MDIORANDUM FOR: C. E. Norelius, Director Division of Projects and Resident Programs FROM: R. L. Spessard, Director Division of Enginearing ,

SUBJECT:

INSPECTION PLAN FOR COMPLETING BYRON REINSPECTION PROGRAM Attached is the plan for completing our inspection of the Byron Reinspection Program. This plan is based upon previous inspection results; upon our review of the "Report on the Byron QC Inspector Reinspection Program" February, 1984 received on February 24, 1984; and, upon discusal,ons held with DPRP. Further, I believe this plan is responsive to Part 2, Items 1 through 7 of the Hayes memorandum to me dated February 13, 1984.

A significant inspection effort was expended in l'983 to monitor the Reinspection Program while it was in progress (7 inspectiqn reports by DE (4) and LPRP (3)).

This, when added to the attached Inspection Plan, gives adequate assurance thL.

Commonwealth Edison conducted the program in accordance with their ple.n, and that the program results indicate that the inspector certification deficiencies did not result in significant quality problems going undetected.

D e attached inspection plan (consisting of items 1 - 10) references pertinent sections of the Reinspection Program Report. nose DE inspectors who have par-ticipated in our inspections have reviewed or will review Item 8. Mr. Ward is reeponsible for Items 1, 2, 6, 9 and 10. Mr. Muffett is responsible for Items 3, 4, 5 and 7.

The inspections will be completed by March 16, 1984' for those efforts which have been completed by the licensee. Some of the items, according to the Reinspection Report, may not be completed yet, but will be inspected as soon as the item is complete. As we have in the past, we will continue to coordinate j closely with DPRP representatives during the completion of this effort.

If you have any questions on this matter, please let me know.

4 BYRON INSPECTION PLAN

1. Review the Hatfield computerized data base established to reconcile weld travelers to hangers. (Appendix F. Q3)

2. Review results of new inspections being performed for Hatfield Electric hangers that had weld travele" cards with incomplete data. (Section IV.D., page IV-o)

3. Review engineering evaluations of ASME and ANSI B31.1 veld discrepancies.

and AWS weld discrepancies "Acceptable by Calculation". (Appendis C; AppendixT,Qd.andQE) ,

4. Review detailed engineering evaluation of the discrepancies on the ,

50 Hatfield Electric welds with the lowest design margins. (Appendix C; J Exhibit C-2 D.3.a. , page 10 of 15; Appendix F. Q7.) ,

5. Review detailed engineering evaluations of Hatfield Electric weld discrepancies identified from the inspectio'n of highly stressed welds l that were not included in the Reinspection Program. (Appendix C; Exhibit C-2. D.3.b., paga 10 of 15; Appendix F. Q7.)

l I 6. Review the licensees review and evaluation of the results of the I reinspection of welds from which the overlapped portion of the weld i

was to be removed by grinding. (Appendix C; Exhibit C-7, D.5 , page

7. Review the following for Pittsburgh Testingt From the population of Pittsburgh Testing visual weld discrepancies, ,

the most highly stressed welds will be identified. A euttable number ,

of these connections will be reinspected and detailed weld maps will be prepared. Using these veld maps, each of these connections will be evaluated to insure that the welds are capable of transferring the required loads. (Appendix C; Exhibit C-2, D.$. page 14 of 14) h

8. Review inspection acceptance criteria and, interpretations issued during reinspection programs.

i Review a sample of those AWS weld deficiencies "Acceptable by Judgement". j 9.

(Appendix C. Exhibit C-1) r I

10. Review the disposition of ASME weld discrepancies described in Appendix C. Exhibit C-3. pages 3-8.  :
