SUBJECT:

KEWAUNEE NUCLEAR POWER PLANT NRC INTEGRATED INSPECTION REPORT 50-305/03-04

Dear Mr. Coutu:

On June 30, 2003, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Kewaunee Nuclear Power Plant. The enclosed integrated inspection report documents the inspection findings, which were discussed on July 2, 2003, with you and 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, there was one NRC-identified and three self-revealed findings of very low safety significance (Green). These findings were determined to involve violations of NRC requirements. However, because these violations were non-willful and non-repetitive and because they were entered into your corrective action program, the NRC is treating this findings as Non-Cited Violations, in accordance with Section VI.A.1 of the NRCs 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 Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies 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 NRC Resident Inspector at the Kewaunee facility. Since the terrorist attacks on September 11, 2001, NRC has issued five Orders and several threat advisories to licensees of commercial power reactors to strengthen licensee capabilities, improve security force readiness, and enhance controls over access authorization. In addition to applicable baseline inspections, the NRC issued Temporary Instruction 2515/148, "Inspection of Nuclear Reactor Safeguards Interim Compensatory Measures," and its subsequent revision, to audit and inspect licensee implementation of the interim compensatory measures required by order. Phase 1 of TI 2515/148 was completed at all commercial nuclear power plants during calender year 2002 and the remaining inspection activities for Kewaunee are scheduled for completion in November 2003. The NRC will continue to monitor overall safeguards and security controls at the Kewaunee Nuclear Power Plant.

In accordance with 10 CFR 2.790 of the NRCs Rules of Practice, a copy of this letter and its enclosure will be made available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs 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).

Sincerely,

SUMMARY OF FINDINGS

IR 05000305-03-04; 04/01/2003 - 06/30/2003; Kewaunee Nuclear Power Plant; Refueling and

Outage Activities; Fitness-for-Duty Program This report covers a 3-month period of baseline resident inspection and announced baseline inspections for radiation protection, inservice inspection and Temporary Instruction (TI)2515/150, and physical protection. The inspections were conducted by the resident inspectors, and Region III inspectors. One NRC identified and three self-revealed Green findings associated with non-cited violations (NCVs) were identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609,

Significance Determination Process. Findings for which the Significance Determination Process 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.

NRC-Identified

and Self-revealed Findings

Cornerstone: Initiating Events

Green.

A self-revealed, non-cited violation of 10 CFR 50, Appendix B, Criterion V, was identified for the licensees failure to properly sequence a tagout in accordance with the licensees tagout procedure. This resulted in an approximate 100-gallon loss of inventory from the reactor coolant system. A contributing cause of this finding was related to the cross-cutting area of Human Performance.

This finding is greater than minor because it affected the Initiating Events Cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations.

The finding is of very low risk significance because none of the checklist attributes of Inspection Manual Chapter 0609, Shutdown Operations Significance Determination Process, Appendix G, were affected. (Section 1R20.3)

Green.

A self-revealed, non-cited violation of 10 CFR 50, Appendix B, Criterion V, was identified for the licensees failure to ensure that the procedure governing refueling operations and reactor head disassembly had appropriate instructions or cautions to ensure that the reactor head vent remained vented to containment atmosphere. This resulted in the reactor head vent not being vented and affecting the operation of the refueling cavity water level instrument which operators were using to control reactor vessel water level.

This finding is greater than minor because it is a configuration control issue which affected the Initiating Events Cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The finding is of very low risk significance because none of the checklist attributes of Inspection Manual Chapter 0609,

Shutdown Operations Significance Determination Process, Appendix G, were affected. (Section 1R20.4)

Cornerstone: Mitigating Systems

Green.

A self-revealed non-cited violation 10 CFR 50, Appendix B, Criterion V, was identified for the licensees failure to ensure that the residual heat removal pump recirculation piping material was in accordance with a facility drawing and engineering specifications. This resulted in the corrosion of three pipe plugs, one of which was corroded to the point of leaking. The pipe plugs were installed on each residual heat removals recirculation pipe pressure breakdown orifice. The three pipe plugs were made of carbon steel while the residual heat removal system piping, which contained borated water, was required to be made of stainless steel.

This finding was greater than minor because it affected the Mitigating System Cornerstone objective of equipment reliability and availability, in that the failure to ensure that the residual heat removal piping materials are in accordance with plant engineering specifications and drawings could result in system leakage significant enough to require taking the system out-of-service. The finding is of very low risk significance because this finding was not a design or qualification deficiency which resulted in a loss of function per Generic Letter 91-18. (Section 1R20.2)

Cornerstone: Physical Protection

Green.

A finding of very low safety significance was identified by the inspectors for a violation of 10 CFR Part 26 Fitness-for-Duty (FFD) reporting requirements. The licensee failed to notify the NRC Operation Center within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of discovery of an illegal drug found within the licensees protected area. The licensee failed to report the event because they did not realize this type of event was required to be reported.

The finding was determined to be of very low significance because it was a vulnerability in the licensees Safeguards plan, was not a malevolent act, and similar findings had not occurred in the last four calendar quarters. The finding was determined to be more than minor because illegal drugs located within a licensees protected area are required to be reported to the NRC in accordance with 10 CFR 26.73(a) requirements. (Section 4OA3)

Licensee-Identified Violations

None.

REPORT DETAILS

Summary of Plant Status

The plant was operated at approximately 100 percent power until April 5, 2003, when the plant was shutdown to commence the 2003 refueling outage. The plant was started and returned online on May 11, and achieved 100 percent power on May 18. The plant was operated at approximately 100 percent power for the remainder of the inspection period.

