Abstract and subjects
During the operation of a nuclear system, the isotopic concentration of the device will change as isotopes consume radiation (neutrons, protons, alphas, betas, etc.) and undergo various nuclear reactions [(n, fission), (n, 2n), (n,p), (n,a) , (n,(3), etc.]. Changes in the isotopic concentration over time will result in changes in nuclear system parameters, such as flux, reactivity, and power distribution. These system parameters limit the operational characteristics of the system; therefore, it becomes necessary to calculate these values accurately at many time steps. The study of these reactor parameters with the time-dependent production/depletion of nuclei is known as depletion analysis. [1]
