The program was presented to the staff by R. A. Muenow of Muenow and Associates who will be performing the non-destructive micro'icismic evaluation of the concrete using the pulse echo method.
The program will define the vertical extention of East-West cracks located at the top of the mat including those beneath the reactor building.
