==Dear Mr. Crane:==
On December 15, 2006, the U.S. Nuclear Regulatory Commission (NRC) completed aninspection of problem identification and resolution at your Quad Cities Nuclear Power Station,Units 1 and 2. The enclosed inspection report documents the inspection findings which werediscussed on December 15, 2006, with Mr. Gideon and other members of your staff.This inspection was an examination of activities conducted under your license as they relate tothe identification and resolution of problems, compliance with the Commission's rules andregulations and with the conditions of your operating license. Within these areas, theinspection involved selected examination of procedures and representative records,observations of activities, and interviews with personnel. On the basis of the sample selected for review, the team concluded that, in general, problemswere properly identified, evaluated, and corrected. One finding of very low safety significance(Green) was identified during this inspection associated with the effectiveness of the correctiveaction program. The finding involved the failure to develop actions to correct conditionsadverse to quality identified during root cause investigation activities. This finding was alsodetermined to be a violation of NRC requirements. However, because of its very low safetysignificance and because it has been entered into your corrective action program, the NRC istreating this finding as a non-cited violation (NCV), in accordance with Section VI.A.1 of theNRC's Enforcement Policy. If you contest the subject or severity of an NCV in this report, you should provide a responsewith the basis for your denial, within 30 days of the date of this inspection report, to theU.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC20555-0001, with copies to the Regional Administrator, Region III; the Director, Office ofEnforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and theNRC Resident Inspector at the Quad Cities Nuclear Power Station.In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter andits enclosure will be available electronically for public inspection in the NRC Public DocumentRoom or from the Publicly Available Records (PARS) component of NRC's document system(ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (thePublic Electronic Reading Room).

IR 05000254/2006017, 05000265/2006017; 11/27/2006 - 12/15/2006; Quad Cities NuclearPower Station, Units 1 & 2; Identification and Resolution of Problems.The inspection was conducted by region-based inspectors and the resident inspector at theQuad Cities Nuclear Power Station. One finding of very low safety significance (Green) wasidentified which involved an associated non-cited violation (NCV). The significance of mostfindings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter(IMC) 0609, "Significance Determination Process," (SDP). Findings for which the SDP does notapply may be Green or be assigned a severity level after NRC management review. TheNRC's program for overseeing the safe operation of commercial nuclear power reactors isdescribed in NUREG-1649, "Reactor Oversight Process," Revision 3, dated July 2000.Identification and Resolution of ProblemsIn general, the station identified issues and entered them into the corrective action program(CAP) at the appropriate level. In addition, issues that were identified from operatingexperience reports and instances where previous corrective actions were ineffective orinappropriate were also entered into the CAP. The inspectors concluded that issues wereproperly prioritized and generally evaluated well. The inspectors determined that conditions atthe Quad Cities station were conducive to identifying issues. The licensee staff at Quad Citieswas aware of and generally familiar with the CAP and other station processes, including theEmployee Concerns Program, through which concerns could be raised. One finding of very lowsafety significance (Green) was identified associated with the effectiveness of the correctiveaction program. The finding originated from the review of a root cause investigation conductedfor the Unit 1 standby liquid control tank through-wall leak. A.
 
Inspector-Identified and Self-Revealed Findings
 
===Cornerstone: Mitigating Systems===
*
: '''Green.'''
The inspectors identified an NCV of 10 CFR Part 50, Appendix B, Criterion XVI,"Corrective Action," for failure to assure that conditions adverse to quality were promptlycorrected. Specifically, the inspectors concluded that the licensee failed to developactions to correct conditions adverse to quality identified during root cause investigationactivities for a Unit 1 standby liquid control tank leak identified in October 2006. Thisfinding had a cross-cutting aspect in the area of problem identification and resolutionbecause the licensee failed to thoroughly evaluate conditions identified during its rootcause investigation for the SLC tank leakage which resulted in the failure to developappropriate corrective actions. The licensee entered this performance deficiency intothe CAP for resolution.This finding is associated with the Mitigating Systems Cornerstone. The finding wasmore than minor because if left uncorrected, future conditions adverse to quality wouldnot be fully evaluated or corrected. The inspectors assessed the significance of thisfinding as very low safety significance because the finding did not represent an actualloss of safety function of the standby liquid control tank.  (Section 4OA2.a)2Enclosure