REACTOR SAFETY

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity

1R01 Adverse Weather Protection

.1 Technical Support Center (TSC) Diesel Generator (DG)

a. Inspection Scope

The licensee has credited the TSC DG as the alternate alternating current DG for station blackout mitigation, the inspectors reviewed the TSC DG for its susceptibility to hot weather conditions and high winds. On May 16, 2003, the inspectors walked down the TSC DG and the associated support equipment to verify that the material condition of the equipment was acceptable. The inspectors reviewed the licensees operating procedures, including Procedure RT-DGM-10-TSC, Technical Support Center Diesel Generator, Revision W, to ensure the procedures prescribed appropriate instructions for proper operation of the TSC DG.

The inspectors also reviewed the Updated Safety Analysis Report, Section 8.2.4, Station Blackout, Revision 17, to verify that the design requirements of the TSC DG would be met under adverse weather conditions. Additionally, the inspectors reviewed the TSC DG vendor manual, Western Engine Co. Model: TSC Diesel Generator, Revision 0, to determine whether there were any operational or design requirements associated with hot weather that were not already incorporated into the licensees procedures.

b. Findings

No findings of significance were identified.

.2 Substation Switchyard Walkdown

a. Inspection Scope

On May 30, 2003, the inspectors walked down the site substation switchyard to determine whether the area was maintained and ready for seasonal adverse weather conditions which include potentially high winds and tornados. Initiating events involving a loss of offsite power contributed up to 55 percent of the facilitys core damage frequency, and therefore the substation switchyard was considered to be a potential risk significant area. The inspectors evaluated the housekeeping of the area, interviewed electrical maintenance personnel, and a reviewed the Updated Safety Analysis Report.

b. Findings

No findings of significance were identified.

1R04 Equipment Alignment

a. Inspection Scope

Partial System Walkdowns The inspectors performed three partial system walkdowns during this inspection period.

On April 11, 2003, the inspectors walked down the B train DG, reserve auxiliary transformer, tertiary auxiliary transformer, and substation while the A train DG was out-of-service for the refueling outage overhaul. On May 22, 2003, the inspectors walked down the A component cooling water train and associated support equipment while the B component cooling water train was out-of-service for a scheduled surveillance test. On June 13, 2003, the inspectors walked down the Control Room Post-Accident Recirculation System following realignment of the system after testing which was performed for troubleshooting.

To evaluate the operability of the selected equipment, the inspectors reviewed the system lineup checklists, normal operating procedures, abnormal and emergency operating procedures (EOPs), and current system drawings to verify the correct system lineup. During the walkdowns, the inspectors also examined valve positions and electrical power availability to verify that valve and electrical breaker positions were consistent with, and in accordance with, the licensees procedures and design documentation. The material condition of the equipment was also inspected.

b. Findings

No findings of significance were identified.

1R05 Fire Protection

.1 Fire Zone Inspections

a. Inspection Scope

During the inspection period, the inspectors walked down portions of the nine areas listed below to assess the overall readiness of fire protection equipment and barriers:

  • Accessible levels and areas of containment (Fire Zone RC-60) - April 9, 2003;
  • Accessible areas of steam generator and pressurizer vaults (Fire Zone RC-60) -

April 9, 2003;

  • Turbine building basement and mezzanine (Fire Zone TU-22) - April 17, 2003;
  • Accessible levels and areas of containment (Fire Zone RC-60) - April 30, 2003;
  • Safeguards battery rooms A and B - (Fire Zones TU-97 and TU-98) May 21, 2003;
  • Turbine building screenhouse (Fire Zone SC-70A) - May 21, 2003;
  • Relay room (Fire Zone AX-30) - June 24, 2003;
  • Control room and ventilation room (Fire Zone AX-35) - June 24, 2003; and
  • Control rod drive equipment room (Fire Zone AX-77) - June 27, 2003.

The inspectors focused on the licensees control of transient combustibles and ignition sources, the material condition of fire protection equipment, and the material condition and operational status of fire barriers used to mitigate fire damage or propagation.

Additionally, fire hoses, sprinklers, and portable fire extinguishers were inspected to verify that they were in satisfactory physical condition and were unobstructed. Passive features such as fire doors, fire dampers, and fire zone penetration seals were also inspected to verify that they were in satisfactory condition and capable of providing an adequate fire barrier.

b. Findings

No findings of significance were identified.

1R06 Flood Protection Measures

.1 Review of Internal Flood Protection Measures

a. Inspection Scope

The inspectors reviewed the internal flooding analysis for two areas during this inspection period. During the week of April 14, 2003, the inspectors performed a walkdown of flood zone 156-6, B component cooling water pump room. On May 14, 2003, the inspectors performed a walkdown of flood zone 3B, B DG room. These areas were walked down to determine whether existing configurations and mitigation plans were consistent with design requirements and risk analysis assumptions. The inspectors focused on the material condition and operational status of flood barriers used to mitigate flood damage and propagation.

Flood protection features such as flood doors and door gaps, drains, and flood zone penetration seals were also inspected to verify that they were in satisfactory physical condition, unobstructed, and capable of providing an adequate flood barrier. For those cases in which floor penetrations were not sealed, the inspectors verified that flooding leakage would not prevent the fulfillment of any safety function or adversely impact the operation of mitigating equipment. The inspectors also reviewed the maximum expected water levels in the pump room; calculated the resultant forces on the flood zone door; and estimated the shear strength of the door latches to ensure the door would remain intact during the postulated flooding scenario.

b. Findings

No findings of significance were identified.

.2 Review of External Flood Protection Measures

On May 14, 2003, the inspectors reviewed the design drawings for the facility trenwa to determine the susceptibility of the trenwa to flooding and the acceptability of its drainage capability. The trenwa was a covered concrete lined trench, which ran from the substation to the protected area, which contained control cables for various components located outside the protected area and in the substation. On May 30, the inspectors selected two locations in the trenwa for inspection and conducted a visual examination of the overall material condition of the trenwa and the cabling located inside. Additionally, the inspectors reviewed Procedure E-0-05, Natural Disaster, Revision J, which prescribed licensee actions in the event of flood warnings at the site.

