SUBJECT: KEWAUNEE POWER STATION - NRC INTEGRATED INSPECTION REPORT 05000305/2006005; 05000305/2006014
Dear Mr. Christian:
On December 31, 2006, the U.S. Nuclear Regulatory Commission (NRC) completed aninspection at your Kewaunee Power Station. The enclosed integrated inspection report documents the inspection findings, which were discussed on January 3, 2007, with Ms. L. Hartz and other members of your staff.The inspection examined activities conducted under your license as they relate to safety andcompliance 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, there were one self-revealed and two NRC-identified findings of very low safety significance, all of which involved a violation of NRC requirements.
However, because these violations were of very low safety significance and because the issues were entered into your corrective action program, the NRC is treating these findings as Non-Cited Violations (NCVs), in accordance with Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator - Region III, 2443 Warrenville Road, Suit e 210, Lisle, IL 60532-4352;the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Kewaunee Power Station.

SUMMARY OF FINDINGS
IR 05000305/2006005 and IR 05000305/2006014; 10/01/2006 - 12/31/2006; Kewaunee PowerStation. Fire Protection, and Refueling and Other Outage Activities.This report covers a 3-month period of inspection by resident inspectors and announcedinspections by regional specialists. The emergency preparedness portion of this inspection is being tracked using Inspection Report (IR) 05000305/2006014. Three Green findings with associated Non-Cited Violations (NCVs) were identified. The significance of most findings isindicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC)0609, "Significance Determination Process" (SDP). Findings for which the SDP does not apply may be "Green" or be assigned a severity level after NRC management review. The 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.
NRC-Identified
and Self-Revealed Findings
Cornerstone: Initiating Events
- Green.
A finding of very low safety significance and an associated NCV of TechnicalSpecification 6.8, "Procedures," was identified by the inspectors for the failure to identify radiological and toxic hazards in the cable spreading area fire zone pre-fire strategy.
These hazards were from a radioactively contaminated lead pipe in the fire zone that could melt during certain fire scenarios. As part of corrective actions, the licensee appropriately revised the strategy. The issue was entered into the licensee's corrective action program.The finding is greater than minor because it was associated with the external factors -fire attribute of the Initiating Events cornerstone and affected the 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. Specifically, the failure to provide adequate warnings and guidance in the pre-fire plan related to these hazards could have adversely impacted the fire brigade's ability to properly respond to a fire.
This impact could increase the likelihood of damage to equipment, causing an upset pf plant stability. NRC management review determined the finding to be of very low safety significance (Green), due to the extensive training provided to fire brigade members to deal with unexpected contingencies. This finding has a cross-cutting aspect in the area of human performance because the licensee failed to provide complete, accurate, and up-to-date pre-fire strategies for the fire brigade to respond to a fire. (Section 1R05)
Cornerstone: Mitigating Systems
- Green.
A finding of very low safety significance and an associated non-cited violation of10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," was self-revealed during performance of a plant safety-related procedure to fill and vent the containment spray system, on October 11, 2006, when water was inappropriatelydiverted from the reactor coolant system to the residual heat removal system. As part ofcorrective actions, the licensee revised the procedure to ensure the systems were 2properly aligned during fill and vent activities. The issue was entered into the licensee'scorrective action program.This finding is greater than minor because if left uncorrected it would become a moresignificant safety concern in that the use of other inadequate procedures could have rendered inoperable important mitigating equipment, such as the containment spray and residual heat removal systems. Additionally, the finding was associated with the procedure quality and configuration control attributes of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The finding was determined to be of very low safety significance (Green) because it did not require a quantitative assessment. This finding has a cross-cutting aspect in the area of human performances because the licensee failed to provide complete, accurate, and up-to-date procedures to fill and vent the containment spray system. (Section 1R20.1)
- Green.
A finding of very low safety significance and an associated NCV of TechnicalSpecification 6.8, "Procedures," was identified by the inspectors on October 23, 2006, for the failure to install scaffolding in accordance with station procedures. Specifically, scaffolding was installed inside containment that was too close to, or was in contact with, safety injection system components and piping. As part of corrective actions, the licensee removed the scaffolding and enhance the station procedure for scaffolding.
