ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 TURBINE DRIVEN AUXILIARY FEEDWATER PUMP ROOM TEMPERATURE NCR BLN BLP 8124 BLRD-50-438/81-65, BLRD-50-4;9/81-63 10 CFR 50.55(e)
THIRD INTERIM REPORT Description of Deficiency Additional piping was routed through the turbine-driven auxiliary feedwater pump room. During extended periods of operating the pump, the turbing-driven auxiliary feedwater pump room maximum upset temperature of 120 F, as specified in TVA environmental design criteria N4-50-D749, may be exceeded based on the calculated room cooling load.
Interim Progress TVA has initiated engineering change gotice (ECN) 1435 to alleviate the problem of possibly exceeding the 120 F design maximum upset te=perature in the turbine-driven auxiliary feedwater pump room. TVA drawings have been revised and issued showing ventilation fans that will be installed by this engineering change to provide the necessary cooling. TVA is still awaiting receipt of information from the fan vendor that will be incorporated on the pertinent electrical drawings.
