With the combination of increased demand for electric power and advancing age of operating equipment in nuclear power plants, is more important than ever to monitor the condition of plant operation. There are many factors to monitor in nuclear power plant equipment condition. However, one that is frequently overlooked is thermal performance. Often this is an area where plant personnel can find “low hanging fruit” with great return on investment. Often thermal performance analysis can discover better methods to maintain critical plant equipment resulting in more efficient outage activities. Plants also benefit from increasing their operators’ awareness of the importance of thermal performance monitoring to find lost power generation. This paper will discuss proven methods to track, trend, and prioritize thermal performance issues in order to reduce the time from the occurrence of a loss to recovery.

Nuclear power plant is composed of many structures, systems and components. In the design and development of nuclear power plants, in order to improve their safety, more and more designers realized that the standards and methods of design, manufacture and supervision of nuclear facilities and equipment have changed a lot. In the new period, facing the deteriorating environment, green, safety and environmental protection are all the things we have to pursue in our real life. Therefore, it is urgent to develop clean and efficient nuclear power sources and focus on improving the safety, reliability and economy of nuclear power plants. For extreme accidents that are extremely unlikely, the equipment of nuclear power plant should be kept safe and worthy of further exploration under the design extension conditions. In order to ensure nuclear safety, according to the practical experience at home and abroad and the practice of new nuclear power plant, it is proposed to improve the safety classification theory and method of nuclear power plant equipment. At the same time, combined with the in service inspection, equipment identification, quality assurance requirements, maintainability and technical maturity of nuclear power plant equipment, we comprehensively and deeply study the safety classification of nuclear power plant equipment.

Based on many years of research experience of water techno-ecosystems of thermal and nuclear power plants a brief review of the main patterns of formation of the composition, cenotic structure, elements of the functional organization of benthos and periphyton communities was made. It was shown that the composition of zoobenthos and zooperiphyton in some cooling ponds, other technical water bodies and watercourses was quite rich. In addition, due to the rather intensive invasive process, the list of taxa is constantly expanding. Species of tropical and subtropical origin have been recorded. Of particular importance is the invasion of species that may be the cause of bio-hindrances in the operation of power plant equipment. Techno-ecosystems have been studied to varying degrees. One of the most studied for a long time are the cooling ponds of Khmelnitsky and Chernobyl nuclear power plants. Hydrobiological research and monitoring at the first one has been carried out for more than 20 years. It was found that the influence of biotic invasion (invasion of Dreissenidae) may have a significant impact, comparable to extreme technogenic factors, on both the ecosystem and technical water supply facilities. The stages of contourisation and decontourisation processes in the Khmelnitsky NPP techno-ecosystem were established. At the Chernobyl NPP cooling pond, studies were carried out during all periods of the existence of the reservoir and the power plant, until the process of uncontrolled pond descent and transforming it into a unique wetland. Based on the obtained data, practical recommendations relating to the organization of hydrobiological and environmental monitoring, as well as reducing biological hindrances and improving the reliability of power plant equipment have been developed.

Operation And Maintenance

Competition in the electricity market forces producers to achieve — in compliance with safety — efficiency of production as high as possible. This efficiency and heat rate is an important indicator of both the condition of the power plant equipment and the quality of power plant operation. To cope with these challenges, powerful methods are process data reconciliation, statistical data processing of large data sets and process simulation. These functions and methods can be used to obtain useful information about process quality and equipment and sensor health. The paper discusses practical experience from six years of using a thermal performance monitoring and optimization system in the Dukovany nuclear power plant. The system is integrated into the overall nuclear power plant process information system and data warehouse. The system provides information in near real time. The major benefit of the system lies in a deep view into equipment behaviour and process which ensures timely detection and identification of functionality degradation of process and equipment or sensor faults. The system also helps to find and use margins of equipment operation and the overall thermal cycle. Selected practical examples are used to demonstrate specific benefits of the system for operation and maintenance of the Dukovany nuclear power plant. There are examples of equipment fault detection and sensor degradation detection. The optimization function is explained with an example of cooling circuit optimization aimed to increase the delivery of electrical power into the grid. A detailed description of behaviour of the main components can be used for their performance evaluation and their repair planning. The benefit of more accurate determination of parameter values is reflected in more accurate determination of reactor thermal output. The conclusion of the paper provides an overall evaluation of system benefits for operation and maintenance of a nuclear power plant.
