摘要： PROBLEM TO BE SOLVED: To provide a water supply ring for a heat exchanger having a foreign matter catching function and a water hammer generation prevention function.
SOLUTION: Even when water of a secondary cooling system is taken into a water supply ring main body 53 from a water supply nozzle 40 in a short time to raise level of water of the secondary cooling system in a steam generator 1000, all the amount of steam remaining in the water supply ring main body 53 is exhausted to the outside of the water supply ring main body 53 until level of water of the secondary cooling system reaches height of an upper face of the water supply ring main body 53 by providing many holes 55 for water supply on an upper part face of the water supply ring main body 53. Or, when steam remaining in the water supply ring main body 53 is cooled by water of the secondary cooling system and is shrunk, the steam is absorbed into the water supply ring main body 53 through many holes 55 to suppress "water hammer" phenomenon. Since many holes 55 are provided on the upper part face of the water supply ring main body 53, foreign matter does not drop into the steam generator 1000 through many holes 55 for water supply.
