The results of our initial determination of those Festmi II a.
valves that may contain parts cast by Malcolm Foundry Company, Inc.
are not yet cocplete.
Responses from all manufacturers queried have not been received as of this date. Follow-up actions are These continuing to complete this phase of the investigation.
include participation in the NOMIS committee investigation.
i The names of the affected manufacturers supplying safety-related b.
valves to the Fermi II Project are provided on the t.ttached listing.
Our planned action is to formulate a verification, testing and c.
upgrading program once the extent of the potentially faulty l
components situation is determined.
l The schedule for accomplishing this action is indeterminate until d.
such time as the required scopr of the investigation of acceptable mechanical propertiss is established.
This situation necessitates that we request an indefinite extension of Detroit Edison Project Engineering will continue the reporting date.
