were utilized. The inspectors also reviewed the methodologies for waste concentration averaging to determine if representative samples of the waste product were provided for the purposes of waste classification in 10 CFR 61.55. During this inspection, the licensee was not conducting waste processing.

b. Findings

No findings of significance were identified.

.2 Waste Characterization and Classification

a. Inspection Scope

The reviews were conducted to verify that the licensee's program assured compliance with 10 CFR 61.55 and 10 CFR 61.56, as required by Appendix G of 10 CFR Part 20. The inspectors also reviewed the licensee's waste characterization and classification program to ensure that the waste stream composition data accounted for changing operational parameters and thus remained valid between the annual sample analysis updates.

b. Findings

No findings of significance were identified.

.3 Shipment Preparation

a. Inspection Scope

Since there were no radioactive materials shipped from the site during the inspection, the inspectors reviewed the records of training provided to personnel responsible for the conduct of radioactive waste processing and radioactive shipment preparation activities.

40A2 Identification and Resolution of Problems (71152)

.1 1B Reactor Recirculation Pump Trips on Overcurrent Condition

a. Inspection Scope

The inspectors assessed the circumstances surrounding the 1B reactor recirculation pump trip by interviewing site personnel and reviewing condition reports. The inspectors also reviewed the 1B reactor recirculation pump maintenance work history to determine if the current pump trip was similar to previous trips.

b. Findings

The inspectors identified one Green finding due to the failure to correct previously identified deficiencies with the 1B reactor recirculation motor generator voltage regulator.

On December 6, 2002, the 1B reactor recirculation pump tripped on an overcurrent condition. The licensee determined that voltage regulator instabilities caused by a lack of adequate capacitance in the regulator circuitry caused the pump trip. The inspectors reviewed Condition Reports 133549 and 133856 initiated on November 29 and December 3, 2002, respectively. The inspectors determined that both of the condition reports were written because the 1B reactor recirculation motor generator set failed to meet the acceptance criteria specified in Procedure MA-AB-772-301 during voltage regulator tuning activities.

The licensee evaluated the information in both condition; reports and determined that continued operation of the 1B reactor recirculation pump was acceptable since the voltage regulator performance was similar to the performance experienced from February to November 2002. The licensee planned to add additional capacitance to the voltage regulator circuitry at a later date. The inspectors reviewed the licensee's decision to continue operating the 1B reactor recirculation pump and determined that previous and current operating conditions had changed. During the Unit 1 refueling outage, the licensee adjusted the voltage regulator stability and gain potentiometers on numerous occasions. However, it did not appear that the licensee adequately considered these subtle differences in performance prior to continuing operation.

The inspectors reviewed the 1B reactor recirculation pump maintenance work history and discovered that the pump had tripped twice in November 2000. The licensee's investigation determined that the pump trips occurred due to equipment failures and a lack of understanding for how the voltage regulator functioned. Corrective actions to prevent recurrence included component replacements and voltage regulator performance training. Based on the 1B reactor recirculation pump trip of December 6, 2002, the inspectors determined that the licensee's corrective actions to prevent recurrence were ineffective.

The failure to adequately address the 1B reactor recirculation motor generator voltage regulator failures was more than minor because the resulting pump trips could be reasonably viewed as a precursor to a significant event. The inspectors determined that this finding could be assessed using the significance determination process for the same reason. The inspectors conducted a Phase 1 screening and determined that this finding was of very low safety significance (Green) because it did not:

(1) contribute to the likelihood of a primary or secondary system loss of coolant accident initiator;
(2) contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available;
(3) increase the likelihood of a fire or internaVexternal flood; or
(4) increase the frequency of core damage scenarios of concern using the Individual Plant Examination for External Events or other plant specific analyses (FIN 50-254/02-08-07). This issue was not subject to NRC enforcement since the reactor recirculation pump and the motor generator voltage regulator are non-safety-related components.

After the December 6, 2002, pump trip the licensee added approximately 500 microfarads of capacitance to the voltage regulator circuit and established an administrative limit which prevented operating the 1B reactor recirculation pump at greater than 92 percent speed. The licensee planned to install additional circuit capacitance on approximately January 6, 2003.

