【Abstract】 The computer codes, calculation models, transient results, sensitivity research, design improvement, and safety evaluation used in accident analysis for PRO I Reactor (The Second Pulsed Reactor in China) are introduced. PRC- I Reactor is built in big populous city, so the public pay close attention to reactor safety. Consequently, Some hypothetical accidents are analyzed. They include an uncontrolled control rod withdrawal at rated power, a pulse rod ejection at rated power, and loss of coolant accident. Calculation model which completely depict the principle and process for each accident is established and the relevant analysis code is developed. This work also includes comprehensive computing and analyzing transients for each accident of PRC- I Reactor; the influences on the reactor safety of all kind of sensitive parameters ; evaluating the function of engineered safety feature. The measures to alleviate the consequence of accident are suggested and taken in the construction design of PRC- I Reactor. The properties of reactor safety are comprehensively evaluated. A new advanced calculation model (True Core Uncovered Model) of LOCA of PRC- I Reactor and the relevant code (MCRLOCA) are put forward.更多还原
