Title:
WATER SUPPLY SPARGER
Document Type and Number:
Japanese Patent JP2008170319
Kind Code:
A
Abstract:
To uniform the flow rate by stirring flow by causing jet flows from flow nozzles to collide with one another before water jetted from the flow nozzles collides against an in-reactor structure to avoid a high-cycle thermal fatigue phenomenon of the in-reactor structure and accelerate temperature mixture of a supply water flow and discharge flow from a steam separator over the whole circumference within the reactor.
The supply water jetting direction of one or more of four flow nozzles and the supply water jetting direction of the other of the flow nozzles intersects each other at a position nearer to the reactor wall side than to the in-reactor structure in the center side of the reactor in the radial direction.
