Abstract

The article proposes a combined system of emergency cooling of a two-unit nuclear power plant with constantly operating additional steam-turbine units and a two-channel emergency power system with diesel generators. To justify the competitiveness of the proposed combined emergency cooling system compared to the passive residual heat removal systems, we proposed a method based on the defining a multicriteria target function taking into account the influence of the safety factor, as well as technical and economic indicators on the resulting combination effect. Based on the case of the Novovoronezh NPP-2 project, the resulting economic effect from replacement of heat exchangers in the passive heat removal systems for additional low-power steam turbines was determined for two NPP power units. It is shown that the overall capital investments and operating costs are reduced under a slight increase in the risk of core damage, which does not exceed the IAEA standards.

紧急情况下VVER核电厂安全系统的复杂分析——以新沃罗涅日核电站2号项目为例

本文提出了一种双机组核电站应急冷却系统和双通道应急电力系统的组合系统。为了证明所提出的联合应急冷却系统与被动余热排出系统相比的竞争力，我们提出了一种基于定义多标准目标函数的方法，该方法考虑了安全系数以及技术和经济指标对所产生的组合效果的影响。以新沃罗涅日核电站2号机组为例，确定了两台核电机组为新增小功率汽轮机更换被动排热系统换热器的经济效果。结果表明，在堆芯损坏风险略有增加的情况下，总资本投资和业务费用有所减少，这并不超过原子能机构的标准。
