MEETING MINUTES:
Internal IMC 0350 Restart Panel Meeting Davis-Besse Nuclear Power Station DATE:
November 19, 2002 TIME:
1:00 p.m. Central ATTENDEES:
J. Grobe D. Passehl T. Mendiola G. Wright B. Dean S. Thomas C. Lipa D. Simpkins J. Hopkins J. Collins Agenda Items:
1.
Discuss Plant Status and Inspector Insights Reactor Coolant System (RCS) is in a deep drain condition with levels at 10" above the hot leg centerline. Approximately 80 valves are scheduled for maintenance during this arrangement of the RCS.
Decay Heat Valve Pit modification remains in the design phase. Licensee contractor support will provide a streamlined package for a timelier completion of the project. That report is expected Friday.
Resident Inspector exit on the previous Thursday. A 50.70 potential violation and improper evaluation of a Licensee Event Report were two issues presented.
Two new LERs were opened, the Emergency Sump and Diesel Generator Tornado Missile Shield issues.
2.
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.
With the information available, the inspection team was able to review parts of the Root Cause report and found the work partially successful. Additionally, the corrective actions were graded fair in the initial consideration of the inspection team. An integrated assessment was not conducted, and no procedure was found to perform an integrated assessment. These facts concerned members of the inspection team.
Davis-Besse Oversight Panel (DBOP) had active discussion on the inspection necessities for oversight responsibilities. B. Dean centered the dialog on additional inspection required for the DBOP to perform its assessment. G. Wright provided
feedback that issues in engineering had not been addressed to the inspection teams satisfaction. The discussion concluded with the DBOP expecting to review the summary report of work completed to date by the inspection team.
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.
A formal exit meeting for the first report will be held during the 2nd week in December.
The inspection team expects to be at the site for the 2nd or 3rd week in January to complete phase 1 of the inspection.
3.
Discuss Restart Checklist The Davis-Besse Oversight Panel (DBOP) discussed the proper method of assimilating the complete and accurate information issue into the Davis-Besse oversight process. A proposal was made to incorporate the issue as a separate entry in the Restart Checklist.
The proposal was supported by a general discussion of the criteria under MC 0350 for addition to the restart checklist and the possible severity rating for the complete and accurate information issue. Three of four criteria under the MC 0350 procedure for item addition to the Restart Checklist were identified as being met by this issue. The issue resulted in a cited violation. The issue resulted in a loss of the licensees ability to maintain and operate the facility in accordance with the design and licensing basis. The issue resulted in a condition in which NRC management lacked reasonable assurance that the licensee can or will conduct its activities without undue risk to public health and safety. The severity of the issue potentially prevented the issuance of an order which would indicate an escalated enforcement action. These items, identified by the proposer, demonstrated that the complete and accurate information issue meet criteria for inclusion as a separate line item into the Restart Checklist.
The proposal was debated. The dissenting opinion was focused on difficulty to ensure that the issue will not reoccur, questions whether the issue would not have prevented degradation and public confidence in the NRC disposition of the issue.
A question was raised on the method the NRC would enact to ensure the licensee would provide complete or accurate information in the future. Difficulties in presenting and inspecting this method were discussed.
Questions on the effects of the complete and accurate information issue on the actual degradation of the reactor vessel head were raised. Individuals believed that although the issue did add to the depth of the degradation finding, it was not a contributor to the physical degradation of the head. The proposer stated the opinion that the issue had a significant role in leakage and degradation discovery, and merited inclusion to the checklist.
A question of public confidence in the overall disposition of this item was raised. An individual questioned the perceived effect of resolving part of the issue prior to the Office of Investigation completing its efforts in this area. The effects to the public perception within the issue of inaccurate or incomplete information might present NRC acceptance prior to complete NRC disposition of the issue. The proposer countered that while the OI investigation was ongoing, formal results may not be expected for a
year or two. Further, the issue could be separated from its willfulness aspect to assure the public that action was being pursued and public confidence would be increased.