.2 Routine Review of Identification and Resolution of Problems

a. Inspection Scope

As discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensee's corrective action system at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. Issues entered into the licensee's corrective action system as a result of inspectors' observations are generally denoted within the body of the report. Specific issues related to routine problem identification and resolution were discussed in Sections 1R20.4, 40A2.1, and 4OA3.2 of this report.

b. Findings

No findings of significance were identified.

40A3 Event Follow-up (71153)

.1 (Closed) Licensee Event Report 50-265102-004: Inadequate Separation in Both Trip

Systems of the Scram Discharge Instrument Volume Input to the Reactor Protection System.

On August 2, 2002, the licensee determined that an engineering change (EC 24572),implemented in March 2002 resulted in the failure to maintain electrical separation between the safety-related reactor protection system cabling and the non-safety-related plant computer. Upon discovery the licensee entered Technical Specification 3.3.1.1, Condition B, which allowed 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> to place the reactor protection system in a tripped condition. The licensee installed a temporary modification within the 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> which disabled the scram discharge volume input to the plant computer.

The licensee failed to identify this electrical separation issue earlier due to a lack of rigor during the modification review process. The inspectors determined that this issue was minor since one channel in each reactor protection trip system remained operable. In the event that there had been an actual scram discharge volume high level condition, concurrent with the plant computer cabling and the reactor protection system wiring shorting together, the scram function would still have been initiated.

.2 (Closed) Licensee Event Report 50-265/02-005: Failure of Low Pressure Coolant

Injection Logic Test due to Detached Wire.

During logic testing on the 2B residual heat removal subsystem on October 7, 2002, operations personnel were unable to complete a step in QCOS 1000-44, "Unit 2 B Loop Low Pressure Coolant Injection and Containment Cooling Modes of Residual Heat Removal Non-Outage Logic Test." Troubleshooting identified an unlanded wire that should have been connected to fuse holder FF-F1 I within the residual heat removal logic circuitry. The licensee determined that the failure of the wire to be connected to the fuse holder resulted in the 2B residual heat removal subsystem being unable to automatically start in response to an emergency core cooling system initiation signal. The licensee also found that if the 2B residual heat removal subsystem was operating in torus spray or torus cooling certain valves would not have automatically closed upon the receipt of an emergency core cooling system initiation signal. As a result, low pressure injection from the 2A residual heat removal subsystem would have been diverted from the reactor vessel to the torus through the open torus cooling and/or torus spray valves until the operators manually closed the valves.

The inspectors determined that human performance and problem identification and resolution deficiencies contributed to the failure to identify and correct the residual heat removal wiring issue. On February 18, 2002, maintenance personnel performed activities inside the electrical panel containing fuse block FF-F1 1. The maintenance work conducted required fuse block FF-F1 1 to be moved; no wires were de-terminated from the fuse block. Following the electrical panel maintenance, personnel re-installed fuse block FF-F1 1 but did not visually or physically verify the integrity of any wiring connections. Testing following the maintenance demonstrated that the wiring connected to fuse block FF-F1 1 was in contact with the fuse block. However, the licensee believes the wiring was loose. Instrument maintenance personnel conducted several surveillances between March 18 and October 7, 2002, with unexpected results. Although actions were taken to document the unexpected results, the rigor in evaluating these results was less than adequate since equipment operability was not addressed.

On March 1, 2002, operations personnel completed QOCOS 6600-48, "Unit 2 Division 2 Emergency Core Cooling System Simulated Automatic Actuation and Diesel Generator Auto-Start Surveillance." The test completion demonstrated that the wires associated with fuse block FF-F1 1 remained in contact with the fuse block. Approximately 2.5 weeks later, instrument maintenance personnel conducted OCIS 1000-13, "High Drywell Pressure Core Spray, Low Pressure Coolant Injection, and Emergency Diesel Generator Calibration and Functional Test." During this test the instrument technicians noticed that the residual heat removal lights for high drywell pressure did not illuminate as expected. One light flickered and extinguished; the other light never illuminated.

