Internal IMC 0350 Oversight Panel Meeting Davis-Besse Nuclear Power Station DATE:
December 10, 2002 TIME:
10:00 a.m. Central ATTENDEES:
J. Grobe K. McConnell B. Dean J. Hopkins C. Lipa J. Jacobson D. Simpkins J. Collins S. Thomas D. Passehl G. Wright Agenda Items:
1.
Discuss Plant Status and Inspector Insights Reactor coolant system (RCS) is in a deep drain condition. Current level is at 10" above the hot leg centerline. Seventy-four valves are scheduled for maintenance during this arrangement of the RCS. Fifty-five are complete with the remaining items delayed due to parts availability.
80% failure of welds between the tubes to tubesheet in the feedwater preheater 1-6. Licensee is evaluating the cause.
Three individuals had identified dose rate alarms with no actions taken. Item is under review by licensee.
Electrical and diesel fire pumps inoperable. Licensee considered bringing in new temporary pump, but availability of diesel fire pump at low lake temperature was analyzed as a preferred method.
Axial cracks were identified in two of the four thermosleeves for high pressure injection paths into the reactor coolant system. The two cracked thermosleeves are downstream of HP-58 and HP-59. The remaining two thermosleeve boroscope images were reviewed by Framatome and no indications were found.
Licensee plans to replace the two cracked thermosleeves.
System Reviews are expected to be complete this week. All 5 of the latent issue reviews were performed by the old Engineering Assessment Board (EAB) and considered to be good reviews. The old EAB did review and approve the scope of all 31 system reviews. Approximately 15 of the system reviews were reviewed and accepted under the old EAB. Twenty-three system reviews generated comments from the old EAB. Eight system reviews were not reviewed by the old EAB. The new EAB will not review the remaining system reviews.
Concerns were raised by Davis-Besse Oversight Panel members about the consistency in quality of review by the new EAB and the new EAB procedures. Henry Stevens was positioned as the new EAB Chairman. This choice was questioned due to Mr. Stevens being the QA Manager that reviewed the reactor vessel head inspection during the 2001 outage. Further the system engineers responsible for the remaining unreviewed system reviews did not have a review that went through the old EAB review process. Jim Powers and Lew Myers have final approval now for system reviews after the old EAB was disbanded.
Jack Grobe presented a summary of a meeting between Davis-Besse Oversight Panel personnel and Licensee engineering management and staff. In the meeting 560 condition reports under System Health category were identified as mode restraints. 77 of these condition reports declared equipment inoperable. 29 of these issues were identified for significance. J. Grobe asked the licensee to clarify the issue of significance and operability. A definition for operability was agreed upon, equipment that does not meet a specific requirement in technical specifications or prevents performance of its purpose during accident mitigation. The licensee identified a process to scrub condition reports for operability issues.
The DBOP had remaining concerns on the design issue review and the significance issue review. The DBOP has requested the licensee to hold a public meeting, tentatively scheduled for December 23, 2002, to justify extent of condition review.
Essentially if design reviews identify operability issues, why will all systems not be under review.
Contractor reduction in force has occurred over the previous week. Most engineering support contractor workers were released. All contract NRC inspector interface staff were released. Communications issues on inspections have arisen due to the recent downsizing. The DBOP is working to identify the issues and resolve them.
J. Grobe provided a summary of a meeting he had with Lew Meyers. L. Meyers provided themes for the upcoming public meetings; licensee making progress, discovery is over, find and fix mode, core reload mid January, discuss lower head inspections and emergency sump modification and manager observation program results. J. Grobe asked L. Meyers several questions, specifically on the issue of how to determine if safety culture has changed. Questions were asked about the loss of credibility with the public due to the safety culture and the possibility of an independent contractor to track issues. L. Meyers concluded his themes for the public meetings with a desire to present that Davis-Besse would not be a financial black hole for FirstEnergy Corp.
J. Grobe attended the licensee Reactor Oversight Panel (ROP) meeting. He noted a difference in the tone of the meeting. It was less intrusive and more cost focused.
1.a Discuss Management and Human Performance Inspection Geoff Wright presented to the Davis-Besse Oversight Panel the status of the Management and Human Performance Inspection. The inspection team was on site in October but was unable to fully complete the inspection due to the licensee being incomplete on several topics. The Operations and Off-Site Committee Root Cause
reports were not available for the October inspections. The Engineering Root Cause report was added by the licensee on suggestion by the inspection team.
G. Wright informed the DBOP that a formal exit for the work completed in October was scheduled for December 18, 2002. Two items were presented as the focus for the exit.
