y Millstone Unit 2 ICAVP Final Report - Supplement 1.
Corrective Actions Review - Level 3 Discrepancy Reports At the time of the issuance of the Millstone Unit 2 Independent Corrective Action Verification Program Final Report - Volumes I and II (NUM2-PPNR-2248-L, dated January 12, 1999),
NNECo had not completed the corrective actions associated with the Significance level 3 Discrepancy Reports generated by Parsons. The engineering activitics associated with these corrective actions have now been completed by NNECo and Parsons has completed the review of a selected sample of these corrective actions. The purpose of this supplement to the Final Report (Volume II - Section 6.3) is to document the results of this review.
1.1.
Level 3 Discrepancy Report Sample From th: total population of seventy-five (75) confirmed Significance Level 3 Discrepancy Reports, the NRC selected a sample of thirty (30) corrective actions for Parsons to resiew. The j
following corrective actions were selected:
DR Number System / Program / Discipline DR-0030 AFW - Structural DR-0033 Inservice Testing - Mechanical DR-0104 EEQ - HELB - Piping DR-0113 HPSI-Mechanical DR-0119 HPSI-Piping DR-0127 Setpoints - Control Systems DR-0158 Setpoints - Control Systems DR-0203 HPSI-Mechanical DR-0350 HPSI - RWST - Control Systems DR-0417 Pump and Valve Testing - Mechanical DR-0422 HPSI-Control Systems DR-0426 RRC - Mechanical D.R-0481 HPSI - Piping DR-0505 Various - Piping DR-0508 Setpoints - Control Systems DR-0549 EDG - Electrical DR-0573 Fuse Control - Electrical
_Q,R-0578 AFW - Mechanical DR-0610 EDG - Mechanical DR-0618 EDG - Electrical DR-0658 Serpoints - Control Systems
DR Number System / Program / Discipline DR-0680 E!cetrical Separation - Electrical DR-0685 Accident Analysis - Mechanical DR-0704 AFW - Control Systems DR-0712 Electrical Separation - Electrical DR-0747 Auxiliary Feedwater - Mechanical DR-0759 Accident Analysis - Mechanical DR-0770 AFW - Mechanical DR-0802 AFW - Mechanical DR-0814 Accident Analysis - Mechanical 1.2.
Level 3 Discrepancy Report Corrective Action Sample
- Results The purpose of the Significance Level 3 Discrepancy Report Corrective Action review was to assure that NNECo has taken the appropriate steps to correct the Significance Level 3 (Licensing i
and Design Basis) issue that was identified in the DR. Closure packages were assembled by NNECo for Parsons review for each of the selected Discrepancy Reports.
j l
The review concluded that adequate corrective actions were developed for the licensing and design basis issues by NNECo for twenty-nine (29) of the thirty (30) closure packages. In one DR closure package, NNECo did not include vent and drain valves, which were added as part of the l
modification, to the appropriate leakage testing procedure. This was a minor completeness issue and a Condition Report was generated by NNECo to track and correct this item. All other technical aspects of this DR were reviewed with satisfactory results.
1.3.
Level 3 Discrepancy Report Corrective Action Review
- Conclusions Based upon the results of the Significance Level 3 Discrepancy Report Corrective Action resiew, the NNECo Corrective Action Process is effective in correcting the Licensing and Design Basis issues.
1.4.
Overall Conclusions Based upon the lack ofidentification of any significant Licensing and l}esign Basis issues in any of the three scopes of Corrective Action review, it is concluded that the NNECo Corrective Action Process was effective in identifying and correcting Licensing and Design Basis issues. Therefore, the Corrective Action review conclusions presented in Section 1.4.4 of Volume I remain unchanged.
Section 1.5 of Volume f (Overa!! Conclusions) remain valid.
