f APR 091979 NRC REACTION TO THREE MILE ISLAND ACCIDENT CHRONOLOGY OF EVENTS (PRELIMINARY)

Attached is a chronology of the communications and actions regarding the notification to NRC of the TMI accident, notifications made by NRC, actions taken and various related communications.

The source for the entries are as shown, and, except for the entries whose source is shown as OC Tape (telephone conversations recorded in the NRC Operations Center in Bethesda), must be treated as preliminary in nature and subject to later confirmation or clarification.

It must also be noted that not all calls to and from the NRC OC were recorded due to saturation of the communications system requiring use of telephone lines not recceded by the twenty channel recorder in the Operations Center.