The inspectors walked down the prescribed actions to verify that the actions could be performed.

b. Findings

No findings of significance were identified.

1R07 Heat Sink Performance

a. Inspection Scope

On May 12, 2003, the licensee conducted heat exchanger performance monitoring on the Containment Fan Cooling Units. The inspectors reviewed the test procedure, and reviewed the test data to verify that the test was performed as written, that the acceptance criteria were adequate to demonstrate acceptable heat transfer capability of the heat exchanger, and that the test data met the acceptance criteria. The inspectors also verified that the test accounted for instrument inaccuracies and that the test frequency was sufficient to provide early detection of heat exchanger degradation prior to any loss of heat removal capabilities below design values. Finally, the inspectors compared the current test results with previous test data to verify the performance of the heat exchangers.

b. Findings

No findings of significance were identified.

1R08 Inservice Inspection Activities

a. Inspection Scope

The inspectors reviewed the licensees inservice inspection (ISI) program for monitoring degradation of the reactor coolant system boundary and the risk significant piping system boundaries. Specifically, the inspectors observed activities in-process and reviewed records of nondestructive examinations.

The inspectors observed:

C Mechanized ultrasonic testing (UT) examination of steam generator 1B, feedwater pipe to nozzle weld FW-59; and C Liquid penetrant (PT) examination of safety injection socket weld SI-W29S.

The inspectors also reviewed the following reports:

C liquid penetrant examination of weld CVC-W90S; C liquid penetrant examination of weld RTD-W61B; and C Kewaunee R26 Eddy Current Summary Report.

These examinations were evaluated for compliance with the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code requirements. The inspectors also reviewed ISI procedures, personnel certifications, and NIS-2 forms for Code repairs performed during the last outage to confirm that ASME Code requirements were met.

The inspectors reviewed a sample of ISI related problems documented in the licensees corrective action program (CAP), to assess conformance with 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, requirements. In addition, the inspectors reviewed the licensees evaluation of operating experience for its applicability to the ISI program.

b. Findings

No findings of significance were identified.

1R11 Licensed Operator Requalification Program

a. Inspection Scope

On May 20, 2003, the inspectors observed a simulator dynamic requalification exam to evaluate crew performance, formality of communications, and annunciator response.

Additionally, the inspectors evaluated the operation crews implementation of the facilitys abnormal and emergency operating procedures, oversight and direction provided by the shift manager and control room supervisor, and the adequacy of identification and reporting of the event classification in accordance with the facilitys emergency plan. The inspectors also compared the simulator board configuration with the actual control room board configuration for consistency between the two to ensure that the simulator environment matched the actual control room environment as closely as possible. The inspectors observed the post-scenario critique to determine whether performance issues were accurately identified and addressed.

b. Findings

No findings of significance were identified.

1R12 Maintenance Effectiveness

a. Inspection Scope

During the week of May 5, 2003, the inspectors reviewed the implementation of the maintenance rule for the residual heat removal (RHR) system to verify that component and equipment failures were identified, entered, and scoped within the maintenance rule and that the system was properly categorized and classified as (a)(1) or (a)(2) in accordance with 10 CFR 50.65. The inspectors reviewed station logs, maintenance work orders, action requests, functional failure evaluations, unavailability records, and a sample of corrective action reports to verify that the licensee was identifying issues related to the maintenance rule at an appropriate threshold and that corrective actions were appropriate. Additionally, the inspectors reviewed the licensees performance criteria to verify that the criteria adequately monitored equipment performance.

b. Findings

No findings of significance were identified.

1R13 Maintenance Risk Assessment and Emergent Work Evaluation

a. Inspection Scope

During the inspection period, the inspectors reviewed the licensees evaluation and assessment of plant risk, scheduling, and configuration control for the five work-week schedules listed below. In particular, the licensees planning and management of maintenance was evaluated to verify that on-line risk was acceptable and in accordance with the requirements of 10 CFR 50.65(a)(4). Additionally, the inspectors compared the assessed risk configuration against the actual plant conditions and any in-progress evolutions or external events to verify that the assessment was accurate, complete, and appropriate. Licensee actions to address increased on-line risk during these periods were also inspected to verify that actions were in accordance with approved administrative procedures.

  • Shutdown safety assessment for April 7 through 11, 2003;
  • Shutdown safety assessment for April 21 through 25, 2003;
  • Safety Monitor risk assessment for May 19 through 23, 2003;
  • Safety Monitor risk assessment for June 9 through 13, 2003; and
  • Safety Monitor risk assessment for May 16 through 20, 2003.

b. Findings

No findings of significance were identified.

1R14 Personnel Performance During Non-Routine Plant Evolutions and Events

.1 Personnel and Equipment Response to Loss of Reactor Coolant System (RCS)

Inventory

a. Inspection Scope

On April 9, 2003, the inspectors reviewed the control room operators response to an inadvertent loss of RCS inventory which occurred when a tagout associated with the A Reactor Coolant Pump (RCP) was sequenced improperly resulting in a loss of approximately 100 gallons from the RCS. The plant was in refueling shutdown mode at the time of the event. The inspectors interviewed operators, reviewed plant computer data and trend recorders, reviewed operator logs, and evaluated equipment response to determine whether the operators response was in accordance with plant procedures.

Section 1R20.3 of this report documents additional issues associated with this event.

b. Findings

No findings of significance were identified.

