Attachment PY-CEI/NRR-1269 L Page 1 of 2 Nonroutine Report - EPP Sections 4.1 and 5.4.2 On November 2, 1990, the Environmental Monitoring Element was notified of the presence of dead birds in the Unit 1 cooling tower basin. Fifty-four (54) birds vere found during an inspection conducted that afternoon. The species breakdown was as follows:

Species Number Kinglet 45 Vhite crowned sparrov 3 Varbler sp. 2 Black capped chickadee 2

. Vireo 1 Sparrow sp. 1 Total 54 The Perry Nuclear Power Plant was in Cold Shutdown for a Refueling Outage prior to and during this event. The cooling tower basin was drained and had been cleaned on 10/29/90. No lights were on inside the tnver, and no birds were found around the outside of the tower. Veather conditions during the estimated. time of the event included a high pressure system moving in, accompanied by northerly winds and air temperatures in the 40's.

Additional inspections of the Unit I cooling tower basin vere conducted on 11/5/90, 11/6/90, and 11/8/90. The following dead birds were identified as a-result of these inspections.

Species Date' 11/5 11/6 11/8 Number Kinglet 4 Black capped chickadee 1 1 L Sparrov sp. 1 Hourning dove 1 Total 5 2 1 NOTE: No endangered species were identified during any of the inspections referred to in this report.

l The Unit 2 cooling tower basin was cleaned on 11/6/90 and inspected on 11/8/90 to provide comparative information. No dead birds were found during this inspection. The Unit 2 tower is not in operation and no internal vertical supports or baffle plates are installed at this time to serve as obstacles to birds flying into the tover.

,.-o Attachment PY-CEI/NRR-1269 L Page 2 of 2 The cause is believed to be impaction of the birds with internal components and structures of the Unit 1 cooling tover. This unique occurrence is probably associated with fall migration of the birds involved, and the existing plant and weather conditions. A detailed study undertaken at the Davis-Besse Nuclear Power Station documents similar impactions during fall migrations, and correlates them with the occurrence of high pressure systems. In addition, northerly air flows were noted to increase migration of insectivorous birds such as kinglets, which follow different migration paths each year. (Rei'erence Cooling Towers as Obstacles in Bird Migrations, M. Tomme and V. Jackson, Bevling Green State University, 1979).

Although this is an unusual occurrence at the Perry Plant, it is not unusual in industries that utilize tall stacks or towers. No corrective actions are presently planned.

Initial notification of this event was provided to the USNRC Region III office on 11/2/90. Due to the nature of this occurrence, no other agencies were notified.
