Abstract:
Based on the point reactor model,the program for simulating the burst of reactors,including delay neutron,thermal feedback and reactivity of rod,was developed.The program proves to be suitable to burst reactor by experimental data.The program can describe the process of neutron-intensity change in burst reactors.With the program,the parameters of burst(wave of burst,power of peak and reactivity of reactor) under the condition of dynamic reactivity can be calculated.The calculated result demonstrates that the later the burst is initiated,the greater its power of peak and yield are and that the maximum yield coordinates with the yield under static state.