Assessment of the Corrective Action Program (1)
Inspection ScopeThe inspectors reviewed documentation for the past 2 years including:  NRC inspectionreport findings, selected corrective action documents, licensee self-assessments,Nuclear Oversight (NOS) audits, operating experience reports and human performanceinitiatives to determine if problems were being identified and entered into the correctiveaction program (CAP) at the proper threshold. CAP implementation, metrics, andstatus, and departmental performance indicators were also reviewed and discussed withthe station staff.The inspectors also reviewed procedures, inspection reports, and corrective actiondocuments to verify that identified issues were appropriately characterized andprioritized in the CAP. Evaluations documented in condition reports (CRs) or issuereports (IRs) were evaluated for appropriateness of depth and thoroughness relative tothe significance or potential impact of each issue. Inspectors attended managementmeetings to observe the assignment of CR categories for current issues and to observethe review of root, apparent, and common cause analyses, and corrective actions forexisting CRs. In addition, the inspectors reviewed past inspection results, selected CRs and IRs, rootcause reports, and common cause evaluations to verify that corrective actions,commensurate with the safety significance of the issues, were specified andimplemented in a timely manner. The inspectors evaluated the effectiveness ofcorrective actions. The inspectors also reviewed the licensee's corrective actions forNCVs documented in NRC inspection reports in the past 2 years.
 
    (2)
AssessmentIdentification of IssuesThe inspectors concluded, in general, that the station identified issues and entered theminto the CAP at the appropriate level. The inspectors' review of operating experiencereports identified that the licensee was appropriately including the issues into the CAP. The licensee has also used the CAP to document instances where previous correctiveactions were ineffective or were inappropriately closed. The licensee performed Common Cause Analysis (CCA) 512702-02 in response to fourstation event free clock reset events that occurred over a 5 month period. The CCAevaluation period was January 1, 2006, through July 31, 2006. The CCA was directedby the plant manager to identify the underlying human performance aspects of the four
 
station event free clock reset events and the balance of human performance issues thathave occurred in the first 7 months of 2006. The CCA was also chartered to look forany underlying latent organizational weaknesses that may have set the stage for theunacceptable level of human performance events. The CCA employed multipleinvestigative tools and a cross-departmental team that included corporate and industryparticipants. The CCA identified two common causes and two organizationalweaknesses. The two common causes were:  1) the misinterpretation of and perceivedrequirements of level 3 "reference use" procedures, and 2) human performance eventswere occurring in all areas, crossing plant operating conditions, work groups andemployee levels. The two organizational weaknesses were:  1) oversight andmanagement challenges along with coding issues for trending and predictive actions,and 2) human performance events were not "emotional" to the site. At severalManagement Review Committee (MRC) meetings, the inspectors observed themembers' sensitivity to identify any issues that could be procedure adherence relatedfrom the review of apparent cause, CCA, or root cause investigation reports. For oneapparent cause, the MRC concluded that the cause was procedure adherence anddirected that the investigation be updated to address procedure adherence. Thereasons for this direction were to document procedure adherence applicability andheighten staff awareness of station human performance issues. In addition, theinspectors attended two review/challenge board meetings held on a root causeinvestigation and a CCA. The review/challenge board initiative was a corrective actionimplemented for the organizational weakness of oversight and management challenge. At each meeting, an appropriate level of challenge was offered to the presenter of theinvestigation. The review/challenge board evaluated the alignment of the proposedcorrective action with the causes that were determined. The review/challenge board isconducted prior to selected investigative reports being presented for MRC approval.An expanded 5 year review was conducted by the inspectors on station electrical cableissues. The initial scope of the licensee's search of the corrective action programdatabase for a 5-year period was approximately 1200 issue reports. From theinspectors' screening, approximately 150 issue reports were selected for further reviewand subdivided into specific categories. Through the inspectors' review of the screenedissue report categories and discussion with licensee engineers, approximately 20 issuereports were selected. The issue statement that was developed for the review was,electro-hydraulic control (EHC) fluid intrusion, primarily into the Unit 2 cable tunnel, andthe subsequent EHC fluid migration into various cable trays and onto power cables.In April 2002, the licensee identified conditions through IR 102044 associated with EHCfluid migration into the Unit 2 cable tunnel. In September 2002, EHC fluid was identifiedthrough IR 122749 as being present in the Unit 2 cable tunnel, in cable trays and oncables lying within those trays. The licensee identified the intrusion pathway asseepage through concrete defects and ceiling cracks within the Unit 2 cable tunnel. Theproposed resolutions were installation of drip pans and/or use of a sealing method torepair the ceiling cracks. The licensee addressed the potential affects of EHC fluid oncables, and identified that the EHC fluid could severely degrade cable insulation overtime. Electric cables, such as those installed at the station, are typically manufacturedwith outer protective jacket covers. The outer jackets are more susceptible to EHC fluiddegradation and were identified as being degraded in a number of station incidents. Allbut the most recently identified damaged outer cable jackets have been repaired. The
 
