Study on Simulation, Control and Online Assistance Integrated System of 10MW High Temperature Gas-cooled Test Reactor

摘要

Based on the personal computer-based simulation and control integrated platform for the 10MW high temperature gas-cooled reactor, HTRSIMU, an integrated system for simulation, control and online assistance of 10MW high temperature gas-cooled test reactor(HTR-10), has been designed and is still under development by Institute of Nuclear Energy Technology(INET) of Tsinghua University in China. The whole system is based on network environment and includes three subsystems: one called the simulation subsystem (SIMUSUB); the second called the visual control designed subsystem (VCDSUB); and the third called the online assistance subsystem (OASUB). The SIMUSUB consists of three parts: the simulation calculating server (SCS), the main control client (MCC), the data disposal client (DDC) and the results graphic display client (RGDC), all of which can communicate each other via network; The SIMUSUB is intended to analyze and calculate the physical processes of the reactor core, the main loop system and the steam generator, etc., as well as to simulate the normal operation and transient accidents, and the result data can be graphically displayed in the RGDC dynamically. The VCDSUB provides a platform for control system modeling where the control flow systems can be automatically generated and graphically simulated. Based on the data from the control room bus, the OASUB provides some of the reactor core parameters, which are difficult to measure. This whole system can be used as an educational tool to understand the design and operational characteristics of HTR-10, and can also provide online supports for operators in the main control room, or as a convenient powerful tool for HTR control design.