.2 Refueling Outage Startup Observations

a. Inspection Scope

The inspectors observed the operators fill and vent the RCS following refueling of the reactor on May 3, 2003, and observed operators start the main turbine on May 10, 2003, to verify that plant procedures were followed and that control room activities were conducted in accordance with plant procedures.

b. Findings

No findings of significance were identified.

.3 Personnel and Equipment Response to a Rod Stop-Turbine Runback Signal

a. Inspection Scope

On June 10, 2003, the inspectors observed and reviewed the control room operators response to a rod stop-turbine runback signal which occurred during testing of Channel 1 (Red) of the Reactor Protection System. The inspectors interviewed operators and instrumentation and control technicians, reviewed plant computer data and trend recorders, reviewed operator logs, and evaluated the equipment response to determine whether the operators response was in accordance with plant procedures.

b. Findings

No findings of significance were identified.

1R15 Operability Evaluations

a. Inspection Scope

The inspectors reviewed the four licensee corrective action documents listed below describing equipment questions and issues for risk significant systems to determine the acceptability of the associated operability evaluations. The inspectors reviewed applicable design information and Technical Specifications to assess the adequacy of the evaluations and implementation of applicable compensatory measures. The inspectors review included verification that the operability determinations were made in accordance with Procedure GNP 11.08.03, Operability Determination, Revision B.

  • CAP 16003; B DG heat exchanger tube bundle nuts not staked;
  • CAP 15980; SI-5B-1 relief valve operability; and

b. Findings

No findings of significance were identified.

1R16 Operator Workarounds (OWAs)

.1 Control Room Deficiency Tags

a. Inspection Scope

On June 27, 2003, the inspectors reviewed the licensees control room deficiency log, out-of-service control room indicators and equipment logs to verify the licensees identified operator workarounds. The inspectors also reviewed posted danger cards located in the control room to assess whether known degraded or out-of-service equipment in the control room would impact operator response to plant transients or emergencies and therefore be considered potential operator workarounds.

b. Findings

No findings of significance were identified.

1R17 Permanent Plant Modifications

a. Inspection Scope

The inspectors reviewed the engineering analyses, design information and modification documentation for the replacement of the component cooling water heat exchangers during the facilitys refueling outage.

  • Containment penetration controls, to verify that they were in accordance with technical specifications;
  • Refueling activities and fuel movement, to ensure that technical specifications were met and that site refueling procedures were followed;
  • Plant startup and heatup, including walkdowns of containment to ensure that debris had not been left which could affect performance of containment sumps; and
  • Licensee identification and resolution of outage related problems.

b. Findings

No findings of significance identified.

.2 Failure to Maintain Design Requirements of RHR System

a. Inspection Scope

The inspectors reviewed the licensees response and followup investigation following the discovery that piping components installed in the RHR system were made of carbon steel and not stainless steel as required by facility engineering specifications.

b. Findings

Introduction A Green self-revealed finding associated with a NCV was identified for the licensees failure to ensure that the residual heat removal system piping materials were in accordance with plant design specifications as required by 10 CFR 50, Appendix B, Criterion V.

Description On April 5, 2003, in preparation for cooling the reactor coolant system below 350 degrees Fahrenheit during the refueling outage, control room operators placed the residual heat removal system in service. Shortly afterwards, the operators were notified that a leak had developed on a plug located in a pressure tap connection associated with the B train RHR pump recirculation line pressure breakdown orifice. Upon receipt of this information, the operators secured both trains of RHR. The licensee determined that the plug material was of carbon steel and that it had corroded due to the presence of boric acid in the RHR system fluid. The RHR system normally contains borated water to ensure that the reactor is subcritical during accident conditions.

The licensee documented the issue in CAP 15530. The licensee determined, as documented in Apparent Cause Evaluation 2221, that two other carbon steel plugs were installed in the A RHR pump recirculation piping. The licensee concluded that the additional carbon steel plugs were also corroded, but not to the extent such that near term leakage was likely. The licensee reviewed the maintenance history for the RHR pump recirculation piping. The licensee did not determine when the carbon steel plugs had been installed nor identify any maintenance work packages which affected the pipe plugs.

Additionally, the licensee conducted an extent of condition review of other systems which contain borated water. The review consisted of examining readily accessible piping located in the penetration rooms, chemical and volume control system piping, safety injection system piping, containment spray system piping, and uninsulated portions of the boric acid pumps. No additional carbon steel plugs were identified. Drawing XK-100-18, Flow Diagram Auxiliary Coolant System, Revision AK, required that RHR system recirculation piping be made of stainless steel. The licensee subsequently replaced all three carbon steel plugs with stainless steel plugs and returned the RHR system to service.

Analysis The inspectors determined that the licensees failure to maintain configuration control by ensuring that the pipe plugs installed in the RHR pump recirculation piping were stainless steel in accordance with Drawing XK-100-18 was a performance deficiency warranting a significance evaluation. This self-revealed finding was greater than minor because the failure to maintain the design of the RHR system affected the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of a system designed to respond to an initiating event.

Although the reactor was shutdown at the time of this event, the finding was evaluated using Appendix A of Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP) of Reactor Inspection Findings for At-Power Situations. The inspectors considered this to be acceptable since Appendix G of IMC 0609, Shutdown Operations Significance Determination Process, was applicable only once RHR cooling had been initiated and the RHR system had remained in this configuration during power operation over the previous at-power cycle.

The inspectors determined that the finding was of very low safety significance (Green)because the finding represented a design or qualification deficiency which did not result in a loss of function per Generic Letter 91-18, Information to Licensees Regarding NRC Inspection Manual Section on Resolution of Degraded and Nonconforming Conditions, Revision 1.

