| Abstract: | The instrument and control system of Xi’an Pulsed Reactor is under the digitized reconstruction, and the code for analyzing the dynamic characteristics of non-pulse transient conditions is essential to provide the real-time variety parameters such as power and fuel temperature. Based on the previous classical analysis code of UHZr Pulsed Reactor, the model for analyzing the dynamic characteristics is built by optimizing the reactor physical model of the previous code and adding new models, and the Xi’an Pulsed Reactor Dynamic Characteristic Analysis Code (XPRDCA) is developed for non-pulse transient analysis. The experiment on the Xi’an Pulsed Reactor is performed. The calculation results of the code and the data obtained from the experiment are compared, and the effect of the temperature reactivity coefficient and the gap heat transfer coefficient on the dynamic characteristics is studied. The calculation results are in good agreement with the experiment data, and the computation speed of the code with optimized model is remarkably improved, and the code could be applied to the design and debugging of the digital instrument and control system. |
