Dear Mr. Farrar:

St.bject: Generic Letter 83-28 Item 1.1, Post-Trip Review-Byron Station, Units 1 and 2 By letter dated November 5, 1983, you responded to Generic Letter 83-28 with regard to required actions based on generic implications of Salem ATWS events. The enclosed SER was prepared based upon input from our con-tractor, Science Applications International Corporation (SAI), after the applicable portions of your response to Generic Letter 83-28 were reviewed.

We find that your response does not meet the guidelines developed for post-trip review in the following areas:

1. The method and criteria for comparing the event with expected plant performance.

2. The criteria for the need of independent assessment of the event following the trip.

3. A systematic safety assessment program to assess unscheduled reactor trips.
