SUBJECT:

MINUTES OF INTERNAL MEETING OF THE DAVIS-BESSE OVERSIGHT PANEL The implementation of the IMC 0350 process for the Davis-Besse Nuclear Power Station was announced on April 29, 2002. An internal panel meeting was held on December 17, 2003. Attached for your information are the minutes from the internal meeting of the Davis-Besse Oversight Panel, and the Open Action Items List.

MEETING MINUTES: Internal IMC 0350 Oversight Panel Meeting Davis-Besse Nuclear Power Station DATE: December 17, 2003 TIME: 7:00 a.m. Central ATTENDEES:

J. Grobe W. Ruland S. Thomas C. Lipa A. Mendiola J. Persensky R. Baker J. Hopkins L. Jarriel G. Wright R. Skokowski Agenda Items:

1. Discuss/Approve Todays Agenda The Panel approved the agenda, but modified the order of presentations. THE APPROVED AGENDA REFLECTS THE ORDER LISTED IN THESE MINUTES.

2. Discuss Plant Status and Inspector Insights and Emergent Issues List S. Thomas led a discussion of plant status and inspector insights and emergent issues.

The plant is in Mode 5, 100oF and 130 psig, with a bubble in the Pressurizer. The licensee is performing control rod testing to verify rod latching capability and rod position indication.

The licensee has identified that DH61, the decay heat isolation valve from train 1 to purification, is leaking past the closed valve seat, allowing the downstream relief valve to lift. This condition is preventing venting the reactor coolant pumps. A problem-solving decision-making team is investigating possible courses of action.

3. Discuss RRATI Assessments on Continued Observations of Mode Change and Restart Potential R. Skokowski briefed the Panel on the RRATI team member assessments on continued observation of licensees Mode change and heatup evolutions, and readiness for restart.

The team is split on assessing readiness for restart, with only 1 of 4 members currently supporting restart. The members agree unanimously that more observations of operational performance are required to fully assess readiness for restart. Two new observations since yesterday were:

1) An observed post maintenance test (PMT) performed on the service water system following modification from the water hammer event. The PMT included stroke time testing of the inlet isolation valves. The operator stroked the valve shut for the time test. The valve shut properly, and then immediately re-opened.

This was due to the existing logic, which had not been altered by the system modification, requiring the valve to be open if the room fan was running. This condition was not identified during the pre-job brief because the operators were using only a part of a preexisting procedure to perform the PMT. Deficiencies

identified as a result of this performance were inadequate post mod PMT procedure development, operator knowledge, and management expectations.

2) An observed just-in-time training session on plant heatup procedures. An SRO had a concern with the heatup procedure being used. If the heatup limits were followed as given in the procedure, it would have the operator violate the reactor coolant pump minimum NPSH curve. This condition was identified by the licensee, but was not identified during previous required procedural reviews.

R. Skokowski summarized the brief with the teams conclusion that if the RRATI was terminated today, the team would not be comfortable recommending restart based on observations to date.

4. Discuss the Need for a Followup RRATI Based on Licensee Performance Observed to Date by Current RRATI The Panel discussed the ability to close Restart Checklist Item 5.c, based on the RRATI observations and assessments to date, and concluded that a second RRATI would be required to assess licensee performance before any Panel discussion on closure of Restart Checklist Item 5.c could occur. The Panel also concluded that, as a minimum, a meeting with the licensee to discuss why the licensees corrective action implemented following the 1st Mode 4 change were not fully effective.

NEW ACTION ITEM (230) - J. GROBE TO DEVELOP ACTION PLAN FOR DOCUMENTING BASIS FOR PATH FORWARD WITH LICENSEE BASED ON CURRENT INSPECTION RESULTS AND READINESS FOR RESTART, TO INCLUDE PROCESS FOR INFORMING LICENSEE.

The Panel further decided to terminate the remaining around-the-clock coverage as the Mode change is expected to be significantly delayed.

5. Brief Panel on results from the Management and Human Performance Phase 3 Inspection G. Wright led a review of the Management and Human Performance Phase III inspection results. The five key elements of the inspection plan were:

1) Internal Safety Culture Assessment - The licensees plan is acceptable with further attention in some areas required. This plan is not used elsewhere in the industry, so this demonstrates excellent initiative.

2) External Safety Culture Assessment - Basically the same assessment as above, and it should be noted that the plan compares well with international guidance and programs.

3) Integration of Internal and External Safety Culture Assessments - Looked at a comparison of the PSHA assessment and Davis-Besse assessment results.

4) SCWE and SCWERT - Monitoring system in place, used as input to the Integrated Readiness to Support Restart report, and better than most utilities.

Employees understand responsibility to raise safety issues, how to report them, and are not fearful of retaliation. Majority trust supervisors, but not managers, to act on the information.

5) Employee Concerns Program - Significant improvement over the Ombudsman Program, with more concern going into the program.

The Monitoring and Effectiveness Assessment element of the inspection was not specifically broken out for the final report/exit.

The team concluded that all processes are in place to adequately support effectiveness in correcting deficiencies identified.

6. Panel Review Restart Checklist Item 4.b, Effectiveness of Corrective Actions in the Adequacy of Organizational Effectiveness and Human Performance area, for Remaining Closure Criteria G. Wright led a discussion on moving forward with closure of Restart Checklist Item 4.b.

The complete Management and Human Performance Phase III inspection team met yesterday. All members concur and cannot recommend closure of Restart Checklist Item 4.b or recommend restart of the plant at this time. This is based on review of the SCWE/SC results and other inspection activities completed. The team concluded that the corrective actions have not been fully effective in addressing noted deficiencies.

Again, as with the RRATI results, the Panel concluded that the licensee needs to explain why corrective actions to date have not been effective, define effective corrective actions and present its assessment of the different corrective actions, and the NRC will inspect the results.

7. New Action Items One new Action Item was added to the open action items list. THE UPDATED OPEN ACTION ITEMS LIST IS ATTACHED TO THESE MINUTES.
