Abstract
To install a safety/relief valve(S/RV) discharge line header in addition, on a current S/RV discharge lines in a BWR, can provide a steam release path to many quencher devices. Then the steam blowdown during the S/RV discharge can be more even or symmetrically distributed into the suppression pool in a BWR. The S/RV discharge line header is installed at the middle sections of either all or a portion of S/RV discharge pipes. A current S/RV discharge pipe is installed with a S/RV and a vacuum breaker and its discharge tailpipe is welded with the end of a quencher device inlet. The proposed discharge lines include components such as reactor safety/relief valves, discharge pipes, vacuum breakers, a discharge line header, quencher devices, etc.
