October 15, 2002 TIME:
10:30 a.m. Central ATTENDEES:
J. Grobe C. Lipa W. Dean S. Thomas M. Farber K. OBrien J. Hopkins D. Passehl B. Jorgensen V. Mitlyng J. Collins Agenda Items:
1.
Reports from Staff Marty Farber reported on the status of his activities under the System Health building block, indicating that licensee findings have continued to expand the scope, and a total of 15 common problem areas have been identified. These involve such things as calculation errors, USAR, HELB, and EQ deficiencies. The findings were described as not surprising to the team. Marty indicated that two more weeks of onsite inspection are tentatively targeted for the weeks of 10/21 and 11/4. Marty said Bruce Bartletts team inspection findings (calculation errors, legalistic rationales to avoid or minimize work, and related engineering support concerns) need to be evaluated and factored into the system health arena. Marty indicated the licensees work on latent issues reviews had led to declaring AFW, SW and EDGs inoperable which reflected a proper conservative approach to the findings.
Marty also briefly indicated the re-start testing building block is in an uncertain condition as to when activities will be completed and ready for inspection. The ILRT now appears likely to occur in December, and integrated testing for MODE changes and certain post-maintenance/post-modification testing has not been scheduled yet, either.
Ken OBrien reported on the status of inspection in the Program Compliance building block. His schedule has also been impacted by delays in licensee completion of several program reviews. Ken indicated that he now tentatively plans on a week on site in early November, and another in early December, when licensee progress may be adequate to justify resuming inspection work. The licensees decision-making on the first two areas examined (boric acid control and corrective action) were characterized as hitting the mark, so further NRC inspection in those two areas is not needed. In the area of Quality Assurance, the licensee has decided to do a Phase II review.
Christine Lipa announced, in light of the continuing scheduling uncertainties, a meeting will be arranged for early next week and the entire proposed inspection schedule will be re-examined. Some inspections may be stopped and the results documented, rather
than continue to await developments from the licensee. This includes the system health and program compliance team inspections discussed above.
Site activities (RIO)
Scott Thomas briefed the Davis-Besse Oversight Panel on current site activities noting the following:
The case studies he (Scott) observed both included senior management characterizing the facility status as being beyond the discovery phase and turning the corner to recovery. This does not square entirely with the feedback from inspection teams that discovery is continuing, and the scope of work activities is still expanding.
Some among licensee senior management have also begun to express some frustration about NRC needs not being fully defined, such that the licensee does not know the type and quantity of resources necessary to address those needs.
The research project on the vessel head specimens was an example.
A licensee evaluation of issues identified during the shutdown is being displayed around the plant. It shows 90% are being self-identified and 10% are being NRC-identified.
Work to restore the startup transformer is continuing with a target completion date of 11/17.
Both emergency diesel-generators remain inoperable but available with exhaust system upgrades to provide tornado missile protection targeted to be complete by 10/23.
Review of action items (panel)
The panel reviewed the list of open action items, with discussions and actions as follows:
Item 71 was discussed. NRR forwarded a draft report with the results of the review of the licensees Revision 1 to the Technical Root Cause. The draft report is being reviewed, with some discussion regarding whether it is conclusionary enough. The report will be made final once any comments are received and considered.
Item 72 was discussed. The LLTF report has been received and is being reviewed so as to extract any observations impacting the Oversight Panel. Christine Lipa will attend the LLTF public meeting at the plant on November 6, then plans to meet with the LLTF personnel present the following day to ensure a full understanding of the observations, so they can be addressed in an appropriate manner.
Item 74 was discussed. The subject matrix document remains incomplete/unofficial, but it is getting pretty close.
Item 82 was discussed. This is related to Item 72 and ensuring the Panel understands the observations and context of the LLTF.
Item 85 was discussed. The Office of Research continues to evaluate the need for additional study of additional specimens from the old vessel head. The continuing open status of this item is impacting our plan to update the CAL and remove the line item related to the quarantine.
Item 99 was discussed. Work on this item is expected to be completed soon.
Item 112 was discussed. The monthly public meeting date for December (10 or 11) is still being finalized. Jack Grobe expressed a preference for Tuesdays, both in December (the 10th) and in the months thereafter. Christine Lipa also has the action to pursue the scheduling of dates for possible additional meetings in January, February and March 2003.
Item 114 was discussed. No new news on a potential site visit by Brian Sheron - Jon Hopkins will continue to follow developments.
Item 120 was added. Jon Hopkins will follow up on a request from the ACRS for an update (reportedly in early November), to determine what the needs of the Committee are and what their exact schedule is. He will report this information back at a future meeting of the Panel.
Licensing Issues/Actions (DLPM) - status sheet The status of Davis-Besse licensing activities and ticket tracking was presented by Jon Hopkins:
The 2.206 petition response letter remains in management concurrence; it could be signed out as early as today (10/15) or tomorrow.
Work on the code relief and license amendments relating to use of the Midland reactor vessel head has continued with no significant issues identified so far.
No new green ticket activity of note.
2.
IMC 0350 Panel Business Inspection Schedule The Panel once again had extensive discussions of inspection scheduling, since the schedules for several inspections remain unsettled. The date(s) when the licensee will have sufficient information to justify further inspection activities remains unclear. The Oversight Panel expects to have a special meeting early next week to consider how to manage resources and scheduling in light of limited licensee information.
Process Plan Dave Passehl has updated and distributed a revised Process Plan, requesting any comments or other feedback preparatory to a detailed discussion of the Plan at the Panel meeting scheduled for 10/22.
Restart Checklist - Investigations Two proposed additions to the NRC restart checklist were discussed. These were an item on the radiation protection program and one on containment sump issues. The focus in radiation protection was characterized as being on occupational exposure control and related work planning - derived from the special inspection of potential over-exposures from intake of alpha-emitting isotopes. The Panel will look to approve the revised checklist next week.
Licensee Return to Service Plan No new discussions.
3.
NRC/Licensee weekly calls No call this week, due to monthly public meetings at the site on Wednesday, 10/16.
4.
Utilization of the Web Page Jon Hopkins will post items on the Web Page this week, in Steve Blooms absence. A couple of sets of meeting transcripts have been entered into ADAMS and sent to NRR to be posted.
5.
Future Activities/Plans/Meetings Next panel meeting: Tuesday 10/22 at 2:00 p.m. EDT, 1:00 CDT Monthly allegations briefing to be added to agenda.
6.
Discuss how to handle public or staff comments, questions, allegations, and concerns received by phone, fax, letter, email, or at public meetings.
Potential issues which may arise at tomorrows meetings, either with the licensee or with the public, were discussed. The issues could include: concrete spalling and associated repairs; stains on the reactor vessel bottom head; scheduling (FENOCs and NRCs);
and Congressional (2.206 Petition, Sen. Voinovich) interest and developments.
