A novel chronometry method is developed to date irradiated nuclear fuels. It is based on the measurement of two Cm isotopic ratios ( 244 Cm/ 246 Cm and 245 Cm/ 246 Cm) and does not require the addition of a yield tracer. The method relies on the decay of 244 Cm while the 245 Cm/ 246 Cm ratio is considered constant after irradiation. Feasibility is demonstrated using different types of irradiated fuels with known irradiation history. A precision of 5 year is reached so far but clear potential for improvement has been identified. The novel chronometry method represents a promising alternative to existing dating techniques for nuclear materials.
