+..e July 19, 1979 MEMORANDUM FOR:
Robert Bernero FROM:
Peter Sicilia, Jr.
SUBJECT:
REFINEMENT OF CHRON0 LOGY - TASK GROUP 5 As part of our site visit of July 10-18, 1979, I reviewed several documents.
During this review I documented events that reflected NRC actions, especially those actions that would demonstrate an interface between the NRC and utility; and between major offices within the NRC. This documentation can be used to refine the event chronology documented by Task Group 5.
Attached you will find individual chronologies as described:
Plumlee Interview IE Resident Status Log Procedures Z & EP (limitad review)
Typed Summary of Herbein Transient Log Observation Center Watchlog TMI I Energency Control Center Log I feel we should realize (that) since we are reconstructing NRC's response, we should primarily use data that comes from NRC documents. Where we refine the chronologies using non-NRC type information like four of the six documents attached, we should footnote the entries explaining the source of the information.