The issue was entered into the licensee's corrective action program.This finding is greater than minor because it was associated with the equipmentperformance attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage).
Specifically, improperly positioned scaffolding could have impeded or prevented proper operation of the safety injection system during an accident. The finding was of very low safety significance (Green) because it did not require a quantitative assessment. This finding has a cross-cutting aspect in the area of human performances because personnel did not follow the procedure for scaffolding. (Section 1R20.2)
B.Licensee-Identified Violations
None.

1R05 Fire Protection (71111.05)
.1 Quarterly Fire Zone Walkdowns
a. Inspection Scope
The inspectors walked down risk significant fire areas to assess fire protectionrequirements. The inspectors reviewed areas to assess if the licensee had implemented a fire protection program that adequately controlled combustibles and ignition sources within the plant, effectively maintained fire detection and suppression capability, maintained passive fire protection features in good material condition, and had implemented adequate compensatory measures for out-of-service, degraded, or inoperable fire protection equipment, systems, or features. The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the plant's Individual Plant Examination of External Events, or the potential to impact equipment which could initiate or mitigate a plant transient. The inspection activities included, but were not limited to, the control of transient combustibles and ignition sources, fire detection equipment, manual suppression capabilities, passive suppression capabilities, automatic suppression capabilities, compensatory measures, and barriers to fire 6propagation. As part of this inspection, the documents listed in the Attachment werereviewed.The inspectors selected the following areas for review for a total of six samples:
- Fire Zone AX-32, Cable Spreading Area;*Fire Zone TU-94, CO2 Storage Tank Room;
- Fire Zone AX-30, Relay Room and Loft;
- Fire Zone TU-97,98, Battery Rooms 1A & 1B;
- Fire Zone AX-23A, Hot Chemistry Lab; and
- Fire Zone TU-92, 1B Diesel Generator.
b. Findings
Introduction:
A finding of very low safety significance (Green) and an associatedNon-Cited Violation (NCV) of Technical Specification (TS) 6.8, "Procedures," was identified by the inspectors for the failure to identify radiological and toxic hazards in the cable spreading area fire zone pre-fire strategy.
Description:
The inspectors identified lead piping in the overhead of the cable spreadingroom while performing a fire zone inspection during December 2006. The piping was identified as a potentially radiologically contaminated system. The inspectors were concerned that in the event of a fire the melting point for this piping could be reached creating molten lead, an airborne toxic lead atmosphere, and potentially a radiological hazard. The inspectors reviewed the pre-fire strategies used to prepare the fire brigade when responding to a fire in this area and noted that these hazards and the lead pipe were not identified in the strategies.Analysis: The inspectors determined that the failure to include the radiological hazardsand the presence of the lead, both molten and lead vapors, in the Fire Area Strategies book is a performance deficiency warranting a significance evaluation. Using Inspection Manual Chapter (IMC) 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Screening," dated November 2, 2006, the inspectors concluded that the finding is greater than minor because it was associated with the external factors - fire attribute of the Initiating Events cornerstone and affected the 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. Specifically, the failure to provide adequate warnings and guidance in the pre-fire plan related to these hazards could have adversely impacted the fire brigade's ability to properly respond to a fire.
Procedure E-FP-08, "Emergency Operating Procedure - Fire," Step 4.13, requires the fire brigade to "refer to the Fire Area Strategies book for planning Fire Brigade actions." In accordance with IMC 0609, "Significance Determination Process" (SDP), Appendix A,"Determining the Significance of Reactor Inspection Findings for At-Power Situations, dated November 22, 2005, the inspectors performed an SDP Phase 1 screening and determined that the finding affected fire protection defense-in-depth strategies.
However, as discussed in IMC 0609, Appendix A, Attachment 1, issues related to performance of the fire brigade are not included in IMC 0609, Appendix F, "Fire Protection Significance Determination Process," dated February 28, 2005, and require 7management review. Therefore, the finding was reviewed by NRC management, andwas determined to be a finding of very low safety significance (Green) due to the extensive training provided to fire brigade members to deal with unexpected contingencies. Additionally, the inspectors determined that this finding has a cross-cutting aspect in the area of human performance because the licensee failed to provide complete, accurate, and up-to-date pre-fire strategies for the fire brigade to respond to a fire.
