Comments: The picture left below shows the areas examined on each of the (3) pipes inside the 22MT Moat at the North wall . The sketch right below shows the grid layout used for each pipe exam ination. A portion column "A" was obstructed on the SW and FP lines due to the coating not removed as it was not degraded at those locations. The areas examined were representative of the worst case of coating degradation on each line exposed within the Mote excavation.
