Reliability Design of Marine Nuclear Power Platform Emergency Diesel Generating Sets

Emergency power of nuclear power plant is an important energy to ensure nuclear safety. Starting from the functions and characteristics of the emergency diesel generating sets for the offshore nuclear power platform, the importance of their reliability is analyzed, the specific requirements for reliability are put forward, and then the system design scheme meeting the reliability requirements is given. After that, from the aspects of system composition, start-up and continuous operation ability, independence, redundancy and item classification, this paper gives the concrete measures to guarantee and improve the reliability of the diesel generating sets, meanwhile, makes a comprehensive analysis of the possible system faults during the operation of the sets. Finally, it is pointed out that the design can realize the functions of the emergency diesel generating sets.