Enforcement 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedure, or drawings, and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to this, as of April 5, 2003, the licensee failed to ensure that pipe plugs installed in both trains RHR pump recirculation piping pressure breakdown orifices were stainless steel in accordance with Drawing XK-100-18. Therefore, the inspectors determined this finding was a violation of 10 CFR 50, Appendix B, Criterion V. Because this violation was of very low safety significance and was documented in the licensees corrective action program as CAP 15530, it is being treated as a NCV, consistent with Section VI.A of the NRC Enforcement Policy. (NCV 50-305/03-04-01)

.3 Improper Tagout Sequence Results in Loss of RCS Inventory

a. Inspection Scope

The inspectors reviewed the licensees response and investigation into an inadvertent loss of RCS inventory which occurred when a tagout for the A Reactor Coolant Pump (RCP) was not processed in accordance with plant procedures. The inspectors interviewed licensee personnel on actions taken and reviewed plant parameters following the event to ensure that core cooling was not challenged. (See also Section 1R14.1 of this report.)

b. Findings

Introduction A Green self-revealed finding associated with a NCV was identified for the licensees failure to properly sequence a tagout associated with isolation of the A RCP in accordance with the licensees tagout procedure. The improper tagout sequence resulted in a loss of inventory from the RCS.

Description On April 9, 2003, with the plant in refueling shutdown mode and reactor vessel level at 20.6 percent, the licensee was in the process of hanging Tagout 03-266 when control room operators noted that reactor vessel level was decreasing. The operators took immediate action to stabilize and maintain reactor vessel level. The minimum reactor vessel level noted during the transient was 20.4 percent. Tagout 03-266 was hung to isolate the A RCP in preparation for replacement later in the outage. A licensee investigation revealed that the loss of RCS inventory was due to the opening of the A RCP vent and drain valves per Tagout 03-266 without the RCP shaft lowered and backseated to provide an RCS leakage boundary. This configuration resulted in a loss of approximately 100 gallons from the RCS to the A containment sump.

The licensees outage schedule had sequenced the tagout to be placed after the A RCP was backseated. However, this information was not communicated to the work control center supervisor who authorized Tagout 03-266 to be performed. Additionally, the licensees review of the event revealed that the work control supervisor who authorized Tagout 03-266 was uncertain if the plant conditions were acceptable for venting and draining the RCP. The inspectors also noted that Procedure GNP 03.03.01, Tagout Processing, Revision N, provided conditions to be considered in preparing equipment for isolation including draining and venting. The licensee documented the issues in their corrective action program as CAP 15628. Additionally, the licensee conducted Root Cause Evaluation 611 to determine the underlying causes and issues associated with this event and a similar loss of inventory event which occurred later during the refueling outage (see Section 1R20.4 of this report, Inadvertent Installation of Blank Flange as a Foreign Material Exclusion Cover Results in Conflicting Reactor Vessel Level Indications, for more details concerning this second issue).

Analysis The inspectors determined that the licensees failure to sequence Tagout 03-266 without appropriate consideration to plant conditions and the impact of opening the A RCP vent and drain valves which resulted in the reactor vessel level transient was a performance deficiency warranting a significance evaluation. This self-revealed finding was greater than minor because the failure to properly hang Tagout 03-266 affected the Initiating Events Cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors determined that a contributing cause of this event was related to the cross-cutting area of human performance.

Using the PWR Cold Shutdown and Refueling Operation RCS Open and Refueling Cavity Level < 23' OR RCS Closed and No Inventory in Pressurizer Time to Boiling Less Than 2 Hours, checklist in Appendix G of IMC 0609, Shutdown Operations Significance Determination Process, the inspectors determined that the finding was of very low safety significance (Green) because the finding did not affect the checklist attributes and therefore did not warrant a Phase 2 SDP evaluation.

Enforcement Title 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, required, in part, that activities affecting quality shall be prescribed by documented instructions, procedure, or drawings, and shall be accomplished in accordance with these instructions, procedures, or drawings. Licensee procedure GNP 03.03.01, Tagout Processing, Revision N, Step 6.1.6.d, required, in part, that the Work Control Supervisor shall evaluate the conditions to be considered in preparing equipment for isolation including, as a minimum, draining and venting. Contrary to this requirement, on April 9, 2003, the Work Control Supervisor failed to evaluate the conditions to be considered in preparing the RCP for isolation, including draining and venting.

Subsequently, licensee personnel hung Tagout 03-266 to isolate, vent and drain the A RCP prior to the RCP being backseated, which resulted in a loss of RCS inventory. The inspectors determined this finding was a violation of 10 CFR 50, Appendix B, Criterion V.

Because this violation was of very low safety significance (Green) and was documented in the licensees corrective action program as CAP 15628, it is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy. (NCV 50-305/03-04-02)

.4 Inadvertent Installation of Blank Flange as a Foreign Material Exclusion Cover Results in

Conflicting Reactor Vessel Level Indications

a. Inspection Scope

The inspectors reviewed the licensees response and investigation into conflicting reactor vessel level indications which occurred when a blank flange was inadvertently installed on the reactor vessel head vent. The inspectors interviewed plant personnel and reviewed plant parameters following the event to verify that core cooling was not challenged.

b. Findings

Introduction A Green self-revealed finding associated with a NCV was identified for the licensees failure to ensure that the procedure governing refueling operations and reactor head disassembly had appropriate instructions or cautions to ensure that the reactor head vent remained vented to containment atmosphere thereby ensuring proper operation of the refueling cavity water level instrument.

Description On April 10, 2003, control room operators noted a decreasing trend on Reactor Vessel Level Indication System (RVLIS) and an increasing trend of refueling cavity water level indication. Both indications were used by the operators to monitor current reactor vessel level indication which was initially at 20.6 percent; however, the inspectors noted that operators typically utilized refueling cavity water level indication to control reactor vessel level. The inspectors noted that there were two trains of RVLIS indication available to the operators, while there was only a single train of refueling cavity water level indication.

