Abstract—This paper aims to research the necessity and specific methods to improve the time service of clock system of nuclear power plant. By researching and analyzing the current condition of the whole-plant clock system time service scheme, it propose an improvement scheme of time service system in the aspect of redundancy back-up, system networking, maintenance convenience, and power supply optimization. The research of this paper explores an efficient method to improve time service of clock system and increase reliability. It can provide guidance to the modification of in-service nuclear power plant clock system and the design of new nuclear power plant clock system.

Index Terms—Nuclear power plant, clock system, time service, improvement.
