Spent fuels

The purpose of the present work is to describe the methodology applied for determining the activation of these nuclides in fuel assembly structural materials by means of coupled depletion/activation calculations and also to crosscheck the results obtained from two approaches.

An active neutron method for measuring the inherent neutron emission of spent fuel assembly is proposed. The count rate of the inherent neutron emission can be determined by changing intensity of neutron irradiating source. The practical meaning of the method is presented. Some attractive features of the method are shown.