Enforcement:
Licensee TS 6.8, "Procedures," Paragraph a., requires that writtenprocedures meet the requirements of Sections 5.2.2, 5.2.5, 5.2.15 and 5.3 of American National Standards Institute (ANSI) N18.7-1976. Section 5.3.2
- (5) of ANSI N18.7-1976 specifies that precautions should be established to alert individuals performing tasks to measures which should be used to protect equipment and personnel.Contrary to the above, the licensee's pre-fire plan for Fire Zone AX-32, Cable SpreadingArea, did not identify any potential radiological and toxic hazards. Specifically, the pre-fire plan did not identify the hazards associated with potentially contaminated lead piping in this area. After a discussion of this issue with the inspectors, the licensee entered the finding into its corrective action program as CAP039885, "NRC Questions on Cable Spreading Room Lead Pipe," and CAP040360, "PFP-24, Fire Strategy Lacks Hazard Identification for Lead and Radiation." The immediate action taken by the licensee was to revise the affected pre-fire strategy. Proposed actions included procedure revisions to better manage the pre-fire strategies and a review of all pre-fire strategies and drawings. Because this violation was of very low safety significance and was entered into the corrective action program, this violation is being treated as a NCV (NCV 05000305/2006005-01), consistent with Section VI.A.1 of the NRC Enforcement Policy.
1R11 Licensed Operator Requalification Program

b. Findings
.1Inadvertent Drain Down of the RCS During Fill and Vent of the Containment SpraySystemIntroduction: A finding of very low safety significance (Green) and an associated NCV of10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," was self-revealed during performance of a plant safety-related procedure to fill and vent the containment spray (ICS, internal containment spray) system when water was inappropriately diverted from the RCS to the RHR system.
12 Discussion: During September and October, 2006, the plant was in a refuelingshutdown outage. On October 11, 2006, during the performance of nuclear safety-related procedure N-ICS-23A, "Fill And Vent of ICS," the control room operators observed that reactor vessel level began to decrease from the initial level of 20.6 percent, which was approximately 6 inches below the reactor vessel flange. In response, operators increased charging flow to restore level and began an investigation to determine the cause of the problem. The licensee identified that procedure N-ICS-23A inappropriately required valve RHR-400A be opened. Subsequently, RHR-400A was closed, the ICS fill and vent procedure was terminated, and reactor vessel level was restored using charging pumps. During the event, vessel level decreased to 19.6 percent (12 inches below the flange) and about 300 gallons of reactor coolant were discharged from RHR pump "A" to the containment spray system and into the refueling water storage tank (RWST). The licensee determined that the development and review of procedure N-ICS-23A had not identified procedure errors; specifically, changes in the operating configuration from which the procedure was intended for use versus the plant configuration for which it was actually used were not adequately considered.
Analysis:
The inspectors determined that the inadvertent discharge of 300 gallons ofreactor coolant to the RWST during the fill and vent of the containment spray system because of the use of an inadequate procedure is a performance deficiency warranting a significance evaluation. Using IMC 0612, Appendix B, "Issue Screening," dated November 2, 2006, the inspectors concluded that the finding is greater than minor because if left uncorrected it would become a more significant safety concern in that the use of other inadequate procedures could have rendered inoperable important mitigating equipment, such as the containment spray and residual heat removal systems. Additionally, the finding was associated with the procedure quality and configuration control attributes of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage).
