ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 AUXILARY BUILDING FUEL HANDLING ZONE VENTILATION FANS NCR BLN BLP 8111 BLRD-50-438/81-35, BLRD-50-439/81-38 10 CFR 50.55(e)
FOURTH INTERIM REPORT Description of Deficiency The auxiliary building fuel handling zone ventilation supply air fans are mounted inside the common zone air intake plenums on elevation 686' along with hot water heating coils and chilled water cooling coils. Since these fans provide ventilation and cooling of filel handling engineered safety features (ESP) 7,ones, they are safety related. The heating and cooling coils are not qualified for seismic conditions since they were purchased nonseismic. During a seismic event, a hot water heating coil or chilled water cooling coil could rupture causing flooding of the air intake plenum and subsequent failure of both fuel handling zone ventilation supply air fans.
Interim Progress A contract has been awarded to have the coil manufacturer provide seismic qualification for both the hot water heating coils and the chilled water cooling cools. Additional information will be supplied in the next ceport.
