Research on Megawatt High Efficiency and Compact New Marine Nuclear Power Plant

核动力装置具有能量密度高、寿期长、不依赖空气等特征,是大型无人潜航器动力源的理想选择。无人潜航器核动力装置必须具备固有安全、轻质紧凑、简单可靠、智能自主控制、抗摇摆等特征,传统压水堆核动力装置难以实现。为解决上述问题,本文提出热管型反应堆与超临界二氧化碳布雷顿循环相耦合的新型核动力装置概念,并针对该新型核动力装置概念,提出海洋热管堆总体设计方案、超临界CO2热力循环方案,构建智能自主控制方法,阐述关键部件研制及安全分析软件开发等方面取得的研究进展,并对后续研究提出展望。

Nuclear power is an ideal power source for large unmanned underwater vehicle(UUV)due to its high energy density,long life span and air independence.The nuclear power source of UUV must have inherent safety,lightweight,compact,simple and reliable,intelligent autonomous control and anti-swing,but the traditional PWR nuclear power is difficult to achieve.To solve these problems,this paper proposed a new nuclear power plant coupled with heat pipe reactor and supercritical carbon dioxide brayton cycle,which has the advantages of“high safety,high power density,high reliability and good expansion ability”,and has a good development prospect Potential.Based on this new concept of nuclear power plant,the marine heat pipe reactor design,supercritical CO_(2) thermal cycle design were studied and presented in this paper,and the intelligent autonomous control method was established.The research progress in the development of key components and safety analysis software were also described,and the prospect of the subsequent research was proposed.
