Abrasive blasting decontamination Multi-Nozzle control apparatus and system thereof

摘要

PURPOSE: A spray type decontamination multi-nozzle control device and system using the same are provided to shorten a decontamination process of all steam generator tubules by eliminating contamination of several tubules at the same time. CONSTITUTION: A steam generator(10) comprises a plurality of tubules formed at a regular interval. A spray type decontamination multi-nozzle control device(20) sprays an abrasive provided from outside to two or more tubules. A contamination sensing unit(30) measures each contamination degree of the plurality of tubules. A spray type decontamination remote controlling unit comprises an LM(Linear Motion) guide(40) and a moving rail(50). A system controller(60) controls operation of the spray type decontamination multi-nozzle control device, the spray type decontamination remote controlling unit, and contamination sensing unit.