licensee had implemented a yearly cable tunnel inspection predefine activity 166312-01to monitor for additional cable jacket deterioration and other potential degradedconditions associated with EHC fluid intrusion.In January 2003, an EHC fluid leak occurred above the Unit 2 turbine building 595'elevation that was identified through IR 139980. The licensee questioned the potentiallong-term effect of EHC fluid on equipment and structures. The licensee evaluated thatthere was no degradation of concrete or structural steel from EHC fluid exposure. Theinspectors concluded that in October 2004, the licensee augmented their focus toresolve EHC fluid leaks, and re-analyze the effect of EHC fluid on cables. Additional IRswere generated to further identify areas of EHC fluid intrusion and initiate work orders toaddress intrusion sites and cable jacket repairs. No EHC fluid was found to have comein direct contact with the cable insulation. There was no degradation identified beyondthe protective outer jacket material around any of the affected cables.The licensee has increased the frequency for cable tunnel inspection predefine166312-01 to quarterly through service request 48525. In subsequent licenseeinspections, additional intrusion or seepage into cable trays and/or onto cables has beenidentified. IRs were promptly initiated to correct the deficient conditions identified by theinspections. In addition, the licensee has made the necessary cable repairs in a timelymanner. The inspectors verified that the licensee's cable repairs and drip paninstallations were completed as documented during station walkdowns.Prioritization and Evaluation of IssuesThe inspectors' observations of the Station Ownership Committee (SOC) concluded thatfor some IRs, additional follow-up activities were assigned that extended the time periodfor issue disposition within the organization. None of the issues that were assigned theadditional follow-up resulted in an inappropriate prioritization based on significance. Examples of SOC action taken were to assign work requests, evaluations, and/orcorrective action to specific departmental groups. The inspectors observed the MRCfunction in an oversight role of the SOC. For example, the MRC changed the SOCrecommended action of some issues based on committee dialogue and additionalstation awareness of the issue. The MRC performed grading of investigative CAPproducts to provide feedback on product quality to the sponsoring manager. The IRs that were observed being reviewed by the SOC were also observed beingreviewed by the MRC in their oversight role. Both of the committees functioned well toappropriately characterize and prioritize issues in the CAP. The MRC member dialoguein the review of root, apparent, and common causes was informative, and providedfeedback to the staff on implementing the CAP. The inspectors concluded that issueswere properly prioritized and generally evaluated well.Effectiveness of Corrective Action In general, the licensee corrective actions for the samples reviewed were appropriate,and appeared to have been effective. The inspectors determined that the licenseegenerated IRs when a corrective action was identified which was either inadequate orinappropriate. However, the inspectors developed observations regarding corrective
 