Final resolution to the proposal was not reached. A recommended action from the dissenter of the proposal was inclusion of the item in the Restart Action Matrix or that the item was already fully covered by items from the AIT followup report. The item will be discussed during the 12/3 Davis-Besse Oversight Panel internal meeting.

5.
Discuss Restart Action Matrix The DBOP discussed what constitutes criteria for items to be added to the Restart Action Matrix (RAM). The effective use of the RAM was instituted as a punch list to ensure items were properly covered and documented. The items for inclusion were to be one step below items within the Restart Checklist. The categories of items were discussed as inspection unresolved items, licensee event report items requiring follow-up actions, significant findings and internal findings of the licensee. A discussion on the breath of these categories was discussed, but final agreement was not reached.
Further discussion expected in the next internal DBOP meeting.
6.
Discussion of Licensing Issues and Actions
An update was presented on licensing issues to the Davis-Besse Oversight Panel.
A.
MB1679, 4-1-01, Allows eight hours for SFAS & SFRCS channel functional testing before declaring channel inoperable. The technical specification branch is reviewing this item. Purpose is to ease surveillance. This is not a restart item.
B.
MB1689, 3-30-01, ECCS issue which the licensee is going to withdraw due to Decay Heat Valve Pit modification rendering this change unnecessary.
C.
MB3280, 10-12-01, 1.63% power uprate request is on hold due to NRC request for additional information. This item is not expected to be approved prior to restart.
D.
MB3281, 10-9-01, SFRCS instrumentation item will be withdrawn by the licensee to revise their submittal.
E.
MB3746, 12-17-01, Item deletes one Technical Specification action when single RPS channel is inoperable. Licensee sending in additional information at the end of November. This item was identified as a standard request and not a restart item.
F.
MB3749, 11-30-01, Reduce Pressurizer high level limit from 305 to 228 inches.
Licensee has been operating with an administrative control of 228 inches. After DBOP discussion on this item, decision reached to check this item through inspection prior to restart. The item should be tracked using the Restart Action Matrix.
G.
MB3843 and MB3909, 1-11-02, IST 3rd 10-year program. Licensee due to submit additional information. This is not a restart item.
H.
MB5283, 6-4-02, TSTF-358, Rev 5, Revise requests for missed technical specification surveillance. This is not a restart item.
I.
MB5848, 8-1-02, Relief requests A26 & A27. This item required for restart.
J.
MB5849, 8-1-02, Relief request A2. This item required for restart.
Items 9 and 10 were noted to be under review by Dave Hills branch for allegation correlation. DBOP informed reviewers of sensitivity of these licensing issues.
7.
Discuss Items for Licensee Weekly Calls No items discussed 8.
Discuss/Update Milestones and Commitments Davis-Besse Oversight Panel (DBOP) discussed the Quarantine Letter for the old reactor vessel head and head cutout sample in BWXT facility in Virginia. Region III personnel requested that NRR and RES determine their requirement for a release free
and clear or a requirement to ensure licensee will complete Phase III analysis prior to release.
The DBOP discussed the Technical Root Cause problems which were still under development at NRC Headquarters. A decision may be required to formally differentiate what the DBOP needs verses NRRs needs.
The meeting on Monday between region III personnel and the licensee on the potential overexposure was discussed. A disagreement still exists between the NRC and licensee on the value of the overexposure. The input parameter for the air the individuals inhaled is the question of interest. All doses are normalized to equivalent Co-60. The scaling factors for this normalization must be determined. The licensee approach was found interesting by NRC staff, but not logical. This approach caused a difference from the licensees finding of 5 Rem to the NRCs 80 Rem.
Upcoming meetings with the licensee on November 26, 2002 were discussed. The morning meeting is to cover the new sump design. Item on restart checklist but the NRC not required to approve this modification. The afternoon meeting is to discuss the incore nozzle potential leakage issue. The NRC asked for this meeting, invited Framatome and notified other B&W owners about the meeting. The purpose of the meeting will be Davis-Besse specific.
The ACRS briefing on Davis-Besse issue is scheduled for December 5, 2002. J. Grobe, B. Dean, A. Mendiola and J. Hopkins from the DBOP are expected to attend.
