Section 1 Assessment Results and Conclusions 1.1 Executive Summary The Engineering Programs Independent Assessment Team found the engineering programs at Davis-Besse (DB) to be effective overall, and found performance in each of the six areas designated for assessment to be effective.
The team reviewed engineering work products in a number of areas in depth, and did not find any discrepancies that were considered to be either significant in terms of the validity of the work product, or indicative of a systematic deficiency in engineering work performance or quality management.
Findings were categorized into three types, defined as an Area of Strength (AS),
an Area for Improvement (AFI), or an Area in Need of Attention (ANA):
An Area of Strenqth is an identified performance, program, or process element within an area of assessment that is significant in obtaining desired results.
An Area for Improvement is an identified performance, program, or process element within an assessed area that requires improvement to obtain the desired results with consistency and effectiveness. All Areas for Improvement identified in the Assessment Report will be addressed by the Action Plan@) submitted to the NRC.
An Area in Need of Attention is an identified performance, program, or process element within an area of assessment that, although sufficient to meet its basic intent, management attention is required to achieve full effectiveness and consistency. Areas in Need of Attention are not addressed by Action Plan@)
submitted to the NRC, but are considered for entry into the Corrective Action Program.
2007 Findings The Teams findings in 2007 consisted of:
0 Areas of Strength (AS) 0 Areas For Improvement (AFI) 5 Areas in Need of Attention (ANA)
Page 2
The five Areas in Need Of Attention (ANAs) identified in 2007 are designated as:
1 ANA Waivers of Design Interface Evaluation (DIE) Reviews 2 ANA Equipment Reliability (ER) Program - Forecast of Preventive Maintenance (PM) Strategy Workload, Single Point Vulnerability (SPV) Analysis 3 ANA -
System Health Activities Plant Computer, 480 V AC, Radiation Monitors 4 ANA Analysis of Process-Related Weaknesses 5 ANA Assessment Strategy and Implementation These findings are described in section 1.5.4 of this report.
By comparison, the teams findings in 2006 consisted of:
2 Areas of Strength (AS) 0 Areas For Improvement (AFI) 7 Areas in Need of Attention (ANA)
Strengths The Team did not identify new strengths in Engineering Programs this year.
However, the Team reviewed the strengths identified in 2006, 1 AS DIE Process and 2 AS Margin Management, the strengths identified in 2005, 1 AS Improved Engineering Performance and Environment, and in 2004, (1 AS) Rapid Response Team Effectiveness in Supporting Resolution of UrgenVEmergent Issues, Especially As Needed By The Plant, (2 AS) Internalization Of Engineering Principles And Expectations, and (3 AS) Engineering Assessment Board Influence On Quality Of Engineering Work Products. All these previously identified strengths continue in 2007.
Overall Conclusions The Independent Assessment Team made several overall conclusions from the 2007 Assessment:
Davis-Besse Engineering Programs continue to be effective in both technical and organizational aspects.
Improvements have been noted over the four annual assessments. DB Engineering has addressed problems, often self-identified, and has improved performance in technical quality of engineering work products and in throughput of engineering work processes.
Page 3
The nature of work observed has transitioned from post-restart backlog reduction + steady state plant support to predominantly steady state plant support. The resources made available from reduction of backlog work have been utilized to reduce the amount of engineering work contracted outside the Company and by increasing the effort for improvement items, e.g. PM Strategy development.
Condition Reports (CRs) written during the assessment Five CRs were written during the assessment:
CR 07-26522 NORM-ER-3103-D Rev.3 Does Not Indicate Replacement Frequency The PM template for breakers does not contain a replacement task and frequency for molded case circuit breakers. The June 24, 2004 Technical Bulletin TB-04-03 indicates the life of Westinghouse supplied molded case circuit breakers for mild environment applications is 20 years.
CR 07-26574 COIA-ENG-2007 - C-EE-02.01-010-Rev 30 (DC Calc) Addendum A03, Calculation Error Plant staff noted an error in the application of calculation assumption 2.5 related to the percentage of solenoid loads to be considered in relay panels. The assumption specified the use of 67% of the solenoid loads while the calculation had actually used 100%. This error did not adversely affect the conclusions and a Post-It-Note initiated to correct the error in the next revision. Discussion with plant staff determined that a Condition Report should have been initiated to document this error. Correction of errors, even though in the conservative direction, is outside the purpose of a Post-It-Note. This CR was initiated to document the calculation error.
CR 07-26779 COlA ENG 2007 - NNI Module Not Included for Calibration Under PM 4222 PMA DB-REV-06-0048 requested a revision to NNI PM 4222 to incorporate calibration of seven NNI modules associated with the Reactor Pressure Control String. This was a corrective action associated with resolution of CR05-05988. The PMA was rejected because the modules were thought to be included in another PMA, 05-1184. However, Memory Module 3-8-9 had not been included in PMA DB-REV-05-1184, and therefore the corrective action would not have been fully implemented.
CR 07-27185 COIA-ENG-2007 Snapshot Self Assessment Not Finalized In preparations for the NRC Inspection on the Heavy Load Control of Reactor Vessel Head, a Snap Shot Self Assessment was performed Page 4
during the first part of July 2007. Self Assessment number DB-SA 068 has been assigned to this activity. To date, the self assessment report has not be written. NOBP-LP-2001 does not specify a time the report needs to be completed. However, it is recognized that the longer the time between the completion date and the final report date, the greater the potential of not being able to capture all of the applicable information.
CR 07-27389 COlA ENG-2007 - AOV Program Self Assessment Implementation Not Evaluated The AOV program tri-annual performance assessment was performed by participating on a snapshot assessment team at Beaver Valley. While the general aspects of the fleet AOV program procedure and practices could be evaluated there, the team could not find any evidence from interviews and document review that the implementation aspects of the program at Davis-Besse were thoroughly assessed Page 5
1.2 Introduction The Confirmatory Order Modifying License dated March 8, 2004, required FENOC to conduct independent assessments of the effectiveness of the engineering program annually for a period of five years. The assessment conducted by the Independent Assessment Team and reported in this document is the fourth annual independent assessment of the engineering program.
The plan for this Independent Assessment was formulated in accordance with the guidance of FENOCs procedure DBBP-VP-0009 Management Plan for Confirmatory Order Assessments Rev 3 effective 12/2/2005, and also with benefit of the guidance of FENOCs procedure NOBP-LP-2001 FENOC Self AssessmenVBenchmarking Rev 9 effective 10/10/2006. The Assessment Plan was submitted to the USNRC via serial letter 1-1495 dated June 12, 2007 (see Appendix 2)
The members of the Independent Assessment Team were drawn from the nuclear power industry. There were three team members from operating US nuclear plants and three from the Marathon Consulting Group. The resumes of the team members are included in the Assessment Plan and also presented in Section 1.7 Resumes of this report. The Team members were:
John Garrity The Marathon Consulting Group, Team Leader Paul Borer The Marathon Consulting Group Harold Baumberger The Marathon Consulting Group Rod Filipek St. Lucie Nuclear Power Plant, FPL Mark Flaherty Calvert Cliffs Station, Constellation Nuclear Joseph Pechacek JA Fitzpatrick Nuclear Power Plant, Entergy
- Left during week due to unanticipated home station duty requirements The Independent Assessment Team commenced work on the Davis-Besse (De) independent assessment during the week of June 25, 2007, with information gathering activities and discussions with FENOC management. The team gathered information from FENOC relevant to the DB assessment and posted this information to an Internet FTP site established for this purpose over a period of several weeks. The weeks of August 20 and August 27 were devoted to intensive review of FENOC documents and formulation of interview strategies, questions, and interview lists. The Team spent the weeks of September 10 and September 17 at the Davis-Besse site conducting initial and follow-up interviews and reviewing additional FENOC supplied material.

- d. Determine if the Engineering staff is aggressive in correcting self-assessment and assessment findings, and determine whether the corrective actions are adequate, timely, properly prioritized, and that effectiveness reviews are ensuring the desired results.
- e. Determine the receptivity and responsiveness of management and staff to issues raised in self-assessments and assessments.
6 . Corrective actions taken in response to the Areas in Need of Attention (ANAs) identified during the 2006 Independent Assessment of the Davis-Besse Engineering Program Effectiveness The Assessment Team will evaluate the responses to the seven (7) Areas in Need of Attention (ANAs) identified during the 2006 Independent Assessment:
1 ANA Inattention to detail in calculations 2 ANA Implementation of requirements from calculations 3 ANA Equipment Reliability Program 4 ANA Red plant health systems 5 ANA ECP Revision Reviews 6 ANA Follow-ups to assessments and last year's COIA-ENG- 2005 7 ANA Management of engineering workload Page 9
1.4 Methodology The assessment was performed in accordance with the sequence of steps, summarized below. These steps were developed in preparation for the 2004 COlA of engineering programs and have been utilized in each successive assessment.
- 1. Develop the assessment scope, including areas to be assessed and assessment topics under each area. This step included consideration of FENOC management's views, FENOC's procedural and business planning guidance for assessments in general, and the need to meet the particular assessment requirements for Davis-Besse.
- 2. Develop the assessment plan, including the overall objectives and approach, the framework for conducting the assessment, and including review and comments by FENOC engineering and corporate management and staff.
- 3. Determine the team size and composition requirements
- 4. Recruit the team, including industry peers.
- 5. Develop a document library and means to provide access to team members.
This included collecting documents from FENOC's corporate offices and the Davis-Besse site such as procedures, performance reports, engineering work products, and organizing them for access by team members through a website established for this purpose.
