Of the 32 production welds, 13 affecting Unit 1 were repaired and/or re-radiographed as necessary, and the associated.Phillips Getschow NCR's #5207, #5208, and #5209 have been

, closed. The qualifications of 84 PSI welders were evaluated in i i accordance'with the disposition provided in CECO NCR 609 Rev. 2. I l The results of this evaluation confirm the ability of the subject i i welders to' perform sound welds. These steps finalize corrective I i actions for Unit 1.

As indicated above NCR 609 Rev. 2 is now complete. NCR 788 for Unit 2 will be complete following access and inspection of 19 containment spray welds. Resolution of NCR 788 will complete the corrective actions for Unit 2.