Since the light illumination was not part of the QCIS 1000-13 acceptance criteria, the instrument technicians noted their observation and generated Work Order 421277 to investigate the light failure. Troubleshooting by the fix-it-now team determined that the light failures were not caused by burnt out bulbs. No other actions were taken to explain the significance or cause of the light failure. Instead Work Order 421277 was re-scheduled for completion during the May 2002 residual heat removal work week window. Prior to May 2002, Work Order 421277 was re-classified as outage work for unknown reasons. The inspectors noted that the next Unit 2 refueling outage was not scheduled until 2004. During performances of QCIS 1000-13 on June 13 and September 6, 2002, the instrument technicians continued to document the failure of the residual heat removal lights for high drywell pressure to illuminate. No actions were taken following the subsequent performances of QCIS 1000-13 due to the licensee's belief that the lights were for indication only.

The inspectors determined that the failure to adequately address the impact of the extinguished lights were more than minor because it:

(1) 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 also 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 since the disconnected wire resulted in an actual loss of safety function of a single train for greater than the Technical Specification Allowed Outage Time. This finding also resulted in an actual loss of safety function of the residual heat removal system during times when the 2B system was operating in the torus cooling or torus spray modes.

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 greater than 30 days which increased the initiating event likelihood for all initiating events by two orders of magnitude. 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 since the residual heat removal system could be aligned for low pressure injection through manual operator actions. This resulted in 11 core damage sequences between 9 and 14 points. The most dominant core damage sequences involved:

(1) the loss of the power conversion system with high pressure injection equipment and the core spray system available;
(2) a large break loss of coolant accident with the core spray system available; and
(3) a loss of offsite power with the high pressure injection systems and the core spray system available. The inspectors concluded that the final significance determination process result for this finding was 9 points; therefore, this finding was considered to be of very low risk significance (Green).

Technical Specification 3.5.1, "Emergency Core Cooling System - Operating," requires that each emergency core cooling system injection and/or spray subsystem be operable in Modes 1, 2, and 3. Technical Specification 3.5.1, Condition B, allows one residual heat removal subsystem to be inoperable for up to 7 days. Condition C of the same Technical Specification allows both residual heat removal subsystems to be inoperable for up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The inspectors determined that as of March 18, 2002, the 2B residual heat removal subsystem, an emergency core cooling system, was inoperable. In addition, both residual heat removal subsystems were inoperable at various times between March 18 and October 7, 2002. This determination was based upon the fact that as of March 18 the licensee was no longer able to ensure that the wire was adequately secured to fuse block FF-F1 1. The failure to have both residual heat removal subsystems operable while operating in Modes 1, 2, and 3 was considered a Non-Cited Violation of Technical Specification 3.5.1 in accordance with Section VI.A.1 of the NRC's Enforcement Policy (NCV 50-265/02-08-08). This issue was entered into the licensee's corrective action program as Condition Report 126235.

.4 Unit I in Single LooD Operation Due to 1B Reactor Recirculation Pump Trip

On December 6, 2002, the inspectors reviewed the circumstances surrounding the 1B reactor recirculation pump trip. The inspectors reviewed the timeliness and adequacy of operator actions during the transient condition. The inspectors determined that the operators reacted appropriately and followed procedural requirements during the transient condition. The inspectors also determined through observation that the operators appropriately implemented procedures to allow the unit to operate in single loop operations during the troubleshooting and reactor recirculation pump restoration activities. Further information regarding the incident is described in Section 40A2 of this report.

40A4 Cross-Cutting Findings

.1 Human Performance Related Findings

Findings described in Sections 1R20.1, 1R20.2, 1R20.3, and 40A3.2 of this report had one or more human performance deficiencies which caused the event to occur. An individual failed to use self-check techniques when identifying the proper plant air supply for an air powered vacuum. This error resulted in two separate instrument air transients on October 24 and 25, 2002 (see Section 1R20.1).

A communications weakness between operations, maintenance and contractor personnel resulted in a large amount of water being expelled from a stator water heat exchanger during maintenance. The water migrated to the room below and resulted in the Unit 1 emergency diesel generator being declared inoperable (see Section 1R20.2).

Failure to follow procedures and untimely control room panel monitoring led to the unexpected isolation of the reactor water cleanup system while the system was being used to remove decay heat during the Unit 1 refueling outage (see Section 1R20.3).