- 6. Develop a list of plant personnel to be interviewed and typical interview questions or areas of inquiry. A list of plant personnel to be interviewed was developed by defining the organizational positions to be interviewed for each assessment area and topic, and selecting one or more team members to represent that interview area of interest.
- 7. Develop the detailed interview schedule. Plant administrative support personnel scheduled interviews and published schedules notifying interviewees and team members of the time, date, location, subject, and participants of each interview. Typically an interview was scheduled for an hour, and interviewees were scheduled to meet with from one or two Team members. Follow-up interviews were scheduled during the assessment as needed. Approximately sixty formal interviews were conducted, with approximately sixty different individuals interviewed, and additional follow-up discussions were held as necessary. The first week on site was dedicated to interviews and assessment of the areas of modifications, corrective action program use by engineering, and system engineering, while the second week focused on the areas of calculations, effectiveness of assessment activities, Page 10
and corrective action taken in response to ANAs identified in the 2006 independent assessment.
- 8. Assemble the team and provide orientation. The team assembled for an orientation session the Sunday evening before the assessment. The interview schedules were briefed, any new documents received were noted, and the overall assessment schedule was discussed. The assessment plan and scope, the background for and development of the assessment scope, and the guidance provided for focused self-assessments by the FENOC fleet procedure, were discussed.
- 9. Obtain badges for unescorted access to the plant.
10.Conduct interviews and document reviews. During the assessment period, results of interviews and document reviews were summarized on daily records of facts and observations. Items of interest were those thought to require further follow-up or having the potential for becoming findings. The daily records were collected, consolidated, and distributed to team members on a daily basis.
11.Organize items of interest. Toward the end of each of the assessment weeks, items of interest from daily records were binned to identify evolving issues in the form of potential Areas of Strength, Areas For Improvement, and Areas in Need of Attention in each of the assessment areas. Potential findings were documented.
12.Provide regular counterpart briefings. The Team briefed site counterparts on a regular basis to keep the site staff informed of items of interest and potential findings, and also to support generation of Condition Reports when appropriate (five were generated during the assessment) 13.Consolidate items of interest into Areas of Strength (AS), Areas for Improvement (AFls), and Areas in Need of Attention (ANAs). Near the end of each assessment week, issue summaries were developed to reflect available information and to support generation of management briefing and exit talking points.
- 14. Brief plant engineering management at exit. Site management was briefed at a formal exit on Friday of the second week of the assessment. FENOC key corporate, site, and engineering personnel were included in this briefing. The briefings were conversational in style, with a team member for each assessment area discussing the significant findings in his area. For each potential finding, the issue and appropriate examples or other supporting information was presented and questions were answered. The daily counterpart briefings and management pre-exit briefings assured that the site personnel being briefed already knew of all findings and that appropriate CRs had been generated.
Page 11
- 15. Provide assessment preliminary findings. Site management briefing summaries and talking point outlines were provided to FENOC in electronic file form after the assessment was complete. (At this stage, the findings were still considered draft, but useful information for FENOC).
- 16. Provide report for Davis-Besse. This report is the report for information and action by Davis-Besse and FENOC.
Page 12
1.5 Conclusions The Assessment Team's conclusions are summarized in this section. These findings are based on extensive working field notes and Team discussions conducted each day during the assessment period and after.
1.5.1 Overall Rating of Engineering Programs Effectiveness The Independent Assessment Team rates the effectiveness of Engineering Programs as Effective, with no identified Areas for Improvement and several Areas in Need of Attention.
Davis-Besse Engineering Programs continue to be effective in both technical and organizational aspects.
0 Improvements have been noted over the four annual assessments. DB Engineering has addressed problems, often self-identified, and has improved performance in technical quality of engineering work products and in throughput of engineering work processes.
The nature of work observed has transitioned from post-restart backlog reduction + steady state plant support to predominantly steady state plant support. The resources made available from reduction of backlog work have been utilized to reduce the amount of engineering work contracted outside the Company and by increasing the effort for improvement items, e.g. PM Strategy development.
Specific findings in the 2007 independent assessment included 0 Areas of Strength (AS) 0 Areas For Improvement (AFI) 5 Area in Need of Attention (ANA) 1.5.2 Assessment Ratings by Assessment Areas This Section (1.5.2) presents the Independent Assessment Team's conclusions about the effectiveness of Engineering performance in each of the six assessment areas.
The System Engineering area had two ANA findings. There was one ANA finding in each of the Calculations, Corrective Action Program, and Assessments areas. There were no findings in the Modifications and the Follow-Up to 2006 assessment areas. All the Findings are described in section 1.5.4, and those descriptions are referenced under the heading "Findings for This Area" in the discussion of each of the six assessment areas.
Page 13
Each of the five findings for 2007 related to a single assessment area, Le. there were no cross-cutting findings (findings applicable to more than one area). In the 2006 assessment, four (4) findings were considered cross-cutting findings applicable to two or more areas.
The distribution of Findings between unique and cross-cutting has changed since last year when four of the ANA findings were considered cross-cutting. (In 2005 only one Finding was unique and five were cross-cutting.) This indicates that the assessment findings are becoming less systemic within the Engineering organization. This supports the team's assessment that the Engineering department continues to improve and issues are becoming more isolated.
1.5.2.1 Modifications Area Effectiveness Rating Overall, the team rated the modification process Effective. This is based on the quality of ECPs, interviews with engineers and managers, and Engineering Assessment Board (EAB) performance indicator trends.
There are no Findings associated with this area. The Engineering organization continues to produce quality modifications. The finding from the 2004 COIA, Modification Tracking and Closeout, continues to be addressed and further improvement in the reduction of the backlog of open modifications was noted.
The number of open modifications has been reduced. The milestone for the issuance of all modifications one year prior to the 15'h refueling outage was met.
This allows sufficient time for outage and installation planning and should help increase modification effectiveness.
Source Information The Independent Assessment Team conducted interviews of selected Engineering and Site personnel and reviewed selected documents from the reference library (See Sections 1.6.1 & 1.6.2).
The team reviewed selected Engineering Change Packages (ECPs), interviewed design and system engineers and managers, fleet oversight staff, and the EAB member.

There are about 17 major modifications scheduled for the 15'h refueling outage, and all ECP packages were produced one year before the original outage start date.
The use of outside vendors to develop modification packages or to produce calculations has been greatly reduced in 2007. As a result, the past issue of dealing with vendor quality problems in the acceptance process is not causing quality issues this year.
Several ECP packages were reviewed, focusing on descriptions, 10CFR50.59 screens, regulatory applicability determinations, and various design interface documents. The assessment team concluded the technical content of ECPs and associated documents was acceptable.
The EA6 Quarterly Report for the period April 1 through June 30, 2007 was reviewed. The report results were then discussed with the responsible Engineering managers. EAB review scope includes all ECPs and associated calculations, selected 50.59 evaluations and selected Operability Evaluations.
The EAB evaluated 67 products during this period, and have documented a sideways trend in FENOC design engineering product quality. The EAB grades continue to be satisfactory, but below the station stretch goal. Common quality problems identified by EAB are the lack of clear articulation of the problem setup and lack of clearly defined assumptions. The EAB does participate in quarterly engineering department continuing training to share lessons learned. Action has been taken to address in-house and vendor quality issues in the past COIAs.
Vendor usage by the design department has been minimal, with only four vendor documents reviewed by the EAB.
The number of Engineering Change Process documents in Design Engineering is now about 300, compared to about 500 in early 2006, about 700 in early 2005, and about 900 in early 2004. The total engineering backlog is actively tracked and has been reduced by about 400 items in 2007, with a current population of about 1170 items.
Page 15
The modification closeout process was reviewed to ensure timely drawing and record updates. Currently there are approximately 17 packages in the closeout process. The modification closeout process has improved over the past three years and is keeping this backlog to a manageable level.
The list of temporary modifications was reviewed to ensure plans were in place to remove them during the next refueling outage. Current plans are to exit the outage with only two temporary modifications in place.
There is a strong commitment to proactively address staffing issues that will occur due to retirements over the next few years. The department has hired or plans to hire several engineers in 2007 and 2008. There is also a strong engineering co-op student program with a local university, which is the source of several new hires. The director has authorization to increase his headcount over baseline in 2008 to accommodate the new hires. There are also plans to supply seven SRO candidates from engineering over the next four years. These candidates will eventually fill key engineering or plant staff positions.
Specific Issues for This Area None Findings for This Area None Cross Cutting Findings Applicable to This Area None CRs issued during assessment of this area None 1.5.2.2 Calculations Area Effectiveness Rating Overall the team rated the calculation area as Effective based on the quality of work products reviewed and the continuing progress being made. Backlogs have been lowered near target levels in plant engineering and technical services engineering, and continue to improve in design engineering.
Source Information Page 16
The Independent Assessment Team conducted interviews of selected Engineering and Site personnel and reviewed selected documents from the reference library (See Sections 1.6.1 and 1.6.2).
In particular, the team reviewed the plant Design Basis Assessment Reports (DBAR), with emphasis on the Calculation Health and Calculation Quality sections, Condition Reports related to calculations, and a sample of new and revised staff and vendor calculations issued since the last assessment.
Interviews were conducted with engineers related to the work products reviewed.
Finally, the team independently reviewed thirteen calculations performed since last year for conformance to standards and expectations with respect to technical rigor.
