Abstract

The neutron spectrum in sample place of online neutron activation analysis system was measured with multiple foil activation technique. According to the neutron fluence level of measuring request， 5 kinds of nonfission nuclear material foils were selected， of which 4 were sensitive to thermal energy region and intermediate energy region， and 1 was sensitive to fast energy region. By measuring the foil activity， the neutron spectrum that was needed to measured was unfolded with the iterative methods SANDII and MSIT. Meanwhile， the process of producing and modifying group cross section were analysed amply. The main factors which have influence on the accuracy of the solution were studied. The discussion for solution was done simply， and the uncertainty of solution was analysed by using the Monte Carlo method.