Specifically, the use of the inadequate procedure resulted in the inadvertent drain down of 300 gallons of coolant from the reactor vessel and challenged the configuration of the containment spray and RHR systems. The inspectors evaluated the finding using IMC 0609, Appendix G, "ShutdownOperations Significance Determination Process," dated February 28, 2005, and determined that this finding was of very low safety significance (Green) because it did not require a quantitative assessment. Additionally, the inspectors determined that the finding has a cross-cutting aspect in the area of human performance because the licensee failed to provide complete, accurate, and up-to-date procedures to fill and vent the containment spray system.Enforcement: Title 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, andDrawings," states, in part, that "Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings." Contrary to this, safety-related Procedure N-ICS-23A was inadequate to fill and vent the containment spray system in the existing configuration of the plant and resulted in an inadvertent drain down of the RCS. The licensee entered 13this issue into their corrective action program as CAP038226, "Reactor Vessel LevelDecrease During ICS Fill and Vent." Corrective actions, to date, included significant revision of the procedure and review and approval of the procedure by the Plant Operating Review Committee. Additionally, a root cause evaluation, RCE000741, was in progress that would likely establish additional corrective actions. Because this violation was of very low safety significance and was entered into the corrective action program, this violation is being treated as an NCV (NCV 05000305/2006005-02),
consistent with Section VI.A of the NRC enforcement policy..2Scaffolding in Contact with the Safety Injection System Affects OperabilityIntroduction: A finding of very low safety significance (Green) and an associated NCV ofTS 6.8, "Procedures," was identified by the inspectors for the failure to install scaffolding in accordance with station procedures. Specifically scaffolding was installed inside containment that was too close to, or in contact with, SI system components and piping.
Discussion: On October 23, 2006, while performing a containment closure inspection,the inspectors identified scaffolding that was erected closer than 2 inches from or was in contact with SI components and piping near valve SI-48, "Reactor Vessel Injection Line 1a Vent." Step 4.2.6 of general maintenance procedure GMP-127, "Requirements and Guidelines for Scaffold Construction and Inspection," Revision 0, required a 2-inch clearance or approved engineering evaluation. The inspectors requested a copy of the appropriate engineering evaluation for the installed scaffolding. The licensee determined that one had not been performed and could not be performed because the scaffolding had been disassembled since the inspectors' containment closure inspection. The licensee then interviewed knowledgeable plant personnel in an attempt to determine the configuration of the scaffolding prior to disassembly. From the interviews and a review of a database, the licensee concluded that the scaffolding had been erected too close to multiple safety-related SI components.
Analysis:
The inspectors determined that the installation of scaffolding too close tosafety-related SI components and without an engineering evaluation, contrary to procedural requirements, is a performance deficiency warranting a significance evaluation. Using IMC 0612, Appendix B, "Issue Screening," dated November 2, 2006, the inspectors concluded that the finding is greater than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems (the SI system) that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, improperly positioned scaffolding could have impeded or prevent proper operation of the SI system during an accident.The inspectors evaluated the finding using IMC 0609, Appendix G, "ShutdownOperations Significance Determination Process," dated February 28, 2005, and determined that this finding was of very low safety significance (Green) because it did not require a quantitative assessment. The inspectors also determined that the finding has a cross-cutting aspect in the area of human performance because personnel did not follow the procedure for scaffolding.
14Enforcement: Licensee TS 6.8, "Procedures," Paragraph a., requires that writtenprocedures be established, implemented, and maintained that meet the requirements of Sections 5.2.2, 5.2.5, 5.2.15 and 5.3 of ANSI N18.7-1976. Section 5.2.2, "Procedure Adherence," of ANSI N18.7-1976 specifies that procedures shall be followed. Contrary to this, the licensee failed to follow the requirements of procedure GMP-127 when scaffolding was installed closer than 2 inches from safety-related SI components and no engineering evaluation was conducted. The licensee entered this issue into its corrective action program as CAP038277, "Safety-Related Area Scaffold Not Conforming to GNP-127 for Hot Shutdown Mode." The immediate corrective action was to dismantle the incorrectly installed scaffolding. Planned corrective actions were to modify procedure GNP-127 to better clarify the applicability requirements of the procedure. Because this violation was of very low safety significance and was entered into corrective action program, this violation is being treated as an NCV (NCV 05000305/2006005-03), consistent with Section VI.A.1 of the NRC Enforcement Policy.
