A.
The inspectore commented that the unprotected surfaces of carbon steel

materials stored outdoors were heavily oxidized and should be measured for minimum wall thickness after cleanup and' prior to use. Mr. Peck said that CP will perform these measurements at the appropriate time.
(Paragraph 5.b)
B.
The inspectors commented that tape protecting the Cadweld sleeves had become severely deteriorated.
Mr. Peck said that the sleeves would be suitably rewrapped.

piping, had a condition of severe oxidation on the unprotected
,
.
surface weld preparations. The painted sides were streaked I
with rust, and the unpainted backside of the plates and stiffeners were severely rusted. The protective tape, covering the Cadweld thimbles, was severely deteriorated. The inspectors commented that the minimum wall thickness requirements of the plates could
,
possibly be reduced below required thickness by the oxidation.
'
Mr. Peck said that, prior to use, the plate weld preparations and other surface areas will be cleaned and measured to determine that thicknesses are adequate, and the Cadweld thimbles will be retaped.
In addition, he added that techtel is to make an inspection in October 1972, and prepare a report which will include recommenda-tions for any further corrective measures and additional winterizing protection of the materials, components, equipment, and structures.
