THIRD 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 ho; water heating coils and chilled water cooling coils. Since these fans provide ventilation and cooling of fuel handling engineered safety features (ESP) zones, they are safety related. The heating and cooling coils are not qualiff ed 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 Negotiations are in progress to have the coil manufacturers provide seismic qualification for both the hot water heating coils and the chilled water cooling coils.