Calculations reviewed included:
C-EE-002.01-010, Rev 30, DC Calc - Battery and Charger Sizing, Short Addendum A03 Circuit, and Voltage Drop C-EE-002.01-010, Rev 30, Addendum A02 C-EE-002.01-010, Rev 30 C-EE-015.03-008, Rev 4, AC Power Systems Analysis Addendum A14 C-EE-015.03-008, Rev 4, Addendum A28 C-EE-015.03-008, Rev 4, Addendum A29 C-ME-011.01-141, Rev 1 Service Water System NPSH Analysis C-ME-040.01-004, Rev 0 Boric Acid Addition Tank Vortex Formation

Follow up was performed related to one CR that appeared to have implications related to the effectiveness of the design review process:
CR 07-24820 identified an error in the methodology and calculation of allowable stresses for determining the acceptability of a pipe patch to be welded to a Closed Cooling Water pipe. The methodology error involved the failure to include a 1.5 stress intensification factor and the use of an incorrect formula for allowable shear stresses. The calculation error involved the incorrect calculation of a seldom-used trigonometric function. The above errors were not caught during the design review, and ultimately were identified by a Nuclear Regulatory Commission inspector. This CR was thoroughly investigated and determined to be due to a human performance error resulting from a lack of questioning attitude. The team interviewed the design reviewer to understand the causes of the failures noted. The team concluded that, although errors were made, the design review process was adhered to and appears sound.
0 .
The errors identified in the CRs noted above are considered to be isolated and not indicative of adverse trends in calculation rigor and quality. Plant staffs Page 18
identification of the error in the DC Calculation is a noteworthy example of the application of a questioning attitude while updating a calculation.
The quality of calculations is also monitored by using Engineering Assessment Board (EAB) scores presented in the DBAR Calculation Quality Section. EAB scores show a mixed trend since last assessment with declining performance (rising scores and above the goal of 1.O) in the last quarter of 2006 and with 2007 scores generally lower and below goal (August 2007 year-to-date average of 0.57), but overall not achieving scores as good as the last assessment period (late 2005 and first half of 2006).
The EAB Fourth Quarter 2006 Report noted:
The Twelve Week Rolling Average Scorefor all products reviewed by EAB had been less than or equal to 0.5for every month since November of 2004, until this quarter.
The average score this quarter was 0.98. Potential contributing causesfor this decline may be attributed to:
- 1. A learning curve by new design personnel.
- 2. NOBP-CC-2005 EngineeringAssessment Board was implemented at Davis-Besse on 9/6/06,. This is a fleet wide businesspractice for implementation of EAB.
The grading criteria contained in this business practice are different than the grading previously used.
- 3. Many of the modifcation packages and calculations which are required to support 15RFO were provided to EAB for review this quarter. These packages were prepared to meet deadlinesfor issue. Time pressurefor issuance of these packages may be part of the reason forpoor quality.
- 4. EAB has waived review of many of the more simple, non-safety packages which previously had been reviewed. This affects the average since before these would likely have received a good grade and helped the average.
Condition Report 07-13550 has been initiated to evaluate and determine any corrective actions to the declining EAB scores.
The Apparent Causes of CR 07-13550 were determined to include (1) more stringent fleet-wide grading criteria, (2) inadequate use of human performance tools and (3) unclear guidance for design input parameters. Corrective actions are addressing human performance issues and guidance for design inputs. The assessment team examined this area and concurs with the Davis-Besse analysis and actions.
EAB scores in 2007 have improved from the 0.98 score of the fourth quarter of 2006, and the 2007 year-to-date average is 0.57 through the first eight months.
Although the scores remain above the pre-4Ih quarter 2006 scores of between 0.2 and 0.4, the differences are judged to attributable to a change in the grading criteria, and not indicative of a decline in performance.

Overall, it is concluded that the calculation area has made continued progress since the last assessment. The technical rigor of calculations has remained excellent. Findings noted represent opportunities to improve and are not considered significant weakness or shortcomings.
Specific Issues for This Area The following observations are provided for consideration. None of these rose to the level of a finding:
0 Filenet search results for calculations list Addenda and Post-It-Notes from previous revisions that have already been incorporated in the current Revision. In some calculations, this can produce a long list of Addenda and Post-It-Notes that may have to be reviewed to determine all changes to the current calculation.
Consideration should be given to statusing incorporated Addenda and Post-It-Notes as superseded or add a note: Incorporated into Revision xx.
0 Several cases were noted where changes to System Descriptions to add information or update design parameters as the result of revised calculations were considered enhancements. The policy System Descriptions is for use as a roadmap or tool, but not as the definitive reference for design basis information. It is the teams opinion that treating System Description impacts as enhancements may send a message that they are low priority. Keeping the descriptions up-to-date is considered important in maintaining a complete and consistent design basis and overall configuration control. Consider adding more emphasis to the maintenance of System Descriptions.
0 Training related to the use of the Calculation Utility is not included in Engineering Personnel Job Familiarization Guide (JFG). It is understood that this training requirement is being added to the next revision of the JFG.
Findings for This Area There was one Finding uniquely associated with the Calculation assessment area:

Calculation Error CRs initiated during the 2007 assessment are described in detail in Section 1.5.3 1.5.2.3 System Engineering Area Effectiveness Rating The Independent Assessment Team rates the System Engineering area as Effective.
Source Information The Independent Assessment Team conducted interviews of selected Engineering and Site personnel and reviewed selected documents from the list of documents provided in advance by FENOC (See Sections 1.6.1 and 1.6.2).
The team reviewed recent and past Plant Health Reports, and interviewed system engineers responsible for the following plant systems:
Med Voltage AC Boric Acid Addition Doors and Hatches 480 V AC Freeze ProtectionlHeat Trace Plant Computer ICs NNI Radiation Monitoring, Process and Area Component Cooling Water Feedwater HPI-EC Turbine Generator Containment Spray In addition, the team reviewed recent and past Fleet Engineering Programs Health Reports, and interviewed Davis-Besse program owners responsible for the following engineering programs:
Boric Acid Corrosion Control Equipment Reliability Service Water System Reliability Preventive Maintenance.
Page 21
Plant Engineering supervisors and the Plant Engineering manager were interviewed, as were selected management personnel from the Plant organizations responsible for operations and maintenance.
Observations In 2007, as in past assessment periods, System Engineering was generally praised as effective and responsive to problems and support assistance needs of Operations and Maintenance. Both the technical expertise as well as the dedication of the system engineers to support of plant activities were remarked upon by interviewees, and the Team found the same.
System engineers interviewed regarding the status and health of their systems were knowledgeable and engaged in system health monitoring and reporting.
Maintenance Rule systems overall health was reported to be Green for the current quarter (2Q 2007), improved from overall health White at the time of the 2006 assessment. This was attributable to completion of significant system health improvement related work as well as a change in the calculation of individual and overall system health. The change in the overall calculation of system health was stimulated by information obtained through benchmarking and discussions with industry groups. This change took effect after the 1Q 2007 Plant Health Report was published, and the 2Q 2007 Plant Health Report incorporates the new rating calculation protocols.
At the time of the 2006 assessment, eight systems were designated as in red health condition. At the time of the 2007 assessment, two systems remained in the red system health designation status. A review of system health information and interviews with the system owners of the 2006 red systems were conducted.
A summary of the recent history red system health ranking is shown below:
Page 22
System health recovery plans for the two remaining red systems (Plant Computer and 480 VAC) were reviewed and discussed with the responsible system engineers.
The Plant Computer health recovery plan was out of date. Actions different than the ones described in the recovery plan were being implemented, and the plan was scheduled to be updated in October. The new intentions involve expedited procurement and installation of several key plant computer system elements instead of refurbishment of the older existing elements. The Team found no fault with the newer intended course of action, and concurs that the plan should be updated as soon as practicable to reflect the new course of action. In the meantime, additional management attention should be provided for the activities being carried on to substitute for the attention normally provided through the plan development and approval process.
The 480 VAC system recovery plan (Rev 3 8/9/07) was generally satisfactory, but there were two elements the Team felt require attention.
First, several Maintenance Work Orders for replacement of molded case circuit breakers were within about six weeks of scheduled execution, but at the T-6 point, engineering and procurement restraints still existed that threatened execution of the work. No specific steps were being taken to overcome the restraints and it was judged unlikely that the scheduled work would be accomplished. This seemed contrary to recent actions taken to ensure system health related work is periodically reviewed for restraints and action taken when restraints are identified.
Second, in the plan section Corrective Actions and Estimated or Actual Corntietion Dates, For the five breaker failure issues: Molded Case Circuit Breakers ECD 10/01/07 the action to be taken was unclear. The action item indicates that The MCCB PM Orders that replace the greater than 20 year old MCCBs will be validated to be properly prioritized in accordance with existing FENOC guidance as Orders accomplishing MR (a)(?) Action Plan corrective actions.
How and when this action would lead to actual breaker replacement could not be determined. The Team suggests that actual breaker replacement is the action needed and the action that would serve as the completion criterion, not validation of prioritization, which leaves the estimated completion date for the MCCB replacements indeterminate.
The health recovery plan issues discussed above contributed to Finding 3 ANA on system health.
Page 23
A single point vulnerability study is not included in the current Equipment Reliability Excellence Plan. SPV reviews in the past have identified the EHC and ICs as presenting reliability challenges, and there are long-term projects to replace these systems with single failure proof digital designs. Interviews with station personnel responsible for the Equipment Reliability program, the Preventive Maintenance program, and for conduct of the activities presented in the Equipment Reliability portion of the Engineering Excellence Plan indicated additional SPV study is not thought to be of significant importance at present.
Most stations are performing or have performed some form of SPV study to identify plant equipment issues that cannot be addressed by revising PM regimes, but rather will require some other forms of mitigation, such as adoption of challenge-limiting operating procedures and reduction of vulnerabilities through design changes The lack of a plan to conduct single point vulnerability studies contributed to Finding 3 ANA on system health.
