Abstract

PROCESO Y EQUIPO DE TRABAJO CON LASER EN UNA ZONA CONTAMINADA DE UNA INSTALACION NUCLEAR. SEGUN ESTE PROCESO, SE EMITE FUERA DE LA ZONA CONTAMINADA (EN 12) UN HAZ LASER PULSADO, SE TRANSPORTA ESTE HAZ HASTA UN EMPLAZAMIENTO CERCANO DE DICHA SUPERFICIE Y, Y EN ESTE EMPLAZAMIENTO SE AMPLIFICA (EN 15) EL HAZ Y SE ENVIA EL HAZ AMPLIFICADO SOBRE DICHA SUPERFICIE. APLICACION A LA DESCONTAMINACION DEL CIRCUITO PRIMARIO DE LOS REACTORES NUCLEARES DE AGUA PRESURIZADA.PROCESS AND WORK EQUIPMENT WITH LASER IN A CONTAMINATED AREA OF A NUCLEAR INSTALLATION. ACCORDING TO THIS PROCESS, A PRESSED LASER BEAM IS TRANSMITTED OUT OF THE CONTAMINATED ZONE (AT 12), THIS BEAM IS TRANSPORTED TO A NEAR LOCATION OF SUCH SURFACE AND, AND IN THIS LOCATION THE BEAM IS AMPLIFIED AND SENT AMPLIFIED ON SUCH SURFACE. APPLICATION TO THE DECONTAMINATION OF THE PRIMARY CIRCUIT OF NUCLEAR REACTORS OF PRESSURIZED WATER.
