Engineering Eval-uation of the WNP-2 Sacrificial Shield Wall Supple-ment No. 2" Reference (a) transmitted to the Office of Inspection and Enforcement

( I8E) a report entitled "Engineering Evaluation of the WNP-2 Sacrificial Shield Mall."

Reference (b) transmitted Supplement No.

Additional deficiencies that have been identified and repaired since sub-mittal of Reference (a) do not fall outside the bounding assumptions made in the original SSW evaluation, nor do they invalidate the conclusions, with respect to the integrity of the

SSW, made in that original evaluation.