The health recovery plans were generally found to be suitable vehicles for identifying and guiding the work necessary to improve system performance and health to higher levels. The plans now often address activities necessary to progress to excellent (green) system health, and now often address threats to improving or continuing good system performance.
Completion of work identified in system health recovery plans since the 2006 assessment was markedly greater than in the period prior to the 2005 assessment.
The measures taken to support preparation and execution of work to improve system health were observed to be widely utilized and responded to. In particular, the designation of work orders in SAP as system health related, and presentation of these designations in the work management process work week restraint reports was judged to be having a significant beneficial impact. All personnel reviewing upcoming work weeks for work scope and work status now can see immediately which work orders have been designated as system health related, and thus are better able to take actions to make those orders ready by removing restraints, and to better judge schedule change requests which might reschedule system health related orders. This information is not only available through the work week restraint reports, but also more generally available through the SAP data query and sorting tools so individuals across the site can better monitor and respond to readiness activities they are responsible for.
Although problems with the generation of the Plant Health Report observed during the last assessment appear to have been resolved to a significant extent, some plant health report areas continue to be populated with data the system engineers do not trust and do not rely on. The data presented in the Report Card section of each report are suspect. In several instances, data in the Report Card section was contradicted by the system engineer in the SEs discussion of the Page 24
Nuclear Safety, Material Condition and Operational Focus elements of overall system performance. For example, in the 2Q 2006 Plant Health Report, page 203, the system engineers discussion of Operational Focus scoring elements indicates 0 Open Operator Work Arounds when the corresponding Report Card data table on page 201 says 1. Similarly where the SEs discussion indicates 5 open TMs, the Report Card data table indicates 7. The data included in the Report Card section of the System Health Reports should be able to be relied on by the system engineers as they craft their discussions in the Analysis section of the report. Instead, they have to independently obtain the correct information by other means.
The Team sought the data in the report card section of the plant health report in the form of a spreadsheet or database, with the intention of determining the dominance of the various factors across the systems. Contact with the FENOC fleet responsible individual indicated the report card data are not captured in one location in the form of a database or spreadsheet and are thus unavailable for analysis.
The Plant Engineering section addressed the Equipment Reliability program area in interviews and follow-up discussions.
Notable progress has been made in this area since the last assessment.
Criticality classification and validation for all approximately 66,000 components has been completed (7241 components are critical, and 12,700 are non-critical for a total of about 20,000 critical and non-critical components overall. This is consistent with other plant classification outcomes).
Multiple phases of analysis of the critical and non-critical components are planned. Phase 1 analysis, currently underway, involves the development of 42 PM templates and the analysis of about 14,000 critical and non-critical components covered by these templates (about 70% of the total number of critical and non-critical components).
At the time of this assessment all 42 Phase 1 PM templates had been completed and released for use in analysis of components.
At the time of this assessment, analysis of components in the phase 1 set was complete for 2,881 critical and 3,961 non-critical components for a total of 6,482 components analyzed to date with the 42 phase 1 PM templates (out of the 14,000 components of phase 1, and out of the 20,000 total population of critical and non critical components to be analyzed through all phases). Analysis of all components addressed by thirty-four phase 1 templates has been completed (4,294 components). Analysis of the remaining phase 1 components is proceeding using the other eight phase 1 templates but is not complete. The number of components analyzed to date (6,482) includes those analyzed to these eight templates.
Page 25
The analysis to date has resulted over 2,150 PM revision requests. Relatively few of these have been fully implemented and fewer still have been executed.
Completion of this phase 1 of the PM Strategy will involve generation of additional PM revision requests beyond the 2,150 or so developed to date.
Completion of later phases of the PM Strategy program will involve development of additional PM templates and PM revision requests. These PM revision requests will have to be implemented (processed through the work planning and scheduling processes to the point where they are incorporated into work week and outage scopes and schedules and made fully ready to work) and executed (carried out in the field such that the revised PMs have been performed on all affected equipment). Both implementation and execution involve potentially significant use of resources. Many stations find that their implementation and execution forces are initially challenged with the work to be done flowing out of the PM basis analysis, and unable to conduct the implementation and execution work without considerable delay while they prioritize and organize the work and resource it to get it all done.
At this point, a rough extrapolation of the number of PM changes indicates a total projected number of PM revisions for phase 1 of about 4,600 revisions in all for phase 1 analysis yield, and about 6,600 PM revisions in all for analysis yield of all phases. It should be possible to estimate the average planner and scheduler labor input to process a PM revision request and then estimate the total and to go resource requirement for the implementation work. It should also be possible to estimate the average yield of the implementation of a PM revision request in terms of the craft and support labor required to execute the planned and scheduled work orders for PM revision requests. These estimates would give an indication of the implementation and execution resources that could be required to carry out the overall PM upgrade.
The FENOC fleet is developing performance indicators for monitoring the PM strategy work. Indicators that allow the implementation and execution forces to see in advance how much and what types of work they will have to perform will allow them to get ready to do the work before it all flows out of the analysis phase in engineering. The results of the analysis performed to date can be used to support the implementation work and execution work by determining the yield of work output produced on average thus far and extrapolating that yield foward to predictions of the total of implementation and execution work that will result when the analysis is complete.
Specific Issues for This Area The following observations are made with respect to this area. None of these observations rise to the level of a finding, but are provided for consideration in the plant's improvement efforts.
Page 26
The Plant Computer health improvement plan should be updated, and in the meantime, management attention work being carried out should be heightened.
The 480 VAC health improvement plan should be reviewed for work restraints that might not be removed in time to support implementation, and the criteria for advancement into the next health status level should be reviewed to ensure they are objective and quantified.
A single point vulnerability study should be considered.
Projection of the number and nature of PM revision requests and related implementation documents, as well as the number and nature of field tasks that are eventually likely to result should be made available for station personnel who will soon have to plan and carry out the implementation and execution work to use in preparing to do the work without undue delay.
Data anomalies in the Plant Health Report should be resolved.
Findings for This Area The following findings are applicable only to this one assessment area:
2 ANA ER Program - Forecast of PM strategy workload, SPV analysis; 3 ANA System health activities - Plant Computer, 480 V AC, Radiation Monitors Findings are described in detail in Section 1.5.4 Cross Cutting Findings Applicable to This Area None CRs issued during assessment of this area CR 07-26522 NORM-ER-3103-D Rev.3 Does Not Indicate Replacement Frequency CR 07-26779 COlA ENG 2007 - NNI Module Not Included for Calibration Under PM 4222 CRs initiated during the 2007 assessment are described in detail in Section 1.5.3 1.5.2.4 Use of the Corrective Action Process (CAP) by Engineering Area Effectiveness Rating Page 27
The Independent Assessment Team's overall rating for the Corrective Action area is Effective. Progress is continuing to be made on corrective action backlogs. Engineering's implementation of the CAP is very good to excellent.
Source Information The Independent Assessment Team members reviewed a number of applicable Condition Reports in their assessment of the areas of Modifications, Calculations, and System Engineering, In addition to the insights provided with respect to the areas under review, this also provided insight into Engineering's use of the Corrective Action Program. Additionally, a sample of Engineering root cause analyses, limited and full apparent cause analyses, and a sample of " A F Condition Reports closed since the last assessment were reviewed. The team also used reviews of Condition Reports and Cause Analysis related to Engineering performed in the 2007 COlA of the Corrective Action Program.
The team also reviewed the DBAR section related to Design Engineering Condition Report (CR) Backlog Reduction to determine progress being made with respect to Backlog Reduction of investigations and corrective action completionhesolution. Similar statistics were obtained for Plant Engineering from the available management reports The engineering assessment used the results of the 2007 Confirmatory Order Independent Assessment of the Corrective Action Program, completed early this year, where appropriate. The engineering assessment focused on CAP implementation and did not assess the CAP processes that are common to all station organizations that had previously been assessed.
Observations for This Area Efforts to reduce the Corrective Action backlogs in Engineering are progressing satisfactorily and workdown curve targets are being met. Plant Engineering and Technical Support Engineering are very near their end targets. Design Engineering has further to go, with some impact noted from moving up 15RF0, but continues to make good progress.
The team found that Engineering was promptly initiating Condition Reports when appropriate. One exception was noted in that a CR was not issued to document an error in DC Calculation C-EE-020.01-010, Revision 30. Plant staff identified this calculation error during preparation of Revision 30, Addendum A03. A Post-It-Note was issued to address correcting the calculation in the next revision. The team questioned whether a CR should have been initiated, and after this discussion the station issued CR 07-27754 to document this error. It was noted that this error was in the conservative direction, that is, once corrected would increase overall calculation margin. This failure to initiate a CR when appropriate is considered an isolated instance.
Page 28
Condition reports appeared to be appropriately classified as Significant or Adverse. Issues that are not considered Adverse to Quality are documented and tracked through SAP notifications. The type of actions included requiring root cause analyses (SR or AR), full apparent cause analyses (AA), limited apparent cause analyses (AL), and no causal analyses required (AF, investigation but no causal evaluation required) and closed to trending, AC, corrective action, if any, already complete). The items chosen for root cause, full apparent cause and limited apparent cause analyses appeared appropriate; Two root cause evaluations were reviewed:
CR 07-18074, HPI Train 1 Discharge Piping Air Intrusion Root cause analysis of this event determined that the root cause was multiple valve failures (five valves total) that allowed gas from the Core Flood Tanks nitrogen blanket to leak into the HPI discharge piping.
