The main problem in the operation of nuclear power plants (NPPs) is the scale formation of mineral impurities in an open recirculating system (ORS). The discharge of water from an ORS into natural water bodies can alter the chemical equilibrium of wastewater components, necessitating continuous monitoring. The purpose of this study was to analyse the behaviour of dissolved inorganic salts (DIS) in water within an ORS during water treatment, using the Rivne Nuclear Power Plant (RNPP) as a case study. Moreover, the analysis impact of their discharge with return water in the Styr River. The DIS concentration has a significant impact on the efficiency of the system and the environmental of an ORS power plant. Altogether, each of the DIS components was analysed separately using the standard measurement methods, statistical methods of data processing and correlation analysis. In addition, the annual discharge of the DIS components was calculated, and the amount of discharge was assessed for compliance with the maximum discharge limit. Thus, the impact of the formation of DIS and the variations in their concentration levels upon the discharge of wastewater into a natural water body were examined.
核电站（NPPs）运行中的主要问题是开放循环系统（ORS）中矿物杂质的结垢。从ORS排放到天然水体中的水会改变废水成分的化学平衡，因此需要持续监测。本研究的目的是以里夫内核电站（RNPP）为例，分析水处理过程中ORS内水中溶解无机盐（DIS）的行为。此外，分析其随回水排入斯捷尔河的影响。DIS浓度对系统效率和ORS电厂的环境有重大影响。总共，使用标准测量方法、数据处理统计方法和相关分析分别对每个DIS成分进行了分析。此外，计算了DIS成分的年排放量，并评估了排放量是否符合最大排放限值。因此，研究了DIS形成及其浓度水平变化对废水排放到天然水体中的影响。