Lastly, the failure to verify the physical integrity of wiring connections following maintenance activities led to a condition which resulted in the 2B residual heat removal system being inoperable for more than 6 months (see Section 40A3.2).

.2 Problem Identification and Resolution Related Findings

The licensee did not initiate condition reports following the inspectors identification of multiple scaffolding erection deficiencies (see Section 1R20.4). As a result, additional scaffolding deficiencies were identified by other plant personnel. Later in the inspection period, the licensee initiated a condition report encompassing all of the inspector identified scaffolding issues. Once this action was taken, the licensee began conducting an evaluation to determine whether a common cause had contributed to some or all of the identified deficiencies.

Weaknesses in problem evaluation resulted in the failure to correct deficiencies with the 1B reactor recirculation voltage regulator (see Section 40A2.1). On November 29 and December 3, 2002, the licensee initiated two condition reports due to the I B reactor recirculation pump voltage regulator failing to meet proceduralized acceptance criteria.

During the evaluation of these condition reports, the licensee did not fully consider changes made to the voltage regulator during the outage and power ascension. These actions resulted in Unit 1 being at an increased risk for a plant transient and a subsequent reactor recirculation pump trip on December 6, 2002.

Deficiencies in problem evaluation and prioritization also led to the failure to recognize that the 2B residual heat removal system was inoperable (see Section 40A3.2). The inspectors determined that licensee personnel had at least three prior opportunities to identify this condition prior to discovery of the condition on October 7, 2002. These opportunities were not acted upon due to the licensee's belief that an extinguished light was for indication only rather than a sign of equipment malfunction.

4OA5 Other Activities

.1 Completion of Appendix A to TI 2515/148. Revision 1

The inspectors completed the pre-inspection audit for interim compensatory measures at nuclear power plants, dated September 13, 2002.

.2 Power Uprate

a. Inspection Scone The inspectors observed control room activities associated with the Unit 1 power uprate including power ascension testing and surveillance testing. The inspectors also reviewed daily licensee power uprate observations and evaluations to ensure deficiencies were adequately evaluated. The inspectors performed tours of the turbine building and reactor building to assess plant conditions as power ascension activities progressed. The inspectors reviewed plant modification plans and post-modification testing.

b. Findings

No findings of significance were identified.

40A6 Meetings

.1 Exit Meeting

The inspectors presented the inspection results to Mr. T. Tulon and other members of licensee management at the conclusion of the inspection on December 31, 2002. The inspectors asked the licensee whether any materials examined during the inspection should be considered proprietary. No proprietary information was identified.

.2 Interim Exit Meetings

Interim exits were conducted for:

  • Access Control, ALARA Planning and Control, and Radwaste and Transportation with Mr. T. Tulon on November 15, 2002.

Inservice Inspection with Mr. T. Tulon on November 21, 2002.

40A7 Licensee-Identified Violations The following violations of very low significance were identified by the licensee and are violations of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Manual, NUREG-1 600, for being dispositioned as Non-Cited Violations.

Cornerstone: Mitigating Systems

Technical Specification Surveillance Requirement 3.8.4.7 requires that the licensee verify that battery capacity is adequate to supply, and maintain in an operable status, the required emergency loads for the design duty cycle every 24 months. As described in Condition Report 124350, on September 24, 2002, the licensee had not included charging spring motor loads for certain General Electric 480 Volt breakers as part of the design duty cycle during previous battery testing. As a result, the license had not adequately performed the surveillance testing required by Technical Specification Surveillance Requirement 3.8.4.7.

The licensee entered Technical Specification Surveillance Requirement 3.0.3 in response to the missed surveillance test. This surveillance requirement allowed the licensee to delay entry into Technical Specification 3.8.7 due to the discovery of missed surveillances as long as the a risk evaluation was performed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and the missed surveillance tests were completed within the Technical Specification specified frequency (in this case 24 months). The inspectors reviewed the licensee's risk assessment and determined that the risk to the plant from the missed surveillances was very low since calculations showed that adequate battery capacity was available to supply all required loads. Subsequent testing of the Unit 1 and 2 batteries also demonstrated that adequate capacity was available to supply the required loads.