Contributing causes identified were (1) lack of a questioning attitude (assumed excess use of nitrogen was a packing leak that had previously occurred without sufficient investigation) and (2) procedure content (HPI discharge venting procedure implement to address operating experience was not adequate to detect the presence of gas in the HPI discharge line).
The identified causes were examined in detail and the team believes that the root cause analysis missed opportunities to identify additional or alternate causes. Although the fact finding and chronological history appear to have identified the pertinent supporting information, the cause determination(s) were not to a depth that contributed to long-term resolution of the issue and station improvement. The root cause (five leaking valves) was a restatement of the results of the Problem Solving Team and added no new information or insight. The question of why five valves in series would fail (e.9. maintenance, design, operation, foreign material, common mode failure) was not addressed.
Additionally, no corrective action was included to investigate the failure mode after valves were repaired or replaced, and determine the failure mechanism. The failure mode was suggested as seat wear, but there was no physical evidence to either support or refute this, nor was there information provided to support or rule out other possible failure modes.
Although lack of a questioning attitude was identified as a contributing cause, there appear to have been multiple instances of lack of a questioning attitude, including (1) the assumption that the excess nitrogen use was the recurrence of a known problem, (2)
Managements failure to question that assumption, (3) operator failures to question and quit reporting continuing abnormal nitrogen additions, Page 29
and failure to question the lack of excess nitrogen in the containment atmosphere during a containment entry.
A process issue not identified is related to unresolved issues/assumed but not proven causes. A basic management principle for dealing with these types issues is (1) determine what the worst case scenario is and rule it out, and (2) put in place a monitoring program to determine if the conditions remain as expected or departed from expectations.
Failure to monitor the condition and establish criteria, and failure to reassess the assumed cause were significant contributors, if not the root cause of this event. Since the station has an Operational Decision Making Issue (ODMI) procedure that invokes these processes, an opportunity to examine why the process was not implemented (e.g. it meet the threshold) and whether a lesson learned is that it should have been (e.g. adjust the threshold?). An opportunity to examine and improve a process was missed.
Finally, the contributing cause of procedure content appears to be related to the implementation of the Operating Experience (OE) program, specifically INPO SOER 97-1. There was no discussion of and examination of whether the procedure content met the intent of the OE item. If the intent of the OE was merely to remove any trapped gases, then the procedure met the intent. However, if the intent of the OE item is identify unwanted intrusion of aidgas, the OE item was inadequately implemented since it was difficult, if not impossible, to detect whether gas or water was coming out the vent. An opportunity to examine the OE process effectiveness was missed.
Despite the shortcomings existing in the causal analysis, many corrective actions were included that address causes identified above but not identified (or developed) in the report. The training material for engineers to address lack of a questioning attitudellessons learned from the event did identify the multiple opportunities, the lack of continuing monitoring and the failure to reexamine the assumed cause.
Additionally, an interim action to install a sixth valve in line with five leaking valves did potentially address a possible design issue with the existing valves by installing a ball valve rather another gate valve similar to those that failed.
Overall, the team assessed that this Root Cause Analysis missed several opportunities to identify causes in a depth consistent with station expectations, particularly in the area of examining process implementation and effectiveness (ODMI 8 OE).
CR 06-11269, EDG Vent Damper May Not Be Structurally Adequate for Design Tornado DP Page 30
The root cause of this event was determined to be that the original design specification for the HVAC dampers did not identify tornado dlp requirements and that tornado d/p requirements had been interpreted to apply only to the support structure (walls/doors) and dampers specifically designed for the purposes.
Extent of Condition reviews also identified similar issues with HVAC dampers for some other HVAC dampers in non-safety-related rooms.
Potential issues with failed HVAC and room overheating were examined for each incidence as part of an operability review. The Operability Determination identified compensatory measures to be taken in the event of a tornado to ensure operability of the HVAC system dampers.
The team assessed this Root Cause Analysis to be clear, concise, and well-written. The cause identified appears appropriate and corrective actions were developed that will contribute to both short and long term resolution of this issue.
One full apparent cause evaluation was reviewed:
CR 07-24820, Errors in LP Condenser Piping Repair Calculation (C-CSS-043.03-006)
The Casual Analysis was reviewed relating to calculation errors related to a repair patch for a safety-related system. The team was initially somewhat skeptical that two engineers could independently make the same math and methodology errors, without some breakdown of the independence of the design review. However, the casual analysis did an excellent job of explaining exactly what happened. Interviews with the independent reviewer confirmed to the team's satisfaction that this issue was solely a human performance issue as identified in the causal analysis, and not a weakness in the design review process.
Overall, the team judged this apparent cause analysis to be clear, concise and meeting station expectations.
One limited apparent cause evaluation was reviewed:
CR 06-06652, CST Anti-Vortex Procedure Direction This CR was related to failure to update Operations Procedure OP-06233 to change the required level the changeover of CST suction for the AFWPs to prevent loss of AFWP suction. This level was previously 3 feet based on AFWP net positive suction head requirements, but the CST vortex calculation identified that vortexing (leading to air entrainment) may occur starting at a level of 3.44 feet. This issue was Page 31
identified during the last Engineering COIA, and the causal analysis was performed after the last Engineering COIA.
The cause was determined to be procedure content (Cause Code 802) in that the content of the procedure was not properly coordinated with the changes in calculation C-ME-037.01-003 Rev 1 and calculation C-ICE-037.01-001 Rev 0. This cause is a restatement of the problem and does not address why the procedure change was not coordinated with the calculation change.
The process for identifying impacts of design (including calculation) changes on other organizations is the Design Interface Evaluation (DIE) review process. Although not identified or discussed in the casual analysis, a review of Calculation C-ME-037.01-003 Rev 1, indicates that the mandatory DIE reviews by Operations, Maintenance and Systems Engineering, were waived by the principal engineer and the waiver approved by the supervisor. This review process is intended to psrmit the reviewing organization to identify potential impacts of the proposed change. Failure to send the DIE to Operations, in this case, prevented operations from performing this review and presumably identifying the needed change. (It was also noted that a later Condition Report (CR. 06-11157), also found that the System Descriptions affected by this calculation was also not updated).
Overall, the team felt that the causal analysis was not performed in sufficient depth to identify a process issue (waiving a DIE review when an impact existed) not a procedure content issue was the identified cause of this problem. Though limited apparent cause analyses are not intended to be to the depth of analysis of a root or full apparent cause, the team feels that an opportunity to identify (and correct) a process issue with waiving DIE reviews was missed.
One " A F Investigation was reviewed:
CR 07-23106 documents that commitments to NUREG 0612 with respect to Heavy Loads had not been incorporated in the USAR. The investigation reviewed RIS 2005-25 Supplement 01 and concluded that it is required that all analyses of new safety issues performed by the licensee at the NRC's request, in this case, Davis Besse responses to NRC's request for information related to methodology for compliance with NUREG 0612 be included in the USAR. The corrective action specified was to update the FSAR to capture the analysis performed for RV Head Drop over fuel assemblies in the USAR. There were no investigation or corrective actions related to the determining the adequacy of the process of identifying needed USAR changes.
Although such investigation or corrective action is not required for a
" A F type CR, the team felt that a more in-depth investigation or an Page 32
update to require some form of a casual analysis may have been warranted in this case. It is recognized that the current USAR update process might be significantly different from the one in place at the time of the response to the request for information related to NUREG 0612. However, an opportunity was missed to examine the current USAR change process and determine whether additional guidance may be needed to capture USAR changes such as the one.
Specific Issues for This Area The team assessment was structured to avoid duplication with the recently completed Corrective Action COIA. The team focused on implementation of the program by Engineering. Process issues found in the Corrective Action COIA should be considered as equally applicable to Engineering.
There were no observations in this area.
Findings for This Area 4 ANA Analysis of process related weaknesses Findings are described in detail in Section 1.5.4 Cross Cutting Findings Applicable to This Area None CRs issued during assessment of this area None 1.5.2.5 Effectiveness of Assessment Process Area Effectiveness Rating Overall, the team rated the self-assessment process as Effective. This is based on the quality of self-assessments, interviews with engineers and managers, and the receptivity and responsiveness management exhibits toward the self-assessment process.
Source Information The Independent Assessment Team conducted interviews of selected Engineering and Site personnel and reviewed selected documents from the reference library (See Sections 1.6.1 and 1.6.2).

Of the three reports unavailable for review, one is the self-assessment for the Component Design Basis Review - it is nearly complete, and on track for completion in 2-3 weeks; the second was an assessment of Cyber Security which has restricted distribution; and the third of Reactor Head Movement Control is overdue.
A review of eight assessments, (six IPAs and two snapshot) was performed and the following noted:
e The Independent Performance Assessments appeared to be critical and resulted in identification of areas to improve. The corrective actions are tracked by condition reports or SAP notifications. (13 condition reports and five SAP notifications generated)
Page 34
The use of external assessment team members to gain outside perspective of engineering effectiveness was quite limited.
a This COlA is one of only two focused assessments scheduled for Davis-Besse engineering in 2007.
The implementation of some snapshot self-assessments needs attention (further explained in 5 ANA below):
> A snapshot self-assessment was performed in preparation for a NRC inspection for movement of heavy loads in early July 2007.
As of September 20, 2007, the self assessment has not been formally documented with a written report.
9 The AOV program tri-annual performance assessment was performed by participating on a snapshot assessment team at Beaver Valley. While the general aspects of the fleet AOV program procedure and practices could be evaluated there.
The team could not find any evidence from interviews and document review that the implementation aspects of the program at Davis-Besse were thoroughly assessed.