During subsequent troubleshooting efforts of the differing level indications, the licensee determined that following the removal of the reactor vessel head vent spoolpiece, which had been removed in support of refueling activities per Procedure RF-01.00, KNPP Refueling Procedure, that a metal blank flange was installed on the vessel head vent as a foreign material exclusion cover consistent with the licensee procedure on general foreign material exclusion practices.

The blank flange prevented the venting of non-condensible gases which had come out of solution from the RCS, and caused a gas pocket to form under the reactor vessel head.

With a gas pocket forming, refueling cavity water level indicated an increasing trend since water displaced from the gas pocket caused an increased differential pressure on the instrument which resulted in a higher indicated level than actual reactor vessel level.

Concurrently, RVLIS was not affected by the increased differential pressure and accurately indicated a decreasing vessel level due to the gas pocket which was forming.

While the vessel level indications were in question, the operators controlled vessel level based on RVLIS which indicated the lower vessel level. At no time did the gas pocket interfere with the capabilities of plant systems to remove decay heat from the reactor.

After the licensee discovered that the blank flange had been installed, the blank flange was removed and the vessel head was vented returning the refueling cavity water level indicator to a normal configuration. During the evolution, reactor vessel level was noted to have lowered to approximately 20.5 percent. The licensee documented the transient in their corrective action program as CAP 15673. Additionally, the licensee conducted Root Cause Evaluation 611 to determine the factors and causes which led to the configuration control problem of the vessel head vent path.

Analysis The inspectors determined that the licensees failure to have appropriate instructions or cautions in Procedure RF-01.00 to ensure that the reactor vessel head vent remained vented to atmosphere was considered a licensee performance deficiency warranting a significance evaluation. This self-revealed finding was greater than minor because the failure to ensure that the vessel head remained vented to atmosphere was considered a configuration control issue of an instrument the licensee relied upon for maintaining proper reactor vessel level. It also affected the Initiating Events Cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations.

Using the PWR Cold Shutdown and Refueling Operation RCS Open and Refueling Cavity Level < 23' OR RCS Closed and No Inventory in Pressurizer Time to Boiling Less Than 2 Hours, checklist in Appendix G of IMC 0609, Shutdown Operations Significance Determination Process, the inspectors determined that the finding was of very low safety significance (Green) because the finding did not affect the checklist attributes and therefore did not warrant a Phase 2 SDP evaluation.

Enforcement Title 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, required, in part, that activities affecting quality shall be prescribed by documented instructions, procedure, or drawings of a type appropriate to the circumstances.

Contrary to this requirement, Procedure RF-01.00, KNPP Refueling Procedure, Step 5.2.8, Revision J, directed removal of the reactor vessel head vent spool piece, but did not provide additional instructions or cautions to ensure that the reactor vessel head vent would remain unblocked and vented to containment atmosphere; therefore, the procedure was not appropriate to the circumstances. The inspectors determined this finding was a violation of 10 CFR 50, Appendix B, Criterion V. Because this violation was of very low safety significance (Green) and was documented in the licensees corrective action program as CAP 15673, it is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy. (NCV 50-305/03-04-03)

The inspectors also reviewed the stations overall source term reduction plan, which included improved tracking/mitigation of hot spots and tracking/trending of online/shutdown chemistry initiatives. The inspectors reviewed the licensee's continuing source term reduction techniques to verify that source term control strategies were ongoing and future initiatives were being explored.

b. Findings

No findings of significance were identified.

.2 Job Site Inspections and ALARA Controls

a. Inspection Scope

The inspectors reviewed the licensees use of ALARA controls for selected 2003 refueling outage work activities performed in radiation areas, HRAs, and LHRA.

Specifically, the inspectors reviewed the adequacy of RWPs, radiological surveys, attended pre-job radiological briefings, and assessed job site ALARA controls for the following work activities:

  • Assembling and Building Scaffolding Within Containment;
  • Work Activities in Support of In Service Inspections; and
  • Disassemble and Removal of the Reactor Head.

For each activity the inspectors examined worker instruction requirements which included protective clothing, engineering controls to minimize dose exposures, the use of predetermined low dose waiting areas, as well as the on-the-job supervision by the work crew leaders to verify that the licensee had maintained the radiological exposure for these work activities ALARA. The inspectors evaluated radiation protection technician (RPT) performance for each of the aforementioned work evolutions, as well as observing and questioning workers at each job location to verify that they had adequate knowledge of radiological work conditions and exposure controls.

b. Findings

No findings of significance were identified.

.3 Radiological Work/ALARA Planning

a. Inspection Scope

The inspectors observed radiation workers and RPTs during high dose rate or high exposure jobs to determine whether workers demonstrated the ALARA philosophy in practice. Specifically, the inspectors observed the work activities to determine whether workers were familiar with the job scope and tools to be used, whether workers were using low dose waiting areas, and whether the workers demonstrated that their training/skill levels was sufficient with respect to the radiological hazards and the work involved.

b. Findings

No findings of significance were identified.

.4 Radiological Work/ALARA Planning

a. Inspection Scope

The inspectors examined the stations procedures for radiological work/ALARA planning and scheduling, and evaluated the dose projection methodologies and practices implemented for the 2003 refueling outage to verify that sound technical bases for outage dose estimates existed. The inspectors reviewed selected radiologically significant ALARA planning packages for work activities during the 2003 refueling outage work activities. Those ALARA plans addressed refueling activities, steam generator inspection activities, in-service inspections, reactor coolant pump work activities, as well as the installation and removal of shielding and insulation. The inspectors conducted the reviews to verify that adequate person-hour estimates, job history files, lessons learned, and industry experiences were utilized in the ALARA planning process. In addition, the reviews were conducted to verify that ALARA requirements were integrated into work procedure and RWPs, and work activities were scheduled to consider the benefits of dose reduction activities.

b. Findings

No findings of significance were identified.

