PROBLEM TO BE SOLVED: To provide a method for reducing, minimizing or avoiding deposition of metal or metal oxide particles on various constituents in high temperature/high flow rate water by plating one or more noble metals on the surface so as to avoid or minimize corruption on the constituents surface due to interaction between floating particles and the constituent surface. SOLUTION: For minimizing, reducing or avoiding electrostatic deposition of charged particles carried by a coolant on constituent wall surface such as jet pumps in water circulation system of a reactor 10, a constituent surface (mixer 23 for example) is coated with one of noble metal or noble metal alloy. The obtained ZETA potential sign on the constituent surface becomes the same ZETA potential as the charged particles in the coolant flow. COPYRIGHT: (C)2007,JPO&INPIT
