The condenser vacuun acting cn the diaphragm collapsed the suction screen which resulted in the diaphrag. being punctured in several places.

The disphragm was repaired and the tank put back in service.
The new designed suction screen vill also be installed in Condensate Storage Tank 1A to preclude this type of incident from occurring. As a further precaution, en operating limit has been imposed by ::etropolitan Edison Company to preclude the diaphragn frc= being in contact with the suction screen.