1R22 Surveillance Testing (71111.22)
a. Inspection Scope
The inspectors reviewed surveillance testing activities to assess operational readinessand to ensure that risk-significant structures, systems, and components were capable of performing their intended safety function. Activities were selected based upon risk significance and the potential risk impact from an unidentified deficiency or performance degradation that a system, structure, or component could impose on the unit if the condition was left unresolved. The inspection activities included, but were not limited to, a review for preconditioning, integration of testing activities, applicability of acceptance criteria, test equipment calibration and control, procedural use, control of temporary modifications or jumpers required for test performance, documentation of test data, TS applicability, impact of testing relative to performance indicator reporting, and evaluation of test data. As part of this inspection, the documents listed in the were reviewed.The inspectors selected the following surveillance testing activities for review for a totalof three samples (RCS leak detection surveillance, routine surveillance, and inservice testing surveillance):*RCS leak rate weekly checks;*EDG "B" trip testing; and
- SI pump pressure tests.
b. Findings
No findings of significance were identified.
15Cornerstone: Emergency Preparedness1EP2Alert and Notification System (ANS) Evaluation (71114.02)
a. Inspection Scope
Inspectors reviewed and discussed with emergency preparedness (EP) staff proceduresand records on the operation, maintenance, and testing of the ANS in the Kewaunee County portion of the station's Emergency Planning Zone (EPZ) to verify that this ANS equipment was adequately maintained and tested between mid-2004 and mid-2006 in accordance with emergency plan commitments and procedures, and to verify that adequate measures were in place to determine whether siren outages would meet 10 CFR 50.72 non-emergency event reporting criteria. Inspectors also reviewed records of 2004 and 2005 preventive maintenance activities on ANS equipment in Kewaunee County to verify that annual preventive maintenance was completed per procedures.
The inspectors also reviewed a sample of records of non-scheduled ANS maintenance activities conducted between July 2004 and July 2006 to determine whether repairs were initiated in a timely manner following identification of apparent malfunctions. A sample of records were also reviewed to determine if Kewaunee EP staff were effectively using the corrective action program to document and trend siren malfunctions occurring in the Kewaunee County and Manitowoc County portions of the Kewaunee Station's EPZ, although Point Beach Plant EP staff had the lead responsibility for initiating siren maintenance activities within Manitowoc County. The inspectors also reviewed records of twice monthly ANS tests conducted by Kewaunee County officials from July 2005 through June 2006. Using onsite computer equipment, inspectors observed a scheduled test of Kewaunee County's EPZ sirens that was conducted by Kewaunee County officials.These activities completed one inspection sample.
b. Findings
No findings of significance were identified.1EP3Emergency Response Organization (ERO) Augmentation Testing (71114.03)
a. Inspection Scope
The inspectors reviewed and discussed procedures on the improved primary andalternate processes for augmenting the on-shift ERO. The inspectors also discussed the EP staff's improved administrative processes for maintaining the ERO roster and ERO members' contact information, as well as EP staff's ongoing actions to resolve staffing shortfalls for several ERO positions. The inspectors reviewed and discussed ongoing efforts to resolve a licensee-identified inconsistency between the emergency plan and the ERO training program regarding the expected frequency of re-qualification training. Inspectors reviewed records of unannounced off-hours augmentations of the on-shift ERO, which were either call-in drills or were drive-in responses to actual emergency events between March 2005 and April 2006, to determine the adequacy of 16ERO members' performances and the use of the corrective action program onperformance critique items. The inspectors sampled training records of 40 ERO members, who were assigned to key and support positions, to verify that they were currently trained for their assigned positions. The inspectors also reviewed records of training provided to over 100 ERO members on the station's upgraded Emergency Action Level (EAL) scheme that was approved by the NRC and later implemented by the
licensee.These activities completed one inspection sample.
b. Findings
No findings of significance were identified.
1EP4 Emergency Action Level (EAL) and Emergency Plan Changes
a. Inspection Scope
The inspectors reviewed the final summary of the licensee's change management plan,which addressed the mid-2006 re-location of the Emergency Operations Facility and Joint Information Center, from the corporate offices of the former owner of Kewaunee to a Dominion Resources-owned building in Green Bay, Wisconsin. The inspectors then toured these upgraded emergency response facilities. The inspectors reviewed a sample of letters of agreement with off-site support organizations that were listed in Revision 31 of Appendix D of the Emergency Plan to verify that these agreements were adequately detailed and in effect through at least December 2006. The inspectors also reviewed the current memorandum of understanding between the Kewaunee and Point Beach regarding various shared responsibilities for providing training and other assistance to mutual offsite support organizations.The inspectors also performed in-house screening reviews of Revision 31 of theEmergency Plan, Revision A, of the EAL Technical Bases Document, and Revision Y to EPIP-AD-19, which all became effective in late August 2006, and reviewed the licensee's associated pre-implementation evaluations performed per 10 CFR 50.54(q).
