Abstract
Se describe un método para depositar zinc en las superficies de un circuito de refrigeración de una planta de energía nuclear incluye: proporcionar dentro de una porción del circuito de refrigeración una solución de tratamiento que comprende zinc y opcionalmente uno o más metales nobles y/o agentes reductores; permitiendo que la solución de tratamiento permanezca en la porción durante un periodo de tratamiento; y eliminar la solución de tratamiento de la porción. De acuerdo con diversas modalidades, una temperatura promedio de la solución de tratamiento a lo largo del periodo de tratamiento es menor de 150°C o 100°C. De acuerdo con varias modalidades, una temperatura instantánea de la solución de tratamiento permanece por debajo de 150°C o 100°C durante todo el periodo de tratamiento. El tratamiento de deposición de zinc puede aplicarse (1) antes de poner la planta en una operación de generación de energía o (2) durante una interrupción después de la operación de generación de energía y opcionalmente después de una descontaminación química para eliminar cualquier óxido en las superficies de un circuito de refrigeración durante el(los) periodo(s) de operación de energía anterior(es).
