A Personal Computer-Based Engineering Simulator for High Temperature Gas-Cooled Reactor

：A personal computer(PC)-based engineering simulator for high temperature gas-cooled reactor(HTR)， HTRSIMU has been developed by Institute of Nuclear Energy Technology(INET) of Tsinghua University. HTRSIMU runs on Windows 98 or Windows 2000 operating system， in which the multi- process and multi- monitor techniques are applied.The graphical user interface is friendly and easy to operate.The basic models include the reactor core， the main loop system and steam generator of 10MW high temperature gas- cooled reactor(HTR- 10)， which can be simulated detailed in normal operation and transient accidents.The simulation results are in good agreement with design data and the safety analysis reports of HTR- 10.HTRSIMU can be used as an education al tool to understand the design and operational characteristics of a HTR. In the future， HTRSIMU will provide on- line supports for operators in the main control room of HTR- 10
