J. Grobe C. Lipa B. Ruland S. Thomas M. Phillips A. Mendiola J. Stang Z. Falevits Agenda Items:

1. Discuss/Approve Revisions to Inspection Plan for the Corrective Action Team Inspection The Panel discussed the proposed revision to the previously-approved corrective action team inspection plan. The Panel made some suggestions for additional improvement to the proposed plan, and requested that the changes be made next week and brought back to the Chairman for approval. The final version of the approved plan will be attached to these minutes. The Panel noted that it would need confidence prior to restart that the corrective action program for the licensee was effective in preventing cyclical performance.
2. Discuss Schedule for Meeting With Licensee to Discuss Safety Culture and Licensees Long-Term Plans The Panel reviewed various staff availability and concluded that a meeting in August was not feasible. The Panel recommended trying to schedule the meeting in mid-September.
3. Discuss/Update Milestones and Commitments The Panel reviewed and discussed upcoming milestones and commitments.

REVISED INSPECTION PLAN (Cover Letter) Rev. 8-21-03 CORRECTIVE ACTION IMPLEMENTATION TEAM INSPECTION Davis-Besse Nuclear Power Station Inspection Report Number 50-346/2003010(DRS)

(Do not share this Inspection Plan with the licensee)

Inspection Objectives The 0350 Oversight Panel established for Davis Besse determined that a comprehensive review by the NRC was needed to assess the implementation of the licensees upgraded corrective action program. This is required to determine the effectiveness of the corrective action process in identifying, correctly assessing, and promptly correcting risk-significant findings.

In addition, this inspection will fulfill the baseline inspection program requirements for the biennial portion of inspection procedure 71152 (Identification and Resolution of Problems). The biennial inspection objectives are to provide an assessment of the effectiveness of licensee problem identification and resolution (PI&R) programs, including problem identification, evaluation, and resolution, based upon a performance-based review of specific issues; to look for instances where the licensee may have missed identifying potential "generic" concerns, including specific problems involving safety equipment, procedure development, or design control. In addition, the team will also use applicable inspection guidance delineated in IP 93812 (Special Inspection).

Inspection Dates: March 17-21, March 31 to April 4, May18-23, August 11-15 and 25-29, 2003 EXIT: Thursday, September 9, 2003, at 1:30 p.m.

III Lead Inspector Preparation Activities Information Requests As part of the inspection preparation, the team leader listed selected corrective action documents in tables below. The team will select the documents to be reviewed. In addition, the team leader will request the required information from the licensee and will ensure that the necessary information be conveyed to the inspection team.

If during the in office preparation weeks, additional information is determined to be necessary, please inform the team leader.

5

IV Team Preparation Activities Review of Material Each team member will review the licensee administrative procedures that control the identification, evaluation, and resolution of problems. These documents will be reviewed to provide sufficient knowledge of the licensees revised corrective action program and process, as necessary to conduct an effective and efficient inspection.

Each team member will review documentation on licensee efforts to identify, resolve and prevent structure, system, and component performance problems through performance monitoring, root cause analysis, cause determination, and corrective action to meet the monitoring requirements of the maintenance rule (10 CFR 50.65).

Preparation Meetings A team meeting will be held on Monday, March 10, 2003, at 1:00pm. In this team meeting, the team leader will discuss the inspection plan and distribute available information provided by the licensee and specific inspector items for review and follow-up. Additionally, during this meeting, the team leader will go over inspection logistics and answer team questions.

Over the next several days, each inspector, including the team leader shall review the provided documentation and select additional corrective action items to be reviewed. Also, each inspector will become familiar with the requirements of the applicable NRC IPs.

Requests for Additional Information As soon as possible, but no later than noon on March 12, 2003, team members should provide to the team leader a list of any additional information and/or documents they want to have readily available on the first day of the inspection. The team leader will coordinate with the team members to ensure there is no duplication of efforts.

Selection of Specific Items for Review The samples chosen for review should include a range of issues including:

1. Licensee identified issues mostly documented in Condition Reports/Corrective Action Items (including issues identified during audits or self assessments);
2. NRC identified issues;
3. Issues identified through NRC generic communications;
4. Issues identified through industry operating experience exchange mechanisms (including Part 21 reports, NSSS vendor reports, EPRI reports, experience reports from similar facilities, LERs);

6

5. Specific or cross cutting issues identified by safety review committees or other management oversight mechanisms;
6. Issues identified through employee concerns programs V. Inspection Objectives The main objectives of the Corrective Action Team Inspection (CATI) are:

( To determine if the corrective action process at Davis Besse is being effectively implemented to identify risk-significant conditions at an appropriate threshold.