actions that were not properly supported by the documented basis or narrowly focused. The following paragraphs provide examples of these observations.Improper Valve Line-up Results in 1A RHRSW Header LeakThe inspectors noted that for the corrective actions for IR 261135, "Improper ValveLine-up Results in 1A RHRSW Header Leak," a number of extensions were proposedwith no documented basis. The inspectors subsequently determined that the extensionswere appropriate, however, the lack of documentation made the basis for decisionmaking difficult to understand. In addition, the inspectors identified that littledocumentation existed when one of the corrective actions to prevent recurrence wascanceled. The corrective action involved a change to procedure OP-MW-109-101,"Clearance and Tagging."  Again the actions were appropriate, however, the lack ofdocumentation made the basis for decision making difficult to discern.Code Case N-513 Requires Full Circumferential NDEThe inspectors noted that the corrective actions to prevent recurrence, requested by theSOC, for IR 369760, "Code Case N-513 Requires Full Circumferential NDE," werenarrowly focused. The licensee considered the issue a human performancecircumstance, shared the example with the engineering staff, and focused the correctiveaction on the misapplication of the particular code case (N-513). The licensee did notprovide a more general view of misapplication of NDE codes with the engineering staff.Battery Room Heater BackupIR 433852, "Battery Room HVAC Concerns Provided By NRC," identified that portablepan heaters were currently staged in the battery rooms in the event that battery roomtemperature approaches the 65 degree F limit. The station had not yet employed theuse of these portable pan heaters to control battery room temperature. The inspectors'review of QCOP 0010-02, "Required Cold Weather Routines," revealed that the stationdid not consider what would occur from the use of a resistance heater in the potentialpresence of hydrogen. The licensee generated IR 568479 to clarify QCOP 0010-02.

Finding Failure to Develop Corrective ActionIntroduction:  The inspectors identified a Green NCV of 10 CFR Part 50, Appendix B,Criterion XVI, "Corrective Action," for failure to assure that conditions adverse to qualitywere promptly corrected. Specifically, the inspectors concluded that the licensee failedto develop actions to correct conditions adverse to quality identified during root causeinvestigation activities for a Unit 1 standby liquid control tank leak identified in October2006.Background:  On October 12, 2006, Quad Cities Station staff identified a small leak inthe Unit 1 standby liquid control (SLC) tank which resulted in both SLC trains beingdeclared inoperable. Quad Cities requested enforcement discretion for this issue whichwas verbally granted by the NRC on October 13, 2006, and a formal Notice of
 
Enforcement Discretion (NOED) was issued on October 18, 2006. The leak wasrepaired by October 15, 2006. During the discussions for the NOED, Quad Cities staffnoted that potential indications of the leak had been identified in 2004, but theindications were not recognized as a leak through an American Society of MechanicalEngineers (ASME) Code Class 2 boundary until October 2006. The licensee conducteda root cause investigation of this issue.Description:  The inspectors reviewed root cause investigation report 543422-05,"Standby Liquid Control Unit 1 Declared Inoperable Due to Through Wall Leak," datedNovember 20, 2006, to determine if the licensee fully evaluated and corrected thecauses which led to the inoperability of the Unit 1 SLC tank for approximately 2.5 years. The primary scope of this root cause investigation focused on the programmatic andtechnical issues related to the origin of the SLC tank leak identified in IR 543422initiated in October 2006. The scope of the investigation also included IR 224131,"Boron Crystals Forming Near Unit 1 SLC Tank Base Support," initiated in May 2004,and a determination of what programmatic reviews could have identified this conditionearlier including why these reviews failed.The licensee concluded that the programmatic root cause for the incorrect operabilitydetermination of the Unit 1 SLC tank leak was an incomplete application of technicalrigor resulting in incorrect assumptions regarding the ASME code applicability to theUnit 1 SLC tank. These incorrect assumptions were not adequately challenged duringthe condition identification and review process. The licensee also concluded that thetechnical root cause of the Unit 1 SLC tank leak was the grout material used duringoriginal installation of the SLC tank supports contained leachable halogens, that whenwetted, allowed stress corrosion cracking to develop at the grout/tank interface.The root cause investigation report was "approved as amended" at PORC meeting06-33 on December 1, 2006. The inspectors' review of root cause investigation report543422-05 was completed after PORC approval, and also after an Exelon corporatechallenge had been held. The inspectors concluded that the licensee did not fullyevaluate several conditions adverse to quality that were identified during theinvestigation. The licensee's decision to not fully evaluate these conditions resulted inthe failure to develop appropriate corrective actions. The identified conditions were asfollows:Fundamental Practice of Not Validating AssumptionsAlthough the root cause team considered this as part of technical rigor, the team failed to evaluate and develop corrective actions for the behaviors that led to failure to validatethe assumption that the tank was not a code component during the prompt operabilityprocess. The validation of assumptions during the prompt operability process is criticalto ensuring continued plant safety and the effectiveness of the corrective actionprogram.
 
