Case Study

Detroit Edison Fermi 2 Plant Validation
of the Replacement MSR
(Moisture Separator Reheaters)


The Washington Group


The project scope is to provide Dimensional Control services to validate the location and orientation of both nozzles and saddles on the East and West vessels. Meridian Associates performed dimensional validation requirements for the vessel centerline, by observing points around the vessel circumference, at both ends and the center. The center point is obtained by observing point around the nozzle face at the bevel edge. Eight points, conditions permitting, around the face, were observed to determine the plane of nozzle face and determining the N-S and E-W deviation.
