Dear Mr. Seyfrit:
River Bend Station Unit 1 Docket No. 50-458 Gulf States Utilities has completed its review of the potential 10CFR 50.55(e) reportable deficiency with regard to the diesel generator building concrete mat " cold joint".
This review indicated that the halting of the concrete placement resulting from equipment failure at the main concrete batch plant I
did not represent a breakdown in the Quality Assurance program, nor did it result in any significant safety problem. A structural analysis of the affected section of the mat indicated that this unplanned construction joint does not impair the structural in-tegrity or performance of the mat.
Based on this review, Gulf States does not consider the diesel generator building concrete mat " cold joint" as a 10CFR 50.55(e) reportable deficiency.
This concludes our response to this item.
Sincerely, E.
