Method of preventing the deposition of radioactive corrosion products in nuclear plants
First Claim
1. A method of preventing the deposition of radioactive corrosion products in nuclear plants of the boiling water reactor type, comprising a reactor with a reactor core, onto surfaces outside the reactor core in direct or indirect contact with the reactor water, characterized by the steps of;
- preparing a solution comprising ions of at least one metal by dissolving at least one soluble compound of this metal,decomposing the counter-ion or counter-ions from the compound in the solution to gaseous products,adding the solution to a circuit for reactor water or feed water.

Abstract
Metal ions are added to a circuit (20, 30) for the reactor water or feed water of a nuclear plant. This is accomplished by dissolving a soluble metal compound the counter-ion of which is possible to decompose to gaseous products and water in water in a reaction vessel (41) in an equipment arrangement (40). The solution is subsequently conducted to a series of vessels (42) for the decomposition of the counter-ion. The solution is then possibly transformed to a mixture or a slurry which is conducted to a vessel (43) for degassing the gaseous products before the addition to the circuit (20, 30) for the reactor water or feed water.
