COIL ASSEMBLY FOR A CONTROL ROD DRIVER HAVING IMPROVED THERMAL RESISTANCE, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a coil assembly for a control rod driver, wherein the coil for the control rod driver may be improved in terms of thermal resistance characteristics and life cycle to significantly reduce thermal degradation of the coil and reduce the possibility of a control rod descending due to the continuous operation of the driver during automatic load following, thereby improving the safety and economics of a nuclear power plant; and to a method for manufacturing same. To this end, the coil assembly for a control rod driver having improved thermal resistance includes: a coated wire (110) including a coil wire (111) and a polyether ether ketone (PEEK) coating layer (112) surrounding the outer surface of the coil wire (111), wherein the coated wire (110) is wound into multiple layers; a coil coating layer (130) manufactured by filling a varnish into the gap defined between the coated wire (110) wound into multiple layers; an insulation tape layer (120) surrounding the outer surface of the wound layer of the coated wire (110) insulated by the coil coating layer (130); and a silicon molding (140) surrounding the outer surface of the insulation tape layer (120).
