Mr. Boyco H.
Grior Page 2 October.6, 1980 services are being expended on' behalf.of approximately ten utilities who are jointly participating in the preparation of a j

Corrective ~ actions associated with this Bulletin fall into two categories, additional safety analyses (e.g.,
shutdown margin adder) and control blade. replacements.
Approximately forty man-days were expended for control blade replacements during Peach Bottom Unit 2's most recent refueling outage.
A similar man power expenditure is expected during Peach Bottom Unit 3's next outage in the spring of 1981.
