摘　　要：核能多联产系统,通过核电站与供热、海水淡化等系统耦合,具有良好的经济、社会和环境效益。本文通过建立核能多联产热经济性模型,分析了同一压水堆核能热电联产和水电联产两种运行模型下的能源成本,探讨了堆型大小对压水堆核能多联产经济性的影响。结果表明,小型堆ACP100热电联产供热单位成本以及水电联产供水单位成本分别为43元/GJ和13元/m^(3)左右。当反应堆规模增大,以ACP1000为例,由于建成单位投资降低,核能热电联产供热单位成本和水电联产供水单位成本大幅下降,可分别降至23元/GJ和8.09元/m^(3)。考虑到工业用蒸汽价格,不同压水堆规模下的核能热电联产技术均具有一定的竞争力。对于北方缺水地区工业用水需求,随着大型压水堆核能水电联产技术发展,其供水价格与自来水厂供水价格相比存在潜在优势。Nuclear polygeneration system,coupled with heating and desalination systems through nuclear power plants,has good economic,social and environmental benefits.In this paper,based on the establishment of thermal economic model for nuclear energy polygeneration,the energy cost of the pressurized water reactor under two operation models of thermopower cogeneration and hydropower cogeneration is analyzed.The influence of reactor size on the economy of pressurized water reactor nuclear operation mode is discussed.The results show that the unit heat supply cost of thermopower cogeneration and the unit water supply cost of hydropower cogeneration for the small-scale reactor ACP100,which are about 43 yuan/GJ and 13 yuan/m^(3),respectively.When the scale of the reactor increases,taking the example of ACP1000,the unit heat supply cost of thermopower cogeneration and the unit water supply cost of hydropower cogeneration will decrease significantly due to the lower unit construction investment,which can be reduced to 23 yuan/GJ and 8.09 yuan/m^(3),respectively.Considering the price of industrial steam,the nuclear cogeneration technologies are competitive under different reactor sizes.Aiming at the industrial water demand of the water-deficient areas in north China,with the development of the hydropower cogeneration technology for large-scale reactor,its water supply price has potential advantages when compared with that of waterworks.
