Research on Design Improvement of Clock System for AP1000 Nuclear Power Plant

In order to improve the stability and reliability of clock system in AP1000 nuclear power plant, this paper presents an improved design solution for the clock system for AP1000 nuclear power plant. The status is firstly analyzed and the necessity of the improvement is illustrated. Then the improvement countermeasures are described in the sides including the remote backup, network level, operation and maintenance, power optimization, fault alarm and so on. Finally an improved clock system design solution is presented to ensure the stability and reliability of clock system in AP1000 nuclear power plant, which is helpful for the clock system improvement in the construction of AP1000 nuclear power plant and the clock system design improvement for new nuclear power plants.
