FIFTH REPORT Description of Deficiency Additional piping was routed through the turbine-driven auxiliary feedwater pump room.
During extended periods of operating the pump, the turbine-driven auxiliary feedwater pump room maxinum 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
' Engineering change notice (ECN) 1435 was initiated to install ventilation fans and alleviate the problem of possibly exceeding the 120 F design maximum upset temperature in the turbine-driven AFW pump room. All design activities required to incorporate, the requirements of ECN 1435 are complete except for the procurement of equipment. Questions have arisen with regard to the vendor's equipment meeting the procurement contract specifications. TVA will submit a final report upon completion of procurement activities.