Screening reviews of these revisions do not constitute approval of the changes in these revisions and, as such, the changes are subject to future NRC inspection to ensure that the emergency plan, site-specific EALs, and criteria used in offsite protective action recommendation decision making continue to meet NRC regulations.These activities completed one inspection sample.
b. Findings
No findings of significance were identified.
171EP5Correction of Emergency Preparedness Weaknesses and Deficiencies (71114.05)
a. Inspection Scope
Inspectors reviewed Nuclear Oversight (NOS-quality assurance) staff's 2005 and 2006audits of the licensee's EP program to verify that these independent assessments met the requirements of 10 CFR 50.54(t). The inspectors sampled records of EP drills and exercises conducted during 2004 and 2005 to verify that the licensee fulfilled its drill and exercise commitments, and to verify that these activities were adequately critiqued.
Samples of corrective action program records and associated corrective actions were reviewed to determine if concerns identified in the following types of self-assessments were adequately addressed: emergency plan implementation for two actual emergency events; critiques of EP drills and exercises; NOS audits; and the availability of equipment and instrument readouts associated with the EALs.These activities completed one inspection sample.
b. Findings
No findings of significance were identified.1EP6Drill Evaluation (71114.06)
a. Inspection Scope
The inspectors selected emergency preparedness exercises that the licensee hadscheduled as providing input to the Drill/Exercise Performance Indicator. The inspection activities included, but were not limited to, the classification of events, notifications to off-site agencies, protective action recommendation development, and drill critiques.
Observations were compared with the licensee's observations and corrective action program entries. The inspectors verified that there were no discrepancies between observed performance and performance indicator reported statistics. As part of this inspection, the documents listed in the Attachment were reviewed.The inspectors selected the following emergency preparedness activity for review for atotal of one sample:*an operating crew performing an evaluated annual examination simulatorscenario in conjunction with licensed operator requalification training. Drill notifications were simulated with state, county, and local agencies for an alert classification.
b. Findings
No findings of significance were identified.
OTHER ACTIVITIES

a. Inspection Scope
As part of the routine inspections documented in this inspection report, the inspectorsverified that the licensee entered the problems identified during the inspection into the corrective action program. Additionally, the inspectors verified that the licensee was identifying issues at an appropriate threshold and entering them in the program, and verified that problems included in the program were properly addressed for resolution.
Attributes reviewed included: complete and accurate identification of the problem; timeliness was commensurate with the safety significance; evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews were proper and adequate; and classification, prioritization, and focus were commensurate with safety and sufficient to prevent recurrence of the issue.
b. Findings
No findings of significance were identified..2Daily Corrective Action Program Reviews
a. Inspection Scope
To assist with the identification of repetitive equipment failures and specific humanperformance issues for follow-up, the inspectors performed a daily screening of new CAPs. This review was accomplished by reviewing daily CAP summary reports and attending corrective action review board (CARB) meetings.
b. Findings
No findings of significance were identified.
20.3Semi-Annual Trend Review
a. Inspection Scope
The inspectors performed a review of the licensee's corrective action program to identifytrends that might indicate the existence of a more significant safety issue. The review was focused on trending program deficiencies, which considered licensee trending efforts, and licensee human performance results. The inspectors' review nominally considered the period of July through November 2006, with some examples extending beyond those dates when the scope of a trend warranted. The inspectors reviewed adverse trend CAP report items associated with variousproblems that occurred during the period. The review included issues that were documented outside the normal corrective action program, such as major equipment problem lists, repetitive and/or rework maintenance lists, departmental problem/challenges lists, system health reports, quality assurance audit/surveillance reports, self-assessment reports, and maintenance rule assessments. The inspectors compared and contrasted the licensee's trends with those discussed in the licensee's trending documents. Corrective actions associated with a sample of the issues identified in the licensee's trend report or through interviews with licensee management, were reviewed for adequacy. The inspectors focused on those corrective actions pertaining to the trending program. The inspectors also evaluated the report against the requirements of the licensee'scorrective action program as specified in the associated administrative procedure; 10 CFR 50; Appendix B and the commitments made by the licensee in its response to the NRC 2006 Mid-Cycle Performance letter, dated August 31, 2006. Documents reviewed during this inspection are listed in the Attachment to this report.
