The heat-producing power of weapon-grade plutonium, weapon-grade uranium and depleted uranium per kilogram were calculated through simulation and dynamic decay cascade, the regression line was fitted and analyzed. The temperature fields of the nuclear explosive device raised by Steve Fetter were analyzed according to the simulation results of the heat-producing power of the exothermic materials. The hypothetical models of the nuclear explosive device were modified according to the normal disposal method in industry manufacture, and thermal stress distribution was simulated with the information processed before.
