Abstract

Abstract

The neutron fluence and neutron spectra of CFBR-II （China Fast Burst Reactor II） has been measured by the foils activation technique. SAND-II method is used to unfold neutron spectra. The perturba-tion of the irradiation samples to the neutron spectra are studied. It shows that the irradiation sample can slow down the neutron energy. The neutron fluence measured by this method is coincident with the neutron flu-ence measured by ²³⁹Pu fission chamber.