Assessment and ObservationsThe licensee's Corrective Action Program Performance Monthly Report writtenNovember 9, 2006, rated overall performance as a "significant strength" for the fourth straight month. When licensee management was questioned about this rating by the inspectors, the rating given was much more self-critical. It was stated that the results given in the report were based on older indicator methodology and that the standards were in the process of being raised. While the inspectors noted an increased numbers of CAPs generated and an increased number of CAPs closed, many other improvements that were still needed were found to be early in the process of being implemented.The licensee's Third Quarter 2006 Trend Report, dated November 28, 2006, highlightedthe following as key areas needing improvement: root cause evaluation (RCE)timeliness, a large, increasing backlog of CAP-related activities, and the existence of 314 activities from 2005 or before. The inspectors' review of the 314 older activities revealed 14 had an "A" Significance Level, with the oldest of these being a corrective action to prevent recurrence (CAPR), dated August, 2002, to implement life cycle management as part of RCE000576. In addition, the inspectors noted in the Third Quarter 2006 Trend Report that personnel were not prepared for the work planning 21meetings and were not being held accountable, restating the problems that wereidentified in the previous two quarterly reports.
During the inspection, the inspectors had the following additional observations in thearea of trending and corrective actions:CAP039514 documented a lack of attendees at CAP screening meeting hadoccurred as recently as November 17, 2006, indicative of a lack of commitment by the organization to support the corrective action program as core business.
Interviews with the licensee noted that since that time, screen team participation had increased due to accountability efforts to correct the problem. The inspectors attended a sample of work planning meetings and reviewed a sample of attendance records for recent screen team meetings. While no recent discrepancies were observed due to lack of preparation or not having a quorum present, the representatives who attended these meetings varied significantly.
The inspectors were concerned that without a stable and consistent screen team membership, identification of intra-departmental trends may not be adequate.The inspectors found that "Hot Buttons", the flags currently used for categorizingCAPs, were being eliminated, as evaluated by corrective action CA024639, dated July 10, 2006. Numerous "Hot Button" categories will be replaced with five "Focus on Four" categories (Safety, Human Performance, Equipment Reliability, Corrective Action Program, and Manager/Supervisor Excellence as a cross-cutting category). This change was being made due to excessive "Hot Button" creation and inconsistent implementation which resulted in confusion and minimal trending value. The draft change management plan projects the completion of departmental training, recoding six months of data, and implementation of the new process by February 28, 2007.The inspectors found that the current method of trending, as described on thequarterly trend report cover letters and confirmed in discussions with licensee management, consisted of presenting managers and supervisors with statistically analyzed corrective action program information to share with "appropriate personnel" in their work groups. The appropriate personnel were then expected to identify and correct adverse trends from this information. The licensee found that the results of this process were not meeting expectations and created a change management plan to address corrective action program ownership by the individual departments. Plans were being implemented to revise procedures and train personnel to perform consistent trend analysis in order to create analysts within each department. The draft change management plan projects the approval and completion of departmental training, recoding six months of data, and implementation of the new process by February 28, 2007.The inspectors found that the implementing procedure for Action Requestprocess trending, General Nuclear Procedure GNP-11.08.02, had an incomplete and confusing definition for "Trend - A change in frequency of occurrence of agiven parameter or a change in level of performance of a particular program or organization", along with a reference to the Dominion Trend Analysis Manual for other definitions. The inspectors found that the procedure definition created a 22barrier in recognizing adverse trends by causing the user to focus only onchanging information. For example, a consistently bad level of performance may not be recognized as an adverse trend. A more complete definition from the Dominion Trend Analysis Manual, available on the Dominion web page, briefly discussed how trend data were compared to normal, desired, or historical values and provided criteria requiring further sorting and review. The licensee noted this concern and explained that change management plans included revising this procedure as part of the efforts discussed above.