( To determine if the identified problems are being correctly prioritized for resolution and if the prioritization and schedule established by the licensee for implementing and completing the corrective actions is adequate and timely..

( To determine if licensees identified problems in important to safety systems are being evaluated using a systematic method(s) to identify the correct root cause(s) and contributing cause(s).

( To evaluate licensee's implementation of the corrective action program to address identified issues including determination of root cause(s), apparent cause(s),

potential common cause(s), and extent of condition evaluation.

( To determine if the corrective action process at Davis Besse is being effectively implemented and if appropriate corrective action is taken to prevent recurrence of identified problems.

( To review a sample of Restart corrective action items to determine if the corrective action items required to be accomplished prior to plant restart have been correctly characterized and actions had been completed in accordance with licensee and regulatory requirements.

( To review a sample of Post Restart corrective action items to determine if they were properly classified to be addressed after restart.

( To evaluate the licensee's effectiveness in assessing and correcting the risk-significant issues identified during the System Health Assurance/Readiness (SHRR, LIR and SFVP) Reviews

( To accomplish applicable inspection activities required by Inspection Procedures 71152 and 93812.

( To identify any adverse trends or patterns in implementation of the corrective action process.

7

( To assess effectiveness and determine how the licensee measures effectiveness of implementation of the corrective action program. Also, to review audits and self-assessments completed and planned to assess Corrective Action implementation.

( To review the assigned items (CRs, URIs, NCVs, LERs etc..,) and focus on adequacy of licensees assessment to identify the correct root/apparent cause(s) and the effectiveness of the corrective action process in addressing these causes, including extent of condition.

( To verify whether the licensee is reporting, in a timely manner, conditions that warrant 50.73 LERs or are they in violation of 50.73?

( Assess for repeat issues (CRs) or identified problems that need rework. Are these issues being trended ?

General Guidance for Review of Condition Reports Review each condition report against the following performance attributes:

( Did the licensee completely and accurately identify the problem in a timely manner, commensurate with its significance and ease of discovery?

( Did the licensee properly evaluate and resolve any operability or reportability issues?

( Did the licensee consider the extent of condition, the generic implications, whether there might be a common cause, or if there have been previous occurrences?

( Assess the validity of the licensees conclusions regarding extent of condition, consideration should be given to whether multiple risk significant design or performance issues have been identified.

( Is the licensee implementing an effective trending program to identify potentially significant adverse trends associated with human or equipment performance?

( Did the licensee classify and prioritize the resolution of the problem, commensurate with its safety significance?

( For any significant conditions adverse to quality, did the licensee identify the root and contributing causes of the problem?

( Did the licensee identify appropriately focused corrective actions to correct the problem? For significant conditions adverse to quality, do the corrective actions address the root and contributing causes.?

( Did the licensee complete the corrective actions in a timely manner, commensurate with the safety significance of the issue? Were extensions of corrective action due 8

dates adequately justified? Was combining of several condition reports under one new condition report justified ?

( If permanent corrective actions require significant time to implement, then verify that interim corrective actions or compensatory actions have been identified and implemented to minimize the problem or mitigate its effects, until the permanent action could be implemented;

( In addition, for samples that involve maintenance rule issues, the inspector should verify the following:

(a) The licensee has designated items under 10 CFR 50.65(a)(1) as appropriate, (b) Determine if corrective actions for 10 CFR 50.65(a)(1) items are adequate, (c) Review maintenance rule repetitive maintenance preventable functional failures (MPFFs) for indications of weaknesses in the licensees corrective action program. In addition, identify any problems with root cause analysis or cause determination and corrective action for items experiencing repetitive MPFFs or exceeding their goals or performance criteria, (d) Ensure that risk assessment, risk management, and emergent work control problems associated with maintenance are identified and resolved promptly.

Team Assignments Successful completion of the CATIs inspection objectives and procedure requirements requires good planning and team work. Therefore, the team is being divided into areas with the following general assignments:

Electrical Engineering/Design/Management/Assessments -Zelig Falevits Electrical Engineering/Design/Operations -Marty Farber Mechanical Engineering/Design/Operations -Patricia Lougheed Electrical Engineering/Design/Operations -Robert Daley Mechanical Engineering/Design/Operations -Al Walker Mechanical Engineering/Design -W. Bennett, Corrective Action, Consultant Mechanical Engineering/Design -J. Panchison, Mechanical, Consultant Electrical Engineering/Design -O. Mazzoni, Electrical, Consultant Mechanical Engineering/Design -W. Sherbin, Mechanical, Consultant Electrical Engineering/Design -F. Baxter, Electrical, Consultant Within these areas, the intent is to ensure that all inspection attributes are met without duplication of effort. To ensure effective teamwork and knowledge sharing, a daily afternoon team meeting will be held at 3:30 p.m. which will focus on how assigned activities are being completed and what remains to be done to accomplish the inspection objectives.

