MEETING MINUTES: Internal IMC 0350 Oversight Panel Meeting Davis-Besse Nuclear Power Station DATE: October 8, 2002 TIME: 1:00 p.m. Central ATTENDEES:

C. Lipa T. Mendiola W. Dean S. Thomas M. Farber K. OBrien J. Hopkins B. Bartlett G. Wright D. Passehl B. Jorgensen M. Holmberg Agenda Items:

1. Reports from Staff Report by Mel Holmberg on Vessel Head and Containment Inspections The inspection of head resolution (IR#007) is complete and the report is being assembled. Several parts are involved: Don Jones looked at NDE on the head welds, done at the Midland site, and no deficiencies were identified. Richard McIntyre of NRR did code data-package review and determined the licensee had established that the Midland head meets the code (with defined exceptions being evaluated by NRR) and the N stamp remains valid. The containment cutting and restoration were inspected by Mel and John Jacobson, including work requests and work in progress. Surface voids occurred in the concrete pour to restore the shield building which had not been resolved at the conclusion of the inspection. Overall, there were no findings identified, but several observations were made.

The (second) inspection of the containment extent of condition (IR#012) is also complete and the report is being assembled. The report of the first inspection (IR#009) has been issued - it showed the licensee had not succeeded in its objectives and reported findings in: 1) lack of acceptance criteria or requirements to follow inspection plans, and 2) training and qualification of personnel performing the reviews. The licensee re-performed the inspections under the containment health building block.

Mels second inspection did not identify any findings. There were some items for which too little information was available to permit final conclusions. The sample size regarding corrective actions was small, and the inspection of electrical components was limited to a few motor-operated valves. Also, the cause and consequences of boric acid and rust streaks at the bottom of the reactor vessel had not been established. The report will contain an action item to evaluate licensee results in following up on these issues.

A formal exit on both of Mels inspections is tentatively set for 10/24 at the site.

Marty Farber reported on the status of his activities under the System Health building block. He indicated that two weeks of work remain and the licensee's progress in preparing packages has been slow, so his inspection cannot be completed by 11/8.

Thus far, only two packages have been completed for inspection, which is a too-small sample. The volume of items in the licensees corrective action program has continued to grow; development of corrective actions has not kept pace with identification of issues. The Panel discussed the potential need for Marty to return his Inspection Plan to the Panel for re-evaluation. Marty has arranged his schedule to continue to support the Oversight Panel through November.

Bruce Bartlett reported on the status of his team inspection of design/engineering of three systems, in support of the System Health building block. The three systems have been identified (service water, high pressure injection, and 4160 V a.c.) and the licensee has provided information as it became available, such that this inspection should finish on 10/11. Issues were identified in all three systems, including operability issues in the service water system. All the issues are in the licensees corrective action system. A formal exit will be scheduled in about two weeks.

Geoff Wright reported on the status of his inspection activities in the Management and Human Performance building block. He said the team had some difficulties in some of the cases examined, due to unclear connections between cause and corrective action.

In addition, the Operations, Quality Assurance and Offsite Review arenas were examined outside the MORT technique which was used for the other areas, and they are incomplete or (in the case of Operations) have been withdrawn and will be re-done. Geoffs inspection activities were characterized as being at a standstill pending licensee development of additional information. Geoff will evaluate the status of the licensees schedule later in the week when he is on-site; he may choose to terminate the inspection and document it, with the remainder of the work to be done in a second inspection at a later date, or he may suspend the inspection temporarily and resume later.

Ken OBrien reported on the status of his teams inspection in the Program Compliance building block. His schedule has been significantly impacted by delays in licensee completion of several program reviews and upgrades - he will not finish by 10/11 as originally planned. The licensee appears unlikely to complete more programs to the point we need for our reviews until about 11/1. Ken estimated sufficient progress may be made to justify resumption of inspection activities in late November, with work continuing into or through December.

Site activities (RIO)

Scott Thomas briefed the Davis-Besse Oversight Panel on current site activities noting the following:

  • There were four separate building-block inspections in process at the site during the week, in addition to the resident inspectors activities.
  • The special inspection team to review the potential occupational over-exposure due to inhalation/ingestion of transuranic isotopes was on-site and active. A site debrief was set for 10/10.
  • Jim Dyer and Sam Collins were visiting the site on 10/8 and 10/9, planning to tour and to meet with managers and (separately) with licensed operators.
  • The old service structure was welded on the new reactor vessel head.

Welding was the only option, since the bolting alignments didnt match.

Review of action items (panel)

The panel reviewed the list of open action items, with discussions and actions as follows:

Item 26 was discussed. The item remains on hold awaiting developments in the licensees schedule - licensee schedule slippage is impacting the ability of the Oversight Panel to marshal inspection resources effectively and efficiently.

Item 71 was discussed. NRR will forward to RIII (C. Lipa) the report of its review of the licensees Revision 1 to the Technical Root Cause.

Item 72 was discussed. The LLTF report will be available for review and extraction of observations needing specific Panel action on 10/9. The LLTF is looking to schedule public meetings at or near the plant on November 6.

Item 85 was discussed. The memo from NRR to RIII concurring in release of the quarantine by RIII was with Tony Mendiola, at the start of the concurrence review.

Item 89 was discussed. The feeder report had been received. The item is expected to be closed after some follow up by Tony Mendiola to verify nothing additional is due.

Item 103 was discussed. The actions were believed to be complete, but Bill Dean took the action to verify RES was included in the inquiry.

Item 104 was discussed and closed; action was completed.

Item 111 was discussed and closed; action was completed.

Item 112 was discussed. Monthly public meeting dates are set for October 16, November 13. December date (10 or 11) being finalized. Christine Lipa now has the action to pursue the scheduling of dates for possible additional meetings in January, February and March 2003.

Item 114 was discussed. A potential site visit by Brian Sheron remains to be scheduled

- Jon Hopkins will follow up - due 10/15.

Licensing Issues/Actions (DLPM) - status sheet

The status of Davis-Besse licensing activities and ticket tracking was presented by Tony Mendiola and Jon Hopkins:

  • The EDO has requested a package of information regarding the follow up special inspections on the contamination events and the potential internal exposures.
  • The Tauzin/Gillmor congressional committee terminated its review of Davis-Besse related issues unexpectedly, with NRC still owing some information to the committee. NRR finished assembling the requested information and the information package was in concurrence.
  • The 2.206 petition response letter is in management concurrence.
  • The EDO has requested that a frequently asked questions package be prepared and put on the NRC website. NRR is assembling the requested package.
  • 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.
2. IMC 0350 Panel Business Inspection Schedule The Panel had extensive discussions of inspection scheduling as part of the receipt of reports of inspection activities discussed above. The schedules for several inspections remain unsettled. The date(s) when the licensee will have sufficient information assembled to justify further inspection activities are not clear. The Oversight Panel expects the inspection team leaders to work diligently with their licensee counterparts to acquire best estimates, and to report the information to the Panel. A higher-level discussion with more senior licensee management is under consideration.

Process Plan Dave Passehl is updating the Process Plan, based on detailed discussions at a separate meeting on 10/4. Among other things, the revised Plan will merge in the proposed Project Management Summary, as discussed at the Panel meeting of 10/1.