Licensee reviews completed to date were meaningful, but the overall approach was not sufficient to determine if all errors could be found. The Operations, Off Site Observation and Engineering reviews were not complete for review. The DBOP noted that the operations report was just completed, but G. Wright informed the panel that it would not be covered in this exit.
J. Grobe noted that the Operations Root Cause report was discussed in the licensee ROP meeting. He noted that the comments made about the report, marked it as not balanced with not enough supporting data.
G. Wright updated the DBOP on the future activities of the inspection team. A partial inspection report would be completed for DBOP review on activities completed to date.
The inspection team expects to be at the site for the 2nd or 3rd week in January to complete phase 1 of the inspection.
1.b Confirmatory Action Letter Update John Jacobson asked about the status of the Confirmatory Action Letter (CAL) Update.
The document itself was still under review by C. Lipa. The DBOP noted that Sam Collins approval would be required prior to issuing this document.
A discussion was held on the CAL items that could be modified or closed.
The quarantine item could be conditionally closed.
Quarantine components or other material from the RPV head and CRDM nozzle penetrations that are deemed necessary to fully address the root cause of the occurrence of degradation of the leaking penetrations. Prior to implementation, plans for further inspection and data gathering to support determination of the root cause will be provided to the NRC for review and comment.
The root cause item could be partially closed.
Determine the root cause of the degradation around the RPV head penetrations, and promptly meet with the NRC to discuss this information after you have reasonable confidence in your determination.
The extent of condition issue needed to be rewritten.
Evaluate and disposition the extent of condition throughout the reactor coolant system relative to the degradation mechanisms that occurred on the RPV head.
The head replacement item could not be closed until the relief requests on the reactor vessel head are approved.
Obtain NRC review and approval of the repair or modification and testing plans for the existing RPV head, prior to implementation of those activities. Prior to restart of the reactor, obtain NRC review and approval of any modification and testing activity related to the reactor core or reactivity control systems. If the reactor vessel head is replaced in lieu of repair or modification, the replacement must comply with appropriate Commission rules and industry requirements.
The licensee determination of safety significance item could be closed.
Provide a plan and schedule to the NRC, within 15 days of the date of this letter, for completing and submitting to the NRC your ongoing assessment of the safety significance for the RPV head degradation.
The DBOP determined additional review was necessary prior to drafting the modifications or closures.
2.
Discuss Action Items Item 54a:
On the TSP Allegation, B. Dean believed B. Bateman thought a calculation for sufficient volume of TSP was completed to technical specification value. However some members of the DBOP questioned whether the calculation was to technical specification or actual TSP level at Davis-Besse.
Item 54b:
On the generic question of TSP technical specification requirements including the effects of maximum allowed leakage, several methods for resolution are still under consideration. B. Bateman was deemed the responsible party for this investigation, which now falls outside the purview of the DBOP.
Item 83:
Item Closed.
Item 85:
Item reassigned to J. Jacobson. Discussion on draft letter in Section 1.b above.
Item 88:
Update item with date of receiving TIA, December 6, 2002.
Item 113:
Discussion on procedure for maintaining UCS representative on service lists. A DBOP member indicated that due to proper procedures, the UCS representative would be removed 90 days after the DD was issued, 09/24/02. Several DBOP members requested that the UCS representative remain on the service lists to ensure public confidence in the DBOP activities. Communications with the Office of Public Affairs were deemed necessary to secure this activity.
Item 121:
The DBOP wished to close this item through the meeting summary of the 11/26/02 public meeting discussing the Undervessel Nozzle possible leakage. In the meeting summary, the request was made for a statement setting forth that the NRC understands the NOP/NOT leak test plan and has no outstanding concerns. Further that the leak test mockup and test
itself should provide a reasonable assurance for a qualified leak test. B.
Dean took responsibility for this item.
Item 127:
A time for completion of this decision was requested. J. Hopkins is taking the lead on this issue.
Item 128:
Item Closed.
New Item 129:
Survey NRR and Headquarters management for possible future Davis-Besse site visits or tour requirements. J. Hopkins is taking the lead on this issue.
New Item 130:
Determine actions for Davis-Besse end-of-cycle meeting and senior management briefings. C. Lipa is taking the lead on this issue.
3.
Discussion of Licensing Issues and Actions No new items were discussed, with the exception of those noted in Section 2. Action Items, above.
4.
Discuss/Update Milestones and Commitments T. Kozak to have a SERP on 12/12/02 on the worker overexposure issue.