10

In addition, a meeting with the licensee will be held at 4:30 PM to inform the licensee of new issues identified and of information requested but not yet received. This meeting is to last not more than 30 minutes.

Assessment of Corrective Action Program At the completion of the inspection, the team will develop a clear and concise discussion of the results of their review. An assessment of the licensees corrective action program/process, based on the inspection results must be developed during the inspection.

By reviewing a sufficient number and breadth of samples, the team should be able to develop insights into the effectiveness of the licensees corrective action process. Compare the results of the teams findings with the results of the licensees findings, audits and assessments of the corrective action process.

IV Issues and Findings The Risk Informed Inspection Notebook and the Significance Determination Process (SDP) for Davis-Besse Nuclear Power Station have been developed and approved. Inspectors shall address the questions of Manual Chapter 0612 and process the finding through phase 2 of the SDP as necessary. Green findings will be documented in the inspection report.

Findings that appear to be "other than green" shall be immediately discussed with the team leader, the licensee and the senior reactor analyst, to ensure that Davis Besse PRA information is correctly considered. Enforcement action for green or non-SDP issues will be handled in accordance with the Enforcement Policy.

Unless an issue can be shown to be greater than minor, additional inspection time (over approx. 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />) should not be spent. If an issue appears greater than minor, then sufficient questions need to be asked of the licensee to enable the inspectors to confirm any assumptions and complete the Phase 1 and 2 worksheets. If a color cannot be determined by the end of the inspection, the issue will be described as an "unresolved item," pending final determination of the appropriate risk significance. Some flexibility will be allowed for documenting non-green observations due to the nature of the inspection.

V Documentation Inspection findings normally result in a number of questions being raised. These questions are to be given to the licensee verbally or, if written, the licensee must copy the information and the inspector must retain the written document. As part of the daily interfaces with the licensee, the team leader will go over the status of outstanding questions. Therefore, the team members need to keep the team leader informed of any concerns with timeliness or quality of responses to questions. Lack of response to questions will not be accepted as a reason for any delay in providing an input unless the team leader has been informed prior to the exit and the issue is one that will necessitate a writeup in the report. Any document requests generated on the day of the exit or afterwards must be approved by the team leader, must pertain to areas already inspected, and must be only for the purpose of ensuring an accurate document list entry.

11

Issues which the inspector deems meet the criteria for report writeups shall be discussed with the team lead prior to preparing an input. Inputs are to be e-mailed to the team lead within five working days (seven calendar days) of the exit. All documents critically/deliberately reviewed shall be included in the document list. Corrective action documents generated as a result of the inspector's questions shall be listed separately from corrective action documents that were in the licensee's system prior to the inspection.

VI Interface and Coordination Meetings Meetings with the Licensee On Friday, August 29, 2003, at 8:00 a.m. an extensive debrief will be held between NRCl team members and licensees staff to discuss all identified issues during this inspection.

All team members are expected to attend this debrief Routine Interactions Through-out the inspection, inspectors are expected to have routine interactions with licensee employees. It is expected that these interactions will be professional in nature and will normally be conducted without the lead inspector present. Any questions or requests for further information arising from these meetings will be conveyed to the lead inspector.

Exit Meeting The team leader will conduct the exit meeting on September 4, 2003 at 1:30 PM. Team members are expected to provide the team leader a final short summary of findings by Friday August 29. Team members do not need to attend the final exit meeting.

VII Starfire Information This special inspection is estimated to require approximately 960 (+/- 80) hours of direct inspection effort. The review will include mostly Restart as well as a small sample of Post-Restart corrective action items. Approximately 75% (or 700) of these hours should be spent as direct inspection evaluating effectiveness of the licensees corrective action program in assessment and resolution of identified risk significant issues and review of RAM items for closure (charge to IP 93812 with IPE code of ER). Approximately 25% (or 250) of these hours should be spent in reviewing CRs, LERs, URIs, NCVs, audits, self-assessments and other corrective action related issues to determine effectiveness of licensee corrective actions taken and proposed to resolve the identified issues and determine if they are ready for closure (charge to IP 71152 with IPE code of BI,). We need to fulfill the requirements pertaining to assessment of effectiveness of corrective action process delineated in IP 71152. Preparation and documentation for this inspection will use IPEs, SEP, SED, BIP or BID. The direct inspection hours do not include time spent in travel, entrance or exit meetings, debriefing the residents, checking on e-mail, or keeping track of hours to correctly credit them. However, it does include time spent in team meetings and in preparing for team meetings.

