Optical cable used in the instrument and control system of nuclear power plant is the signal transmission medium connected with communication equipment. Optical cable installed in the low irradiation area and some severe irradiation areas in the nuclear island. Compared with conventional commercial optical cable

it has higher requirements in radiation resistance

service life and flame retardant performance. This paper reports design and qualification test of 10kGy optical cable which has been appraised for the first time in China. Review the qualification requirements and test methods of nuclear power optical cables according to the guidance requirements of nuclear power plant quality assurance system and relevant standards. This paper focuses on the thermal aging and irradiation aging test methods and requirements of optical cable identification life.