In May and June 2007, a collegial assessment of lNP0 05-005.Guidelines for Performance Improvement at Nuclear Power Stations was performed. Several performance gaps were identified, and among them was the need for a prioritized, long-range, living self-assessment plan. This COlA team has raised issues similar in nature for the past 3 years - see the following quote from the 2006 report: The assessment team was not able to determine the stations strategy for selecting assessment areas. The Fleet and station develop schedules for focused and snapshot self-assessments but there is no strategy guidance that we have found after inquiring for the past iwo COIA assessments. It was noted that in 2005 several focused self-assessments were related to engineering subjects.
but in 2006 there are none scheduled. This year, the team probed to find ownership for and definition of the strategy for engineering self assessments. At the final Friday debrief, the Director of Engineering stated the Engineering department would own the strategy in the future.
The Design Basis Assessment Report is produced quarterly and assesses the health of design engineering section design basis, engineering programs, calculations, drawings, design criteria manual, engineering quality, and engineering workload activities. This practice provides management with a thorough periodic review (self assessment) of key design basis health issues.
The team observed part of the meeting of the Company Nuclear Review Board configuration control and equipment reliability sub-committee. The sub-committee is staffed with knowledgeable personnel who asked probing Page 35
questions, mentored where appropriate, and helped prepare the engineering managers for the challenges of the future.
Integrated Performance Assessments are performed by each Engineering Section twice each year. This practice establishes a consistent process for trending human, organizational, and program performance by binning and analyzing condition reports and other assessment information. The aggregate information is presented to the management team and later rolled up to the fleet level. It should provide early warning of isolated issues that may be occurring but are spread across the fleet and hard to detect or correlate.
Three DB Fleet Oversight Quarterly Reports were reviewed for engineering issues and are listed above. These were Quarterly Quality Assessment reports for Q4-2006, (21-2007, and Q2-2007. The assessments covered the following engineering areas: Equipment performance trending, problem solving and decision making, and selected modifications. Condition reports were generated as necessary.
The receptivity, responsiveness, and aggressiveness of management and staff to resolving issues raised in self-assessments were evaluated by conducting interviews of engineers, oversight personnel, and managers. In addition, several condition reports and SAP notifications for 2005 and 2006 self assessment items were reviewed to evaluate aggressiveness to address issues. The sample revealed that 10 of 11 were complete and closed. Overall, the results of the interviews and CRhotification review of previous years self assessments indicated management was aggressively addressing the issues generated by the self-assessments.

CR 07-27389 COIA-ENG-2007 - AOV Program Self Assessment Implementation Not Evaluated CRs initiated during the 2007 assessment are described in detail in Section 1.5.3 1.5.2.6 Follow-up to ANAs from 2006 Area Effectiveness Rating The Independent Assessment Team rates DB Engineering Performance in this area as Effective. Opportunities for improvement were noted Source Information The team reviewed the actions taken on last assessment's Areas in Need of Attention (ANAs) including those documented on Condition Reports initiated following the last assessment.
There were no Areas For Improvement (AFls) from the 2006 COIA-ENG assessment, therefore no Condition Reports or Action Plans were required.
However, FENOC's DB CNRB recommended during the February 2006 meeting that DB use CRs to track action on the findings of the 2005 assessment, and this practice was continued in response to the 2006 assessment findings. The team considers this a good practice.
Seven CRs were initiated to track response to the 2006 findings. These CRs covered each of the ANAs from the 2006 assessment.
The team reviewed these seven CRs as well as additional related documents provided by FENOC for the assessment library (see Section 1.6.2). The team also interviewed individuals responsible for the Investigation Summary and for authorizing closure of the CR corrective actions for the Condition Reports issued to resolve the 2006 Findings.
The following seven CRs were initiated to address findings from the 2006 assessment:
CR07-12143 COIA-ENG-2006 Area In Need of Attention - Inattention to Detail In Calculations (ANA 1)
CR 07-12147 COIA-ENG-2006 Area In Need of Attention -

Twenty-two CAS were initiated from the seven CRs . All CAS had been closed before the 2007 assessment site visit began. The CAS were found to generally responsive to the problems identified in the CRs, which were in turn, generally responsive the findings of the 2006 assessment. The team noted that one 2006 finding did not result in any corrective actions (ANA 3). This is discussed below.
The CAS are discussed in relation to each of the respective Findings.
Review of response to 1 ANA Inattention to detail in calculations.
This finding was addressed by CR 06-12143, for DBDM, CR category AF, closed 5122107.
The CR problem statement captured the problem the team identified, and the CR investigation was thorough and included consideration of additional instances of similar problems. The investigation included review of the errors to identify human performance tools associated with each error.
Each individual error identified in the CR was resolved as indicated in the Origination section of the CR. Resolution of most individual items was complete, with a couple of items yet to complete but being tracked to completion.
Corrective action # I was to present the errors identified in the CR together with the applicable human performance tools to Design Engineering personnel on 4/26/07. The presentation material is available as an attachment to CR06-12143 in CREST.
Corrective Action #2 was to define the variables associated with volumetric flow rate and partial volume in Calculation 015.044 Rev 01 with a post-it-note (PIN) completed 4/6/07.
Review of response to 2 ANA Implementation of requirements from calculations Page 39
This finding was addressed by CR 07-12147 for DBDM, CR category AF, closed 9/21/07 although the CASfor this CR were all closed prior to that date.
The CR problem statement captured the problem the Team identified, and the CR investigation was thorough. The investigation covered each of the three examples provided by the Team.
There were seven corrective actions for this CR.
Corrective Action # I called for signs to be posted at each gate into the dry Fuel Storage Area that would prohibit flammable materials and combustible liquids from being stored on the pad. This action was closed on 3/24/07, However, despite this action and the procedural requirements against flammables and combustible liquids on the pad, some combustible liquids were subsequently discovered to have been placed in C-Vans stored on the pad. This resulted in a non-cited violation from the NRC. The team views this problem as not the direct responsibility of Engineering, but rather a more general shortcoming in the performance of the Plant I Site organization in imposing and adhering to procedure requirements and obeying signage, likely involving change management processes and techniques. The shortcomings of previous actions taken to exclude combustibles from the dry cask spent fuel storage pad in the context of change management processes were not addressed.
Corrective actions 2-7 involved presentation of issues and lessons learned from this CR in use of the DIE process and SAP notification to communicate requirements of calculations and analyses to users to ensure effective and timely implementation. The presentation material is attached to the CR in CREST.
The team notes that the more general issue of use of the DIE process to achieve knowledge of and control to engineering requirements for operation and maintenance of the plant is the subject of 2007 finding IANA Waivers of DIE Reviews.
Review of response to 3 ANA Equipment Reliability Program This finding was addressed by CR 07-12148 for Plant Engineering, CR category AF, closed 5/8/07 The CR description of the problem stated the following from the 2006 COlA assessment report "the equipment reliability program has taken too long to be implemented and is therefore not providing the benefits needed in protecting against equipment performance degradation and equipment failures" and it went on to add Page 40
Failures of equipment attributable to PM scope omissions or excessive intervals have been previously identified by other assessments (INPO, DE-SS-06-26 Common Cause Review A F l #2)
The Plant Engineering CR resulted in the conclusion Process should remain as is and No further action is required at this time and no corrective actions were generated to resolve this finding. The Team took this response to indicate Davis-Besse felt the Equipment Reliability Program contains the elements needed for success in this area, and that these elements would be implemented in due time in accordance with the ER section of the Engineering Excellence Plan and CAP items generated from other assessments.
The team reviewed DB-SS-06-26 Davis-Besse Common Cause Review July 2006 approved August 24, 2006, which was referenced in the response to CR 07-12148. This Snapshot Assessment was a review of site CRs with either root or apparent cause evaluations completed between 6/1/2005 and 6/30/2006. The assessment found seven common factors applicable to a majority of root or full apparent cause evaluations, including two factors not previously identified as trends, one of which was preventive maintenance deficiencies.
An AFI was written for the PM deficiency, which indicated PM deficiencies were a common factor in seven root or full apparent cause evaluations completed within the past year and in another two of the limited apparent cause evaluations....Plant Engineering organization to develop comprehensive actions to improve implementation of the PM process such that consequential events are mitigated (Pg 2).
CR06-03303 was initiated to address the problem stated by the AFI as PM deficiencies were a common factor in seven of the 69 root or full apparent cause evaluations and in another two of the 707 limited apparent cause evaluations completed within the last thirteen months.
Nine examples of preventive maintenance deficiencies addressed by root or full apparent cause evaluations were explicitly addressed in the problem statement and investigation summary for this CR. Each of the examples was itself the subject of a previously issued CR. Each of the seven CRs with a root or full apparent cause evaluation was determined to have led to corrective action including development of PM measures to prevent recurrence, and thus the PM deficiencies found in the cause analyses for the individual CRs were being remedied through specific PM revision requests. There were two CRs with limited apparent cause evaluations (CR06-01977 and CR06-01179). These CRs were found to have led to appropriate corrective actions (PM revision for CR06-01179, no PM revision for CR06-01977). Although CR06-03303 resulted in no additional corrective actions (beyond those initiated for the nine CR examples)
Page 41
the team concluded that this was an acceptable outcome, especially in light of the progress observed in the ER Program area described further below.
The CAS specified for the nine CRs used as examples in CR 06-03303 were reviewed in varying levels of depth to determine the effectiveness of their implementation through to revisions of PM tasks.