Shift Manager Inappropriate ActionThe investigation focused on the shift manager who inappropriately declared the SLCtank operable in May 2004 rather than evaluating the implementation of the promptoperability process by all shift managers. As such, the licensee did not fully determinethe extent of condition of inappropriate operability determinations using the promptoperability process. Because the licensee did not fully analyze the implementation ofthis process by the end users (the shift managers), the licensee was unable to identifyand correct potential problems in this area.Shift Manager Recommendation Results in "C" Priority WorkThe root cause investigation report identified that the shift manager recommendedadditional NDE to be performed during the next work week as part of his May 2004operability review of IR 224131. The root cause investigation report also identified thatthe NDE related work order was still in planning as of October 2006. However, noevaluation was provided as to whether the decision to not perform the work requestedby the shift manager was appropriate. In addition, there was no evaluation regardingthe process used in determining that the work recommended by the shift manager wasnot needed. System Engineer Decision After Communicating With Dresden PeerDuring conversations on October 11, 2006, the Dresden system engineer discussedwith the Quad Cities system engineer that the SLC tank may be an ASME Class 2system boundary. The fact that the SLC tank leakage compromised an ASME CodeClass 2 boundary was not identified by the Quad Cities system engineer until thefollowing day, October 12, 2006. The root cause investigation developed a time line ofevents that described the communications that occurred between the Quad Cities andDresden system engineers. The inspectors discussed with the Quad Cities engineer theinformation that was exchanged and the reasons for not pursuing any action the night itwas provided. The Quad Cities system engineer provided two reasons for not pursuingthe code related information. First, he believed that the SLC system would haveperformed its function during an ATWS event. Second, he believed that there was avery low probability that the Dresden system engineer was correct regarding the factthat the SLC tank was a code component. The root cause investigation did not evaluatethe system engineer's decision to determine whether or not it was appropriate.Chapter 16 of the licensee's Quality Assurance Topical Report defined conditionsadverse to quality as failures, malfunctions, adverse trends, deficiencies, deviations,defective material, design errors, equipment, and nonconformance to specifiedrequirements. Based upon the examples provided in the licensee's Topical Report, theinspectors concluded that the deficiencies in the root cause evaluation processdiscussed above constituted a failure to properly evaluate and resolve identifieddeficiencies. This issue was determined to be a performance deficiency.
 
=====Analysis:=====
The inspectors concluded that the performance deficiency was more thanminor because if left uncorrected, future conditions adverse to quality would not be fullyevaluated or corrected. The inspectors reviewed Appendix B to Inspection ManualChapter 0612 and determined that this finding was required to be evaluated by theSignificance Determination Process due to its impact on the Mitigating SystemsCornerstone objective of ensuring the operability, availability, reliability, or function of asystem that responds to initiating events to prevent undesirable consequences. Theinspectors assessed the significance of this finding as very low safety significance(Green) because the finding did not represent an actual loss of safety function of theSLC tank. This finding had a cross-cutting aspect in the area of problem identificationand resolution because the licensee failed to thoroughly evaluate conditions identifiedduring its root cause investigation for the SLC tank leakage which resulted in the failureto develop appropriate corrective actions.Enforcement:  10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," states, inpart, measures shall be established to assure that conditions adverse to quality arepromptly identified and corrected. Contrary to the above, the licensee failed to promptlycorrect several deficiencies identified in root cause investigation report 543422-05. Because this failure to comply with 10 CFR Part 50, Appendix B, Criterion XVI, is of verylow safety significance and has been entered into the licensee's corrective actionprogram as IR 569581, this violation is being treated as an NCV, consistent withSection VI.A of the Enforcement Policy (NCV 05000254/2006017-01;05000265/2006017-01). Corrective actions for this NCV include licensee review of theNRC issues and the root cause investigation report, and a determination as to whetherto revise the root cause investigation. The licensee subsequently prepared asupplement to the root cause investigation report. In addition, the corrective actionprogram will review this NCV for lessons learned.