.5 Verification of Exposure Estimate Goals and Exposure Tracking System

a. Inspection Scope

The inspectors reviewed the methodology and assumptions used by the licensee for its 2003 refueling outage exposure estimates and exposure goals. Actual job exposure data was compared with estimates to verify that the licensee could project and, thus, control radiological exposure. The inspectors also reviewed the licensees exposure tracking system to verify that the level of exposure tracking detail, exposure report timeliness, and exposure report distribution were sufficient to support control of collective exposures. The inspectors evaluated how the licensee had identified problems with its exposure estimates for some jobs, the processes being utilized to revise dose estimates, and methods to improve its dose forecasting procedures to verify that the licensee could adequately track dose.

b. Findings

No findings of significance were identified.

.6 Declared Pregnant Workers

a. Inspection Scope

The inspectors reviewed the stations dose minimization controls used for declared pregnant workers. Specifically, the inspectors reviewed the licensees adherence to the requirements contained in 10 CFR 20.1208 by examining the licensees fetal protection program procedure for tracking radiological exposure to the embryo/fetus, and the administrative and ALARA controls that could be used by the licensee to minimize the dose to the embryo/fetus of a declared pregnant worker.

b. Findings

No findings of significance were identified.

.7 Identification and Resolution of Problems

a. Inspection Scope

The inspectors reviewed selected corrective action documents, (i.e., Kewaunee Assessment Program (KAP) documents), and discussed the documents with Radiation Protection Program staff and management to determine if problem characterization was accurate, and to verify that extent of condition reviews were adequately completed or were in the process of being performed.

b. Findings

4OA3 Event Follow-up

.1 (Closed) Licensee Event Report (LER) 50-305/2003-001-00 Technical Specifications

Action Requirements Not Followed - Personnel Failed to Follow Procedure This LER documented the licensees failure to meet technical specifications when an axial flux differential monitor alarm was inadvertently disabled when operators responded to an associated nuisance alarm. This finding, associated enforcement, and human performance aspect was documented and dispositioned in NRC Inspection Report 50-305/03-02, Sections 1R15 and 4OA4. The inspectors reviewed the LER and no additional findings of significance were identified. The licensee documented the corrective actions in CAP 14321 and 14328. This LER is closed.

.2 (Open/Closed) Failure to Report A Fitness-for-Duty Event

a. Inspection Scope

The inspectors reviewed licensee action regarding the identification of illegal drugs within the licensees protected area.

b. Findings

Introduction:

The inspectors identified that the licensee failed to report a Fitness-for-Duty (FFD) event as required by NRC 10 CFR 26.73

(a) requirements. The issue when evaluated by the NRC was considered to be of very low safety significance and was dispositioned as a Severity Level IV Non-Cited Violation (NCV).
Description:

On May 28, 2003, a plant employee, while walking in the facilitys protected area found, a small plastic bag on the ground which contained a leafy material.

There were no personnel observed in the area were the bag was found. The plant staff member took possession of the plastic bag and immediately contacted security. At approximately 7:30 a.m. onsite field testing of the leafy material proved positive for a controlled substance. The plastic bag and substance was turned over to the local police department for investigation and disposal.

After finding the item and confirming its contents, the need to report the issue to NRC was reviewed. Personnel involved in the process included representatives from the licensees plant security and the site licensing staff, along with a senior corporate management FFD representative. The licensee concluded that the FFD event did not represent a significant issue/event and that logging the event was the appropriate decision. The decision was based on licensee analysis that the discovery of the substance (contraband) in and of itself was not a significant threat to the site, and that NRC FFD reporting criteria required actual possession by a person to represent a significant FFD event.

Later that same day, as a courtesy, the licensees security manager contacted a Region III physical security inspector to advise the Region of the event, and the licensees decision to log the event. The inspector questioned the licensees conclusion based on information contained in Section 10.7 of NRC NUREG-1385, Fitness-for-Duty in the Nuclear Power Industry: Responses to Implementation Questions," which identified and documented a question and answer that supported the reporting of such an event to the NRC. The question and answer as stated in NUREG-1385:

Question:

Should finding alcohol or drugs within the protected area (no person in possession) be reported?

NRCs response:

Yes. Possession would be inferred and would be required to be reported as a significant FFD event under the meaning of 10 CR26.73(a).

After further evaluating their discussion with the inspector and identifying that they were not familiar with NUREG-1385, the licensee reported the event to the NRC Operation Center at approximately 11:40 a.m. on May 29, 2003.

Analysis:

This issue was evaluated and dispositioned using the NRC Significant Determination Process (SDP), for the Physical Protection cornerstone. The issue was screened through the Physical Protection SDP. The inspectors determined that the finding was more than minor issue because it involved a failure to meet NRC regulatory requirements noted in 10 CFR 26.73(a) that involved the reporting of significant FFD events to the NRC. The finding further represented a vulnerability in a licensees plan, was not a malevolent act, and greater than two similar findings had not occurred in four calendar quarters. Therefore, the inspectors concluded the issue was of very low safety significance. In this case the licensee demonstrated less than prudent judgement by not recognizing that this event should have been reported as a significant FFD.