One CR resulted. CR 05-0988 addressed an instance of pressurizer spray valve RC2 unexpectedly opening for approximately 53 seconds on 12/28/05. The analysis concluded that PM revisions for several NNI modules in the Reactor Pressure Control system were warranted. Seven modules were named for institution pf periodic inspection and calibration, including module 3-8-9 (Memory
- SCR controller). PMA DB-REV-06-0048 was issued on 1/27/06 to bring about these PM tasks for all seven modules. This PMA was closed on 7/24/2006 when it was recognized that PMA DB-REV-05-1184 initiated 10/25/2005 addressed the same subject (almost).
The earlier PMA in fact only addressed six of the seven modules addressed by PMA DB-REV-06.0048, but did NOT include module 3-8-9 (in section 42 revision description). Thus PM for module 3-8-9 was dropped. CR 07-26779, initiated during the 2007 COIA, documents this omission.
The general response to CR 07-12148, the CR written to address the 2007 COIA finding, is believed by the Team to signal DB's view that since considerable initiative has been undertaken to address failures associated with individual equipment failures associated with PM deficiencies of sufficient significance to require at least a limited cause analysis, and since ER Program implementation progress in the past year has been significant, no additional corrective actions were required to address the ANA finding #3 of the 2006 assessment report.
The Team concurs with respect to the response to the CR The ER Program progress achieved since the 2006 assessment includes:
Completion of validation of classification of station equipment according to equipment criticality definitions based on INPO AP-913.
Generation of a number of PM Templates applicable to Davis-Besse (Phase 1)
Analysis of the PM regimes for many critical and non-critical components associated with the templates Generation of PM revision requests for a number of the completed analyses Transmittal of PM revision requests from engineering analysis workers to implementation workers for development of revised or new maintenance work orders and order execution schedules Beginning of execution of the new and revised work orders in the field Additional information about the Team's review and assessment of the ER program can be found in section 1.5.2.3 System Engineering Page 42
Review of response to 4 ANA Red plant health systems This finding was addressed by CR 07-12150 for DBPE, CR category AF, closed as of 7/2/07, The CR problem statement captured the problem the Team identified.
The investigation noted a number of actions that had been taken by the time the CR was written to improve overall system health, generally in the areas of 1) improved identification of system health deficiencies and threats to system health, 2) achieving authorization and priority for tasks needed, and 3) supporting decisions to make priority tasks ready for execution and to carry them through to completion. It went on to indicate ...the communication of work priority from the system expert to work management is the outstanding aspect that needs to be addressed.
There were two corrective actions.
The first corrective action addressed development of a process for system engineering to communicate to Work Management the priority of orders which would affect system health (health improvement items). This process involves designation of a system health color by the system engineer in SAP for work orders necessary to move a system from one health color level to another, and also to establish a schedule note indicating the order is associated with system health improvement.. This information is prominently presented in the restraint code reports generated by Work Management, which are held in hand by personnel reviewing work week scope and content and thus are reliably used as decision input. Conversations with system engineers and work week management personnel indicate they are highly aware of this information and understand the need to maintain work so designated in work week scopes. This information also supports outage work scope review and decisions about outage scope made using the scope control and schedule change request processes.
The second corrective action called for addition of anticipatory factors such as parts unavailability, obsolescence, age related degradation and assessment of impact of deferred work to the System Health reports. NOBP-ER-3009 Rev 2 (dated 6/25/07) accomplished the addition of obsolescence information. The 2Q 2007 Plant Health Report shows inclusion of information of these types.
These changes have and will continue to support more reliable and timely execution of work items supporting system health improvement.
In addition, as discussed in section 1.5.2.3, significant progress has been made since the last assessment in executing maintenance work orders and plant modifications to resolve longstanding equipment reliability and condition issues, and further, significant additional work order and modification executions are Page 43
scheduled during the remainder of the current operating cycle and during 15RFO. Reviews indicate a high level of readiness of these work items, providing confidence that the problem resolutions and plant health improvements they represent will occur as planned and scheduled.
Review of response to 5 ANA ECP Revision Reviews This finding was addressed by CR 06-6388 for DBDM, CR category AF, closed 5/25/07, The CR problem statement captured the problem the Team identified The investigation for this CR concluded that the problems identified were attributable to knowledge deficiencies on the part of some engineering staff (not deficiencies in the intent or delineation of instructions).
There were two corrective actions.
The first called for a presentation to be made to the Design and Rapid response Engineering staff to address the procedural requirements and expectations. This was completed in December 2006.
The second corrective action called for Fleet review of the issues to evaluate the need for procedure changes. This action is complete, with no changes found to be required.
Review of response to 6 ANA Follow-ups to assessments and last year's COIA-ENG-2005 This finding was addressed by CR07-12151 for DBTS, CR category AF, closed 7/2/07.
This ANA addressed the effectiveness of the DB response to the findings of the 2005 assessment. In 2006, the Team reviewed the resolution of the 2005 findings and found that some findings or elements of findings were not being captured and/or acting on, resulting in forgone opportunities for performance improvement.
CR07-12151 captured the problem in the description of condition by quoting from the Team's 2006 report, so the problem statement reflected the issue presented by the Team in 2006.
The investigation section of the CR for the 2006 finding of shortcomings in the responses to the 2005 findings essentially quoted more extensively from the Team's 2006 report. The investigation did not address the matter of why or in what way the responses to the 2005 findings came to have shortcomings that could lead to forgone opportunities for performance improvement. It instead Page 44
addressed five specific examples of problems from the 2005 report identified in the 2006 report as having not been satisfactorily resolved.
There were five corrective actions for this CR.
CAS 1,2, and 3 relate back to the copper dust in containment issue of 2005. In the 2005 and 2006 reports the Team suggested some principles of problem management in general by using examples from the copper dust issue (For one, describing the intended achievable ultimate end state to aid in determining if the problem has been taken to its achievable end, and for another using decision tree type tools to anticipate potential contingencies and predetermining decisions to be made, decision criteria, and information that would be needed to support decisions). DB has responded only to the examples, not the more general matters. The Team will not be pursuing these matters further at this time.
CA 4 makes note of a measure previously articulated by DB concerning an enhancement of the DIE process to much more effectively communicate the results of engineering evaluations to Operations, Maintenance, and others when the Engineering evaluations result in requirements for control of the plant configuration that must be executed by the plant. The CAS description directs that a (SAP) Notification be created to:
"Add to section 4.2.1.2 of NOP-CC-2004, Design Interface Reviews and Evaluations, the intent of the following statement:
Design inputdassumptions under control of Operations or other organizations should be flagged in the body of the engineering document, restated in the resultdconclusions of the document and discussed on the DIE cover page. Additionally, the notifications or condition reports generated to track procedure changes as a result of the DIE review should be reviewed and/or augmented by Engineering to provide assurance that the applicable engineering requirements are propagated effectively. "
Notification 600366019 was created in response and assigned to Fleet. The revision is planned for inclusion in the procedure revision expected by the end of 2007.
The Team anticipates completion of action on this item such that it becomes effective at the DB site.
CA number 5 was not implemented as written because data identifying the specific instances of SAP notifications addressing self-assessments found in 2005 to have been inadequately resolved could not be recovered. However, the DB individual assigned to the CA acted commendably in trying to determine if he could find additional instances of the problem the Team identified. He reviewed a number of self-assessments and traced the findings into SAP, finding that all seemed to be progressing to resolution properly. The Team, in 2007, requested Page 45
a search for any SAP notifications that were opened and closed on the same day without justification, as potential additional examples of a problem using SAP that caused items to be closed prematurely and without having been accomplished.
Three were found, but based on preliminary information on those three, it seems unlikely that this remains a problem.
With all the above taken into account, the Team found the results of use of the CAP by Engineering to capture and resolve the findings of the 2006 findings was much improved. This is attributed to DB's engineering management awareness of the problem and their actions taken to ensure that the CRs for the 2006 findings would be improved in quality and effectiveness.
Review of response to 7 ANA Management of engineering workload This finding was addressed by CR 07-12153 for DBTS, CR category AF, closed 6/27/07.
CR07-12153 captured the problem identified in the finding.
There were four corrective actions for this CR.
The first three CAS called for work management tools to be selected, development of an implementation plan, and application of the software and plan as a pilot project in the Rapid Response organization. These actions were substantially completed. CA #M was a place-holder with no unique action to be taken.
The engineering work management process is, as the response to the CR indicates, a work in progress. The Team found that many engineering personnel, from individual engineers to managers, were utilizing the SAP and P5 tools to varying degrees in managing their individual and group workloads. Progress has been made, benefit is beginning to be realized, and management will need to extend the plan and it's deployment to improve the results.
Review of responses to CRs generated during the 2006 Assessment There were two CRs generated during the 2006 assessment CR 06-6388 Inconsistent practice in reviews and design verification for ECP revisions.
This CR was written during the 2006 assessment, is the response to 5ANA, and is discussed above.

There is a discussion of the cause determined by the limited apparent cause analysis performed for this CR in section 1.5.2.4 above in the results of the assessment of area 4, Use of the CAP by Engineering. In that section it is cited as an example in support of 4 ANA Analysis of process related weaknesses In brief, this CR was found to address the specific instances cited, but to be substantially lacking in effectiveness to investigate and resolve the significant underlying process problems the specific examples represented.
Findings for This Area There were no Findings uniquely associated with this assessment area Cross Cutting Findings Applicable to This Area None CRs issued during assessment of this area None 1.5.3 CR summary This section summarizes CRs written during the assessment related to assessment reviews, discussions, and findings Five CRs were written during the Independent Assessment.
CR 07-26522 NORM-ER-3103-D Rev.3 Does Not Indicate Replacement Frequency The PM template for breakers does not contain a replacement task and frequency for molded case circuit breakers. The June 24, 2004 Technical Bulletin TB-04-03 indicates the life of Westinghouse supplied molded case circuit breakers for mild environment applications is 20 years.
