For criticality accidents due to instantaneous insertion of reactivity to the system with non-linear temperature reactivity feedback, an equation has been derived based on one-point kinetics, by which equation the total fission energy is expressed as a function of initial excess reactivity and other kinetics parameters. The results obtained by using the equation and one-point kinetics code, AGNES, were compared to each other to show that the difference between them decreased with increase of excess reactivity from several ten % to 4%.
