3 13 letter is the final report.

The adequacy of the EPI cross-connect modification to correct the generic B&W 177FA Lover Loop P; ant design deficiency on the !!idland Plant has been confirmed. Reference 2, attached, provides evidence of the B&W approval of this corrective action.

The iten noted to require resolution in reference 2 has to do with the 3&W recc=endation for the location of pressure test points in the cross-connect lines. This recc=endation is being included in the detail design.

Detaile.d engineering is proceeding as a normal engineering task and procurement

.to support construction has ec=enced.
