Integrated pressurized water reactor (IPWR) usually be equipped with once‐through steam generators (OTSGs). The OTSG has many advantages such as simple mechanical structure, smaller size, and higher heat transfer efficiency. It produces superheated steam but with less inventory in its secondary side. The steam pressure is easily affected by steam flow rate or feed water flow rate. This draws more...
In this research, the corresponding mathematic model was established firstly, thereafter, a splitting-approach was applied to achieve the component equations. In the process of solving equations, a semi-Lagrangian method was used to solve both transient and convection terms, and to solve the pressure equation for incompressible fluid the bound-based projection algorithm was adopt. This study only...
In this paper an integral pressurized water reactor (IPWR) has 100 MW capacity with passive safety features. The design of IPWR focuses on enhancing the safety and reliability of the reactor by employing inherent safety features such as low core power density, elimination of large break loss of coolant accident, etc. In addition, in order to prevent the progression of emergency situations into accident,...
In this paper, computer software is employed to simulate the temperature-field and flow-field of AP1000 PRHR HX, and investigate its heat-transferring and flow characteristic. Through comparative analysis of the distribution of temperature-field and flow-field in different locations at the same time, and the change of temperature-field and flow-field in the same location at different times, heat-transferring...
The paper discussed how to develop simulator of marine power system which is a kind of power system making up of several generators and AC&DC power supply, including general design and simulation mathematical model. According to characteristics and operational requirements of marine power system, a complete set of mathematical models of marine power system were established, which included turbine...
Nuclear Power Plant (NPP) is a complex multi-input & multi-output system, and its operating condition is very complicated, so it is very important to keep NPP safe in a variety of operation conditions including natural circulation, forced circulation, transferring from natural circulation to forced circulation, transferring from forced circulation to natural circulation, etc. It is very necessary...
The paper discussed a Verification and Validation (V&V) type of simulator for Nuclear Power Plant (NPP) which is adopted by Digital Control System (DCS), but DCS simulation is an important part of the V&V type of simulator. The paper proposed a structural scheme and simulation methods about the DCS simulation, and then analyzed control principle and control strategy simulation about DCS Simulation...
Human-machine interface (HMI) design of the main control room (MCR) can obviously affect efficiency, safety operation and control of modern power plants system. A simulation based multi-experts evaluation method for HMI design of MCR was proposed. The functional simulation models of MCR HMI have been developed based on GL Studio. Modularization thinking was used to enhance the modeling efficiency...
According to the currently developing status of the integrated light water reactor, a multi-application integrated light water reactor concept design is proposed in this paper. The arc-shaped reactor core fuel elements are adopted, and once- through steam generator is used to produce steam. The pressurizer is located outside the reactor vessel which uses electric heating method. There are pumps in...
The artificial neural network based subjective expectation evaluation method on software user interface is proposed. The analytic hierarchy process and radial basis functions neural network based subjective expectation evaluation models are established. The two kinds of models are used to evaluate the control system software user interface of power station. Evaluation results show that the radial...
Subjective evaluation of human-computer interaction has the properties of multiple factors influenced, and unknown or uncertain information involved, which leads to the difficulties in the evaluation of human-computer interactive design. In this paper, a novel subjective evaluation method based on grey relational analysis is proposed. By judging the correlative degree between the evaluation criterion...
Proper and rapid identification of malfunctions is of premier importance for the safe operation of nuclear power plants (NPP). Many monitoring or/and diagnosis methodologies based on artificial and computational intelligence have been proposed to aid operator to understand system problems, perform trouble-shooting action and reduce human error under serious pressure. However, because no single method...
