-March 28,-1983 FILE: B09-13510C SERIAL: BSEP/83-987 Mr. James P. O'Reilly, Director U. S. Nuclear Regulatory Commission Region II, Suite 3100 101 Marietta Street N.W.

Atlanta, GA 30303 4 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NO. 2 DOCATT NO. 50-324 LICENSE NO. DPR-62 SPECIAL REPORT PER TECHNICAL SPECIFICATION 3.7.8 .

Dear Mr.!O'Reilly:

During Unit No._2 power operation--two fire barrier LCOs with respective

issuance dates of March 7 and 8, 1983, were generated on two Control Building fire doors. One of the doors, No. 210, was declared inoperable due to a problem with the door self-closing device. The other door, No. 303, was declared inoperable because of encountered high differential air pressure across the door which prevents automatic self-closure. The door self-closing device of door No. 210 was repaired; however, postmaintenance testing of the r door revealed it would not self-close as a result.of the encountered high r- differential air pressure across the door as. experienced with door No. 303.

As a result of this event,. plant Engineering has been requested to evaluate the subject. differential air pressure problem. Until-the return of the two

~ doors to operability and cancellation of the LCOs, appropriate stationed fire watches at these doors will remain in effect.

Very truly yours, b Wy C. R. Dietz, General Manager Brunswick Steam Electric Plant RMP/dj/LETDJ4 Enclosure L cc: Mr. R. C. DeYoung
