The Materials Application Section, Materials Engineering Branch, Division of Engineering has completed its review of this report and its supplements.

We recommend acceptance of the report. The material properties, con-struction, fabrication , nondestructive examinations performed, and fracture mechanics considerations provide reasonable assurance of the structural integrity of the sacrificial shield wall. We judge that the sacrificial shield wall does not present an undue risk to the public health and safety.

Our safety evaluation is attached.
