Y-SHAPED FEED WATER AND STEAM HEADER OF STEAM GENERATOR WITH SPIRAL TUBE

摘要

PURPOSE: A Y-shaped water feeding and steam header of a steam generator using a spiral heat transfer tube is provided to be installed in a small space for an integrated nuclear reactor. CONSTITUTION: A nozzle connection unit(111) is connected to a steam nozzle or water feeding nozzle of a nuclear reactor. A flange part(113) is protruded from the lower side of the nozzle connection unit to the outside. An O-ring groove(114) is formed in the flange part. A heat transfer tube connection unit(115,117) is connected to the heat transfer tube of the steam generator. A coupling unit(112) fixes a water feeding and steam header to the water feeding nozzle or steam nozzle in a nuclear reactor.