Enforcement:

Title 10 CFR 26.73(a) requires, in part, that the licensee inform the Commission of significant Fitness-for-Duty events including possession of illegal drugs within the protected area by notification to the NRC Operations Center by telephone within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the discovery of the event by the licensee. Contrary to this, on May 28, 2003, the licensee failed to report a significant Fitness-for-Duty event that involved possession of illegal drugs within the licensees protected area to the NRC Operations Center within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of discovery. The results of the violation were determined to be of very low safety significance; therefore, this violation of 10 CFR 26.73 was classified as a Severity Level IV violation. This Severity Level IV violation is being treated as a Non-Cited Violation (NCV), consistent with Section VI.A.1 of the NRC Enforcement Policy (NCV 50-305-03-04-04). This violation is documented in the licensees corrective action program as CAP 033527.

4OA4 Cross-Cutting Findings

The finding described in Section 1R20.3 of this report, Improper Tagout Sequence Results in Loss of RCS Inventory, had as a contributing cause, a human performance deficiency, in that, a work control supervisor authorized the processing of a tagout when the supervisor was uncertain that the plant conditions were appropriate. The processing of the tagout resulted in an inadvertent loss of RCS inventory while the unit was in refueling shutdown mode.

4OA5 Other Activities

.1 Reactor Pressure Vessel Head and Vessel Head Penetration Nozzles (TI 2515/150)

a. Inspection Scope

The objective of TI 2515/150, Revision 1, Reactor Pressure Vessel Head and Vessel Head Penetration Nozzles, was to implement an on-site NRC review of the licensees activities in response to NRC Bulletin 2002-02, Reactor Pressure Vessel Head and Vessel Head Penetration Nozzle Inspection Programs, to verify compliance with applicable regulatory requirements. In response to NRC Bulletin 2002-02, Kewaunee Nuclear Plant calculated the effective degradation years based on time and head temperature which placed the plant in the Moderate Susceptibility ranking for leakage of the penetration nozzles. As a result, the licensee performed a 100 percent bare metal visual inspection of the reactor pressure vessel (RPV) head and penetration nozzles.

The inspectors interviewed inspection personnel, reviewed procedures and inspection reports, including photographic documentation, to assess the licensees efforts in conducting the visual examination of the RPV head.

Summary The licensee did not identify any leaking vessel head penetration nozzles (VHP).

b. Evaluation of Inspection Requirements In accordance with requirements of TI 2515/150, the inspectors evaluated and answered the following questions:

a. Was the examination:

1. Performed by qualified and knowledgeable personnel?

Yes. The inspectors verified that the examination was performed by five examiners certified in both VT-1 and VT-3 Methods to at least Level II (one examiner was a Level III), with additional training specific to Electric Power Research Institute (EPRI) Procedure 1006296 Revision 1, Visual Examination for Leakage of PWR Reactor Head Penetrations on Top of RPV Head.

2. Performed in accordance with demonstrated procedures?

No volumetric examinations were conducted during this outage. The inspectors verified that the bare metal visual examinations were conducted in accordance with NEP No. 15.5, Revision 0, Visual Examination for Inservice Inspection, and that EPRI Procedure 1006296 Revision 1, Visual Examination for Leakage of PWR Reactor Head Penetrations on Top of RPV Head was used in the pre-job briefing notes and documented as being used as guidance for the examination.

Kewaunee has block contoured vessel head insulation, consisting of mirror panels fabricated of 4 inch thick perforated metal block insulation. The inspectors verified that the insulation and shroud were completely removed and the as-found head was clean, with no viewing obstructions to the exam. There were 41 penetrations, including the 3/4" head vent, which were fully examined.

Loose surface debris on the uphill side of penetrations and staining of control rod drive mechanism lengths were observed.

3. Able to identify, disposition, and resolve deficiencies?

Yes. The inspectors concluded from the review of the photographic documentation that the licensee had sufficient access to perform a direct visual examination with 360 degree coverage of each penetration. The procedural resolution requirements (able to discern a 1/32 inch black line on an 18 percent neutral gray card) for the direct visual examination of the vessel head was adequate to detect boric acid deposits.

4. Capable of identifying the primary water stress corrosion cracking phenomenon described in the bulletin?

Yes. The inspectors determined through interviews with inspection personnel, reviews of the Visual Examination Record, and photographic documentation that the licensees efforts were capable of detecting and characterizing VHP nozzle leakage.

b. What was the condition of the reactor head (debris, insulation, dirt, boron from other sources, physical layout, viewing obstructions)?

Kewaunee has block contoured vessel head insulation, consisting of mirror panels fabricated of 4 inch thick perforated metal block insulation. The inspectors verified that the insulation and shroud were completely removed and the as-found head was clean, with no viewing obstructions to the exam. There were 41 penetrations, including the 3/4 inch head vent, which were fully examined. Loose surface debris on the uphill side of penetrations and staining of control rod drive mechanism lengths were observed.

c. Could small boron deposits, as described in Bulletin 2001-01, be identified and characterized?

Yes. The inspectors determined through interviews with inspection personnel, reviews of the inspection procedure and examination reports, that small boron deposits, as described in the Bulletin 2001-01, could be identified and characterized.

d. What material deficiencies (associated with the concerns identified in the bulletin)were identified that required repair?

There were no material deficiencies associated with the 41 VHP nozzles that were considered indicative of leakage.

e. What, if any, significant items that could impede effective examinations?

None. The licensee had sufficient access to perform a direct visual examination with 360 degree coverage of each penetration f. What was the basis for the temperatures used in the susceptibility ranking calculation?

In Bulletin 2002-02, the Effective Degradation Years (EDY) is used as a basis to establish appropriate inspection programs for VHP nozzles based on increasing susceptibility to nozzle cracking with increasing EDY. Calculation No. C11470, Reactor Vessel Head Effective Degradation Year (EDY), uses a reactor pressure vessel head temperature of 583 degrees F., which is the published value in MRP-48, PWR Materials Reliability Program Response to NRC Bulletin 2001-01, dated August 2001.

c. Findings

No findings of significance were identified.