CR 07-26574 COIA-ENG-2007 - C-EE-02.01-010-Rev 30 (DC Calc) Addendum A03, Calculation Error Plant staff noted an error in the application of calculation assumption 2.5 related to the percentage of solenoid loads to be considered in relay panels. The assumption specified the use of 67% of the solenoid loads while the calculation had actually used 100%. This error did not adversely affect the conclusions and a Post-It-Note initiated to correct the error in the next revision. Discussion with plant staff determined that a Condition Report should have been initiated to document this error. Correction of Page 47

2007 Findings Areas of assessment 1 ANA Waivers of DIE Reviews X 2 ANA ER Program - Forecast of PM strategy workload, SPV analysis X 3 ANA System Health Activities - Plant Computer, 480 V AC, Radiation Monitors X 4 ANA Analvsis of Process Related Weaknesses X 5 ANA Assessment strategy and implementation I 1x1 Discussion of findings None of the five ANAs were applicable to more than one assessment area. By comparison, three of the seven 2006 ANAs were applicable to more than one assessment area, and five of the six ANA findings in the 2005 assessment were applicable to more than one assessment area. Thus the 2007 findings were somewhat narrower in applicability.
Three of the 2007 findings are related to findings of the 2006 COIA-ENG assessment. These relationships are not considered strong enough to be considered repeat findings. Rather, they are thought to be similar in some respects, but in all cases lesser in scope and significance, than the related findings from 2006.
The 2007 finding 1 ANA Waivers of DIE Reviews is related to the 2006 finding 2 ANA Implementation Of Requirements From Calculations in that the instances cited in this year's findings have involved information not being translated into engineering and plant documents through the DIE process, although for different reasons.
The 2007 finding 2 ANA ER Program - Forecast of PM strategy workload, SPV analysis is related to the 2006 finding 3 ANA Equipment Reliability Program, although the 2007 finding addresses issues of reduced significance and scope.
Page 50
The 2007 finding 3 ANA System Health Activities - Plant Computer, 480 V AC, Radiation Monitors is related to the 2006 finding 4 ANA Red Plant Health Systems, although the issues are smaller in number and scope.
Findings statements The following section contains the findings statements and their bases.
1 ANA Waiver of DIE Reviews The waivers of mandatory Design Interface Evaluation (DIE) reviews by the principal engineer have resulted in several instances where impacts of calculation alterations on plant procedures or documentation have not been identified and updated in a timely manner.
Waiving of mandatory DIES is allowed with supervisory approval and this approval was obtained in each of the instances noted.
The justification for waiving mandatory DIE reviews was that the necessary changes to plant procedures and documentation are identified in a parallel process or review, e.g. as a result of CRs that initiated the calculation alteration or as part of the DIE review of an ECP package. The team found that that the assumption that the other process or review would identify the impacts of calculation alterations is not necessarily valid (see examples below).
The principal engineer and the design organization may not always be in a position to determine all the impacts a calculation change may have. A verification that the output documents assigned a DIN number in the calculation Design Index Numbers (DINS) are not affected is not sufficient to identify whether any additional documents may be affected. It is noted that many System Descriptions are not listed as output documents, although the calculation is listed as a System Description reference.
Specific examples include:
Mandatory DIE review by Systems was waived for calculation C-ME-011.01-141. The System Description value (SD-18, Table 2.1-4) for pump submergence requirement is 4.33 ft, while the calculation result is 4.14 feet. Additionally, this calculation is SD reference 4.1.117 to the SD; reference 4.1.117 needs to be added to the list of data sources on the table.
Mandatory DIE review by Systems was waived for calculation C-NSA-049.01-004 Rev 1. The calculation analyzed the acceptability of tank low-level setpoints to prevent vortexing. Follow up with the principal engineer identified that there were System Description impacts from the calculation change. This calculation is not referenced in the SD. Notification 600352155, dated 12/6/06, identified the need to update several System Page 51
Descriptions to include anti-vortexing requirements and reference appropriate calculations. In this case, a DIE review form sent to PE would have served to alert the preparer of the System Description changes to any additional changes resulting from Rev 1 (issued May 2007).

ER Program Forecast of PM strategy workload, SPV analysis Single Point Vulnerability analysis; and forecast of PM strategy workload on PM implementation and execution areas are not planned or evident Industry practice in the equipment reliability area generally involves conducting single point vulnerability analysis to inform plans to improve reliability where PM changes are not practicable. Davis-Besse does not have comprehensive SPV results or plans to conduct SPV analysis, according to the FENOC Engineering Excellence Plan and interviews with Davis-Besse station personnel.
The PM Strategy work underway at DB at present is recognized to be somewhat behind many in the industry. Engineering analysis of critical and non-critical components is about 30% complete. The results of that analysis and the thousands of PM revision requests it will generate, and the thousands of work order and schedule changes and field task executions that will be required to give full effect to station equipment will be a formidable burden for the stations work management and field forces. Those organizational elements need planning information to organize the resources that will be needed to carry ut the work without undue delay. Davis-Besse Engineering currently are not forecasting the workloads that will impact the organizations downstream of the engineering analysis in the ER process.

System health activities Plant Computer, 480 V AC, Radiation Monitors Supplemental management attention for system health activities and plans are needed for Plant Computer, 480 V AC, and Radiation Monitors process and area.
These plans involve the need to be revised to reflect actual plans and intentions, to remove ambiguities, and the need to consider contingencies and uncertainties such as continuing availability of parts and services, system expertise, and uncertainties in approval of future phases of replacement and/or upgrade.
The PC plan has been overtaken by events, and is not being followed to a significant degree.
The 48OVAC plan contains ambiguities and calls for actions that could only be scored complete through highly subjective judgments. And some near-term scheduled activities were found to be restrained with no plan to relieve the restraints.
Page 52
The Radiation Monitoring System health is subject to threats and uncertainties in several dimensions, such as continuing availability of parts, availability of current service providers, maintenance of internal system expertise, and future authorizations for the next phases of subsystem upgrades and replacements.
4 ANA Identification of Process Weakness in Causal Analyses and Investigations I Some casual analysis and investigations have not been performed in sufficient I I depth to identify process weaknesses.
Examples include:
CR 07-18074, HPI Train 1 Discharge Air Intrusion, Root Cause Analysis, did not identify issues related to Operational Decision Making process as a root or contributing cause and did not investigate potential weaknesses in the Operating Experience program implementation. Additionally, the root cause was identified as five in-series valve failures. This root cause did not go further in depth to determine the cause of the valve failures (design, maintenance, etc.). Seat wear was identified as the failure mode, but there was no evidence provided to support this hypothesis or to discount other plausible failure modes. No corrective action was put in place to further evaluate the failure mode when the failed valves were repaired/replaced.
CR 06-6652, CST Vortex Procedure Deficiency, Limited Apparent Cause identified procedure content as the cause, but did not investigate or identify why the DIE process was not effective, or in this case, not used.
CR 06-11157, CST Usable Volume not Updated in System Description, C F Investigation, determined to the CREST Cause Code to be Work Practices/ Workmanship in that Plant Engineering staff failed to identify the needed System Description update as part of the DIE process. The investigation did not identify the Systems mandatory DIE review was waived by the principal engineer. The process issue related to the waiver of the DIE was not investigated or addressed.
CR 07-23106, USAR Description for Control of Heavy Loads, A F Investigation, determined that the USAR description of the control of heavy loads was minimal and did not contain information supplied in a response to an NRC request for information with respect to methods for implementation of NUREG 0612, as required. The corrective action was to update the USAR with respect to this area. The investigation did not examine the processes used to identify needed USAR changes nor the engineering-regulatory compliance interface with respect to this process.
The CREST Cause Code assigned was BOI, Document content. The team felt that an opportunity was missed to examine the current process for identifying needed USAR changes with respect to how that process Page 53
currently handles responses to NRC requests for information and how that process is implemented in engineering. It is recognized that this process may be a regulatory compliance process rather than an engineering process.
Failure to identify or consider related process issues in casual analyses and investigations may result in failing to self-identify and address needed process improvements, either directly through corrective actions or indirectly through identification of adverse trends through the trending of CREST Cause Codes.
This issue is similar, in some respects, to the comment in the 2006 Engineering COIA, Corrective Action area, related to the treatment of some process and program issues as C F and not requiring causal analysis or consideration of process-related issues, and solely addressing the specific deficiencies identified.
The 2006 COIA comment was not deemed to rise to the level of a finding due to the relatively few instances identified.
5 ANA Assessment Strategy and Implementation Engineering management needs improve implementation of selected snapshot self assessments and also develop a long-range strategy for assessment of various Engineering processes and programs.
Two of three snapshot self assessments reviewed were in need of improvement in implementation and timeliness.
The self assessment of the AOV program took credit for tri-annual review of DB AOV process and implementation by going to Beaver Valley and participating in their snapshot assessment. The assessment team member then wrote a report about a couple of fleet programmatic issues, but didnt assess AOV program implementation at DB.
The pre-inspection snapshot self assessment for RPV head movement control, conducted in July, is still not formally documented with a written report.
Consideration should be given to establishing a long-range strategy for Engineering assessments; that is, determining the areas of focus for the future; choosing whether the assessments should be focused on compliance with current procedures and practices or the performance gaps using standards of industry excellence as a benchmark. A plan that includes a mix of IPAs, pre-inspection self assessments, snapshot and focused self assessments on selected topics to be assessed should be developed in accordance with the long-range strategy. The strategy and plan should be periodically reviewed and adjusted as necessary. This review and adjustment could be done as part of the IPA process.
