... algorithms with their state-of-the art performance, are deployed for automatic anomaly detection in nuclear power plants (NPPs). Nevertheless, in the collected dataset, the knowledge about whether some certain periods are in an abnormal or normal state is available, while for a greater portion of the time...

... Abstract As a large-scale facility with multi-system coupling, the operation safety of nuclear power plant is of great importance to the environment and human society. Accurate monitoring of the overall operation status of nuclear power plants (NPP) is not only the key to ensure its safe...

... Abstract In the design of non-safety I&C system of nuclear power plants, different safety classification and power supply sequence design need to meet the characteristics of system network redundancy and self-healing. Therefore, engineers often use ring network configuration in system...

... Abstract The safety control of hydrogen is a key safety issue that must be considered in the design of nuclear power plant. In order to better study the impact of hydrogen combustion and even deflagration on the nuclear power plant, the Handan Purification Equipment Research Institute has...

... Abstract Earthquake is always an important consideration when constructing nuclear power plants. There are many studies on how to resist or avoid earthquake damage. And recently more and more seismic isolation technology has been applied to nuclear structure in nuclear power plants using...

... Abstract With the development of artificial intelligence technology, various achievements have been realized in data-driven nuclear power plant fault diagnosis. Even endowed with high flexibility and practicability, most of the proposed data-driven methods are based on the same assumptions...

... Abstract With the development of artificial intelligence technology, data-driven methods have become the core of fault diagnosis models in nuclear power plants. Despite the advantages of high flexibility and practicability, data-driven methods may be sensitive to the noise in measurement data...

... Abstract The Moisture Separator Re-heater (MSR) is a key component of Nuclear Power Plants (NPP) both in terms of performance and avoiding erosion and erosion/corrosion damage. Wet steam is usually dried in a MSR by inertial separation using separator elements. Depending on the design of a MSR...

... Abstract Fault detection and diagnosis (FDD) provides safety alarms and diagnostic functions for a nuclear power plant (NPP), which comprises large and complex systems. NPP has a large number of parameters which make it difficult achieve FDD. Now many diagnosis methods have lack of better...

... Abstract When nuclear power plants (NPPs) are in failure state, it may release radioactive substance into the environment. Thus, the safety of NPPs is put forward a high standard. Fault detection and diagnosis (FDD) are significant for NPPs to help operator timely know the state of system...

... Abstract In order to make a comprehensive evaluation of many influencing factors on the site selection of nuclear power plants, and to make a quantitative judgment on the rank of candidate sites, a method of site selection based on analytic hierarchy process (AHP) and fuzzy evaluation...

... thickness measurement should be conducted after 4 years serving. The thickness inspection area is twice times tube diameter downstream of the orifice; furthermore, the suitability assessment rule for similar tubes was established. nuclear power plants Failure Analysis flow accelerated corrosion...

... This paper focuses on the analysis of fatigue life for main steam isolation valve (MSIV) in nuclear power plants (NPPs). The contraction of throat is also in the form of sonic resonance cavity, which causes big vibration and noise. The vibration result in the fretting fatigue, which...

... of particular concerns for the power industry come primarily from cooling water needs, which traditionally constitute the majority of plant water use during the operation phase. This paper examines the water use management challenges confronted by new nuclear power plants in site selection and licensing stages...

... 17 09 2008 A new optical torque measuring method was applied to diagnosis of thermal efficiency of nuclear power plants. The sensor allows torque deformation of the rotor caused by power transmission to be measured without contact. Semiconductor laser beams and small pieces...