12

General Information Checking E-mail and Other Such Activities For planning purposes, the lead inspector has assumed that each inspector will spend a maximum of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> each week of the inspection, maximum of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, checking e-mail or doing other activities not directly related to the inspection. This time, if used, should be charged to general administration.

Travel Charges All travel time is to be charged in HRMS to an IPE code of "AT", including travel during non-regular hours (see below). For planning purposes, a total of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> travel is allotted for travel one way to the site.

Master Table and Status of Corrective Action Items from CATI Inspection Plan (Rev. 8-88-03)

Open: Reviewed selected/assigned Restart corrective action(CA) item(s) listed in the CR. One or more CA item(s) reviewed remains open due to additional actions needed by the licensee prior to closure. Will be reviewed by team when action completed and item(s) closed.

Closed: Completed review of the selected Restart or (Post Restart) CA item(s).

Licensees actions to address all Restart issues were found to be appropriate. No concerns were noted by the team. The Items reviewed can be closed in the report.

If concerns were identified by the team, document the concern and leave the item open until licensee addresses the concern.

Not Reviewed: Licensee actions to address these Corrective Action Item(s) has not been completed yet. Will be reviewed as they are classified as completed.

Post Restart: For Post Restart CA items assess whether this item was classified correctly as Post Restart or should it be Restart ?

Rollover If a selected corrective action item was rolled over into another CR we need to continue the review of the corrective action item in the CR it was rolled into to determine if the problem was adequately resolved.

Note: Where a Condition Report was generated as a result of NRC findings please note it at the end of your writeup under the status summary. Also, if you reviewed CA items in CRs that are not listed in the table, please add them to the table and note that this is a new item.

General Guidance for Team Review the selected Restart CA items that have been approved/closed. Do not review open CA items. From now on we will review only Restart items The main objective of this Corrective Action inspection is to assess effectiveness of licensees corrective action process to address the findings noted in each corrective action item you review.

Determine if licensee threshold for identification of adverse conditions and prioritization of these findings is appropriate. Are licensees actions to assess the issues to identify the cause(s) and the generic implications, and correct the problem in a timely manner to prevent recurrence appropriate.

Is the licensees audits and assessments process effective in identifying adverse to quality conditions before they reveal themselves and before outside assessments identify the problems.

Are they implementing their corrective action program effectively ? How is it different from before the event ?

Make sure you examine licensee actions to resolve the Big Picture issues and not just individual actions to address findings in each CRs. For example, many CRs and their associated CA items 14

have been issued to document EDG related electrical and mechanical technical issues. Many of these CRs have been rolled over making it difficult to determine if all issues were captured and appropriately addressed. We need to determine if collectively all of the technical Restart issues have been addressed and resolved before they can conclude that all EDGs related issues have been addressed.

If you identify a potential violation, discuss it during the team meetings and make sure you follow the guidance in 0612 (report) and 0609 (SDP) if it applies, have all the information/facts you need to write the violation prior to leaving the site.

You need to provide a writeup for the report, commensurate with each issue you review.

CA-3 of CR 02-04146 covered rework to the degraded condition but was originally identified as post restart. The Team questioned whether this CR was inappropriately closed.

CA-2 to CR 02-4146 required Design Engineering to complete the TORMIS PRA analysis for the Davis-Besse site, including the 50.59. UCN 02-063 incorporated the TORMIS tornado missile probability analysis in the plant design. It concludes, no additional tornado missile barriers required. Because of the low probability of a tornado missile strike determined by TORMIS, CA-3 originally required repair of the missile barrier post restart. Based on the Teams comments, the Licensee has recently changed this CA to repair the degraded missile shields prior to restart.

0 Performance Roll-up (See Davis Besse committed to SR LER-08) NRC to perform evaluation of collective significance of degraded conditions of Containment Air Coolers which have been documented in various CRs.

Lots of work was done here.

The collective significance of CAC issues has been evaluated. These issues included thermal performance degradation, structural degradation of CAC supports caused by boron, and radiological concerns. A question was raised (CATI-0236) regarding justification of acceptability of reduction in thermal performance related to the time it takes to reduce containment accident pressure to 1/2 the maximum value.

Specifically, the time to 1/2 design pressure went from 16.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> to 58.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> with the degraded CACs. This would result in an increase in containment leakage because the pressure stays higher for a longer period of time. Page 14 of collective significance review stated that... exceeding 1/2 containment design pressure within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> has no impact on dose consequences...
