A mathematical model for the thermal-hydraulic analysis of nuclear power plants

Synchronization of self-sustained thermostatic oscillations in a thermal-hydraulic network

“…Coupling of sub-systems through fluid flow and heat transfer influences the operation of the system as a whole. There are many simulations of the dynamics of thermal-hydraulic systems, such as in nuclear power plants [37]. Thermostats are very common in industrial and building thermal control applications [38,39], and some authors have specifically looked at the modeling of system behavior due to thermostats.…”

Control simulation and study of load rejection transient for AP1000

“…As one of the most import components in the NPP, the problem of developing mathematical models to predict the dynamic behavior of nuclear steam generators has received considerable attention for a long time. In the early studies, many simplified steam generator models ignoring the water level control or the fluid recirculation in the secondary side were adopted (Han, 2000). Since the AP1000 uses the vertical UTSG with the natural circulation flow in the secondary loop, a detailed nonlinear UTSG model with a dynamic boundary between the subcooled heat transfer section and the boiling heat transfer section is adopted in the present study.…”

Support vector regression model based predictive control of water level of U-tube steam generators

“…Guimaraes et al (2008) developed a nine-variable model for UTSGs coupled with a three element controller. Han (2000) developed a steam generator model as part of the overall plant. Lu and Upadhyaya (2005) used a residual space analysis based model primarily intended for fault detection.…”