Assessment of the Use of Operating Experience (1)
Sin ce r ely,/RA/
Inspection ScopeThe inspectors reviewed the licensee's program for handling operating experience(OPEX). Specifically, the inspectors reviewed the implementing procedure, attendedcorrective action program meetings to observe the use of OPEX, reviewed OPEXevaluated by the station and reviewed selected 2006 monthly assessments of the OPEXcomposite performance indicators. The inspectors conducted a NRC OPEX search on EHC events resulting in thecollection and review of IE Circular No. 77-06, "Effects of Hydraulic Fluid on ElectricalCables," licensee event reports, inspection report findings and international incidentreports.

In general, OPEX information was being well utilized at the station. The inspectorsobserved that Exelon fleet internal and industry OPEX on several occasions wasdiscussed by SOC and MRC members to support review activities and corrective actionprogram investigations. During licensee staff interviews, the inspectors identified thatthe use OPEX was being consider during daily activities.The licensee performed Nuclear Oversight (NOS) Audit NOSA-QDC-05-01 of the CAPin May 2005. The audit was performed to meet the audit requirements of 10 CFRPart 50, Appendix B, and the Exelon/AmerGen Quality Assurance Topical Report. Theaudit team incorporated industry OPEX by reviewing issues that have been recentlyidentified as a result of NRC problem identification and resolution inspections. Inaddition, fleet-wide issues identified by audits at other Exelon sites (i.e., lessons learnedOPEX), resulted in five common deficiencies and five common enhancements beingidentified during this audit. However, the inspectors developed observations regarding some OPEX that was notreviewed or properly screened for applicability. The following paragraphs provideexamples of these observations.IE Circular No. 77-06, "Effects of Hydraulic Fluid on Electrical Cables" The NRC Office of Inspection and Enforcement document, IE Circular No. 77-06,"Effects of Hydraulic Fluid on Electrical Cables," issued in April 1977, advised licenseesof the potential affects of EHC Fluid when in contact with specific types of insulatedelectrical cables. The IE Circular stemmed from detailed correspondence from thelicensee to the NRC in April 1976 in response to NRC Inspection ReportNo. 050-265/76-04. The report described in detail the migration of EHC fluid to theUnit 2 Cable Tunnel and onto electrical cables that were located within the cable trays. The report also described actual degradation of nuclear instrumentation cables and theresultant cable splice repairs. The EHC fluid manufacturers that were consulted statedthat cables jacketed with Polyvinylchloride (PVC) were severely affected by EHC fluid. Therefore, such cables were not recommended for use around EHC fluid. If the stationstaff would have conducted a review of this IE Circular in 2002, the station would havegained a valuable historical perspective from their own OPEX information. This wouldhave supported a more informed recognition and response to EHC fluid intrusionevents.Corrective Action Program Investigation OPEX ApplicabilityThe inspectors reviewed the use of OPEX in root cause investigation report 543422-05,"Standby Liquid Control Unit 1 Declared Inoperable Due to Through Wall Leak."  Therewere two NRC findings reported during 2005 that were discounted as being applicableduring the root cause investigation. The first was the misapplication of an ASME codecase in evaluating a RHRSW pump through wall piping leak. This was discountedbecause the event involved ASME Class 3 piping instead of ASME Class 2. The secondwas the failure to document assumptions and engineering judgment as part of anoperability evaluation. This was discounted because the event documented a deficiencythat occurred on an operability evaluation rather than a prompt operability decision. The

