The GE large vessel blowdown Test No. 5801-15 was simulated with the TRAC-PF1 (Version 7.0) and RELAP5/MOD1 (Cycle 14) codes. The test facility consisted of a pressure vessel, 49-in in diameter by 14-ft long, a 2.5-in diameter converging-diverging nozzle and a blowdown line connected to the center of the upper part of the vessel (elevation from the bottom of the vessel 10.5 ft). The vessel was filled with saturated water up to 5.5 ft at 1060 psia. The test was initiated by rupturing a disc attached at the end of the nozzle. The purpose of this experiment was to study blowdown phenomena such as critical blowdown flow and the level swell during blowdown from a partially water filled vessel. Understanding of these phenomena is essential for the analysis of Loss-of-Coolant (LOCA) and steam generator steam line break accidents. (ERA citation 08:046299)
