Sažetak
This paper describes analysis of thermal-hydraulic conditions in NEK DC Battery and Battery Charger rooms after a postulated break of the SG Blowdown Processing System (SGBD) line. Such break can result in release of the SG water in NEK Intermediate Building which can endanger the safety related electrical equipment. In order to take into account all possibilities, the presence of HVAC (heating, ventilation and air conditioning) ducts must be taken into account, i.e., the HVAC duct can potentially be damaged under the pressure conditions in the rooms where the SGBD break occurs leaving the free path to the DC Battery and Battery Charger rooms.