Assessment of Self-Assessments and Audits(1)  Inspection ScopeThe inspectors reviewed selected focused area self-assessments (FASA), check-in self-assessments and NOS audits of the corrective action program, engineering designcontrol, maintenance and engineering programs. The inspectors evaluated whetherthese audits were being effectively managed, were adequately covering the subjectareas, and were properly capturing identified issues in the CAP. In addition, theinspectors also interviewed licensee staff regarding the implementation of the audit andself-assessment programs.(2)  AssessmentNo findings of significance were identified.The inspectors concluded that the self-assessments and NOS audits were generallycritical and probing. Outside resources were utilized, when appropriate, to gain anindependent perspective and to include non-site OPEX in the process review. Therewere a number of deficiencies, recommendations and strengths identified across thespectrum of performance, including issues of improper CAP implementation. Asappropriate, the self-assessment and NOS audit deficiencies were documented in theCAP. The licensee performed Check-In Self-Assessment 328946, "Corrective Action ClosureReview," in May 2006. The self-assessment conducted a review of 33 corrective actions(CA) out of a total of 343 CAs that were completed in October or November 2005. TheCAs were reviewed using the criteria of LS-AA-125, "Corrective Action ProgramProcedure," Revision 9. The self-assessment determined if the assignment wasadequately written, if the response would stand alone, and if the closure guidance wasmet. Seven CAs were considered to have inadequate closure. These inadequateclosures involved four departments. The self-assessment documented the CAdeficiencies in the CAP through IR 491685.The licensee performed Check-In Self-Assessment 445362-03, "Operator WorkaroundProgram," in February 2006. Over the past 3 years, the Quad Cities station had thehighest average number of operator workarounds (OWAs) Exelon fleet-wide. Thestation implemented various strategies to improve OWA closure. In June 2003, theexpectation was established that IRs would be initiated any time an OWA or operatorchallenge (OC) schedule milestone date was extended or not met. The number of IRswritten for extended or missed milestone dates were 18 in 2003, 14 in 2004 and 5 in2005. The self-assessment concluded that the data showed there had been asignificant increase in accountability for meeting scheduled commitment dates of OWAsand OCs.

Assessment of Safety-Conscious Work Environment(1) Inspection ScopeThe inspectors interviewed the Quad Cities station staff to determine if there were anyimpediments to the establishment of a safety conscious work environment. In addition,the inspectors discussed the implementation of the Employee Concerns Program (ECP)with the ECP Coordinators. Licensee programs to publicize the CAP and ECPprograms were also reviewed. In addition, FASA 513091 conducted on the correctiveaction program in October 2006, was reviewed for ECP issues.(2) AssessmentNo findings of significance were identified.The inspectors determined that the conditions at the Quad Cities station were conduciveto identifying issues. The staff was aware of and generally familiar with the CAP andother station processes, including the ECP, through which concerns could be raised. Staff interviews identified that issues can be freely communicated to supervision, andthat several of the individuals interviewed had previously initiated IRs. In addition, areview of the types of issues in the ECP indicated that site personnel were appropriatelyusing the corrective action and employee concerns programs to identify issues. Theinspectors interviewed the ECP Coordinators, and concluded that the individuals werefocused on ensuring all site individuals were aware of the program, comprehensive intheir review of individual concerns, and used the corrective action and employeeconcerns programs to appropriately resolve issues.The corrective action program FASA, 513091, identified an ECP deficiency. Thespecific deficiency was that the communication of the ECP needs to be refreshed,particularly among new engineers. The licensee generated IR 545057 to document thisdeficiency. The staff identified that previously, a signature line existed on the station'sorientation checklist for all newly hired employees to meet with an ECP representative todiscuss the program. However, the station adopted a corporate generated orientationprocedure which eliminated the ECP signature line item.
