MAINTENANCE METHOD OF FIRST WET SEPARATOR IN ATOMIC POWER VAPOR GENERATOR

摘要

PURPOSE: A maintenance method of first wet separator in atomic power vapor generator is provided to quickly execute a coating process using remote control in order to maintain a wet separator(consisted of a swirl vane and a riser barrel), to reduce the worker's exposure against radiation ray, and to remove the irregularityof coating. CONSTITUTION: A maintenance method of first wet separator in atomic power vapor generator comprises steps of: suppling material, gas and air required to a coating process from outside through a transmission cable; vertically and horizontally moving a high speed gan mounted on a guide rail, to monitoring damaged portions; and controlling all equipments by using a central controller.
